September apple orchard management
In September, ripe varieties of apples ripened one after another, and the trees entered the late growth period. The management points of this period were as follows: I. Timely harvesting of mid-maturing varieties of apples is an important condition to ensure the quality and storage of apples. Early harvesting, inadequate apple development, poor coloration, light weight, poor flavor, intolerant storage; late harvest, apple has reached the peak of breath, storage capacity greatly reduced. Marshal is the apple should be harvested in early September, at this time the appearance of the apple luster, coloring is good. Golden Delicious apples should be harvested in mid-September, when the fruit surface yellow-green background. Picking is generally carried out in the order of the upper part of the crown of the lower part of the canopy and the inner part of the crown of the outer part of the first canopy. The result should be protected and the bad branches and bumps should be avoided. Second, soil and fertilizer water management September should be strengthened in apple orchard cultivating loose soil, in order to maintain loose soil, good ventilation, and create a good soil environment for root growth and development. The basal fertilizer should be applied in time after harvesting the medium-harvest apple varieties, so that it can be partially used in that year. At this time, the roots are the third peak of the root growth. Because the roots of the base fertilizer damage are easy to produce callus, they also play a role in the root system. Pruning can also promote new roots. Basal fertilizer is mainly composed of fully decomposed organic fertilizers, and appropriate amount of quick-acting fertilizers or fruit tree-specific fertilizers are added. The amount of fertilizers accounts for 60% to 70% of the total amount of fertilizers in the year. Young apple trees apply 2000-2500 kg of organic fertilizer per acre, plus 20 kg of urea and 80-100 kg of superphosphate; Apple trees over 5 years old apply 4000-5000 kg of organic fertilizer per acre, plus 40-50 kg of urea and 100 ~150 kg of superphosphate. Take ring groove and strip groove fertilization. In the ring-shaped groove fertilization, dig 40-50 cm deep and 40-60 cm deep in the ring groove at the outer edge of the canopy, mix the back and the soil with a ratio of 1:3, then cover the soil; The size of the canopy is fertilized in rows of apple trees, between plants, or in rows of 40-60 cm wide and 40-60 cm deep, and watered immediately after fertilization. After medium-harvest apple varieties were harvested, 0.5% potassium dihydrogen phosphate and 0.5% urea were sprayed on the leaves for 10 to 15 days to increase the photosynthetic function of the leaves and delay the defoliation. In September, we must do a good job of drainage and flood prevention to facilitate apple coloring and improve the appearance quality. Third, the apple late-maturing variety management In late September, the bagging of red Fuji and other late-maturing apple varieties to carry bags, picking leaves, transfer fruit, silver gray reflective film and other work. In order to promote the coloring of the apple and achieve full redness, the shaded leaf near the bagged apple is removed at the same time when the outer bag is torn open. The leaves of the fruit and the leaf within 5 cm from the apple are picked first, and after 3 days, other shading blades are picked. 10 days after bag removal, when the apple's positive surface has been fully colored, gently lift the apple by hand and rotate 90 to 180 degrees so that all parts of the apple are fully exposed and evenly colored. Picking leaves and turning fruits should be carried out on cloudy or cloudy days. Sunny weather should be carried out after the temperature drops at 4 pm. Conditional apple orchards shall be provided with a silver-gray reflective film under the canopy immediately after bagging to promote the coloring of the pods and the lower apple and apple pods in the tree body, and at the same time, the branchlets shall have good light and full flower buds. In addition, attention should be paid to properly removing the dense branches on the outside of the crown and the upright branches on the back, the long branches on the inside, and the sprouting branches of the saw cut.
