Is the weather in Hunan suitable for planting sugar oranges?

The weather in Hunan is suitable for planting Shatangju.

Planting conditions:

I. Permeable soil

In fact, it has a wide adaptability to loam and can be planted and grown in various soils. Require a sense of permeability, soft and loose texture, not clay loam with strong drainage, but also some organic matter. It is most suitable for growing in this loam, and the pH value is controlled at 5.5-6.5.

Second, the ambient temperature.

It is also necessary to ensure a good temperature range for planting. The temperature of the planting area is preferably within the range of 12-37 degrees Celsius, which is not suitable for planting and growing at high and low temperatures. Autumn is just in the flower bud differentiation period, and it is necessary to ensure a good temperature difference, at least 10 degrees Celsius, and maintain it at around 20 degrees Celsius during the day and 10 degrees Celsius at night.

Third, the degree of sunshine.

It is relatively shade-tolerant, but it also needs enough sunlight to promote growth. Sunshine conditions must be good, and the fruit will be sweet to eat. Under normal circumstances, the sunshine hours can grow normally in the range of 1200-2200, and the growth is no problem.

Fourth, the planting density?

The density varies with the variety and soil quality. The general planting density is about 80- 1 10 plants per mu.

Fertilization of Shatangju

1. Fertilization principle: To fully meet the demand of blood orange for various nutrient elements, it is advocated to apply more organic fertilizers and rationally apply inorganic fertilizers and formula fertilizers. According to the results of leaf analysis, orchard soil analysis and blood orange phenology, fertilization is guided.

2. Fertilization method: mainly soil fertilization combined with foliar fertilization. The methods of annular furrow application, strip furrow application, hole application and soil surface fertilization were adopted.

3. Fertilization of young trees: apply fertilizer thinly, mainly nitrogen fertilizer, supplemented with phosphorus and potassium fertilizer, and apply fertilizer 5-6 times in spring, summer and autumn at the seedling stage (March, May, June, July, September and 65438+February), with 0.4 kg of ammonium carbonate or 0.2 kg of urea applied to each plant each time. 1-3 young trees should be applied with pure nitrogen 100-400g every year, and the ratio of nitrogen, phosphorus and potassium is1.0: (0.4-0.5):1.0.

4. Adult trees should be fertilized four times, that is, germination fertilizer, fruit protection fertilizer, strong fruit fertilizer and fruit picking fertilizer. Generally, the amount of fertilizer applied is 2-3 kg of chemical fertilizer and one load of manure. Fruit-keeping fertilizer 1-2 kg phosphorus and potassium fertilizer+1 kg chemical fertilizer; Strong fruit fertilizer 1-2 kg chemical fertilizer+1-2 kg phosphorus and potassium fertilizer; The fruit picking fertilizer (base fertilizer) is mainly organic fertilizer, and each plant is applied with 50- 100 kg organic fertilizer+1-2 kg chemical fertilizer.
