摘要
以2种不同类型的生菜品种为试材,研究了尿素和三元复合肥配施对生菜生长指标及经济效益的影响。试验结果表明,对于2种生菜品种,施加不同配比肥料均能不同程度地提高其单株净质量、株高、开展度、叶片大小以及叶片数等生长指标,其中混施尿素和三元复合肥的施肥方式增产效果和经济效益最显著,而施加尿素2.5 kg/667 m^2+三元复合肥2.5 kg/667 m^2与施加尿素5 kg/667 m^2+三元复合肥5 kg/667 m^2的效果差异不大。因此,生菜种植过程中可选择尿素2.5 kg/667 m^2+三元复合肥2.5 kg/667 m^2追施2次作为最佳施肥方式。
Using two different types of lettuce cultivars as test materials,the effects of different fertilizer ratios of urea and three-nutrient compound fertilizer on the growth indexes and economic benefit of lettuce were studied.The results showed that different fertilizer ratios could increase the growth indexes of net weight of single plant,plant height,development degree,leaf size and leaves number for two kinds of lettuce.Among them,the yield and economic benefit of the treatments mixed allocation of urea and three-nutrient compound fertilizer were the most significant.However,the effects of the two treatments 2.5 kg/667 m^2urea+2.5 kg/667 m^2three-nutrient compound fertilizer and 5 kg/667 m^2urea+5 kg/667 m^2three-nutrient compound fertilizer were not significant.Therefore,the ratio of 2.5 kg/667 m^2urea+2.5 kg/667 m^2three-nutrient compound fertilizer was selected for using two times as the best fertilization method in lettuce planting.
