Pruning the spring branches is beginning to spring. Fruit farmers have to do the work of plastic tree pruning, and adjust some branches and flowers. The reason for this is because the temperature rises in early spring, and fruit farmers can clearly distinguish leaf buds and flower buds. For young fruit trees, strong trees or branches should be left, while weak trees or branches should be left. For the fruit trees that are being transformed, it is necessary to comprehensively use measures such as branching, engraving, turning, and ring cutting to promote the balance and stability of the fruit trees as soon as possible. After the tree germinates, wipe the buds and shoots in a timely manner, wipe off the buds and shoots with poor growth angles according to the requirements of plastic surgery, and thin out the clumps, overdense branches, and long branches.
The prevention and control of spring insects and early spring is the key period for the control of fruit tree diseases and insect pests. Fruit farmers must control the disease and insect pests during this period. Before sprouting, clearing the garden can effectively eliminate a variety of overwintering insects, eggs and germs, reduce the source of infestation, and reduce the wintering base of the pests. After being stunned, pruning again in conjunction with early spring to remove the winter overwraps that attract insects at the root and neck of the trunk, remove the overwintering pest cocoons on the branches, clean the litter, litter, weeds, and fallen fruit in the orchard and focus on deep burial. Or incineration. When chemical control is used, the spraying operation can be performed with 34% pyrite mineral oil 1000-1500 times the liquid; spraying should be even and thorough to ensure that no spraying or re-spraying is maintained to maintain the healthy growth of the fruit tree.
The application of spring fertilizer in early spring requires a large amount of nutrients for the growth of early spring fruit trees, so in order to thrive, the fruit farmers should apply fertilizer. If the fertilizer is not applied in time, the shoots will grow badly and the flowers and fruits will be severe, which will affect the fruit yield and quality. Therefore, fruit farmers should apply a quick-acting fertilizer, mainly nitrogen fertilizer, before supplementation based on the previously applied base fertilizer, and supplement a large amount of nutrients consumed by the tree body according to the actual situation. The amount of topdressing varies depending on the orchard situation. Before apples, pears, peaches and grapes bloom, persimmon trees and walnuts should be topdressed in time during flowering. For orchards with poor fruiting or lack of pollination trees, pollination should be done well. Fruit trees with good fruiting performance can be properly pollinated during flowering, and the excess flowers should be properly thinned out, which is conducive to saving nutrients and improving fruit setting rate.
Suitable watering spring fruit trees require large amounts of water before and after flowering. Watering before flowering is conducive to fruit tree flowering, new branch growth and fruit setting, and watering after flowering can alleviate the growth of new shoots and young fruits competing for water, and avoid a large number of fruit drops. After the water seepage, the saplings can be used to cover the tree sap of the young trees in time, which can increase the ground temperature, protect the moth, and promote the coordinated growth of the fruit trees.
