Abstract:

In order to clarify the current situation of citrus fertilization in Zhejiang Province, analyze the differences of farmers’ fertilization levels, and explore the path of scientific nutrient management of citrus, this study investigated 367 planting entities in Zhejiang Province in 2024. The survey content includes fertilizer types, fertilizer dosage, application time, application methods, sowing area, farmers’ information, etc., and analyzed the citrus fertilization level with reference to the current Zhejiang fertilizer application limit standard. The results showed that the fertilization level of citrus in Zhejiang Province tended to be scientific and reasonable, and the average amount of chemical fertilizer decreased significantly, but there were also some problems, such as the low proportion of organic fertilizer and formula fertilizer, conservative fertilization methods, and huge differences in fertilizer use among different planting subjects. In the future, we still need to continue to strengthen the policy support of organic fertilizer and formula fertilizer, increase the subsidy of efficient fertilization machinery, and do a good job in scientific fertilization policy and technical training and promotion for small and medium-sized farmers.

Key words: citrus, current status of citrus fertilization, formula fertilizer, organic fertilizer, Zhejiang Province
