茄子氮磷复合粒肥最佳施用量的初步研究

Study on Optimum Dose of Nitrogen and Phosphorus Compound Fertilizer in Egg Apple

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２９８３３８ｋｇ／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.
