摘要
对不同稻草覆盖量处理下早稻茬免耕秋玉米不同生育期株高、地上部生物量及产量性状的测定结果表明,稻草覆盖可以增加玉米生物量和子粒产量,覆盖稻草量12000kg·hm-2的处理生物量最大,产量也最高。建议稻草覆盖量在9000～12000kg·hm-2为宜。
The plant height, biomass production and economical characteristics of autumn maize were tested under no-tillage after early-rice in different mulching treatments. The results showed that straw mulching could increase the yield of biomass and grains yield of the crop. In the experiment, Mulching straw at 12 000 kg·hm^-2 could get the highest grain yield and biomass production, and 9 000-12 000 kg·hm^-2 of rice straw was better.
