Spring clearance is the most important time

If the orchard is cleaned up, most of the pathogens and eggs will be overwintered in the fallen leaves, diseased fruits and dead fruits. It is very important to clean these things out of the orchard.

Spraying should be fine. There is no leaf in the spring clearing garden. Most of the fruit growers have very little water, and most of them are sprayed. In fact, if you want to spray the medicine finely on rough skin, cracks, branches, etc., the water consumption per mu should be no less than 250-300 kg. Otherwise, pests will be difficult to remove in places where they are not sprayed. Linyi Fertilizer Network Copyright
Most of the fruit farmers on the underground trees only pay attention to spraying on the trees, and few people pay attention to spraying the ground. It is necessary to know that the topsoil is a wintering place for many pests and diseases, and they will come out on the trees after the low temperature rises. Therefore, the ground is also the focus of the Qingyuan. If the ground is not sprayed on the direct spray tree, more pests and diseases will become the "fish of the net."
