Effects of a New Fertilizer Synergist on the Agronomic Characteristics,Yield,and Quality of Potato
To solve the problems of excessive and unreasonable fertilization in potato production and improve the efficiency of fertilizer application,the agronomic characteristics,yield,and quality of the potato variety Quanshu No.5 were studied.The results of the gradient application experiment showed that,compared with the control(750 kg·hm-2),the new synergistic agent had some effect on agronomic characteristics,such as plant height,stem diameter,yield,and potato quality,and improved the fertilizer preservation effect,improved the nutritional quality of potato plants,effectively promoted the growth and development of potato plants and yield formation,and increased the yield of treatment E1.The synergistic agent used was 10%fertilizer(carbase no.1 75 kg·hm-2+compound fertilizer 750 kg·hm-2,and the output of 32 675.03 kg·hm-2,was the highest,increasing the economic performance by 16.80%.The results of the reduce fertilize test showed that there were significant differences in plant height,stem diameter,and yield between treatment F1(carbase no 1 67.5 kg·hm-2+compound fertilizer 675 kg·hm-2)and the control,and the economic benefit of treatment F1 was 56 310.00 yuan·hm-2,which was 3 135.00 yuan/hm2 greater than that of CK.The new fertilizer synergist has a good effect on the agronomic characteristics of potatoes,can promote the growth and development of potatoes,and can increase the economic benefit of potato planting.The goal of reducing fertilizer application and improving the yield and quality of potatoes can be achieved.
