Can peaches be covered in a plastic bag on a tree?

OK. 1.The peach tree is a small deciduous tree whose fruit is used as a fruit, the flowers can be ornamental, the fruit is juicy, it can be eaten raw or made into preserved peaches, canned food, etc., and the kernel can also be eaten.

2.Generally, the bagging is started 30 days after flowering, and the bagging is carried out after the second physiological fruit drop and the hard core stage, and the bagging period is different for different varieties. 2 3 days before bagging the whole garden to spray 1 insecticide fungicide, the liquid medicine dry immediately after the bagging, bagging should be selected sunny, foggy days, not to be able to be bagged when there is dew on the surface of the young fruit, the appropriate time is 9 11 o'clock and 15 18 o'clock on sunny days.

3.Advocate the use of paper bags, paper bags have single and double layers, the color is white, yellow and orange 3 colors, requiring the bag to have good air permeability, small water absorption, strong paper strength, good light shading, soft paper, uniform coating of the inner bag, non-toxic thin wax layer and low toxicity, low residue fungicide that does not pollute the fruit.

4.The key is to seal the bag tightly and not to crush the fruit stalk. The young fruit should be placed in a bulging paper bag**, not close to the wall of the bag. The bagging is first up and then down, from the inside to the outside, to prevent leakage.

5.Advantages of bagging: improve quality, reduce the level of pests and diseases, reduce pesticide residues, mitigate and prevent natural disasters, etc.

It can be bagged, and there are many benefits of bagging, which is larger than if the child grows, and can avoid some pesticides, insects, etc.

After the peach is bagged, it will enter the fruit expansion period, which is the key period to determine the yield, and we must pay attention to timely watering and fertilizer, so as to promote fruit expansion and flower bud differentiation, and increase yield.

The fertilizer used is generally selected, 45% nitrogen, phosphorus and potassium controlled-release fertilizer + biological organic fertilizer + according to the digging of radiation ditch 8 10 cm deep, each fruit tree needs to dig 6 fertilization ditches to apply, do not apply fertilizer too shallow, too concentrated in one place, to prevent volatilization, loss, root burning, after the bag, then apply fertilizer, do not delay the fertilization time because of soil drought, if it rains better after fertilization, pay attention to the weather forecast when fertilizing, there is no rain in recent days, and a small amount of water should be watered after fertilization, In order to facilitate the use of fertilizers.

Calcium supplementation: The demand for calcium fertilizer accounts for 70% of the year during the expansion period, calcium supplementation can reduce the occurrence of bitter pox, reduce fruit cracking, brighten the peel, and improve the quality and storage resistance of fruits.

Magnesium supplementation: Magnesium supplementation enhances photosynthesis and chlorophyll content, ensuring the need for fruit enlargement. Magnesia deficiency trees showed different degrees of green loss between leaf veins and boron supplementation

Entering the fruit expansion stage, reproductive growth is vigorous, as an important nutrient in this stage, boron plays an important role in the rapid increase of carbohydrate transport and fruit formation.

Potassium dihydrogen phosphate supplementation: potassium dihydrogen phosphate can enhance photosynthesis, promote the transport of photosynthetic products, and is conducive to fruit expansion, coloring, and sweetening. This topdressing can effectively accelerate the rapid expansion of fruit and increase the expansion rate of fruit cells.

It plays an important role in improving yield, overcoming the "size year" of the tree and promoting flower bud differentiation.

After the peach is bagged, it is time to expand the fruit, and fertilizer should be supplemented in time to promote the peach expansion.

Fruit set fertilizer. After flowering to before hard core application, the purpose is to promote fruit set and early fruit expansion, fruit setting fertilizer is mainly nitrogen fertilizer, and add a small amount of potassium dihydrogen phosphate in fertile leaves, the amount of fertilization accounts for 10% of the annual fertilizer amount, generally 5-10 kg of urea per mu, or 11-28 kg of potassium bicarbonate. For very early and early maturing varieties, more potassium dihydrogen phosphate should be applied to the fertile leaves.

Fruit-promoting fertilizer is applied after the rapid growth of the fruit again after the hard core, and 22 kg of urea or ammonium bicarbonate can be applied per mu, or a certain amount of fertile leaf series water-soluble fertilizer can be applied per mu.

