A special ridging and grooving machine for shallow yam planting method

Abstract

The invention relates to a yam shallow planting method and a specialized ridging groove-pressing machine, and belongs to the technical field of agricultural technology. The method comprises the steps of performing land preparation and fertilizer application, performing ridging and groove pressing, arranging grooves and sowing seeds, performing earthing and covering the seeds, and performing field management. The specialized ridging groove-pressing machine comprises a frame which is supported on land wheels, a rotary-tillage ridging assembly which is located in front of the frame, and a groove-pressing roller which is located at the rear part of the frame; and the groove pressing roller is aslant supported on the frame in a direction corresponding to a ridge shape formed by rotary-tillage ridging, and is equipped with arc protuberances which are corresponding to planting grooves with arc bottoms, are uniformly distributed along a circumferential direction and are extended along an axial direction. The method provided by the invention is adopted to change the growing direction of yam, and is beneficial for realizing whole-process mechanization of ploughing, planting, managing and harvesting of the yam; the machine has two functions of ridging and pressing grooves, not only is beneficial for reducing the labor intensity, but also is beneficial for guaranteeing the planting quality.

Description

technical field [0001] The invention relates to a planting method of Chinese yam, in particular to a planting method of superficial Chinese yam, and also relates to a special-purpose ridge forming machine, which belongs to the technical field of agricultural planting. Background technique [0002] Yam is a perennial herb with winding perennial roots. It belongs to the genus Dioscorea in the family Dioscoreae. Commonly used traditional methods for yam propagation are the reed head propagation method and the zero-surplus seed breeding propagation method. In the harvesting process of this type of traditional method, the digging pit is deep and easy to break, labor-intensive and time-consuming. Therefore, in recent years, planting in shallow troughs has become a trend. This planting method has changed the growth direction of yams and is conducive to the full mechanization of plowing, planting, management, and harvesting of yams. [0003] Retrieval shows that the Chinese patent...

Problems solved by technology

[0004] The Chinese patent document with application number 201410681785.3 discloses a special planting method of yam, including soil selection, ridging, ditching, seed selection, seed drying, germination, transplanting, stand support, fertilizer and water management, pest control, and harvesting. Although the oblique cultivation technology of shallow troughs is adopted, yams of any length can be planted, but the staggered planting of yams on the ridges has the following disadvantages: 1) the planting density of yams is reduced, and the yield is reduced; 2) the yams on the ridges Skewing is not conducive to the mechanization of groove pressing and swinging in the planting process, and it is also not conducive to the mechanized harvesting of yam

Although the deep-layer cultivation of horizontal growth is also changed to shallow-layer cultivation, which saves labor costs and is conducive to tuber expansion; and the conventional guide groove cultivation technology is changed to large ridges and double rows, which is conducive to soil moisture conservation and full use of light, and the ventilation effect between rows is good. but its disadvantages are: 1) the manufacturing cost of bamboo is higher, which increases the planting cost; 2) the output of bamboo is limited, which is not conducive to large-scale promotion, and a large amount of bamboo is not conducive to protecting the ecological environment; 3) the outer diameter of bamboo The size is different, which affects the appearance of the yam; 4) The heaviest links such as ridge lifting and groove pressing have not been mechanized
