水稻施氮指标体系

STUDY ON INDEX SYSTEM OF PADDY-FIELD FERTILIZER APPLICATION

该项研究依据叶龄进程,对水稻群体和土壤氮素进行测定,在获取大量数据的基础上,应用微型计算机组建水稻各生育期施肥指标技术体系,该体系通过农场小区和百亩方多点试验,证明增产增收效果显著,方法简便易行,有推广使用价值。

Based on the courese of leaf age, we analysed the nitrogen contents in rice plants and soil and computerized plenty of data gained from assays of plant and soil, then we established the index system of fertilizer application at different growth stages of paddy. The experiments on index system of fertilizer application in small area and 100 mu in two state farms showed that the paddy yield was obviously increased. The method is feasible and easily learned in practice and so worthy to be popularized.
