摘要: 针对沙漠沿线,沙地分布广,面积大,利用率低,干旱缺水,农作物产量不高等实际情况,从节水,增收和提高土地利用率角度考虑,在沙地上,揭去表层40 cm土层后,整平表面,铺设棚膜,然后覆土整平,种植作物,进行不同灌水量(次数)试验。本试验选籽瓜作参试作物,结果是设置棚膜保水隔层的三个处理节水16.7%~50%,增产11.8%~18.5%,经济效益相对增加380~1018元·hm-2。其中处理Ⅱ,即灌水量为3428 m3·hm-2的处理,节水33.3%,增产377 kg·hm-2,效益相对CK增加1018元·hm-2,是最优选择结果,值得借鉴和推广。

Abstract: On the vast sandy land area of China the crop yields are low due to water shortage. A water-saving experiment was conducted for the purposes of increasing crop yield and improving land use efficient. On the leveled land surface with 40cm depth of crust soil having been moved away, firstly, thick plastic film was mulched; secondly, soil was return to cover the film evenly; lastly, seed-melon were cultivated. The experiment with 3 treatments of irrigating times showed that it can save 16.7%~50% water, increase 11.8%~18.5% crop yield and increase 380~1 018 yuan·hm-2 (RMB) economic effectiveness. The No.2 treatment with 3 428 m 3·hm-2 irrigation quota as the optimal result (saving water 33.3%, increasing yield 377 kg·hm-2, and increasing economic effectiveness 1 018 yuan·hm-2 (RMB) is worthy of being extended.
