In recent years, the planting area of early rice in Zhejiang Province has dropped while the grain price has risen sharply. The people’s demand for planting high-yielding varieties has become increasingly stronger. Zhejiang Province, southern Zhejiang, early hybrid rice cultivation has tasted the sweetness of high yield, planted a high yield level. In 1994, the hybrid early rice in southern Zhejiang and Zhejiang provinces showed outstanding performance, giving full play to the advantages of large grains and spikes, and the average yield per mu was 50 kilograms or more than that of conventional early rice. At present, seeds are being prepared all over the country. In 1995, there will be a large area for promotion and a good prospect for development. First, the characteristics of early hybrid rice 1. High yield According to the 1993-1994 two provinces test results, early hybrid rice test group
