采用一般方法结合地膜覆盖技术,进行大田葡萄育苗,出圃率可达60.87％。现将此方法简介如下: 一、圃地选择。选择地势平坦肥沃的中壤土,施基肥浇大水后耕翻做畦,畦呈南北向,宽1米,长不限,畦数可根据插条量确定。二、插条处理。把贮存过的插条取出,选择节间较短,第一芽饱满的进行复剪,上端剪成平口,距第一节位1厘米,末端剪去未节1/3,在节芽异侧剪成45度角;一般插条剪留三芽,要求长度一致。插条每50根一捆,依次放入5cm深的清水中浸泡“根节”部12小时,然后再放入40ppm荼乙酸溶液中浸泡6小时,然后立即扦插。三、扦播方法。按株行距10×20cm开沟逐条扦插,深度控制在12cm左右,南北
Using the general method combined with plastic film mulching technology, the field grape seedlings, the rate of up to 60.87%. Now this method is as follows: First, nursery choice. Select the flat and fertile terra lobed soil, Shi fertilize the water after fertilization turned 畦, 畦 was north-south, 1 m wide, long not limited, the number of 畦 can be determined according to the amount of cuttings. Second, cuttings deal. The stored cuttings removed, select the internodes shorter, the first full buds for complex scissors, the top cut into the mouth, 1 cm away from the first section, the end cut off the section 1/3, Cut into 45-degree angle; cuttings generally cut three buds, requiring the same length. Cuttings for each 50, followed by immersion in 5cm deep water, “root section” for 12 hours, then add 40ppm tea solution soak for 6 hours, and then cuttings. Third, cuttage method. According to the spacing of 10 × 20cm row ditches by cutting, the depth of control in about 12cm, north and south
