今年我省遇到了历史上罕见的严重干旱,开春后,淮北就开始出现干早,并逐步发展到苏中和苏南。以后,春旱接“空梅”,空梅接伏旱,伏旱接秋旱,干旱持续了十个多月。我省毛竹基地县宜兴从5月初至9月初,一直干旱少雨,持续时间达120天以上。仅6月23日及8月11日下过二次小雨。此间气温高（日最高气温在35℃以上的日数达30多天）,日照长（平均比往年周期长20％左右）,西南向干热风多,更加助长了旱情的发展。今年宜兴山区毛竹林绝大部分为大年,原发笋长势很好,成竹数量估达500～600万支以上。但在新竹形成过程中,由于道此大旱,对新老毛竹特别是新竹产生了严重危害,并将对今后毛竹的更新和产量发生深远的影响。
This year, our province encountered a rare serious drought in history. After the spring, Huaibei started to dry early and gradually developed into the Soviet Union and southern Jiangsu. After the spring drought then “empty plum”, empty plum then drought, autumn drought drought, drought lasted more than ten months. Yixing, a base county in our province, has been drier and drier since early May and early September, lasting more than 120 days. Only two light drifts occurred on June 23 and August 11. During this period, the temperature is high (the maximum daily sunshine temperature is above 35 ℃ for more than 30 days), long sunshine (about 20% longer on average than in previous years), and more dry and hot winds in the southwest have further boosted the drought. This year Yixing Moso bamboo forest for the vast majority of New Year, the original bamboo shoots grow well, bamboo quantity estimated 500 to 600 million or more. However, in the course of the formation of Hsinchu, due to this drought, the new and old Moso, especially Hsinchu, had a serious harm and will have a profound impact on the future updating and yield of Moso bamboo.
