Cucumber production to grasp the "four fit"
Moderate retention
Judging from the current market trend, the market should accept cucumbers that are straight, 25-30 cm long, and 2.5-3 cm thick. If there are too many melons, there will be big melons, melons, melons, melons, melons, and melons that are too long or too short. From the market point of view, these melons have no interest, and they are treated at extremely low prices. Defective goods. Therefore, in order to focus on nutrient production of high quality cucumbers, sparse melons are necessary.
Moderately picked leaves
The removal of old leaves and diseased leaves should be a management task that is often carried out in the cultivation of cucumbers. Cultivation of greenhouses and greenhouses is indispensable. In the production, some vegetable farmers think that the more leaves are picked, the better the field permeability, the more melons are harvested, and even the functional leaves are removed. This is wrong. Practice has proved that: The leaves are the providers of melon nutrients, too few leaves, the melon will grow slowly and small. Therefore, the fact that picking leaves off will result in a reduction in the “source†of nutrient production, which will affect the enrichment of product “librariesâ€.
Moderate fertilizer irrigation
Cucumbers require large amounts of water for fertilizers, especially when they enter the period of melon growth. Fertilizers should be supplied in a timely manner. Otherwise, they will shorten the period of nectarine and lead to early decline of production. However, excessive fertilization and irrigation will cause great waste, pollute groundwater sources and even cause soil salinization. Fertilization and irrigation will affect yield. The method of "eat less and eat more" should be used to apply fertilizer and irrigation to overcome the blindness of fertilization and irrigation. Each fertilization, irrigation volume should not be too large, but it can be carried out frequently.
Moderate spraying
At present, some vegetable farmers use large doses of medicines, whether they are prevention or prevention, and some are even 1-2 times higher than the required concentration. Finally, the diseases may be controlled, but the leaves are also damaged. The light leaves are aging, and the heavy leaves are distorted. Deformation, production capacity is greatly reduced, because the damage caused by phytotoxicity is sometimes greater than the disease caused. Mixing several kinds of pesticides that are different in nature but can be mixed together can be used to achieve a multiplier effect and prevent excessive concentrations from causing phytotoxicity.

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.
