摘要
大豆为子叶出土作物,土壤结皮严重影响大豆出苗质量。本文综述了土壤结皮的形成原因和过程、土壤结皮对土壤和农作物的影响。针对我国黄淮海地区土壤结皮给大豆出苗带来的不利影响,还简述了秸秆覆盖对抑制土壤结皮形成的作用效果,以期为黄淮海地区大豆的生产提供技术参考。
Soybean is a dicot crop and its emergence requires the pull of cotyledon out of soil surface. Soil crusting influences the quality of seed emergence. This review illustrates the cause of formation and process of soil crusting, influence of soil crus- ting on soil and crop and the inhibitive effect of straw-mulching on soil crusting. Due to the influence of soil crusting on soy- bean production in the Huang-Huai-Hai River Valley, this review may provide technique support for soybean production in this area.
