Abstract:
... As a low-cost and light-weight flexible rope, the production and use of straw rope can promote the transformation of straw into industrial raw materials and improve the utilization rate of straw. However, non-standard production makes the straw rope prone to failure and breakage. In this paper, the Chinese Zhendao 10# variety was selected, and mechanical tests were carried out on the components of ...
... Increasing planting density is among the most effective ways to increase soybean yield, but high planting density increases lodging risks in soybean plants. To examine the effects of shading on soybean plant lodging, the tall cultivar Heinong 48 (HN48) and dwarf cultivar Henong 60 (HN60), two soybean cultivars with large plant height differences (approximately 40 cm), were selected, and their inte ...
... Eucalyptus (including Eucalyptus grandis) is an excellent wood forest tree species that provides a large number of plant fiber raw materials for the paper and timber industries. Cellulose, an essential structural component in plant cell walls, is a renewable biomass resource that plays a very important role in nature. There is still a lack of research on the role of gene regulation in cellulose sy ...
... Rapid and efficient clean-up of viscous crude oil spills is still a global challenge due to its high viscous and poor flowability at room temperature. The hydrophobic/oleophilic absorbents with three-dimensional porous structure have been considered as a promising candidate to handle oil spills. However, they still have limited application in recovering the high viscous oil. Inspired by the viscos ...
