Bromus prefers fat to thick fat, so organic fertilizer is usually more suitable. It is generally recommended to use cake fertilizer. Bromus is an acidic plant, and rice washing water and rotten vegetable leaves in the kitchen can also be used after decomposition and fermentation. However, in order to enrich the nutrition and make the acidity more suitable, it is suggested to add 1% ferrous sulfate to the rich water cooked by ourselves.

2. What fertilizer is good for Bromus plums?

1, basin soil selection

Bromus pratensis is suitable for growing in loose and fertile deep soil with good drainage performance. Because the roots of plants are developed and planted in shallow flowerpots, it is difficult for Bromus inermis to take root due to environmental restrictions. You can usually choose good flower mud and change the pot soil every two years or so to maintain the nutrient content of the soil. Before transplanting, a proper amount of nutrient solution can be added to the soil to increase soil nutrients and promote the growth of thatch.

2, watering requirements

Water brome should follow the principle that it is wet when it is dry and thoroughly watered when it is watered. Bromus itself doesn't like water, so water it properly. Remember not to water it many times. Plants can't absorb too much water, and deposition in the soil will cause root rot. Natural water, rainwater and river water are usually the best choices for water. If it can't meet the requirements, it can also be watered with tap water that has aged for 2-3 days.

3, light temperature requirements

The environmental temperature of Bromus inermis cultivation should not be lower than 10℃, and the plants will stop growing below this temperature, so attention should be paid to cold protection in winter. Wumei likes semi-cloudy environment, and needs moderate sunshine in spring and autumn and winter, so it can be placed indoors with scattered sunlight. Attention should be paid to shading in summer, and after a period of indoor maintenance, it should be transferred to a cool environment. Alternating environment can make plants grow better.

4, the use of fertilizer

Bromus Bromus cannot be fertilized in the first month of planting. When plants grow vigorously in spring and summer, thin fertilizer can be applied appropriately, a small amount for many times, and added to the soil after being fully diluted. When plants grow slowly in autumn, less fertilizer should be applied. When plants enter dormancy in winter, fertilization should be stopped, and the fertilization time should be chosen as cloudy or evening as far as possible, which is beneficial to the infiltration of fertilizer and water.

3. How to fertilize Bromus

Bromus is of great ornamental value and is often used for bonsai viewing. How to raise bromegrass bonsai? Let's take a look at the cultivation methods of broom bonsai.

1, water

Although Bromus fragrans is a drought-tolerant plant, we should pay more attention to the water content of its soil. Potted strawberries should always keep the soil moist, especially when it is hot in summer and the weather is dry, attention should be paid to watering and spraying water frequently to prevent the soil from drying.

Step 2 apply fertilizer

Although strawberry bonsai is barren-tolerant, soil nutrients can not be ignored during cultivation. During the growth period of Bromus fragrans, except in rainy season, pancake fertilizer water or manure water should be often applied to make the branches and leaves green and bright and grow vigorously.

prune

Bromus fragrans is very resistant to pruning, so it can be pruned once a year after autumn, removing some too dense branches and leaves, and cutting off all kinds of messy branches or long branches to maintain a certain modeling posture and promote its flourishing. Bromus is very strong in germination, so it is necessary to pick the heart in time to make axillary buds sprout side branches. The more times you pick it, the denser the branches and leaves.

How to raise sparrow plum bonsai

As a bonsai cultivation management, Kochia scoparia should be turned over regularly, every 2-3 years, preferably before germination in February-March in spring, in addition to the above conditions. In order to make it grow better, it is necessary to replace the hardened old soil and fill the bottom of the basin with base fertilizer.

5, pest control

The main factor that harms Bromus is insect pests. The branches damaged by longicorn can be removed by a mixture of sulfur and stone. Scale insects suck the juice of Bromus, which can be removed by manual brushing. Therefore, in the process of cultivation and management of pineapple bonsai, we should pay more attention to whether there are these two kinds of pests, so as to nip in the bud.

The above introduces the relevant contents about how to raise broom bonsai. Let's take a look at how to make a broom bonsai.

Production of bonsai brome

Sow and breed. When Bromus inermis seeds are fully mature, they are collected and sown in loose and fertile sandy soil (tidal sediments) or humus soil with good drainage. Transplanting with soil began in the nursery in June 5438+the third year 10 after emergence, and potted plants were generally carried out after 6 years of sowing. It will take at least 65,438+00 years to cultivate a vigorous and elegant broom stump bonsai through sowing and cultivation.

Modeling. The newly excavated Bromus stumps must be trimmed properly. If it is wild Bromus, it needs to be cultivated and stored for a certain period of time before it can be processed and shaped.

(1) After the stump is collected and transported back, it should be properly pruned according to the size of the basin and the physiological habits of the stump, and 0.3% ~ 0.5% potassium permanganate or carbendazim, green milk copper, thiophanate-methyl and other 500 ~ 800 times solutions should be used. Then plant it in the nursery and water it. Wrap moss or grass on old piles and branches, coat the wounds of branches with white latex or vegetable oil, and then seal the big wounds with film.

