Second, what are the key points of pear fruit operation techniques?

1. Bagging method

First reach into the bag to expand the whole bag, hold the handle with one hand, hold the bottom of the bag with the other, put the young fruit in the middle of the mouth of the bag, and then squeeze the bag out of the mouth. On both sides of the middle handle, when all the bags are folded to the mouth of the fruit handle, on the left side of the bag mouth, tear off the length of the wire card at the mouth of the bag, and finally turn the wire flip card 90 to bend it tightly on the fruit handle, be careful not to tie it to the fruit rack and do not overstretch to prevent young fruit from growing from the stuck fruit handle. When the sleeves are finished, lift the middle of the bottom of the bag by hand to inflate the whole bag. The vents at the two bottom corners are opened and the young fruit is suspended in the bag and is not attached to the bag wall to prevent the sting of bees. Fruits and syrup, bacteria and exocrine pollutants rust and mildew for a long time.

2. Bagging time

20 days after flowering (about mid-May), when the young fruit reaches the size of the thumb, the bag is finished and the bag is complete. It will take about ten days to complete. It is too late to bag, the fruit has been stuffed, the effect is greatly reduced.

3. Preparation before bagging

Before bagging, the fruit should be carefully thinned according to the load requirements. The number of bags should be greater than the number of bags, so that there is room for choice when bagging.

Before bagging, insecticidal or bactericidal drugs must be sprayed 1-2 times, with emphasis on spraying the fruit surface and killing the fungi on the fruit surface. The drug is mainly targeted at pear black spot, fruit rot, yellow powdery mildew and cutting powder. Spray 70% methyl tarp 800x solution plus 10% cypermethrin 2500 times solution plus 50% monocrotophos 2000 times solution. Monocrotophos should not be added in pear orchards without Tenebrio Molitor and Kang's whitefly. Within ten days after spraying, the sealing gasket has not been completed and the rest should be refilled once.
