This study was carried out with aiming of developing on paddy rice management technology for high quality grain yield using the spectral reflectance of paddy rice leaves during cultivationg period. Test sites were selected farmer's fields on Satsuma-town at the northern part of Kagoshima Prefecture. Climatic conditions, i.e. solar irradiance, temperatures of near leaves and soil in each paddy ricefield, were measured and recorded. Heights and number of stems the spectral reflectance were examined and measured on each point in each paddy rice field. It was certained that the wavelengths, 660nm and 770nm, were represented the chlorophyll content of paddy reice leaves. The new instrument, used the bandpass filters i.e., 660nm and 770nm, was test-manufactured. The data of fertilizers in paddy-rice cultivation and the yields and grades of carnel on each field were repoeted by each farmer.This study clarified as follows. (1) Height, number of stems and leaf area index (LAI) were not regardless with carnel grade. (2) As the temperature of near leaves on each grwoing stsge were differed on each field, it was suggested that the temperature was affected with carnel grade. (3) The variation of soil temperature in first-grade field was smaller than that of other grade. (4) After the heading stage, SPAD values were differed with grade field. (5) As the values of index, ND_<770,660>=(R_<770>-R_<660>)/(R_<770>+R_<660>), showed the high correlation with SPAD values, pseudo image, ND_<770,660> image, adapted this index, showed the possibility of the clarity the grade fields. (6) The variation of the brightness in this pseudo image, calculated with histogram of this image, showed the result that low variation was at the first-degree carnel grade.These results showed that the spectral reflectance of paddy rice leaves during cultivationg period was effective for the developing on paddy rice management technology for high quality grain yield.

本研究旨在利用水稻栽培期叶片的光谱反射率，开发水稻优质高产管理技术。试验地点选择在鹿儿岛县北方萨摩镇的农民的田地。在每片稻田中，测量并记录了气候条件，即太阳辐照度、近叶温度和土壤温度。在每片稻田的每个点上对水稻的高度和茎数进行了光谱反射率的检查和测量。确定了660 nm和770 nm波长代表水稻叶片叶绿素含量。新仪器使用带通滤波器，即，660 nm和770 nm的两种波长的荧光粉进行了试制。本研究以各农户为单位，分别报告了水稻栽培中的肥料使用情况、各田的产量及产量等级。(1)株高、茎数、叶面积指数与品种等级无关。(2)由于各生育期近叶温度在各地块上的差异，说明温度受山茱萸等级的影响。(3)一级田土壤温度的变化幅度小于其他等级田。(4)抽穗期后，SPAD值随田块的不同而不同。(5)ND_（770，660）=（R_<770>-R_<660>）/（R_<770>+R_<660>）与SPAD值有很好的相关性，伪像、ND_（770，660）图像采用该指标，显示了等级场清晰的可能性。(6)利用该图像的直方图计算了该伪图像的亮度变化，结果表明，该伪图像的亮度变化在一级灰度范围内变化很小，说明水稻叶片光谱反射率在水稻栽培期间的变化对水稻优质高产管理技术的研究是有效的。
