Integrated Design and Evaluation of a Soil-Covering and Film-Mulching Device for Sugarcane Transverse Planters

Abstract

To solve the problem that the covering device of sugarcane cannot be adequate for the agronomic standards of seed cane setts planting, a soil-covering and film-mulching device for sugarcane transverse planting was designed. The device includes a soil-covering part, soil-compacting part, and film-mulching part. Through theoretical analysis of key components, the factors affecting the cane seed covering quality for the device were obtained. A quadratic orthogonal rotation regression test was conducted by a homemade prototype to explore the effects of disk diameter, central distance, disk depth in soil, and dip angle on soil covering thickness. The results showed that the above factors all have an extremely significant effect on the soil covering thickness, and the effect degree of each factor from high to low is central distance, disk depth in soil, dip angle, and disk diameter within the range of test parameters. The optimal parameter combination, with the disk diameter, the dip angle, the central distance, the disk depth in soil, and the diameter of the soil-compacting wheel being 304.7 mm, 55.1°, 386.5 mm, 32.4 mm, and 300 mm, respectively, was obtained by Design-Expert software and verified by comprehensive field tests. The results showed that the covering thickness is in the range of 94–111 mm, the average value is 102.6 mm, and the breakage rate is no more than 2.6%. The emergence rate is 86.4%, which is an improvement of 9.3% over that of a traditional covering device. The results suggested that the device can conform to the agricultural covering standard of sugarcane planting and provide a design basis for the application and popularization of the soil-covering and film-mulching device.

Technological advancements in mechanized sugarcane cultivation applicable to familiar farming: influences on sdg. A review

“…Thus, advances with those presented by (Wu et al 2020;Kumar et al 2018;Zhou et al 2020;Wu et al 2021;Hu et al 2021;Li et al 2021;Shahare et al 2021;Qiu et al 2021;Chander and;Kumar 2021;Birajidar et al 2019;Singh and Singh 2017;Khaehanchanpong et al 2017) have overall observations ranging between 81 and 100%, with the TRL ranging between 6 and 9. So, many advanced technologies meet all the criteria for technological advances applicable to family farming and are at a favorable stage of technological development.…”

Numerical simulation and experiment of the emergence of young potato sprouts through soil‐covered plastic mulching

“…From this consideration alone, it is therefore recommended that the thickness of the soil covering the film to be between 20 and 70 mm because for longer film breaking time the seedling burning rate increases. On the other hand, if the soil is tightly compressed, the resistance of breaking by the potato sprout increases, which is harmful to budding (Hyatt et al., 2007; Li et al., 2021). From this other consideration, the minimum resistance to the growth of the potato seedlings observed for 40 mm of covering soil thickness appears to be the best choice.…”

“…As the value of Ahyp increases, the deviation degree of yield surfaces increases, while for Ahyp = 0, it becomes the standard Mohr‐Coulomb yield criterion. To ensure accuracy (Abbo & Sloan, 1995; Li et al., 2021), Ahyp should not exceed C × cot( ϕ ), with the recommended value being: $$$$\begin{equation}Ahyp = {{C\cos \left( \phi \right)} \mathord{\left/ {\vphantom {{C\cos \left( \phi \right)} {20}}} \right. \kern-\nulldelimiterspace} {20}}\end{equation}$$$$…”

Design and Field Test of a Leaping Type Soil-Covering Device on Plastic Film

“…In order to meet the agricultural requirements of potato planting with whole-film mulching and soil covering in the row in the northwest arid area of China, a leaping type of soil-covering device was designed. Compared to traditional soil-covering machines [16][17][18][19], this device can obtain soil from the front of the plastic film and lift it over the film-covering device. There is no bare soil belt between adjacent plastic films to ensure ground temperature.…”

“…The machine can loosen soil and weed and raise soil in one operation. Li [17] and other researchers developed a sugarcane horizontal planter with a soil-covering disc at the rear. As the planter moves forward, the disc rotates and the soil on the disc surface flows to the center of the ditch.…”
