以常规覆膜 (ck1)和起垄覆膜 (ck2 )为对照 ,探讨了玉米采取沟垄种植 ,并用油毡替代地膜覆盖垄面的集水效应对耕层地温、植株生长发育及产量和水分生产效率的影响。结果表明 ,用油毡替代地膜后 ,雨后种植沟内聚集的降水是 ck1的 2 .0 7倍 ,是 ck2 的 1 .2 4倍 ;耕层 0 cm～ 2 0 cm地温分别较 ck1和 ck2 低 1 .6℃和 0 .8℃ ,对控制玉米营养生长 ,促进生殖生长和缓解常规覆膜玉米的早衰现象十分有效 ,总生育期较 ck1和 ck2 分别延长了 1 4d和 6d,较二者的增产幅度达 2 7.4%和 1 9.7% ,水分生产效率也提高了 2 .2 5kg/(hm2 · mm)和 1 .35kg/(hm2 ·mm)。
Taking conventional film (ck1) and ridge film (ck2) as control, the effect of catchment and furrow planting of maize on ridge planting was studied. The effects of water collection on soil temperature, plant growth, yield and water production The impact of efficiency. The results showed that after replacing the film with linoleum, the accumulated rainfall in the planting ditch after rain was 2.07 times of ck1 and 1.2.4 times of ck2, and the soil temperature of 0 cm ~ 20 cm of top layer was lower than that of ck1 and ck2 1 .6 ℃ and 0 .8 ℃, which is very effective in controlling corn vegetative growth, promoting reproductive growth and alleviating the premature decline of conventional maize. The total growth period was 14 days and 6 days longer than that of ck1 and ck2, respectively The increase rate of production reached 2 7.4% and 1 9.7%, and the water production efficiency also increased by 2.25kg / (hm2 · mm) and 1.35kg / (hm2 · mm).
