过去我省紫云英种子产量较低,一般亩产30斤左右,种子不能自给,影响三熟制的发展。1972年以来,我所派人深入基层,认真总结分析紫云英种子产量低的原因,研究出突破亩产百斤的栽培技术。各地应用这套栽培技术,使紫云英种子产量普遍提高40—50%,有的甚至翻一番,亩产达139—141斤。 In the past, the yield of seedlings in our province was relatively low, with about 30 kg per mu in total. The seeds were not self-sufficient and affected the development of the three-cropping system. Since 1972, I have sent people into the grass-roots level, earnestly summed up the analysis of the reasons for the low yield of asparagus seedlings, developed a breakthrough per mu yielding cultivation techniques. Apply this set of cultivation techniques around, so that the yield of asparagus seed generally increased by 40-50%, and some even doubled, reaching 139-141 pounds per mu.
