Study on early maturity and high yield cultivation technology of potato considering quality input parameters

[Objects] In order to determine the best parameter of potato early-maturing and high-yield cultivation technology, the early-maturing and high-yield cultivation technology considering quality input parameters was studied. [Methods] Four varieties of early-maturing potato, Zaodabai, Zihuabai, Kexin 6 and Dongnong 303, were selected as experimental materials. Sowing time, fertilizer formula and pest control were selected as quality input parameters, the plant height, weight, stem diameter, leaf area index, potato yield and vitamin C were selected as potato quality evaluation parameters, and the effects of different quality input parameters on early maturity and high yield of potato were determined. [Results] The sowing time of potato cultivation was about March 1, and the formula of fertilization was 160 km2 of N, 150 km2 of P2O5, and 105 km2 of K2O. When comprehensive pest control measures were adopted, the potato had the best quality and the highest yield. [Conclusion] The yield and quality of potatoes can be improved by adjusting sowing time, fertilization formula and formulating effective pest control measures.
