Toon buds are nutritious and have a unique flavor, many people like to eat. With the growing demand for toon, the natural growth of toon in the wild can no longer meet the demand, we can solve this problem by planting toon artificially.
The planting of toon should pay attention to the propagation, seedling, planting, daily management, harvesting and other aspects of the work, the following in turn to explain.
A, toon propagation method
Toon tree propagation has two ways, one is through seeding propagation, the second is through the division of plant propagation.
1, seeding reproduction is through the seeds of toon, because the germination rate of toon seeds is not high, so you need to catalyze germination before sowing.
The method of germination: put the toon seeds into 30-35 degrees of warm water soaked for 24 hours, and then placed in a constant temperature of 25 degrees of the environment for germination, to be the seeds have dew white, in the low temperature of more than 5 degrees can be sown.
After the seedling emergence, in the true leaves 2-3 pieces is to carry on the inter-seedling, 4-5 pieces of time to carry on the seedling fixing, the plant row spacing 25×15cm.
2, split-plant propagation can also be called tiller propagation, is the use of toon tree tiller out of the seedling, transplanted to seedling nursery land, when the seedling grows to 2 meters, in the fixing of the planting.
Cutting off the roots and tillering can also be used: in early spring, dig a ring-shaped ditch around the toon tree at a depth of about 60 centimeters.
Cut off part of the lateral roots of the toon tree, refill the soil for covering, the broken roots of the toon will grow new seedlings, which can be transplanted and nursed in successive years, and the seedlings can be planted successfully.
Two, toon planting and fertilization
Toon planting before the plot of land should be fertilized, before planting, be sure to apply enough bottom fertilizer, bottom fertilizer to organic fertilizer-based. Generally per mu of land into the rotted organic fertilizer about 5000 kg, calcium superphosphate 100 kg, urea 25 kg.
Fertilizer spread on the surface, and then deep plowing, so that the fertilizer is fully mixed in the soil. After the fertilizer is applied to the ground, it can be planted.
There are two ways of toon cultivation, ordinary cultivation and dwarf dense cultivation. Both ways are the same in the seedling method, the difference is the planting density is different.
Ordinary cultivation planting spacing is large, planting spacing is 7m×5m, dwarf dense planting planting density is large, planting spacing is small, generally the number of plants per acre of land is about 6000 plants.
Dwarf dense planting tree shape can be divided into two, respectively, multi-layer type and clump type.
Multi-layer type is characterized by a taller trunk, layered distribution and stable yield; clump type is characterized by a shorter trunk and more main branches. Choosing different tree forms requires different pruning methods after planting.
Multi-layer type, in the seedling height of about 2 meters to remove the top, to promote lateral buds sprouting, the formation of three layers of backbone branches. The first layer is 70cm from the ground, and the spacing between the top two layers is 60cm and 40cm from the bottom to the top.
Clumping type, the top of the plant is removed when the plant is about 1m high, and then the head is wiped when the lateral branches sprout 20-30cm.
Three, toon planting after the management
Temperature management
After planting a few days after the temperature is maintained at 1-5 degrees in a low-temperature environment conducive to slowing down the seedling, planting a week after the appropriate heating, so that the temperature in the shed to maintain the temperature in the daytime 18-24 degrees, 12-14 degrees at night, after 40-50 days can grow incense. 40-50 days can grow toon buds.
Humidity management
The first planting of the toon seedlings should be maintained at a high humidity, after planting, watering once thoroughly, and later small watering, air humidity is maintained at about 85%, and the air humidity is maintained at 75% after the sprouting of new shoots.
Painting to increase yield
After planting the seedlings, use the twigging treasure on the upper end of the 4-5 dormant buds to paint, can make the buds full, shoots strong, can effectively improve the yield. Pay attention to the concentration of the drug, 1g agent coated buds 100-120 or so.
Light management
The growth of toon needs sufficient light, to ensure that the indoor light is sufficient, the use of non-drip film and keep the shed film clean, can reduce the light refraction.
Four, toon buds harvest
greenhouse greenhouse cultivation of toon, in the right temperature, generally 40-50 days or so, the length of toon buds 15-20cm can be harvested.
The first crop of toon shoots should be harvested by removing the terminal buds on the shoots, and when removing the terminal buds, you can't remove all of the shoots, but keep a part of the shoots to let it continue to sprout.
After the first harvest, the next every 7-10 days can be harvested once, the total **** can be harvested 4-5 times, the harvest to choose in the morning and evening, each time after the picking should be fertilizer watering.
