Method for growing nuisance free selenium-rich rice by using biological technique

Abstract

The invention relates to a method for planting pollution-free rice rich in selenium by adopting biotechnology, belonging to a planting method of plants; the planting method comprises the steps of land selection, soil preparation, application of the soil activator Medina, variety selection and seed treatment, seedling strengthening by means of dry raising and spaced planting cultivation, timely rice transplanting and reasonable compact planting, adequate fertilization, scientific irrigation, adoption of selenium supplementing and transforming technology, comprehensive prevention and control of diseases and pests, harvesting and threshing, drying and storing. The method of the invention has obvious effect; proved by field production trials, the application of the biologics of the Medina can increase the plant yield by 20 percent to 40 percent and decrease the fertilizer dosage by 25 percent to 50 percent and improve the rate of emergence in saline and alkali waste lands by 40 percent to 80 percent; the method can overcome diseases of continuous cropping effectively, eliminate soil crusting and optimizing greenhouses, etc. so as to preserve the soil properties of land capability.
