A Study Of The Planting Technology On Special Economic Crops

Production practice and research results show that the influence of different promotional modes on agricultural production is significantly different.The production of Chinese medicinal plants and the grain crops has the same characteristics as the common.Huang Jiang(Dioscorea zingiberensis C.H.Wright)is one of the most important medicinal plants in China,and Shaanxi is the largest province in the country's Huang Jiang planting.This paper focuses on the influence of different varieties on the development of Huang Jiang industry,and provides a reference basis for the promotion of Chinese medicinal herbs.In this paper,a summary of author's own scientific research information,Shaanxi Huang Jiang industry technology innovation strategic alliance,the author from Huang Jiang planting and the research data of the first processing enterprises,such as the foundation,the growth area of Yellow Ginger,the yield of yellow ginger root and the purity of the yellow ginger varieties were expected target,the effects of several popularization modes on Huang Jiang varieties were studied by statistical analysis.In this paper,the promotion model of the Yellow Ginger varieties is summarized into five types by the extension of the main subject and the production method.Namely: the quality of the conservative promotion mode;technology demonstration promotion mode;market-oriented marketing mode,industry consistent promotion mode and stochastic development model.The research and teaching unit of quality-based promotion model is based on research and research as the main subject,focusing on the purity and quality of the varieties;The technology based promotion model is dominated by the government.In order to ensure the continuous development of the industry,it is often given the policy support,the protection of price compensation during the downturn of the market;equipped with management and technical cadres for technical guidance;Market-oriented promotion mode is subject to small enterprises.Enterprises are greatly influenced by the market,but small enterprises are thin,lack of long-term planning,not getting government funds to support them,change to the market as fast as possible when saponin prices are high,planting enterprises hoards raw materials to capture the market;otherwise,they grows other Chinese medicine,and the processing enterprises change to extrac the effective ingredients of other Chinese herbal medicine with the process of using the equipment.Therefore,small enterprises generally do not do the technical research and the good kind of purification,the area and quality of the Yellow Ginger varieties are difficult to ensure;The industrial persistence model is subject to the professional cooperatives.Huang Jiang industry cooperatives in order to ensure their own enterprise reputation,and the enterprise has established the interest relationship which is based on the trust,according to the technical means and the management system,the production of dioscorea saponins was high and stable.Dioscorea saponin processing enterprises and professional cooperative cooperation,greatly reduced the product's laboratory samples,the stability of the supply chain is guaranteed,and the risk of market volatility and the quality of product is avoided;The model of random development model is a spontaneous promotion of Huang Jiang-grown professional households.Professional famers without their own special breeding land,they interchange varieties of each other,buy,one-time gain,in conjunction with the use of the year,generally do not make pure,the variety of multi-generation non-sexual reproduction not only quality decline,and the increase of the rate of strain is rising.In five promotional modes,the variety of purity has been established by scientific research and teaching unit,which is the highest level of research-type plant resources and original breeding base,the varieties do not mixed;secondly,the technical model-based breeding base for the good breeding base of professional cooperatives and the establishment of the government,these two types of model have the technical guarantee,the purity is higher;the main guide type and the immediate development model of the market are completely affected by the market,the trend is moving,the purity is low,especially the latter,the purity is not guaranteed.The saponin content of the model one,the mode two and mode four are very close and the character of the original species is maintained,single production is also higher than the other two modes.Model one is the technical personnel direct operation,the mode Er He mode four have technical personnel as the technical support,the Mode San He mode five does not have technical personnel participation,the difference is obvious.Again,in the process of the promotion of Yellow Ginger,the participation of the technical personnel is the key to the quality of the production quality of the Yellow Ginger varieties.In summary,the research-based promotion model has the best effect on maintaining the purity of varieties,and the promotion model supported by technicians is conducive to the improvement of the content of diosgenin and the average yield per unit,and the two models mainly composed of government and professional cooperatives are favorable to The area for promotion has been expanded,and scientific research units,professional cooperatives and the government are most important in promoting the cultivation of special economic crops.It is recommended to construct a multi-cooperative model system that complements each other's advantages,and to further give play to the promotion role of new-type business entities.
