    A pot experiment was carried out with tobacco (N.tobacum) grown on Nanxiong Purplish soils and Laterjtic red soil as a contrast in 1984. The changes of soil K and absorption of K by the plant during the course of tobacco growth were determined, and the yield and quality of tobacco were measured. Complementary field investigations were also conducted. Experimental results indicated:The contents of various forms of K in Nanxiong Purplish soils were medium to high. The release of K by weathering of minerals was...

    A pot experiment was carried out with tobacco (N.tobacum) grown on Nanxiong Purplish soils and Laterjtic red soil as a contrast in 1984. The changes of soil K and absorption of K by the plant during the course of tobacco growth were determined, and the yield and quality of tobacco were measured. Complementary field investigations were also conducted. Experimental results indicated:The contents of various forms of K in Nanxiong Purplish soils were medium to high. The release of K by weathering of minerals was relatively quick, and the capabilities of K Supply and preservation in the soils were comparatively strong. Non-exchangeable K was an important sourse of the K nutrition of tobacco, therefore it should be taken as an important index for evaluating the roils in tobacco-plentirg district. The percentage of K contained in tobacco plant was the highest in the period of rapid growth, and the amounts of K absorbed by the plant in various periods were in decreasing order, harvest period, rapid growth period and early growth period. Both were enhanced by the rsjse of the level of K fertilization. For the Purplish soils high jn K,K fertilizing had no significant influence on tobacco yield, but benefied the improvement of tobacco quality; for the one medium in K, it had beneficial influences on tobacco yield and quality. The effect of low level of K fertilization was a bit better. K fertilizing to Lateritic red soil could improve tobacco yield and quality significantly and made the symptoms of K deficiency disappear, and the effect of higher level of K fertilization was more significant. The proper time for K fertilizing was the early part of rapid growth period.

    本文研究广东省南雄紫色土含钾量、钾素供应和烟草吸钾的特性及其对烟草的产量和品质的影响,并以花岗岩形成的赤红壤作比较。于1984年进行盆栽试验,且辅以化学分析和适当的田间调查。试验结果表明:南雄紫色土含钾量属中等至丰富水平,矿物风化释钾较迅速。供钾和保钾能力较强。烟草吸收缓效钾量约占其吸钾量的1/3至1/2,缓效钾是烟草钾素营养的重要给源,应作为烟区土壤评价的一个重要指标。烟草植株含钾率在旺长期最高,而吸钾量则是成熟期>旺长期>伸根期,两者均随着施钾水平提高而增加。不施钾时,南雄紫色土的烟草产、质比赤红壤高;含钾丰富的紫色土施钾肥对烟草产量无明显影响,但利于烟草品质提高;含钾中等的紫色土施钾对提高烟草产、质有利。施少量钾肥的效果较好。施钾肥于赤红壤,可明显提高烟草产、质,施多量钾肥效果更佳。施钾肥宜在烟草的旺长初期。

    The selection of participating factors and the determination of gradation indices are essential to soil evaluation. The evaluation factors should be selected respectively in accordance with the following G utilization types, dry land, paddy field, vegetable garden, orchard, forest land and range land. The main limitiing factors should be selected, that are important effect to the growth/development, and the productivity of the -utilization type or the crop combination, and are highly stable, in accordance with the soil characteristics and environmental conditions.Quantitative indices should be used in the gradation of the participating factors.Critical biological indices should be used as much as possible for the main grades. A participating factor may vary with region and utilizationtype.This paper describes the selected participating factors, that are suitable to the G utilization types nationally, and the gradation indices that divide the participating factors into 4 grades and 5 classes.

    参评因素的选定与分级指标的划分是土壤评价的核心工作.参评因素应按旱地、水田、菜地、园地、林地及牧地六种利用类型分别选定.应选取对该利用类型或作物组合的生长发育和生产力具有重大影响的、稳定性较高的主导限制因素,并以土壤属性为主,结合环境条件因地制宜选定.参评因素的分级指标应尽量采用定量指标,为分等定级提出定量依据,其主要级差应尽量利用有生物学意义的临界指标.同一参评因素在不同地区、不同利用类型上有所不同.在目前全国无统一规定条件下,本文选定了适用于全国六种利用类型下的参评因素及划分为四等五级的分级指标.

    Through gradual regression analysis to ten kinds nutritions of soils of 54 counties, Saanxi province, the optimum regression model for soil nutritions (including alkaline—N, quick action P; quicick ackaction K, B and Zn) has been set up. It shows that soil fertility is the limit factor of wheat production in Guanzhong plain, but this is not ase in North Shaanxi loess plateau gully hill region. Finally, correlation analysis and fuzzy cluster on soil nutriments have been done.From above mentioned, we can get a...
