How to do a good job of clearing fruit trees in winter to ensure that the output will increase in th

Winter garden cleaning is an important part of the annual management of fruit trees. The quality of the garden is directly related to the pest control base in the following year. Therefore, fruit farmers attach great importance to the work of clearing fruit trees in winter.

So, how do you clear your fruit trees?

Based on years of production practice, Qingjiang Crane recommends:

First, winter shear shaping: <>

The extension branches of the main branch are shortened to maintain the advantage. Then remove some of the large branches that affect the shape of the tree, and the long branches. If the number is large, it can be cultivated as auxiliary branches.

When pruning, pay attention to the main branches, side branches and fruiting branches, and the hierarchy should be clear.

Second, scrape and treat rot disease, branch blight and pear psyllid spot and other overwintering pests and diseases. <>

Rot disease occurs mainly on the main stem or large branches. The base of the trunk often appears as a dead tree due to bark decay. The pathological tissue should be scraped off during the winter tube, and the affected area should be smeared with a mixture of 70% methyl and vegetable oil to prevent scarring**.

Then use a brush to clean the eggs and insect residue that remain on the tree.

Three, clean up the orchard: <>

Remove the waste, diseased branches, diseased leaves and fruits left by winter pruning in the orchard, and clean up the dry weeds in the orchard, and burn the overwintering insect eggs and bury them deeply.

Fourth, wound treatment: mainly insect mouth treatment and winter shearing and sawing treatment. It is generally made with wax and rosin oil mixture.

When preparing, the wax will be dissolved, and then alcohol and rosin oil will be added and stirred evenly, and the clear oil ingredients can be increased or decreased according to the weather conditions, so that the application is neither coagulated nor lost.

5. Application of stone sulfur mixture: the whole park is treated with stone sulfur mixture for insecticidal and sterilization spray. Reduce the number of pathogenic bacteria and insect pests in winter.

Finished stone sulfur mixture can be used, or quicklime can be used to make self-made stone sulfur mixture. The quality of lime should be good, flour can be added to play a sticking role, and vegetable oil can also be added to moisturize and prevent oxidation.

Sixth, tree cold protection: use self-made whitening agent or finished whitening agent to whiten the base and trunk of the fruit tree. The concentration of the whitening agent is limited to the extent that it does not flow down and does not stick to the pimple, and it is appropriate to stick a thin layer on the tree and be uniform.

In winter, you should remove all the dead branches and fertilize the land.

Thoroughly sweep the orchard of debris. Fallen leaves, weeds, dead branches, stiff fruits, is one of the main wintering places of pests and diseases, these debris must be cleaned out of the orchard when clearing the garden, deep burial treatment, or burning, manure, only by removing the overwintering pest habitat, eliminating the overwintering pests and diseases on the dead branches and leaves, in order to reduce the base of orchard overwintering pests and diseases.

Plants should be pruned in winter. Prune off some of the old yellow branches, and also give the plants regular nutrients and water, so as to ensure that the yield can increase in the coming year.

In order to be able to bear more results in the second year. Cut off the excess and keep the nutrients in the trunk so that it can bloom and bear fruit more the next year.

So the correct measures to clear the garden is what we all have to refer to now to the season of clearing the garden, a lot of work can be carried out, today mainly talk about two aspects, the effect of clearing the garden, the method of clearing the garden and the period one, the effect of clearing the garden, the so-called clearing the garden, is to clean the orchard before and after the dormant period of the fruit tree, in order to eradicate overwintering pests and diseases, reduce the number of pests and diseases in the growth period of fruit trees, reduce the occurrence of pests and diseases in the growth period of fruit trees, into the late autumn and early winter, the vast majority of fruit tree pests, pathogenic bacteria began to die on the branches, dead fruits, fallen leaves and bark cracks, Weeds, dormant in the soil, overwintering, dormant.

After the fruit tree enters dormancy, its resistance to pesticides increases. Diseases and pests in the dormant state of overwintering are concentrated in wintering places, and the ability to resist pesticides and activities is poor. Therefore, by taking advantage of the characteristics of the vast majority of pests and pathogenic bacteria dormant and overwintering in dead branches and leaves, diseased insects and dead fruits, bark cracks, weeds, soil, etc., measures such as trunk bunching grass, scraping old warped bark, whitening, dealing with sawing edges, winter ploughing, spraying pesticides and other measures are taken to carry out a comprehensive prevention and control of orchard pests and diseases.

In order to do a good job in the management of fruit trees in spring, it is necessary to prune and prune the leaves of the fruit trees, and remove the weeds in the orchard.

In the spring, the orchard should do a good job of weeding, and in the spring, everything recovers, and the weeds will grow in large quantities, competing with the fruit trees for fertility, so we must weed in time.

Make regular rounds and carefully inspect the trees. If there is a problem, it can be dealt with in a timely manner. It's also a little more reassuring.
