The resuIts showed that mechanical harvesting technoIogy increased the yield of 92.7 kg/hm2, reducing the seeds Ioss. It improved the Iabor efficiency and reduced the harvesting cost. For exampIe, a rice combine harvester was the equal of 18-20 person in the harvest quantity in one day, which directIy reduced the Iabor cost of 2 175-3 000 yuan/hm2 and increased the economic income of 3 307-4 099 yuan/hm2. So it wiI pIay an important roIe in soIving the shortage of Chinese miIk vetch seeds and ac-ceIerating the deveIopment of Chinese miIk vetch green manure crop in south China rice region.展开更多

Membranaceus Munro) andtheir physical and mechanical properties have been studied in the paper. The results showed that the whangee hasbetter physical properties than that of the Yunnanicus, such as higher density, lower tangential and longitudinal dryshrinkages. That also showed that Whangee has stronger mechanical properties in MOR and MOE, compressivestrength and shear strength parallel to the grain. Compared with some wood species used in architecture, the physicaland mechanical properties of the two kinds have reached the requirement of some wood architecture structurematerials.展开更多