(2) After the new buds germinate, remove the moss or grass covering the old piles and branches so as not to affect the growth of the buds. At this time, the underground part has not yet taken root, so it is necessary to build a shade shed, strengthen water management, reduce leaf water evaporation and prevent buds from being sunburned. When the buds grow to 1 ~ 2 cm, remove some unsuitable and over-dense buds to ensure the remaining buds to grow sturdily. Bud picking can be carried out in 3 ~ 4 times. (3) After the excavated Bromus stumps survive completely (that is, after 9 ~ 10 months in the second year), they should be observed and studied repeatedly according to the characteristics of the trees, conceived and finalized, and then processed.

④ Preliminary processing. After the Bromus stumps survived completely, they were transplanted with soil for many times with proper amount of water and fertilizer to make the roots retract and further prune the roots and branches to form the skeleton of bonsai. We should pay attention to give full play to its natural beauty, and keep the ridges, wrinkles, unevenness and ancient strangeness on the branches. We should consider the changes of height, size, distance and density, as well as the echo relationship between the front, back, left and right. At the same time, if there are trunk and main branches that need to be bent, it can also be done during this period. The preliminarily processed Bromus stumps can be cultivated for 1 ~ 2 years, and then planted in pots, and then further detailed processing will be carried out. Potting should be carried out before germination in spring.

⑤ Fine machining. According to the conception and design of pineapple bonsai, the following three steps are adopted for artistic treatment.

Pruning: cutting off the long branches of Bromus to promote the germination and growth of lateral buds under the incision. In this way, the Bromus stumps can be branched 2-4 times in 1 year, the number of branches can be increased, and the branch spacing at each level can be shortened, so that the stumps can be formed as soon as possible. In the future, on the basis of maintaining its beautiful appearance, cut off too many dense branches and let the broom stump grow normally.

Binding: According to the thickness of brome branches, select appropriate iron wire, steel wire or aluminum wire, wrap a layer of paper or cloth, and wrap it around the branches in the adjusted direction for bending. You can also tie the branches with brown silk or brown rope, bend them and hang them firmly with brown silk or brown rope. Note that whether it is bound with metal wire or brown wire, it should be loosened 1 time every 3 ~ 4 months to avoid the iron wire falling into the bark after the branches become thicker, which will affect the growth and beauty of the tree.

Rooting: To cultivate bare-rooted Spartina, you can put fertile soil in deep pots or nurseries, and the lower layer is sandy soil, so that new roots can be rooted in the fertile soil, and some sandy soil can be removed from time to time and moved into selected shallow pots, so that the roots are suspended and the stems are exposed, which makes them look vigorous and powerful.

The above are all about the breeding methods of pineapple bonsai, hoping to help everyone.

4. Fertilization method of Bromus inermis bonsai

Bromus likes warm and humid climate. In the cold winter, it is easy to be frozen and not cold-resistant. Bromus is still relatively adaptable, and the soil can grow normally and healthily as long as it is acidic, neutral and calcareous.

Bromus is also a drought-resistant, water-resistant and moisture-resistant plant, and can also adapt to barren land. Like semi-yin and semi-yang, its root system is developed, and it grows mostly on hillsides, roadsides and bushes.

Water and fertilizer: Bromus bonsai is suitable for growing in a humid environment. The soil should be kept moist during the growing period, but it can't accumulate water and is easy to rot. Water more when it is hot in summer, spray some water on leaves and trees to cool down and increase moisture, and water less in winter. During the growing period of Bromus inermis bonsai, pancake fertilizer and manure should be applied every half month. Fertilization management is not needed in summer and winter.

Light and temperature: bonsai bromegrass likes light but is not cold-resistant, so it should be kept in a well-ventilated and humid environment. Shade properly in summer to avoid sun exposure. Bonsai brome is afraid of cold. In northern China, indoor temperature should be kept above 8℃ after late autumn. In the southern part of China, winter can be placed in the leeward and sunny places for winter.

5. Can Bromus be fertilized with urea?

Before planting, the Bromus under the mountain needs pruning. Branches of downhill piles should be trimmed to 15cm long, and redundant side branches and leaves should be cut off. The soil on the roots of brome should be removed and all the rotten roots should be cut off. After being coated with carbendazim and dried, it can be planted.

When breeding Bromus, the temperature should be controlled between 10 ~ 28℃, the soil should be watered when it is dry, and appropriate amounts of nitrogen, phosphorus and urea should be applied in spring and summer, phosphorus and potassium compound fertilizer should be applied in autumn, and fertilization should be stopped in winter.

How to maintain the broom bonsai?

Bromus is divided into big leaves and small leaves, and small leaves are more suitable for bonsai. Bromus chinensis likes light, is more tolerant to shade, has strong adaptability to conditions, and is easy to maintain after being planted in pots.

