First, apple potassium deficiency symptoms:
The leaf margins of the basal and middle leaves are chlorotic yellow and often curl upward. When the potassium deficiency is heavy, the chlorotic part of the leaf margin becomes brown and coke. In severe cases, the whole leaf is scorched and hung on the branch, which is not easy to fall off.
Correction method:
Ample organic fertilizer is applied in the autumn. At the beginning of the expansion period of young fruit, 20 to 25 kg of potassium sulfate or 15 to 20 kg of potassium chloride are applied per mu. The foliar spray portion is 0.2%-0.3% potassium dihydrogen phosphate aqueous solution, or 1%-2% potassium sulfate or potassium chloride.
Second, apple potassium excess symptoms:
It is easy to induce magnesium deficiency, which is affected by the absorption and utilization of nitrogen, calcium, iron, zinc and boron. The peel is thick, the hardness is small, and it is easy to be woven, and it is not stored and stored.
Correction method:
Increase irrigation and reduce the concentration of potassium in the soil. Potassium fertilizer should be used sparingly if livestock excrement is used.
Third, skillfully apply potash
The absorption of potassium by apple trees is less in the early stage of growth, and gradually increases later. The critical period of absorption is in the middle and late growth stages, generally from July to August. Applying the right amount of potash to the fruit trees during this time will get twice the result with half the effort. If the same amount of potash is applied before early spring or flowering, there will be no obvious effect on the yield and coloration.
When applying potassium fertilizer, potassium sulfate should be selected with high absorption efficiency and obvious effect, followed by potassium chloride, or organic fertilizer with high potassium content such as grass ash or decomposed chicken manure can be applied under the tree, and then Shallow watering. If the leaf surface spray is supplemented with 0.3% to 0.5% potassium dihydrogen phosphate solution or amino acid potassium 300-500 times solution, good results can also be obtained.
The clever design sports high peel strength and substrate rigidity, paired with low shrinkage and excellent creep consistency, resulting in reliable repeatability and minimal hysteresis. A special cover layer enhances sealing, safeguarding the sensor's performance and making it well-suited for sensitive applications requiring stability, such as C3 level precision tasks.
Calibration is a breeze, as heat treatment allows fine-tuning of the temperature characteristic sensitivity coefficient. This adaptability makes our material perfect for non-external compensation sensors operating with a tight tolerance range of 0.03% to 0.05%.
By streamlining these two versatile materials' properties, we've developed a product that doesn't just meet but exceeds the demanding requirements for precision sensor systems. Choose our laminate for an uncompromised, stable, and protected sensing experience.
Apply potassium fertilizer to improve apple quality
Potassium is one of the important elements needed for fruit trees, especially for improving apple quality and improving fruit quality. Therefore, potassium fertilizer is also called fruit fertilizer. Applying potassium fertilizer at an appropriate amount in a timely manner can significantly increase the fruit, increase the sugar content, and increase the degree of coloration. It also makes the fruit color bright, the peel is smooth, and the inner quality of the flavor is improved. The resistance to pests and diseases is also improved, and the storage and transport resistance is enhanced. The application rate is preferably 1 kg of pure potassium per 100 kg of yield. If the application is excessive, the physiological function of the fruit tree will be destroyed, which will affect the absorption and utilization of other elements.
