Citrus planting in Yuxi city is basically distributed in mountain areas, and most of the soil in mountain areas is red (yellow) soil and purple soil, wherein most of the soil has a pH of 5.5-6.5 (acidic to weak acidic), but the soil has a pH of less than 5.0 from strong acid to extremely strong acid, which accounts for about 25%, and the soil having a pH of 7.5-9.0 from alkaline to strong alkaline, which accounts for 11.4%.
The effective state Fe, mn, zn, cu, B of the alkaline earth (pH 7.5-9.0) has lower content of trace elements, and the antagonism of Ca and B, P and elements such as Zn, P and Fe affects the absorption of trace elements by the rock sugar orange plants, so that physiological diseases such as zinc deficiency, iron deficiency, manganese deficiency and the like occur in the plants, and the yield and quality are affected. As fruit growers plant crystal sugar oranges on the soil by adopting a conventional planting technology, leaves at the upper part of plants are easy to lose green and yellow, whiten and cluster leaves, and the plant is seriously expanded to the whole plant, so that the leaves fall off, the fruits are smaller, and physiological fruit fall is serious.
