Now that the weather is warming up, it is the season when farmers are ploughing. At this time, it is a crucial period for crop fertilization. Many farmers feel that there are more fertilizations, and the more crops they produce, the better they are. In fact, there are still many misunderstandings like this. The following small series will introduce some common misunderstandings of spring tillage and fertilization. 1, can not apply unfermented manure After the spring, many crops have already been planted in the greenhouse cultivation process, and the base fertilizer must be applied before planting. Manure is a kind of base fertilizer that most farmers will choose. However, it must be noted that it is not possible to apply unfertilized manure because it causes rooting and the like, and during the decomposition process, the ammonia produced will also cause certain damage to the seedlings of the crop. Especially for tomato plants, the application of unfertilized manure will lead to the outbreak of viral diseases, resulting in severe reductions in production, so it must be avoided in time. 2, can not be applied for long-term ammonium sulfate Ammonium sulfate sold in the market is a physiologically acidic fertilizer which, if applied on the same soil for a long period of time, increases the acidity of the soil. Even long-term application on alkaline soils can lead to hardening of the soil compaction. In summary, the long-term application of ammonium sulfate on any soil has a bad effect, so it is not possible to directly apply ammonium sulfate for a long time. 3, can not apply too much high concentration fertilizer Many farmers' crops are not growing well, and they will find reasons in the fertilizers. They think that as long as the amount of fertilizer is increased, it will definitely produce good results and will help to promote crop growth. But I don't know, it is actually a misunderstanding. No matter which kind of fertilizer, the one-time dose is too large, it will directly damage the roots of the crop, and then affect the growth, the yield will not increase, but will decrease, so avoid blindly Fertilization. 4, can not only use micro-fertilizer Although zinc, boron, rare earth and other micro-fertilizers have a good effect on the "deficiency syndrome" of crops, if the same, if only micro-fertilizer is applied, "micro-fertilizer is the master", it will cause crop malnutrition, growth and development. Limited. Therefore, in fact, it is not possible to see only a little effect of micro-fertilizer, and blindly apply only micro-fertilizer. 5, can not be applied or applied phosphorus fertilizer Because the movement of phosphorus fertilizer in the soil is very small, if it is applied or applied, it will be easily adsorbed and fixed by the soil, which greatly reduces the fertilizer efficiency of the phosphorus fertilizer. Therefore, when applying phosphorus fertilizer to the crop, Do not give or apply. 6, can not be applied to diammonium phosphate as a base fertilizer The use of diammonium phosphate as a base fertilizer or seed fertilizer is more common in the northern regions. But in fact, diammonium phosphate is a kind of high-phosphorus, low-nitrogen, and potassium-free binary compound fertilizer. When applied, it is better to use proper amount of nitrogen fertilizer and potassium fertilizer. 7. After the urea is applied, it cannot be watered immediately. Because urea is converted to amide after it is applied to the soil, if it is immediately watered after application, it will easily be directly lost with water. Therefore, it is recommended to use the method of covering the soil after the application of urea, which is better, and can also improve the fertilizer efficiency. The above are the seven misunderstandings of spring tillage and fertilization. It is a good time for crops to require fertilizer and fertilizer in the spring season. However, farmers should pay attention to avoiding these misunderstandings of fertilization during the peak season of spring farming, so that crops can be better. nutrient.
