精制有机肥对乐都长辣椒生长发育的影响

Effects of Biological Organic Fertilizer on Growth of Long Pepper of 'Ledu'

以青海省地方品种乐都长辣椒为试材,研究精制有机肥对辣椒生长性状和产量的影响。结果表明:精制有机肥能显著提高产量,增强植株长势,但对辣椒的生育期以及对辣椒的株高、节间长、果实纵径、果实横径、单果重影响不大。辣椒产量的提高主要表现在单株结果数增加,1hm2施用精制有机肥2 100、2 550、3 000kg,辣椒产量依次增加3.07%、6.32%、11.07%,增产效果明显。综合考虑乐都长辣椒生长、产量和经济效益等因素,最佳施肥量为3 000kg/hm2。

Taking long pepper varity of ＇Ledu＇ as material,the effect of different biological organic fertilizer amount on its growth and yields were studied.The results showed that the biological organic fertilizer could significantly raise the yield,promote growth vigour,increase pepper number per plant,but it had small effect on the growth periods,and its plant hight,internode length,longitudinal diameter,transverse diameter and single pepper weight.The effect of the biological organic fertilizer was on the long pepper of ＇Ledu＇ yields increasing chiefly depended on promoting the pepper,s number per plant.The yields of the pepper were increased 3.07%,6.32%,11.07% with the biological organic fertilizer 2 100 kg/hm2,2 550 kg/hm2,3 000 kg/hm2,and yield increased were obviously.Organic fertilizer 3 000 kg/hm2 was the suitable for the long pepper varity of ＇Ledu＇,which will bring optimal yield and economic income of the long pepper varity of ＇Ledu＇.
