| 摘 要： | 通过试验,研究了不同膜宽对老压砂地西瓜产量的影响,结果表明,覆膜宽度1.4m、灌水定额60m3/hm2的处理比覆膜宽度0.8m、灌水定额60m3/hm2的处理产量提高42.56%;覆膜宽度1.4m、灌水定额60m3/hm2的处理纯收入为10378.8元/hm2,覆膜宽度0.8m、灌水定额60m3/hm2的处理纯收入为7280.1元/hm2,前者比后者增收3099元/hm2。

| Abstract: | The paper researched on watermelon yield affected by film width in the old gravel-mulched field and the result showed that the yield improved 42.56% when film width is 1.4 m and irrigating quota is 60 m3/hm2 than film width 0.8 m and irrigating quota 60 m3/hm2. The net income was 10 378.8 Chinese yuan/hm2. The formal increased 7 280.1 Chinese yuan/hm2 than the latter. |
