Super High-yielding Cultivation Techniques of Super Hybrid Rice Yongyou 12

Super hybrid rice Yongyou 12 has the characteristics of the longest growth period, stouter stem, less heading per unit area, bigger panicle, more grain per panicle, etc. Compared to the conventional varieties, Yongyou 12 always has high yield and shows super high yield potential in practice. With the understanding of the variety's characteristics, the fields with yield over 13.5 t/hm2are increasing year by year. According to the experiences, super high-yielding cultivation techniques were formed to get the yield over 13.5 t/hm2: optimum sowing period, less seedling rate and cluster, more organic fertilizer, more ditches in field, more panicle fertilizer, controlling rice false smut, avoiding premature senility, avoiding premature water break and cut green.
