| 摘 要： | 为探讨控释肥对辣椒生产的提质增效作用,进一步实施化肥减量增效和轻简化栽培,采用蔬菜专用控释肥在辣椒上进行梯度用量比较试验,42%控释肥用量设5个处理,667 m~2用量分别为80、90、100、110、120 kg,以常规施肥为对照,研究适宜辣椒生产的最佳控释肥用量。结果表明:667 m~2施用42%控释肥120 kg的处理5最优,667 m~2较对照减施纯养分13.1 kg,减量19.4%,667 m~2增产427 kg,增产率29.9%,667 m~2净收入提高1 960元,净增收提高37.5%,为化肥减量增效提供了一种选择。

| Abstract: | In order to explore the improving quality and efficiency effect on pepper production with controlled-release fertilizers, and implement chemical fertilizer reduction with efficiency increasing and simplified cultivation, the gradient dosage of controlled-release fertilizer was compared on pepper. The amount of 42% controlled-release fertilizer was used to set 5 treatments, such as 80, 90, 100, 110 and 120 kg per 667 m2, respectively. The optimum amount of controlled-release fertilizer in pepper production was studied by using conventional fertilizer as control. The results showed that treatment 5 with 42% controlledrelease fertilizer applied 120 kg per 667 m2 was optimal, compered with control, the pure nutrient reduced by 13.1 kg per 667 m2 with total application reducted by 19.4%. The yield increased by 427 kg per 667 m2 with increase rate of 29.9%, the net income increased by 1 960 yuan per 667 m2 with increase rate of 37.5%. It provided a choice for fertilizer reduction with effici ency increasing. |
