打底杈和施用沼液肥对辣椒生长发育及产量的影响

Effects of Bifurcation and Biogas Slurry Fertilizer on Growth and Yield of Chili

以羊角椒卡宴为试验材料,以追施复合肥为对照(CK),设追施复合肥+叶面喷施沼液肥(T1)、根施沼渣肥+叶面喷施沼液肥(T2)2个处理,各处理植株分别设打底杈和不打底杈2种整枝方式,测定和分析了不同施肥处理和整枝方式对辣椒农艺性状及产量的影响。结果表明,打底杈处理的植株高度、开展度、分枝数等农艺性状显著优于不打底杈处理,打底杈的处理T1沼液叶面肥与化肥配合施用辣椒株高、开展度等农艺性状指标最为明显,处理T2沼液叶面肥与沼渣肥配合施用在果实横径、纵径、单果重等果实品质上显著优于CK。说明对辣椒进行打底杈处理可以提高辣椒的农艺性状、果实品质以及产量。

The experiment was carried out with horn chill'cayenne'as the test material to determine and analyze the effects of different fertilization treatments and pruning methods on the agronomic characters and yield of chill.In the experiment,topdressing compound fertilizer was applied as the control(CK),and 2 treatments were set,i.e.,topdressing compound fertilizer+foliar spraying biogas slurry fertilizer(T1),topdressing biogas residue fertilizer+foliar spraying biogas slurry fertilizer(T2).Two pruning ways were provided for each fertilization treatment,namely removing the bottom branches and not removing the bottom branches.The results showed that the agronomic characters such as plant height,development degree and branches number of the plants removed the bottom branches were significantly better than those of the plants not removed the bottom branches.The agronomic traits such as plant height and degree of development of T1 chill were most significantly improved when the bottom branches was removed,and the fruit qualities such as horizontal and vertical longitude and single fruit weight of T2 were significantly better than those of CK.It showed that the agronomic characters,fruit quality and yield of chill could be improved by removing the bottom branches of chill.
