Abstract
The present invention provides a rice seedling cultivating method based on rice husks as substrate by dry soilless cultivation, which relates to a rice seedling cultivating method. The existing rice seedling cultivating method has the problems of low labor efficiency, high production cost, complex procedure, pesticide residue, etc. The operation steps of the method of the invention comprise the processes of crushing and soaking rice husks, mixing, laying, watering, covering, keeping water, fertilizing, etc. The rice seedling method of the invention does not use chemical agent seedling bed to kill weed in the process of seedling cultivation and has the advantages of few working procedure, less time and cost and high work efficiency. Rice seedlings cultivated according to the method of the invention have the advantages of good seedling quality, strong root system, high speed for turning green, strong tilling force, high yield and good rice quality. Compared with rice seedlings cultivated according to the conventional seedling cultivating method with soil, the yield of the seedlings cultivated according to the method of the invention can increase by 5.7% through experimental verification and is an environmental protection project, an ecologic project and a green project, which is favorable for popularization and application.
Description
Technical field:
The present invention relates to the seedling-cultivating method of a kind of paddy rice.
Background technology:
There is the problem that efficiency is low, production cost is high in existing soil seedling-cultivating method, find by literature search, the existing seedling-cultivating method that relates to paddy rice has " paddy rice rice husk soilless breeding seeding technology " (" modernization agricultural ", 2002 08 phases, author: Liu Yankun, Zhang Guojun, Zhang Susheng, Wang Jian), it relates to " utilize the biotechnology fermentation rice husk manufacturing fertilizer that becomes thoroughly decomposed; by with pulverize after the collocation of different-grain diameter rice husk; manual simulation's soil utilize rice husk soilless breeding seeding culture technique ", this technical process exists complex procedures, drawback that cost is high; Another kind of " paddy rice soilless substrate Study on Seedling Cultivation Technique " (" cultivation and rice do " 2001 (5)-14-15, author Zhang Weiquan, Yang Aidong etc.), it relates to " broken stem stalk of raising out during with rice threshing and residual branch stalk, broken leaf shell etc. are done matrix; be equipped with suitable diseases prevention medicament and fertilizer and grow seedlings ", and there are problems such as residue of pesticide in this seedling-cultivating method.
Summary of the invention:
The object of the present invention is to provide a kind of promptly can reduce production costs, can improve again output a kind of is that the paddy rice of matrix does not have native rice seedling on upland field method with the rice husk, and its operating procedure is: a. is broken to powdered rice hulls below 3.5 millimeters; B. sowing is preceding 12~24 hours, rice husk is put into water soak, and before sowing 3-5 hour, rice husk is taken out drainage; When c. sowing, puddle rice husk and nutritional agents evenly after, be laid on the seedbed of leveling compacting, thickness 2-2.5 centimetre, 5~8 cm layer of soil moisture content that water then at the bottom of the bed state that reaches capacity; D. then according to the conventional method sowing, cover the pulverizing rice husk of not mixing nutritional agents, 0.3-0.5 centimetre of rice husk cladding thickness above; E. from one heart stage of rice growing to a leaf, keep the bed ends 5~8 cm layer of soil moisture content state that reaches capacity; G., execute ammonium sulfate 50g for every square metre and get final product during the phase at 1.5 leaf phases and 2.5 leaves; The nutritional agents of c step noted earlier is that the one-tenth by following part by weight is grouped into: nitrogen 2~2.5, phosphorus 1~1.2, potassium 1~1.1, fluorspar powder 5~5.5, bactericide 0.01~0.012, cold-resistance agent 0.10~0.12; The ratio of described nutritional agents and rice husk is: every square metre seedlings growing area applies 0.5 kilogram of nutritional agents, pulverizes 4 kilograms on dried rice husk.Described bactericide is for disliking mould spirit, and described cold-resistance agent is an anti-drought water-retaining agent.Solved the destruction ecology and the environmental pollution problems of growing seedlings and existing with soil with seedling-cultivating method of the present invention, solved the problem that it is difficult that conventional non-irrigated seedling is fetched earth, solved the problem of water mechanically, solved the seedbed exists in residue of pesticide in the rice shoot with weed killer herbicide problem, owing in seedling raising process, do not use chemical agent seedbed weed eradication, save operation, saved time and cost, improved operating efficiency; The seedling quality that brings out with method of the present invention is good, well developed root system, and it is turned green soon, and tillering ability is strong, and output height, rice matter are good, experiment showed, with method of the present invention and can improve output 5.7% than the rice shoot that routine has the seedlings and soil method to bring out; Method of raising seedling of the present invention has improved efficiency, reduces production costs, and helps developing pollution-free food, is an environmental protection project, and ecological project, green project are beneficial to and apply.
