In this paper, sowing date, variety selection , breeding methods , planting density , fertilization , pruning and disease control , etc., of the summer -season tomato cultivation efficiency of the section of the key technologies , and conduct demonstration, research results are as follows : Through the investigation research areas in Guiyang choose an altitude of 800 meters above the place April 15 to May 15 planting, arrange the listing period August to October , with a price advantage in the target market , the selling price is high and stable . Stone 308 steel , steel stone 138 , Experian other high-end tomato varieties , good quality, good storage , long shelf life , in line with market demand, Guangdong and Guangxi and other targets , by traders alike. Fixed pitch swing through sowing , use of local wild rootstock grafted tomato seedlings , seeds can not only significant cost savings , but also increase production. Using self- fertilization can reduce costs and improve productivity. Control planting density, according to 70 cm × 40 ~ 50 cm row spacing colonization , Guiyang summer rainy season is cultivated tomato and obtain efficient critical success , which will help air and light and pest control , but also can save seeds, frame materials , pesticides , etc. costs. In the field management of a single pole pruning and thinning management, can significantly improve the yield and fruit products . In order to combat late blight on pest control and anti- mainly other worms, choose a new manganese raw , fierce killing, Dimethomorph low toxicity and efficient chemical control of late blight and other relatively low-cost and effective. Through a lot of trial data research and demonstration application that uses the supporting technical measures can make summer -season tomato cultivation to achieve efficiency of the section results.
