近年来,四川省农科院,浙江省农科院等单位,对培育稀播壮秧和减少插秧本数在单季中稻、双季晚稻以及春花田早稻上的应用进行了较多的试验研究,取得了显著的增产效果。在此基础上,浙江省农科院还提出了水稻“稀、少、平”栽培法及其相应的技术措施,也收到很好的增产效果。但至今稀播少本插在绿肥田早稻上的应用研究尚少,且在生产上,由于绿肥田早稻播种育秧期间,气温较低,秧苗生长较慢,习惯上秧田播种量往往偏高,如果遇到低温阴雨多的年份,秧苗长得更加黄瘦,移栽后返青慢,分蘖
In recent years, Sichuan Academy of Agricultural Sciences, Zhejiang Academy of Agricultural Sciences and other units, to cultivate thinning seedling planting and reducing the number of transplanted seedlings in the single season rice, double late rice and Chunhua Tian early rice on the application of more trials and studies, Achieved remarkable yield increase effect. On this basis, Zhejiang Academy of Agricultural Sciences also proposed a “thin, less, flat” cultivation method of rice and its corresponding technical measures, but also received a good yield increase. However, little research has been done on the application of thin seeding early rice in green manure so far. Due to the low temperature and slow growth of seedlings during early sowing of green manure, the seeding rate of seedling tends to be high in habit. Encounter cold and rainy years, the seedlings grow more yellow thin, turn green slowly after transplanting, tillering
