The optimum fertilization rate , population density and variety in these experiments have recommended to farmers 已将试验所得最佳施肥量、种植密度和品种推荐给农民。
Initial growth of crop stands can be easily obtained by an increase of planting density or by application of increased level of basal fertilizers 作物苗的早期生长很易由提高种植密度或增施基肥获得。
Effect of plant density and fertilizer application on plantain yield in two soils from colombia with different natural fertility is shown ( table 2 ) 表2说明了在哥伦比亚的两种不同天然肥力土壤上种植密度及肥料用量对大蕉产量的影响。
Plant population varies from 1 , 400 to 1 , 600 plants per hectare and the plantation is kept in the field for several ratoons using suckers coming from the mother plant 种植密度保持在1400株/公顷到1600株/公顷,种植园田地上留下母株的根出条所形成的截根苗。
