一、选地、精细整地无公害栽培基地应选择需要空气清洁,3 km内无污染源,大气质量符合无公害农产品基地大气质量标准;土壤符合无公害农产品基地土壤质量标准;灌溉水清洁无污染,符合无公害农产品基地水质标准。红小豆忌连作,重茬和迎茬都不好,同时要求2年以上没有种过豆类作物的地块。北方春小豆生产多为旱作,长期以来形成了以蓄水保墒为中心的耕作制度。因此,合理深耕,精细整地,熟化土壤,蓄水
First, the election, finely ground pollution-free cultivation base should choose the need for clean air, no pollution source within 3 km, the air quality in line with pollution-free agricultural base air quality standards; soil pollution-free agricultural base of soil quality standards; irrigation water clean and pollution- Meet the pollution-free agricultural base water quality standards. Red beans bogey continuous cropping and stubble are not good, at the same time require more than two years have not been planted bean crop plots. North spring bean production mostly dry farming, has long formed a water conservation system as the center of the farming system. Therefore, a reasonable deep plowing, fine preparation, maturation of soil, water storage
