蚕豆是南通地区的主要冬种粮食作物之一。它适应性强,省肥省工,产量高,收入多,同时能在土壤中积累氮素,增进土壤肥力。当前本区夏热作物普遍感到肥料不足,扩种绿肥又与粮争地,因此,因地制宜地适当扩种蚕豆对争取夏秋全面平衡高产有重要的意义。 目前在生产上蚕豆增施磷肥有一定增产效果,但常因土壤条件,施肥种类及时间方法不同而效果各异,现将笔者1961年秋季于南通农专时所做的蚕豆磷肥肥效试验结合专区农科所及本区各地场站资料,归纳
Broad bean is one of the major winter grain crops in Nantong. It is adaptable, save fertilizer and labor, high yield, more income, at the same time can accumulate nitrogen in the soil, improve soil fertility. At present, the summer hot crops in this area generally feel inadequate fertilizers and expanded green manures to compete with grain. Therefore, it is of great significance to strive to achieve comprehensive, balanced and high-yielding summer and fall for the proper expansion of broad bean according to local conditions. Currently in the production of broad beans increased phosphorus fertilizer have a certain yield, but often due to soil conditions, types of fertilizers and different time methods have different effects, now the author in 1961 Nantong Agricultural College made when the test of phosphorus fertilizer efficiency test area Agricultural Institute and the station throughout the district information, summarized
