吐鲁番地区的许多日光温室葡萄,在定植第2年即能获得较高产量,但以后的几年常由于管理不当而出现花序小、果实畸形、产量下降等现象。笔者分析,产生这种现象的原因与种植者对温室这一特殊栽培环境认识不足,对葡萄花芽成因了解不够和栽培管理措施没跟上有关。对此,谈谈解决日光温室葡萄大小年的主要对策,供果农参考。1选用良种由于日光温室这一高温高湿的特殊栽培环境容易造成葡萄徒长,不利于形成花芽,故而在选择品种时除了考虑早熟性好的生长特点外,还要注意选择生长势相对较弱、易形成花芽、耐弱光、耐潮
Many greenhouses in the Turpan region have higher yields in the second year of colonization, but in the later years they often show small inflorescences, fruit malformations and decreased yields in subsequent years. The author analyzes the causes of this phenomenon and the growers lack of understanding of the greenhouse cultivation of this special environment, grape vine budding cause of inadequate understanding and cultivation management practices did not keep up. In this regard, talk about the main measures to solve the year of grapes in the greenhouse, for farmers reference. 1 Selection of seeds As the greenhouse of the high temperature and humidity of the special cultivation environment easily lead to the growth of the grape is not conducive to the formation of flower buds, so in the selection of varieties in addition to consider the good early maturity growth characteristics, but also pay attention to select the growth potential is relatively weak, Easy to form flower buds, resistance to weak light, moisture-resistant
