1 Reasonably selecting the site: The site must be selected from the soil that is not polluted, away from the factories and mines, along the highway, clean air, no water pollution, deep soil, fertile soil, sandy ground construction site with low groundwater level, as in the vicinity of factories and mines There should be no sewage, smoke and dust emission companies at the park, upstream, and upwind outlets. The environmental conditions of the site are the preconditions for pollution-free production and the basis for the pollution-free production of grapes. If the site is selected in the contaminated environment or close to the pollution source, pollution-free production cannot be discussed. 2 Moderate dense planting: The key to pollution-free production is to reduce the pollution of fruits. In addition to pollution, the air, water, and soil determined by the environment, the most important pollution comes from pesticides, fertilizers, auxins, etc., and is suitable for close planting. The creation of suitable environmental conditions for the growth of grapes can reduce the incidence rate, ensure the robust growth of plants, reduce the application of chemicals such as pesticides, chemical fertilizers, and auxin, and reduce pollution. If the colonization density is too large, the population growth in the field is large, and the demand for chemical fertilizers increases. The field tends to close, the pests and diseases increase, the amount of pesticides increases, and the pollution will increase. Therefore, attention should be paid to the proper close planting in the production, and the principle of dipping and diluting should be mastered to reduce the degree of chemical pollution. It is usually planted at 40.5-1 m spacing, and 170-333 mu per plant are suitable. After the growth, the number of plants is gradually reduced. 3 Reasonable watering: The environmental conditions of grape growth and dryness, and high air humidity, can lead to major pests and diseases, increase the frequency of drug use, and increase pollution. Generally, during the period of germination, fruit expansion and winter soil freezing, the grapes need a large amount of water. During these critical periods, the supply of water should be ensured. In addition, when the drought is severe, it should be based on soil moisture and plant growth at any time. Watering. Pollution-free production water must be clean, heavy metals and pollutants in the water can not exceed the standard, generally require mercury <0.001 mg / kg, cadmium <0.05 mg / kg, arsenic <0.1m mg / kg, lead <0.1 mg / kg, volatile phenols < 0.1 mg/kg, cyanide <0.5 mg/kg, oils <1 mg/kg. 4 Reasonable fertilization: Fertilizer should be adhered to organic fertilizer. Fertilizer should be applied 3 to 5 times a year, supplemented by chemical fertilizers, and organic fertilizers should be fully decomposed. In particular, human feces and urine and medical waste that are not cooked must not be used. About 5000kg is applied as base fertilizer. When applying chemical fertilizers, attention should be paid to controlling nitrogen, increasing phosphorus and potassium, appropriate zinc supplementation, and applying proportionally. Generally, nitrogen, phosphorus and potassium can be applied in a ratio of 1:0.7:1. Because phosphorus and potassium fertilizers are delayed fertilizers, they are used in soils. In the long decomposition time, the absorption and utilization of grapes is slow, and 80-85% of the basal fertilizer should be applied, and 15-20% of the basal fertilizer should be applied during fruit expansion. Nitrate can not be applied to nitrogen fertilizer, 30% can be applied as basal fertilizer, and 70% can be applied as topdressing fertilizer. Nitrogen fertilizers are usually urea and diammonium phosphate. Phosphate fertilizers are mainly applied to calcium superphosphate and diammonium phosphate. Potassium fertilizers are mainly applied to potassium sulfate, and zinc fertilizers are mainly foliar sprayed, spraying 3% zinc sulfate before germination. supplement. 5 rack type selection: In the rack type selection, it is not only conducive to increase the ventilation and light transmittance in the field to control the occurrence of diseases, but also conducive to the improvement of fruit quality, but also to meet the characteristics of varieties, thus in the rack type to choose In consideration of overall consideration, it is generally based on hedgerows, and large-grained and large-spike varieties such as Red Earth, due to the propensity for sunburn, use small horizontal scaffolds and have a good effect. When pruning on the fence wall, no branches are left within 50 cm from the ground. The results of the mother branch are selected up to 1.5 m, and the auxiliary tip is left at the upper 0.5-1 m to increase nutrition. Ventilation and light transmission reduce the occurrence of pests and diseases, which in turn contributes to the stability of production and the robust growth of trees. 6 to strengthen the management of dendrite growing season: the grape has strong branching ability and can easily sprout secondary shoots, which leads to deterioration of light, which is unfavorable to pollution-free production. Therefore, in the production, the management of branch growing season should be strengthened to effectively control the amount of field branches. After germination, timely eradicate the bud system 10-15 cm to distinguish the inflorescence, remove the young shoots, carry out the sprouting steps of latent buds, too dense and too weak shoots, wiping every 5-7 days, scaffolding Eight to ten new shoots per square meter are left, and a new shoot is left on the fence 10-15 centimeters. The branches and branches in the flowering, left in the inflorescence leaves 5-6 leaves topping, development branches left 8-10 leaves topping, vegetative branches and apical leaves left 3-4 leaves topping, the results of axillary shoots left 1-2 leaves topping. In the growing season, the vines shall be tied in time, and the vines shall be fixed on the plane in order to occupy a reasonable space and ensure the ventilation and light transmission within the rack. 7 Strengthen flower and fruit management: the pollution-free grape produces fruit with high requirements, requiring complete and typical ear, uniform fruit size, full maturity, good coloring, strong flavor, small number of defective fruit, high soluble solid content of fruit, Low pesticide residues. Production should pay attention to strengthen the management of the ear, in the flowering period according to the vegetative branch, the result branch 2:1 proportion to sparse vegetative branches of the inflorescence, pay attention to the age of the branches, according to the species left ear, like the red earth 3-4 years old trees remain 8 -10 spikes, 5-7 years old trees left 10-12 spikes, 8 years old or more trees left 13-16 spikes, pay attention to sparse spikelets, densely squeezed ear, diseased ear, and deformed ear, remove the retained inflorescences. The spikes near the rachis and the long ears. In the process of fruit growth, pests and granules, small grains, squeezing grains and deformed grains were removed. During ripening and harvesting, the diseased fruits, cracked fruit grains, small grains and poorly colored fruit grains were removed. 8 fruit bagging: promotion of fruit bagging, reduce the occurrence of pesticide pollution and sunburn disease, generally around 20 days after anthesis, when the size of soybeans in the fruit when no wind and no dew cloudy days, 8000 times before bagging Fuxing +2000 times liquid to spray the whole plant, until the liquid is dry, then bagging, picking the bag in the first half of harvest, in order to facilitate fruit coloring. 9 Pest Control Pest prevention and control should adopt comprehensive prevention and control methods, focusing more on the application of Agriculture, physics, and biological methods. It is necessary to strengthen the work of clearing the garden, timely cutting out diseased leaves in the field, controlling the amount of branches in the field, preventing the deterioration of light, and suppressing the occurrence of diseases and insect pests. Manual killing, black light, sex attractant, sweet and sour liquid trap and kill pests. Use ladybugs, grasshoppers and thrips to control the occurrence of field pests and minimize the use of pesticides. For chemical control, pesticides should be low-toxicity, low-residue pesticides, and the use of high-toxicity and high-residue pesticides should be prohibited. In the pollution-free production, when the pesticide is applied, the mineral source and the biological source should be the main source. Diseases mainly include prevention and control of Bordeaux mixture, lime sulfur, solibar, carbendazim and chlorothalonil. Insect pests are mainly treated with diflubenzuron 3, pyrethroid pesticides, anti-indolazole, and zizatin.
