Transformation Technology of barren Jujube Orchard
The main results are as follows: (1) Deep ploughing of broken board, famine and tiller can remove weeds, remove redundant tillers and seedlings, and increase soil permeability and the ability of storing water and melting fertilizer. And can turn the eggs and larvae of pests to the surface to die or pick out the table to kill. Deep ploughing should be carried out when the soil is suitable for ploughing. Too dry or too wet is easy to form bumps and break the structure. Deep flip should also master the depth of adaptation, the far crown area should be deep, up to about 20 cm, and the near crown area should be shallow, about 10 cm. So as not to hurt the roots too much and affect the tree. Deep turning creates for the re-growth of the root system.

Occurrence and control of pear gibberella
The adult began to Eclosion in late April and bit a flat round hole in the first and middle of May. The adults feed on the leaves during the day after coming out of the hole, and lie still on the leaves sooner or later, and have the habit of falling to the ground and false death. The adult began to lay eggs in about 10 days after coming out of the hole, and the trunk crawled at the front of the oviposition. The ovipositor was inserted into the rough and warped gap of the bark to lay eggs. Most of the eggs were laid in the branches of more than 2 years old, 3 eggs were laid in one place, and each female could lay 40 eggs. The peak spawning period is in mid-late May and the peak incubation period is in early June. The hatched larvae first eat into the cortex.

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

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" shape pruning is dominated by lateral branches (the main branch angle is 70 degrees to the left.

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.

Jujube gall midge
Distribution and host this insect belongs to the order Pteroptera, Culicidae. Distributed in Hebei, Shaanxi, Shandong, Shanxi, Henan and other jujube producing areas. The hosts are jujube tree and wild jujube tree. The harm and symptoms are that the larvae suck the juice of jujube or sour jujube buds and leaves and stimulate the mesophyll tissue to make the injured leaves roll longitudinally to the leaf surface. The injured site changed from green to purplish red, hard and brittle, soon blackened and withered, and there were often several heads and even larvae in a roll of leaves. Morphological characteristics 1. The adult female is 1.4mm to 2.0mm long; the compound eye is black, reniform; touching.

Storage and fresh-keeping Technology of fresh Peach
1. Frozen peaches are vulnerable to freezing injury during low temperature storage, and there is a risk of freezing at-1 ℃. Therefore, the suitable storage temperature of peach is 0 ℃, and the suitable relative humidity is 90%-95%. Under this storage condition, peaches can be stored for 3-4 weeks or more. However, when the peach is stored at low temperature for a long time, the flavor will gradually fade, and the long-term cold storage will cause freezing injury and browning of the flesh, especially when the peach is ripe in the high temperature environment, the pulp will become dry, spongy and soft, and the pulp around the core will be bright.
