| 为了研究水肥耦合一体化对设施番瓜生长的影响，试验进行了滴灌施肥与叶面喷肥相结合的模式探索。结果表明：设施番瓜灌溉量为4260m3/hm2，滴施氮磷钾平衡型大量元素水溶性肥料（20-20-20）255kg/hm2，叶面喷施水溶肥1000倍液6次（苗期喷施1次，开花期喷施2次，结果采收期喷施3次，每次喷施21kg/hm2），可明显改善番瓜植株农艺性状和商品性能，折合产量可达74227.3kg/hm2，较常规滴施磷酸二铵（345kg/hm2）增产20500.0kg/hm2，增产率38.16%。 |

| Abstract: The effect of water and fertilizer coupling on the growth of facility muskmelon was observed in Lanzhou. The combination of drip irrigation and foliar spraying was adopted in the experiment. The results showed that when the irrigation amount of protected muskmelon was 4 260 m3/hm2, the application amount of nitrogen, phosphorus and potassium balanced water-soluble fertilizer (20-20-20) was 255 kg/hm2 with drip irrigation and spraying water-soluble fertilizer 1 000 times liquid reached 6 times (1 time at seedling stage, 2 times at flowering stage, 3 times at harvest stage, 21 kg/hm2 at each time) , the agronomic characteristics and commercial performance of muskmelon could be significantly improved. The equivalent yield could reach 74 227.3 kg/hm2, which was 20 500.0 kg/hm2 and 38.16% higher than that of applying diammonium phosphate (345 kg/hm2). |
