Cultivation method of longan

Abstract

The invention relates to a cultivation method of longan, which comprises the following steps: A. setting the row spacing of the fixed planting pit position to be 1.5-2.5 m and the line spacing to be 2-5 m; B. digging the fixed planting pits; C.applying a fertilizer to the dug out mellow soil according to each strain; and then filling back the mellow soil with the clay fertilizer to enable the immature soil to be filled back on the mellow soil; D. digging the fixed planting holes on the central position of the fixed planting pit soil surface; pouring water into the fixed planting holes; when the water is completely infiltrated, placing seedlings of longan in the fixed planting holes; E. paving a mulching film after fixed planting; F. spraying monopotassium phosphate to leaves; G. cutting each seedling to be 80-100 cm in height; and leaving 4-6 directional main boughs on each seedling; and H. setting the row spacing at the fifth year after the fixed planting to be 3-5 m, and at the seventh year to be 4-6 m. With the adoption of the cultivation method, the earlier-stage yield and the output value of longan can be effectively improved; the investment cost recovery period can be shortened; and the anti-risk capability of the project can be enhanced.

Description

technical field [0001] The invention relates to the field of plant cultivation, and more particularly to a cultivation method of longan, which is suitable for the application of longan cultivation in a wide range of areas and varieties. Background technique [0002] Longan is one of the tropical fruit varieties in my country. Its pulp has antioxidant, anti-anxiety, anti-cancer, lipid-lowering, heart-protecting and antibacterial effects. And longan meat can be processed into convenient edible longan ointment, delicious fruit juice and health wine with certain effects. And gradually it has developed from a single fruit consumption to the intensive processing of health food, and the market development prospect is very broad. However, according to the current international fruit variety economic cycle of 10 years, there are two major technical defects due to the current design specifications for planting row spacing. That is to say, the first is to increase the yield per plant...

AI Technical Summary

Problems solved by technology

That is to say, one is to increase the yield per unit by traditionally increasing the yield per plant, which leads to the low yield in the early stage under the premise of planting row spacing, and the investment payback period is as long as 8 years. The investment risk of eliminating varieties has seriously restricted the rapid transformation and development of my country's longan industry to industrialized industries; second, because the current planting plant row spacing has not been considered, how to increase the initial yield, shorten the investment cost recovery period, and ensure that it will be carried out in about 10 years. Timely variety replacement and updating, design scientific plant row spacing, can not be updated in time when the variety should be updated, resulting in farmers and enterprises increasing production but not increasing, most social capital is unwilling to invest in agriculture, always thinks that agricultural investment is too risky, which seriously restricts the health of longan in my country develop
