Processing Methods and Technical Key Points for Canned Pears in Syrup
(1) Process flow: Raw material selection → raw material preparation → precooking → filling into cans → exhausting → sealing → sterilization → cooling. (2) Process key points. 1. Raw material selection: Choose varieties that are at 80% maturity, with thick flesh, small core, tender and fine texture, few stone cells, uniform fruit shape, smooth fruit surface, strong aroma, and good flavor. Such as Changba pear, white pear, Ya pear, Laiyang pear, Xuehua pear, etc. 2. Raw material preparation: Grade by fruit transverse diameter. Remove diseased, insect-damaged, moldy, and externally damaged fruit. Wash clean with water, soak in 0.1

How to keep pears fresh for storage? Master these methods to store them longer
(1) Raised-bed pit storage method. This is a main storage method used in the Huangxian Changba pear producing area. Before harvesting the pears, choose between-row spaces in the orchard with good ventilation, cool and dry conditions, and a low water table. Build raised beds running north-south, with a bed width of 1.5 m to 2 m; the bed length depends on the storage quantity. The bed surface should be about 10 cm above the ground, slightly higher in the center and slightly lower on both sides, with ridges about 15 cm high built up around the perimeter. Spread a layer of fine sand 5 cm to 10 cm thick on the bed surface. At the four corners of the bed ridges and along the two long sides, drive a wooden post every 750 mm, with a post height of 750

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.

Scraping pear tree bark in winter is the key to growing good pears
The farming proverb says: "If you want to eat good pears, scrape the bark in winter." In the cold winter season, scraping off the old bark of pear trees that have already borne fruit can effectively eliminate fungal spores such as pear scab, ring rot, anthracnose, and pear rust that remain inside and outside the old cracked bark of pear trees, as well as the eggs of various pear tree pests such as the pear psyllid, aphids, fruit borers, and scale insects, ensuring robust production of pear trees with high quality, high yield, and high returns. Scraping must be thorough When scraping pear tree bark, you must remove the old cracked bark, rot disease, pear scab, ring rot, anthracnose, scale insects, pear psyllids, aphids,

Winter control of psyllids in pear orchards leads to good pears in autumn
The pear psyllid is the most important pest on pear trees. It can damage pear leaves, causing blighted spots, weakening tree vigor, and reducing fruit quality and yield. It produces 4-5 generations per year. Adults are divided into winter and summer forms. Winter-form adults overwinter in the cracks of pear tree branches and trunks, with a few in weeds, fallen leaves, and soil. Integrated control should target their overwintering sites. 1. Orchard sanitation. Clear away fallen branches, fallen leaves, and weeds in and around the orchard, bury them deeply or burn them, to reduce the overwintering pear psyllid population. 2. Bark scraping. Spread plastic film on the tree tray

Dangshan crisp pears enjoy a bumper harvest, and fruit farmers are busy picking
Dangshan crisp pears are famous at home and abroad, with large fruit and a small core, bright yellow and beautiful appearance, thin skin and abundant juice, crisp and sweet, and they also have the functions of quenching thirst and promoting salivation, relieving heat and cooling, resolving phlegm and moistening the lungs, stopping cough and calming asthma, and promoting bowel movements and urination. Dangshan is a comprehensive fruit-growing region led by crisp pear production with many kinds of fruits coexisting. The county horticultural farm's "Dangyuan" brand crisp pears, which won the "International Longma Gold Award", the orchard farm's "Feicui" brand crisp pears, the county fruit science institute's pollution-free bagged crisp pears, the Kouzi tribute pears of Xinanzhen Town, the "Huangkao pears" of Liangli Town, and the high-yield, high-quality premium variety crisp pears of Tangzhai and Lizhuang Towns, among several

Fengxiang Pear Variety Introduction: An Excellent Variety Known as the King of Pears
Fengxiang pear was bred by the Zhejiang Academy of Agricultural Sciences from a cross of New Century x Sanhua. It was introduced to our farm's base in 1999, and in 2000, 85% of the trees bore fruit, with an average yield of 2.2 kg per tree. By 2002, the yield reached 38.5 kg per tree, with an average of 29 kg per tree and a per-mu yield of 1523 kg, ranking first among the 36 pear varieties at the base. This variety has thick, sturdy branches and vigorous growth. One-year-old branches are yellow, and in the 2nd and 3rd years the branches turn brown, with no rust spots and a glossy sheen. It is resistant to high temperatures, tolerant of poor soil, highly adaptable, early-bearing, produces abundant pollen, has a high fruit-setting rate, and yields abundantly and consistently.

Detailed Explanation of Key Techniques for Ventilated Storage of Pears
Ventilated storage of pears is a simple method that uses the natural low temperatures of winter, employing a ventilated storehouse with large day-night temperature differences and heat-insulating and warmth-retaining properties, so that the pears are kept under relatively stable, lower temperature conditions, delaying decay and allowing good storage. The main techniques are: after the pear fruit is harvested, it undergoes pre-storage and injury sorting, is packed into baskets and put into the storehouse, and stacked with ventilation. According to the temperature difference inside and outside the storehouse, windows should be opened or closed promptly and flexibly to regulate the temperature and humidity inside the storehouse, keeping the temperature as close as possible to -3 to 1°C and the relative humidity between 85% and 93%. In severe cold seasons, attention must be paid to preventing freezing, especially for

Detailed Guide to the Cultivation Key Points of Japanese and Korean Pears
Select suitable rootstocks and cultivate virus-free vigorous seedlings: The suitable rootstock varieties are sand pear, Yunnan pear and Chuan pear; in the southwest region, Chuan pear and Yunnan pear are preferable. When establishing an orchard, plant virus-free seedlings as much as possible and configure suitable pollinizer trees. Rational close planting to increase per-unit yield: The trees of Japanese and Korean pears are relatively smaller than Chinese pears, with shorter internodes and more compact canopies, so the planting density should be appropriately increased, using more plants per unit area to raise the yield per unit area. The spacing between plants and rows depends on the training system used, the terrain of the orchard and the fertility of the soil. That is, small-crown sparse

Analysis of the Introduction Performance and Development Strategies of Southern Pears in Hezhou
According to the deciduous fruit development concept of "southern pears and northern peaches" proposed by the Ministry of Agriculture in 1996, Hezhou City, Guangxi, began introducing southern pears from Zhejiang University, Guilin, Guangxi, and other places in 2000. A total of 11 southern pear varieties were introduced, and the current cultivation area is 1066.67 hm2. It is expected that the pear output in 2006 will reach 25,000 t. Based on current introduction observations, the soil, climate, and other natural conditions in Hezhou City are very suitable for the growth of southern pears. Many varieties show advantages such as high and stable yield, good taste, rich flavor, and strong resistance. The products are widely welcomed by consumers in the market.
