Correctly exposing the grass and grasshoppers is extremely important for the production of vegetables in winter greenhouses. Here, to remind the farmers, lay bare grass and grass should pay attention to science:
First, in the morning, I have asked many vegetable farmers in the past: What is the basis for exposing the grass in the morning? The answer is very consistent: When the sun shines on the shed, it is revealed. To what extent did you expose it? Most shed farmers cannot answer it. Should use the shed gas? The magnetic unloading administer also punish the bad æ°– 涫 涫 涫 窈 窈 窈 窈 ã„Š ã„Š ã„Š ã„Š ã„Š ã„Š ã„Š ã„Š ã„Š ã„Š ã„Š ã„Š ã„Š è† è† è† è† è† è† è† è† è† è† å³¤ 峤 峤 峤 峤 峤People have to summon to play????

Second, in the afternoon, the grass cover farmers in the afternoon cover the grass and grasshoppers in a variety of situations, and some of them are covered by the sun, some covered in the afternoon from half past three to four, in fact, this is not science, should be based on the temperature within the shed Determine the time for covering grasshoppers. The method is: When the temperature in the shed reaches 17~18°C, the grass cover will begin to cover. After the cover is covered, the temperature in the shed may increase, and the temperature rise may not exceed one degree. Emphasizes that air temperature is related to the transport of organic matter at 17~18°C. The plants produce organic matter through photosynthesis and are manufactured during the day and transported to the various organs of the plant (roots, stems, leaves, and fruits) at night. When the greenhouse is covered with haystacks, the stomata of the crops are closed, and transportation begins. The transport speed is directly related to the greenhouse temperature. In the case of 17-18°C, 7-8 hours are completed, and if the temperature is lower than At 15°C, it will take 15 to 16 hours to reach the end of the journey. The organics that have been transported to Sarawak must be transported until the next night. The warehouse will not be vacated and will directly affect the production of light and products on the second day. The output has a great influence.
Third, the long-lid suddenly clear uncovering the grass and grass for a long time low temperature rain and snow even sunny days after a cloudy day, do not open all the grasshoppers to prevent "flash seedlings" (a few days of rain and snow did not uncover the grasshoppers, shed crops did not see the light The leaves are thin and tender, sunny days and strong light, and large amounts of transpiration cause the leaves to lose water and wilting. In the first three days, the flower buds should be exposed (every time one or two are exposed), the area opened up gradually. After two days, all are uncovered (the shed can be opened first, then gradually increased).
Active Pharmaceutical Ingredients
Active Pharmaceutical Ingredients(API) refer to the raw materials used in the production of various preparations. They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly. API is intended to be used in any substance or mixture of substances in the manufacture of pharmaceuticals, and when used in pharmaceuticals, it becomes an active ingredient of the pharmaceuticals. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, treatment or prevention of diseases, or can affect the function or structure of the body. According to its source, active pharmaceutical ingredients are divided into two categories: synthetic chemical active Pharmaceutical ingredients and natural chemical active Pharmaceutical ingredients.
