During the growth period of watermelon, the leaves from green to yellow appeared, the area of ​​green leaves decreased, and the photosynthesis decreased, which seriously affected the yield. Only the cause of the yellow leaves is clear and the right medicine can be taken in time to prevent and control. 1, watermelon vines at the top internodes significantly shortened, easy to cross-stem stem and a red-brown gel flow out, become brittle and easy to break, and new leaf growth is slow, uneven surface. Shrinkage, small inward roll, pale yellow leaves, similar to symptoms of viral disease. This is a yellow leaf phenomenon caused by boron deficiency disease. It is caused by soil drought and the absorption of boron by the root system. Watering should be done as soon as possible to keep the ground see dry see wet (that is, early and late humidity, white skin at noon), and spray 400-500 times borax aqueous solution, spray once every 7 days, spray 2-3 times continuously. 2. Leaf margins are yellow, and the leaves roll outwards in an umbrella shape. The leaves turn inwards at noon and are restored in the evening. It is a calcium deficiency disorder. The reason is that there are too many chemical fertilizers and there is less organic fertilizer. Decomposition of chicken manure should be promptly applied to recover 1200-1500 kilograms of chicken manure. Immediately after recovery, sufficient amount of calcium chloride solution should be sprayed and 0.2-0.3% calcium chloride solution should be sprayed. The spray should be sprayed every 10 days and sprayed twice. 3. The leaf margin of watermelon turns from brown to yellow, and in severe cases the brown color expands inwards, which is caused by potassium deficiency. Should apply topdressing 25 kg of potassium sulfate to the roots of watermelons in time per acre, spraying 0.3% potassium dihydrogen phosphate 2-3 times on the leaves, which can quickly restore normal watermelon growth. 4. The yellow veins of the mesenchyme near the main veins of watermelon leaves are gradually expanded to the surroundings, which is the performance of magnesium deficiency. Can spray 0.2% magnesium sulfate 2-3 times, that is to restore growth.
