目前关中小麦正在孕穗、抽穗,陕南盆地小麦正在扬花结籽;陕北小麦已经拔节各地棉花也基本种完,正在出苗。但自4月以来,除陕南部分地区雨量较多外,全省大部地区雨量很少。据气象预报,5月份雨量也较往年为少。而小麦从拔节到灌浆,是全生长期需水最多的阶段。这一时期所需水量占全生长期总需水量的55%以上,日耗水量达到每亩4公方。尤其在高肥、密植和最近多风的情况下,耗水量更加增大,关中、陕北和商雒地区已呈旱象,隶进行春灌的棉田部分出苗困难。最近泾、洛等不少灌区由于水量不足,发生争水现象。因此,立即动员起来开展以夏田灌溉为中心的防旱工作,就成为确保实现粮棉增产指标的重要关键和紧迫任务。为此,特作以下通知:
At present, Guanzhong wheat is booting and heading. The wheat in the southern Shaanxi basin is blooming and seedling. The northern Shaanxi wheat has also been basically planted and cotton is being sprouted throughout the spring. However, since April, rainfall in most parts of the province has been very low, except for more rainfall in parts of southern Shaanxi. According to the weather forecast, the rainfall in May is also less than in previous years. The wheat from jointing to grouting, is the most all-stage water needs of the stage. The amount of water required during this period accounted for more than 55% of the total water demand for the whole growth period, and water consumption per day reached 4 square meters. Especially in the areas of high fertility, close planting and the recent windy weather, the water consumption is even more increased. In Guanzhong, the northern part of Shaanxi Province and Shangliu Area have been characterized by arid areas, and part of the cotton fields under spring irrigation are experiencing difficulties in emergence. Recently Jing, Luo and many other irrigated areas due to insufficient water, water dispute occurred. Therefore, immediately mobilizing drought relief efforts centered on summer field irrigation has become an important and urgent task in ensuring the realization of the target of increasing the output of grain and cotton. To this end, made the following special notice:
