苕子为华中区稻田主要绿肥作物之一。目前存在的问题,一般是田间管理粗放,播种以后既不开沟排水与灌溉,更谈不上施肥,这是促成产量不高的主要原因。为了提高苕子绿色体单位面积产量,除应讲求耕作排灌等技术外,施肥确为苕子增产关键之一。本试验系根据农业合作社现有经济条件,在以小肥养大肥的原则下,进行苕子施肥及施肥期的研究,兹将结果初报于后。
Prickly heat is one of the main green manure crops in central China. The existing problems are generally extensive management in the field. After planting, neither ditching drainage nor irrigation, let alone fertilization, is the main reason contributing to the low yield. In order to improve the yield per unit area of the green shoots, it is one of the keys to increase the yield of the razor clam seeds in addition to the techniques such as irrigation and drainage. This experiment is based on the existing economic conditions of agricultural cooperatives, in the principle of small fattening fat man, carry out fertilizers and fertilizer fertilization period study, the results will be reported later.
