Citrus grows faster in the summer, and it is also a critical period for the production and quality of oranges throughout the year. However, due to the high temperatures in the summer, if it happens suddenly, the improper management will affect the annual harvest. Therefore, summer management is particularly necessary. In the following, the key points for the summer management techniques of citrus groves are proposed in combination with the growth characteristics of citrus:
First, reasonable wipe buds. Unsuccessful saplings, until the summer shoots grow to about 5 leaves, timely picking heart, and promote the mature branches. As a result, the summer trees should be wiped out of the summer shoots, and the branches of the fallen fruit trees should be cut short to stimulate the early autumn shoots. At the same time, we must also scientifically determine the proportion of leaf to fruit in each tree of 30:1.
Second, formula fertilization. In the summer, it is the fruit swelling period of citrus fruit. The nutrient supply of the tree body must be sufficient. Generally, the time for applying the strong fruit fertilizer should end at the beginning of July at the latest. Fertilization should be formulated fertilizer, nitrogen, phosphorus, potassium ratio of 10:8:6. In the process of soil fertilization, foliar spray fertilizer is also applied to form an up-and-down omni-directional increase of tree nutrients.
Third, pest control. The main prevention and control of anthrax, red spider, black-spotted whitefly, arrowhead warts, aphids, etc., to ensure that the tree grows robustly.
Fourth, drought relief. If the weather is dry during fruit expansion, the orange orchard must be filled with water in a timely manner. After the heavy rain, the water in the low-lying and low-humidity garden should be promptly removed.
