去年,我区因水源准备不足等原因,有的地方晚稻中、后期脱水,造成干旱面积达58万亩,一般减产2—3成,其中有4万余亩损失稻谷70%。脱水过早,形成干旱,使稻株体内水分亏损,破坏了新陈代谢的协调性,影响了光合作用和养分转运过程的顺利进行。因而导致减产。据调查,因脱水过早,造成干旱的危害主要表现在以下几个方面: Last year, due to inadequate water preparation in some areas, dehydration in late rice occurred in some areas, resulting in a dry area of ​​580,000 mu and a general reduction of 2-3%, of which more than 40,000 mu lost 70% of the paddy. Premature dehydration, the formation of drought, rice plant water loss, undermining the coordination of metabolism, affecting the photosynthesis and nutrient transport process smoothly. Thus leading to cut production. According to the survey, due to premature dehydration, the damage caused by drought mainly in the following areas:
