Proper autumn management of peach trees can increase peach orchard yields next year
The period from after peach harvest to before leaf fall is a critical time for nutrient accumulation and flower bud differentiation in peach trees. The quality of management directly affects the peach trees' ability to overwinter and resist cold and their growth and fruiting the following year. Therefore, fruit growers should pay attention to management work after peach harvest. Fertilization

Comprehensive Control Methods for the Peach Borer Moth in Peach Cultivation
The peach borer moth larvae bore into and feed on peach fruit, causing gumming; the fruit discolors and drops, or the interior becomes filled with insect frass, making it unfit to eat, and this has a great impact on both yield and quality. I. Occurrence pattern. In Shandong, this pest occurs in 2-3 generations per year, mainly overwintering as mature larvae in cocoons inside damaged mummified peaches, bark crevices, gaps among loose stones in embankments, chestnut burs, sunflower heads, castor seeds, and corn and sorghum stalks, with a small portion overwintering as pupae. In Shandong, the first moth emergence of the overwintering generation occurs in mid-May, with the peak in early to mid-June; most eggs of the 1st generation are laid on early-maturing peach varieties, with the most eggs laid on the ventral (belly) side; the newly hatched larvae appear in mid-to-late June and mainly damage early-maturing peach fruit, boring into the fruit to feed; mature larvae spin cocoons and pupate at the stem cavity of damaged fruit and in bark crevices. The 1st-generation adults begin emerging in early July, with the peak from late July to early August; adults are highly selective in egg-laying, basically laying eggs on late-maturing peach varieties and pomegranates; newly hatched 2nd-generation larvae are found in mid-to-late July, with the peak in early to mid-August; by late July, larvae are already found maturing and pupating. The pupation peak is in mid-to-late August. As late-maturing peaches begin to be harvested, adults then move to other crops to lay eggs and continue causing damage.

What should be noted when pruning peach trees after harvest?
Peach trees themselves have the characteristics of vigorous growth, strong branching capacity, excessive shoot growth and many branches. Most fruit growers, after harvesting peaches (especially early and mid-season varieties), do not pay attention to post-harvest pruning, which leads to an increase in water sprouts, a closed canopy, poor ventilation and light penetration, affecting flower

How should peach trees be cultivated in protected facilities?
1. Variety selection Nectarine and peach varieties suitable for protected cultivation mainly include Shuguang (Huaguang, Yanguang), Zaohong No. 2, Weifang sweet nectarine, Annong Shuimi, Chunyan, Qingyan No. 1, Zaolu flat peach, Yuhualu, Shazi Zaosheng, etc. The rootstock is wild peach rootstock or Dongxue honey peach.

How to prevent and treat peach tree chlorosis? A full breakdown of practical methods
1. Causes 1. Iron deficiency The main causes of iron deficiency in protected-cultivation peach trees: ① Planting density is high, some even reaching 1 m by 0.8 m, the land nutrient area occupied by each tree is small, roots cross each other, and the iron ions released in the soil cannot meet the absorption needs of the root system.

How to prevent and control anthracnose in peach trees? These methods are very practical
Along with the adjustment of the agricultural industrial structure, the planting area of peach trees in our county has continued to expand. Due to the influence of various factors such as climatic conditions, varieties, and management, peach anthracnose occurs rather severely and has a relatively large impact on peach yield and quality. Effective prevention and control of anthracnose is very important for increasing yield

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

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

Pollination, Fruit Thinning and Harvesting Techniques for Peach Tree Cultivation
Practice has shown that to achieve high yields in peaches, pollination, fruit thinning and harvesting must be carried out at the right time. Pollination: During the flowering period of peaches, rainy and low-temperature weather often occurs, creating obstacles to normal pollination. This contradiction is even more pronounced for pollenless varieties. To achieve high and stable yields in peaches,

For high quality and high yield, peach trees must not be given one-sided nitrogen fertilizer
Case study: Nowadays consumers have higher requirements for the quality of peaches. Some peaches are small and unpopular, and some peaches do not store well and rot after a few days. In order to meet market needs and improve the quality of fresh peaches, fruit growers try every means to increase fertilization and irrigation of peach trees
