Abstract

The invention discloses a planting method of yew. The disinfection treatment of the seedbed can reduce the occurrence of diseases after sowing, and the soaking treatment of the seeds before sowing can induce the generation of hydrolyzate, so that the large Molecules such as starch are hydrolyzed into various amino acids, making them easy to use for seed embryos, breaking seed dormancy, and promoting seed germination. After the seedlings are thinned, shade with a shading net can prevent the yew seedlings from losing water due to wind and sun. In order not to affect the survival rate due to sun exposure, underground pest control can be carried out at the same time as the above-mentioned pest control, which can further increase the survival rate. The yew cultivated by this planting method has the advantages of simple planting and high survival rate, with huge market potential and broad prospects .

Description

A kind of planting method of Chinese yew

technical field

The invention belongs to the field of nursery stock cultivation, and more specifically, the invention relates to a method for planting yew.

Background technique

Yew is an excellent timber tree. Its heartwood is orange-red and sapwood is light brown. It has clear texture, fine structure, firmness, high density, elasticity, bright color, strong fragrance, little inflexion, and is not easy to crack. Specific applications In the fields of building materials, automobile materials, furniture and joinery. Heartwood sawdust can extract red dye, and leaves and seeds can extract

Taxol against cancer as a therapeutic drug. Southern yew is also an ornamental plant. Its trunk is straight and its leaves are rich in color. After autumn, the arils turn bright red, which is very elegant. It is a tree often used in garden construction. There is a problem of survival rate in the planting method of yew at present.

Contents of the invention

The problem to be solved by the present invention is to provide a planting method of yew.

In order to achieve the above object, the technical scheme that the present invention takes is:

A planting method of yew, comprising the steps of:

(1) Seed collection treatment

First, collect mature and strong fruits from middle-aged yew trees, place them in a large basin, mix them with fine river sand and water in time, and rub the mixed sand seeds with both hands repeatedly on the washing board until the seed coats are broken. Stop when 20-40% of the seed kernel is exposed, wash off the seed coat and sand, and spread it in a cool and ventilated place to dry for later use;

(2) Seedbed preparation

When plowing the land, first spread the ternary compound fertilizer as the base fertilizer, and the application rate is ^50-80kg per 667m2, so that the soil layer is deep plowed and harrowed, leveled, and the bed width is 1.2m, the ditch width is 0.4m, and the bed height is 20-25cm the furrow;

(3) Sowing

Seeds are sown on demand, the plant spacing is 8-12cm, the row spacing is 14-16cm, the thickness of the fine soil cover is 1-2cm, watered thoroughly, the bow shed is covered with agricultural film, the four sides are compacted with soil, and zinc phosphide is also used to make poisonous bait prevent rodent infestation;

(4) Seedling transplanting

When the seedlings grow to 3-4 leaves, thin the seedlings and plant them sparsely in rainy days, remove the dense ones and leave the thin ones, remove the weak ones and leave the strong ones, and then transplant and set the seedlings at a row spacing of 15cm and a row spacing of 25cm;

(5) Weeding and topdressing

After the seedlings are transplanted for 15-25 days, carry out intertillage and weeding 2-4 times, and at the same time use ^3-6kg of urea and 1-3kg of potassium chloride per 667m2 to water, and spray the seedbed as the degree;

(6) Prevention and treatment of pests

Spray with 50% thiophanate-methyl wettable powder 1000 times liquid or 50% carbendazim wettable powder 400 times liquid for control, spray once every 12 days, and spray 2-4 times continuously;

(7) Transplanting and afforestation

Taxus is carefully managed after sowing and emergence. Generally, it can grow to a height of 30-50cm after 2-3 seasons of cultivation. It can be transplanted out of the nursery in winter and spring for afforestation.

Preferably, in the step (2), the seedbed is disinfected by mixing 40-60 kg of fine soil with 2 kg of zinc or 75% pentachloronitrobenzene per 667 m ² and spreading it on the seed bed.

Preferably, seed soaking treatment is performed before sowing in the step (3).

Preferably, the seed soaking treatment is soaking in warm water at 35-45°C for 15-25 minutes, and then soaking in 500mL/kg gibberellin solution for 24-26h.

Preferably, shade with a shade net after thinning the seedlings in step (4).

Preferably, underground pest control is carried out simultaneously with the pest control in the step (6), and the underground pest control method is to use phoxim 800-1200 times liquid or dichlorphos 800-1200 times liquid to spray topsoil in the evening.

Beneficial effects: the present invention provides a planting method of yew. The disinfection treatment of the seedbed can reduce the occurrence of diseases after sowing, and the soaking treatment before sowing can induce the generation of hydrolyzate, so that the Stored macromolecules such as starch are hydrolyzed into various amino acids, making them easy to use for seed embryos, breaking seed dormancy, and promoting seed germination. After the seedlings are thinned, shade nets can be used to prevent yew seedlings from being exposed to wind and sun. Lose water so as not to affect the survival rate due to sun exposure. The above-mentioned pest control and underground pest control can further improve the survival rate. The yew cultivated by this planting method has the advantages of simple planting and high survival rate, and has a huge market potential ,Broad prospects.
