Why do kiwi bags?

First, prepare before kiwi bagging

The young trees can be based on the strength of the fruiting mother branches. Each fruiting mother branch leaves 2 to 3 fruiting branches, each fruiting. Two to three fruits are left on the branches. As a result of weak and injured trees, the female branches should retain less or no fruits.

Second, the choice of kiwi bagging

The paper bag is preferably a single layer of beige thin waxy wood pulp paper bag, 15 to 18 cm long and 11 to 13 cm wide, with a slit in the middle of the upper mouth, iron wire on one side, and an opening of 2 to 4 cm on the lower corner.

If bagging is too early, it will easily damage the skin of the fruit stalk, which is not conducive to the development of young fruit. If the bagging is too late, the fruit surface will be rough, which will affect the bagging effect.

4. Spray medicine before kiwi bagging

The kiwi is sprayed with insecticide and fungicide in the whole garden before bagging. It can be sprayed with 2500 times solution of 20% anti-sweep, 2,000 times of 18%, or 2000 times of green kung fu, methyl tolbutin or carbendazim.

When bagging, use one hand to open the mouth of the bag, and put the good young fruit into the bag from bottom to top. The other hand will fold the bag from the slit to a uniform fold, and use the wire on the side of the bag to fold the folds. Tight, the solitary fruit on the fruit branch can be directly tied to the fruit bearing fruiting branch, the clustered fruit is tied directly to the fruit stalk, and the folded fruit bag is lined on the fruit stalk. Fruit stalk. Check whether the bottom of the fruit bag is open. If the bottom of the bag is completely closed, use scissors to cut the opening of 2 to 4 cm. The mouth is tightly sealed. When bagging, the inside and the outside should be gentle, and the sagging or upright branches should be fixed in time to prevent the wind from blowing.
