Study On Production Development And Industrialization Of Minor Crops In The Loess Plateau Of China

The Loess Plateau is one of the most important agriculture birth place in China with very long farming history. The climate in this region is typical continental arid, semi-arid and monsoon one with an average annual precipitation of 250-600mm. Since the rainfall is limited in amount, uneven in seasonal distribution, strongly changeable among years, and water and soil erosion is serious, drought has been the most serious nature disaster in the region, and often affects its agriculture sustainable developments. In a long period of time, planting drought-enduring crops is the intrinsic measure in rain fed area, so it's important ways for realizing agriculture and agro-economy sustainable development to select crops adapting to resources and circumstances, and to fully exploit crops'rainfall productive potential in rain fed area. Depending on their drought-resistant, poor soil-enduring features and stronger adaptability, the minor crops play a very important role in dry farming of the Loess Plateau from ancient times, and can't be lack up to now. And due to their higher nutrition and medicinal value, they are traditional raw material crops for health care foods in our country. Therefore, they are highly competitive in the markets at home and abroad, and contain huge economic benefits. Also, the minor crops are the main components in vegetation of the Loess Plateau and have important historic and practical significance for the water and soil erosion control in the region. So seizing the historical moment of strategic adjustment of agricultural structure in our country, conforming to the trend of market economy development, it will be the long-term strategic selection for agriculture of our country to develop the minor crops production in the light of local conditions, improve their productivity, and to realize characteristic agriculture industrialization. The main conclusions made in the research are as follows: 1.Considering the current situation of the development of the minor crops production, this paper makes it clear that improving productivity of the minor crops is the key and basic part of its high yield, high quality and high benefit production and its sustainable development, and shows clearly the research orientation of the minor crops nowadays. 2 It is pointed out that sustainable development of crops production is the important component of sustainable development of agriculture, and only the sustainable development of crops production is realized, can the foundation of the agriculture sustainable development be made. 3.The superiority of the production of the minor crops in Loess Plateau rain fed areas is analyzed, and it is regarded as "ecological crops"in this region for the function of environmental protection in some extent; also the paper provides the theoretical basis for developing minor crops production in the Loess Plateau rain fed areas after the systematic research about the minor crops production situation, area distributing and ecological adaptability. 4.Based on the analysis of the competitiveness of the minor crops, this paper reveals their better industrialization prospects. And it brings to light the main courses and restricting factors of the lag of the industrialization of the minor crops. The paper also puts forward the relevant strategies and countermeasures that will be very important to realize the characteristic agricultural industrialization of the minor crops in rain fed areas 5.It's the first time that the concept and connotation of the sustainable development of minor crops has been identified and the theory about intensive sustainable development for the minor crops production must be taken into the practical use at the present stage has been put forward in this paper. The research has creatively built up a technological system of obtaining the sustainable development of minor crops, which is embodied from the sustainable improving use efficiency of rainfall resource, emphasizing protective cultivation , paying attention to produce the green product ,and constantly improving the economical benefits of the minor crops and decreasing environmental side effects in maximum limit as well. And also some countermeasures for the necessary protection of the system is put forward.
