近年来,随着城市近郊菜区钢筋大棚、塑料管棚和玻璃温室的不断发展,保护地设施内的连作障害逐年加重。为了提高单位面积的产量,解决连作障害的问题, 我站自1982年下半年起,参考国外同类产品,仿制了塑料园艺嫁接夹。经过两年多在生产上的试用,效果较好。现将有关嫁接技术简介如下。靠接是瓜类嫁接中最常用的方法之一。靠接后的嫁接苗,在一定的时间内,因同时留其砧木和接穗的根,所以最安全可靠,成活率最高。 (一)嫁接的目的:主要是利用砧木的根 In recent years, along with the continuous development of reinforced greenhouses, plastic pipe sheds and glass greenhouses in urban vegetable suburb areas, continuous cropping obstacles in protected land facilities have been increasing year by year. In order to improve the yield per unit area and solve the problem of contingency, I stood in the second half of 1982 with reference to similar foreign products and imitated the plastic gardening grafting clamp. After more than two years of trial production, the effect is better. Now the grafting technology is as follows. Docking is one of the most commonly used methods of melon grafting. Graft after abutting the graft, in a certain period of time, because at the same time leaving the rootstock and scion roots, so the most secure and reliable, the highest survival rate. (A) the purpose of grafting: The main rootstock is the use of rootstocks
