Effect of potassium dihydrogen phosphate fertilizer
Potassium dihydrogen phosphate plays a more important role in all fertilizers, and the effect is obvious after reasonable use, as follows:
1. Promote growth. Potassium dihydrogen phosphate can play a good regulatory role on plants, such as promoting flower bud differentiation of crops, increasing the number of flowers, strengthening flowers and protecting fruits, preventing fruit and flower drop caused by insufficient plant nutrition, and improving the fruit setting rate. Especially in the fruiting period, it can promote fruit expansion, coloring, sweetening and accelerating maturity.
2. Promote nutrient absorption. In addition to its many effects on plants, potassium dihydrogen phosphate can also promote the full absorption of nitrogen and phosphorus by plants. It seems to have a spirit of helping others, which is rare in many types of fertilizers.
3. To enhance plant stress resistance, you must have mentioned some functions in many processes of plant fertilization, such as improving stress resistance. In fact, this stress resistance means that it can enhance the adaptability of plants to the current growth environment without rising due to unreasonable external conditions. Potassium dihydrogen phosphate also has this function, It can promote the growth ability of plants and enhance the drought, cold and stress resistance of crops, which is like a shot of cardiotonic.
4. To improve photosynthesis, photosynthetic respiration is essential for plant growth. Just like people's exhalation and inhalation, in the case of weak respiration, this person will certainly have problems. This is also the reason for plants. Applying appropriate potassium dihydrogen phosphate fertilizer to plants can enhance the photosynthetic respiration of plants, Then this can promote the absorption, transformation and utilization of nutrients by plants, and enhance the growth of plants.
5. Enhance disease and insect resistance. You must have seen some in some fertilizer effect descriptions, saying that it will enhance the disease and insect resistance of plants. This does not mean that fertilizer itself can protect plants from diseases and insect pests, but from the side, the effect of this fertilizer on enhancing plant growth, for example, like people. If people eat well and absorb well, Then this person's physical health will certainly be better than ordinary people, and his resistance to common diseases will be much better than ordinary people.
Spraying time of potassium dihydrogen phosphate on leaves
1. Before flowering, if you plant flowering plants, it is recommended that you spray a certain amount of potassium dihydrogen phosphate to the plants about a week before flowering, and its ratio can be controlled at 1:1000. For example, if you take a gram of potassium dihydrogen phosphate fertilizer, you need to dissolve it with 1kg of water before spraying on the leaves.
2. As a result, if you are planting fruit bearing plants, you can spray potassium dihydrogen phosphate properly after the plants bear fruit, which can promote the fruit expansion, prevent nutrient deficiency and fruit drop, and spray it properly in the middle and late stage of maturity, which can improve the color, taste and sweetness of the fruit.
