水分是花生获得高产的重要条件。但自然降雨与花生不同生育阶段需水常发生矛盾,表现为年际间不同生育阶段时有旱象出现,对花生生长和荚果发育影响很大。七十年代以来花生主产国对花生需水规律和灌溉技术已有较深入研究。目前定型的成套喷灌机具已在大面积生产上应用,对保证产量持续上升起到了积极的作用;国内对花生需水规律和溉溉等方面也有 Moisture is an important condition for high yield of peanuts. However, there is often a contradiction between natural rainfall and water requirement of peanut at different stages of growth, which is manifested as the emergence of drought at different stages of growth during inter-annual period, which greatly affects peanut growth and pod development. Since the 1970s peanut main producing countries of peanut water requirements and irrigation techniques have been more in-depth study. The current set of complete sets of irrigation equipment has been applied in large-scale production, to ensure the continued rise in production has played a positive role; the domestic law of peanut water and irrigation, etc. also have
