杂交高粱的增产潜力很大,但由于种杂交高粱是一个新生事物,人们还没完全认识它,还没摸清种好它的规律,常常因为保不住苗而毁种,因缺苗和管理不善而减产。因而没能发挥杂交高粱的增产作用。 Hybrid sorghum yield potential is very large, but because of the hybrid sorghum is a new thing, people have not fully understand it, have not figured out the law to grow it, often because of seedlings can not be destroyed, due to lack of seedlings and poor management Cut Thus failed to play a role of hybrid sorghum yield.
