Organic fertilizers not only provide a variety of nutrients for vegetables, but also the gradual decomposition of organic fertilizers, which is conducive to improving the quality of vegetables and improving quality. Mainly cabbage, green vegetables, spinach, leeks and so on. Nitrogen fertilizers are the main nitrogen fertilizers for leafy vegetables, but phosphorus fertilizers and potassium fertilizers must also be added at the same time as the application of nitrogen fertilizers. Such as the cultivation of cabbage, into the rosette period and 2 times before the package of fertilization, is the key to high yield. If the supply of such vegetables in the whole growth period is insufficient, the plants are dwarf and the tissues are rough. The spring-grown leaf vegetables are also easy to twitch early. The late phospho-potassium fertilizers of the cabbage-leaf vegetables are often not easy to shoot.
Including melons, solanaceous fruits and legumes, edible parts of which are all reproductive organs. Generally, seedlings need more nitrogen, but too much nitrogen fertilizer can easily cause leggy, but it will delay flowering, result in increased flowering and falling fruit; During the growing period, the demand for phosphorus increased sharply, and the amount of nitrogen required decreased slightly. In this period, phosphorus and potassium fertilizers should be increased to control the amount of nitrogen fertilizer. After cucumbers were set up, they should be re-fertilized. After each batch of melons, the fertilizer and water should be added.
There are radish, carrots, simmering, etc. The edible part is fleshy roots. The main growth stage is to supply nitrogen fertilizer, which promotes the formation of large green leaves. During the middle and late growth stage (the fleshy root growth stage), more potassium fertilizer is needed to control the amount of nitrogen fertilizer. To promote the assimilation of leaf transport to the roots, in order to form a strong fleshy roots, if the late nitrogen fertilizer is too much and potassium is insufficient, it is easy to make part of the ground long, small roots, yield, quality deterioration.
In large and medium sheds, the cultivation of vegetables in greenhouses is much larger than the amount of fertilizer applied per unit area of ​​open soil, and most of the remaining fertilizer remains in the soil due to no rainwater leaching, which results in excessive concentration of soil solution and hinders root absorption of nutrients or damage. Root system. Therefore, the cultivation of vegetables in facilities should fully consider the aftereffects of the former fertilizer, apply more organic fertilizer, appropriately apply less fertilizer, and measure the soil nutrients using the soil nutrient tester to avoid the damage caused by salt accumulation and further protect the crops. The advantages of vegetables.
Here are some types of OE replacement exterior car door handles: pull up, pull out, and trigger.

Application of Soil Nutrition Differentiation Tester in Vegetable Planting
Vegetables are people's constant food on the table, their variety is also numerous, and their biological characteristics are not the same. The nutrients they need during planting are also very different. Therefore, it is unavoidable to adopt different fertilization methods. The roots of all kinds of vegetables during the seedling stage are still underdeveloped, and the amount of nutrients absorbed is not too large, but the requirements are very high. Some thin and quick-acting fertilizers should be properly applied. During the vegetative growth period and the result period, a large amount of nutrients must be absorbed, and sufficient fertilizer must be supplied, usually in stages. Top dressing, alternation of organic and inorganic fertilizers, complete combination of NPK fertilizer and trace fertilizer, and combination of fertilization and irrigation, etc., in order to give full play to the role of fertilizers in increasing production. During the planting process, the soil nutrient tester was used to measure the soil nutrients, and corresponding fertilization measures were taken.
