丘陵旱地发展灌溉的研究

山西临汾地区的丘陵阶地,长期以来干旱缺水、土质脊薄、耕作粗放、产量不稳不高,这部分农田占该地区耕地的40％。为了改变这些地方的农业生产条件,需要发展农田灌溉。本文针对这一问题,经过几年的试验研究,从丘陵旱地发展灌溉的必要性、可行性、灌水技术选择、经济效益等方面进行了综合分析,提出了应以输水管道化和水池调蓄为主,充分利用当地小水源,采用节水型灌溉技术,并实行限额灌溉。

Study NO THE Development OF Irrigation IN THE Hilly Dryland

Owing to shortage of water,draught, poor soil texture and extensive cultivation, the yields in the hilly terrace of Linfeng Area, Shangxi Province have long been neither high nor stable. Hilly terrace covers 40% of the total cultivated lands. Therefore, farm irrigation is urgently required to improve local conditions of agricultural production. According to several years' experiments, the paper makes a comprehensive study on the necessity and feasibility of the development of irrigation in the hilly dryland, on the selection of irrigation technclogies and en cconcmic benefits, the paper also recommends that irrigation primarily aims at pipe supply of water and reservier action. Full use of small local water resources, the application of water-saving irrigation techniques and of limited irrigation are important measures that call for great attention as well.
