水稻幼穗分化期氮肥需要性診斷試驗

廖上池

摘  要

本試驗目的在試探於幼穗形成期用Asparagine酸層析診斷法作為穗肥要否之準繩。在59,60兩年計4期作,4品種及三種處理來作試驗結果雖尚未達到最後結論,但已可提供許多可資參考有價值的代表性基本資料諸如在各期作各品種的收量曲線葉片顏色變化層析技術及碘反應等。


Diagnostic techniques for Detecting Need at Panicle Initiation Age on 3 Japonica Rice Varieties and One Indica Rice

S. C. Liao

Summary

       The objective of this program is to test the reliability of chromatographic technique of asparagines detection in diagnosing the need of rice plant for additional nitrogen dressing at the panicle initiation stage.

       We have not yet reach a successful goal on this experiment from 2 years program (1970~1971) 4 crops, 4 varieties (Tainan 5, Taichung 186, Nankai-Yu 82 and Taichung native 1) and 3 N treatments at the panicle initiation stage, but we gained many worthy data (yield curve), fundamental information (nitrogen concentration, color variation in leaf on the growth stage), and some technique (asparagines chromatography, Iodo reaction) on all typical variety for subsequent experiment.
