摘要
[目的]为吉粳102的大面积推广提供科学依据。[方法]采用五因素二次回归正交旋转组合设计，研究5个因子（施氮量、施磷量、施钾量、播种密度和每穴苗数）及每个因子的5个水平对吉粳102产量的影响。[结果]各因素对吉粳102的作用表现为：施氮量〉施磷量〉密度〉每穴苗数≥施钾量。5个栽培因素与产量均呈明显的抛物线关系。施氮量对产量的效应最为明显。施氮量与每穴苗数呈负的交互作用。模拟结果表明，吉粳102的最高产量10896kg/hm^2。当吉粳102产量达到10500kg／hm^2时，要求施氮量为132～167kg／hn？，施磷量为87．113kg/hm^2，施钾量为51～98kg／hm2，移栽密度为30cm×（13．9～19．4）cm，每穴苗数为2～4棵。[结论]建立了吉粳102的高产栽培技术体系。
[Objective] The study aimed to provide the scientific basis for extension of Jijing 102 in large scale. [Method] The five factors quadratic regression orthogonal rotational combination design was taken to study the effects of 5 factors （N rate, P rate, K rate, sowing density and seedling number per hole） and 5 levels of each＇faeter on the yield of Jijing 102. [Result] The effects of each factor on Jijing 102 showed as N rate 〉 P rate 〉 sowing density 〉 seedling number per hole 〉 K rate. The relationship between 5 cultivation factors and yield all showed a parabola type. The effect of N late on yield was the most obvious. The N rate and seedling number per hole had a negative interaction. The simulated result showed that the highest yield of Jijing 102 was 10 896 kg/hm2. If the yield of Jijing 102 reached 10 500 kg/hm2, the N late of 132 - 167 kg/hm2, P rate of 87 - 113 kg/hm2, K rate of 51 - 98 kg/hm2, sowing density of 30 cm x （ 13.9 - 19.4） cm and seedling number per hole of 2 - 4 plants were required. [ Conclusion ] The technical system of high yielding cultivation for Jijing 102 was established.
