旱地玉米优化栽培措施探讨

Probe into the Improving Measurement in Dry Land Maize Cultivation

采取平作、沟垄种植、沟垄加垄上覆盖秸秆、沟垄加垄上覆盖地膜、沟垄加全秸秆覆盖等措施 ,并配合以不同耕地方式 ,探讨旱地玉米综合栽培技术。试验结果以机械深耕、沟垄种植、垄上覆盖地膜相结合产量最高 ,达 32 10kg/hm2 ,降水利用率最高 ,为 9.75kg/hm2 。

Integrated cultivation techniques in dry land maize production were studied by way of different farm work such as conventional planting, ridge culture, ridge culture with straw mulching, ridge culture with plastic mulching, and ridge culture with whole straw mulching etc. Experiment results showed that the combination of deep plough with machine and ridge culture with plastic film mulching on the ridge gave the best results of 3 210kg/hm 2 of yield and 9.75kg/hm 2 of precipitation utilization.
