现在正值西瓜上市的好时节,但是近来各个西瓜种植区的暴雨给不少瓜农心里蒙上了一层阴影,因为西瓜被水淹后,死苗、乱瓜、坏瓜的现象大大减少了瓜农们的收益,此时补救措施成为了关键,那么西瓜淹水后怎么抢救?措施有哪些呢?

01清沟排渍,防止死苗
西瓜平生需水虽多,但极不耐涝,一旦水淹或雨水过多,每每会造成根系缺氧而导致全株窒息灭亡。在雨水多、雨量大的环境下,必需当真疏通“三沟”,出格是阵势低洼,容易积水的田块,更要进一步挖宽挖深“三沟”。
详细作法是:在每条瓜沟双方开竖沟,瓜中间开腰沟,瓜田附近再开围沟。竖沟深30-35厘米,腰沟深40-45厘米,围沟深50-60厘米,做到沟沟相通,雨住田干,从而掩护根系发育和茎蔓健壮生长,搭好丰产苗架。

02人工授粉,确保坐果
西瓜属虫媒异花授粉作物,雨水多的气候会使授粉昆虫勾当削减,因而引起天然授粉不良,难以坐果,必需通过人工辅助授粉以提高西瓜坐果率。可选择好天上午7-10时,阴天上午8-11时,将当天开放散粉的雄花采下,去掉花瓣,然后将雄花的雄蕊瞄准雌花的柱头,轻轻涂几下,看到柱头上有明明的黄色花粉即可,一朵雄花一般可授2-3朵雌花。在阴雨天人工辅助授粉时,应在着花的前一天在雌花上套上防雨筒罩,授粉完毕后再套上。
03抢时喷药,防治病虫害
雨水多的气候,极易诱发枯萎病、疫病、炭疽病以及蚜虫、黄守瓜等多种病虫害。假如防治不实时,每每会造成病虫害大面积风行,从而降低西瓜商品性,引起减产,因此要擅长抓住短暂晴晴天气,实时喷药防治。

04高架固定,“树上种瓜”避二次淹水
在西瓜被淹后不久,可以在西瓜田里迅速搭起适当高的支架,并人工将西瓜藤蔓沿着支架往上搭,在西瓜上套好稳固的网袋,固定在架子的顶端即可。
