Technical Summary of Rice Yield Exceeding 10 Tons per Hectare for Three Consecutive Years

摘要

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 largescale demonstration,it was known that the high-yielding varieties and high-yielding cultivation methods should be promoted at the same time.In the cultivation process,it was recommended to take reliable,effective,and simple and feasible technical procedures.
