Effect Of Climate Change On Rice Production In Heilongjiang Province

Heilongjiang province is China’s high latitude and cold regions, is our country’s important commodity grain production base, the special geographic position and important role in the agricultural production of China, the academic circles pay close attention to the agricultural production changes became necessary topic. Studies have shown that changes in the production of rice, agricultural planting structure in Heilongjiang Province in the last hundred years. Indeed, Heilongjiang province paddy rice industry is a great change process.Based on the process of development of production of Heilongjiang province rice dialectic study, that the current status of rice production in Heilongjiang province is the interaction of various natural factors, social factors, technology factors, can also be regarded as the response of human behavior to natural conditions results.On the one hand, Heilongjiang province is Chinese highest latitude, climate is the most cold area, accumulated temperature is too low, lack of long-term growth season, restricting the agricultural production. View from the existing literature, before the end of the Qing Dynasty, Heilongjiang province is no plots of paddy rice planting. the rice production with the modern Korean immigrants into Heilongjiang province began, the earliest planting time of about eighty years of the nineteenth Century. After continuous development in the wave, from the beginning of twentieth Century eighty mid year, is entering a period of rapid development. In 2011 rice planting area has become one of the most important food crop in Heilongjiang province. This process of development and change, it is the past one hundred years rapid climate warming period, the climate warming is the most direct performance increased temperature, increased heat.On the other hand, the development of rice production in Heilongjiang Province, we pay close attention to "human" factors. It contains social factors, including science and technology, economic regulation, policy adjustment and cultural tradition of several major aspects. Firstly, the progress of science and technology through scientific breeding, cultivation techniques and the use of chemical fertilizers, herbicides, increase its rice production, quality, enlarge the rice planting area. From the introduction of it in breeding varieties developed into a plant varieties in their, variety characteristics selected by cold resistant, resistant to high quality, high yield changes. Cultivation technique in performance for the rice planting technology to Korean immigrants brought the gist based, constantly explore update rice cultivation techniques suitable for cold in Heilongjiang province. Especially in the later 80 years, the province wide promotion of upland rice cultivation technology system, making the yield and planting area of rice in Heilongjiang province have a leap in growth. At the same time, the use of chemical fertilizers, herbicides, also promote the expansion of increasing rice yield and sown area. Secondly, in the traditional culture, rice cultivation in Heilongjiang Province in modern times is a Korean immigrant, they not only bring the rice planting, also with the nation’s own traditional culture, it also influences the development of rice industry. Finally, rice production in Heilongjiang province is under the background of the change of economic regulation and policy adjustment under production policy.In summary, the rice in Heilongjiang province in the past one hundred years of rapid development is the interaction of various natural factors, technology factors, can also be regarded as the response of human behavior to natural conditions results. Now, Heilongjiang province is the production of rice area in China, its rice production is directly related to food security in china. Study of nearly a hundred years of rice production in Heilongjiang province in the change of "man and nature" of the interaction and relationship, not only related to the Heilongjiang province grain crop production, more related to the development of economy, national food security.Therefore, this paper aims to explore the area of Heilongjiang Province under the background of climate change over a long period of rice production and development of human society, and take on the natural condition change technology, technology reform, economic regulation, coping behavior, grasp the nearly hundred years of rice production in Heilongjiang province changes in the relationship between "man and nature", to tease out the various factors and the interaction of rice production. Hope for the cultivation of food crops in Heilongjiang Province Planning and production, to provide the theory basis of the suit one’s measures to local conditions to the government’s scientific decision-making.
