摘要
通过对春棚西瓜利用浅层地下微咸水膜下滴灌及覆膜畦灌的对比试验 ,结果表明 :3g/ L微咸水膜下滴灌比覆膜畦灌节水 6 7.7% ,增产 30 .7% ,每立方米水产量提高了 18.2 7kg,棚内温度升高 1.1℃左右 ,早上市 16 d左右 ,西瓜含糖量增加了 9.73% ,增收 12 0 15元 / hm2 。试验期间 0～ 6 0 cm土层盐分含量低于 0 .2 % ,不会对西瓜生长构成威胁。
A Field experiment was conducted to study the effects of 3.0 g/L brackish water on watermelon in greenhouses under drip irrigation and furrow irrigation. The result shows that: compared treatments with furrow irrigation under plastic film, water application is reduced about 67.7%, yield increased about 30.7%, yield of per cubic meter water consumption increased 18.27 kg, temperature inside the greenhouse raised 1.1 ℃, sugar content of watermelon products increased 9.73%, matured date moved up 16 days, economic return increased 12015 Yuan/hm 2 in treatments with drip irrigation under plastic film. Salt content in soil layer of 0～60 cm was less than 0.2% and watermelon growth was not affected by salts accumulation during experimental period.
