厚皮甜瓜是最喜温耐热的作物之一,极不耐寒,遇霜即死。目前对厚皮甜瓜不同生育阶段的适宜温度研究的比较详细,但对厚皮甜瓜的冷害问题研究的较少。而在生产中,特别是冬春保护地栽培时,经常遇到不同程度的低温天气,对厚皮甜瓜的正常生长产生不良影响,以至造成不同程度的伤害,其中以冷害影响最大。现结合多年的研究和实践经验,对厚皮甜瓜冷害的发生及预防措施简述如下。一、冷害的涵义所谓冷害,就是在植株组织液冻结临界温度以上,由于不适当的低温对其造成的各
Thick-skinned melon is one of the hottest warm crops, very cold, frost that death. At present, the optimum temperature of muskmelon in different growth stages is studied in detail, but there are few studies on the chilling injury of muskmelon. In the process of production, especially in the winter and spring, it often encountered different degrees of cold weather, which had an adverse effect on the normal growth of the muskmelon, causing different degrees of harm, of which chilling injury was the most affected. Now combined with many years of research and practical experience, the incidence and preventive measures of chilling injury melon thick as follows. First, the meaning of cold damage The so-called cold damage is the plant tissue fluid freezing above the critical temperature, due to improper low-temperature caused by its
