花生喷水灌溉技术的研究

山东省花生１１００万亩，尚有７０％无灌溉条件。多数地处低山丘陵区，干旱是山东省花生生产的主要制约因素．通过研究明确，亩产２５０－４５０公斤中熟大花生需水量为４８０－８００毫米。经过需水量与亩产等方面相关分析，得出各阶段需水率和需水强度、花生各发育期土壤水分适宜范围，提出花生适宜灌溉方式以移动式喷灌磁化水为好，并提出花生喷灌工程规划设计基本参数。以及提供配套工程及技术要点。

A STUDY ON METHODS OF SPRAYING IRRIGATION FOR GROUNDNUT

Groundnut growing area in Shandong province is over 700000 ha,but 70% of which doesn't possess irrigationg facilities. Drought is a common constraint to groundnut production in this province particularly for that in hilly areas.In this paper,six aspects were studied including: 1)dynamics of water requirement for groundnut growth, 2) appropriate scope of Soil moisture for different growth stages, 3)most desirable irrigating method, 4)parameters for designing irrigation projects for groundnut, 5)key techniques for establishing conveyance systems,and 6)prospects of irrigation techniques for groundnut.
