摘要
[目的]探讨浙粳88的高产机插栽培技术。[方法]提出浙粳88机插栽培的目标产量与构成,从育秧技术、大田管理技术和适时收获3个方面详细介绍其高产栽培技术。[结果]浙粳88(浙审稻2011008)是由浙江省农业科学院作物与核技术利用研究所选育而成的中熟高产粳稻新品种,2011年2月通过审定。生产表现为高产稳产、米质较优、抗性较强、生育期适中、青秆黄熟。10 500 kg/hm2产量结构为:有效穗330万~360万穗/hm2,每穗总粒135~140粒,结实率90%左右,千粒重26 g。浙粳88高产机插栽培技术中,育秧技术包括5个方面,分别为药剂浸种、控制虫传病害,催芽机催芽、确保整齐露白,整平秧板、确保秧苗平衡生长,精细播种、做到定量匀播,苗床管理;大田管理技术包括7个方面,分别为整平大田、短龄早栽、少本稀植、前氮后移、科学管水(浅水促蘖、及早搁田、薄水养胎、防止早衰)、病虫草害防治、喷施"爱苗"和"拿敌稳"等防病保健药剂。[结论]浙粳88机插生产技术可概括为基质育秧培育壮苗、短龄早栽小苗机插、科学管水防止早衰、统防统治适时收获。该技术可为浙粳88大面积推广应用提供科学指导。
[Objective] To discuss Zhejing 88 high yield machinery transplanting cultivation technique.[Method] The object and composition of Zhejing 88 was put forward,the high yield cultivation technique was introduced in details from three aspects of nursery technology,field management technology and timely harvesting.[Result] Zhejing 88 is a new variety bred by Crop and Nuclear Technology Utilization Institute of Zhejiang Academy of Agricultural Sciences,and approved in Feb.2011,with the production performance of high and stable yield,high quality,strong resistance,moderate growth period.10 500 kg/hm2 yield structure is: effective panicle 3.30-3.60 million spike/hm2,135-140 total grain per spike,seed setting rate about 90%,1 000-grain weight 26 g.The breeding technique includes: seeds soaking with medicaments to control insects and diseases,accelerating seed germination,flattening seedling plate,quantitative uniform sowing,seedbed management;field management technique includes seven aspects.[Conclusion] Zhejing 88 machinery transplanting technique includes matrix seedling,short age early transplanting seedling,scientific water management and senescence prevention,timely harvesting,the technique will provide scientific guidance for expanding application of Zhejiang 88.
