The root system of Yangmei is shallow, the main root is not obvious, and the fibrous roots are well developed, mainly distributed in the soil layer more than 60 cm. Although Yangmei has root bacteria, it can grow well in relatively thin and well-drained sloping lands, and generally does not need fertilization, but bayberry is very sensitive to the reflection of boron fertilizer. In the boron-depleted soil, the branches and leaves of bayberry will appear water-like half The transparent spots eventually lead to baldness in the leaves, while the meat of the fruit is thick and the flavor is poor. The application of boron fertilizer can effectively prevent the baldness of the branches of bayberry branches, make the meat column of bayberry fruits dull and round, have many juices, be soft and delicious, and have good flavor and improve the yield of individual plants.
Application method of boron fertilizer on bayberry
