| Ulanqab is the largest area of potato cultivation in Inner Mongolia Autonomous Region.Potato is an important crop in the process of agricultural industrial structure adjustment in this region.Variety selection is the most important part of potato production,which directly affects yield,quality and planting benefit.In addition,potato cultivation and green pest control technology also indirectly affect the promotion benefits of new varieties.In view of the lack of regional promotion research of potato varieties,the water shortage in production,the aggravation of soil borne diseases year by year,and the difficulty in reducing the amount of pesticide application,this thesis is to explore the planting methods of Potato"Jizhangshu 12"according to local conditions and green ecology through the research of cultivation technology,demonstration,preliminary promotion research,promotion research of green pest control technology and benefit report analysis.The results are as follows:1.Jizhangshu 12 has the characteristics of good commodity and high yield in Ulanqab area;The best sowing date is from May 1 to 11;The optimum planting density is 4000plants per 667m2;The fertilization method is organic fertilizer（rotten sheep manure）with anti continuous cropping microecological granules（effective living bacteria≥500million per gram,solid granules）and 75%special compound fertilizer for potato（N-P2O5-K2O:12:19:16）.The application rates are used by 3000 kilogram,50 kilogram and 45 kilogram per 667m2;Considering the control effect of potato nevus in this area from the perspective of environmental protection and sustainable development,Trichoderma harzianum powder has application potential and value;Comprehensively considering the yield and commodity rate,the variety can achieve the best effect of high yield and quality by cutting off water and Fertilizer on August 27.2.Compared with the traditional popularized variety Kexin 1,the average yield increase rate of commercial potato of Jizhangshu 12 is 66.98%,which further verifies that the preliminary test is scientific and important,and has the popularization value and substitution value in Ulanqab area.3.The average yield per 667m2of Potato"Jizhangshu 12"in Ulanqab area is3114.72kg,which has the value of large-scale and long-term popularization compared with traditional varieties;Under the guidance of the production technical regulations for green prevention and control of potato diseases and pests,standardized production can drive farmers to plant the variety stably,which not only increases production and income,but also is conducive to the further long-term promotion of the variety.Through the popularization and application of Potato"Jizhangshu 12",the average yield of potato in this area is increased by 18.3%,the average new net income is 375 yuan per 667m2,and the total economic benefit is 315.421 million yuan.At the same time,due to the large-scale planting of new varieties,the utilization rate of water and fertilizer in cultivated land has been effectively improved;Through similar promotion research,we can also introduce other excellent varieties to better realize the local economic value,social value and ecological value of new varieties. |
