不同秸秆还田量对旱地全膜双垄沟播土壤水分及玉米生长的影响
Effect of different straw treatments on soil water and growth of maize with film mulched double-furrow sowing in dry land
摘要
Abstract
The study aims to investigate the effect of different straw treatments on soil water ,yield and growth of maize with film mulched double-furrow sowing in dry land .For treatments were as follows:the amounts of maize straw of 6 000 kg·hm-2(low level returning) ,9 000 kg·hm-2 (medium level returning) ,12 000 kg·hm-2 (high level return-ing ) ,and the control treatment with no straw returning .The results showed that the soil water increased with amount of straw at early growing stage ,especially during emergence stage ,increased by 6 .07% ,1 .24% and 0 .31% for high , middle and low treatments ,respectively .During tasseling stage ,the increasing effect was in the order of low-level>mid-level>no straw>high-level ,the order of leaf area was high-level>mid-level returning>low-level>no straw treatment , and the order of water consumption was high-level>no straw>mid-level>low-level treatment .The yield and water use efficiency of 6 000 kg·hm-2 treatment (low-level returning ) was highest ,indicating that is suitable for extension in semi arid regions .关键词
