山药不挖沟栽培技术(国外英文资料) The mountain medicine does not gouge the technique First, plastic casing cultivation technique (1) processing plastic casing Use the inside diameter of 6 ~ 7 centimeters of hard plastic tube, use saw cut section, each paragraph is 80 ~ 100 centimeters, and the longitudinal division long seam, the seam width is about 0.5 centimeters. Then the port is cut to the port 20cm at the end of the tube, and the cut is semi-circular. At the other end of the plastic tube to the center of the hole (using the electric drill), the aperture is 1 centimeter, the spacing is 3 centimeters, each row 6 holes, 4 rows. A casing can be used for six to eight years. (2) digging trenches to bury the casing Deep 40 ~ 50cm deep (100cm).
