Soil application of EDTA·Na2Fe significantly reduced the Cd accumulation in rice roots, shoots and rice grain.
      
Cd concentration in white rice of both rice genotypes in the treatment of soil application of EDTA·Na2Fe was much lower than 0.2 mg/kg, the maximal Cd permission concentration in cereal crop foods in State standard.
      
However, soil application of FeSO4 or foliar application of FeSO4 or EDTA·Na2Fe resulted in the significant increase of Cd accumulation in rice plants including rice grain compared with the control.
      
It may be a new promising way to regulate Cd accumulation in rice grain in rice production through soil application of EDTA·Na2Fe fertilizers to maintain higher content of available iron and ferrous iron in soils.

In regions of the major litchi production area, problems usually arised when flowers of litchi fruit trees at bearing ages(about 15-20 years old) failed to fruit. and conditions such as abscissions of flowers and fruits with unstable or low yields occurred. It was speculated that boron stress may be the cause of failures in pollination or fertilization leading to the decrease of unit area fruit production. Borax in different concentrations together with potassium dihydrogen phosphate gave good results in promoting leaf contents of boron, nitrogen, and chlorophylls so as to increase fruit yields of healthy bearing litchi trees. Three treatments were eminent in the experiments, namely, B 0.2%~0.4% spray. B 0.2%+KH_2PO_40.2% spray, and B 4-5 liang/tree soil dressing. At the concentration range of 60 ppm. this microelement advanced the germination as well as the growth of pollen tubes. Thus created very favorable conditions for fertilization and greatly increased the fruit setting rates. However, concentrations of borax adove·80 ppm showed inhibitive effects.

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。
