Many vegetable farmers have reported that it is difficult to master the winter fertilizer, and if they are not careful, they will suffer from fat damage, resulting in root injury and smoked leaves. Some vegetable farmers planted tomatoes in five greenhouses. After the last fertilizer, they just touched the cloudy sky and could not open the shed. As a result, the tomatoes in the shed were all angered after the shed was opened the next day. To avoid such problems, the "Yunhe Brand" high-concentration potassium sulfate-type compound fertilizer manufacturer - Sichuan Yufeng Industrial Co., Ltd. market department carefully guides you.
For fertilizers, it is necessary to use fertilizers with a graded volatilization or volatility. For example, the “Yunhe Brand†uniform formula is soluble, water-soluble (irrigation) and fertilization, and the nutrients are most suitable at 15-15-15. After the temperature drops, the ventilation of the greenhouse is relatively small, and it is easy to collect harmful gases and cause gas damage. Therefore, it is not advisable to choose a volatile fertilizer. 45% nutrient fertilization, nutrient stability, three-layer envelope, graded release, the effect is particularly good.
The concentration of the fertilizer solution should be appropriate. When watering, the amount of water is generally large, and the fertilizer is highly diluted. If the concentration of the fertilizer solution is too low, the fertilizer efficiency is poor; if the concentration of the fertilizer solution is too high, rooting and rooting are prone to occur. For volatile fertilizers, when the concentration of the fertilizer solution is too high, the amount of harmful gases volatilized into the air is relatively increased, and harmful gas poisoning is more likely to occur.
When pouring small water in winter, the amount of fertilizer applied can be fertilized by about 4/5 of the amount of conventional ground application. The amount of fertilizer applied to the liquid fertilizer is mixed with water, and the water is slightly turbid.
In winter, it is necessary to reduce the amount of fertilizer residues on the ground. When we went to the countryside, we often saw some fertilizers that were not dissolved on the ground. It is recommended to use some water-soluble fertilizers in the low temperature period, such as the “Yunhe Brand†water-soluble rushing (irrigation) fertilization produced by Sichuan Jifeng. When applying organic fertilizer, it must be prepared by using a decomposing agent, and the water-insoluble fertilizer residue is removed and applied.
The amount of water to be poured should be appropriate. Winter fertilization should not be flooded with large water to reduce the loss of nutrients in the fertilizer with water. However, it is not possible to water too little, to prevent the fertilizer concentration from being too high, and to cause surface salinization after long-term high-concentration fertilization. The suitable amount of watering is: after watering, the water can wet the soil in the main distribution area of ​​the root system. After watering, the wooden stick can be inserted into the soil to check the wetness of the soil layer to determine whether the watering amount is appropriate.
