高品质马铃薯的沙地栽培技术研究

Study on the High Quality Cultivation Technology of Potato in a Desert

为了确定马铃薯早熟高产栽培技术的最佳参数,研究考虑品质投入参数的马铃薯早熟高产栽培技术。选择早大白、紫花白、克新6号、东农303四个品种的早熟马铃薯种薯作为试验材料,选取播种时间、施肥配方和病虫害防治作为品质投入参数,选取马铃薯植株茎粗、叶面积指数、马铃薯产量、维生素C等指标作为马铃薯品质评价参数,确定不同品质投入参数对马铃薯早熟高产的影响。马铃薯栽培的播种时间为3月1日左右,施肥配方为35 kg/hm^(2)的N、18 kg/hm^(2)的P2O5、39 kg/hm^(2)的K2O,采用综合性病虫害防治措施时,马铃薯品质最优,产量最高。通过调整播种时间、施肥配方,制定有效的病虫害防治措施,可以提高马铃薯的产量和品质。

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.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,the effects of different quality input parameters on early maturity and high yield of potato were determined.The sowing time of potato cultivation was about March 1,and the formula of fertilization was 160 km^(2)of N,150 km^(2)of P2O5,and 105 km^(2)of K2O.When comprehensive pest control measures were adopted,the potato has the best quality and the highest yield.The yield and quality of potato can be improved by adjusting sowing time,fertilization formula and formulating effective pest control measures.
