The best time for clearing the park in spring
In recent years, the risk of pests such as defoliation, rot, red spot disease, black spot disease, whitefly, aphids and leaf miners has increased. There are many reasons for this. One of the important reasons is that the spring is not scientific. The spring garden can effectively prevent and kill overwintering pests and diseases, reduce the base number of pests and diseases, supplement tree nutrients, promote budding, flowering and fruiting, and also prevent the occurrence of late spring. This general grower is clear. However, when the spring is the best when it is sprayed, there are very few farmers who can say it. The best time for spraying the spring garden is to eradicate the wintering germs and pests. The most important measure is spraying. However, the breeding of spring bacteria, pests directly affected by temperature, after convulsions, the temperature stabilized at 18 °C above, is the best time to use drugs. The temperature is low, the pests and diseases have no activity, and the medicinal properties are difficult to exert. The control effect is also greatly discounted. Clear Garden in spring must pay attention to the best time for spraying. Orchard cleaning should be serious. Most of the germs and eggs are overwintering in fallen leaves and fruit and stale fruits. It is very important to clear these things out of the orchard. However, most fruit growers do not pay enough attention to this, and it is negligible to seriously clean up the orchard grounds. Pharmacy selection should be scientific and some fruit growers like to use lime sulfur in Qingyuan, but they are reluctant to buy quality products. The quality of their own cooking systems is often very poor, and some like to use Fumei, resulting in a large amount of pesticide residues, affecting fruit Sales. Insecticide and sterilization products should be selected pollution-free green products or biological agents, not only to ensure high efficiency, but also pay attention to safety. Spraying should be careful to clear the park without leaves, most farmers use very little water, most of them are sprayed. In fact, in order to spray the medicine carefully throughout the rough skin, cracks, branches, etc., the amount of mu should not be less than 250-300 kg of water. Otherwise, pests cannot be removed where they cannot be sprayed. Most of the fruit trees on the underground trees are sprayed with pesticides, and few people pay attention to spray the ground. It is important to know that the topsoil is a wintering place for many pests and diseases, and they will emerge from the trees when the cold temperature rises. Therefore, the ground is also the focus of Qingyuan. Direct spraying on the trees does not spray the ground, making more pests and diseases become "net of fish."
