宾川县属金沙江流域亚热带燥热气候,蚕豆生育期中由于气温较高,加上栽培上习用以“促”为主的技术措施,结果导致豆株营养生长旺盛,形成株高叶茂,早期封垄,产生大量无效蕾、花、荚而使成荚率降低,产量不高。这种情况,在土壤肥力较高的田块上表现尤为突出。近年来,我们从这一实际出发,对蚕豆高产规律及其栽培技术进行了一些研讨。一、蚕豆“蹲苗”增产的实践“蹲苗”对提高我县低热坝区中上等肥力田块蚕豆产量具有良好的效果。1978年,宾居大队,在技术员的指导下,曾通过延迟 Binchuan County is a subtropical hot climate in the Jinsha River basin. During the growth period of broad bean, due to the relatively high temperature and the technical measures of “promoting” the cultivation, the result is that the bean plant grows vigorously and grows with high leafy foliage, Produce a large number of invalid buds, flowers, pods and reduce the rate of pod, yield is not high. This situation, especially in fields with high soil fertility. In recent years, based on this reality, we have conducted some discussions on the law of high yield of faba bean and its cultivation techniques. First, the broad bean “squat seedlings” increase production practice “Dunmiao” to improve my county low heat dam in the upper fertile field broad bean yield has a good effect. In 1978, the guesthouse brigade, under the guidance of technicians, had passed the delay
