In the process of crop growth, multiple application of fertilizer is required. In addition to the application of base fertilizer, people also carry out irrigation, root irrigation and foliar application to supplement crop nutrition to achieve high yield. Because the crops mainly rely on the roots to absorb nutrients, so we can understand the basic fertilizer, the fertilization, and the root fertilizer. Why do we need to apply foliar spray? And how do you choose the foliar fertilizer now? How to use it to achieve the best results? ? First, let's look at the reasons for spraying foliar fertilizer: 1. Insufficient supplementation of root fertilization When the crop is inconvenient for root fertilization, such as the late stage of crop growth, the root activity declines and the ability to absorb fertilizer decreases; or when the soil environment is unfavorable for crop growth, the root absorption of the crop is hindered, and the crop needs to resume growth quickly, if root When the application method can not meet the crop needs in time, only foliar application can be used to quickly supplement the nutrients and meet the needs of crop growth and development. 2, quickly add nutrition In the process of crop growth, crops have shown some nutrient deficiencies, because the use of soil fertilization requires a certain amount of nutrients to be absorbed by the crops, and can not alleviate the symptoms of crop deficiency in time. At this time, using foliar fertilization, nutrients can quickly enter the plant through the leaves, solving the problem of deficiency. 3, give full play to fertilizer efficiency Some fertilizers such as phosphorus, iron, manganese, copper, zinc fertilizer, etc., if applied as roots, are easily fixed by the soil, affecting the application effect, and foliar application is not limited by soil conditions. For example, some fruit trees and other deep root crops absorb less nutrients. If traditional fertilization methods are difficult to apply to the root absorption site, they can not fully exert their fertilizer efficiency, while foliar spray can achieve better results. effect. 4. Reduce soil pollution The application of nitrogen fertilizer to the soil is likely to cause the accumulation of nitrate in groundwater and vegetables, which is harmful to human health. About 75% of the nitrates absorbed by humans come from vegetables. If foliar fertilization is adopted, appropriately reducing the amount of soil fertilization can reduce the nitrate content in plants and residual mineral nitrogen in the soil. In salinized soil, soil fertilization may increase the concentration of soil solution and increase the salinization of the soil. The use of foliar fertilization measures not only saves the amount of fertilization, but also reduces the pollution of soil and water sources. It is an effective fertilization technique with two advantages. 5, economical and cost-effective Various trace elements are essential nutrients in the process of crop growth and development, but the application amount is very small, such as molybdenum fertilizer, the application amount per acre is only a few tens of grams, and it is not easy to apply evenly according to the root application method. Only by foliar application can it be cost effective. How to apply fertilizer to achieve the best results: 1. The period of foliar fertilization should be based on the demand for nutrients in different growth stages of various crops, and the selection of crop nutrient elements should be carried out at the most and most urgently to achieve the best results. 2. Select the appropriate spray time. The effect of foliar fertilization is directly related to temperature, humidity, wind, etc. It is best to choose foliar spray without wind or cloudy or with high humidity and small evaporation before 9:00 am. After 4 pm, if it rains 3 to 4 hours after spraying, it needs to be refilled. I believe that everyone has long looked at the foliar fertilizer varieties on the market. Today, we introduce a new type of pure natural high-concentration essence--the intelligent regulation of nutrient flow to foliar fertilizer, which is the k-dimensional transporter. At present, it is still rare in China. It can break the limit of increasing production: k multi-dimensional transport protein according to the principle of life atomic fission bursting huge energy, energy source continuously supplements energy for crops, 360° all-round to meet all the needs of crops for nutrition and health, no hormones, anti-premature aging, stimulate The high yield potential of crops; the addition of a new generation of intelligent control technology enables the fruit to rapidly expand without resistance. When it reaches a certain level, excess nutrients are automatically transferred to other tissues, which can increase crop yield by more than 30%. It enhances immune bactericidal power: This product quickly inhibits and blocks the formation and germination of pathogenic spores from the source, rapidly proliferates beneficial strains, forms a protective net, and enables plants to actively resist various difficult diseases caused by viruses, bacteria, fungi, etc. Cancerous dysfunction, the maximum amount of pesticides can be reduced by 50%; special preventive and re-repairing effects on repeated morbidity, unknown etiology, complications, complications, and dying of life caused by harsh living environment; Strong vitality, enhance disease prevention and resilience. The main thing is that it will not affect any organisms such as silkworms, fish and shrimps, and bees. I hope everyone can use the foliar fertilizer and choose the right foliar fertilizer.
