Six experiences of “low-carbon medicationâ€
The editor has been engaged in agricultural technology promotion work in Huaihai Farm of Jiangsu Province for nearly 30 years. He is well aware of the rational use of pesticides to increase the production and income of grain. The field is also a national high-quality commodity grain production base, and the prevention and treatment of rice in 80,000 mu of rice. In particular, it pays great attention to environmentally-friendly low-carbon drugs, thus fundamentally solving the food security problem and receiving good social effects. The editors now list their use of pesticides for your reference.
Uniform drug purchase: The purchase of bulk pesticides by the farm is purchased by the farm unified organization through the annual and current drug use plan of the farm agricultural technology department. To the qualified, reputable and powerful pesticide distributors, on the one hand, large-volume purchases have greatly reduced the cost of agricultural materials, while also ensuring the quality of pesticides and the characteristics of high efficiency, low toxicity and low residue, thus not Pesticides that are safe for food use are kept outside the farm.
Measuring and selecting drugs: The farm has established a pest monitoring and reporting station, established a three-level plant protection and protection patrol network on the farm, and established a pest and disease intelligence sharing mechanism with surrounding farms and villages to find out the specific time and quantity of each batch of rice pests and diseases. And the degree of harm, and then through analysis to determine whether to use drugs, the variety and concentration of various liquids, and through the farm units to establish a farm machinery and plant protection team to quickly control the completion of limited time to extinguish, to achieve the purpose of unified defense.
Tolerance: For each pest in the rice field, by analyzing the time, quantity, distribution, natural enemies and degree of damage, if the cost of prevention is higher or higher than the yield loss caused by no pest control, Abandon medication, reduce the number of medications used in the field, and reduce the cost of medication and food production.
Limiting cultivation: It is to promote the rice varieties resistant to (resistant) diseases and pests, to regulate the fertilizer varieties at the various stages of rice application, the rhythm of the application, and various physical, mechanical and biological measures in the field, especially in the early stage of rice planting. Through the promotion and cultivation of resistant (resistant) pest rice varieties, the enthusiasm pests are trapped to eliminate or pass through cultivation, reducing the number of other field pests, achieving the purpose of saving the drug and effectively preventing and treating diseases.
Insect-free application: Through the practice of cultivation for many years, the majority of scientific and technical personnel on the farm input the concept of low-carbon medicine, such as “control insects, insects, hatching, pest controlâ€, among the management cadres and workers, which is the occurrence of pests and diseases on rice. Before the severe damage, the young pests are not resistant to drugs, and the sensitive period of weak resistance to pesticides is eliminated. That is, when the average person does not see the small or spotted state when the pests occur, the use of very few The purpose of the drug is to achieve high efficiency protection.
Space-avoiding: Before entering the peak season of rice in September or in the middle and late stages, the farm takes administrative measures to treat pests and diseases, and then maintains the efficacy by using long-acting and low-toxic pesticides. Afterwards, the ban is prohibited from applying in the rice field, so that the low-toxicity and low-residue pesticides that have accumulated and adhered to the rice leaves, plants or rice have sufficient time to attenuate and prolong the use of pesticides before rice harvest. The interval between the foods makes the food truly green and safe.
When viewed from indoors privacy film doesn't look dark. From the street, film looks very similar to bare glass. Apply the Projection Smart Film in a dust-free, well-lit, shaded place. Apply the tint when the air temperature is between 40 and 98 degrees Fahrenheit (4.4 and 36.7 degrees Celsius). Be careful not to crease the Projection Film. Wet your fingertips to avoid getting fingerprints on the Magic Film.
Intelligent atomized glass is used as doors and Windows: it can be used by remote control or automatic control to determine whether the doors and Windows are transparent. When the sun is fierce, atomization can be controlled to make the light soft. The whole room area is comfortable and beautiful, without losing the effect of light transmission, and the position of the curtain can be removed. Intelligent atomized glass can be used as a projection curtain wall: in transparent state, it can display the decorative picture of the background, or as the glass wall of the conference room. In opaque state, it can replace the curtain. There is no need to install the curtain device on the glass wall.
