Fertilizer management In winter, the fruit trees are applied with 50 kg of manure, 10 to 15 kg of bean cake, 5 to 10 kg of superphosphate, and 5 to 10 kg of manure from 1 to 2 years old plants. The method is to open two symmetric grooves or circular grooves 1 to 1.5 feet deep under the drip line of the canopy, and cover the fine soil after seepage. In the case of drought, the leaves are withered and should be irrigated every 5 to 10 days, depending on the size of the fruit trees and the degree of drought. Generally, irrigation in the canopy soil layer is appropriate. Soil management (1) The frozen soil is turned over. In winter, the soil in the garden is deeper than the canopy drip line, and it is 1~1.5 feet deep. The wintering pests, weeds, roots and seed soils are frozen to prevent soil compaction; the soil is shallowly ploughed; the disc on the tree is 2~3 inches. . (2) Clean up the orchard and remove impurities. After the winter, we must remove all the fallen leaves, weeds, vines and other sundries from the garden, and burn them intensively to remove the pests and disease areas in the winter. (3) The trunk is whitened. After the winter, all the fruit trunks are combined and trimmed, and all of them are whitened with lime water to prevent the pests from overwintering in the trunk.

Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.
