试验采用四元二次旋转回归正交组合设计,研究脱毒马铃薯品种大西洋种植蜜度、肥料种类及施用量与产量之间的优化数学模型,经计算机对模型进行分析模拟,求得脱毒马铃薯原原种大西洋每公顷产量在18 826.5kg以上的组合方案有266个,建立高产栽培技术模型:种植密度为每公顷129 450～133 680株,每公顷纯(N)施用量为109.8～123.75 kg,纯(P2O5)施用量为237.9～260.1 kg,纯(K2O)施用量为254.25～294.3 kg。措施中心值是:每公顷种植密度为131 655株、施纯N 117 kg、P2O5 249 kg、K2O 274.5 kg。N、P2O5、K2O的比例约为1:2.1:2.4。
The quadratic quadratic quadratic regression model was used to study the optimal mathematic model of honey planting degree, fertilizer type, application rate and yield of the detached potato variety Atlantic. The model was analyzed by computer to simulate the virus-free potato There are 266 combination programs of the original original Atlantic per hectare yielding more than 18 826.5kg. The high-yielding cultivation technology model was established: the planting density was 129 450-133 680 per hectare, and the application rate of pure N per hectare was 109.8-123.75 kg , Pure (P2O5) application rate of 237.9 ~ 260.1 kg, pure (K2O) application rate of 254.25 ~ 294.3 kg. The center values for the measures are: planting density of 131 655 plants per hectare, applying N 117 kg, P2O5 249 kg and K2O 274.5 kg. N, P2O5, K2O ratio of about 1: 2.1: 2.4.
