The results showed that plant height increasing speed was significantly slow at the former and middle stage when K level was above 180 kg/hm2.On the contrary,the height of case-hardened plant improved markedly.When the K level was above 135 kg/hm2,the stem girth and maximal leaf area differed significantly as compared with CK,so did LAI.Yield and product value per unit area took the first place when 180 kg/hm2 potassium was used.Average price and proportion of middle and first grade tobacco leaf of 225 kg/hm2 potassium treatment were the highest as compared with other treatments and CK.Four economic characters of the two treatments differed at obvious significant level as companied with CK.The total sugar and K2O were increased,nicotine, total N,protein and Cl- were decreased with increased K levels.The potassium lacked symptom was alleviated with increased K levels,no symptoms was observed when 180 kg/hm2 potassium was used,the degree of weather infected fleck was decreased when the K levels was increased.
结果表明,在烟株生长前中期,当施钾量达到180 kg/hm2以上时,株高增长显著变慢,而定型株高则显著增高;茎围和最大叶的面积在施用135 kg/hm2以上的处理与CK之间的差异性达到极显著水平,叶面积指数也存在显著差异;单位面积产量和产值以施用180 kg/hm2的处理居首位,中上等烟比例和均价以施用225kg/hm2的处理最高,这两种处理的以上4个经济性状与CK之间存在极显著性差异;烟叶中的总糖和K2O含量随施钾量的增加而上升,烟碱、总氮、蛋白质和C-含量则下降;缺钾症状随施钾量增加而减轻,至施用180kg/hm2时已无缺钾症状;烟叶气候斑的发生程度也随施钾水平的提高而减轻。

The results show that under crop rotation of wheat and maize in damp soil and brown soil, stalks return to fields integrated with applying potash fertilizer can keep K balance within a cycle and K return rate reaches 109.1%~111.9%, annual wheat stalks return to fields can provide 226.5~261.0 kg/hm2 K, meanwhile the K return rate reaches 95.2%~97.1% for only applying potash fertilizer; under crop rotation of wheat and soy bean in grittiness black earth, only applying potash fertilizer can also keep K balance within a cycle, its K return rate reaches 119.9%, meanwhile the K return rate reaches 142.0% for stalks return to fields integrated with applying potash fertilizer, which result from maize being much more absorption to K than soy bean.
在砂姜黑土区小麦+大豆轮作制度下,即使小麦秸秆不还田,仅施用化学钾肥,亦能维持小麦-大豆轮作周期钾素的平衡。施钾配合秸秆还田处理,钾归还率达142.0%,施钾且秸秆不还田处理钾归还率达119.9%。主要是大豆不象玉米那样带走较多的钾造成的。

Research results of phase equilibrium for the KOH—K〓CrO〓—H〓O system, the KOH—KAlO〓—H〓O system and the KOH—K〓CrO〓—KAlO〓—H〓O system revealed that lower concentration of KOH was beneficial for the crystallization of KAlO〓, and within a certain range, higher concentration of KOH was favorable for the crystallization of K〓CrO〓.
KOH—K〓CrO〓—H〓O体系,KOH—KAlO〓—H〓O体系和KOH—K〓CrO〓—KAlO〓—H〓O体系相平衡研究结果表明,较低的氢氧化钾浓度有利于铝酸钾结晶析出,一定范围内,较高的氢氧化钾浓度有利于铬酸钾结晶析出,因此,通过控制氢氧化钾浓度可以使铬酸钾—铝酸钾—氢氧化钾得以分离。
