Question 1: How are pine trees planted? As the saying goes, "lovely pine trees are hard to grow"? There is some truth in this statement. Now it's the season to plant pine trees again. Some pot friends want to have some fun, especially some beginners. I don't know how to do it. Take this opportunity to talk about some personal views for reference only. First, choose a suitable digging time, and early spring is the most suitable (that is, early March-May 10 is the growth and germination period of pine trees); Early winter is also feasible (that is, June10-February 12 is the semi-dormant period of pine trees). Second, try to bring soil balls to improve the survival rate. This is very important. Generally speaking, the survival rate of a slightly thicker pine tree is very low if it can't carry the soil ball. If you bring a clay ball, you're halfway there. Third, for newly dug pine trees, it is necessary to reduce the load and cut off at least a quarter of the branches as appropriate to maintain the balance of tree potential, which is conducive to restoring growth and improving the survival rate. Fourth, choose a loose medium to ensure ventilation and filtration. Such as: aeolian fossils (granular), coarse river sand (sand), waste coal cinder (rain after a period of time). In order to improve the survival rate, it is better to plant Pinus tabulaeformis on the ground instead of digging holes. If there are no conditions, pine trees can be planted in wooden boxes or larger pottery pots. Don't go directly to the bonsai basin just to look good. Six, management should try to achieve "wet (branch) dry (root)", especially when the weather is dry, we must insist on frequent water spraying. Seven, for some relatively thick, large pine trees, in summer to timely sunshade, sunshade net should choose 50% model. Eight, strengthen maintenance management, for the new pine planted that year, after the summer, don't transplant. Generally speaking, the pine trees that just survived in those years are often weak, and if they are transplanted at will, the risk is even greater. I just want to transplant, and I'd better move in two years. In autumn, pine trees that have been confirmed to be alive can be properly watered with 1-2 times diluted cake fertilizer and liquid water fertilizer to enhance tree growth. Nine, for pine trees planted for more than two years, it is necessary to restrain the strong and protect the weak, and pay attention to gradually shrinking branches and forcing buds according to the growth situation to prepare for the future potted modeling. Ten, potted pine transplantation, it is best to in early March during the "Arbor Day", for healthier trees, can also be potted in autumn. Generally speaking, "you can't move up or down, and you can't move up or down." This means that if you cut a tree or make a shape, don't transplant it into the pot: if you just go to the pot, don't cut a tree or make a shape.

Question 2: How to cultivate pine bonsai Pine trees are not afraid of cold when planted in the open field, but if potted plants are planted in winter, they should be watered before freezing, otherwise the roots will be frostbitten until they die. If you water it in spring and autumn, it will be thoroughly watered. When it is hot in summer, water it once in the morning and once in the evening. In the vigorous growth period, the decomposed fertilizer should be watered every 7- 10 days. Remember to dilute it, the ratio is about 1 20, that's all.

Question 3: How to plant bonsai pine trees with soil? It is best to use humus. When turning the pan, choose before the plant juice comes out. It is best to start from the end of February to the beginning of March before stabbing, and cut off the long and dense rotten roots before planting. Place the drain hole under the basin with ceramic tile, spread coarse soil on it, then spread a thin layer of soil, and spread another layer of soil on the base fertilizer. Position the pine tree and add soil to be two centimeters lower than the edge of the basin, sit in the basin and water it, and then put the bonsai in a cool place. You can often spray needles.

