The giant winter peach, also known as red snow giant peach, is one of the largest winter peach varieties in China. Its fruit sugar content is as high as 19.6%, and its maturity period coincides with Mid-Autumn Festival and National Day holiday. Therefore, it has been favored by fruit farmers and consumers in recent years. Worth promotion. 1. Characteristics of the variety The fruit of the variety is nearly circular, with an average fruit weight of 400 grams. The background color is milky yellow, and the fruit surface is more than 60% bright red. The pulp is milky white, crisp and tender, sticky nucleus and extremely sweet. The fruit is extremely resistant to storage and transportation and can be stored for more than 35 days at room temperature. This species has a strong growth potential, stands upright in trees, short in internodes, and easy to form flower buds. The rate of self-inflorescence production is as high as 41%. The rate of strains grown in the second year after planting and planting is 100%, and the yield in the third year can reach 18 kg. After four years, it will enter a period of abundant production, yielding up to 4,000 kilograms of fresh fruit per mu. Second, colonization specifications for the capture of high yield, should adopt the dwarf close planting cultivation. Flatland and slope soil planting specifications to 3 meters 1 meters is appropriate, mus planted 222. The colonization holes are 80 cm in length and 60 cm in depth. The inside of the hole is filled with crop stalks, soil miscellaneous fertilizers, etc., so that a layer of fertilizer is layered and the soil and fertilizer are mixed. The top cover is 30 cm thick soil. The best time for planting was from September to November and from February to March of the following year. Third, fertilizer and water management In winter, peach trees planted in the spring will be topdressed for the first time after germination, and will be topdressed once every 15 days. Each time, nitrogen, phosphate fertilizer and organic fertilizer are used to apply water to the soil. The top sentence in July stopped cultivating fertilizers to control shoots and prosperous growth, which is conducive to flowering. In late September, the decomposing manure, livestock and manure water is applied once. The second year in February, July, late September and early May each application of compound fertilizer, in early March is the initial stage of flowering, in case of drought should be timely watering drought to facilitate flowering. During the high-temperature season from May to September, it is used as straw or weeds to cover tree trays to provide drought-resistant moisturizing, which is beneficial to fruit enlargement. In rainy season, drainage should be drained in time to prevent waterlogging and create a suitable environment. Fourth, plastic trim V-shaped ventilation and light transmission is good, early results, high yield and stable production. Methods: 40 to 50 cm short-stemmed and left in the year of colonization, and 2 Zhuang branches that are selected to stay in the line between the lines are selected as the permanent main branch. The main trunk is not left, and two bamboo sticks are inserted obliquely to fix the main branch. 45 degrees to the ground. Another 4 to 6 shoots were used as ancillary cultures. When they were 30 centimeters long, they took toppings and twisting tips to promote flowering and fruiting the following year. After the high-yield period, the auxiliary branches will be gradually removed. The main branch at 40 centimeters took off the heart to promote branching, and at the same time selected the top Wang shoots for the extension branch, and tied it to the diagonally inserted bamboo raft. In the second year of pruning, short cuts were made to the extension branches to promote branching and to select extension branches. The tree is shaped for two to three years. The length of the main branch and extension branch is about 1.5 meters, and a 0.6 meter translucent zone is maintained between the rows. Fifth, flower and fruit management This species is very easy to flower, self-bake strength, physiological fruit drop and light fruit before harvest. The thinning of fruit is carried out from late May to early June, and the ratio of leaf to fruit is maintained at 50:1. Implementation of bagging can prevent pest damage and cracking, but also significantly increase coloration and improve quality. Bagging was carried out after fruit thinning in early June, and bags were unpacked in mid-September. 6. Spray insecticide and bactericide before and after pest control bagging; spray 3 to 5 degrees lime sulfur to prevent leaf shingle before germination; spray rate killer liquid to control aphid in early April; spray from early May to early June The mancozeb solution or carbendazim solution prevents bacterial perforation, powdery mildew, and scab, etc.; from July to August, it kills leafminers and other insect pests by killing the lipid solution.
