Cold damage of rice is one of the major disasters in rice production in Heilongjiang Province. According to statistics, since the founding of the country appeared once every 3-5 years, not only seriously affected the output of rice during that year, but also because of the decline of the quality of rice varieties, affecting future production. Since 1972, we started with the study of local laws of nature.
