商丘市睢阳区种植西瓜已有40年以上的历史,为克服重茬带来的弊端,目前瓜农都采取嫁接栽培技术。嫁接西瓜在生长发育期间,除发生侵(传)染性的病害外,还会发生一些非侵(传)染性的病害。非侵(传)染性病害,又称生理性病害,是由不适宜的环境条件或管理不善引起的导致西瓜植株生理障碍而发生的异常现象。多数西瓜种植户认不清侵染性病害和非侵染性病害,盲目用药,不仅增加了成本,而且防效不佳,降低西瓜的产量和品质,造成损失。现将嫁接西瓜常见生理性病害症状及防治措施介绍如下。
Shangyang City, Shenyang City, planting watermelon more than 40 years of history, in order to overcome the shortcomings brought about by stubble, melon farmers have adopted grafting cultivation techniques. Grafted watermelon during growth and development, in addition to invasive (transmission) of the disease, there will be some non-invasive (transmission) of the disease. Non-invasive (transmission) disease, also known as physiological diseases, is caused by inappropriate environmental conditions or poor management caused by watermelon plant physiological disorders and abnormalities. Most watermelon growers do not recognize infested diseases and non-infectious diseases blindly medication, not only increased costs, but also poor control efficiency, reduce watermelon production and quality, resulting in losses. Grafting watermelon are now common physiological symptoms and prevention measures are described below.
