近年来,巨峰葡萄栽培面积日益扩大,在栽培中出现了不少问题,现就生产中存在的误区及如何解决谈几点看法,供参考。 一、超负载结果 留枝密、留穗多,每亩产量3000公斤以上,有的甚至高达5000公斤。巨蜂葡萄亩产量超过2500,公斤,品质下降,主要表现果粒小,穗形不整齐、着色差、糖度低、风味淡,同时,超量结果后导致树势早衰,抗病能力下降,如水灌子病、白腐病、炭疽病等爆发流行,大量浆果腐烂、减产,甚至翌年叶片黄化、整株死亡。
In recent years, Kyoho grape cultivation area is expanding, there have been many problems in the cultivation, is now on the production of the errors and how to solve talk about a few comments for reference. First, overloading the results stay sticks dense, stay spike more than 3000 kg per acre, and some even up to 5000 kg. Large bee grape yield of more than 2500 kg, the quality of the decline, the main performance of fruit small, irregular spike shape, poor color, low sugar content, light flavor, while excess results lead to premature aging tree, disease resistance decreased, such as water Outbreaks such as rotting, white rot, and anthracnose were widespread. A large number of berries were decayed and the yield was reduced. Even the leaves were yellowed the following year and the entire plant died.
