In recent years, the orchard's deciduous disease, rot disease, red spot disease, black spot disease, and Kang's mealworms, mites and leaf miners have shown an increasing trend. There are many reasons for this, but the unscientific clearing of the garden in spring is one of the important reasons.
Orchard cleaning must be done carefully. Most germs and worm eggs overwinter in stubble and diseased fruits and dead fruit. It is important to clear these things out of the orchard. But there are very few people who can earnestly clean the orchard ground.
Clearing the garden in spring can effectively prevent and kill overwintering pests and diseases, reduce the number of occurrences of pests and diseases, supplement tree nutrition, and promote budding, flowering, and fruiting. The purpose of clearing the garden in spring is to eliminate winter germs and pests. The most important method is spraying. However, the breeding of germs in spring and the emergence of pests are affected by the temperature. After the startle, the temperature is stable above 18 ° C, which is the best time to use the medicine. The temperature is low, there is no activity of diseases and insect pests, the medicinal properties are difficult to play a role, and the control effect must be greatly reduced.
The choice of medicine in Qingyuan should be scientific and the spraying should be careful. There are no leaves on the fruit trees in spring, and some fruit farmers have very little water, and most of them pass by thickly. In fact, if you want to spray the medicine carefully through the rough skin, cracks, branches, etc., the water consumption per mu should not be less than 250-300 kg, otherwise, it will be difficult to remove the pests where they cannot be sprayed. In addition, some fruit farmers only pay attention to spraying on the trees, but do not pay attention to spraying on the ground.
