马铃薯新品种鄂马铃薯7号高产栽培试验

为加速推广马铃薯新品种,本研究以鄂马铃薯7号为试材,在高低两个海拔高度进行不同种植密度、不同底肥种类的高产栽培试验。种植密度设计每667 m2 3 500株、4 400株、5 400株3个水平,底肥设计每667 m2施牛粪2 500 kg、复合肥25 kg、复合肥10 kg+过磷酸钙25 kg 3个水平。结果表明:无论低山还是二高山地区鄂马铃薯7号的最佳种植方式是667 m2种植密度5 400株、底肥为复合肥25 kg,667 m2平均产量达2 324.5 kg。

Cultivation Techniques for High Yielding of Potato New Variety E-malingshu 7

Experiments with various plant densities and basal fertilizers were carried out in two locations of various latitudes by using the variety E-malingshu 7 with the aim to extend the new potato variety extensively.The plant densities were set at 3 500 hills,4 400 hills and 5 400 hills,and basal fertilizers were 2 500 kg cow dung,25 kg compound fertilizer,and 10 kg compound fertilizer + 25 kg calcium superphosphate based on 667 m2 of the land.The best performance(tuber yield 2 324.5 kg) was achieved when the variety E-malingshu 7 was planted at 5 400 hill and the basal fertilizer was applied at 25 kg of the compound fertilizer regardless of the locations.
