Five measures for fruit setting of newly planted peach trees in the same year

1. Reasonable close planting. The planting density of 1m × 1m, 1m × 1.25m or 0.8m × 1m can obtain enough branches and flowers in the current year and higher yield in the next year. After canopy closure, reasonable thinning can be carried out.

2. Fertile soil management. Before planting, dig a planting ditch 70-80 cm deep. When digging the ditch, separate the raw soil from the mature soil. First fill 10-15 cm of straw chaff at the bottom of the ditch, then fill 10 cm of mature soil, and then apply 50 kg of organic fertilizer and 5 kg of diammonium phosphate to the soil per mu, fill it and water it to ensure sufficient nutrition. After planting in the middle and late March, plastic film will be covered to keep warm and promote growth.

Third, many times to pick the heart. The excessive branches appearing in the growth of peach trees should be wiped bud and removed in time to promote secondary branches, cultivate the trees into trunk trees with central leading trunk, and remove the core when the secondary branches grow to 20 cm to promote tertiary branches.

4) Control growth. Generally, phosphorus and nitrogen can be applied from the end of June to the beginning of July to promote flower bud differentiation. However, when the secondary branches grow to 0.25-0.3 meters, 15% paclobutrazol 300 times wettable powder should be sprayed on the leaves, so as to achieve quantitative and uniform spraying, especially on the top growth point of the new shoots. Spray enough to properly control growth.

5. Prevention and elimination of diseases. On the basis of reasonable shaping and pruning and ensuring ventilation and light transmission of trees, cut off diseased fruits, diseased leaves and diseased branches, spray 4-5 degree stone sulfur mixture once before germination, and spray 2500 times or 3000 times of Mieshanling to control leaf rollers, red spiders and bugs when pests occur.
