不同类型土壤对饲用早稻产量与米质的影响

为进一步挖掘饲料专用早稻产量潜力，提高其糙米蛋白质含量，通过总结专用稻栽培技术，选取了湖南省五类土壤，研究饲料专用早稻的产量和稻米品质变化。结果表明，五类土壤种植的饲料专用早稻产量以黄泥（6358.5 kg/hm2）为最高，其次为灰黄泥（6295.5 kg/hm2），产量表现为黄泥 > 灰黄泥 > 红黄泥 > 紫潮泥 > 中性紫泥；黄泥、灰黄泥、红黄泥比紫潮泥、中性紫泥的饲料稻全生育期缩短1天；灰黄泥具有较高的糙米率和蛋白质含量，糙米率为80.1%，蛋白质含量为12.2%。综合分析，饲料专用稻的产量、生育期和米质特点，认为最适宜种植饲用稻的土壤为灰黄泥，其次是黄泥和红黄泥。

Effects of Soil Types on Yield and Quality of Forage Rice

In order to improve the output of forage rice,brown rice,protein content,this study selected five soils in Hunan Province to study the forage rice in the yield and quality changes.The results showed that five types of soil forage rice yield yellow clayey paddy soil was the highest 6358.5 kg/hm~2,followed Grey-yellow soil 6295.5 kg/hm~2 yield performance for the yellow clayey paddy soil>grey-yellow soil>redish yellow clayeyp addy soil>calcareous loamy paddy soil>neutral purplish clayey soil.Yellow clayey pad...
