作物生长指标与土壤水分状况及地温关系研究
Study on the Relation of Soil Moisture and Soil Temperature to Crop Growth
摘要
Abstract
Crop growth and soil moisture, soil temperature are of importance for design of irrigation schedule and are significant for improving water use efficiency and crop growth. The influences of soil moisture, soil temperature, laminating and super absorbent polymer on stem diameter and yield of silage corn were analyzed based on the experimental data. The results show that: plastic film mulch is the best technology of corn silage that is fond of heat and water, plastic film mulch can maintain soil temperature and soil moisture, followed by use of super absorbent polymers that is immersed seed than used channel. The air temperature and soil moisture are major factors of the changes soil temperature, sufficient irrigation is not good to crop growth because adequate water reduced the soil temperature, therefore, non-sufficient irrigation can be used in relative shortage of water resources in northern and cold regions.关键词
