In the grape growing season, potassium fertilizer is mainly used for spraying fertilizers outside the roots because it has many advantages such as rapid absorption, good fertilizer effect, and timely supply. The combination of potassium spraying outside the root and preventing and controlling pests together can save labor. Its main technologies are:
Select the type of potash fertilizer. Practice has proved that the application of potash fertilizer outside the roots of grape should be selected potassium dihydrogen phosphate, potassium sulfate, high-quality plant ash leaching liquid and other available potash, potassium chloride should not be used, because chlorine from the permeability, a large number of plants can cause poisoning, and Reduce the sugar content of the fruit and reduce the fruit quality.
Determine the application time. The potassium spray outside the roots of the grapes is mainly carried out during berry enlargement and berry ripening. Plants growing vigorously can also be sprayed when the young fruit after flowering begins to grow. While spraying potassium fertilizer, it is necessary to use nitrogen and phosphorus materials in order to ensure that potassium fertilizer can normally exert its fertilizer efficiency.
Apply the spray concentration. Potassium dihydrogen phosphate is preferably O, 5%-O.8% and potassium sulfate is 0.8%-1. O% is better, and the leaching solution of the ash is suitable for 3%-5%, and the concentration should not be too large to avoid fertilizer damage.
Select spray time. Potassium fertilizer applied outside the root should be carried out before 9 o'clock in the morning or in sunny days and after 5 o'clock in the afternoon. It should not be sprayed in high temperature at noon.
Add adhesive. In the fertilizer solution, add a suitable amount of neutral detergent, etc. as an adhesive to maximize the time for the fertilizer solution to stay on the foliage to ensure that the leaves are fully absorbed and improve the fertilizer efficiency.
Pay attention to spraying techniques. Spray K fertilizer outside the roots of the grapes, spraying both sides of the blade should be evenly sprayed, 60 kg per acre spray fertilizer is better.
Other potassium application routes. After the grapes are harvested, appropriate potassium fertilizer is applied in combination with the autumn basal fertilizer, which accounts for 30%-35% of the total amount of potash fertilizer applied throughout the year.
1000Hz High Frequency LiDAR System
JRT High Frequency Range LiDAR Sensor is 2021 new product, that's a low-cost tof sensor but High frequency (up to 1000Hz). With 5cm high accuracy, the LiDAR Module can measure 80m.
