Cultivation techniques of areca catechu
Garden 1
Areca catechu is a tropical rain forest crop, and its soil requirements are not strict. Generally, it can be planted in mountainous areas, marginal areas and low wetlands below 300 meters above sea level in Hainan Province. Mountain preparation should be cut and weeded before the rainy season. In mountainous areas where the slope exceeds 15, it is necessary to dig a line around the mountain with an inward inclination of about 15 along the contour line.
Step 2 plant
Seedling selection: after 1-2 years of cultivation. Healthy seedlings with 5-6 green leaves and a height of 60- 100 cm were selected for planting.
Planting requirements: Generally, it is planted in March-April in spring and August-September in autumn, with the best planting in rainy season in August-September. Row spacing is 2.5-3.0m, plant spacing is 2.0-2.5m, and planting is 1500- 1650 plants/hectare.
3. Management and protection
Weeding and soil improvement: After the betel nut plant survives, shrubs should be cut down in time, leaving annual revolutionary vegetables and other leafy weeds to cover the ground, keeping the soil moist, which is beneficial to the growth of betel nut. Generally, weed 2-3 times a year and cover the soil 3-4 times to promote root growth.
