籽粒苋的高产抗逆特性及其开发优质高效青贮饲料的关键技术

High yield and resistance to adverse circumstances of grain amaranth and the key technology of high efficiency silage feed

籽粒苋植株高大、枝叶茂盛,具有根系发达、抗逆性强、光合强度高、再生性强四大高产抗逆特性。近年来,我国成功地将它开发成为一种青贮饲料,本文介绍了籽粒苋用作饲料在国内外的开发现状,并针对籽粒苋高产抗逆特性的生物学依据以及建立优质、高效青贮饲料的生态工程关键技术进行了综述,今后以全面应用生态工程技术与纳入生态文明建设体系为发展方向,则其生态经济效益将会倍增。

The grain amaranth has 4 characteristics of high plant height with abundant branches and leves,developed root system,strong resistance to adverse circumstances,high photosynthesis intensity and high power of regeneration.In recent years we have successfully developed it to be an ensilage.In this paper the developing present situation of grain amaranth used as a forage in home and abroad has been introduced,and the biological basis of high yielding and resistance to adverse circumstances and building the key technics of high quality,high efficiency eco-engineering were summarized.From now on the eco-engineeing should bring into eco-civilization construction system as the developing direction,the eco-economic effect would be increased times.
