Fine selection of citrus varieties, strict control of pests and diseases

Varieties in Hunan, Zhejiang and other places, some of the poor quality of medium-maturing varieties will be abandoned or replaced by high-quality varieties; Wenzhou oranges and glutinous rice dumplings??

In terms of cultivation, with the exception of citrus and citrus cultivation areas, there will be no significant increase in the input of citrus orchards in most producing areas; between yield and quality, more emphasis will be placed on improving quality; grass cultivation, simple pruning, simple fertilization, and pipe network Irrigation or drip irrigation and other labor-saving cultivation areas will be expanded; a number of standard orchards or fine orchards of advanced cultivation techniques will emerge, but the area of ​​orchard-deprived orchards will also expand; the area of ​​newly-built fruit orchards will decline, but the density of replacements and exchanges will increase. ; The cultivation of facilities will be expanded and the area for delayed harvesting will be expanded; the cultivation of green, organic and HACCP and related certifications will be gradually taken into account.

The processing and post-harvest treatment of post-harvest citrus fruit will improve the safety and freshness of citrus, improve the appearance of citrus, and reduce the loss of decay. Citrus processing and comprehensive utilization focuses on the relationship between citrus varieties and juicing performance. According to the types of raw materials, different processing methods are adopted; Citrus processing series products with certain commercial value are developed to increase the utilization rate of citrus fruits. More than 90.

The prevention and control of pests and diseases is particularly severe in the prevention and control of citrus yellow worm disease, ulcer disease and fruit fly pests. Huanglong disease has spread and spread along with the migration of hibiscus; maggots, whiteflies, thrips, crickets, and locusts tend to weigh heavily. Diseases caused by fungal diseases will tend to be heavier; damages caused by non-insect-borne grafting diseases are generally lighter.

With respect to mechanization, with the improvement of citrus sales in 2009, the confidence of fruit growers in citrus production will increase, and the demand for citrus production machinery and facilities will increase. The economic recovery will attract more young people to work in cities, and the lack of rural labor force will affect the citrus production machinery. The demand for facilities and facilities will further increase; on the other hand, it will stimulate the production of machinery and facilities to increase input and expand production; the testing, demonstration and promotion of science and technology projects in citrus machinery and facilities will radiate and lead the development of mechanized citrus production.

The economical centralized and large-scale production layout pattern will be strengthened; the variety structure and maturity structure will be further improved; fine orchard construction and standardization management will be fully implemented; labor and mechanization of cultivation and production will be further strengthened; and post-harvest commercialization The processing and deep processing capabilities have been further enhanced; the degree of organization and industrialization continues to increase; the proportion of fresh sales is too large, and sales of citrus fresh fruit are still difficult.
