干热风是我区西部河套和土默川一带的重要农业气象灾害。但在自然条件下不是每年都有发生,且年际间发生时期、强度、持续时间和对小麦危害程度又不相同,这给研究工作带来了困难。为了增加机遇,缩短试验周期,提高研究质量,确定数量指标,我们参照甘肃、安徽等地有关干热风模拟装置,设计了我院的“人工模拟干热风箱”。本箱结构分为三个部分: 1.干热风发生器:(图2～4)采用电热丝
Dry and hot wind is an important agricultural meteorological disaster in the western Loop and Tumochuan area in our district. However, it does not happen every year under natural conditions, and its occurrence intensity, duration and degree of harm to wheat are different from one another, which brings difficulties to the research work. In order to increase opportunities, shorten the test cycle, improve the quality of research and determine the quantitative indicators, we have designed the artificial simulated dry-air bellows of our hospital with reference to the dry-hot wind simulation devices in Gansu and Anhui. The box structure is divided into three parts: 1. Dry hot air generator: (Figure 2 ~ 4) using electric wire
