Harvesting technology of pear fruit

1. Note that toxic pesticides are prohibited in the near-mature stage, 20 days before harvest in bagging orchards and 30 days before harvest in bagging orchards. 10 days before harvest, the pear orchards with ring disease can be controlled with chlorothalonil 500 times plus green Fenwei 3 1000 times. Pear orchards damaged by pear planthoppers can be controlled with 2% global eagle 5000 times or 1.8% insecticidal mites 4000 times plus 5% acetamiprid 4000 times plus Gaojin Zengling (each branch with water 30kg) 20 days before harvest.

2. Harvesting personnel should cut off their nails or wear clean and soft gloves and choose fruit containers with smooth or soft inner walls. When picking the fruit, hold the fruit in the palm and lift it up to the place where it is born, so that the fruit falls off and is placed lightly in the fruit-picking container. When picking the fruit, do not pull it hard. Put it in a cool and ventilated place after harvest, and it is forbidden to be exposed to sunlight or rain. Fruit picking should avoid rainy days, wet dew or high temperatures at noon. It is strictly forbidden to mix the fallen fruit on the ground and the fresh fruit picked.

3. The harvest time determined for storage and long-distance marketing can be picked early; the wine used for local fresh sale and processing of fruit juice should be harvested after ripening, but must be harvested before the pulp softens. Early-maturing pears such as Cuiguan can be picked early, mid-and late-maturing varieties such as Huanghua pear can be picked late, and bagged fruits can be picked later. Refrigerated products should be collected every 1 or 2 sunny days in case of continuous overcast or heavy rain.

4. Fruit commercialization treatment mainly includes fruit selection, → grading, → single fruit packaging, → packing and so on.

When selecting fruit in ①, the disease and insect fruit, deformed fruit, mechanically damaged fruit, small fruit and fruit that do not meet the hygienic index were first removed.

② was graded according to the size and shape of the fruit.

③ single fruit packaging for distant sales, cold storage should be single fruit packaging, packaging materials, such as net cover, packaging paper, bagged pear fruit can not be bagged as a single fruit packaging.

④ is packed in the same box with the same batch of fruits of the same grade, and the fruit size is required to be basically the same in the same box. When placing the fruit, the fruit should be arranged neatly, the fruit stalk should be sideways facing, and the layers should be separated by cardboard.

5. Refrigerated fruits are first packed in plastic bags, and then packed in plastic boxes. They are stored in a freezer with a refrigerated temperature of about 5 ℃, which can be refrigerated for a long time.
