以中早熟高产抗病马铃薯品种“坝薯9号”为试验材料,在水浇条件下对马铃薯高额丰产栽培综合农艺措施进行了研究,得到了相应数学摸型,并在生产实际中证实了该模型的实际效果.现将结果简报如下.1 材料和方法以“坝薯9号”脱毒原原种50g～100g整薯作种,采用5因素5水平二次通用回归旋转设计,1/2实施,共32个小区.全部试验一字排列,每隔9～10小区增设一个常规播种的对照.试验地地力均匀一致,前茬为莜麦,0～30cm土层养分含量为:有机质1.771%,全N0.107%,全P_2O_50.150%,全K_2O1.976%,速N115×10~(-6),速P_2O_510.0×10~(-6),有效K_2O
Taking “Zhongshu 9”, a middle-early-maturity, high-yield and disease-resistant potato cultivar, as experimental material, comprehensive agronomic measures of high yield and high yield potato were studied under watering conditions. Corresponding mathematical models were obtained and confirmed in production The results of the present report are as follows.1 Materials and methods to “Damu 9” from the original seed detoxification 50g ~ 100g whole potato as a species, the use of 5 factors and 5 levels by the second universal regression rotary design, 1 / 2, a total of 32 plots.All the test arranged word, every 9 to 10 additional planting area of a conventional control.The ground fertility uniformity, the former crop is oats, 0 ~ 30cm soil nutrients: 1.771 %, N0.107%, P2O550.150%, K2O1.976%, N115 × 10 -6, P_2O_510.0 × 10 -6, effective K_2O
