摘要
秸秆育苗钵是由改性的作物秸秆冷压模塑而成。为了进一步研究秸秆育苗钵的特性,对秸秆育苗钵的吸水保水特性、分解特性、透气性及营养成分进行了比较分析。结果表明,随着秸秆型号的增加,秸秆育苗钵的吸水保水特性及营养成分随之增加;秸秆育苗钵具有良好的吸水性和保水性,大田自然条件下30 d左右即可完全分解,且无污染,同时还可增加土壤养分。
Straw block is a cold pressing molding made of modified crop straw. In order to further study the characteristics of straw block, the paper makes a comparative analysis of the water absorption and retention properties, decomposition characteristics, breathability and nutrient ingredients of straw block. The results show that with the increase of straw types, the water absorption and retention properties and nutrient ingredients of straw block increase; the straw block, which is pollution-free all the time, with its good water absorption and retention properties, can decompose completely in about 30 d under the natural conditions in the field, and can increase simultaneously the soil nutrient content.
