Abstract:

In order to improve the utilization rate of fertilizers, reduce the use of plant regulators, and improve the quality of potato tubers during potato cultivation, the study used a field experiment to study the weight loss and efficiency enhancement effect of applying a specialized polyaspartic acid salts fertilizer synergist during the planting process of potato, under the condition of reducing fertilizer application by 20%. The results showed that under the conditions of applying 15 kg·hm-2 of synergists and reducing fertilizer use by 20%, three specialized synergists increased potato yield by 5.86%-9.47%, and effectively improved the commercialization of potatoes. This indicates that specialized polyaspartic acid salts synergists can effectively reduce fertilizer use and increase potato yield characteristics, with T2 treatment being the most obvious. Meanwhile, the application of polyaspartic acid salts can effectively improve the quality of potato tubers.
