摘要
为不断优化辣椒氮肥适宜用量,设置氮肥总量控制试验,为高产、经济、环保和施肥零增长提供科学依据,试验结果表明,与常规施肥相比,优化施肥增产、增效效果明显,氮肥最佳施肥量为157.5kg/hm^2,结合当地施肥量,建议氮肥用量为204.75kg/hm^2,最大产量为60503.6kg/hm^2。
The amount of nitrogen fertilizer set up to provide scientific basis for high yield, test results showed that compared with conventio was optimized, and the total nitrogen control experiment was economy, environmental protection and zero fertilization, the nal fertilization, optimized fertilization, synergistic effect to in- crease production, nitrogen fertilizer rate is 157.5kg/hm2, combined with the local fertilizer rate, recommended nitrogen dosage is 204. 75kg/hm2 ,the maximum yield of 60503.6kg/hm2.
