A De-Seeding Machine Designed for The Fruit Structure of Pseudo-Acid Pulp

Zhangmao Li — 2025-05-15

As a characteristic economic crop, false acid pulp has high medicinal value, as well as certain edible and ornamental value. Because of the strong stress resistance of the plant and the simple planting, the price of the seeds of the pseudo-acid pulp has remained high in recent years, so the planting area has increased. However, due to the special fruit structure, the de-seeding of the pseudo-acid pulp is difficult and mainly relies on manual work. This project plans to design a small de-seeding machine for the fruit structure of pseudo-acid pulp. The de-seeding work of pseudo-acid pulp is completed by extrusion, kneading and vibration screening, which has a good application prospect.

A Discourse Progress Analysis in The Human Stain from the Lacanian Perspective

Hangfei Yu — 2025-05-15

This thesis pays attention to the application of Lacan’s theory of psychoanalytic discourse in four main characters in The Human Stain through close reading. The thesis finds out that the four characters represents four Lacanian discourses. Specifically focusing on the two women characters, the thesis points out the progress from Delphine to Faunia with its deconstruction of knowledge and love. Finally, the thesis raises possible measure to get the progress, which is meaningful to modern people, especially women.

Characteristics of Greenhouse Gas Emissions from Alpine Farmland in Qinghai Province

Chengqi Liu — 2025-05-15

In order to better study the effects of fertilizer application on alpine farmland in Qinghai Province, the effects of fertilizer application on greenhouse gas (CH4, CO2 and N2O) emission fluxes and global warming potential of alpine farmland were studied by static chamber-meteorological chromatography method by static chamber chromatography method, and the trend of greenhouse gas emissions from alpine farmland in Qinghai Province was further analyzed. The results showed that the total CO2 emissions of each treatment increased by 24.75%, 1.5N and M by 24.75% and 74.21% compared with CK. Appropriate application of nitrogen fertilizer reduced N2O emissions, and the total emissions of treated N decreased by 48.59% compared with CK. The overapplication of nitrogen fertilizer promoted N2O emissions, and the total emissions increased by 49.56% compared with CK treatment. The application of organic fertilizer can effectively reduce N2O emissions, and the total emission of M treatment is reduced by 97.41% compared with CK. The application of nitrogen fertilizer and organic fertilizer could promote CH4 emissions, and compared with CK, treatment N increased by 70.25%, treatment 1.5N increased by 143.31%, and treatment M increased by 159.58%. Compared with the treatment of CK, the GWP of treatment N, 1.5N and M increased by 175.46%, 341.59% and 445.36%, respectively. The results showed that the application of nitrogen fertilizer and organic fertilizer could promote greenhouse gas emissions, and the degree of promotion treatment M > 1.5N > N > CK. The global warming potential is mainly due to CO2 and CH4, while the contribution rate of N2O is less than 0.5%.

Study on Seed Germination, Growth and Nutrient Release of Kentucky Bluegrass in Pressed Granulated Grassland

Minghao Zhao — 2025-05-15

The effects of pelleted pelleting on seed germination, growth and nutrient release of Kentucky bluegrass were investigated. By comparing the seed germination rate, germination potential and seedling growth index of different pelleting, combined with the analysis of nutrient release in soil environment, the synergistic mechanism of pelleting and nutrient release was revealed. The results showed that F1 ( 80 % bentonite : 10 % organic fertilizer : 10 % sheep manure ), F2 ( 70 % bentonite : 15 % organic fertilizer : 15 % sheep manure ), F3 ( 60 % bentonite : 20 % organic fertilizer : 20 % sheep manure ), F4 ( 50 % bentonite : 25 % organic fertilizer : 25 % sheep manure ), F3 treatment can significantly improve seed germination time and growth height, and delay nutrient release rate. This study provides a theoretical basis for optimizing the pelleting process, and has practical significance for achieving precise quantitative seeding and reducing application efficiency.
