As the external temperature gradually decreases, the overwintering vegetables in the greenhouse continue to enter a period of vigorous growth, and the topdressing work of the fertilization has begun. Under the requirement of ensuring moderate yield, how should the fertilization be used? The following is a brief introduction to the types and applications of flushing fertilizers on the market.
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: the first one is organic type, such as amino acid type, humic acid marine biological type, etc. The second type is inorganic type, such as potassium dihydrogen phosphate type, high. Calcium and high potassium type; the third type is microbial type, such as photosynthetic bacteria type, enzyme type and the like. In addition, there is a new type of flushing fertilizer produced by scientifically processing and compounding organic, inorganic, biological and Other raw materials in the market, which is a composite preparation. 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 topdressing variety in the crop growth period in practical application. Mainly in the application of some economic crops such as various vegetables, fruit trees, etc. in the long-term or large-scale results period. 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, it is necessary to select a kind of flushing fertilizer to improve ground temperature, promote rooting and improve fruit quality because of adverse conditions such as low temperature and insufficient sunshine.
So how to apply fertilization? Some farmer friends feel that rushing with fertilizer is rushing with water! In fact, this is a wrong understanding.
The principle of applying fertilizer and applying other fertilizers is the same, as well as deep application and concentrated application. For winter and spring greenhouse vegetable topdressing can be applied with water, but to control the amount of water, not too little or excessive, in order to promote the distribution of nutrients evenly. However, for some deep-rooted vegetables to be ditch or acupoint application, the application of the fertilizer can be diluted to a certain multiple before application, evenly distributed to the previously dug trench or hole, and then a small amount of water can be poured, especially suitable for open-air cultivation.
In the process of using fertilization, according to the soil fertility capacity in the planting area, the amount of base fertilizer applied and the fertilizer characteristics of the planting crops, the appropriate varieties of fertilization should be determined. Then read the instructions for use of the purchased fertilizers in detail, and master the appropriate fertilization period, application rate and application method. You should not make your own claims based on past fertilization experience, so as to avoid unnecessary losses.
