In the growth and development of crops, in addition to the absorption of a large number of elements such as NPK, it is necessary to provide a specific amount of micro-fertilizer. For autumn sowing crops, zinc fertilizer is applied to wheat, boron fertilizer is applied to rapeseed, molybdenum fertilizer is applied to bean crops, selenium is applied to garlic, and even if their demand is relatively small, it is indispensable. If the lack of boron in rapeseed will cause "flowers and unreal" and increased glutinous grains, the lack of boron in radish will cause hollowness, the lack of boron stalks in cauliflower will cause cracking, and the lack of molybdenum in green manure will lead to poor growth of nodule. The following methods can be used to apply micro-fertilizer, which has a very good effect on the high yield of autumn-sown crops.    I. Soaking method    First, the micro-fertilizer is diluted with water, and then the seed is placed in the micro-fertilizer solution, so that the seed absorbs the fertilizer and expands, and the fat enters the seed with the water. Therefore, in the process of soaking seeds, it is necessary to turn the seeds from time to time so that the seeds can be uniformly absorbed into the fertilizer.    Second, the seed dressing method    First, use a little water to dissolve the relevant micro-fertilizer, and prepare it into a very high concentration of fertilizer. Then use a clean sprayer to spray the fertilizer onto the seeds, spray half a mixture, and apply a layer of fertilizer to the surface of the seeds. Usually, only 1 to 4 grams of micro-fertilizer is used per 0.5 kg of seed , and it can be sown after the seeds are dried.    Third, the soil method    In the sowing of autumn crops, the micro-fertilizer 0.5 kg to 1.5 kg and seeds are planted into the seeding ditch. If the amount of soil is sufficient, it can be supplied to the crop for the whole growth period. Practice has proved that when the amount of micro-fertilizer is large, the content of micro-nutrients in the crop is relatively large, because the micro-fertilizer is easily fixed by soil particles in the soil, the amount of use is large, and the investment is relatively high, so it should be used as concentrated as possible. Reducing the micro-fertilizer that is lost in the season, not only in the season or in the current year, but also can continue to achieve good results for many years, so the soil application method is suitable for economic conditions, and farmers with less labor can apply.  Features: Outdoor Led Module,IP65 Module Light,110V Led Module Light,RGB LED Module Light,Led Module With Lens Shenzhen You&My Electronic Technology Co., Ltd , https://www.youmyledlight.com
