Mulberry leaf spray fertilizer production increase
Mulberry leaf spray fertilizer can improve the yield and quality of mulberry leaves. It is a kind of mulberry assisted fertilization method, and it is also one of the measures for rapid and high yield in mulberry field. If applied properly, it can increase production of more than 10% of mulberry leaves. Mulberry leaf surface fertilization has the following characteristics: First, fast absorption, fast transportation, and quick results. The second is that nutrients are used directly to avoid the fixation of the soil, which results in high fertilizer utilization. The third is that the fertilizer effect is short, and the general fertilizer effect period is a few days or more than ten days. Then, under what conditions will the mulberry be fertilized? First, when fertilizer is low, foliar fertilization may be applied to prevent the soil from becoming fixed. Second, when the drought, rain, blisters and wind and frost disasters were encountered, the root absorption function decreased, and the use of foliar fertilization could receive good results. Third, the summer felling caused the roots of the mulberry to fall off, and the absorption was suspended. When the aboveground growth was lack of mineral nutrition. At this time, fertilization is applied to the leaves of the remaining leaves and young leaves, and the effect is good. Fourth, the high-yielding mulberry gardens grow during vigorous periods, and the mineral nutrients absorbed by the roots are often in short supply. At this time, foliar fertilizer is applied to supplement the nutrients, and the effect is also very good. Foliar fertilization should pay attention to the following points: 1, spraying time, the best evening, followed by morning dew when the early dry. 2. At the spraying site, the absorption rate at the back of the leaf was 4 times higher than that at the front, and the absorption rate at the young leaf was 60% higher than that at the old leaf. Therefore, the foliar fertilizer should be sprayed on the back of the young leaves on the upper part of the mulberry branches. 3, foliar fertilization to dilute is appropriate, the concentration should not be too high. 4, frequency and dosage, every 5-7 days 1, even spray 2-3 times, each time about 667 square meters with a liquid volume of about 100 kg. 5. Sprayer must be washed before applying foliar fertilizer to avoid contamination of mulberry leaves with pesticides. If it rains within 6 hours after spraying, re-injection is required.
