复合肥施用量对云薯902农艺及产量性状的影响

Effects of Application Rate of NPK Compound Fertilizer on Agronomic and Yield Traits of Yunshu 902

为玉溪市马铃薯生产提供科学依据,在玉溪农业职业技术学院农林系农场进行了起垄栽培不施肥(CK),施三元复合肥(N∶P∶K=15∶15∶15)50kg/667m2、100kg/667m2和150kg/667m2对马铃薯新品种云薯902农艺及产量性状的影响试验。结果表明:与CK相比,施用三元复合肥有利于云薯902植株生长和产量性状的提高。其中,以云薯902施用三元复合肥100kg/667m2的效果最好,产量高达2 189kg/667m2,纯收益为883.50元/667m2。

To provide a scientific basis for potato production in Yuxi City,the experiment on the agronomic and yield traits of the new potato variety Yunshu 902 was carried out in the agriculture and forestry farm of Yuxi Agricultural Vocational-Technical College.Four levels were set,including no fertilization(0 kg/667m^2),normal fertilization(50 kg/667m^2),high fertilizer(100 kg/667m^2)and super high fertilizer(150 kg/667m^2).Results:Compared with CK,the application of ternary compound fertilizer was beneficial to the growth and yield of Yunshu 902.Among them,the application of ternary compound fertilizer 100 kg/667m^2 with Yunshu 902 was the best,the yield was as high as 2 189 kg/667m^2,and the final net income was 883.50 Yuan/667m^2.
