Growth period: the growth period of lotus lantern is from April to 10, and the growth period is in summer. In order to apply fertilizer reasonably in the whole growth period, the ratio of potassium: phosphorus: nitrogen = 1: 1: 1 can be adopted and applied once every 6-8 days.
Seedling stage: the amount of nitrogen fertilizer should be increased at seedling stage, and the contents of potassium and phosphorus should be increased at seedling stage, and fertilizer should be applied once every 1 week.
Precautions for operation
The requirements of lotus lamp on fertilizer should not be too high, but it should also maintain its nutritional balance.
Fertilizer must be diluted before use. Too thick fertilizer will make its roots rot, and in severe cases it will cause death. You can make the fertilizer too thin but not too thick.
If it is cultivated in the north, some ferrous sulfate can be added to the fertilizer water, because the water in the north is alkaline, and the soil for cultivating it should be kept in a slightly acidic state.
Very sensitive to salt, you must avoid it when choosing fertilizer.
In the process of fertilization, we must be careful not to let flowers and leaves touch the fertilizer, but also avoid touching the roots to avoid unnecessary harm to plants.
Although it needs moist soil, it should not be too wet, which will rot its roots, so it must be paid attention to when fertilizing.
If the weather is bad, don't forget to postpone fertilization.
Fertilization method of potted camellia
Fertilization of camellia should be carried out selectively according to different growth stages of camellia. Tea peanuts need long-term topdressing, and quick-acting liquid fertilizer and chemical fertilizer should be applied. In the stage of sprouting branches and leaves, nitrogen fertilizer or nitrogen-based mixed fertilizer should be applied. Before flower bud differentiation, bud formation, growth and flowering, it is necessary to apply phosphate fertilizer or phosphorus-based mixed fertilizer. In autumn and winter, it is most suitable to apply mixed fertilizers mainly containing phosphorus and potassium. (1) Nitrogen fertilizer accelerates spring shoots.
Camellia usually begins to shade the spring shoots around 18℃. At this time, the bud-killing fertilizer with nitrogen as the main fertilizer should be applied every 10 day until the spring shoots begin to lignify. Conditional, also can use potassium dihydrogen phosphate 1000 times solution, 1% urea and 300 times rice vinegar mixed diluent for foliar spraying. After repeated spraying of roots and leaves, the spring shoots will grow very luxuriantly, the leaves can be stretched to the maximum extent, and the branches can accumulate rich nutrients, which creates good conditions for flower bud differentiation.
(2) Increase the application of phosphorus and potassium fertilizer to promote flower bud differentiation and form flower buds.
Camellia will have a short semi-dormancy period after the spring shoots are fully drained and lignified. At this time, camellia changed from vegetative growth stage to reproductive growth stage, and flower buds began to differentiate. In order to make camellia bear more buds, it is necessary to apply more phosphorus and potassium fertilizer, and not to apply nitrogen fertilizer or less. If the germination of camellia plants is the main thing, nitrogen fertilizer is still the main thing, and no or less phosphorus fertilizer is applied. Spraying potassium dihydrogen phosphate, a small amount of borax and rice vinegar diluted every/kloc-0.000 times on leaves can not only control the overgrowth of camellia branches, but also promote and shorten the flower bud differentiation time, which is beneficial to bud formation.
(3) Fertilization is not suitable in midsummer, let alone concentrated fertilizer.
It is hot in midsummer, and camellia grows slowly or is in a semi-stagnant state. It is not suitable to apply fertilizer at this time, especially pay attention not to apply thick fertilizer. If the soil is barren, it can be combined with watering and slightly applied with dilute liquid fertilizer to improve the soil quality.
(4) Appropriate application of phosphorus and potassium fertilizer in autumn.
Autumn is crisp and belongs to the nutrient accumulation period of camellia plants. In order to overwinter safely, the mixed fertilizer of phosphorus and potassium fertilizer can be applied once every half month with foliar spraying to promote plant health and improve the cold resistance of camellia.
(5) Dilute liquid phosphorus and potassium fertilizer should be applied in winter.
Camellia in winter enters a semi-dormant state. Camellia has entered the cellar, and its vegetative growth has entered dormancy, so it doesn't need too much fertilizer. However, its reproductive growth has not completely stopped, and it is in the season of flowering or preparing for flowering, so it should be combined with watering and applying dilute phosphorus and potassium liquid fertilizer. Don't apply thick fertilizer.
What should I pay attention to when planting peony?
Peony is characterized by four comforts and four fears, that is, it should be cold and afraid of freezing, warm and afraid of heat, light and shade, dry and afraid of wet. Therefore, peony should be planted in sunny places in the morning, with fertile and loose soil and spacious ventilation, and should not be planted in stagnant water, wet land and gravel land. When planting a platform, the size of the platform depends on the number and size of plants, and the height depends on the original terrain and groundwater level. Generally, the height is 50 100 cm, and the abutment is made of stones or bricks, and some broken tiles or bricks are laid. If the soil is sticky, it should be replaced with culture soil. Culture soil was mixed with 6 parts of land, 3 parts of humus soil and 1 part of rice bran ash. Peony planting is different from other flowers. After peony is planted, it doesn't need irrigation, and it can't be watered with manure. People can bury the soil in winter to keep out the cold, and then open it when it is warm in spring to facilitate growth.
