A Study on the Establishment Technique of Direct Seeding Rice under the Zero Tillage Condition

水稻免耕直播全苗技术研究

The gain via 2 cycles of recurrent selection for ASI ( anthesis-silking interval) in two maize populations was investigated under conditions with or without plastic cover and direct seeding or transplanting.

利用两个群体各二个轮回选择周期的材料，研究了ASI（散粉至抽丝间隔）在盖膜与露地以及直播与移栽条件下的反应。

The test proved that, the seeding quantity variance coefficient of the allotter with the shunting cone is lower by 2% than that of the allotter without the shunting cone under the same work conditions.

试验结果表明：如果其它条件不变，分配器安装分流圆锥要比不安装分流圆锥时的变异系数低2%左右；

Under normal temperature, the UWL intensity of seeding leaves was increased with the rise of culture time.

常温下，大白菜幼苗的UWL强度随着培养时间的延长而呈上升趋势。
