Abstract

Subsoiling has been widely used all over the world as an important operation method of no-tillage farming. For energy-saving and life-extension, the tillage resistance and wear-corrosion of subsoilers have attracted wide attention. In this study, the tillage resistance, soil disturbance, wear and corrosion of subsoiler with S-T-SK-2# biomimetic structures (S means subsoiler; T means tine; SK means shank; 2#, h/s=0.57, h=5 mm and α=45°.) and self-healing coating under two seasons, two locations with different soil properties (black loam and clay soil) and subsoiling speeds (2 km/h and 3.6 km/h) were investigated. The soil moisture content and compactness affected the tillage resistance and wear-corrosion. The tillage resistance and degree of corrosion on all subsoilers were much larger in clay soil than that in black loam soil. Compared with S-T-SK-2#, the tillage reduction rate of C-S-T-SK-2# (S-T-SK-2# with self-healing coating) was up to 14.32% in clay soil under the speed of 2 km/h. The significance tests of regression equation results showed that subsoiler type and soil properties had a significant impact on soil disturbance coefficient, swelling of total soil layer, bulkiness of the plough pan. It is of a guiding significance for the analysis of soil disturbance. Synergism mechanism of subsoiler coupling with biomimetic structures and self-healing coating was analyzed in following. It depicted the guiding effect of biomimetic structure and the shield function of self-healing coating, resulting in anticorrosion and wear resistance of subsoiler.

自修复仿生深层土壤对不同土壤类型下土壤抗耕性能、耐磨性和扰动形态的影响

深埋作为一种重要的免耕耕作方式，在世界各国得到了广泛的应用。为了节能和延长使用寿命，深耕器的耐耕性和耐磨性引起了人们的广泛关注。在本研究中，S- t - sk -2#仿生结构的深耕器(S表示深耕器;T表示时间;SK是指柄;2#， h/s=0.57, h=5 mm， α=45°)，在2个季节、2个土壤性质不同的地点(黑壤土和粘土)和2 km/h和3.6 km/h的沉土速度下，对自愈涂层进行了研究。土壤含水量和密实度影响土壤的耐耕性和耐磨性。土中土壤的抗耕性和腐蚀程度均大于黑壤土。与S-T-SK-2#相比，在2 km/h的速度下，C-S-T-SK-2#(带自愈涂层的S-T-SK-2#)在粘土中的减耕率可达14.32%。回归方程结果的显著性检验表明，土壤类型和土壤性质对土壤扰动系数、全土层膨胀、犁盘体积有显著影响。对土壤扰动分析具有一定的指导意义。分析了深层土壤与仿生结构和自愈涂层耦合的协同作用机理。描述了仿生结构的引导作用和自愈涂层的屏蔽作用，从而实现了土壤的防腐耐磨。关键词:土壤类型，抗耕性，磨损腐蚀，土壤扰动，自愈DOI: 10.25165/ j.j ijabe.20231603.7876引用本文:王永明，卢春江，陈健，崔春华，潘玉杰，Pfleging W，等。自修复仿生深层土壤对不同土壤类型下土壤抗耕性能、耐磨性和扰动形态的影响农业与生物工程学报，2023;16(3): 7 - 14。
