淮糯12田间品比试验表现及高产栽培技术探讨

【目的】探讨淮糯12田间综合表现和高产栽培技术。【方法】以皖稻68为对照品种，采用单本和双本栽插方式，研究不同栽插方式对淮糯12经济性状、抗性和产量的影响，并总结了其高产栽培技术。【结果】采用双本栽插，淮糯12穗数较皖稻68少18．0万／hm^2，穗实粒数较皖稻68多18．5粒，平均产量为8655．0kg／hm^2，较单本栽插增产20．2％，较双本栽插的皖稻68增产10．6％。田间表现抗白叶枯病，抗穗颈瘟，中感纹枯病，高抗条纹叶枯病。栽培上要注意培育壮秧、合理密植、配方施肥和病虫草害防治。【结论】淮糯12产量高、抗病性较好，分蘖力较弱，适宜双本栽插．

Comparison Experiment and High Yield Cultivation Techniques of Huainuo 12

[Objective] The paper aimed to discuss field performance and high yield cultural techniques of Huainuo 12. [Method] With Wandao 68 as control, two cultivation methods with transplanted by single plant and planting two seedlings were used to study the effects of different cultivation methods on economic character, resistance and yield of Huainuo 12, High yield cultural techniques were also summarized. [Result] With planting two seedlings, compared to the control spike number of Huainno 12 decreased 18.0×104/hm^2 and grain numbers per ear increased 18.5 grains per spike. The average yield was 8 655.0 kg/hm^2, increased by 20.2% than transplanted by single plant and by 10.6% than Wandao 68 with planting two seedlings. Huainuo 12 were resistant to bacterial blight and panicle blast and showed high resistance to rice stripe disease and medium susceptible to sheath blight. Summarized the main high yield cultivating measures of raising strong seedlings, rational close planting, formula fertilization and protection of plant diseases and insect pests. [Conclusion] Huainuo 12 with characteristic of high yield, strong resistance and lower tillering ability were suitable planting two seedlings.
