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

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。

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；
