Melon, fruits and vegetables are essential foods for the daily life of the people. Melon, fruits and vegetables are rich in chlorophyll, lutein, vitamins, trace elements, etc. The essential nutritional elements of the human body, more fruits and vegetables, healthy people, less people, less If you are sick, you must make the fruits and vegetables grow well, high yield, and good quality. You must have sufficient nutritional supply to make the fruits and vegetables grow well, have high yield, and good quality. In order to improve the output and quality, in addition to the soil application Base fertilizer and topdressing should also be fertilized by leaf surface.
This leaf surface fertilizer has less dosage, easy to operate provinces and efforts, high utilization, etc., and can be quickly absorbed by the crops and quickly absorb quickly. Use, improve drought resistance, cold resistance and resistance, and greatly increase production. It can be added in time in the period of fertilizer and sensitivity of crops. Period, spraying potassium nitrate and potassium dihydrogen phosphate can promote the rapid expansion of the fruit. The leaf fertilizer spraying effect is closely related to the spraying area, the site and concentration of spraying, and the spraying time is closely related. , spray crop type. The watermelon, cucumber, tomato, apple, grapes, radishes, cabbage, etc., etc., large leaf area, thin stratum corneum, nutrients in the solution are easily absorbed, and the effect is better. , the fertilization site. The main spray is suitable for the young leaf and functional blades that are suitable for metabolism. Generally speaking, there are more stormhole on the back of the leaf than the front, and the solution is easily absorbed. Drip water is better. three, fertilizer concentration. The spray concentration of different fertilizers has a large difference in spraying concentration. Urea is 0.5%to 1%, calcium phosphate is 1%to 1.5%, potassium dihydrogen phosphate is 0.2%to 0.5%, potassium sulfate is about 0.5%, trace element elements Fertilizer is usually 0.1%to 0.5%. four, fertilization time. The absorption of nutrients in the leaves determines the solution. When the leaves stay, the temperature at noon is high, and the water in the solution is easy to evaporate. Multi -loss is not suitable for spraying. The best time is to be after four o'clock in the afternoon. Is must grasp the concentration strictly when spraying leaf surface fertilizer, and try to use a small amount of multiple principles to avoid fertilizer damage.
There are pores on the leaf surface, which is easier to absorb more nutrients, enhance the activity of enzymes in the leaves. The leaves are more thick and easier to promote the flowering and results of plants.
Sprinkling leaf surface fertilizer has the advantages of small dosage, easy to operate labor and labor, and high utilization and high utilization rate. It can be directly absorbed and utilized by crops, improved drought resistance, cold resistance and resistance. During the period of fertilizer sensitivity, timely supplements, such as carphenia and vegetable flowering period, boron spraying boron spraying can effectively increase the fruit rate. During the expansion of the fruit, spraying potassium nitrate and potassium dihydrogen phosphate can promote the rapid expansion of the fruit.
The fertilizer absorbed by the blade through the pores eliminates the process of root conduction, and directly supplements the demand for nutrients for vegetables. The rapid leaf surface spraying to make up for the lack of lack of washing and absorption capacity. Different vegetables have special needs for certain elements. The effect is relatively obvious. The leaf surface fertilizer is convenient and can be mixed with insectic drugs.
Supplement the insufficient fertilizer, quickly supplement nutrition, give full play to fertilizer efficiency, economically cost -effective, reduce the pollution of the soil, absorb fast, strong effects, save dosage, fertilize on the leaves, can quickly supplement nutrition, increase grain output.
