优质高产新品种武运粳30号机插高产栽培技术研究

[目的]探讨高产优质水稻新品种武运粳30号机插高产栽培技术,为其大面积推广应用提供科学依据。[方法]在总结2012、2013年试验的基础上,从提出高产技术指标、实施具体的栽培措施、试验结果3个方面进行分析,最终提出武运粳30号机插高产栽培技术。[结果]武运粳30号是2014年江苏省新审定的早熟晚粳新品种,具有穗型大、米饭食味品质优等特点。在麦茬或油菜茬中等偏上地力上,培育壮秧,高质量移栽;施纯氮292.5 kg/hm2左右,基蘖肥∶穗肥=5∶5;在有效分蘖临界叶龄期前1个叶位够苗,茎蘖数达到穗数的70%~80%时及时自然断水搁田,把拔节期高峰苗控制在345万~375万株/hm2,使茎蘖成穗率达75%以上。[结论]武运粳30号是一个极具产量潜力的大穗型早熟晚粳新品种,适宜在江苏省沿江和苏南地区中上等肥力条件下种植,从生育期来看,也同时适合安徽皖南和沿江地区种植。

Study on High Yield and Good Quality Cultivation Technology of a New Rice Variety Wuyunjing No.30 under Mechanical Transplanting

The aim was to discuss the high yield and good quality cultivation technology of a new rice variety Wuyunjing No. 30 under mechanical transplanting,and provide a scientific basis for its promotion and use in a large scale. [Method] Based on to sum up the tests of 2012 and 2013,the high yield cultivation technology of Wuyunjing No. 30 under mechanical transplanting were put forward from making high yield technological indices,carrying out the specific cultivation practics and test results. [Result]Wuyunjing No. 30 was a new early mature and late japonica rice,which was newly approved by Jiangsu Province in 2014,with the characteristics of big spike size and good quality. In the middle and upper soil fertilizer of wheat stubble or rapeseed stubble,to cultivate the strong rice seedlings,and to transplant by high quality; to apply pure nitrogen about 292. 5 kg /hm2,and the ratio of base fertilizer to spike fertilizer was5∶5; confirm on the enough seedlings one leaf positon before effective tillers critical leaf age,remove water timely when the tillers number accounted for 70%- 80% of spikes number,control the peak seedlings number at jointing stage 345 × 10^4- 375 × 10^4 plants /hm^2,then make the earbearing tiller percentage obtain over 75%. [Conclusion]Wuyunjing No. 30 is a new early mature and late japonica rice variety with big spike size and great yield potential,suitable for planting in the middle and upper soil fertilizer of along the Yangtze river of Jiangsu Province and southern Jiangsu Province,and suitable for planting in the south of Anhui Province and along the Yangtze river of Anhui Province at the same time from its growth period.
