串叶松香草原产于北美中部潮湿高草原地带,是一种优质饲料作物,据报道其产量和饲用价值都优于向日葵、玉米、甜高粱、苜蓿和聚合草。我所于1982年引入幼苗,后又引入原种,经过在我所植物园连续3年的观察,松香串叶草越冬性很好,直播和移栽保苗都很容易,在肥力中等、施肥充足、适时灌溉的栽培条件下产量可达0.75—1万公斤,可作为集约型高产栽培饲料作物推广。
It is reported to be superior in yield and feed value to sunflower, corn, sweet sorghum, alfalfa, and polymerized grass, a native forage crop that is native to the moist, high grasslands of central North America. I introduced the seedlings in 1982, and then introduced the original species. After 3 consecutive years of observation in our botanical garden, the overwintering sex of the rosin is very good. It is very easy to live and transplanting the seedlings, medium fertility, adequate fertilization, Yield under timely irrigation cultivation conditions up to 0.75-1 million kg, can be used as an intensive high-yield cultivation of forage crops to promote.
