Fertilizer is an important means of production in agricultural production. Fertilization plays an extremely important role in the increase of production in modern agriculture. People's daily life in the "fertilizer is the food of the crop," "a crop of flowers, relying on the fertilizer headed" and other farms also fully affirmed the importance of fertilization, especially rational fertilization.

Usually, we divide the fertiliser into three categories: base fertilizer, seed fertilizer, and top dressing. The supply, demand and consumption of the elements necessary for plant growth need to be kept in balance. In this regard, Beijing Huaxia Kangyuan Science and Technology Co., Ltd., together with agricultural experts such as the Chinese Academy of Agricultural Sciences and the Chinese Academy of Sciences, gives the following characteristics of each fertilizer according to different stages: Suggest:
1. Base fertilizer application points Base fertilizer is fertilizer applied before sowing or planting, also called base fertilizer. The purpose of its application is to improve the soil and provide nutrition for the later growth of the crop. The specific amount of base fertilizer can be determined by referring to the comprehensive factors such as local planting results and target yield for many years. Generally, only 30% of the total amount of nitrogen fertilizer is used as the base for high fertility soil, and 50% to 70% of nitrogen fertilizer is required for medium and low fertility soils. Base fertilizer, while phosphorus, potash and trace fertilizer are all applied at the same time as much as possible. Basal fertilizer is generally dominated by organic fertilizer. It can mix 1-2 kg of golden treasure microbial fertilizer per acre (click here for details) and apply improved soil structure. The golden treasure microbial microbial fertilizer can effectively break the soil compaction and solve the problem of double dead trees. The compound bacteria content is as high as 4-7 billion grams, which significantly improves the ability of the plant to resist root rot and blight, and improves the fertilizer utilization rate. Moreover, beneficial organisms continue to secrete cytokinins, indole acetic acid, and gibberellins during reproduction and metabolism. The active substances that are beneficial to the growth of crops, such as prime, promote rooting and increase the number of hairy roots; increase water and fertilizer absorption capacity; strong stems and thick seedlings; no slow seedlings for transplanting; greatly improve crop quality and yield. Microbial fertilizer nutrition contains a large number of trace elements such as calcium, boron, iron, zinc, magnesium, etc., which can effectively supplement the various nutrients needed by the crop during the whole growth period and truly balance nutrition of the crop. When the basal fertilizer is applied, it is generally combined with deep ploughing, stripping, and culling.
2. Seed Fertilization Fertilization Point Seed Fertilizer is a fertilizer that is mixed with the seed when it is sowed or cultivated. Seed dressing and fertilization can be done through seed dressing, soaking, sticking, axillary or rooting. Fertilizers commonly used as seed fertilizers include decomposed organic fertilizers, humic acids, amino acid solids, liquid fertilizers, microbial fertilizers, and quick-acting fertilizers. Fertilizer application may increase the concentration of available nutrients around the roots and promote root development; or it may compensate for the lack of seed endosperm storage and improve seedling traits. Fertilizers and basal fertilizers can be applied in combination with layered fertilization so that the crops can be used in layers to obtain nutrients.
3. Top dressing fertilizer points Top dressing is a nutrient fertilizer that is applied to regulate plant nutrition and supplement some nutrients in the soil during crop growth. The characteristics of top-dressing application are relatively flexible, and are mainly implemented according to the different symptoms exhibited in different stages of crop growth. There are many kinds of topdressing, most of which are called according to different development stages of the crop, such as nursery fertilizer, jointing fertilizer, panicle fertilizer, and grain fertilizer.
The first thing to consider when topdressing is symptomatic fertilization, that is, “what is lacking?†Secondly, it is necessary to reasonably select the type of topdressing, such as ammonium bicarbonate, ammonium phosphate, and phosphate rock in phosphate fertilizers, which are ineffective or harmful to foliar spraying. Spraying is prohibited. Urea, potassium sulfate, potassium dihydrogen phosphate, boric acid, zinc sulfate, agricultural aspirin, etc. can be sprayed directly in the form of foliar fertilizers; in addition, chemical fertilizers such as superphosphate and gold baby series Mixed application of biological bacterial fertilizer is also a method of top-dressing approved by farmers in recent years. The amino acid chelated calcium, black humic acid and other substances contained in the bacterial fertilizer can not only improve the quality of the fruit, but also reduce the proportion of fruit and fruit, and It can effectively fix fertilizer nutrients and prevent soil compaction. Finally, when top dressing, it is necessary to adjust the top dressing concentration and time according to different plant characteristics.
