What is Effects of Application of Nitrogen, Phosphorus and Potassium on Soil Fertility and Enzyme Activities of Pear Jujube Under Straw Mulching about?
Abstract In this experiment, the effects of different fertilization treatments on soil nutrient content and enzyme activity under straw mulching conditions were studied by using the soil of jujube garden for 4 consecutive years. The results showed that different fertilization treatments significantly improved the soil fertility of the pear jujube garden in the loess hilly region. In the vertical section of the soil, the soil organic matter content decreased with the increase of soil depth, showing 0∼20 cm>20∼40 cm>40∼60 cm. And the total nitrogen content ofN3P3K1 was the highest at 40∼60 cm, which was 0.28 g/kg, which was 47.4% higher than that of CK. The available phosphorus content of N3P3K1 treatment was higher than other treatments at 20∼40 and 40∼60 cm, and its content was 4.4 and 3.6 g/kg. Different fertilization treatments affected soil enzyme activities. The urease activity of N3P3K1 treatment was 299.27 μg/g, which was 88.2% higher than that of CK. The effect of single application of phosphate fertilizer was the most significant, 54.17 μg/g, which was 98.1% higher than that of CK. Comprehensive analysis N3P3K1 treatment can more effectively improve soil fertility, improves
