First, the law of occurrence, the best period and method of prevention and treatment 1, the ground spraying and exterminating adults. From late April to mid-to-late May, adult emergence emerges. About 7 days prior to this, the ground was sprayed on the orchards that were seriously damaged in the previous year and the places where pomegranates were piled up. Each bucket of water was mixed with 3 dimethoate or 2 Chestnut to kill the soon-to-be-exposed adults. . Can also be applied per acre 15% Losbian granules 1 kg, or sprayed on the ground 1.5% Puller suspension 100 ml fleas and kill the first feathered adult. 2, canopy spray to kill the adults before spawning. The period from early June to July is the period of adult emergence and spawning, which is a critical period for crown spraying. The first is to uniform spraying time, according to the height of the altitude in the adult early stage of spawning in late May or early June spraying. Every 7-10 days, spraying until late July, spraying at an altitude of 400 meters above the ground until early August. The second is to formulate a unified formula, can use traditional methods: use two trichlorfon 1, brown sugar 3 kg plus 100 kg of water to one-third of the canopy and 1 meter of orchard around the weeds to spray killing. Or implement a new method: First, use a special fly-fighting agent for fruit fly control, 1 bottle per acre, 1.2-1.6 pounds per bottle, spray with a hand-held sprayer, or 2-3 meters between the points, or 1 1:15 "fly flies" diluent hanging bottles or bowls to kill; second is the use of Yidu food flies produced by the big fruit fly: one bag per mu (200 milliliters) of the attractant, adding "all spirits" (or "extinction" Duowei ") 5 grams of water powder 2-3 kilograms spray part of the orange tree (only 5-10 per acre spray) leaves, depending on the amount of field insects spray interval 10-15 days for the second time, a total of three times; 3. Remove the killed fruit to kill the larvae. August-September is the larval stage. From the beginning of July, young fruit that has been spawned will be removed as soon as possible, cut open or boiled to kill larvae. After entering September, the hazardous fruit was removed and put into a film bag. Each bag was filled with 100-200 times of dichlorvos or 200 millilitres solution of dipterex into the bag to seal it, or immersed in the bag for more than 2 days before being buried deeply. Second, the main production area protection Cut off the route of transmission. All production areas should strengthen the prevention and control of deadly and sporadic orchards, and adopt universal joint defenses between villages and villages and between households and households so that villages are not leaked, households are not leaked, and gardens are not leaked. Prevent the spread of channels such as ditch river valleys and trading venues. The removed fruit (including the victim fruit) must not be piled up at will, and must not be thrown into the ground, roadsides, and creeks. The river should not fall into the ground and be destroyed. Remove as much as possible from the tree to prevent the larvae from becoming mature. Wintering. Ponkan is strictly prohibited from entering the market. Black Goji Berry is rich in protein, fat, sugar, free amino acid, organic acids, minerals, trace elements, alkaloids, vitamin C, B1, B2, calcium, magnesium, copper, zinc, manganese, iron, lead, cobalt, nickel, cadmium, chromium, potassium, sodium and other nutrients. Been scientifically tested that the content of calcium, iron, niacin is respectively 2.3, 4.6, 16.7 times of red Goji Berry, especially procyanidins than blueberries(Black goji berry contain procyanidins is 3690 mg / 100 g; blueberries contain procyanidins is 330-3380 mg / 100 g). This is the highest ever discovered procyanidins content of natural wild fruit, which is the most effective natural antioxidant, its efficacy is 50 times of VC and 20 times of VE, the vitamins, minerals and other nutrients content is also higher, medicinal and health care value is much higher than ordinary red Goji berry, known as "soft gold".
