Misunderstanding 1: When fertilizing, it is close to the stem of the plant, and the fertilizer is easily absorbed. The part of the plant that absorbs nutrients is in the root hair area. The stems and roots of the plant (except the root hair area) absorb little or no absorption. When fertilizing, the stalks are close to the stem (except the seedling stage). The fertilizer is not easily absorbed, if too much fertilization If the concentration is too large, it is prone to "burning seedlings".
Misunderstanding 2: After the crops appear to be deficient, fertilize again. It takes 3-5 days for the fertilizer to be applied to the paddy field before it can be absorbed and utilized by the crop. The dry land generally takes 5-7 days. Therefore, if the crop is fertilized after the lack of fertilizer, the crop shortage time will be lengthened, resulting in a reduction in production. Therefore, the fertilization work should be carried out according to the fertilizer characteristics of crops.
Myth 3: As long as the crops grow well, they can get high yields. The growth of crops includes two stages of vegetative growth and reproductive growth (except leafy vegetables and meat stems). In the early stage, nitrogen fertilizer should be used as the main factor to promote vegetative growth. In the middle and late stages, nitrogen, phosphorus and potassium should be combined to promote reproductive growth. . The granular compound fertilizer produced by Sichuan Jifeng uses three layers of coating and graded release to play an important role in crop high productivity.
Myth 4: As long as the fertilizer is applied, it will have a fertilizer effect. Fertilization efficiency is related to soil characteristics, crop varieties, fertilizer nutrient release characteristics, etc. If the effects of various factors are not fully considered, it is easy to cause nutrient loss and even lack of fertilizer. The sandy soil has quick fertilizer effect, but the loss is also fast. The principle of less application and multiple times should be adopted; the clay soil has slow fertilizer effect, and the base fertilizer should be applied and the top dressing should be applied early. Potassium fertilizer is easy to dissolve, but the loss is also fast. The organic fertilizer and phosphate fertilizer have slow effect and less loss. It should be applied early.
Misunderstanding 5: Only pay attention to the amount of fertilization, not to the nutrient content. Nowadays, some compound fertilizers with low or no nutrient content appearing on the market are very popular in rural areas due to their low price. When the farmers applied, the fertilization habit of high-content compound fertilizer was continued. As a result, the nitrogen, phosphorus and potassium applied were insufficient, which caused the occurrence of crop deficiency and deficiency, which affected the yield and quality.
Misunderstanding 6: There are many fertilizations and the benefits are high. According to the principle of diminishing returns, when the fertilization reaches a certain amount, the input-output ratio decreases, and the benefit decreases. If too much fertilization, it will result in reduced production. The high-concentration potassium sulphate (type) compound fertilizer produced by Sichuan Jifeng has scientific research on fertilization, local conditions and the amount of use, and it is not wasteful or more realistic.
Misunderstanding 7: Pay attention to a large number of elements and ignore trace elements. A large number of elements are the basic elements for the growth of crops, but if the trace elements are not added, it will cause plant malformation, falling flowers and fruit, product yield and quality degradation. Therefore, in the process of applying a large number of elements, it is necessary to apply various trace elements such as iron, manganese, zinc and boron to ensure the normal growth of crops according to the fertilizer characteristics of the crops and the composition of soil nutrients.

Crop fertilization, beware of seven major mistakes
In the mountainous areas, farmers have lower levels of farming, and there are many misunderstandings. It is prone to improper fertilization, resulting in poor fertilizer efficiency, slow effect, and even plant death. Therefore, in the process of fertilization, Sichuan Jifeng reminds you to pay attention to the following aspects:
