Based on the global NDVI profile, CropWatch conjectures above average crop condition for the United Stated This reporting period covered the harvesting season of winter crops and the core of the growing season of summer crops.

基于整体的植被归一化指数（NDVI）过程线，CropWatch监测结果表明监测期内作物的长势好于多年平均水平。此监测期包含夏粮作物的收获期与，秋粮作物的关键生长期。

In general, weather was normal in the United States: CropWatch agroclimatic indicators recorded an 8% increase in precipitation, a 0.3°C drop in temperature, and a 1% drop in radiation at the national level. In the major production zones abundant rainfall was recorded. The main production zone for winter crops also received abundant rainfall, including in Kansas (RAIN, +56%), Oklahoma (+40%), and Texas (+45%) where serious floods occurred in June. Plentiful precipitation was also recorded in the northern Plains and western Great Lakes, including Nebraska (+38%), South Dakota (+37%), North Dakota (+55%), and Minnesota (+38%, resulting in floods in July). In the Corn Belt, normal or above average rainfall was recorded in Wisconsin (+7%), Indiana (+4%), Illinois (+10%), and Iowa (+13%), while Ohio (-22%) and Michigan (-27%) suffered a water deficit. As the most important rice producing state, Arkansas received above average rainfall (+11%), which benefited the growth of paddy.

整体而言，美国的天气状况正常，CropWatch农气指数监测表明，监测期内降水量较过去15年同期平均水平偏高8%，温度偏高0.3℃，光合有效辐射偏低1%。美国主要的粮食主产区，监测期内的降水都较为充足。以冬小麦为例，堪萨斯、俄克拉荷马与、德克萨斯的降水量分别偏高56%、40%与45%，在德克萨斯州的局部地区，2016年6月，强降水还引发较为严重的洪涝灾害。在大平原的北部地区以及五大湖的西部地区，内布拉斯加、南达科他、北达科他、明尼苏达州的降水量较过去15年同期平均水平相比，分别偏高38%、37%、55%与38%，在明尼苏达的局部地区，还发生较为严重的洪涝灾害。在美国的玉米带，降水呈现分化现象，南部的威斯康辛、印第安纳、伊利诺伊与、艾奥瓦的降水分别偏高7%、4%、10%与13%，但在东部与北部的俄亥俄、密歇根的降水量分别偏低22%与27%，作物水分胁迫明显。在美国最为重要的水稻主产区——阿肯色，监测期内的降水量较往年同期平均水平偏高11%，为水稻的生长提供了较为充足的水分补给。

Without doubt, the predominantly humid weather provided enough soil moisture for crop growth. In major parts of the southeastern United Stated (including Arkansas, Louisiana, Alabama, Tennessee, and Florida), good crop condition is confirmed by NDVI cluster profiles and positive departure of crop condition development. Good production of paddy and cotton is to be expected this year. Although the states suffering from some floods, the good crop condition in winter crop states (Kansas, Texas, and Oklahoma) is also supported by positive NDVI departures. In the Corn Belt, crop condition in the south and east (including Illinois, Iowa, and Indiana) shows positive departures, while in the western and northern Corn Belt (Minnesota, Michigan, and Wisconsin) and northern Plains (North Dakota and South Dakota), crop condition was below average, resulting possibly from water deficit or excess.

毫无疑问，监测期内以湿润气候为主导的天气状况为作物的生长提供了丰富的水源补给。NDVI聚类过程图与距平图及相应的类别过程线分析表明，美国东南部主要的粮食生产州的作物长势都好于往年同期平均水平，CropWatch预计2016年美国水稻与棉花的产量向好。就美国冬小麦主产区（堪萨斯、德克萨斯与、俄克拉荷马）而言，尽管德克萨斯的局部地区遭遇严重的洪涝灾害，但NDVI距平分析表明，该地区整体的作物长势好于多年同期平均水平。在美国玉米带，作物的长势呈现分化状况，在玉米带的南部与东部地区，如伊利诺伊、艾奥瓦和俄克拉荷马的作物长势好于多年同期平均水平，但是在玉米带的西部（明尼苏达、威斯康辛）与北部地区（密歇根），以及大平原的北部地区（北达科他、南达科他），因作物水分胁迫或水涝的影响，作物长势不如往年同期平均水平。

In this monitoring period, the seeded area also increased 1% compared to the recent five-year average as a result of sufficient soil moisture. Altogether, crop prospect are favorable.

就耕地作物种植比例而言，得益于充足的土壤水分补给，已种植作物的耕地面积较近过去5年同期平均水平偏高1%。综上所述，CropWatch预计2016年美国作物的整体状况向好。
