为了循环利用农业生产资源,探索科学改良土壤的方法,将菌糠、秸秆、锯木屑、稻壳4种有机物下脚料添加到土壤,考察其对土壤的改良效果。结果表明:在土壤中添加有机物能有效提高地温并减少水分蒸发;其中添加菌糠和秸秆可使蔬菜极显著增产,而添加锯木屑和稻壳的当季增产效果不显著。
In order to recycle agricultural production resources and explore ways to scientifically improve the soil, four kinds of organic waste such as chaff, straw, sawdust and rice husk were added to the soil to investigate the improvement effect on the soil. The results showed that adding organic matter to the soil could effectively increase the ground temperature and reduce the evaporation of water. The addition of bran and straw increased the yield of vegetables significantly, while the yield increase of sawdust and rice husk was not significant.
