总结产地农民的科学管理经验,蚕豆要获得高产高效,冬春季管理要把住以下五个环节。一、防冻保温蚕百的耐寒力低于大小麦,若长时间处于零下5摄氏度低温的环境中,地上部茎叶即遭冻害,因此,冬季和早春要采取防冻保温措施。方法有:(1)每亩用草木灰1000～1500公斤,集中施在植株根蔸部位;(2)可以用稻草、猪牛粪、谷壳或谷壳灰等覆盖行间,这样可以提高土温2～3摄氏度。二、中耕培土蚕豆是喜光作物,为防止春后杂草与蚕豆争光照,冬季要深锄一次,花前要结合浅锄进行培土,以增加土壤通气性和利于保温,从而促使根系发达和多结根瘤。三、科学施肥蚕豆喜磷、钾肥,因此科学施肥的原则是:“钾肥作底肥,氮肥用苗期,
To sum up the scientific management experience of farmers in producing areas, broad beans to obtain high yield and efficiency, winter and spring management should take the following five links. First, antifreeze heat resistance Silkworm 100 cold resistance is less than the size of wheat, if a long time at minus 5 degrees Celsius low temperature environment, the stems and leaves of the ground that is frost damage, therefore, winter and early spring to take antifreeze insulation measures. Methods: (1) 1000 ~ 1500 kg of grass ash per acre, concentrated in the plant root 蔸 parts; (2) can be straw, pig manure, chaff or chaff ash and other covered lines, which can increase the soil temperature 2 ~ 3 degrees Celsius. Second, cultivation Cultivation of broad beans is a hi light crops, in order to prevent spring weed and beans fight light, deep winter hoe once, combined with shallow hoe before flowering, in order to increase soil aeration and insulation, thereby promoting the root system developed and more Knot nodules. Third, scientific fertilization beans hi phosphorus, potassium, so the principle of scientific fertilization is: "Potash as a base fertilizer, nitrogen fertilizer with seedling stage,
