Cucumber grower Zhao Daniu is a very frugal person. Although he is very good at saving himself, Lao Zhao is a big man in planting cucumber. Every time he uses more fertilizer than others, in his words, he has to feed the ground. It can give you more cucumbers. However, this year there was something that made Zhao Daniu feel overwhelmed. The cucumber was white, like the frost. The leaves of the cucumber seedlings were dark and the roots turned black. The melons were late and the knots were The melon is small and the coloring is not good, and the final yield is not high. In the face of this situation, Lao Zhao is very depressed. I believe that many people and growers like Zhao Zhao have encountered this kind of problem in planting cucumbers. I don’t know how to solve them. Today, Huinong.com has compiled a solution for cucumber planting and frosting. In fact, the phenomenon of cucumber frosting is because the salinization of cucumber is too serious. To change this phenomenon, first find out the cause of salt accumulation, and secondly, take corrective measures. Four reasons for the accumulation of salt in cucumber cultivation 1. Cucumber field has too much fertilization at one time, resulting in difficulty in absorption and precipitation of salt. 2, the proportion of fertilization is biased, partial application of nitrogen fertilizer, especially urea, ammonium bicarbonate, ammonium chloride. 3, long-term application of chemical fertilizers, lack of organic fertilizer. 4, covering the greenhouse, the amount of fertilizer loss should be less, the concentration of salt is relatively high. Take measures to prevent soil salinization in cucumber planting 1. Rim planting. If the soil accumulates salt, plant the eggplant after planting the eggplant. 2. Balanced fertilization in cucumber cultivation, mainly based on fertilized organic fertilizer, supplemented by quick-acting nitrogen fertilizer. 3. Irrigation and drainage of salt. When the land is idle, the salt concentration is reduced by irrigation. At the same time, kill some bacteria. 4, the biological bacteria to dissolve the salt, when the cucumber occurs during the growth of salt damage, the use of biological bacteria can alleviate the salt damage and restore the normal growth of cucumber. The above is the reason and preventive measures for cucumber planting frost, scientifically planting cucumbers, don't think that it is a good thing to feed more fertilizers. Understanding the habits of cucumber can make cucumber planting the biggest benefit. Features
