In traditional agricultural farming, farmers have the habit of applying various fertilizers with rainfall or irrigation. 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.
The fertilization has the characteristics of simple operation and rapid fertilizer efficiency, so it is generally used as a top dressing in the crop growth period, mainly in the long-term or large-scale fruiting period of some economic crops such as various vegetables and fruit trees. 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 when planting crops in greenhouses in winter, because of the unfavorable conditions such as low temperature and insufficient sunshine, it is effective to select a kind of reliable fertilizer application.
Some farmers' friends think that fertilizing is simply applying fertilizer 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-rooted leafy crops, or crops that are inconvenient for topdressing, they can be applied with water, but the amount of water should be controlled, not too little or too much, and the nutrient distribution should be uniform. For some deep-rooted crops such as cucumber, tomato and fruit trees, ditch application or acupoint application should be carried out. Before application, the fertilization 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.
It is important to note that there are several types of fertilizers that cannot be mixed at will, otherwise the effect is reduced or even no effect. For example, ammonium bicarbonate cannot be mixed with strong acid fertilizer, amino acid fertilizer can not be mixed with humic acid fertilizer, and phosphoric acid fertilizer should be added with zinc, manganese, iron, copper and other fertilizers to add chelating agent.
In addition, the application of fertilizer should be scientifically applied, a small number of times. For example, amaranth can be applied once every time, and cucumber, eggplant, pepper and other solanaceous fruits can be applied once every time. Each time, a large amount of elements, trace elements and plant root growth promoters can be reasonably matched. .
The type of fertilization should be determined according to the soil fertility capacity, the amount of base fertilizer applied, and the fertilizer requirement of the crop. Then, the specific period, application amount and application method of the fertilization should be read in detail. It should be referred to the product description of the selected type. It is not allowed to make a claim based on traditional experience.
