从湖南实际出发,以双季稻田粮食年亩产过吨粮为目标,将多项科技成果和传统技术相结台,综合组装出新型技术体系,即资源配置、耕作栽培、种养加结合转化增值、开发组织管理技术体系。结果表明,采取N、P、K三要素配合,“双两大”栽培,杂交水稻与高产栽培技术配套的吨稂田开发的技术效应显著;经济效益明显,其劳动净产值率、物质费用收益率、成本产值率表现为吨粮田>中、高产田>低产田;土壤营养状况基本稳定。 Starting from the reality of Hunan Province, we aim to achieve the goal of producing more tons of grain per mu in grain crops per mu in the double-season paddy fields by combining a number of scientific and technological achievements with traditional technologies and integrating new technological systems, namely resource allocation, cultivation and cultivation, planting and breeding, Value-added, development of organizational management technology system. The results showed that the technical effect of developing tandan with hybrid rice and “double big two” cultivation and hybrid rice and high-yielding cultivation technology was significant with the combination of three factors of N, P and K; obvious economic benefits, the net labor productivity value, material cost Yield, cost The output value of the performance of the grain field> medium and high yield field> low yield field; soil nutrient status basically stable.
