不同施肥处理对枳及柠檬容器苗生长的影响

摘要

研究9个不同施肥处理对枳及柠檬容器苗生长的影响.结果表明:不同施肥处理对枳容器苗的苗高、地径、分枝高度及嫁接后柠檬苗的发芽率、株高、茎粗、分枝数及生物量都存在显著差异;不同施肥处理对枳及柠檬容器苗综合表现最好的为T4(撒施柠檬专用肥1.6 g)处理,其次是T2(撒施尿素0.6 g)、T3(撒施柠檬专用肥0.8g)处理,表现最差的是T8(浇施5％柠檬专用肥)和T7(浇施3％柠檬专用肥)处理.在一定施肥浓度范围内,施肥对嫁接后柠檬容器苗的生物量积累有明显促进作用.柠檬容器苗培育时建议采用在基质中撒施柠檬专用肥1.6 g.%In recent years,with the development of the industry of lemon,lemon container seedlings were widely used.In this experiment,nine different fertilization treatments were designed to study the influence on the container seedling growth of P.trifoliate and C.limon (L.).The results showed that the differences of seedling height,ground diameter,branching height,lemon seedlings after grafting of germination rate,plant height,stem diameter,branch number and biomass were significant under different fertilization treatments.The best comprehensive performance was T4 treatment (sprinkling lemon special fertilizer 1.6 g) followed by T2 (sprinkled urea 0.6 g),T3 (sprinkling lemon special fertilizer 0.8 g).The worst performance was T8 (pouring 5％ lemon special fertilizer) and T7 (pouring 3％ lemon special fertilizer).Fertilization had a significant effect on the biomass accumulation of the grafted lemon container seedlings within a certain fertilization concentration range.1.6 g of lemon special fertilizer sprinkled with the media was recommended for lemon container seedling cultivation.
