寡日照地区不同水肥管理对设施番茄生长、产量及经济效益的影响

Effect of Different Water and Fertilizer Management on Growth,Yield and Economic Benefit of Greenhouse Tomato in Weak Daylight Area

以番茄为试材,研究了不同水肥管理对设施番茄生长、产量及经济效益的影响。结果表明:水肥一体化在提高番茄产量、节水、节肥、省工方面优势明显。番茄的产量得到保障和增加,增产16.22%;水分利用率提高了33.21%,节水率为21.89%,节省用肥39.50%,省工达12.20%;滴灌施肥比漫灌施肥明显降低大棚内的空气湿度;降低病虫害的发生,滴灌施肥农药用量减少21.05%。

Taking tomato as test material,the effects of different water and fertilizer management on tomato growth,yield and economic benefit of the facilities were studied.The results showed that the integration of water and fertilizer had obvious advantages in improving tomato yield,water,fertilizer and labor aspects.The yield of tomato was guaranteed and increased,the yield increased by 16.22%.Water use efficiency increased by 33.21%,water saving rate of 21.89%;saved up to 39.50% with fertilizer;labor-saving was 12.20%.Drip fertilization significantly decreased the air humidity in the greenhouse than irrigation fertilization.It was to reduce the occurrence of pests and diseases.Drip fertilization and pesticide dosage the pesticide dosage of drip fertilization decreased by 21.05%.
