The New Peach Tree Fruits Five Measures
First, rational dense planting. With a planting density of 1m 1m, 1m 1.25m or 0.8m 1m, sufficient branches and flowers can be obtained in the year and higher yields will be obtained the following year, and reasonable re-harvesting will be carried out after the closure of vegetation. Second, fertilizer and soil management. Before planting, dig 70-80 cm deep planting trenches. When digging trenches, separate the raw soil from the mature soil. First, fill the grasshopper 10-15 cm at the bottom of the trench, then fill in the mature soil 10 cm, and then apply the organic acid per acre. Fertilizer 50 kg, diammonium phosphate 5 kg mixed with soil and watered to ensure adequate nutrition. In the middle and late March, after the planting, it is covered with plastic film to promote heat preservation. Third, many topping. Excessive shoots appearing in the growth of peach trees shall be promptly brushed and picked up to promote secondary branches. The tree shall be cultivated into a trunk tree with a central leading position. When the second branch grows to 20 centimeters, it will be picked again and promoted. Three branches. Fourth, control growth. Phosphorus and nitrogen fertilizers are generally applied at the end of June to early July to promote flower bud differentiation. However, when the secondary branch grows to 0.25-0.3 meters, it should be sprayed with 15% paclobutrazol 300 times wettable powder to achieve quantitative and uniform spraying, especially to the top of the new shoot must be sprayed to spray full, With proper control of growth. Fifth, disease prevention and harm. To cut and remove diseased fruits, diseased leaves and diseased branches on the basis of reasonable pruning and ensuring the ventilation and light transmission of the trees, spray 4-5 degrees lime sulfur before germination, and when the insects occur, they can be sprayed in a targeted manner. Lee 2500 times or 3,000 times the moth alfalfa control leaf roller moth, red spider, stink bug and so on.
