1. Rational fertilization, irrigation, fertilization and irrigation are important technical measures for fruit production in greenhouses. The intensive cultivation of fruit tree facilities requires a high supply of fertilizer and water. Practice has shown that increasing organic fertilizers, applying chemical fertilizers properly, and properly watering can promote robust trees and dark green leaves, which can significantly reduce pests and diseases. The tree vigor is weak and the leaves are malnourished. The damage to the pests is heavy. In addition, some greenhouse fruit trees, such as peach trees, are extremely resistant, and they must be drained in time during the rainy season. 2, a reasonable pruning, cutting pests and branches pruning is an essential technical measure in the production of fruit trees in greenhouses. Pruning, in addition to regulating the contradiction between vegetative growth and reproductive growth of fruit trees, achieves the goal of early results and early high yield, it also has a certain positive effect on pest control. When cutting in winter, you can cut off branches and spots that are endangered, such as the mullet. In summer, new shoots and diseases and insects can be removed by removing pests and fruit, cutting off aphids, and punching holes. The branches, leaves, and fruits that have been cut off are collected and taken out of the shed to be destroyed. 3, removal of many bacteria such as perforating disease litter debris, overwintering in the diseased branches, diseased leaves or diseased fruit; some pests such as peach leaf miner and other wintering in the deciduous; some pests on the branches wintering, such as brown Caterpillar eggs, etc. Therefore, after the fruit trees are fallen or cut in winter, the cut branches and leaves should be destroyed. 4, timely removal of the fruits of the ground pests and fruit damage by carnivores, often fall off in advance. Before the young fruit has not been detoxified, it should be promptly picked up and concentrated. This is an effective method for controlling fruit pests. 5, Artificial insect traps, such as suspended animation, clustering and other habits. These pests can be used to carry out artificial control. 6, trapping adult insects 1 sweet and sour vinegar trap adult insects kill many adults, such as roll leaf insects, borers, and pink neck beetles, etc., on the sweet and sour liquid has a strong tropism, with sweet and sour liquid can trap a variety of pests. 2 black light traps adult pests such as peaches and wild horses, etc., have a strong tendency toward black light, black light traps can be set. 7, the ground application of certain pests, such as Lee small borers, have winter habits in the soil. After larvae or adults emerge in the winter, or after the larvae have fallen into the soil, the pesticide is applied to the ground to eliminate most of the pests. 8. Canopy Spraying Canopy spraying is the main method used in the prevention and control of pesticides in fruit crops in greenhouses. The following principles should be mastered: 1 Selecting the best spraying period: The occurrence of each pest has its sensitive period to pesticides, such as Prevention and control of caterpillar pests, spraying the larvae during the incubation period and young larvae, can get twice the result with half the effort. For diseases, prevention and control effects are better during the period of disease transmission or initial spraying. 2 to be targeted: Before each spraying, it should be clear which pests are the main control objects, which are both the subject of treatment, so that the type and concentration of medication can be determined to avoid waste. 3 reduce the blind use of drugs: the harm caused by pests on fruit trees is only shown when there is a certain population, can not see pests and spray. In this way, human and material resources are often wasted. In order to avoid this phenomenon, we must make predictions based on pest and disease prevention and control indicators. 4 Alternating use of pesticides: Continuous use of the same pesticide can lead to pest resistance and reduce the control effect. At this time, fruit growers tend to increase the dosage. This will not only increase the cost of prevention but also aggravate environmental pollution. Practice has proved that the alternative use of pesticides with different mechanisms of action will not only reduce the number of injections, but also increase the effectiveness of control and prolong the life of pesticides. 5 Pesticide mix: In the production, pest control is often mixed pesticides and fungicides, or mixed two pesticides. When pesticides are mixed, it is necessary to find out which pesticides can be mixed and which pesticides cannot be used together, and they must not be arbitrarily mixed. Otherwise, there will be pesticide failure or drug injury. 9. Remove diseased plants for prevention and treatment of virus diseases and similar diseases on fruit trees, such as peach latent mosaic disease, grape leaf disease, leaf rolling disease, strawberry mottle disease and wrinkle leaf disease, etc. Currently, there is no effective treatment. The method that is practicable is that if a diseased plant is found, it should be removed and destroyed. 10. Cultivation and planting of virus-free seedlings The most economical and effective measure for the prevention and control of virus diseases and similar diseases on fruit trees is to cultivate and plant virus-free seedlings.
