The damage to crops is seriously jeopardized, resulting in a decline in the yield and quality of the crops and the loss of farmers. Find the right pesticides in a timely manner. Xiaobian recommended to everyone effective prevention measures, as follows:
Qiling is a broad-spectrum, contact-killing acaricide that can be used to control a variety of plant-borne mites, and is effective for the entire growth process of mites, from eggs, cubs, nymphs to mites. Another advantage of this medicine is that it is not affected by temperature changes, and it can achieve satisfactory results in early spring or autumn.
Qiling has obvious control effects on plant-eating pests such as spider mites, whole-clawed scorpion, and small-clawed scorpion. According to the pesticide manufacturer , it is mainly suitable for citrus, apple, pear, hawthorn, cotton, tobacco, vegetables (except eggplant) and ornamental plants. For the control of citrus and apple red spider, pear and hawthorn, etc., it can be applied during the occurrence of the disease. (To improve the control effect, it is best to use 2~3 heads per leaf), 20% The wettable powder or 15% emulsifiable concentrate is diluted with water to 50~70mg/L (2300~3000 times). Lingling 15% (Emulsion) products have ultra-fine treatment, high suspension rate, good adhesion, resistance to rain erosion, and no cross-resistance with common acaricides.
Pesticide Network ( ) Tips: The safety interval is 15 days, that is, the drug is stopped 15 days before the harvest, and the crop can be used up to 2 times per season. I hope these methods can avoid the loss of farmers' friends.
Nitrogen generation by Pressure Swing Adsorption (PSA) process is a technology used to separate nitrogen from a mixture of gases under pressure according to the special selective adsorption characteristics of the Carbon Molecular Sieves (CMS).
The Carbon Molecular Sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases. When the pressure is high enough, the oxygen molecules, which pass through the pores of CMS much faster than the nitrogen molecules, are adsorbed, while the coming out nitrogen molecules will be enriched in gas phase. The enriched oxygen air, adsorbed by the CMS, will be released by reducing the pressure. Then the CMS is regenerated and ready for another cycle of producing nitrogen enriched air.
