摘要
通过选取不同的补灌技术对压砂地西瓜进行了补水技术研究,结果表明:补灌技术对西瓜纵径和西瓜横径具有相同的影响效果,西瓜成熟后车补、滴灌、管灌处理的西瓜纵径分别为27.7、29.2、25.8cm,西瓜横径分别为19.4cm、20.7cm、18.9cm,滴灌西瓜横径最大,车补次之,管灌最小。三因素三水平的最优组合为滴灌方式、灌水定额为90m3/hm2,灌水次数为5次;经方差分析可知,灌水定额和补水方式对产量影响显著,灌水定额较之补水方式更为显著,而灌水次数无显著影响。
The paper researched the water-saving supplementary irrigation of watermelon in gravel-mulched field by choose different supplementary irrigation technology,the result indicates that the supplementary irrigation technologies have the same impact effect to vertical and crosswise diameter of watermelon.The vertical diameter of the ripe watermelon is 27.7,29.2,25.8 cm,respectively,for tractor irrigation,drip irrigation and tube irrigation,and the crosswise diameter is 19.4,20.7,18.9 cm respectively,for tractor irrigation,drip irrigation and tube irrigation.The best combination of three elements and three levels is drip irrigation,the irrigation quota is 90m3/hm2,the frequency of irrigation is 5.The result of analysis of variance indicates that the irrigation quota and supplementary way have conspicuous effects and the former is more,but the frequency of irrigation has no conspicuous effect.
