到目前为止,水稻施用钾肥增产已报道不少,但在增强抗逆性能方面的则不多见。我们在水稻上施用钾肥有较好的增产效果已为连续三年来的试验所证实。本文则在此基础上进一步研究钾肥对增强水稻抗逆性能的作用。 So far, there have been a lot of reports on the increase of paddy yield in paddy fields, but few in terms of enhancing the resistance to stress. Our better yield-increasing effect of applying potash on paddy has been confirmed by experiments conducted over the last three years. Based on this, we further study the effect of potash fertilizer on enhancing the resistance of rice.
