对脱毒马铃薯稻田春季高产栽培技术进行了正交试验，结果表明：不同栽培措施处理对产量的影响大小为种植密度＞ 多效唑喷施＞ 施肥量＞ 地膜覆盖＞ 施肥种类；产量随着种植密度和施肥量的增加而提高，喷施多效唑和地膜覆盖处理分别较对照增产８．５％ 和６．３％ ；在不同栽培处理组合中，以种植密度６０ｃｍ ×１６ｃｍ 、用地膜覆盖、施用三元复合肥、每公顷施全Ｎ１５３．０ ｋｇ、Ｐ２Ｏ５ ７２．０ｋｇ、Ｋ２Ｏ２２５．０ｋｇ、在初蕾期喷施多效唑处理组合的产量最高。
The orthogonal experiment was conducted on the high-yielding cultivation techniques of spring rice in virus-free potato. The results showed that the effects of different cultivation measures on the yield were: planting density> spraying with paclobutrazol> fertilization> mulching> fertilization; Spraying paclobutrazol and plastic film mulching treatments increased 8.5% and 6.3% respectively compared with the control. In different combinations of cultivation and treatment, the planting density was 60cm × 16cm, covered with mulching film and ternary composite Fertilizer, per hectare applied N153.0 kg, P2O5 72.0kg, K2O225.0kg, in the initial bud stage spraying paclobutrazol treatment combination of the highest yield.
