醋栗的病虫害防治

植物图片 2021-03-15 10:41

醋栗，在我们的北方地区和南方地区基本上都有种植，但是一般在黑龙江省和吉林省比较的多。它的株高一般有1.3米左右，一般一个株丛可以发出50多个枝。它的果子是有点接近圆形的，大约有1厘米左右大，是黄绿色的，味道比较酸，种子比较的小，比较适合用来进行生吃或者加工后食用。但是当它生病有虫子伤害了后该怎么防治呢，我们一起来看看吧。

1.利用修剪防治

当醋栗生病的时候，我们可以挑选一些好的枝条留下，然后将它一些生病的、有虫子咬的，还有一些老的残枝，用专业的树剪把他们给剪掉。当然不要以为只要将他们剪掉就行了，我们还要对他们进行彻底的销毁。

我们把剪下来的被伤害过的枝条在把它们集中起来，进行集体的烧毁，这样就把它的发病源彻底销毁，所以用这种方法，可以从根源上解决残枝带来的病虫害。

2.用化学药剂进行防治

一般醋栗的主要病虫防害生的病为白粉病和透翅蛾。白粉病主要对叶子的伤害比较大。发病期的表现是，在叶的表面或者它的背面有白色物质，像细小的粉面。然后渐渐的由白色再变成黑褐色。再后来，上面就全是黑色的小颗粒，而且还会渐渐的蔓延到叶柄、果柄和枝条的位置上。

所以这就提醒我们，一定要合理的密植，不能够靠的太近，保证充足的阳光的照射。然后如果实在发病的初期的话，我们就可以采用一些化学药品进行调配稀释，然后对它进行喷洒，一般常用的药物就是马拉硫磷对它进行2000倍或者3000倍液进行喷洒，可以连续的喷洒个2到3次。

透翅蛾一般都是幼虫来伤害醋栗果的枝条、芽和叶子，然后会让叶子慢慢干枯落下，所以对于这种害虫也可以用上面的这个药物进行喷洒，也对它进行连续2到3次的喷洒，这样就可以很好的对害虫进行有效的防治。所以这两种方法都是对虫子防治的比较好的方法。
