The cultivation method of a kind of pure ecological Chinese yew
Technical field
What the present invention relates to is gardens technical field of cultivation, and what be specifically related to is the cultivation method of a kind of pure ecological Chinese yew.
Background technology
Chinese yew is also known as Japanese yew, and belong to the rare aiphyllium of first-grade state protection, branch, leaf, skin, root can extract expensive cancer therapy drug---taxol.This medicine whole world year requirement more than 4800 kilograms, and actual year output only has about 250 kilograms, the main cause of restriction Chinese yew output adopts conventional breeding method, because the shell of Chinese yew is comparatively hard, directly cause overall bud ratio lower, and the cycle of emerging is long, irregular, needs 2-3 just can all sprout; Germination rate is high simultaneously, even if the survival rate after sprouting also can only reach 60-70%, and practical chemistry fertilizer a large amount of between whole nursery stage, cause the nursery soil phenomenon that hardens serious, the root system of Chinese yew seedlings is less, further can reduce again overall survival rate after transplanting.
Summary of the invention
The object of the invention is to provide a kind of cultivation method improving the pure ecological Chinese yew of Chinese yew survival rate, and it can solve problem existing in background technology effectively.
A cultivation method for Chinese yew, it is achieved by following steps:
1. the Chinese yew seed first gathered in the crops the previous year, by the shell of hydraulic clip kind device folder except round end one end of Chinese yew seed, is pressing from both sides the kernel that it should be noted that in the process removed and do not crush inside;
2. the wormcast produced in chicken manure process of being searched for food by earthworm and vermiculite, river sand and peat mix obtained a kind of culture matrix in the ratio of 5-8: 2-4: 2-4: 2: 1;
3. this culture matrix is carried out sterilization processing according to the explanation at least one be mixed in carbendazim or thiophanate methyl, and then add Furadan solution and kill the earthworm or earthworm cocoon that may remain in wormcast;
4. by treated culture matrix flat cultivation bed piling strip in booth, and evened up on its surface, then put on seeding unit by the Chinese yew seed through skin breaking and carry out seeding and fabric, the density of fabric is a square meter 180-220 grain;
5. being slightly pressed into being arranged in the Chinese yew cultivated on bed in culture medium, then whole cultivation bed water being irrigated, finally covering one deck straw screen or mat in its surface again;
Can sprout after 6.15-25 days, after sprouting, straw screen or mat be taken off out, water once every 8-14 days after entering Seedling Stage, spray a foliage fertilizer every 20-25 days;
When after 7.7-10 month, height of seedling can reach 5-12cm, i.e. extensible cultivation bed;
The processing method of described foliage fertilizer for: the wormcast produced in chicken manure process that earthworm is searched for food and water in 1: 2 ratio mix after filter a kind of liquid fertilizer obtained, by the liquid fertilizer obtained in 1: 400-600 ratio mix can obtain foliage fertilizer with water.
The thickness of described cultivation bed is 20-40cm.
Owing to have employed above technical scheme, the present invention has following beneficial effect: the process due to whole cultivation is all what to adopt the chicken manure crossed through dealing with earthworm as culture matrix, wherein be rich in the nitrogen that Chinese yew is required in process of growth, phosphorus, potassium also more easily can be absorbed by Chinese yew, the ph value of the chicken manure of simultaneously carrying out a biological disposal upon through earthworm is between 6.0-8.0, just in time within the growth scope that Chinese yew is desirable, it is made to be more conducive to the growth of Chinese yew, and the root system of Chinese yew is also quite flourishing, its emergence rate and the survival rate after transplanting can reach more than 99%, cultivation period shortens greatly simultaneously, within 7-10 month, garden can be gone out.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, being clearly and completely described to the technical scheme in the embodiment of the present invention below.
A cultivation method for Chinese yew, it is achieved by following steps:
1. the Chinese yew seed first gathered in the crops the previous year, by the shell of hydraulic clip kind device folder except round end one end of Chinese yew seed, is pressing from both sides the kernel that it should be noted that in the process removed and do not crush inside;
2. the wormcast produced in chicken manure process of being searched for food by earthworm and vermiculite, river sand and peat mix obtained a kind of culture matrix in the ratio of 5-8: 2-4: 2-4: 2: 1;
3. this culture matrix is carried out sterilization processing according to the explanation at least one be mixed in carbendazim or thiophanate methyl, and then add Furadan solution and kill the earthworm or earthworm cocoon that may remain in wormcast;
4. by treated culture matrix flat cultivation bed piling strip in booth, and evened up on its surface, then put on seeding unit by the Chinese yew seed through skin breaking and carry out seeding and fabric, the density of fabric is a square meter 180-220 grain;
5. being slightly pressed into being arranged in the Chinese yew cultivated on bed in culture medium, then whole cultivation bed water being irrigated, finally covering one deck straw screen or mat in its surface again;
Can sprout after 6.15-25 days, after sprouting, straw screen or mat be taken off out, water once every 8-14 days after entering Seedling Stage, spray a foliage fertilizer every 20-25 days;
When after 7.7-10 month, height of seedling can reach 5-12cm, i.e. extensible cultivation bed;
The processing method of described foliage fertilizer for: the wormcast produced in chicken manure process that earthworm is searched for food and water in 1: 2 ratio mix after filter a kind of liquid fertilizer obtained, by the liquid fertilizer obtained in 1: 400-600 ratio mix can obtain foliage fertilizer with water.
The thickness of described cultivation bed is 20-40cm.
Contained by the chicken manure crossed through dealing with earthworm in this embodiment, the content ratio of N P and K is respectively 1.0-2.5: 0.6-1.2: 0.3-0.9, being desirable Chinese yew culture matrix, having stopped to stir uneven caused burning root problem because adding chemical fertilizer.
Owing to have employed above technical scheme, the present invention has following beneficial effect: the process due to whole cultivation is all what to adopt the chicken manure crossed through dealing with earthworm as culture matrix, wherein be rich in the nitrogen that Chinese yew is required in process of growth, phosphorus, potassium also more easily can be absorbed by Chinese yew, the ph value of the chicken manure of simultaneously carrying out a biological disposal upon through earthworm is between 6.0-8.0, just in time within the growth scope that Chinese yew is desirable, it is made to be more conducive to the growth of Chinese yew, and the root system of Chinese yew is also quite flourishing, its emergence rate and the survival rate after transplanting can reach more than 99%, cultivation period shortens greatly simultaneously, within 7-10 month, garden can be gone out.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art should be appreciated that it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
