soil water diffusion rate 土壤水分扩散率
The methane emission from soil to the atmosphere is mostly through rice plants, only small amounts of methane is released across the water-air interface via bobbles or molecular diffusion.
后者主要是通过水稻植株向大气释放，只有少量通过气泡或分子扩散从水田土壤通过田面水层向大气排放。
It contains nutritious elements and rich water, and has high diffusion resistance in soil of retaining in the applied position reaching the delay-releasing effect.
含有营养元素的富水液体在土壤中的扩散阻力陡增，长时滞留于追施部位，达到了液体肥料缓释的效果。
