石灰氮处理葡萄结果母枝,有促进ABA降解的作用,在一定程度上可代替低温的生物学效应提早解除葡萄休眠。营口地区南部有葡萄设施栽培1000hm2,其中,温室栽培‘晚红’面积占80%以上。为了提早温室升温,抢占鲜果市场,果农大都在12月上旬开始揭苫升温,并普遍使用石灰氮打破休眠。由于使用浓度不当造成效果不佳和药害反应发生。为此,笔者设计了浓度比较试验。 Lime-nitrogen treatment of grapes with fruit branches can promote the degradation of ABA, to a certain extent, it can replace the biological effects of low temperature to lift the grape dormancy earlier. There are 1000hm2 grape cultivation facilities in the south of Yingkou, of which, the area of ​​’late red’ in greenhouse cultivation accounts for more than 80%. In order to warm up the greenhouse early and seize the fresh fruit market, most farmers started to expose and heat up in early December and commonly used lime nitrogen to break dormancy. Due to the use of improper concentration caused by ineffective and phytotoxic reactions. To this end, I designed a concentration comparison test.
