An early maturing cultivation method for dimocarpus longan

Abstract

The invention belongs to the technical field of agriculture and discloses an early-maturing longan cultivation method. It includes the following steps: (1) Grafting 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 the 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 longan 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-maturing longan cultivation method. Background technique [0002] With the improvement of people's living standards, the consumption structure and diet concepts are constantly updated. People's consumer demand for longan is no longer based on quenching summer heat and thirst, but the pursuit of quality, characteristics, annualization and diversification. In recent years, longan varieties with a fruit weight of 1-2kg have good taste, high quality, The commodity is outstanding, 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 longan has promoted the adjustment of longan planting structure. At the same time, longan has a short growth period and is suitable for diversified cultivation. Generally, every 667m 2 The...

Problems solved by technology

[0003] However, longan seeds are small and expensive, and the growth potential of the seedlings is weak. The requirements for temperature, light, water, and fertilizer are relatively strict in each growth period, and the weight of a single fruit is only 1-2kg. foundation of 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 longan, 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 stage, etc. , there is still a lot of room for improvement in planting efficiency

[0004] At present, the early-maturing cultivation of longan adopts the greenhouse + small shed covering method, and the yield and output value have been improved compared with open field cultivation. The market period is in the middle and 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
