细绿萍具有速生、高产、固氮、改土等特点,是水稻田的优质有机肥料。江苏省常熟市任阳公社自1979年开始,每年养殖细绿萍面积稳定在二万亩以上,单季晚稻(苏粳二号)亩产保持在千斤上下,三麦产量也逐年增加。放养细绿萍省工节本,不仅粮食丰收,而且改善了土壤肥力。为进一步探讨其肥效,1981—1982年我们在任阳公社农科大队进行了试验。观察细绿萍和猪圈肥在无机肥配合下对水稻生长及产量的影响;以及对小麦的后效。并测定土壤理化性状的变化。
Fine Green Lupin has a fast-growing, high yield, nitrogen fixation, soil modification and other characteristics, is a high-quality organic fertilizer in paddy fields. Changshu City, Jiangsu Province, Ren Yang commune since 1979, the annual area of fine green Pingtang cultured more than 20000 acres, single-season late rice (Sujing II) per mu to keep in the top and bottom, three wheat production also increased year by year. Green stocking fine green section of the province, not only the harvest of grain, but also improve soil fertility. In order to further explore its fertilizer effect, 1981-1982 we Ren Yang commune agricultural team conducted a trial. Observe the effects of fine green ping and piglet fat on the growth and yield of rice in combination with inorganic fertilizers; and the effect on wheat. And determine the changes of soil physical and chemical properties.
