Precautions for spraying fruit tree gardening

1. Spraying needs to be meticulous. When the fruit trees are cleared, generally in the spring, the fruit trees have not yet grown leaves, and the rough bark, cracks and branches should be sprayed evenly when spraying. The water consumption per mu is about 250-300 kilograms, in order to ensure that every place can be evenly sprayed, in order to effectively remove pests.

2. Spraying is needed under the trees on the ground. The topsoil is a wintering ground for pests and diseases, and when the temperature rises, they sting trees. When spraying, the ground is the focus of the garden, if it is not sprayed, it will continue to spread a lot of pests and diseases.

Fruit tree winter gardening, is to clean up the diseased branches and leaves under the tree after the fruit tree enters hibernation, scrape off the old bark, spray fungicides and insecticides with strong permeability and long effective period, and eliminate the pests and pathogenic bacteria that are ready to overwinter or just break the dormancy preparation activities.

According to the time of the garden, it is divided into late autumn and early winter, and spring. Some places attach importance to the former, some places only carry out spring garden cleaning, and if possible, try to carry out both garden cleaning. Fruit tree clearing integrates sterilization, insecticide, tree raising, and protection and wintering, which plays an important role in improving orchard management, disease prevention and treatment.

Generally, the garden is cleared after fruit picking, natural physiological leaf fall2 3 and before budding in spring. The ideal time to clear the garden is in autumn. Next, I will introduce you to a few details of the fruit tree garden.

1. The ideal time to spray.

The purpose of clearing fruit trees is to eradicate overwintering bacteria and pests, and the more important means is spraying. However, the breeding of bacteria in spring, the sting of pests is directly affected by the temperature, and after the sting, when the temperature stabilizes above 18, it is the ideal time to use medicine. The temperature is low, there is no activity of pests and diseases, it is difficult for the medicinal properties to play a role, and the control effect is also greatly discounted.

2. Orchard cleaning should be serious.

Most of the germs and eggs overwinter in the dead branches and leaves, diseased fruits, and dead fruits, and it is important to clear these things out of the orchard. However, most growers do not pay enough attention to this, and very few can seriously clean the orchard floor.

3. The choice of pharmacy should be scientific.

Fruit trees need to clear the garden in autumn to have a long effective period, if the agent can quickly pass through the protective layer to the pests or pathogenic bacteria lurking in the bark, diseased branches, and diseased buds, the effect will be better.

When choosing a drug, it is necessary to look not only at the active ingredients of the drug, but also at whether the dosage form of the drug has these two points.

4. Spraying should be meticulous.

Deciduous fruit trees have no leaves, and most fruit growers use very little water, and most of them are coarsely sprayed. In fact, if you want to spray the medicine carefully all over the coarse bark, cracks, branches, etc., the water consumption per mu should not be less than 250 300 kg. Otherwise, where you can't spray, it will be difficult for pests.

5. Spray under the trees on the ground.

Most growers only pay attention to spraying on the trees, and few pay attention to spraying the ground. It is important to know that the topsoil is the overwintering site for many pests and diseases, and when the temperature rises, they will emerge and sting on the trees. Therefore, the ground is also the focus of the garden.

In the process of fruit tree planting, the nutrients can be supplemented by appropriate water-soluble fertilizer of fertile leaves.

The best medicine of Qingyuan is stone sulfur mixture (concentration of Baumé 5 degrees), followed by fungicide. Such as carbendazim, tobuzin can be. The best is the stone sulfur mixture! (Sterilization and insecticidal eggs)!

The garden cleaning agent is a mixture of engine oil and stone sulfur mixture microemulsion, which is diluted 1000 times after grape leaves fall and before flower bud germination and sprayed twice, which has a good effect of disease prevention and insect control.
