Four key points of apricot management technology in greenhouse
1. Fertilizer and water management. Base fertilizer is applied every autumn. Base fertilizer is mainly livestock manure, compost, cake fertilizer and other organic fertilizer, properly mixed with some nitrogen, phosphorus, potassium fertilizer. After covering plastic film, fertilizer is no longer applied, and 0.3% urea plus 0.2% compound micro-fertilizer and 0.3% potassium dihydrogen phosphate are sprayed once after fruit setting and hard core period. 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。 Plastic surgery and trimming. The "Y"-shaped pruning is mainly lateral branches (the branch angle of the main branch is about 70 degrees). The upper dorsal branches are properly thinned or utilized, the mediocre branches are long, the drooping branches are retracted, and the dense branches, disease and insect branches and dead branches are cut off.
3. Artificial pollination. Due to the high humidity of the air in the shed, the pollen is not easy to spread, so it is necessary to put a box of bees 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. Apply 2-5-fold omethoate ring before germination or spray 4000-fold imidacloprid plus 2000-fold fenvalerate after germination to control aphids and control almond bees. Before germination, 50-fold oil emulsion plus 150-fold furan was sprayed to control scale insects.

Cold resistant cultivation techniques of Zizyphus jujuba
The cultivation of jujube in Liaoning Province is mainly concentrated in Chaoyang, Huludao and Jinzhou. In recent years, the high price of jujube, especially the high benefit of excellent new varieties, drives many growers in many areas to introduce and plant in large areas one after another, but most of them fail because of freezing injury. The newly developed areas are limited to Dalian and Yingkou, and the varieties are only pear jujube, Jinling jujube and so on. Other areas are still sporadic courtyard planting, and most of them are old varieties. In order to improve the development of jujube production in Liaoning Province, the author thinks that more attention should be paid to the cold-resistant cultivation of jujube. 1 cold-resistant varieties

Incidence regularity and control techniques of iron skin disease of jujube
Jujube iron skin disease, also known as fruit shrinkage disease, black rot, commonly known as fog scald, fog Liaotou, dry waist, black waist, iron coke, fire and so on, is a serious fruit disease of jujube. Since the early 1980s, the disease has become more and more serious. It begins before and after coloring, the disease is fast and concentrated, and it often breaks out. Many jujube producing areas, such as Hebei, Henan, Shandong, Shanxi, Inner Mongolia, Guangxi, Sichuan and so on, have occurred. In general years, the yield loss caused by the disease is 20%, 50%, and in serious years, the loss is up to 70%, 80%, and even appears.