Nitrogen fertilizer was added after the fruiting period of peaches to enhance the tree potential. The potassium content in peach fruit is twice that of nitrogen, and the application of potassium fertilizer increases the yield of large fruits. Fruit-strengthening fertilizer was applied in the hard core period from late April to May, and potassium fertilizer was mainly applied for early-maturing seeds, and nitrogen fertilization, phosphorus accounted for 20%-30%, and potassium accounted for 40% of the whole year. Fruit picking fertilizer is applied before and after fruit picking, and the application rate accounts for 15%-20% of the year.

Peach bagging can not cover the peach tree, the peach tree is covered, the leaves can not carry out light and action, and the peach tree will die.

Extend. Bagging is a very important part of fruit tree planting, in addition to strengthening flower and fruit management, manual charges and thinning flowers and fruits, it is also necessary to do a good job of bagging in order to improve the color of the fruit surface, improve the appearance quality of the fruit, and protect the fruit in a targeted manner. The following is an explanation of the bagging technology of peaches for the reference of the majority of fruit farmers.

1. Advantages of bagging technology.

1.Improve the color of the fruit surface, make the background color of the peel neat and consistent, clean and bright, improve the appearance quality of the fruit, and increase the yield is obvious.

2.It can reduce the harm of peach borer, Tsubaki, peach heartworm, pear heartworm, leaf roller, brown rot and anthracnose, avoid flies and bird damage during ripening, and improve the rate of good fruit.

3.Avoid direct contact between pesticides and fruits, reduce pesticide residues, and improve the safety of fruits.

4.Prevent the burning and cracking of the fruit.

5.Reduces the red pigment in the flesh to promote uniform ripening and improve quality.

Due to the high humidity and serious pests and diseases in the southern peach producing areas of China, the bagging technology should be vigorously promoted, while the northern producing areas should be mainly applied to medium and late maturing varieties.

Second, the time and method of bagging.

2.The principle of bagging: first set early and medium-ripening varieties and varieties with high fruit setting rate and not easy to drop fruit on the branches, and then set varieties with low fruit setting rate.

3.Bagging skills: Bagging should be carried out in the order of branches from top to bottom and from inside to out. The mouth of the bag is connected to the slow branches, and the hemp skin and lead wire are tied tightly to build a mold, and the special paper bag has embedded about 3 cm of lead wire on the bag (from the Internet) when making.

Answer: Peach bagging is not to trap the peach tree, peach bagging can only trap the peach, the peach tree is also trapped, which is not conducive to photosynthesis and lead before the clear can not absorb favorable water!

1. Prepare a 2-liter vinegar bucket (or soy sauce bucket); 2. The height of the front of the barrel is 12 cm, and the back edge is 16 cm cut with a blade; 3. Cut off the top of the small plastic medicine bottle, put in the sponge, pour in the spring kernel glycerin as the intermediate potato quality when rubbing the bag, and screw the medicine bottle on the side of the vinegar barrel with a thin wire (left and right, choose according to personal habits); 4. Cut 1 hole on the left and right behind the vinegar barrel, thread into the long cloth strip, and the simple bagging tool is completed. 5. Prepare glycerin, skin care product base oil, to prevent pickpockets from digging up old skin, barbs, cracks, moisturizing, and can assist in holding bags more conveniently.

Peaches can be bagged, especially some late-maturing varieties with large fruits, which need to be bagged more. The main function of X0D X0A peach bagging is to prevent the infection of pests and diseases, improve the quality of fruits, and reduce pesticide residues. For some late-maturing varieties, due to the long growing season, summer is very susceptible to pest infestations, resulting in a loss of commodity value.

Through bagging, the invasion of pests can be blocked, and the rate of fruit damage can be significantly reduced; Moreover, when spraying, due to the barrier of fruit bags, the liquid medicine will not touch the surface of peaches, thus reducing pesticide residues. In addition, the skin of the bagged fruit is uniform and thin, so it will not be exposed to sunburn, and the color is uniform after the bag is removed, which can significantly increase the proportion of high-quality fruits.
