High-yielding cultivation techniques of Rice "Hybrid glutinous intercropping"
Rice "hybrid glutinous interplanting" refers to the intercropping and cultivation of hybrid rice and glutinous rice. That is, medium-culm hybrid rice and high-culm glutinous rice, making use of the wide row advantage of hybrid rice in wide and narrow rows, increase the planting mode of single-row glutinous rice according to a certain band width, row ratio and width. 1. The main advantages of hybrid waxy intercropping technology 1. Increase rice yield: the results showed that the total yield of hybrid waxy intercropping was 28 kg higher than that of ordinary hybrid rice per 667 square meters and 110 kg higher than that of conventional glutinous rice. 2. Increase income: glutinous rice ratio

Breakthrough in Japonica Hybrid Rice breeding
The reporter learned from the Shanghai Academy of Agricultural Sciences on the 18th that Shanghai agricultural scientists have made a breakthrough in the breeding of japonica hybrid rice in the Yangtze River Basin. After obtaining the first restorer line of hybrid late japonica rice in the Yangtze River basin which was granted the right of national protection of new plant varieties, the first southern hybrid late japonica rice combination approved by the national variety was bred. At present, a series of strong dominant combinations have become an important support for the "provenance" of japonica hybrid rice in the Yangtze River Basin. Researchers of the crop breeding Institute of Shanghai Academy of Agricultural Sciences used the intermediate materials of indica and japonica subspecies as "bridge parents".
