This report summarizes the rice production conditions in Vietnam. Summer and autumn rice harvesting has been completed, while late rice is still in its growing season. Precipitation over the nation increased nearly 13% as compared to the 15-year average. South Central Coast (+25%) and Northern Vietnam(+21%) are the two regions received the highest precipitation, which alleviated the drought condtions which were observed during the previous reporting period. Apart from precipitation, temperature (+0.2 °C) and RADPAR (-+%) were slightly above average.
本报告涵盖越南大米的生长状况，监测期内夏秋水稻收割完成，而晚稻仍处于生长期。 与过去15年同期平均水平相比，全国降水量偏高13％， 中南部沿海地区（偏高25％）和越南北部（偏高 21％）为降水最高的地区，这缓解上期报告所述的干旱情况。 除降水量外，平均气温（偏高0.2°C）和光合有效辐射（偏高1％）略高于平均水平。
Crop condition development based on NDVI was significantly lower than the 5YA. Apart from the Red river Delta and the North West region , all the regions had a similar pattern of NDVI, starting close to the average and ending below average in October. VCIx was generally above 0.8, except for the South Central Coast and the coastal provinces of the Mekong Delta where VCIx was low. The CALF was stable as compared to the recent five-year average. Vietnam was hit by a series of typhoons in October. Most of the rice had been harvested by then.Due to slightly unfavorable crop conditions and stable cropped areas, crop outputs are estimated to be slightly below normal
基于NDVI的作物生长过程线明显低于近5年平均水平， 除红河三角洲和西北部外，所有地区NDVI变化趋势均相似，初始期接近平均值随后在10月份低于平均水平。 除中南部沿海地区和湄公河三角洲部分省份（VCIx较低）以外，最佳植被状况指数（VCIx）均高于0.8。 与近5年同期平均水平相比，耕地种植比例保持稳定。十月份越南遭受了一系列台风侵袭，而大部分稻子已经收割完毕。 总体而言，略有不利的作物生长条件以及稳定的作物种植面积使得作物产量略微低于正常水平。
