Hybrid rice is very adaptable. According to the six years of production practice in our region, either in the normal year, in the high-temperature year (1978) or in the low-temperature year (1980) as the late season rice or the double season late rice in the hilly polders, The performance can be substantially increased production, generally more than conventional late rice yield two or three jin per mu. The masses said: “hybrid rice is good, is the seed is hard to make.” Seed production of large workload, strong technical, process More, complex links, at a great price, and to a large extent affected by the climate