Question 4: How to plant, manage and fertilize pine trees Due to geographical differences in origin, among the pine trees originating in China, Pinus sylvestris var. mongolica, Pinus yunnanensis and Pinus elliottii are the most hardy and have the lowest requirements for heat. Korean pine doesn't require much heat either. Pinus densiflora, Pinus tabulaeformis, Pinus bungeana, Pinus armandii, Pinus taiwanensis, Pinus taiwanensis and Pinus Bashan are tree species in warm temperate zone and subtropical high altitude area, which need moderate heat. Pinus massoniana, Pinus yunnanensis, Qiao Song and Pinus Simao. Langbianensis is located further south and needs more heat. South Asian pine is a tropical pine with the highest requirement for heat. The requirement of five-needle pine on wet conditions is generally higher than that of two-needle pine, but it also varies from species to species. For example, Pinus koraiensis and Pinus armandii, both five-needle pine, have higher requirements for wet conditions than the latter; Pinus densiflora and Pinus massoniana are both two-needled pines, which require higher water content than Pinus tabulaeformis and Pinus yunnanensis. This is related to the substitution phenomenon with longitude in geographical distribution.

Pine trees can grow on all kinds of soil. Because of the low ash content of needles, they can tolerate poor soil, but when planted in loose and fertile soil, their productivity is high. Pine trees in humid areas are mostly suitable for acidic soil. Some pine trees, such as Pinus bungeana and Pinus tabulaeformis, can adapt to the soil with high calcium content and high pH value, and there are mycorrhizal fungi in the root system of pine trees. The hyphae of ectomycorrhiza mainly form a sheath around the short lateral roots, which is beneficial to the absorption of water and nutrients by the roots. Therefore, inducing mycorrhizal development is very important for the success or failure of some pine afforestation. Most pine trees can't grow on saline-alkali land, so they can't grow near the seashore. But some pine trees, such as black pine introduced into China from Japan, have strong salt tolerance.

Most pines, especially apricot pines, are light-sheltered trees with weak shade tolerance. Its appearance is sparse crown and natural pruning height; Physiologically, the compensation point is low; Most of them are pioneer trees with forest characteristics. When virgin forests are destroyed or burned, they can easily develop and occupy * * * space. For example, the evergreen broad-leaved forest in the south of China is easily replaced by Pinus massoniana or Pinus yunnanensis. However, these pine forests are not stable. When they form a suitable forest environment, for some basic trees that are relatively shade-tolerant, broad-leaved trees such as Populus davidiana and Betula platyphylla appear, and then Korean pine appears. Because Korean pine has the characteristics of shade tolerance and longevity, it finally regained its dominant position. In addition to the substitution of Korean pine, Populus davidiana and birch, there is also the substitution of Mongolian oak (Quercus mongolica) and Korean pine.

Pine has a xerophytic structure: narrow leaves, developed cuticle, small ratio of surface area to volume, depressed stomata and fully developed thick-walled tissue. Physiologically, they are more tolerant of water shortage than mesophyll trees. Ecology, pine trees are xerophytes. Most pine trees distributed in different climatic zones can grow in rocky and shallow arid habitats. Generally speaking, the drought resistance of two-needle pine is stronger than that of five-needle pine. Too much soil moisture is bad for the growth of pine trees.

Selection of nursery land

Nursery land should be sandy loam with loose soil and deep soil layer, and the land with flat terrain and good irrigation and drainage conditions is better. There are mycorrhizal fungi in the root system of Pinus bungeana, which has a good effect on promoting the growth of seedlings, that is, it can promote the root system of seedlings to absorb water and nutrients in the soil and improve the drought and disease resistance of seedlings. Therefore, Pinus bungeana nursery is suitable for continuous cropping.

Sand storage and accelerated germination of seeds

Indoor sofa buds are used in winter. Accelerating germination in sand storage should be carried out before soil freezing. Choose a clean house with intact doors and windows for comprehensive disinfection, pile up sterilized pure sand with humidity of about 60% indoors, pack seeds and sand with pure cloth bags at the ratio of 1: 3, so that the volume of sand and seeds accounts for 30% ~ 40% of the total volume of the cloth bags, then bury the cloth bags into the sand evenly, cover the sand piles with grass curtains, and pay attention to ventilation, moisture preservation and antifreeze. Sowing can be done when there are 40% ~ 50% cracks in the second year.

