First, grafting summer pruning to remove large branches on the back, leaving 4 to 6 new shoots in the canopy near the trunk, making it breathless, grow robust. Grafting time began from August 20 to September 20, prematurely prone to flow, too late to too low temperature is not easy to survive. The opportunity to miss the opportunity in the autumn can be grafted when the spring buds are just sprouting. The method of grafting uses buds with xylem buds. Two buds are grafted on both sides of each tree. After being grafted for one month in the autumn, the buds are unwound. In the spring, when grafting and binding, the buds are exposed. As long as no overflow marks are formed, they do not need to be untied.
Second, the plastic trim pruning spring snow Peach is strong, dry and weak, the most appropriate use of "Y" shape pruning, tree potential ease, simple pruning, high light transmittance, easy to color the fruit. Before germination, 1 cm cutting anvil is left in the upper part of the grafted shoots, and the remaining branches are all cut off. After sprouting, buds other than budding are promptly wiped to ensure normal growth of budding buds. When the buds grow to about 10 centimeters, they are picked up to make the shoots lignify as soon as possible, which can reduce the windbreak loss. In late August, the branches were pulled diagonally to a 45-degree angle. The branches could not bend, bow, or tilt. During the winter pruning, the back branches were removed, the heads were competed, and the dense branches were lengthened. The oblique branches and oblique branches were left, and all the branches were not short cut.
Third, the soil and fertilizer water management to promote the formation of the crown as soon as possible, in late May and late June, respectively, applied 150 grams of urea, in late July, the plant 100 grams of diammonium phosphate, 150 grams of compound fertilizer. During the growing season, the sprayed fertilizer was sprayed once every 15 days, and 0.3% urea was sprayed in the early stage, and 0.3% potassium dihydrogen phosphate was sprayed after 7 months. When the soil moisture is insufficient, it will be watered in time. In September, basal fertilizer will be used. Each mus will be sterilized with 5,000 kg of chicken manure and 50 kg of special fertilizer for fruit trees. After fertilizing, it will be watered and the frozen water will be poured before winter.
Diseases and Insect Pest Control The local diseases and pests mainly include peach bacterial perforation, aphids, red spider, leaf leaf moth, and pear borer. Controlling aphids can be done with 10% imidacloprid WP or wormworm 1500 times liquid, from June to July spraying 50% carbendazim WP 600 times + 25% diflubenzuron 3x SC 2000x , Prevention and treatment of peach bacterial perforation, leafminer, leaf leafworm, etc., especially pay attention to the damage of peach small carnivorous, once the knuckle will destroy the tip of the new advantages of the shoot, will cause multi-head competition after re-germination, is not conducive to the "Y" shape Pruning. The control can be used to spray 1000 times the new tip of the high efficiency cypermethrin.
Fifth, flower and fruit management to promote the prosperous new shoots into flowers, in mid-August on the new shoots sprayed 200 times paclobutrazol, 10 days later if not capped, can be sprayed again. The fruit rate of Chunxue peach is high. In order to improve the quality of fruit and ensure high yield, it is necessary to carry out manual fruit thinning. The fruit thinning is generally carried out 10-15 days after flowering, generally 3-5 fruits are left in the long fruiting branches, and 2 fruits are in the middle fruiting branches, and the fruit spacing is about 15-20 cm.
At present, the heat metering market commonly used heat table is divided into mechanical heat meter(mechanical heat metering) and ultrasonic heat meter.The mechanical heat meters is consist of temperature sensor, flow sensor and calculator. With the aid of the temperature sensor, The mechanical Heat Meters measure the inlet water and return water temperature. Flow rate sensor measures the volume rate of the hot water in the tube trough the time difference. The figures recorded will be delivered to integral calculator which calculates the total heat and displays.
The mechanical heat meters sensors measures the flow rate through the circles of the wheels. According to the specification, The DN can be ≤40mm and ≥50mm. According to the inner structure, the small size mechanical heat meters can be single jet and multi jet. At present, our mechanical heat meters belong to single jet mechanical heat meters and they have higher request from the water quality. According to the counter of the flow sensor, the mechanical heat meters can be dry and wet type. Our mechanical heat meters are the dry type.Except mechanical heat meters,the plastic heat meter is also a good product.
