Management Technology of Apricot in greenhouse
1. Fertilizer and water management. No fertilizer was applied after plastic film mulching, and 0.3% urea plus 0.2% photosynthetic micro-fertilizer and 0.3% potassium dihydrogen phosphate were sprayed once after fruit-setting and hard-core stage. Drip irrigation pipes are installed in the shed to water reasonably according to the soil moisture. Watering should not be too much, lest the new shoots will flourish and cause physiological fruit drop.
two。 Shaping and pruning. "Y"-shaped pruning is mainly lateral branches, proper thinning or utilization of upper dorsal branches, long flat branches, retraction of drooping branches, cutting off dense branches, disease and insect branches and withered branches.
3. Artificial pollination. Due to the high humidity of the air in the shed, the pollen is not easy to spread, so a box of bees is put in the shed to pollinate or pollinate artificially.
4. Control of major diseases and insect pests. Spraying 700-800 times carbendazim 10 days after anthesis to control scab. Spraying 2-5 times methamidophos and omethoate before germination or spraying 4000 times imidacloprid and 2000 times fenvalerate after germination to control aphids and control almond bees. Before germination, 50 times engine oil emulsion plus 150 furan was sprayed to control shell insects.
5. Control of physical elements. (1) Light. Apricot is a light-loving tree species, and the light transmittance of the selected greenhouse film is better. Covering plastic film on the ground in the greenhouse can increase scattered light and meet the requirements of apricot trees. In cloudy days, the grass should also be properly opened to make full use of scattered light, and appropriate artificial supplementary light. (2) temperature. The temperature is required to be different in each growth stage, and the temperature should be gradually increased at the beginning of the greenhouse, not too fast; 15-22 ℃ in the day before germination, not less than 5 ℃ at night; 15-18 ℃ in the day, not higher than 23 ℃ in the day, and 7-8 ℃ at night; no more than 27 ℃ in the daytime and 5 ℃ at night during the fruit development period; during the day when the fruit is nearly ripe

A new yellow peach variety 'Golden Crown' for both canned and fresh food
The 'Golden Crown' (see Feng Sancai photo) is a superior line of yellow peach for canned storage and fresh food selected by the author from the natural hybrid of 'Jinxiu' yellow peach in the 1990s. After many years of regional experiments and production trials in Shandong and Jiangsu for many years, the character is stable and the comprehensive performance is excellent. It was identified by experts organized by the Science and Technology Department of Shandong Province in September 2006. The variety characteristic characteristic tree posture opens, the tree potential is strong, the sprouting ability and the branch forming ability are strong. Annual branches yellowish green, reddish near the base, and after entering the fruiting stage

Establishment of Kernel Apricot Garden
Apricot trees are fruit trees that like light, drought, waterlogging and frost, so they should choose sunny and dry places to build gardens, not on shady slopes, waterlogged depressions and valleys where cold air is easy to sink. Apricot is a long-lived fruit tree, generally-200-year-old trees are still rich, and the planned spacing between trees and rows is larger. However, considering the needs of early high yield, temporary plants can be set up at the establishment of the garden, and thinning or transplanting gradually with the increase of tree age. The plant spacing of the permanent row can be designed according to 4 meters × 6 meters, and the temporary encryption garden is 2 meters × 3 meters, which should be dealt with in time to about 10 years old.
