With 25-60 horsepower, 16m-30m sowing rate, compact structure, high performance, wide application, high efficiency, uniform broadcast sowing, etc.
配套动力25 ~ 60马力，播幅16 M - 30m。该机结构紧凑、性能优良、适用范围广、作业效率高、种肥撒播均匀等特点。
Sowing rate was then decided by integrating the effects of different soil water and salt contents, pH, temperature and sowing style on seedling emergence rate with relative weight method.
在此基础上，应用相对权重法计算土壤含水量、含盐量以及整地质量和播种方式等多个生态环境因子对出苗率的综合影响，进而确定播种量。
The experiment in the lab showed that the new device was effective in cleaning, low in broken rate of seed (less than 2%) and suitable for high-speed and accurate sowing.
经台架试验，清种效果良好，破碎率<2 % ，能够满足高速精播对清种装置的要求。
The low rate of sowing, wide space between rows, proper amount of nitrogen and phosphorous and a timely irrigation also had good effect on seed production of sainfoin.
低播量、宽行距、施适量的氮磷肥料、适时灌溉对红豆草种子生产亦有良好的效果。
And death rate of tiller and leaves existed difference in the year and next year, which increased as density of sowing increasing.
单株分蘖死亡率及单株叶片死亡率在播种当年及第二年存在差异，随密度增加而增加，但在播种第三年差异消失。
