西瓜枯萎病又称为慢割病、萎蔫病,属于真菌性病害,该种疾病对西瓜的危害十分严重,轻度发病会严重影响到西瓜植株生长,导致植株矮小、生长发育不良、黄化、结实率下降,果实变小,严重的会导致西瓜严重减产甚至绝收。最近几年,江苏省宝应县西瓜种植面积逐年增加,当地西瓜枯萎病的发生和危害日趋严重。农民群众在防治西瓜枯萎病过程中缺乏科学防治意识,药物防治存在的不合理地方,常常因为防治不及时,错过最佳防治时间,给种植户造成严重的经济损失。基于此就需要我们积极探索一套西瓜枯萎病绿色防控配套技术,提高防治效果,避免损失进一步扩大。本文主要结合实际情况,就西瓜枯萎病的发生和绿色防控技术进行了分析,希望通过本次研究对同行有一定帮助。
Watermelon Fusarium wilt disease, also known as slow cutting disease, wilt disease, belongs to fungal diseases, the disease on the watermelon is very serious harm, mild disease will seriously affect the watermelon plant growth, leading to short plants, poor growth and development, yellowing, Seeds fell, the fruit becomes smaller, serious watermelon can lead to serious or even cut. In recent years, the planting area of watermelon in Baoying County of Jiangsu Province has been increasing year by year. The incidence and harm of watermelon wilt in the local area have become increasingly serious. Farmers in the prevention and control of watermelon Fusarium wilt disease of the lack of awareness of scientific control, drug control exists in an unreasonable place, often because of prevention and treatment is not timely, missed the best time to prevent and control, causing serious economic losses to growers. Based on this we need to actively explore a watermelon wilt disease prevention and control of green matching technology to improve prevention and treatment to prevent further loss of expansion. Based on the actual situation, this paper analyzed the occurrence of watermelon wilt and green prevention and control technology, hoping to help the peer through this study.
