张罡摘要： 1万t防结块工业硝酸钾的生产装置选用硝酸镁与氯化钾为原料，采用新研究开发的复分解循环反应法生产硝酸钾新工艺，副产品为六水氯化镁，六水氯化镁含少量硝酸钾，故称之为氮钾镁肥。

Corn seedling were grown for 5 harvests in pot experiments to evaluate potassium supplycapacity of the soils.Results indicated that when soil avaliable potassium decreased,the dryplant matter was firstly affected,secondly was the total uptake of potassium by plant,then was thepotassium content in plant.Exchangeable,nonexchangeable and mineral potassium wereavaliable for plant,but the contribution of each potassium form was depended on soil types.

本文在研究褐土、潮土不同层次土壤的供钾特性、土壤各形态钾素的动力学行为以及小麦根系对钾素的吸收动力学特征的基础上，以玉米幼苗从土壤中的吸钾量为对照，考察了土壤钾素动力学特征与土壤钾素生物有效性的关系，运用热力动力学理论建立了土—根系统中的钾素能态链，并确立了土壤钾素生物有效性的能态指标。

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。

Of the potassium chloride products is directly used as the fertilizer, while the rest as the raw materials to produce caustic potash, potassium sulfate, potassium nitrate and potassium phosphate.

氯化钾产品85%直接用作肥料，其余部分作为生产苛性钾、硫酸钾、硝酸钾和磷酸钾的原料。

Currently, we are Chinese and potassium sorbate, potassium citrate and potassium phosphate, potassium chloride, one of the major producers.

目前，我们是中国山梨酸钾，柠檬酸钾和磷酸钾，氯化钾的主要生产商之一。

The investigated potassium carboxylates included: monocarboxylate potassium acetate, dicarboxylate potassium tartrate (K2Tart), tricarboxylate potassium citrate (K3Cit), and tetracarboxylate dipotassium of ethylenediaminetetraacetic acid (K2EDTA). KOAc can only induce calcium oxalate monohydrate, while K3Cit and K2EDTA induce COM and calcium oxalate dihydrate. The ability of multicarboxylates to induce COD formation was increased with increasing their concentrations.

加入一元醋酸钾只生成一水草酸钙晶体；三元柠檬酸钾(K3Cit)和四元乙二胺四乙酸二钾(K2EDTA)可诱导二水草酸钙形成，且随着其浓度增加，对COD的诱导能力增加，而二元酒石酸钾(K2Tart)同时诱导了COM， COD和三水草酸钙生成。

Eighty percent of the potassium taken up by cotton was from nonexchangeable potassium of the soil.Both the pot and the field experiment showed a same result that the content of soil nonexchangeable potassium will no longer decrease when it reached a certain level,while nonextractable potassium with 1 mol/L HNO3 will continue to decline.

棉花吸收的钾素中有80%来自于土壤非交换性钾，盆栽生物耗竭与连续种植10年棉花的田间土壤，具有相同的结果，土壤交换性钾在下降到一定程度后不再下降，而1mol/LHNO3不能提取的钾一直在下降。
