How to apply correct fertilization

In the traditional agricultural farming process in China, farmers have the habit of applying various fertilizers to supplement crops with natural rainfall or irrigation with water. However, because the amount of watering is uncertain, the nutrient content of the fertilizer used is low, the composition is single, and the water solubility is poor, which makes the effect of flushing fertilization not ideal. If the local nutrient concentration is high, the seedlings are burnt, and the concentration of nutrients far from the water source is too low and there is no fertilizer effect. Although there are some drawbacks to the application of fertilizer, it also has its own many advantages. For example, the raw materials suitable for flushing are generally water-soluble, the nutrients are not easily solidified by the soil, the soil is not compacted, the plants are easily absorbed, and the fertilizer effect is fast, and no Toxic residue. In addition, today's flush fertilizer is generally a compound fertilizer containing a variety of nutrients, which is in line with the future development direction of fertilizer and the demand for modern agricultural intensification. Therefore, in recent years, fertilizer manufacturers all over the country have developed the fertilizer as a separate fertilizer variety, and have carried out large-scale promotion and application, and achieved good economic and social benefits.

The following is a brief introduction to the types and applications of flushing fertilizers on the market, so that farmers have a preliminary understanding and correct purchase.

First of all, there are two types of physical fertilizers: liquid drums and solid powder bags. From the chemical properties of fertilizers and the internal nutrients, it is mainly divided into three types: one is organic type, such as amino acid type, humic acid marine biological type, etc.; the other is inorganic type, such as potassium dihydrogen phosphate type, high calcium high. Potassium type; one type is microbial type, such as photo-bacteria type, enzyme type. In addition, there is a new type of flushing fertilizer produced by scientifically processing and compounding raw materials such as organic, inorganic and biological materials. It is a compound preparation, and the “Jingnong” series produced by Beijing Oasis Star Technology Co., Ltd. This is the case with fertilization. The nutrient requirements for different crops can be divided into broad-spectrum, vegetable-specific, fruit-tree-specific and special economic crop-specific types.

The fertilization has the characteristics of simple use and rapid fertilizer efficiency, so it is generally applied as a top dressing variety in the crop growth period in practical application. Mainly in some economic crops such as various vegetables, fruit trees, etc., when long-term or large-scale results require nutrients for a long time. At this time, if ordinary fertilizer is applied, the release of nutrients is slow and the fertilizer efficiency is slow, which will inevitably affect the yield and quality. Especially in the greenhouse cultivation of crops in winter, because of the unfavorable conditions such as low temperature and insufficient sunshine, it is very good to choose a reliable quality fertilization application.

So how to apply fertilization? Some farmer friends feel that the application of fertilizer is washed with water! In fact, this is a wrong understanding. The principle of applying fertilization and applying other fertilizers is the same, as well as deep application and concentrated application. For some shallow root leafy vegetables or cropping inconvenient crops can be applied with water, but to control the amount of water, not too little or too much to promote the distribution of nutrients evenly. However, for some deep-rooted crops such as cucumber, tomato and fruit trees, ditch application or acupoint application should be carried out. Before application, the fertilizer can be diluted to a certain multiple, evenly distributed to the previously dug trench or hole, and then a small amount of water can be poured. .

What are the precautions in the application process? Firstly, according to the soil fertility capacity, the amount of base fertilizer applied and the characteristics of the fertilizers to be planted in the planting area, the suitable varieties of fertilization should be determined. Then read the instructions for the purchase of the applied fertilizers in detail, and master the appropriate fertilization period, application amount and application method. It is not possible to make a claim based on the previous experience of fertilization alone, so as to avoid unnecessary losses.
