土壤图层,趁地表裸露时获取。

选定一片田块,即可获得秸秆覆盖度、耕作类别、黏土与石膏吸收深度,以及基于裸土合成影像的相对有机质指数。

What people bring us, and how we handle it.

在全县范围核查秸秆覆盖

在彩色影像中,风化残茬与裸露矿质土壤看起来一样。

干残茬的纤维素特征可按秸秆覆盖度为田块排序,这是宽波段绿度指数看不到的。

决定土壤取样点的位置

网格取芯每个点成本高昂,点与点之间的插值又很不可靠。

对整个影像库做裸土合成,得到覆盖全田的相对指数,足以指导取样点布设。不报告碳含量。

在损失一季收成之前发现盐渍化

盐渍化通常在减产、土壤结壳之后才被注意到。

石膏水合与黏土特征在干燥裸土上同时读取,在产量受损之前筛查盐渍化。

FREQUENTLY ASKED QUESTIONS

Questions we get asked about this sector.

干残茬含纤维素和木质素,在短波红外有吸收。裸露矿质土壤在同一波段区间基本平坦。秸秆覆盖度正是建立在这一差异之上。
