摘要
当前玉米秸秆还田量逐年加大,由于不能及时腐熟分解,直接影响小麦的正常生长,而增施秸秆腐熟剂是解决该问题的有效办法。试验选用3种秸秆腐熟剂,研究不同处理对秸秆干物质量、纤维素含量、累积净腐熟量、收获指数、小麦产量及其构成因素。结果表明增施秸秆腐熟剂可以显著加速秸秆的腐熟剂速度,尤其是2号腐熟剂对玉米秸秆的腐熟速度快,90d的降解率达86.96%,处理玉米秸秆腐熟效果最好。增施2号秸秆腐熟剂可显著改善漯麦163的单株成穗数、穗粒数、穗数、千粒重、经济产量、生物产量和收获指数等性状。
At present, the amount of corn straw returning to the field is increasing year by year. It can not decompose in time, which directly affects the normal growth of wheat. Thus, increasing the application of straw maturing agent is an effective way to solve this problem. In this research, three kinds of straw maturing agents were selected to research the effects of different treatments on straw dry matter weight, cellulose content, cumulative net ripening, harvest index, wheat yield and its component factors. Results showed that the application of straw maturing agent could significantly accelerate the speed of straw maturing agent, especially maturing agent 2 for corn straw, and the degradation rate of corn straw reached 86.96% after 90 days, treatment of corn straw ripening effect was the best. The number of panicles per plant, grain number per plant, panicle number, 1 000-grain weight, economic yield, biological yield and harvest index of Luomai 163 could be significantly improved by adding straw maturing agent 2.
