Wupi Cherry is a high-quality, high-yielding, good-quality cherry from the local cherry in the Banan District of Chongqing. With large particles, purple, high sweetness, no cracking fruit. Good product characteristics. Usually two months after the planting of the grafted strong seedlings, it can be put into production; entering the full fruit period, the yield per mu can reach more than 1,000 kilograms and the income is more than 8,000 yuan. Its high yield cultivation techniques are as follows:
First, the establishment of the park to plant a leeward sunny, deep soil or flat slope to build a park. First of all, set the line at a fixed point of 2.5m X 4m, and dig deep (or blast) the planting nests (pits) that are 1 meter wide and deep, and apply it to garbage, human and livestock manure, calcium superphosphate, etc. Fertilizer about 100 kilograms, and layered backfill soil sink. After defoliation, the seedlings were planted before sprouting in spring and 66 trees were planted in acres. Results Five years later (cutting) was shifted to half, leaving 33 permanent trees. Within 1-2 years after planting, for the young branch feeding period, every year from 2 to 8 months, apply once-a-month rotting water and fertilizer, apply 8-10 kg per plant, and add urea (or ammonium phosphate) 0.1 kg to facilitate pumping. Tips to expand the crown.
Second, the fertilizer management Wupi cherry planting two years into the results of the period, the whole year should be fertilized three times. First, apply enough basic fertilizer. Each year in the fall from September to October, 25 kg of water, fertilizer, and 1-2 kg of oil cake (blight) fertilizer, 0.2 kg of urea, and 0.5-1 kg of superphosphate are applied to each plant for composting. Second, timely fertilizer. The first application of fertilizer should be applied in mid-January. Each plant should apply 30-50 kg of water fertilizer and 0.2 kg of urea to promote the growth and flowering of spring shoots; the second fertilizer should be treated with phosphorus and potash fertilizers before and after fruit collection. The plant applies 30kg of manure and 0.5kg of multi-phosphorus potassium compound fertilizer or 0.2kg of potassium sulfate plus 1kg of superphosphate to promote fruit enlargement and increase yield and quality; once again, extra-root fertilizer is applied from the stage of sucking. Before deciduous, spraying 0.1% of Green Fenwei foliar fertilizer or 0.2% of potassium dihydrogen phosphate and 0.3% urea on the crown every 15 days or so will benefit the flowering result.
Third, the plastic pruning Uchi cherry generally use natural round head shape (or plexiform shape). The method is: cultivating 3-4 main branches and their large, medium, and small fruiting branch groups; for auxiliary branches, upright branches, and large branches, opening the branches in the summer to open the angle, timely picking the hearts of the new shoots for the internal malleolus, increasing The number of middle and short branches; when cutting in winter, the upper part is sparsely cut and the lower part is cut short, so as to improve the illumination and promote the growth and development of the inner litchi; the aged and weak branch groups that have been for many years are properly retracted and rejuvenated.
Fourth, pest control and prevention hazards The main pests and diseases of cherries include Sangdang worm and peach tumor plague. Thorn moth, pear borer and anthracnose, plastic gum disease. Comprehensive prevention and control measures should be taken. In winter pruning, the wells are burnt and destroyed. At the same time, in the deciduous period, the spraying of Baume 5 degrees lime sulfur once; before the spring shoots stop long, spraying 40% dimethoate 1200 times plus 70% thiophanate-methyl 800 times once; 7-8 spray 50% marathon Emulsion 1000 times plus 65% 400 times 500 times.
5. Maintaining stable fruits During the bud stage and flowering stage of the cherry, two sprays of 0.2% boron fertilizer and 0.2% potassium dihydrogen phosphate are used to spray the fertilizer. Afterwards, the spray is sprayed 2-3 times and 0.15% of Fenway Foliage is sprayed. It is an important measure to keep the fruit steady. In addition, spraying the 15% PP333 wettable powder 800-1000 times liquid can effectively inhibit the growth of new shoots and promote the formation of flower buds.
