What are the factors that affect the quality of fruit trees? What can be done to improve fruit quali

pests and diseases, sun exposure time, watering frequency, fertilizer use; Do a good job of water and fertilizer management, do not water and fertilize on rainy days, and let fruit trees bask in the sun more.

Temperature, light, moisture, fertilizers and environmental conditions all affect the quality of the fruit. When the flower buds of fruit trees are differentiated, appropriate drought can promote the flower bud differentiation and early flowering, and try to artificially remove flowers and fruits during flowering and fruit set, so as to prevent the lack of nutrients in the tree due to uneven nutrient distribution, resulting in the phenomenon of large and small years, and bagging it after the fruit grows.

The termination of the fruit tree is related to the selection of fruit seedlings. The environment in which the fruit is grown is also important, and choosing the right environment can improve the quality of the fruit. When planting, it is necessary to choose the corresponding seedlings.

It can also be pollinated manually, which can improve efficiency and make pollen evenly pollinated. Fruit trees are managed during the planting period. The management will include fertilizer spraying, etc.

The main measures to improve the quality of fruits are as follows.

1) Strengthen soil management.

Do a good job in the basic construction of orchards so that the soil structure is good. Attention should be paid to soil and water conservation, horizontal terraces, hole expansion, deep soil transformation, reasonable drainage and irrigation, cultivation and weeding, and good permeability of the soil.

2) Scientific fertilization and increased application of organic fertilizer.

Pay attention to the application of basal fertilizer in autumn, advocate planting green manure in the tree tray and between the rows, and pay attention to increasing phosphorus and potassium fertilizer. Nitrogen fertilizer is usually applied in the early stage of growth, and phosphorus, potassium fertilizer and compound fertilizer are mainly applied in the later stage, and nitrogen fertilizer is strictly controlled.

3) Reasonable irrigation to ensure timely and effective supply of water.

Especially in the critical periods such as flower bud differentiation, flowering, and fruit expansion, the effective water should be ensured.

4) Do a good job of artificial assisted pollination during the flowering period.

Strong thinning of flowers and fruits to work, overcoming large and small years.

5) Do a good job of covering the ground with reflective film.

For example, for red-skinned pears, this is conducive to fruit coloring and increasing the solids content, thereby improving the quality of the fruit.

6) Timely insect prevention and treatment.

The focus is on the prevention and control of early defoliation diseases such as pear scab, pear large solid worm, pear small heartworm, pear psyllid, scab and brown spot disease.

7) Artificial bagging cultivation can be implemented in rainy areas.

to improve the appearance quality of the fruit.

8) Timely harvesting.

When the fruit develops to the inherent size and color of the variety, it should be harvested in time to increase yield and ensure quality.

1. Boron spraying during flowering.

Spraying boron during flowering can effectively improve fruit set. Generally, the borax solution is sprayed once at the beginning of flowering.

2. Artificial pollination.

Artificial pollination during the flowering period has a very obvious effect on improving the pollination rate of fruit trees.

Third, pay attention to sparse flowers and fruits.

Flower and fruit thinning of fruit trees is to adjust the number of trees with dense flowers and fruits to make their load appropriate.

For fruit trees with many flowers, many fruits, and high fruit setting rate, the inflorescences should be thinned from the overly dense cluster of flower branches.

Varieties with more fruit set should be more sparse, and varieties with less fruit set should be sparse. Fruit trees are thinned, generally leaving 2 fruits for each fruit branch and 1 fruit for bagging fruit trees.

Fourth, spray urea after flowering.

The growth of fruit trees consumes the nutrients stored in the tree, and it is necessary to supplement nutrients in time to reduce physiological fruit drop and increase yield, generally spraying urea solution once about 10 days after flowering, which has obvious effects on promoting the growth of fruit tree branches and leaves and reducing the second physiological fruit drop.

Fifth, the auxiliary branches are peeled in a ring shape.

Annular peeling of auxiliary branches also has a good effect on reducing flower and fruit dropping, but it is necessary to pay attention to and master the ring peeling of trees.

Master only on the auxiliary branches of their own flowers, the ring peeling mouth should not be too wide, generally to the branch thickness of 1 8 1 10 is appropriate.

For young trees that have not yet flowered, ring stripping is also an effective measure to promote flowering, and it should be mastered to carry out ring stripping before flowering.

If the ring stripping is for the purpose of flowering, it should be done before the new shoots of the fruit tree stop growing.

It can make the imitation quality of the fruit better, make the fruit sell higher, increase the yield of the fruit, improve the sales of the bridge, and increase the income.

It can help the development of agricultural products, increase the output of agricultural products, increase the sales of agricultural products, and increase the income of farmers and make farmers develop better, all of which play a role in the quality of agricultural and sideline products.

It can make the yield of fruits higher, the quality of fruits can be better, the price of fruits can be improved, the fruits can be protected, and the output of sales can be increased.

Do not prune at will, prune off diseased branches and dead branches, and try to prune small branches to prevent bacterial infection caused by excessive wounds; Be sure to cut lightly and slowly, and also pay attention to the different methods of summer and winter cutting, in addition to choosing some shaping methods that are suitable for the shape of the tree.

It is necessary to pay attention to the way of pruning, but also to the protection of fruit trees, to pay attention to the process of pruning, to pay attention to the length of pruning, and to pay attention to the pattern of pruning.
