不同施氮量对百香果扦插苗生长及根际土壤养分含量的影响
Effects of Different Nitrogen Application Rates on Growth of Passiflora edulis Sims Cuttings and Nutrient Content of Rhizosphere Soil
摘要
Abstract
In order to promote the scientific application of nitrogen fertilizer in the production practice of Passiflora edulis Sims,the test under the condition of pot culture,taking no fertilization treatment as the control(T1),five nitrogen application treatments with nitrogen application rate as 4 g per plant(T2),6 g per plant(T3),8 g per plant(T4),and the effects of different nitrogen application rates on nutrient content in rocky desertification soil and growth of Passiflora edulis Sims was studied.The results showed that:on the 100th day after treatment,the fresh weight of T4 treatments was significantly higher than that of other three treatments;the contents of total phosphorus and available phosphorus in the soil of each fertilization treatment were higher than those of the control,there was no significant difference between T4 and T3;the content of soil available potassium in each fertilization treatment was significantly lower than that of the control on the 100th day.Comprehensive analysis showed that when the nitrogen application rate was 8 g per plant,the effect was obvious to promote the growth of Passiflora edulis Sims cuttings and improve the nitrogen content in rhizosphere soil.关键词
