Rational application of scientific fertilization The roots of fruit trees are the organs for absorption and storage of nutrients, and timely fertilization is conducive to the continuous increase of production of fruit trees in the coming year. How to fertilize scientifically? Experts suggest that it is more appropriate to use circular or radial fertilization. The main approach is to dig a tree tray about 40 cm deep below the perimeter of the canopy projection. This is mainly farmyard manure, which can be appropriately mixed with phosphorus, potassium, and trace fertilizers. Kg is best. Pay attention to less rooting when fertilizing, and timely watering after fertilization. Foliar fertilizer can be used 5% urea or 0.3% ~ 0.5% potassium dihydrogen phosphate, spray once every 10 days, 2 or 3 times in a row.
Peach fruit harvested in the event of rain in more weather may not need to water, if the drought is too long, you can fill the water, as appropriate, while doing a good job of drainage flood control, cultivator weeding, to prevent soil compaction, in the soil freeze before pouring frozen Water once.
Pay attention to pruning to ensure that the flower buds form a good fruit After harvesting, special attention should be paid to fruit tree pruning, maintain a good tree shape, make the tree airy and transparent, and promote photosynthesis to ensure the formation of flower buds. First of all, we must eliminate the misshapen branches such as dense branches, diseased branches, overlapping branches, and thin and weak branches to ensure adequate lighting conditions. The upright backbone branches soften and open angles and ease the tree potential. The erect leggy branches on their backs have the softening or twisting of the growth space to control their growth. After the result, sagging and weak branches can be properly retracted to reduce nutrient consumption. Long fruiting branches can be appropriately shortened and cultivated into compact fruiting groups.
In addition, cultivating tillage after removing the fruit should remove the orchard weeds. The depth of the cultivator is usually between 5 cm and 10 cm. After the leaves fall, the orchard is fully cleaned once and the deciduous weeds are buried under the trees.
To prevent pests from infesting and harvesting fruits, special attention should be paid to the prevention and treatment of diseases and insect pests such as peach tree leeches, leaf miners, and spider mites. For fluidic diseases, try to avoid mechanical damage to the branches, and remove the glue immediately after the glue flows. Use quicklime, lime sulfur, salt, vegetable oil, and a suitable amount of water to form a protective agent. Apply to the affected area or cut the mouth. . For pests, choose 50% carbendazim 800 ~ 1000 times, or 50% mancozeb 800 times, plus 25% of the pyrethroids and other pyrethroids for control, spraying 2 times .
