Answer: This is caused by boron deficiency. Correction methods: strengthen management, enhance tree vigor. Strengthen soil management (such as deep plowing), plant green manure, increase the application of organic fertilizer to raise soil organic matter content, improve soil conditions, and increase the soil's boron supply capacity, so as to improve the soil ecosystem and enhance the absorption function of fruit tree roots. During abnormal drought, due to insufficient water, boron deficiency symptoms often appear, so measures such as strengthening irrigation and laying plastic film should be taken to prevent insufficient water supply to the tree.
At the same time, borax solution can also be applied to the soil at the roots, and the best time is 3 weeks before the fruit trees bloom. Boron has high mobility in soil, so it should be applied shallowly and can be mixed with nitrogen fertilizer and phosphorus fertilizer. After leaf fall in winter, broadcast borax over the entire orchard floor. When broadcasting, pay attention to doing it carefully and evenly, 250-400 grams per mu. After applying borax, the entire orchard should be plowed immediately, to a depth of about 10-15 cm.
