Chinese yam directional cultivation device

Abstract

The invention discloses a Chinese yam directional cultivation device. Grooves of which the cross sections are semicircular are formed on the center line of the wall-thickness lower end face of an upper semicircular cylinder in the axial direction; semi-cylindrical raised lines which are matched with the grooves are arranged on the center line of the wall-thickness upper end face of a lower semicircular cylinder in the axial direction; the left end of the upper semicircular cylinder is aligned with the left end of the lower semicircular cylinder, thereby constructing a cylinder of which the cross section is circular; the inner wall of the upper semicircular cylinder and the inner wall of the lower semicircular cylinder are provided with high-hydroscopicity resin layers respectively; the length size of the upper semicircular cylinder is smaller than that of the lower semicircular cylinder, thereby forming a planting opening between the right end of the upper semicircular cylinder and the right end of the lower semicircular cylinder; outer-diameter end surfaces of a left part and a right part of the cylinder are sleeved with elastic rubber rings respectively. The Chinese yam directional cultivation device is suitable for directional cultivation of Chinese yam. By adopting the Chinese yam directional cultivation device, the labor intensity in planting and harvesting of the Chinese yam is lowered, root tuber tissues are prevented from being damaged, water and nutrient retention capability of the cylinder can be enhanced remarkably, the yield of the Chinese yam is increased, and the cylinder can be used repeatedly after harvesting of the Chinese yam.

Description

technical field [0001] The invention relates to the technical field of agricultural planting devices, in particular to a yam directional cultivation device. Background technique [0002] Yams are perennial herbaceous plants of the genus Dioscorea. The tuberous root of yam is cylindrical, and under natural conditions, it is vertically inserted into the ground, and the depth can reach 30-120cm. Because the root tubers of yam have such growth characteristics, there are the following problems in production: first, the thickness and size of the soil are particularly high, and deep digging and soil cultivation are required before planting, which is labor-intensive; second, harvesting is particularly troublesome and easy to harvest. Damage root tissue; the third is that the water and fertilizer conditions of the soil in many areas are limited, which affects the yield of yam. [0003] The patent bulletin discloses the authorized patents of the "yam cultivation guide" whose applica...

Problems solved by technology

Because the root tubers of yam have such growth characteristics, there are the following problems in production: first, the thickness and size of the soil are particularly high, and deep digging and soil cultivation are required before planting, which is labor-intensive; second, harvesting is particularly troublesome and easy to harvest. damage the root tissue; the third is that the water and fertilizer conditions of the soil in many areas are limited, which affects the yield of yam

These two technologies can reduce the labor intensity of yam planting and harvesting, and avoid damage to the root tissue, but they cannot significantly enhance the water and fertilizer retention capacity of the cylinder, and the cylinder cannot be reused after the yam is harvested
