纯作头刀薄荷的特点是基本苗较足,苗期、分枝期光照充足,前、中期植株生长条件好。在肥力中上等或虽土质瘦瘠而施入一定数量基肥的田块中,早期释放出的养分已能满足薄荷前、中期生长之需,如果在前、中期施肥过多,会造成前、中期生长过旺,茎杆细软,中后期发生倒伏,或因养分被前期消耗过多,叶片与分枝产生少,且使叶片脱落率增高,降低鲜草产量和鲜草得油率。为探讨最佳施肥方法,
Pure head knife mint is characterized by more than adequate basic seedlings, seedling stage, sufficient branching period, before and during the growth of good plant conditions. Fertility in the finest or even though the soil is thin and barren and put a certain amount of base fertilizer in the plots, the early release of nutrients to meet the needs of the menthol before and during the growth, if the former, medium fertilization, will cause before, Medium-term over-growth, stem thin and soft, lodging in the late, or because nutrients are consumed too much, leaves and branches produce less, and the leaves off rate increased, reducing fresh grass yield and fresh oil yield. To explore the best method of fertilization,
