随着保护地黄瓜的发展,黄瓜枯萎病和黄瓜疫病有加重趋势,成为生产上的一大难题。这两种病害俗称死秧或死藤,是一种土传病害。枯萎病菌是从根部侵染的导管性病,疫病菌则借流水多从茎基部侵染。嫁接黄瓜是利用南瓜地对两种病具有高度抗性这一特性进行防治。同时,嫁接砧木云南黑籽南瓜具有耐低温,根系发达,生长势强的特性,故嫁接黄瓜结瓜早、瓜条多、产量高。 我国在80年代初已开始推广黄瓜嫁接技术。但发展较慢,主要原因是嫁接费工,还需要嫁接夹子或其他固定物,如果方法不当,成苗率往往较低。为了解决
With the development of cucumber cucumber, cucumber wilt disease and cucumber disease have aggravating trend, becoming a major problem in production. These two diseases commonly known as dead seedlings or dead vine, is a soil-borne disease. Fusarium oxysporum is a ductal disease that infects from the root, and the blight bacteria invade through the base of the stem by flowing water. Grafted cucumber is the use of pumpkin to the two diseases have a high degree of resistance to prevent this characteristic. At the same time, grafted rootstock Yunnan black seed pumpkin has the characteristics of low temperature resistance, developed root system, strong growth potential, so early grafting cucumber, melon and more yield. In the early 1980s, China began to promote the technology of cucumber grafting. However, the slow development is mainly due to grafting, but also requires grafting of clips or other fixtures. If improper methods are used, the rate of emergence is often low. In order to solve
