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
本課題針對2bps - 2型坐水鋪膜播種機坐水后,土壤水分蒸發損失大和機組作業速度低的突出問題,通過對水在土壤中運動的理論分析,提出了在行間膜下的暗道式施水方案,圍繞此方案設計了三種坐水部件,並就不同坐水部件在不同施水位置施水后,種子帶土壤含水量的變化進行了試驗研究。
