| 摘 要： | 本文通过西瓜微喷试验,,研究了西瓜的需水规律、灌溉制度以及微喷对西瓜产量和含糖度的影响。试验资料表明;微喷西瓜此沟灌增产45％,省水50％左右,西瓜全生育期可喷水3～4次,灌水定额以15～17m~3/亩为宜。适宜土壤含水率为苗期60～70％,伸蔓期60～75％,结瓜期70～80％,成熟期55～65％(占田持百分数)。西瓜全生育期需水强度高峰值在结瓜期,日平均需水量达5.4mm,此期是灌水关键时期。试验表明,微喷西瓜是一种节水节能、效益高、设备简单、使用方便的灌水方法。

| Abstract: | This paper deal with the law of water requirements, irrigation scheduling and variance of yield and sugariness of watermelons through the mini-spray irrigation test. The results of tests show that the yield of watermelons achieves through mini-spray irrigation has increased by 45% in comparison with that achieved through furrow irrigation, And mini-spray irrigation saves half of the water furrow irrigation takes. Watermelons can be sprayed with water three or four times in their growing season. The rated irrigation water amounts to 15-i7m~3/mu. The proper soil water contents are respectively 60-70% at the shoot stage, 60-75% at the spreading stage, 70-80% at the melon-growing stage and 55-65% at the mature stage (soil water capacity is expressed by percentage). The peak water requirements of watermelons are at the melongrowing stage. The daily average amount of water requirments is 5.4mm at this stage. The tests show that mini-spray irrigation for watermelon is a method of saving energy, saving water and high benefit and a method with simple equipment and at easy use. |
