黄瓜枯萎病是北方保护地黄瓜主要病害之一。该病由土壤传染,引起整株枯死,连茬种植多年后,一般发病率在20～30％,严重地块可达70～80％,甚至绝产。几年来,我所进行了砧木选择、嫁接组合、嫁接技术等研究,肯定了云南产的黑籽南瓜为优良砧木,证实了嫁接黄瓜防病增产效果,研究出工效快、成本低、成活率高的嫁接新方法。筛选出几个较好的嫁接组合:如农大14、长春密刺、山东密刺与黑籽南瓜嫁接表现抗病性强、耐低温、根系发达、长势繁茂、增产显著、瓜条品质优良。目前在京、津地区有较大面积推广,深受菜农欢迎。现将黄瓜嫁接新方法及其苗期管理技术介绍如下: 一、黄瓜嫁接新技术常用靠接法、胚轴插接法、水平插接法、劈接法、双叶插接法、
Cucumber Fusarium wilt is one of the main cucumber diseases in northern protected area. The disease is caused by soil infection, causing the whole plant to die. Even after planting for many years, the general incidence rate is between 20% and 30%, and the severe land can reach 70% to 80%. Over the past few years, I conducted a study of rootstock selection, grafting combinations, grafting technology, affirmed the black seed pumpkin produced in Yunnan as an excellent rootstock, confirmed the curative effect of grafted cucumber disease prevention, research work efficiency, low cost, high survival rate The new method of grafting. Several good grafting combinations were screened out: such as Nongda 14, Changchun stichopus, Shandong stichopus japonicus and black seed pumpkin grafted showed strong disease resistance, low temperature resistance, developed roots, lush growth, significant yield increase, good quality of the melon. Currently in Beijing, Tianjin area has a larger area to promote, welcomed by vegetable farmers. Now the new method of cucumber grafting and its seedling management techniques are as follows: First, the new technology of grafting Cucumber commonly used docking method, hypocotyl plug-in method, the level of plug-in method, cleavage method, double leaf plug method,
