Key points for cultivation of a new super-high-yielding rice variety Taiyou 99

Taiyou 99 is the national rice leading species identified by the Ministry of Agriculture in 2010. Its advantages and characteristics are high yield, high resistance, high temperature resistance and excellent quality. The leaf shape is good, the tillering ability is medium and long, the growth period is longer, suitable for early sowing and early planting, and it is also sensitive to nitrogen fertilizer. The main cultivation points are as follows:

Early broadcast, thin broadcast, and cultivate more and more. Dilute and spread, cover the mulch and cultivate more sturdy. The age of 35 to 45 days, the number of tillers per plant reached 5 to 7.
