Fine soil preparation for sticky corn planting techniques
(1) The depth of the bottom fertilizer can reach 25 cm or more and is easily absorbed by the roots of the crop, thereby improving the utilization rate of the fertilizer. At the same time, after the deep application of the farmyard fertilizer, it can be decomposed in the deep layer of the soil, and activate the deep soil microorganisms, which is obvious to the improved soil. effect.
(2) The autumn base fertilizer is beneficial to protect the soil moisture. After the autumn fertilizer is applied, the soil porosity is increased, the water holding capacity in the field is increased, and the winter and spring preservation effect is good.
(3) It is conducive to the preservation of seedlings. Because of the application of fertilizer in autumn, most of the chemical fertilizers are turned into the deep and middle layers of the soil. The amount of surface chemical fertilizer is reduced correspondingly during spring sowing, the concentration of chemical fertilizer around the seeds is reduced, and the seed emergence rate is increased, which is beneficial to preserve seedlings. .
(4) Enhance the lodging resistance of crops, the root development of crops has a strong fertility, and the combination of deep base fertilizer in autumn and shallow base fertilizer before spring sowing makes the fertilizer evenly distributed in the middle and lower layers of the soil, which is beneficial to the vertical and horizontal crops. stretch. The root system is developed, the water absorption and fertilizer absorption capacity is strong, the crop resistance to lodging and drought resistance is significantly enhanced, and at the same time, the early defermentation and premature aging of the crop is effectively prevented, and the effect of increasing yield and income is significant.
(5) Alleviate the time of the farm, use the deep-rooted fertilizer in the autumn, and relieve the labor shortage in the spring.

Feline Infectious Peritonitis (FIP), referred to as Feline Infectious Peritonitis (FIP), is a fatal abnormal immune response that occurs in cats. It is caused by the mutation of the feline coronavirus carried by cats. As a high-incidence and fatal disease of pet cats, the current incidence of feline abdominal transmission is about 10%.
The symptoms of cats are usually divided into two categories, namely wet FIP and dry FIP, of which wet FIP accounts for the majority of all cases. About 70%, manifested as abdominal pleural effusion, abnormal bulging; dry FIP cats have different symptoms, depending on the type of organ affected by the virus.
So far, all feline feline feline treatments are based on the characteristics of the disease, and GS-441524 can play a role in the treatment of feline feline disease. Therefore, the therapeutic effect of GS-441524 is obviously more ideal, the dose used is less, the treatment cycle is shorter, and the efficacy, safety and convenience of operation are all good. Because of this, GS-441524 is considered by many pet owners and veterinarians to be a magic medicine that can effectively treat feline abdominal infection.
