Description

A kind of Job's tears intensive seedling production method
Technical field
The invention belongs to cultivation method field.Relate to a kind of intensive seedling production method of Job's tears.
Background technology
Job's tears ( coixlachryma-jobil.) for Coix ( coixl.) cereal crop, one of medicinal plant that Ye Shi China area under cultivation is larger.For a long time, Job's tears, as the little ancestor of one " fine strain of millet medicine " crop, is withdrawn to gradually as semi-wild state.In recent years, along with the lifting of health of people theory and the iterative method of agricultural restructuring, take Job's tears as little ancestor's coarse cereals of representative, the development of Chinese Medicine Industry is also in the ascendant.At present, the traditional cultivation pattern of " seed sowing method " is continued to use in the plantation about Job's tears substantially, its regularity of emerging, seedling quality, and the impact by the factor such as kind, environment is comparatively large, and Job's tears output integral level is not high, quality is unstable.Method for culturing and transplanting seedlings is for solution contradiction in large late autumn, drought resisting (or cold) early sowing and strive for season, solution emerge uneven, seedling quality is low etc., and problem quite has superiority, be widely used in the planting process such as paddy rice, vegetables; But Job's tears method is in this regard still deficient.Therefore, be necessary to set up its intensive seedling production method, for the standardized planting supplying method of Job's tears supports.
Summary of the invention
The object of the present invention is to provide and a kind ofly can shorten growing-seedling period and obtain high-quality rice shoot, be suitable for the intensive seedling production method of the Job's tears of spread.
The intensive seedling production method of a kind of Job's tears of the present invention, comprises step as follows:
(1) selection of land is with whole: choose the plot that physical features is smooth, soil fertility is more homogeneous, and soil property with loam or clay as well.Adopt machine or manually plough deeply 20 ~ 25cm, leveling rake carefully, do the seedbed of wide 1.0 ~ 1.5m, the high 10 ~ 15cm in seedbed, has dug drainage ditch, ensures that draining is unimpeded;
(2) seed treatment: choose full seed, clean seed, with the carbendazol wettable powder seed dressing sterilization of 80% before sowing, disinfectant consumption is 0.4% ~ 1% of seed weight;
(3) seeding and seedling raising: control sowing in 30 ~ 40 days before transplanting, sowing quantity 30 ~ 35kg/ mu, the transplanting area of every mu of rice shoot is 10 ~ 30 mu; Use purity nitrogen 10 ~ 15kg/ mu (amounting to urea 21.6 ~ 32.3kg/ mu of nitrogen content 46.4%), P 2o 55 ~ 10kg/ mu (amounts to P 2o 5content 12% superphosphate 41.7 ~ 83.3kg/ mu), K 2o10 ~ 15kg/ mu (amounts to K 2potassium chloride 16.7 ~ 25.0kg/ mu of O content 60%) make base fertilizer; After planting water, to keep, seedbed is moistening is advisable, and after planting carries out overlay film with polyethylene ground film;
(4) field management and transplanting: take off film when seedling bassets and grows to 1 ~ 2cm, 4 ~ 6 leaf phases carried out balled transplanting; In transplanting first about 7 days, spray 50 ~ 200mg/L paclobutrazol (PP 333) solution, and the urea of compounding application 10 ~ 20kg/ mu consumption (mass fraction of N is 46.4%) carries out strong sprout as the fertilizer of getting married before transplanting.
A kind of described Job's tears intensive seedling production method, wherein: the consumption of disinfectant is preferably 0.5% of seed quality.
A kind of described Job's tears intensive seedling production method, wherein: nursery sowing quantity is 35kg/ mu, transplants area 15 mu for every mu.
A kind of described Job's tears intensive seedling production method, wherein: the base fertilizer of seeding and seedling raising is: purity nitrogen 15kg/ mu, P 2o 510kg/ mu, K 2o15kg/ mu.
A kind of described Job's tears intensive seedling production method, wherein: treat that seedling grew to for 6 leaf phases and transplants.
A kind of described Job's tears intensive seedling production method, wherein: fertilizer of getting married (urea of nitrogen content 46.4%) consumption is 20kg/ mu.
