Based on nationwide NDVI development graphs over this monitoring period, mostly above average crop condition prevails in Canada. The period covers the harvesting season of winter crops and early growing season of 2016 summer crops. Three major crop production provinces were dominated by good weather and abundant precipitation: Alberta (RAIN, +16%), Manitoba (RAIN, +23%), and Saskatchewan (RAIN, +16%). On the contrary, insufficient precipitation occurred in eastern provinces, such as Ontario (RAIN, -28%) and Quebec (RAIN, -22%) which are the major areas of maize production. According to the NDVI profile clusters, areas with favorable summer crop condition occur in Quebec, southern Ontario, and Alberta, as well as in Southern Manitoba and Saskatchewan, with VCIx greater than one (indicating exceptionally good crop condition). Below average conditions have developed from May in 14.9% of cropped ares, mostly in the east. Adequate soil moisture (compared to the five-year average), resulted in a cropped arable land fraction (CALF) increasing 1 percentage point at the expense of fallow land. While winter wheat did well, the present outlook for summer crops is mixed, especially in the east, and the final outcome of the season will largely be conditioned by summer rain.
全国尺度的NDVI过程线表明,监测期内加拿大作物的整体长势明显好于去年同期平均水平。2016年4-7月的监测期,涵盖夏粮作物的收获期与秋粮作物的关键生长期。加拿大三大粮食主产省的降水量较过去15年同期平均水平偏高,其中艾伯塔、曼尼托巴、萨斯克彻温的降水量分别偏高16%、23%与16%。但与此相反,加拿大东部地区的降水量不足,其中安大略省、魁北克省的降水量较过去15年同期平均水平分别偏低28%与22%。NDVI过程线聚类分析表明,在魁北克的零星地区、安大略省南部,艾伯塔省、曼尼托巴、萨斯克彻温南部地区的最佳植被状态指数(VCIx)大于1,作物长势喜人。但与此同时,在加拿大的东部地区,自2016年5月以来,占全国约14.9%的作物种植区的长势不如往年平均水平。充足的降水有效补充了土壤墒情,与近过去5年同期平均水平相比,耕地种植比例(CALF)偏高1%。尽管冬小麦的作物长势表现抢眼,但是CropWatch监测表明,2016年加拿大粮食产量喜忧参半,特别是东部地区,形势较为复杂。如果大草原良好的天气持续,东部地区的天气状况改善,CropWatch预计加拿大作物总体产量将好于去年。