Upper basin planting

Potting brome should be carried out before germination in February-March in spring, and the pot soil should be loose and fertile slightly acidic soil, such as humus soil, garden soil, pond mud, river sand and base fertilizer. When planting the pot, the roots should be trimmed properly and the leakage holes at the bottom of the pot should be padded to facilitate drainage and ventilation.

Watering requirements

Bromus likes humidity and has certain drought resistance. You can keep the soil slightly wet at ordinary times, and then water it every time after the surface of the soil is dry. If the basin soil is wet for a long time, it will affect root respiration and even lead to root rot. It is hot in summer, and plants need more water, so they can often spray water on the leaves to humidify the environment.

Fertilization management

Too much fertilization in Bromus bonsai can easily lead to white branches and leaves. If there is no fertilizer, the branches will be thinner and the leaves will turn yellow. Spring and summer are the vigorous growth seasons of Bromus, so it is necessary to ensure sufficient nutrients. After entering autumn, the slow growth of plants will decrease. After winter, plants enter dormancy and can stop fertilization.

Pruning modeling

Pruning of Bromus inermis should be carried out in spring and autumn, and the stumps of Bromus inermis have strong germination and vigorous growth in these two seasons. You can prune long branches, overlapping branches, cross branches, dead branches, diseased branches, etc. Bromus species. Strong germination ability, pruning resistance, soft branchlets, easy to shape and bind. Sparrow plums are often thick and finely cut, and can also be shaped by "saving branches and cutting dry". Bromus can be made into inclined dry type, horizontal dry type, bent dry type, dry type, double dry type, cliff type, root lifting type and so on.

The above is my personal opinion on the maintenance of Bromus bonsai. Please correct me if there is anything wrong.

7. Can Bromus inermis be applied with compound fertilizer?

Yes, Bromus can cooperate with root topdressing to increase fertility and improve fertilizer efficiency. Generally, when Bromus inermis germinates, the plants are sprayed with dilute urea fertilizer 1-2 times, and the concentration is controlled at 0. 1%. Dilute potassium dihydrogen phosphate can be sprayed 1 time before and after flowering, and the concentration should be controlled between 0. 1%-0.2%.

If topdressing according to season, because spring and summer are the peak season for Bromus inermis growth, you can topdressing pancake fertilizer or compound fertilizer 2-3 times; Due to the slow growth in autumn, the dressing can be changed once a month 1-2 times; Plants are basically in a state of stagnation in winter, especially in northern China, where deciduous leaves will appear, and fertilization is generally not needed.

8. How often should Bromus inermis be fertilized?

First, if it is placed outdoors, it may be that the soil in the basin is too dry or too wet, especially due to water accumulation and poor drainage after rain.

The second is to put it in a stuffy and unventilated shade indoors for a long time, or suddenly move it to the outdoor for exposure. After the leaves fall, as long as the branches are not withered, there are still residual leaves. Gradually put it in a semi-cool and ventilated outdoor place, coupled with fertilizer and water management, the leaves will grow back after autumn.

Of course, there are some other trivial reasons, such as burning leaves with too much fat, thin leaves without fertilizer, yellow leaves with alkali, yellow leaves without acid, yellow leaves with acid, big pots and small leaves of yellow flowers, yellow leaves caused by pests and diseases and so on.

The standard of watering solution is that the soil in the basin is dry and thoroughly watered at one time, and intermittent watering is prohibited. Bromus leaves will wither if there is no water. At this time, the leaves will be sprayed with water immediately. Then water the basin, be careful not to water it too much, as long as the soil is wet. In summer, the sun is strongly exposed, and the leaves and leaves are yellow with yellow spots (sunburn). It is necessary to spray water in time to cool down and increase humidity. If necessary, add a sunshade net to prevent sun exposure and make it grow normally.

Fertilization Apply thin fertilizer once a week in summer, and don't apply thick fertilizer. If you fertilize too much, you can water it more to remove it. Fertilization can be carried out on schedule to make flowers grow normally and bloom more.

The old leaves in the basin are dry and dull, and the young leaves are yellow and thin. To change a suitable pot, 30% humus should be added to the soil to make the flowers grow normally.

Pest control Bromus should always pay attention to disease prevention and spraying drugs in time during the growth process. The common diseases are powdery mildew, the back of leaves looks like white powder, which makes the leaves yellow and wither, and the back of "brown spot" leaves has black spots and gray mold. The main reason is poor lighting and ventilation. Therefore, it is necessary to treat bromeliads in time.

9. How to fertilize Bromus

1. The yellow leaves of ebony may be caused by insufficient watering. It's time to add water to it. When adding water, it should be poured thoroughly at one time to avoid intermittent watering.

2. It may also be caused by excessive fertilization or high fertilizer concentration. At this time, it is necessary to water the brome, so that the fertilizer can be eliminated.

It is also possible that the flowerpot is too small and the soil is not suitable. At this time, it is necessary to change pots and maintain them with soil with sufficient nutrients.
