What are the applications of sustainable spray in the agricultural industry
The core of sustainable spray is to reduce resource waste and environmental impact through correct control, efficient atomization and other technologies. It is widely used in agriculture around crop life-cycle management, covering multiple key links such as pest control, nutrition supply and environmental regulation, and adapts to different planting scenarios and crop types. The specific applications are as follows:
1. Proper prevention and control of pests and diseases in various scenarios
This is its most core application, which can solve the problem of pests and diseases in different planting scenarios in a targeted manner, and significantly reduce pesticide loss and pollution. For example, in Jiangxi Gannan Navel Orange Garden, Hainan Areca Planting Area and other orchards, UAV sustainable spray enables the liquid medicine to penetrate the canopy of fruit trees with the help of atomization technology, correctly cover the fruits and branches, reduce the amount of pesticides and improve the effect of pest control; In Jiangsu rice area, electrostatic spray technology can make the fog droplets electrified, so that the back of the lodging rice straw can also be attached with liquid medicine, and the effect of controlling rice planthoppers and other pests is good. In facility agriculture such as vegetable greenhouses and seedling bases, the electric sustainable spray can spray disinfectant regularly, evenly cover the enclosed space, control the spread of bacteria, and avoid the large-scale spread of diseases and pests; Before planting, specialized disinfectants can be sprayed onto the soil to kill residual bacteria and insect eggs, laying a solid foundation for crop sowing.
2. Correct nutritional supplementation throughout the entire crop cycle
Sustainable spray can adapt to the application of different nutrients, such as foliar fertilizer and nutrient solution, to meet the needs of different growth stages of crops. For field crops such as wheat and corn, during key periods such as jointing and grouting, plant protection UAVs or guided agricultural machinery equipped with a sustainable spray system can spray foliar fertilizer according to crop growth variables. When the speed is fast, the spray volume will be increased automatically, and when the speed is slow, the spray volume will be reduced to avoid fertilizer waste; For Yunnan flowers, greenhouse vegetables and other crops with high nutritional requirements, trace element nutrient solution can be sprayed correctly by adjusting the size and concentration of spray droplets, which can meet the growth needs, and will not cause seedling burning or soil fertilizer accumulation due to excessive nutrition. In some scenarios, pesticides can be mixed with foliar fertilizers and sprayed correctly, achieving dual effects of insect prevention and fertilization in one operation, improving planting efficiency.
3. Regulation of growth environment in facility agriculture
In greenhouse, greenhouse and other facilities agriculture, sustainable spray is an important means to control the environment. In summer, when the temperature is high, water mist is continuously sprayed into the shed through the fine mist spray system. Water mist evaporation can quickly reduce the ambient temperature, prevent crops from wilting due to high temperature, and maintain a certain air humidity, which is suitable for the growth of wet crops such as leaf vegetables and flowers; In winter, the greenhouse is highly airtight and the air is dry. Proper spray can supplement the humidity to prevent crop leaves from drying out due to water loss. In addition, in some seedling breeding bases, sustainable spray can be combined with disinfectant to carry out all-round atomization disinfection of the seedling breeding environment, reduce the probability of seedlings being infected by bacteria, and improve the survival rate of seedlings.
4. Auxiliary planting management of special crops
According to the growth characteristics of some special crops, sustainable spray can provide customized planting assistance. For example, in the cotton planting area, if the seedling stage encounters a cold wave of low temperature, the cold resistant agent can be sprayed through sustainable spray, so that small droplets can be evenly attached to the surface of cotton seedlings, and enhance the cold resistance of cotton seedlings; In the planting base of traditional Chinese medicine, such crops have strict requirements on pesticide residues and growth environment. With the advantages of low dosage and high accuracy, sustainable spray can strictly control the amount of pesticides and fertilizers and meet the green planting standards of traditional Chinese medicine. In addition, for crops that need to be ripened or kept fresh, an appropriate amount of ripening agent and fresh-keeping agent can be sprayed through sustainable spray, and the dosage can be controlled correctly to avoid the influence of pesticide residues on quality.
5. Postpartum auxiliary treatment to reduce losses
Sustainable spray is also applied after crop harvesting to help ensure the post harvest quality of agricultural products. For example, after the fruits and vegetables are harvested, the sustainable spray system can be used to spray fresh-keeping aerosols that meet the food safety standards on the surface of fruits and vegetables to form a thin protective film, reduce the water loss of fruits and vegetables, delay oxidative deterioration, and extend the storage and transportation period; Before storing grain, sustainable atomization disinfection of the storage environment can kill mold and pests in the warehouse, prevent mold and decay during grain storage, and reduce postpartum losses.
