Apricot trees are deep-rooted fruit trees and grow in sandy loam with thick soil and loose structure. However, almond trees in our area are mainly distributed in mountainous areas, and the soil is thin and has low fertility. Apricot soil improvement and field management in the fall are particularly important and directly affect the apricot yield.
First, fertilization apricot garden fertilization methods are mainly soil fertilization and top dressing. The extra-root topdressing is usually in early spring and growing season, and soil fertilization is carried out in combination with deep turning in the fall, so it is better not to be late. The first is the use of radial grooves, centered on the trunk, starting at 1/2 of the tree plate, digging 6-8 radial grooves outward, 30-50 cm deep, deep inside and outside shallow, and the length of the ditch exceeds the circumference of the canopy, and then in the ditch Fertilization. The second is to use a ring groove, 40-70 cm around the perimeter of the canopy projection, dig an annular groove, 40-50 cm deep, and apply the fertilizer to the trenches. The third is the use of ribbon gutters, this method is mostly used in larger orchards, in the periphery of the crown projection, can be used to mechanically open the ditch, depth 40-50 cm, the fertilizer applied to people buried in the ditch.
Second, the irrigation of apricots on the water is not high, the general young forest irrigation 4-5 times a year. Spring irrigation is required before sprouting to increase spring water use efficiency, reduce soil temperature, delay germination and flowering of apricot trees, and avoid early spring frost damage; pre-winter irrigation before winter freezing can ensure good growth of apricot roots in winter and spring, and significant Improve the cold resistance of flower buds.
Third, shaping and trimming
1. In the mountainous area, the shape of multiple main branches is used for shaping, and the result is directly formed on the main stem. The formation is rapid and the result is early. Through many years of introduction and cultivation, the canopy naturally grows as a round-headed evacuation shape, easy to plasticize, small amount of pruning, rapid formation, early results, dry height of about 60 cm, the whole tree choose to leave 5-6 main branches, the main branches of Shanghai 40-60 cm, choose to leave one lateral branch, leaving 2-3 lateral branches for each main branch.
2. Pruning Saplings Pruning In addition to the first and second years of fixed and short cuts, the medium and long branches can be dumped without cutting, and the main extension branches should be trimmed to about one third each year. Strong and strong branches can be recut. Promote two or three branches before releasing. Pay attention to reasonable load during pruning period, increase flowering branch, short fruit branch and bouquet-like fruit without cutting. The dense and short-cut middle and short branches may be thinned according to the principle of weakening and retaining strong, and three sets of branch groups may also be used for pruning to avoid Size year.
Fourth, the prevention and control of rodents
1. Use the autumn to clean up the weeds in tree trays and tree trenches and deepen them. At the same time, artificial baits were used where rats were found. Irrigation once before winter freezing can also play a role in rat prevention.
2. Artificially assist in protecting the body against rodents. 1 Using lining sleeves: Cut the linoleum 40-50 cm high and 30-40 cm wide. On the ground of the apricot tree, make a cylinder with a diameter of 5-7 centimeters. Use two thin wires to close the ground. The soil is buried. This method is small, simple, and can be used for 3-5 years. 2 Use mouse-proof membrane: cut the plastic film to a size of 39-40 cm and wrap it in the ground of the apricot tree. Close the ground and bury the soil. This method is simple and easy to use, but it is short-lived and must be loose every spring. 3 Mineral water bottle pedicles: Cut off the shoulders and bottom of the water bottle, cut it upright, and put it directly on the stem of the trunk. Close the ground to bury the soil. 4 Rat-proof net: Set it directly on the stem of the trunk, and place the man near the ground.
3. Protect natural enemies, breed and protect domestic cats and other animals to eradicate rats.
