牧草种子的收获时期是否适当,直接影响牧草种子的产量和品质。收获过早,种子成熟的不好,会影响发芽率和千粒重,使品质不佳;收获过晚,则会因牧草易于脱落,而使饱满的种子大量损失,造成减产. 牧草种子的最佳收获期,主要根据种子的成熟度来确定。成熟度通常分为乳熟期、蜡熟期和完熟期三种。乳熟期的种子表面为绿色,种皮内为白色乳状 The proper harvesting period of forage seeds directly affects the yield and quality of forage seeds. Premature harvest, poor seed maturity, will affect the germination rate and 1000-grain weight, poor quality; harvest late, it will be because of the grass easy to fall off, leaving plump seeds lost a lot, resulting in reduced yield. The best harvest of forage seeds Period, mainly based on the maturity of the seed to determine. Maturity is usually divided into milky maturity, wax maturity and maturity of three.
