“…The BM provides a higher tensile strength of 7.71 ± 1.21 MPa. One fascinating fact that came out from the mechanical property investigation was the high tensile strength of the BM compared to MIL, which is in total disagreement with the one proposed by Tang et al, 43 which says that succulent or fresh leaves tend to have a higher tensile strength than biofabricated materials. The MIL has a tensile strength of 5.4 ± 1.23 MPa, which shows lesser tensile strength than BM.…”

Water is one of the most important and crucial indicators of sustainable development goals (SDGs) for humans and other living organisms. Water demand has outstripped supply, resulting in shortage on a worldwide scale, particularly in arid regions. This water scarcity has impeded agricultural productivity and other developmental projects with the ongoing global warming and other anthropogenic activities making it more complicated. To address the worldwide water crisis, it is worthwhile to convert atmospheric air to drinking water. Sequel to that, a hydrophobic surface was designed using facile lithography to compare its water harvesting efficiency with a hydrophilic surface at different orientation angles. For the research, the hydrophobic designed surface is called biodesigned material, while the hydrophilic natural surface is a Mangifera indica leaf (MIL). It is against this background that we seek to investigate the most suitable orientation angle good for efficient water harvesting. To that end, a 60° inclination angle is the most efficacious orientation for water collection as it outperformed the 30 and 45° orientation angles. To minimize re-evaporation, absorption, suction, and other environmental challenges that impede efficient collection, atmospheric moisture should be collected immediately from functional surfaces.

“…For example, when rice leaves were dried by microwave, the cell wall is broken, which would change the tensile breaking property. Tang et al [40] carried out the tensile test of rice leaves under different temperatures and moisture. The results showed that moisture content had a greater impact on rice leaf breaking property.…”

In order to fight for good farming time or harvest in bad weather, combine harvester will produce more broken leaves when threshing high moisture content rice, which will seriously hinder the grain cleaning effect. In this study, the breaking behavior of rice leaves under different microwave drying time and drying power was studied. Firstly, based on the appearance of freshly rice leaves undergoing microwave drying, the changing property of moisture content, weightlessness rate and temperature rise of rice leaves were tested and analyzed. Secondly, the tensile breaking force of freshly rice leaves under different microwave drying time and drying power was tested and compared with the tensile breaking force of naturally dried rice. Finally, the optimal microwaves parameters of rice leaves after drying which could result in greater breaking force than the natural drying state were obtained. The result showed that microwave drying method will reduce the moisture content of rice leaves and change the microstructure, which would affect the tensile-breaking property of rice leaves. The maximum tensile breaking force of rice leaves appeared at microwave dried power 70 W for 5-8 min and at microwave dried power 210 W for 3-4 min. The tensile breaking property of rice leaves at microwave dried power 350 W for 6-8 min were the weakest, which was lower than that of fresh rice leaves. Therefore, the optimal microwave drying parameters of rice leaves will provide a basis for the application of microwave technology in the threshing process.

“…The stalks of wheat are divided into above-ground part and underground part.The stalks of the underground part have secondary roots at the tiller nodes, and the stalks of the above-ground part are covered with leaf sheaths. The stalks of the above-ground part are generally 4-6 nodes, and the structure is similar to that of barley, rice and reed[18] . Support and transportation are two main functions of stalks.…”

During the baling operation, the wheat stalks are subjected to various mechanisms in the baler and the main form is compression. After the wheat stem is forced by a combination of the threshing cylinder, it needs to be formed under the action of straw baler and meet transport requirements. This paper mainly studies the properties of wheat stalks when baling, and proposes the application of the creep after-effect theory during the baling process. The tension-compression tester was used to perform a 50 mm stalk mechanical test, 50 mm stalk static pressure test, 35 mm×40 mm×50 mm stalk module static pressure test and bale static pressure test. The measured elastic modulus of the stem sample was 7.59 MPa, and the elastic modulus of the inner core of the stem was 8.24 MPa. The return curve of the single stalk and the bale is consistent with the initial creep and steady-state creep in the creep after-effect theory. A logarithmic function was used for fitting of the first stage with coefficient of determination R 2 = 0.8364, and a linear function was used for fitting of the second stage with coefficient of determination R 2 = 0.9921. The high water content static pressure test suggests that the load in the loading direction is the coupled load of the working load of the hydraulic cylinder and the internal stress of the bale. When harvesting wheat stalks with high moisture content, the density parameter of the bale can be appropriately increased while the load parameter of the hydraulic cylinder can be considered unchanged or even reduced. The adjustment of density and load can still ensure the forming quality of the bale.
