Growing ginger under the forest canopy

(Baonghean)In 2010, with the support of Nghe An Province Agricultural Extension Center, Ky Son District Agricultural Extension Station coordinated with local authorities to build a model of "Ginger planting under forest canopy", in Na Ngoi commune the model was deployed in the spring crop of 2012, with a scale of 1 hectare.

The model's objective: Intercropping short-term crops with long-term crops both limits erosion and increases income for people. On the other hand, the process of caring for short-term crops creates favorable conditions for long-term crops to grow well.

First is clearing the ground cover, the ground cover is cleared, chopped into small pieces to make mulch after planting, limiting erosion and leaching. The soil is made in strips, between the rows of main crops along the contour lines. Hoe the soil to a depth of 25 - 30 cm, then make rows, the rows are made to a depth of 15 - 20 cm (rows are 30 - 35 cm apart, clumps are 25 - 30 cm apart). The clumps between the upper rows are arranged in a crocodile tooth shape (tripod). In places with complex terrain, the soil is made in holes (50 x 50 x 25 cm), using a small hoe to mound the soil 5 - 7 cm high. The amount of fertilizer is calculated for 1 hectare (10 tons of decomposed manure + 400 kg of lime powder + 110 - 130 kg of urea + 400 kg of super orchid + 200 - 250 kg of potassium). Apply all lime powder when preparing the soil, apply all manure and 1/2 amount of inorganic fertilizer when planting, apply in rows and then cover with a thin layer of soil to cover the fertilizer to avoid the seeds coming into contact with the fertilizer. When planting, place the ginger sample at a depth of 3-4 cm so that the sprouts face up, then cover the ginger with fine soil, press firmly with your hands and then cover with soil.

If planting in holes, place 3 cuttings in each hole in a triangle shape (20 cm apart). After planting, use compost such as chopped vegetation, straw, rice husks... a thin layer to retain moisture and increase looseness. After 2 months of planting, weed and mound the base, after about 5 months, apply all remaining inorganic fertilizer; spread fertilizer evenly around and 5-7 cm from the base and combine with mounding the base.