The seedling raising method is container seedling raising or high-low bed seedling raising. Seedbed seedling is raised by drilling, with sowing amount of 40-50kg per mu, covered with plastic film or straw, and the covered straw should be disinfected with formalin or carbendazim solution with concentration of 65438 0%.

Seedling management

25 ~ 30 days after sowing, the seedlings are unearthed with shells, and the shells fall off on their own in about 15 days. In this period, it is necessary to prevent the destruction of birds and animals. The prevention of damping-off disease should be strengthened after the seed shell falls off, and the seedlings should be sprayed alternately with carbendazim and ferrous sulfate 2 ~ 3 times a week. Use 0.3% ~ 0.5% ferrous sulfate aqueous solution, one person in front sprays the medicine, and the other person washes it with water, otherwise it will easily cause phytotoxicity. In the process of seedling growth, water should be properly and timely, and attention should be paid to loosening the soil and weeding.

Pinus bungeana seedlings grow slowly, only 4 cm ~ 5 cm in the first year, 10cm in the second year, 30 cm ~ 40 cm in the 4 ~ 5 years old seedlings, 10 years old seedlings1m. In the process of cultivation, seedlings can only be cultivated after two or three transplants ... >>

Question 5: How to plant pine saplings with high survival rate? We have a video of pine planting management technology. Let you see the personal demonstration and blessing of experts and technicians. Teach you how to plant pine trees by hand. Please contact dtgcjsyjs@sina if necessary.

Question 6: How many years can pine trees be sold? How can they grow faster? If I were you, I would plant slash pine. If the water content is enough, I can sell them for more than ten years by adding fertilizer twice a year. Of course, the cost is high.

Question 7: How can the survival rate of pine trees be high? Generally speaking, pine trees should be planted according to their habits.

Pine trees like acidic soil, but they are afraid of waterlogging. When planting, the gravel content of the soil should be increased (that is, the coarse sand should reach about 30%) to ensure the ventilation and water permeability of the soil. There is also a saying that "if pine trees want to grow long, you must hear the sound of hoes on the hills", and you should plant them densely so that trees and soil can be well combined.

Question 8: How to plant pine seeds? The method of sowing and propagation is simple and can produce a large number of flower seedlings at one time, so it occupies a major position in the propagation method. When sowing and breeding, we should pay attention to the following points:

1, the seed quality of flowers is better.

"Good plants produce good seedlings", and excellent flower seeds are the basis of strong seedlings. When sowing, we must choose fresh seeds with large and full seeds, pure varieties and no pests and diseases. It is best to collect and preserve the flower seeds yourself.

2. The sowing date should be appropriate.

The sowing date of flowers is regular. Generally, annual flowers and open-field woody flowers are planted in March and April in spring, when the average daily temperature is stable at 15 degrees; Most biennial flowers in the open field are planted in August-September in autumn. The sowing date of greenhouse flowers often depends on the required flowering period, and there is no strict seasonal restriction, but generally the coldest and hottest seasons should be avoided.

Before sowing, the seeds should germinate first.

Flower seeds should absorb enough water before germination, and then the radicle can be elongated and germinated slowly. In order to meet the temperature, moisture and oxygen required for seed germination, it is best to put the seeds into gauze bags, soak them in 40℃ warm water for 24 hours before sowing, then spread them on wet gauze, keep the gauze moist, and sow them after the radicle of the seeds breaks through the seed coat.

4. Sowing depth should be reasonable

Flower seeds are divided into four grades: large, medium, small and fine. The diameter of large seeds is generally above 1 cm; The diameter of medium-sized seeds is 0.4-1cm; The diameter of small seeds is below 0. 1 cm. No matter large, medium or small seeds, the sowing depth is 2-3 times the diameter of the seeds. Sow large seeds on the seedbed, the hole depth is 2-3 times of the seed diameter, then cover the soil and level the bed surface; Sprinkle medium and small seeds on the bed surface first, and then cover it with a thin layer of soil; Granular seeds do not need to be covered with soil.
