控释肥对土壤和平邑甜茶养分含量及生长的影响
Effects of Controlled Release Fertilizer on Soil Nutrient Content and Growth of Malus hupehensis Rehd.
摘要
Abstract
The field experiment was conducted to study the effects of controlled release fertilizer on soil nutrient content and growth of Malus hupenensis. The results showed that the releasing rate of controlled release fertilizer increased firstly and then decreased after reached the peak. The controlled release fertilizer could meet the nutrient requirement of Malus hupenensis in growth period and promoted its growth. Having the same fertilization rate with T2 treatment, the T3 treatment increased the plant height, stem diameter, dry weight and the contents of N, P and K in branch 17.69%, 10.89%, 31.98%, 54.29%, 22.5% and 61.43% respectively, as well as T4 and T5 treatments with less fertilization rate compared to T2 treatment. In conclusion, the T5 treatment with 320 kg/hm2 N, 120 kg/hm2 P2O5 and 400 kg/hm2 K2O was the best under the experiment conditions.关键词
