Abstract:Background
The determination of nutrient content in the petiole is one of the important methods for achieving cotton fertilization management. The establishment of a monitoring system for the nutrient content of cotton petioles during important growth periods under drip irrigation is of great significance for achieving precise fertilization and environmental protection.
Methods
A total of 100 cotton fields with an annual yield of 4500–7500 kg/ha we… Show more
