红壤旱地绿豆种植密度、施肥试验研究

摘要

The effects of different planting densities and fertilization treatments on the grain yield, growth period and main characters of Tongjiang mung bean in Jiangxi provincial upland red soil were studied. The results indicated that: the optimum combination conditions of planting density and fertilization were planting specs 40 cm x25 cm, and fertilizer formula urea 150 kg/hm2 + potassium chloride 150 kg/hm2 + calcium magnesium phosphate 375 kg/hm2; under these conditions, the highest grain yield of mung bean was achieved, reaching 1680.00 kg/hm2.%在江西红壤旱地研究了不同种植密度、施肥处理对桐江绿豆籽粒产量、生育期和主要性状的影响.结果表明:绿豆的最佳密度、肥料组合条件为种植规格40 cm×25 cm,施用尿素150 kg/hm2、氯化钾150 kg/hm2、钙镁磷375 kg/hm2；在此条件下,绿豆的籽粒产量最高,达1680.00 kg/hm2.
