不同畜禽粪肥及不同用量对大葱生长的影响

Effect of different kinds of animal manures and guantity on growth of scallion

通过对大葱施用不同用量的鸡粪、猪粪和牛粪(牛粪为奶牛粪,3种粪都是干粪)的栽培试验表明,上述3种有机肥能明显提高土壤有机质、碱解氮、有效磷和速效钾等养分含量,既能增加大葱的产量,又能改善其品质,从而获得高产优质大葱。从降低有机肥料成本提高肥料利用率考虑,以每公顷施鸡粪、猪粪、牛粪均为15000 kg的用量较为合理;从提高效益和改善品质方面考虑,以每公顷施鸡粪和猪粪均为22500 kg、牛粪15000 kg的用量较为合理。

The effect of different guantity of chicken manure, pig manure and cattle manure on growth scallion were studied. The results showed that the three manures tested obviously increased the nutrient contents of the soil （such as organic matter, alkaline hydrolysis nitrogen, validity phosphorus, quick result potassium, etc.） and improved the quality of scallion with higher product. So we made a guideline for quality and productive scallion production in order to meet the needs of domestic and foreign market. The rational guantity of chicken manure, pig manure and cattle manure were 15000 kg per hectare for each manure in order to decrease manure cost and increaseuse efficiency of fertilizer. When taking benefit and scallion quality into account, the well gnantity should be 22500 kg per hectare for chicken manure and pig manure, and 15000 kg per hectare for cattle manure.
