| 摘 要： | 目的]为砂田西瓜节水高产提供依据。方法]在种植方式、播种时间、底肥、补水方式和灌水次数均相同的情况下,选用当前补水效果好的滴灌和保水效果好的地膜覆盖结合的方式作对比试验设计,观测蔓长、纵横径、土壤含水率、西瓜需水量和产量的差别。结果]处理2(膜下滴灌株距1.5 m、灌水定额90 m3/hm2)比处理1(株距1.8 m、灌水定额60 m3/hm2)产量提高26.4%。处理2纯收入15 024元/hm2,处理1纯收入11 428.5元/hm2,前者比后者纯收入提高31.5%,但前者灌溉定额增加180 m3/hm2。结论]处理2比处理1生长和效益均好一些。

| Abstract: | Objective] The study aimed to provide the basis for the water saving and high yield of watermelon in sandy field.Method] When the planting modes,sowing time,bottom fertilizer,water supplying mode and irrigation times were all same,the mode of combining the drip irrigation with good water supplying effect and the plastic film mulching with good water conservation effect was selected as the comparative test design to observe the difference on the traits such as vine length,water content in soil,water requir... |
