为了对苹果幼树枝条开张角度,我们曾用过多种方法,如夏秋季在枝条上吊盛水瓶、吊土块、吊石块等。这些方法对枝条开角的效果虽好,但在当地取材比较困难,费事费工.于是,我们在枝条上改用吊塑料袋装土和吊塑料袋装药土的办法。结果表明,在枝条上吊塑料袋装药土的效果更好。它具有枝条开角和防虫的双重效果,而且容易取材,便于实施。具体做法是,用1 kg8o％敌敌畏乳油边倒边搅拌到200 kg细砂土中配成药土,将药土装入1-2层大小不同的新旧塑料袋中,用绳捆好,根据枝条的承受能力,将其吊在枝条的适当部位,使枝条开张到所需的角度,待枝条角度固定后,即可将其取下。此法可
In order to open the apple tree branches angle, we have used a variety of methods, such as summer and fall hanging in the branches Sheng bottles, hanging blocks, hanging stones and so on. These methods have good effect on the opening angle of the branches, but it is more difficult and costly to make the materials locally, so we use hanging plastic bags and hang plastic bags to fill the soil on the branches. The results show that the effect of hanging plastic bags on the branches is better. It has the double effect of open angle and pest control, and easy to draw, easy to implement. Specifically, with 1 kg8o% dichlorvos EC side down while stirring to 200 kg of fine sand mixed dough, the soil into the 1-2 layers of different sizes of old and new plastic bags, tied with a rope, according to the branches To withstand capacity, hang it in the appropriate parts of the branches, so that branches opened to the desired angle, until the angle of the branches fixed, you can remove it. This method can be
