How Is a Pear Processed? An Introduction to the Production Methods of Several Common Pear Products
Pears have a long history of cultivation in China. At present, the total pear output accounts for about 20% of the country's total fruit output, making pears the fruit with the highest output in China. Pears come onto the market in a relatively concentrated period, and most pears do not store well, so they flood the market quickly and prices are relatively low. If they are properly processed, they can be supplied to the market year-round. The following introduces several processing methods for pear products. I. Pears in Syrup 1. Process flow: Raw material selection -> washing -> removal of fruit stalk and peeling -> cutting and removal of core -> trimming -> color protection -> pre-cooking -> sorting -> filling into cans -> heating and exhausting -> sealing -> sterilization

What are the control methods for the jujube tree tortoise wax scale?
(1) Manual removal of the pest source: during winter and in early spring in March of the following year, use a stiff-bristled brush to scrape the insects off the branches and collect and kill them. If snow or fog freezes on the branches with a thick layer of ice, you can directly strike the branches to shake off the ice, and the insects will fall with it. (2) Protect and utilize natural enemy resources: this pest has many natural enemies; a single predatory Chilocorus kuwanae can prey on thousands of these insects in its lifetime; the larvae of the long-shield golden small wasp can parasitize under the pest's abdomen and feed on the scale eggs. The larvae of the long-shield golden small wasp can parasitize under the pest's abdomen and feed on the scale eggs. (3) Chemical control:

When to plant Taiwan Indian jujube? A detailed guide to cultivation methods
1 Timing It is usually planted from February to March (in frost-free areas of the south, planting can be advanced to December to February), with a high survival rate and good growth, and it can flower and bear fruit in the same year. After the fruit is harvested the following year, superior varieties are grafted again between February and March. 2 Density Moderate close planting can follow (1) 3m x 4m, 55 plants per 666.7 sq m; (2) 3m x 5m, 44 plants per 666.7 sq m; after 3 years it can be changed to the two methods of 6m x 4m and 6m x 5m. 3 Carry out mixed planting or interplanting Because

How to prevent and treat gummosis in peach trees? A detailed guide to practical methods
1. Distribution: Peach gummosis, also known as resin disease, occurs commonly in all peach-growing regions of our country, and is especially severe in the south. The causes are complex, and it is not easy to completely control. Gumming weakens tree vigor, affects fruit quality, and can even kill branches and trees. 2. Symptoms: This disease mostly occurs on the branches and trunk of peach trees, and is most likely to occur at the main trunk and the forks of main branches. In the early stage, the diseased part swells slightly and gradually exudes a translucent gum, which worsens after rain. Afterwards the gum gradually becomes jelly-like, turns yellowish-brown after losing water, and becomes dark brown when dry. In severe cases, the bark cracks

How to prevent almond winter dieback? A detailed guide to practical methods
In northern regions, especially in areas with strong spring winds, winter dieback is prone to occur. The root system of almonds has no natural dormancy; although some cultivars can tolerate low temperatures of -18°C, winter dieback can also occur in windy, dry weather below -10°C. When transpiration water loss from branches reduces their water content to 35%, winter dieback occurs. Sometimes it also occurs on 2- to 3-year-old branches, causing serious effects on tree growth and fruiting. The main technical measures to prevent winter dieback are as follows: 1. Establish shelterbelts to create a good growing environment. Establishing shelterbelts,

What are the pest control methods for the pear lace bug?
This insect, also known as the army-matching bug, gathers as adults and nymphs on the undersides of leaves to pierce and suck sap, causing the damaged leaves to be densely covered with small white spots, or even to turn entirely pale, leading to early defoliation, affecting tree development and flower bud formation, and in severe cases causing the tree to bloom twice in the same autumn, damaging the following year's yield. This insect has a relatively mixed diet and can harm many fruit trees such as pear, apple, Chinese pearleaf crabapple, crabapple, peach, cherry, hawthorn, and jujube. [Occurrence pattern] It has 4-5 generations per year. Overwintering adults begin activity and lay eggs in mid-April, with an egg period of 10-15 days. The

Detailed Explanation of the Production Techniques and Methods for Seedless Candied Jujubes
1. Ingredients: 50 kg dried red jujubes, 30 kg soft white sugar, 100 g citric acid. 2. Key operating points: (1). Select milky-white stage jujubes that are large, have small pits, thick flesh and thin skin, and sort them into 3 grades - large, medium and small - for processing separately. (2). Sharpen one end of an iron tube 6-8 mm in diameter, pierce it in from one end of the jujube, and when pulling it out, bring the jujube pit out with it. With continuous operation, the pits are constantly pushed out from the other end of the iron tube. (3). Soak the pitted jujubes in clean water for 12 hours,
