Jiangsu bred Japonica Rice with Disease and insect Resistance
A breakthrough was made in the breeding of new japonica rice varieties with multi-resistance, high yield and high quality in cooperation between Bokun Agricultural Research Institute of Yixing City, Jiangsu Province and China Rice Research Institute. 4701, 4714 and other new high-yield and high-quality japonica rice lines resistant to brown planthopper, rice blast and other diseases and insect pests were successfully bred.
It is reported that the new japonica rice lines with high yield and high quality aggregated the genes of resistance to brown planthopper, white-backed planthopper, rice blast and stripe blight, as well as high yield and high quality specific genes.

Vigorously popularizing the return of rice straw to the field is one of the most economical and effective ways for the recycling of nutrients from soil-crop-soil. It plays a very important role not only in improving soil and improving soil fertility, but also in improving soil potassium and silicon nutrition conditions, balancing crop nutrition, and alleviating the contradiction between the shortage of potash fertilizer resources and the rapid increase in chemical fertilizer prices in China. 1. Increase the content of soil organic matter, the content of organic matter in rice straw is high, and the content of organic matter in dry rice straw is 40%, which is beneficial to soil organic matter after returning to the field.
