摘要
针对土质砂、土层薄和肥力低的条件，在花生地膜覆盖栽培基础上，进行了花生膜上灌试验研究，取得了明显的节水增产效果。与常规的垅沟灌比，节水２７．３％，水分生产率提高７６．９％，提高土地利用率１６．７％，增产３４％～６８．５％。对其节水增产机理在文中作了探讨。
Under the condition of the thin soil layer and low fertility in sandy soil, the experimental research has been done using irrigation on plastic film cover on peanuts cultivation. A distinct good result on water saving and yield increasing was achieved compared with the normal furrow irrigation. It saves water by 27.3 %, improves water productivity by 76.9 %, improves soil utilization ratio by 16.7%, and increases yield by 34 %￣68.5 %. This research also made deep discussion on its mechanism of saving water and increasing yield.
