在化肥使用上,不能一直沿襲那種只圖效益、重施氮肥見效快的做法,要科學配方,平衡施肥,化肥和有機肥等合理搭配;在農藥使用上,改變哪種農藥見效快就用哪種農藥,甚至把大田作物農藥使用到蔬菜上的做法;同時要加快蔬菜種植、加工標準化建設。When the concentration is low, 0 - 6 mg / kg, the content of cadmium in the root of alfalfa is lower than in the stern and leaf, but two times higher than the forage hugiene standard of our country. when the concentration is higher than 10mg / kg, the content of cadmium in the root is 20 times higher than the standard, but the content of cadmium in the soil decreased obviously, so alfalfa of this condition is the best alternative for renovating polluted soil. when 200mg / kg znic is added, the poison of cadmium is decreased dramatically with the grow time increasing, the cadmium effect on living number decreased
盆栽試驗中鎘對紫花苜蓿的出苗率、根、莖的生物量的影響與種子的萌發呈現同一規律;鎘在紫花苜蓿體內的含量也與土壤中鎘濃度有關:低濃度0 ? 6mg kg時,紫花苜蓿根部的鎘含量低於莖、葉中的鎘含量,但己超出我國飼料衛生標準2倍,濃度大於10mg / kg時,根部的鎘含量比飼料衛生標準高出20倍,而土壤中鎘含量大大降低,所以此時的紫花苜蓿是修復鎘污染土壤的較好的植物;當加200mg kg鋅后,鎘的毒害作用明顯減小,隨著生長時間的增長,生物量受鎘的影響也在減小,同時紫花苜蓿體內的鎘含量大幅度降低,有些己降到飼料標準以下。Asia ' s green revolution centered on wheat and rice. but experts say no single crop will revolutionize farming in africa because farmers there grow a mixture of different crops
