一、温度管理1、苗期管理。定植后5—7天内,以保温为主。白天保证在20—25℃,最高28℃,夜间12—15℃。温度超过35℃,应适当放风。2、结果期管理。白天温度应控制在20—25℃,夜间15℃左右。低于15℃易引起落花落果,气温高于30℃会影响养分积累。二、水肥管理在第一穗果实直径3厘米时,植株由营养生长逐渐转变为生殖生长。此时选晴天的上午,浇催果水并施肥。一般追施尿素15公斤/亩,硫酸
First, temperature management 1, seedling management. Within 5-7 days after colonization, the main insulation. Daytime guaranteed at 20-25 ℃, up to 28 ℃, night 12-15 ℃. Temperatures above 35 ℃, should be properly bleed. 2, the results of the management. Daytime temperature should be controlled at 20-25 ℃, 15 ℃ at night. Below 15 ℃ easy to cause drop flowers, the temperature above 30 ℃ will affect nutrient accumulation. Second, water and fertilizer management In the first ear diameter of 3 cm fruit, the plant gradually transformed from vegetative growth to reproductive growth. At this point the election sunny morning, pouring fruit water and fertilizer. General topdressing urea 15 kg / acre, sulfuric acid