Fertilize soil or land
The flower proverb is well said, clear peony, muddy peony. What does Qing mean? There are a few words in "Flower Mirror" that can be used as a footnote: it is freezing in December and can only be drowned by pig manure. After the vernal equinox, don't fertilize it, wait until the flowers bloom and then use dry fertilizer a little. Watering is especially forbidden in June, which will damage the root system and there will be no flowers in spring. It can be seen that talking clearly does not mean only watering without fertilization. Some people are afraid to fertilize because they say so, which is a misunderstanding of what they say. Fertilization experience is: base fertilizer should be sufficient, compost and cake fertilizer should be applied when planting. Manure. Cover the fat with soil. Top dressing should be controlled, and it can be applied once after flowering in spring, and the fertilizer must be decomposed. Not too thick. No topdressing in summer. Winter fertilizer is the most important fertilization, and winter fertilizer should be combined with soil cultivation. It is not suitable to apply thick fertilizer to new peony, especially to avoid pouring thick fertilizer, otherwise the fleshy roots will rot and die. The source of nutrients is mainly base fertilizer. Although it is in the growing season after flowering, it is still not suitable to apply liquid fertilizer. After planting for one year, solid base fertilizer should also be mainly applied in winter.
water
Peony should not be watered too much, and it is generally not watered in winter. After May, the weather became hotter and hotter. Dry land can be properly watered if it is dry, but it should be dry and not wet. Water the soil only when it is dry. Water accumulation should be prevented in showers and rainy seasons to avoid damaging plants. Storms or persistent rains often harden the soil. When the land is dry after the rain, we must loosen it. Loosening soil in time can improve the air permeability of soil. Peony roots should be buried vertically, and the scarification should be deep. Subsoil topsoil at least three times a year, once after flowering in spring, once after rainy season in summer and once after typhoon and rainstorm in autumn.
Flowering management
If the terminal bud of the main branch is not a bud, but a leaf bud, it should be picked in time to avoid unnecessary growth and affect flowering. Peony branches are fragile. When a flower first blooms, because the flower head is heavy, the branches tend to bend and break easily when encountering strong wind. Therefore, thin bamboo pieces can be used to tie the support, which can not only prevent it from breaking, but also increase the appearance. After the flowers wither, cut off the pedicels to prevent the seeds from setting, so as to ensure the vigorous growth of the plants.
Peony should be covered with grass in winter to prevent cold, and swept and covered with grass in March when the weather is warm.
How to raise potted cologne | Matters needing attention in cologne breeding
Gulong flower originated in Central America and northern South America, and is now widely planted all over the world. Longgu flower has the function of purifying the air, and can absorb the odor such as formaldehyde, benzene, radon and ammonia emitted by newly renovated houses and office buildings. However, it is necessary to be extra careful when planting keels indoors, because there are sharp thorns on the fleshy stems of Longgu Flower, and the white milk in the stems is toxic. Therefore, it is necessary to pay special attention to the place where the dragon bone flower is planted at home to prevent children and the elderly from being stabbed and poisoned. Today, I will briefly introduce the cultivation methods and precautions of cologne for you.
How to raise dragon bone flower?
Soil requirements:
Gu Longhua likes loose and fertile soil rich in humus. Potted soil can be mixed with 1 humus soil and 1 coarse sand, and a small amount of decomposed chicken manure or cow dung can be added to supplement the culture soil.
Temperature conditions:
In summer, it should be kept in a semi-cool environment. It needs plenty of sunshine in winter. If it is placed in a sunny place indoors, the temperature should be kept above 10℃, and if it is lower than 10℃, it is easy to cause freezing injury.
Lighting conditions:
In hot summer, it is necessary to give sufficient shade to the dragon bone flower to facilitate its growth. Indoor display of ornamental dragon bone flowers should be placed in the window near the sun as far as possible, so it is best to see more sunshine.
Watering method:
It is not advisable to water too much in spring. Water every 10 15 days 1 time, but spray water on plants every day to increase air humidity. Water 1 time every day in summer, preferably in the morning or evening.
Fertilization method:
During the growth period of Gulong Flower, apply light fertilizer once every 1520 days. The fertilizer can be granular compound fertilizer or self-made alum fertilizer. But the fertilizer should not be too thick, so as not to cause fertilizer damage and lead to rotten roots.
Trimming and shaping:
In order to prevent plants from premature aging, they should be pruned frequently. Cut off some old branches that don't bloom, and at the same time remove the weak buds that grow below, so that their terminal buds can fully develop and elongate.
Matters needing attention in flower cultivation of Gulong
In the process of cultivation, Longgu Flower is vulnerable to soft rot, stem blight and other diseases. In the early stage of soft rot, brown spots appeared on the column and gradually spread around, then the diseased part softened, the epidermis was eroded, and a viscous foul liquid flowed out. Soft rot develops rapidly, and the whole plant can die in only two or three weeks, but the plant does not lodging and needs to be controlled.
At the onset of stem blight, the whole circle at the bottom turned pale yellow, then spread upward, the green part gradually faded to beige, and white mildew spots grew on the epidermis. After that, the inside of the column was completely rotten, leaving only the epidermis in a dry state, which was broken with a gentle poke by hand, with mucus flowing out, but no stench. Stem blight has also developed rapidly, with some damaged plants lodging and some not lodging.
For soft rot, stem blight and other diseases, the pot soil can be disinfected, such as insolating for 2 ~ 3 days, or scalding with boiling water 1 ~ 2 times. Soak the soil with 500- 1000 times of carbendazim, oxazole, thiophanate-methyl, benomyl and other solutions, and spread the treated soil for one week. It is best to use a new flowerpot, and the old flowerpot should be disinfected if used.
