摘要
在庄浪县试验观察了秸秆还田对全膜双垄沟播玉米产量及土壤养分的影响。结果表明,秸秆还田处理的玉米经济性状表现较好。秸秆还田配施秸秆催腐剂能有效提高土壤有机质及氮、磷、钾等速效养分的含量,产量可达11 212.1 kg/hm2,较对照增产10.45%。
Effects of straw returning on yield and soil nutrient of corn ditch sowing in double ridge mulched with plastic films has been observed in the experiment of Zhuanglang county. The results showed that the corn economic traits straw returning was the best. The appheation of straw returning combined application of straw reminder preservatives can effectively increase the available nutrient content of soil organic matter and nitrogen, phosphorus, potassium, etc., the yield could reach 11 212.1 kg/hm^2 and 10.45% more than that control.
