作物疯长大都是由于氮素施用过量造成的,而钾具有提高植物对氮素吸收利用的作用。据测定:凡处于疯长阶段的作物,植株体内以蛋白质为代表的氮化合物含量异常丰富,而氮化物丰富的部位,钾离子也十分活跃。这证明疯长作物并不缺钾,此时施钾肥容易使氮素的危害程度进一步提高,植株体内氮碳比失调加剧,而导致疯长势头升级。同时,氮化物含量的再度提高, Crops are mostly caused by excessive use of nitrogen, while potassium has the effect of increasing plant nitrogen absorption and utilization. It is determined: Where the stage in the madness of crops, plants in the protein-rich nitrogen content is extremely rich in the nitride-rich parts of the potassium ion is also very active. This proved that the crazy crops are not short of potassium, potassium fertilizer at this time is easy to make the harm of nitrogen to further increase the plant nitrogen and carbon imbalances exacerbated, leading to the momentum of soaring escalation. At the same time, the nitride content increased again,
