| 摘 要： | 针对陇东旱作农业区年降水量少、季节分布不均,特别是玉米生产中干旱和苗期低温等问题,从改善旱地玉米生长环境和栽培条件、提高降水利用率入手,将小垄沟集水和覆膜增温保墒技术有机地结合在一起,进行了旱地玉米垄沟周年覆膜栽培新模式试验研究。结果使旱地玉米水热条件明显改善,增产效果显著,是陇东旱地玉米自然降水高效利用,实现高产稳产的最佳栽培方式。

| Abstract: | Aimed at the situation of limited and unevenly distributed rainfall in Longdong dryland area,especially the problem of drought and low temperature during the growing period of corn,the experiment was conducted to evaluate the effects of furrow catchment and plastic mulching on the growing environment of corn and the use efficiency of rainfall.The results indicated that the mode of whole-year film-mulch cultivation could improve the moisture and heat condition of soil and increase the yield of corn in dryland.Therefore,it was the ideal cultivation mode to increase the use efficiency of rainfall and to realize high and steady yield in Longdong dryland. |
