种子带 meaning in Chinese
seed tapes
Examples
- The examination method of seed with rust and leaf spot of sugar beet
甜菜种子带锈病和褐斑病菌检测方法的研究 - Based on the design methods above , we research the possibilities of build nonuniform filter banks with linear phase in the third part , pointing out the difficulties may occur and bringing up our ideas
第三部分，我们在上述两种子带滤波器组设计方法的基础上，探讨了构造非均匀的线性相位滤波器组的可能性，指出了存在的困难，提出了构造的设想。 - In order to overcome the disadvantage of 2bps - 2 plastic film mulch seeder with watering apparatus that the operation speed is limited and the moisture evaporation loss is great , according to the theoretic analysis of water movement in soil , this paper offers another watering project - hidden watering under film , designs three different types of watering devices , meanwhile conducts test research with different watering devices in different position the change of the soil moisture content
本课题针对2bps - 2型坐水铺膜播种机坐水后，土壤水分蒸发损失大和机组作业速度低的突出问题，通过对水在土壤中运动的理论分析，提出了在行间膜下的暗道式施水方案，围绕此方案设计了三种坐水部件，并就不同坐水部件在不同施水位置施水后，种子带土壤含水量的变化进行了试验研究。 - On the basis of all these , the paper researches that the soil moisture content reduces slowly after 7 days ， so establishes a main criterion of evaluating watering feature - the increment of average soil water content in 7 15 days . according to these theories , we draw an conclusion - water is injected at the position away from seed zone 3 . 5 ( cm ) , 6 ( cm ) deep with vertical flat nozzle , the effect of watering is better at the operation speed of 0 . 9m / s
得出7天后土壤含水量呈缓慢变化的趋势，进而提出了以7 15天平均土壤含水量与初始含水量的差值作为评价坐水性能的指标，以此为依据得出在机组作业速度由0 . 5m / s增加到0 . 9m / s的情况下，采用竖扁（不带翅）施水管将所需的水施到种子带横断面内3 . 5cm ，深6cm的位置，坐水效果较为理想。
