双季稻“双还双减”机械化生产技术模式
A Mechanized Production Mode of Double Rice with“Double-recycling and Double-reduction”
摘要
Abstract
On the basis of summarizing previous research results ,a mechanized production mode of double rice ( Oryza sativa L.) with “double-recycling and double-reduction”was constructed .The technology mode was assembled with multiple independent technologies including legume crop ( Astragalus sinicus L.) covering, mechanical transplanting for double rice , promoting straw decomposition , high-efficient fertilization , and inte-grated pest ,disease ,and weed controls .The technology mode is suitable for double rice production in the south-ern area of middle reaches of the Yangtze River .The key components of the “double-recycling and double-re-duction” technology mode comprises legume residue retention ,rice straw retention ,reduction in mineral nitro-gen and potassium rates ,mechanical transplanting for double rice ,mechanical tillage and harvest ,and integrat-ed pest ,disease ,and weed controls .Application of the mechanized production mode of double rice with “double-recycling and double-reduction” could simultaneously increase the yield of double rice ,enhance soil fertility , reduce agricultural non-point pollution , and promote the mechanization level of rice production , thus aiding China ’ s grain security and the sustainable development of the double rice cropping system .关键词
