植物通过根系吸收养分,通过渗透和质流输送养分,一般认为土壤水势在—0.1～—10巴的范围内,有利于促进养分的利用。田间作物的生长,通常受着从饱合态到严重亏缺这一范围内水分的波动所制约。在印度古吉拉特某些地区,由于自然降雨不够稳定,在花生生育期内存在着不同程度的缺水现象,为此进行了试验以了解不同土壤水势梯度下花生养分和积累及其吸收利用率。 Plants absorb nutrients through the roots and transport nutrients through osmosis and mass flow. It is generally accepted that the soil water potential is in the range of -0.1 to -10 bar, which helps to promote the utilization of nutrients. The growth of field crops is usually governed by fluctuations in moisture within the range of fullness to severe deficit. In some areas of Gujarat, India, due to the lack of stability of natural rainfall, there are some water deficits during the growth period of peanut. Experiments were conducted to understand the nutrient accumulation and absorption of peanuts under different soil water potential gradients rate.
