查询词典 variability

Taking a winter wheat field (4 400 m2) of Jinghai county seed farm as experimental plot,sampling by regular grid with with 10 m ×10 m grids,48 sample points were oriented by GPS receipt machine to analyze soil water content at the depth of 0~20 and 20~40 cm in pri-winter,jointing stage and filling stage of winter wheat.The spatial distribution map of soil water of the winter wheat field using geostatistical analyst model of ARC/INFO was drew.And the spatial variability of soil water in vertical and horizontal direction was analyzed.The results could offer scientific evidence for the deciding of the exact time and quantity for winter irrigation.
