四川有近60万平方公里的面积属于亚热带地区,气候温和湿润,地形复杂,野生绿肥资源非常丰富,我们于1977—1978年作了初步调查,现就如何开辟利用,发表一点粗浅意见。一、绿肥资源的丰富性据不完全统计,四川约有11000多种植物,其中豆科植物有85个属404个种,藏量仅次于云南省,居全国第二位。经调查和鉴定已作绿肥(包括藏胞沤粪的原料)和初步认为可作绿肥或饲料的植物有200余种。其中枝叶柔嫩含氮、磷、钾较高,可作绿肥使用的有160多种。
With an area of nearly 600,000 km2 in the subtropical region, Sichuan enjoys a mild climate with a complex climate and rich resources of wild green manures. From 1977 to 1978, we conducted a preliminary survey and published some superficial opinions on how to open up and utilize it. First, the richness of green manure resources According to incomplete statistics, there are about 11,000 kinds of plants in Sichuan, of which there are 85 genera and 404 species of leguminous plants, possessing the second largest reserves in Yunnan province after the acquisition. After investigation and identification of green manures (including Tibetan maceration of raw materials) and initially considered as green manure or feed more than 200 kinds of plants. One of the tender leaves of nitrogen, phosphorus, potassium, can be used for more than 160 kinds of green manure.
