Cultivation method for citrus sinensis

Abstract

The invention belongs to the technical field of agriculture and discloses an early-maturing cultivation method for oranges. It includes the following steps: (1) Grafting and growing seedlings: the rootstock sowing period is early and mid-December, and the scion is sown 7 to 12 days later than the rootstock; (3) Control temperature; (4) Pruning: use double or three pruning methods; (5) Artificial pollination and fruit retention: the second female flower of the main vine and the first female flower of the side vine are artificially opened. Pollination; (6) harvesting. The harvest period of the early-maturing oranges cultivated by the method of the invention is advanced to the middle and late April, which is 20 to 30 days earlier than the current greenhouse cultivation, and the harvest period avoids the rainy season in southern regions, thereby ensuring high and stable yields. It not only meets the market demand, but also greatly improves the output and economic benefits.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to an early ripening method for oranges. Background technique [0002] With the improvement of people's living standards, the consumption structure and diet concepts are constantly updated. People's consumption demand for oranges is no longer mainly based on quenching summer heat and thirst, but the pursuit of quality, characteristics, annualization and diversification. High quality, outstanding commodity, and the listing period is as long as 8 months, which is in line with people's consumption habits, and is very popular with consumers, and the demand is increasing day by day. The huge consumption market of oranges has promoted the adjustment of the planting structure of oranges. At the same time, oranges have a short growth period and are suitable for diversified cultivation. Generally, every 667m 2 The output is 2500kg~4000kg, and the market sales price can be as high as ...

Problems solved by technology

[0003] However, the orange seeds are small and expensive, and the seedling growth potential is weak. The requirements for temperature, light, water and fertilizer in each growth period are relatively strict, and the weight of a single fruit is only 1-2kg. Therefore, it is a large-scale and standardized production to increase the yield and quality and to market early. and the basis for development

However, there are many problems in the current production, such as high investment in early-maturing cultivation, natural conditions in early spring (low temperature, continuous rain, etc.) are not conducive to the normal growth of oranges, the current cultivation method is relatively late in the market, the yield in the early stage is not ideal, and the rainy season coincides with the later period, etc. etc. There is still a lot of room for improvement in terms of planting efficiency

[0004] At present, the method of greenhouse + small shed is adopted in the early-maturing cultivation of oranges, and the yield and output value are somewhat higher than those of open-field cultivation. The market period is mid-to-late May. The cultivation environment is high temperature and high humidity during the fruiting period, and soil-borne diseases occur seriously. During the rainy season, large losses are often caused
