First, select excellent varieties:

There are many kinds and varieties of citrus that can be planted in our country, so we must choose excellent varieties according to the local ecological conditions and market demand. Variety selection, with the market demand and scientific and technological progress, more and more varieties. When selecting varieties, we should first understand that there are differences in the adaptability of different varieties to adverse weather. It is best to choose some varieties that can resist canker; secondly, choose the varieties with good comprehensive economic characters and suitable for local cultivation conditions promoted in the current market.

Second, the ecological conditions are suitable:

Citrus belongs to small evergreen trees or shrubs under tall trees in tropical rain forests or subtropical evergreen broad-leaved forests. The suitable temperature in the area above 15 degrees requires soil rich in organic matter and water, and a partially shaded environment, which also forms the characteristics of citrus evergreen, shade tolerance, low temperature tolerance, water preference in roots and rich soil organic matter.

Third, adopt formula fertilization:

The absorption of nutrients by citrus is different in different seasons and phenological periods. Sprouting in spring absorbed less nitrogen, phosphorus, potassium, calcium and magnesium, and increased with the elongation of new shoots, and the flowering stage increased the fastest. Therefore, in the planting process, combined with the needs of various growth and development stages of citrus trees, according to the proportion of various fertilizers needed, and according to the percentage of fertilizer that can be absorbed and utilized in the soil, to determine the amount of fertilizer a scientific fertilization method. Adopting the technology of soil testing and formula fertilization can achieve the goals of saving fertilizer, increasing yield and improving quality, high efficiency of fertilizer allocation, soil improvement and ecological protection.

Fourth, irrigation and drainage:

Citrus is evergreen all the year round, the annual growth of branches is large, the fruit hanging period is long, and the demand for water is high. According to the investigation, the annual water consumption of Wenzhou mandarin whose soil moisture is kept at the field capacity level is 979mm, and the total daily evaporation is 5.7-6mm in summer and 0.5-0.9mm in winter. If there is continuous drought, the number of fallen leaves will increase and the fruit will stop growing.

Easy to encounter typhoons and torrential rains in autumn will cause stagnant water in the park, so it should be drained as soon as possible. Otherwise, the decrease of root absorption will also lead to the shedding of young fruits.
