低温寒害是农业生产中一种严重的自然灾害,涉及的面很广,包括粮食作物、蔬菜、果树、园林及其他许多经济作物。水稻是我国的主要粮食作物,种植面积居各种作物之首位,达5亿多亩,其早春育秧中的低温烂秧问题,从北到南几乎年年都有发生,不仅造成稻种的巨大损失,而且延误农时,导致严重减产。鉴于此种情况,我们在多年研究植物抗寒机理的基础上,提出了“水稻育秧抗寒剂”的研制目标。经过长达6年的从实验室、盆栽到大田的系统试验,现在已经取得了较为理想的结果,有待广泛推广。
Chilling damage is a serious natural disaster in agricultural production and involves a wide range of food crops, vegetables, fruit trees, gardens and many other cash crops. Rice is the main food crop in our country. The planting area occupies the first place of all kinds of crops, reaching over 500 million mu. The problem of low-temperature rotting seedlings in early spring seedling growing occurs from north to south, which has not only caused the huge Loss, but also delay farming, leading to serious cuts. In view of this situation, on the basis of years of research on the mechanism of plant cold resistance, we put forward the research goal of “rice seedling cold-resistant agent”. After 6 years of systematic experiments from the laboratory, potted plants to the field, we have now achieved satisfactory results and are yet to be widely promoted.
