Total trial area of 322.4 acres, received a total of 78,500 kilograms of seeds, the average yield of 243.6 kilograms, greatly exceeded the county over the years rice seed production per mu record. We use the time regulator mixture of 920 spray together, before and after a total of three spray. For the first time, when the mother flower flowering 30%, with flowers 150 ml plus nine twenty-five grams, with water spray 60 to 75 kg; the second time, when the female parent flowering 50%, with flowers 150 ml plus 9,203 grams, 60 to 75 kg of water spray; the third time, when the female parent flowering 70%, with flowers 200 ml, plus 9 2011 ~ 2 grams, with water 60 ~
