摘  要：
以黄瓜为试材,采用小区试验对比的方法,研究了滴灌和畦灌条件下不同磷素用量对秋季大棚黄瓜产量的影响,以期为提高秋季大棚黄瓜产量提供参考依据。结果表明:滴灌大棚的黄瓜生长状况明显好于畦灌大棚,商品黄瓜产量显著提高(P<0.05),各阶段用水总量278.3 mm,节水达41%。畦灌条件下,不施磷肥处理黄瓜果实产量显著低于磷肥处理(P<0.05);滴灌条件下,过量的磷肥施用(P2O5100 kg·hm~(-2))导致黄瓜果实产量和品质显著下降(P<0.05)。由此可见,滴灌条件下合理施用磷肥能够降低水资源消耗,提高磷肥利用效率,有利于黄瓜品质和产量的提升。

摘  要：
Cucumber was used as the test material,the effect of P application rates and irrigation regime on cucumber yield in plastic greenhouse was studied by using the method of experiment comparison,in order to provide a reference for raising cucumber yield. The results showed that the marketable cucumber yield of drip irrigation was also higher than furrow irrigation. Total water using in drip irrigation was 278. 3 mm,and the water-saving percentage was 41%. In furrow irrigation,cucumber yield was higher in P application treatments than that in none P fertilizer application. In drip irrigation,the overdose of P fertilizer( P2 O5100 kg·hm~(-2))decreased the cucumber yield,especially for the marketable cucumber. In conclusion,reasonable P application rates in drip irrigation could reduce water resources consumption and increase the P efficiency and cucumber yield.
