蚕豆是我省的主要夏粮作物之一,它具有成熟期较早,又能改良土壤结构,提高土壤肥力,利用价值高等优点;但在生产栽培中一向被看作懒庄稼,缺少应有的田间加工管理,特别是低温霜冻的影响,产量不稳。我站根据多年的试验及调查研究,从农业气象角度,就昆明地区蚕豆产量不稳的原因,低温冻害指标及低温霜冻规律,蚕豆的防霜等进行初步分析。
Broad bean is one of the main summer grain crops in our province. It has the advantages of earlier maturity, better soil structure, higher soil fertility and higher utilization value. However, it has always been regarded as lazy crop in the field of cultivation and lack of proper field Processing management, especially the impact of low temperature frost, the output is not stable. Based on years of experiments and investigation, from the perspective of agricultural weather, I conducted a preliminary analysis on the causes of instability of broad bean production in Kunming, the indicators of low temperature freezing damage, the frost law of low temperature and the frost protection of broad bean.
