Detailed Explanation of Key Technical Points for Greenhouse Peach Cultivation and Management
I. Early training, early shaping, early fruiting. Because greenhouse peach trees are planted at high density, in order to obtain relatively high early income, shaping and flower bud development must be completed within one year: vigorously promote growth in the early stage for early shaping, then control growth in the later stage to produce more flowers. When shaping, whether using the slender spindle form or the "Y" form, yield must be given top priority. Not only should pinching be done multiple times under the premise of adequate fertilizer and water supply to promote more secondary and tertiary branches, but permanent fruiting must also be considered, that is, the branches being trained should not be tipped so they maintain a certain

Summary of Experimental Trials on Delayed Cultivation Techniques for Hongxue Peach in Plastic Greenhouses
Hongxue peach is an extremely late-maturing peach variety. When cultivated in the open field in our county, the fruit is difficult to ripen due to late-autumn rainfall and frost. Therefore, starting in 2001, we conducted delayed cultivation trials in plastic greenhouses using technical measures such as early promotion followed by later control, delayed flowering, bagging to protect against rain, and covering the greenhouse to regulate temperature, prevent frost, and protect leaves. The results showed that facility-grown Hongxue peach bore fruit in the second year after planting, entered full production in the third year, could delay fruit ripening by about 20 days, and markedly improved fruit maturity and the rate of high-quality fruit.

Detailed Introduction to the Greenhouse Peach Variety Snow Red
This variety was self-selected and self-bred, and named Snow Red. Under open-field cultivation, the ripening period is generally in early to mid-June (Gregorian calendar); under greenhouse cultivation, the ripening period is generally in mid-April. Greenhouse Snow Red has a round and regular fruit shape with a flat top, an average single fruit weight of 150 grams, and a maximum fruit weight of 350 grams. The color is bright red, delicate milky white, the flesh is white, the texture is firm and fine, it tolerates transport, has a strong aroma, is sweet and juicy, and its soluble solids content reaches 12-14%. Its marketability is extremely high, and it is known as Early White Pagoda. Its price is generally 3-5 times higher than that of nectarines on the market at the same time, and it can compare with imported high-end fruits. As of now, 95% of peach tree varieties cultivated under protected conditions in our country are nectarines. Greenhouse Snow Red peach is the first peach variety for protected cultivation in our country at present.

How to prevent fruit russeting in Huangjin pear? Causes and measures
Huangjin pear was introduced to our city in 2000. Through top-grafting and variety replacement, it has now expanded to 2567 hectares, and began bearing fruit in 2001. However, in production it was found that the fruit surface of Huangjin pear is prone to forming fruit russeting, with the rate of good fruit at 30%-50%, seriously affecting the economic benefits of fruit growers. For this reason, we conducted investigation and analysis, identified the causes and proposed corresponding countermeasures. 1. Causes Internal factors: The occurrence of Huangjin pear fruit russeting is closely related to its peel structure. The fruit of Huangjin pear

What to Do About Severe Fruit Russeting in 'Hwangkeum' Pears? Causes and Control Measures
1. Causes of severe russeting in bagged fruit 1.1 Improper pesticide use during the young fruit stage. 'Hwangkeum' pears are sensitive to pesticides during the young fruit stage, which is very different from the management of 'Yali' pears. If the pesticide application procedures for 'Yali' pears are followed, russeting is bound to occur. 1.2 Orchard crowding, excessive canopy branch density, and poor ventilation and light penetration lead to russeting. At present, most pear orchards in our area are high-density orchards developed in recent years, with spacing mostly 4 m x 4 m or 3 m x 4 m, and trees about 15 years old. In pursuit of early bearing and high yield, the high-yielding tree form used for 'Yali' pears has been adopted, resulting in a top-heavy tree with excessive retained branches, which makes the orchard air humidity, especially inside the canopy, too high and lasting too long. In this humid environment, physiological factors and the synergistic effect of pesticide residues on the fruit surface aggravate russeting in bagged 'Hwangkeum' pears.
