| The method of field experiment and laboratory analysis was used to study the effects of multi-element fertilizers on potato,and the purpose was to provide the basis for the application of potato special formula fertilizer and agricultural production.The main results showed that the aerial formula fertilizer 5,3 and 9 had the most obvious effects on the plant height,of flowering stage and tuber enlargement stage.The effect is most obvious;China Aviation formula fertilizer 4,9,respectively,to promote the seedling,tuber enlargement branch number.The results showed that the aerial formula fertilizer 3 and 5 were the highest in the flowering period and the tuber enlargement period,but the total amount of dry matter accumulation was the highest in the flowering period and the tuber enlargement period.The yield per plant was not significantly different from that of AVF.From the yield per unit area,the yield of CAF was the highest,which was 97.1%higher than that of conventional fertilization.Taking into account,AVIC Formula 3 is a preferred formula for potatoes suitable for Tamarau. |
