Analysis of Seasonal Dynamic Characteristics and Nutrient Effects of Soil Nutrients in Apple and Sweet Potato Intercropping System in Sandy Land of Northwest Liaoning Province
The dynamic changes of soil nutrients in apple and sweet potato intercropping system in different seasons and the nutrient effects of single planting were compared and studied.The results showed as follows:the overall nu-trient content of the intercropping system showed a downward trend,but the nutrient consumption was the most in July,and the nitrogen and potassium in the nutrient needed to be replenished in time,while the phosphorus consump-tion was less;the consumption of total nitrogen and available potassium in intercropping system was less than that in sweet potato monoculture,but the overall nutrient consumption was more than that in apple monoculture.
