Vegetable planting skills: the five major fertilization errors in vegetables have long been known
Vegetable growers often like to learn some techniques of fertilizing vegetables, but not all fertilization techniques are applicable to their own vegetables, and some vegetables are misunderstood. Have you noticed it? In cold weather, people are cold and cold, and your vegetables will be cold. The difference in temperature will not only affect the absorption of nutrients by crop roots, but also interfere with the opening and closing of leaf pores, thus affecting the absorption of supplementary nutrients by leaves. For example, at low temperatures, roots are poorly absorbed by calcium and magnesium; at high temperatures, nutrient absorption is good and easily caused by length. Sometimes the fertilizer is applied, but the effect is not obvious? We have to understand the utilization of fertilizers, which are actually related to many factors, such as the condition of the crop itself, the characteristics of the fertilizer itself, the process of use, and the environmental conditions of application. If there is a deviation on either side, the problem will arise. Some artificial misunderstandings of fertilization are also a factor that contributes to the problem of fertilization, such as the following. 1. More fertilization, the higher the yield In order to pursue high yields, some farmers will involuntarily apply more fertilizers. However, after the amount of fertilizer is increased to a certain extent, the fertilizer will continue to be added, and the yield will not continue to increase. On the contrary, it may reduce production, increase the disease, lead to deterioration of quality, and increase soil compaction and salinization. Both high yields are achieved through extensive fertilization, but the corresponding unit area gains are not necessarily the highest. Reminder: Vegetable production is affected by many factors such as variety, density, irrigation, etc. Fertilization is only one of the measures to help high yield. 2. Fertilizer has more effect than organic fertilizer In the second half of the use of chemical fertilizers, the obvious reaction can be seen on the crop phase, and the fertilizer efficiency is fast, so many farmers feel that the fertilizer is strong. The fertilizer efficiency of organic fertilizer is slow, and no obvious effect can be seen. In fact, chemical fertilizers and organic fertilizers are two different types of fertilizers, each with its own advantages and disadvantages. The fertilizers have a single nutrient, the effective period is short, and a variety of fertilizers are needed. The organic fertilizer has a long effective period and can improve the quality and fertility. Reminder: Adding organic fertilizer, combined with the rational use of chemical fertilizer, can increase production and improve quality. 3. The higher the fertilizer nutrient, the better. In general, farmers will choose more than 40% of high-concentration fertilizers in a similar manner, blindly rejecting low- and medium-concentration fertilizers. Long-term use of high-concentration fertilizers, neglecting the supplement of medium and trace elements, resulting in calcium, magnesium, silicon, boron, zinc and other trace elements in the vegetable field are in a state of deficit, the phenomenon of deficiency is becoming more serious. Reminder: Reasonable use of high-concentration fertilizer, there are plans to supplement the medium-concentration fertilizer to better balance the supply of various nutrients. 4. think that the fertilizer with good solubility is good fat Each fertilizer has its own characteristics and nutrient release characteristics. A well-dissolved fertilizer has good release properties, but it is easy to lose. It needs to be used in small quantities. If the dosage is too large, or if it is flooded with large water, it will easily cause a large loss of nutrients, and the effect is not as good as others. The controlled release fertilizer can achieve the purpose of safety, long-term efficiency and high efficiency, and is the main direction of modern fertilizer development. Reminder: Use the fertilizer together, don't just see the advantages and see no defects. 5. Superstition import goods Some vegetable farmers blindly worship foreign goods and think that imported fertilizer is a good fertilizer. In fact, China's fertilizer production technology is not much different from foreign countries. A large number of fertilizer efficiency comparisons prove that as long as the product meets the standard and the same nutrient input, the imported diammonium, potassium fertilizer, compound fertilizer and domestic products have the same fertilizer efficiency. Reminder: Keep your eyes open and look at the fertilizer. There are good and bad things at home and abroad.
