我省栽培紫云英,种子产量不多,须靠外地供应,历年都有缺种现象,成为扩种绿肥中的一个很大障碍。我站为了提高种子产量,对于留种问题曾进行研究。兹将磷肥对于紫云英种子产量关系的结果报导于后。 Asparagus cultivation in our province, the seed yield is small, the need to rely on the field supply, lack of species over the years have become a great obstacle to expanding green manures. In order to increase the seed yield, I studied the issue of remaining seed. The results of the phosphate fertilizer on the relationship between the yield of asparagus seed and seeds are reported hereafter.
