Production of raw canned snow pear
Canned raw snow pear is a canned variety with white color, sweet and sour taste, crisp tissue and rich flavor. Compared with the traditional cooked process, the raw assembly process can reduce steam consumption by 30%, pear consumption by 10%, ton cost by 5%, and pulp brittleness by 80%.
(1) technological process
Raw material acceptance → cleaning → folding, peeling → slicing, seed nest → trimming → sorting → canning → juice injection → exhaust, sealed → sterilization, cooling → into storage
(2) production method
1. Hebei Zhaozhou Xuehua pear is selected for raw material acceptance, the raw material should be fresh and full, free from diseases and insect pests, no mildew and rot, and the transverse diameter of the fruit is not less than 5.5 cm.
2. Clean water is used to remove sediment and impurities attached to the surface.
3. The core temperature of folding and peeling feeding is not less than 10 ℃. Fold the handle and peel it mechanically.
4. Cut and cut the seed nest in two halves, and dig out the seed nest and pedicle tendons.
5. Trim and remove mechanical injuries, insect pest spots, residual pericarp, calyx, etc., and soak in 1%-2% salt water to protect color.
6. Sorting is separated according to the size, color and maturity of the fruit. Remove unqualified fruit pieces such as soft rot, discoloration, diseases and insect pests, scars, etc.
7. 500ml victory glass cans are used, each of which is filled with 290 grams of snow pear. Pay attention to the neat arrangement of pear slices when canning.
8. Juice is injected into sugar juice, and the concentration of sugar juice varies according to the ratio of sugar to acid in pulp. When opening the can, the concentration of the sugar solution is 14%-18% determined by the refractometer, and a certain amount of citric acid is required to be added to the sugar solution.
9. Exhaust and seal the canned snow pear with sugar juice is sent to the exhaust box for exhaust, and the can can be sealed when the central temperature of the tank is above 85 ℃.
10. The cans after sterilization, cooling and sealing should be sterilized as soon as possible, kept in the sterilizer at 90 ℃ ~ 95 ℃ for a period of time, and then sterilized at 100 ℃.
11. Dry the cooled canned snow pear and apply antirust oil into the warehouse.

The greenhouse time of apricot cultivation in protected field
General apricot varieties must undergo a low temperature period of 700 to 1000 hours below 7.2 ℃ in order to break dormancy. Therefore, protected cultivation must be heated up after meeting the low temperature demand of apricot in order to be successful. Early heating apricot trees can not sprout and blossom normally, when serious, it will cause a large number of buds to fall off, irregular florescence, serious flower and fruit drop. The heating time should also be carefully determined according to the low temperature demand of the variety and the weather conditions. 1. The holding time of plastic greenhouse the thermal insulation performance of plastic greenhouse is poor, apricot trees must be under natural conditions.

Prevention and control of fruit shrinkage disease of jujube
The occurrence of jujube fruit shrinkage disease is positively correlated with the density of piercing sucking insects, and the disease is often prevalent due to high atmospheric humidity, especially in intermittent rainfall or continuous overcast days. Control methods: if the susceptibility index of ① is relatively high last year, we should first clean up the fallen leaves and fruits in the jujube orchard and concentrate on treatment so as to cut off the source of transmission. ② strengthens the fertilizer and water management of jujube orchard and improves the resistance of trees. For older trees, scrape and burn the old bark before sprouting, and spray stone-sulfur mixture on the whole tree. Chemical control of ③: using fungus No. 1
