Key Technical Points of Tree Body Management in Peach Cultivation
Strengthen tree nutrition. Branch growth and leaf area expansion provide the basis for producing nutrients for flower bud differentiation, which is beneficial to flower bud differentiation. Excessive fruiting in the current year will weaken tree vigor, leading to reduced shoot growth in that year. Conversely, if the plant grows too vigorously, it consumes

Key Technical Points and Application Methods of Long-Shoot Pruning in Peach Trees
Long-shoot pruning is a pruning technique that basically does not use heading cuts, and only employs thinning, renewal cuts and long-shoot training. Because heading cuts are basically not used, the current-year shoots after pruning are relatively long, with fruiting branches averaging generally 50-60 cm in length. Long-shoot pruning has the advantages of being simple to

Five Key Technical Measures for Newly Planted Peach Trees to Set Fruit in the Same Year
1. Reasonable close planting. Using a planting density of 1 m × 1 m, 1 m × 1.25 m or 0.8 m × 1 m can produce sufficient branch volume and flower quantity in the same year, and a relatively high yield the following year; after the canopy closes, carry out reasonable thinning. 2. Fertilizer and soil management. Before planting, dig

Management Measures and Technical Points for Peach Trees After Fruit Harvest
Most peach tree varieties mature early, and there is a long growth period from fruit harvest to leaf fall. This is precisely the critical period for nutrient accumulation and flower bud differentiation in peach trees, and the quality of management will directly affect the peach trees' overwintering and the growth and fruiting of the following year. Therefore, after fruit harvest, peach trees should adopt
