Abstract
In Heilongjiang Province, rice planting area increased year by year. However, due to improper cultivation methods, farmers did not have knowledge about characteristics of rice varieties, there was still no complete cultivation technology system. The yield of different regions varied widely. The increase in rice yield was relatively low, and yield per hectare remained at 7 tons. Through the recent three years of large-scale demonstration, it is known that at the same time of promoting high-yield rice varieties, it is recommended to promote high-yield cultivation method. In the cultivation process, it is recommended to take reliable, effective, and simple and feasible technical procedures.
