| Potato is a traditional dominant crop in Jingbian,northern Shaanxi,with a planting area of 400,000 mu.The potato industry has become the backbone of modern agricultural construction in Jingbian.However,due to continuous planting for many years,the production technology lags behind,causing a lot of problems,such as the disorder of potato varieties,frequent disease,decreased yield and poor quality,which affects the development of Jingbian potato industry and market.Therefore,how to use reasonable planting methods and management modes to improve potato yield and quality in actual production has become very important,and how to promote the development of Jingbian potato industry through marketing is also particularly critical.Based on the technical basis of agricultural cultivation in drylands,this study conducted in-depth field production surveys and consulted literature to summarize existing problems.Experiments on the effects of different irrigation methods on potato yield,the effect of row spacing and storage conditions on potato quality were carried out.Methods to improve potato yield and quality were obtained.The advantages and disadvantages of the potato market were analyzed from different perspectives,and Jingbian potato marketing strategies were formulated in terms of product pricing,channels,and promotion strategies.The main results are as follows:(1)Through reviewing the literature and field survey,the current potato production quality and market development status were generalized,and the current status and existing problems of potato production in Jingbian were summarized.The main problems are: disordered varieties and single structure;serious disease,lower yield and quality;low penetration rate of virus-free seed potatoes;and slow market development.This will provide basic data for the research of potato yield quality improvement technology and marketing.(2)By designing the different experiments,the relationship between potato irrigation methods and yield was studied.The effects of different drip irrigation treatments,drip irrigation under film and different irrigation methods on soil water content,water use efficiency,growth and development,yield and economic traits were discussed.Analysis of the changes in various indicators showed that the use of drip irrigation under the film and drip irrigation on the ridge can increase the soil water content and water use efficiency,the potato grew well,and the yield and economic properties were significantly better than other irrigation methods.It showed that drip irrigation is the most suitable irrigation method for potato cultivation in Jingbian and can increase potato yield.(3)The experiment explored the effect of different plant spacing ratios and storage methods on potato quality,and measured and analyzed the changes of potato starch content,vitamin C,respiratory intensity and reducing sugar content under different experimental conditions.As a result,it was found that the potato planting quality was better when the plant-to-row ratio was 1: 2.Under the temperature-controlled storage conditions of 4 ℃,the content of starch and reducing sugar in potato tubers was relatively stable,the content of vitamin C decreased slowly,and the respiratory intensity was significantly reduced,which better extended the storage time of potato tubers,thereby improving potato quality.(4)The SWOT of the potato market in Jingbian was analyzed and summarized by consulting the data and research.Aiming at the problems existing in the industrial market,a potato marketing strategy suitable for Jingbian was formulated from the aspects of product pricing,marketing channels,and promotion strategies.It further explained that the development of the industrial market must be based on a standardized market system and scientific management system.In summary,despite the rapid development of the potato industry in Jingbian,there are still many problems.While increasing potato output and quality,reducing costs,implementing marketing strategies,expanding marketing channels,improving the industrial market system,and increasing the popularity of potato products can make the development of the potato industry have broader prospects. |
