1980年,笔者在铜鼓县太阳岭,分四个海拔梯度,较系统地观察调查了二化螟发生期及化性的特点,为山区二化螟的预测预报提供参考资料。研究点概况铜鼓县地处东径114°32′,北纬28°32′。各海拔高度点日平均气温,240米和410米处相等,但240米处白天温度较410米处高;610米处比410米处低1.6℃;810米处比610米处低1.6℃。240米处以双季稻为主的单双季混栽区,4月19日开始栽插早稻。其余各点为纯单季稻区,5月17日开始插秧。
In 1980, in Taiyangling, Tonggu County, the author observed the occurrence period and its chemical characteristics of Chilo suppressalis (Stricum Chilo) in a systematic way at four altitudinal gradients, providing references for forecasting Chilo suppressalis in the mountainous area. Overview of the Research Point Tonggu County is located at 114 ° 32 ’east and 28 ° 32’ north. The average daily air temperature at each point is 240 and 410 meters. However, the daytime temperature at 240 meters is higher than that at 410 meters. The 610 meters is 1.6 degrees lower than 410 meters. The 810 meters is 1.6 degrees below 610 meters. 240 meters at the double crop of rice-based single and double mixed planting area, April 19 began planting early rice. The rest of the points for the purely single season rice area, May 17 planting.
