氯化铵中氯离子对作物产量和品质都有着重要影响。氯元素是作物必需的营养元素,适量的氯对作物生长和产量有促进作用;过量的氯也会对作物产生毒害。究竟作物可以忍受多大的氯离子浓度?这与土壤、气候、作物种类等均有关。稻田中氯离子浓度的允许范围一般为0.05—0.10%。试验情况供试土壤为四川盆地分布较广的红棕紫泥和灰棕紫泥,每种土壤设9个处理、5个重复,其土壤农化性质如下表。试验分别在分蘖一孕穗期、成熟期采取植株及土壤样品测定氯离子及氮、磷、钾含量,并对不同处理的水稻生育状况、氯害程度及症状、水稻产量
Chloride in ammonium chloride has a major impact on crop yield and quality. Chlorine is an essential nutrient for crops, and an adequate amount of chlorine promotes crop growth and yield; excess chlorine can also poison crops. What crop can tolerate the chloride ion concentration? This and the soil, climate, crop types are related. The allowable range of chloride ion concentration in rice fields is generally 0.05-0.10%. Test conditions The test soil is widely distributed red brown purple and gray brown purple soil in Sichuan Basin. Each soil is provided with 9 treatments and 5 repetitions. The soil agrochemical properties are as follows. The contents of chloride, nitrogen, phosphorus and potassium in plant and soil samples were measured at the booting stage and the booting stage respectively at the tillering stage and the maturing stage. The fertility status, degree and symptom of chlorine damage and rice yield
