①及时排灌:花荚期是绿豆需水高峰期,当田间持水量低于70％时即要灌水。灌水宜早,采用小水轻浇和沟灌的方法,一般在初花期和结荚期灌水2次,使土壤持水量保持在80％以上,并一直持续到后期,以利于提高开花量和结荚率,可增产60％左右。绿豆怕淹,土壤过湿易徒长发病,中期遇连阴雨落花落荚严重,地面积水2～3天会导致植株死亡,因此要及时排水。②叶面喷肥:中后期土壤追(?)果差,可采用叶面喷肥的方法。据试验,每亩每次用0.4％磷酸二氧钾和2％尿素混合液50～60公斤,在现蕾、盛花和第一次熟荚摘收后,连喷3次,可增产10～15％。注意叶片正反两面都要均
① timely irrigation: flower pod mung bean is the peak water demand, when the field water content below 70% that is to be irrigated. Irrigation should be early, using the method of light water and furrow irrigation, irrigation in the first flowering and podding usually 2 times, so that the soil water retention remained above 80%, and continued until the late, in order to facilitate increased flowering and pod Rate, can increase about 60%. Mung bean afraid of flooding, the soil is too wet, easy to make long-term disease, the mid-term encounter rainy falling pods serious, groundwater 2 to 3 days will lead to plant death, so timely drainage. ② foliar spray: the late soil chasing (?) Poor fruit, you can use foliar spray method. According to the test, each mu with 0.4% potassium dihydrogen phosphate and 2% urea mixture of 50 to 60 kg, after squaring, full bloom and the first harvest of ripe pods, and even spray 3 times, can increase 10 to 15 %. Note that both sides of the blade should be both positive and negative
