1.低温冷害是造成东部山区粮食产量不高不稳的主要自然灾害,因此研究低温冷害规律,采取综合的有效的防御措施是解决本区农业生产的主要课题。2.高寒山区防御低温冷害的主要技术措施是:(1)改土增肥,提高地力;(2)提早播种,秋霜春防;(3)增施磷肥;(4)科学用种,合理搭配。3.合理利用山区资源,积极发展林业、牧业,为粮食生产创造出良好的生态环境和提供充足的肥料来源,进一步提高抗御低温冷害等各种自然灾害的能力,使农业生产建立在高产稳产基础上。
1. Low-temperature chilling damage is the major natural disaster that causes low and unstable grain yield in eastern mountainous areas. Therefore, studying the law of low-temperature chilling injury and adopting comprehensive and effective defense measures are the main topics for solving this problem. (2) early sowing, autumn frost spring prevention; (3) the application of phosphate fertilizer; (4) the scientific use of species, with a reasonable mix of the main technical measures to prevent cold damage in alpine mountain areas are: (1) . 3. Make rational use of mountain resources, actively develop forestry and animal husbandry, create a good ecological environment for food production and provide sufficient sources of fertilizers, and further enhance the ability to resist various natural disasters such as chilling damage and cold damage, so that agricultural production can be built on the basis of high and stable yield basically.
