The treatments of starting to use wind machines before tea sprouting,starting before frost occurrence and stopping after sunrise were set up respectively. And the impact of wind machine operation on the growth of tea trees,temperature rise in the canopy and protection coverage was measured. The results indicated that starting to use wind machines 20 d,15 d and 7 d before tea sprouting increased the length of young shoot,bud density and 100-bud weight by over 20% compared with the control test; Starting wind machines 2. 0 h,1. 5 h and 1. 0 h before frost occurrenceled to better protection and enlarged the coverage radius by more than 60% compared with the control test. Delayed stopping of wind machines by 2. 0 h,1. 5 h and 1. 0 h after sunrise reduced the temperature rise of the canopy by 45. 76% in the first hour,and narrowed the reduction of the photosynthetic intensity of tea leaves. Therefore,to protect tea trees from late frost cold for better growth and yield,the appropriate application of wind machines should be more than 7 d prior to the tea budding, and the operation timing of starting and stopping for a certain frost event should be 1. 0 h before frost occurrence and 1. 0 h after sunrise,respectively.","PeriodicalId":35080,"journal":{"name":"农业机械学报","volume":"24 1","pages":"252-257"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82390199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, several artificial landmarks were located in a simulating tunnel, and then a vision sensor in vehicle was used to find and recognize them. After the distances between the vehicle and the recognized landmarks were calculated by a visual distance measurement method, the location of the vehicle was computed according to triangulation finally. In this self-localization method, landmarks were encoded by interleaved 2 of 5, a type of 1-D barcode with high density. Each landmark has obvious visual feature and there is a unique corresponding location data to it in the landmark database. Distance between a landmark and the vehicle was calculated on the basis of the ratio of the coding area';s actual height to its height in the image according to the pinhole imaging principle. Experimental results showed that the self-localization method suggested almost meets the requirement for autonomous driving vehicle because of its high efficiency and precision.","PeriodicalId":35080,"journal":{"name":"农业机械学报","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86258043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
