“…When they work together, seeds can be deposited into the seed ditch quickly and precisely [5][6][7][8] . However, the main factors that influence the sowing performance are the seed bounce and collision in a high-speed seed guiding device [9] . The degree of bounce and collision also rises as the working speed increases, which has a significant impact on the seedthrowing accuracy.…”

Seeding is an important part of improving corn yield. Currently, seed guide tubes are mostly used as transport devices. But the existing seed guide tubes cannot meet the requirements or achieve the goal of fixing the seed falling trajectory. A seed collision phenomenon occurs occasionally. So, in response to the problems that the seeds and seed guide tube collide or bounce under high speed operation, which results in a lower sowing qualification rate and poor spacing uniformity, a seed receiving and conveying system comprising a belt-type high-speed corn seed guiding device was designed and optimized, to meet the needs of high-speed precision sowing operations and improve the spacing uniformity.The factors affecting the seed conveying performance were obtained by analyzing the mechanical properties of the seeds at various movement stages. These factors were the number of seed cavities between adjacent seeds, the forward speed, the height from the ground, and the installation angle. Single factor simulation experiments were conducted by selecting the paddle spacing as the test factor and using the pass rate, reseeding rate, omission rate and coefficient of variation as the evaluation indexes to investigate the influence of the paddle spacing on the seed guide performance of the device and further determine the structural parameters of the paddle belt. Orthogonal rotation combination tests of three factors and five levels were also conducted through bench testing.Then the test outcomes were optimized. The results indicated that the best results were obtained when the number of seed cavity intervals between adjacent seeds was 5.16, the installation angle was 79.40°, and the height from the ground was 31.84 mm. At this time, the qualified rate was 98.49%, the repeated sowing rate was 0.48%, the missed sowing rate was 1.03%, and the coefficient of variation was 6.80%. Experiments were used to validate the optimization results, and all of the obtained index data satisfied the criteria for accurate and quick corn sowing. The study's findings can serve as a theoretical foundation for a belt-type high-speed corn seed guiding device optimization test.

“…Potato breeding experiments are divided into asexual firstgeneration, second-generation, and third-generation selection, preliminary line comparison, and line comparison experiments [4]. The harvesting requirements of potato breeding trials are different from those of the field [5]. Taking the most cautious period of harvestasexual generation-as an example, different plants in the same row in potato breeding experiments have different hybrid offspring.…”

In order to solve the current problems of time-consuming manual work and low harvesting efficiency during the harvesting of potato breeding trials and the inability of traditional harvesting machinery to meet the requirements of potato single plant harvesting, a single plant harvester for potato breeding with a combined excavation device and a conveying and separating device with alternating concave and straight units is designed. This paper analyzes the force, motion, and collision of potato plants in the digging transition stage and conveying and separating stage. The key factors affecting the rate of single plant integrity and the rate of injured potatoes are determined. A three-factor quadratic regression orthogonal rotating combination experiment is conducted with the rate of single plant integrity and the rate of injured potatoes as experiment indexes, forward speed, conveying speed to forward speed ratio, and the rotational speed of the rear-vibration device as influencing factors. Based on the experiment results, a mathematical regression model is established, and response surface analysis and parametric analysis are conducted to determine that when the forward speed is 0.65 m∙s−1, the ratio of conveying speed to forward speed is 0.98, and the speed of the post-vibration device is 11.52 rad∙s−1, the single plant integrity rate is 97.14% and the rate of injured potatoes is 0.67%. The machine can better meet the requirements of potato single plant harvesting and solve the problem of plant mixing. From the perspective of potato damage rate, potato breeding harvesters are also suitable for traditional potato harvesting.

“…Due to the unique climatic factors and soil conditions, northern Shaanxi plays an irreplaceable role in potato production ( Xing et al., 2020 ). However, there are many problems in potato production in this region, such as over irrigation and fertilization, improper selection of varieties ( Wang et al., 2019b ; Wang et al., 2021b ; Zhou et al., 2022 ). These problems have worsened the soil micro-ecosystem and limited the development of the potato industry in the region.…”

The effects of different irrigation and fertilization on potato yield, soil fertility and soil enzyme activity of different varieties under drip irrigation fertilization mode were studied, which could provide support for selecting the best varieties in Northwest China. Three factors and three levels orthogonal experimental design method, a total of nine treatments. The three irrigation levels were W1 (100% crop evapotranspiration (ETC)), W2 (80% ETC) and W3 (60% ETC). The three fertilization levels were F1 (N-P2O5-K2O, 240-120-300 kg ha−1), F2 (180-90-225 kg ha−1) and F3 (120-60-150 kg ha−1). The three varieties were V1 (Feiuritar), V2 (Longshu7) and V3 (Qingshu 9). The results showed that different irrigation and fertilization had significant effects on potato yield, soil fertility and soil enzyme activity in root zone. The highest yield of T5 (80%ETC, 180-90-225 kg ha−1, Qingshu 9) was 49,222.3 kg ha−1. With the increase of fertilizer application rate, potato yield and soil enzyme activity in root zone increased first and then decreased, but soil electrical conductivity (SEC), soil nitrate-N content (SNNC), soil alkali-hydrolyzable nitrogen content (SAHC), soil available potassium (AK), soil available phosphorus (AP), soil ammonium-N content (SANC) and soil organic matter (SOM) in root zone increased continuously. The yield, soil catalase activity, soil urease activity and soil sucrase activity at W2 were 2.81% and 22.2%, 1.84% and 7.04%, 8.26% and 9.62%, 5.34% and 13.36% higher than those at W1 and W3, respectively. The overall trend of soil water content, soil nutrient content and enzyme activity in root zone was 0–20 cm >20–40 cm >40–60 cm soil layer. There were many soil factors affecting tuber yield, among which soil enzyme activity, pH value and root zone conductivity were the key factors. The results showed that T5 (80%ETC, 180-90-225 kg ha−1, Qingshu 9) was the best treatment to improve soil enzyme activity and yield.
