摘要
在吉林省中部黑土区菜园地上,研究了氮磷复合粒肥不同用量对茄子生长发育及产量的影响,筛选出氮磷复合粒肥最佳经济用量。结果表明:茄子氮磷复合粒肥最佳经济用量为918kg/hm2,对应最佳经济施肥量的产量为298338kg/hm2,其产投比为41;同时获得了植株。
The optimum dose was selected by studying the effect of N and P compound fertilizer and its different dose on egg apple growth,yield and plant nutrient by field cultivation. The result showed that the optimum economic dose is 918 kg/hm 2,and in this condition,the yield of egg apple is 29833.8 kg/hm 2.
