Japonica rice is bred by Suihua Northern Rice cropping Comprehensive Research Institute. From 1997 to 1998, the average unit yield of 8311.0kg/hm2 in the regional trial was 8.0% higher than that of the control Dongnong 416, and the average unit yield of 7691.8kg/hm2 in the production test in 1999 was 9.1% higher than that of the control Dongnong 416. The number of childbearing days is 131days, and the active accumulated temperature is 2506.8 ℃. Plant height 89cm, panicle length 17.4cm, 101grains per panicle, 1000-grain weight 26g. Medium tillering ability, strong culm resistance, like fertilizer and water, cold tolerance at seedling stage. In 1998, seedling blast grade 8, leaf blast grade 3, ear neck blast grade 9, natural pathogen blast grade 9, leaf blast grade 3 and ear neck blast grade 7 were artificially inoculated. The quality of rice has reached the national first-and second-grade high-quality rice standards.

Cultivation techniques of Cotton stubble Wheat
In view of the late sowing date and low and unstable yield of wheat with cotton stubble, we explored a set of high-yield cultivation techniques for wheat with cotton stubble, which greatly increased the yield of wheat. In 1999, the planting area of the county was about 50,000 mu, with an average yield of 350 kg per mu. The main technical points are as follows: (1) pour enough soil moisture and apply enough fertilizer to make soil moisture before October 15, then pull out the cotton plant and transport it to the outside of the field, so that the late autumn peach will crack naturally on the cotton plant. Due to the large soil fertility consumption of cotton stubble, it is necessary to increase the amount of base fertilizer. But cotton stubble wheat sowed late, moved by the main stem and jointed.
