水稻半旱式自然免耕,是应用生态的技术强化作用,使低产田由无序状态进行有序化组合,提高土壤热效应,加速腐殖质分解,增强土壤内氮、磷、钾及其它资源元素的利用率,促进作物生长、发育,以期达到增产增收的目的。本试验旨在应用半旱式工程技术等物理方法,改变农田结构,提高生物学功能,通过经济效益分析,以阐明因地制宜采取合理的改革措施可获得高效益的途径。
Rice semi-arid natural no-tillage is the application of ecological technology to strengthen the role of the low-yielding fields from disorderly orderly combination of increased soil thermal effect, accelerate the decomposition of humus, soil nitrogen, phosphorus, potassium and other resource elements Utilization, and promote crop growth and development, with a view to achieve the purpose of increasing production and income. The purpose of this experiment is to apply the semi-dry engineering technology and other physical methods to change the structure of farmland and improve the biological function. Through the analysis of economic benefits, we can clarify the ways to obtain high efficiency by adopting reasonable reform measures according to local conditions.
