苕子是我区稻田,棉田的主要绿肥作物,生长旺盛,肥效高,增产显著。其留种田常常造成荫蔽,因而产种量低。一般亩产只有八十斤左右,有的只收三、四十斤。为提高苕子产种量,我们用油菜,芸芥等不同作物为苕子支架,进行了小区试验。小区面积为五厘,重复三次,品种是 Prickly heat is my paddy fields, cotton fields, the main green manure crops, strong growth, high efficiency, yield significant. Their stay in the fields often results in shading and therefore low yields. Generally only about eighty pounds per mu, and some only received three or four pounds. In order to improve the yield of prickly heat, we used the different crops of rape (Brassica juncea) and Brassica juncea (Brassica juncea) as prickly heat scaffolds to conduct community trials. The plot area of ​​five percent, repeated three times, the variety is
