Correct choice of site and variety
It is not advisable to choose a viscous land for the establishment of a garden. It is easy to choose sandy soils and loam soils with good drainage, deep soil texture with good water conservancy conditions, and cherry plants with strong resistance to pests and diseases.
Strengthen Orchard Soil Water Management
Increase the application amount of organic fertilizer, balance fertilization, pay attention to the application of trace element fertilizer, biological bacterial fertilizer, fruit tree compound fertilizer, improve the rhizosphere environment of the tree, increase soil permeability, increase the nutrient level of the tree, and increase the tree vigor. Reducing the main measures for the occurrence of fluid injection.
Cherry trees are fruit trees that require more water but are not tolerant to waterlogging. They need to be watered a small number of times to meet the water demand for tree growth and development, and to avoid water accumulation in the rhizosphere of trees. The rhizosphere has poor permeability due to spasm, resulting in poor drainage and aggravating the occurrence of physiological fluid injection. In the late growth period of cherry, attention should be paid to controlling irrigation, controlling the growth of shoots on the cultivation, strengthening the nutrient accumulation level of the tree, and enhancing the resistance of the tree body.
Reasonable pruning
Cherry winter pruning can easily lead to gummy disease. Pruning should be done before sprouting in early spring to avoid excessive or sparse removal of large branches, avoiding large swarf cuts, so as not to invade bacteria, and to cut the kerf to heal. Agent to promote early wound healing. In the event of a tree disorder, it is necessary to eliminate large branches each year to reduce the adverse effects on tree vigor. The branching time should be appropriate. It is better to pull the branches from April to August, and often move the position of the rope to avoid the breeding and invasion of germs.
Scratch treatment spot
The lesions are limited to the surface layer. After winter or spring rains and snow, the fluid is softer and can be scraped off with a guillotine. At the same time, 80% ethylicin EC 50 times or 50% thiram can be applied to the wound. 50 times liquid, then coated with Bordeaux fluid protection; or directly coated with 5 Baume degree lime sulfur agent for prevention and treatment.
Integrated control of pests and diseases
In winter and spring, the trunks and branches are coated with white, which can prevent and treat many diseases and insect pests. At the same time, it can prevent freezing injury and sunburn. The white-painted parts are mainly trunk positions, and the main branch bifurcation and main stem near-ground parts should be painted more. Cleared the garden from December to January, scraped the hard plastic lump and the necrotic tissue underneath, cut off the dead branches, cleared the fallen leaves, concentrated burning, and reduced pathogenic bacteria. Spray copper preparations and agricultural streptomycin 3 to 4 times during fall leaf and dormancy in early spring to reduce and avoid initial infestation. In addition, the lime sulfur mixture is effective for both fungi and bacteria. It covers the ground and trees in a dormant period. It not only kills all kinds of germs but also kills pests. The effect is ideal.
