西瓜重茬种植后,枯萎病严重,甚至造成绝收,已成为影响我区西瓜生产发展的一大瓶颈。自2005年以来,我们在全区推广西瓜应用嫁接栽培技术,收到了明显效果,平均单瓜重8千克,亩产5928千克,亩增产1482千克,亩增效益741元,重茬种植3～4年,植株仍然不感染枯萎病。一、嫁接技术要点1.砧木选择。砧木品种的选择是西瓜提高嫁接成活率、保证品质、防病增产的关键。实践证明,长瓠瓜是西瓜嫁接的理想砧木。
Watermelon crop after planting, the serious wilt disease, or even caused by the absolute income, has become a major bottleneck affecting the development of watermelon production in our region. Since 2005, we have promoted the application of watermelon grafting cultivation in the region, and have achieved remarkable results. The average weight of single melon is 8 kg, output of 5,928 kg per mu, yield of 1,482 kg per mu, profit increase of 741 yuan per mu, planted for 3-4 years Plants still do not get blight. First, the main points of grafting 1. Rootstock selection. The choice of rootstock varieties is to improve the survival rate of grafted watermelon to ensure quality, disease prevention and increase the key. Practice has proved that long 瓠 melon is an ideal rootstock grafted watermelon.
