持续春旱使旱作农业区不能如期播种 ,给农业生产造成重大损失。经对旱地玉米不同种植方式抗旱效果分析 ,玉米座水点种加覆膜是旱作区最经济、有效的抗旱播种方式 ;春旱持续时间短 (5月中下旬落接墒雨 ) ,育苗移栽和座水点种可作为抗旱播种方式之一推广应用 ;穴播座水覆膜栽培可作为辅助抗旱措施推广应用 ;春旱持续时间长 ,杜绝种植玉米等生育期长的作物。
Continued spring drought will prevent dry farming areas from sowing as scheduled, causing heavy losses to agricultural production. Through analyzing the drought-resistant effect of different planting ways of maize in dryland, the watermelon planting and plastic filming of corn seat is the most economical and effective method of drought-resistant sowing in dryland area. The duration of spring drought is short (rainwater fall in middle and late May) Planting and seeding spots can be used as one of the planting ways for drought relief. Water-seeding cultivation of seeding spots can be used as auxiliary drought-relief measures. Spring droughts last a long time and cropping crops with long growing periods such as corn are not to be planted.
