桂北高寒山区采用抛秧技术的效应

The Effect of the Technology of Seedling Throwing in the High-Cold Mountain Region of Northern Guangxi

广西桂北高寒山区资源县采用抛秧技术的试验表明：旱育抛秧入土浅，分蘖从第一、二节长出，封行早，有效穗多，成穗率高，亩纯收入比旱育手插增收１９４４元，比水播手插增收２７２元，确是粮食增产增收的新技术。

Zi Yuan County is situated in the high-cold mountain region of Northern Guangxi,where the author applied the technology of seedling throwing.The experiment showed that the dried breeding throwing seedlings fell into the soil shallowly;the tillerings grew out from the first and second nodes of the rice plant;the rows of rice plants closed earlier;the effective ears of rice were more while the rate of survival ears was high.As a result,the net income of the rice increased 1944 Yuan/mu comparing that of dried breeding and seedling planting by hand;the net income increased 272.2 Yuan/mu comparing that of water breeding and hand planting.So,this method and technology was the new one for increasing grain output and income
