Due to the influence of climate this year, the orange trees bloomed earlier, and the field management after the orange trees flowered mainly carried out the following work:
Reasonable fertilization Deeply apply stable manure or cake fertilizer, bran fertilizer, etc. after the orange tree has flowered, which can promote fruit swelling, and at the same time it has obvious effects on solving the lack of trace elements, sweetening and acid reducing, enhancing fruit smoothness and fruit color. . Generally, 3 kg of cake fertilizer should be applied to each plant, and 50-100 kg of rotten farm manure. Orchards with coarse-skinned large fruits, light-colored or late-maturing plants should not apply nitrogen fertilizers, or those with thick acid skin should use less potassium fertilizers.
According to the rain and the orange orchard soil compaction, shallow loose soil shall be subjected to shallow plowing to keep the garden soil loose and breathable. At the same time, pick up the soil from the tree pocket, level the garden soil, and grow soybeans or mung beans.
Note that spring shoots (new shoots harvested from March to April) and summer shoots (new shoots harvested from May to June) that cause excessive fruit growth often cause falling flowers and fruits. Spring and summer shoots should be more controlled and less promoted. In addition, the fruit protection medicine should be sprayed after the flowers are flowered and before the second physiological fruit drop; ditch drainage in the rainy season to improve the resistance of the tree vigor; prevent anthracnose, brown spot and other diseases.
