摘要
舜达 135 是绍兴市舜达种业有限公司与中国水稻研究所联合育成的早熟常规早籼稻新品种.为充分发挥该品种早熟、高产优势,在特早栽培条件下(播种期比绍兴传统播期提早 10～15 d)开展了不同梯度机插密度和肥料用量对比试验.结果表明,不同机插密度对舜达 135 有效穗数和产量有极显著影响,对穗粒数和结实率影响未达到显著水平;不同氮肥水平和氮肥水平与机插密度的互作对舜达 135 有效穗数、穗粒数、结实率和产量的影响均不显著;以种植密度 25 cm×14 cm、纯氮施用量 150 kg/hm2 的处理实际产量最高,达 9 633.45 kg/hm2.在 2021 年和 2022年示范中,特早栽培条件下舜达 135 百亩示范方产量分别达到 10 563.00 kg/hm2 和 10 258.05 kg/hm2.通过 2 年的示范,总结提出了舜达 135 特早栽培高产技术.
Abstract
s:Shunda 135 is a new early maturing conventional early indica rice variety bred by Shaoxing Shunda Seed Industry Co.,Ltd.and China National Rice Research Institute.In order to fully utilize the advantages of early maturity and high yield of Shunda 135,a comparative experiment was conducted on different planting densities and fertilizer amounts under special early cultivation conditions(the sowing date is 10-15 days earlier than the traditional sowing date in Shaoxing).The results showed that planting density had a highly significant impact on the number of effective panicles and yield of Shunda 135,but the impact on the number of grains per panicle and seed setting rate did not reach a significant level.The effects of different nitrogen fertilizer levels and the interaction between nitrogen fertilizer levels and planting density on the effective panicle number,grain number per panicle,seed setting rate,and yield of Shunda 135 were not significant.The treatment with a planting density of 25 cm×14 cm and pure nitrogen application rate of 150 kg/hm2 had the highest actural yield,reaching 9 633.45 kg/hm2.In the demonstration in 2021 and 2022,under special early cultivation conditions,the yield of Shunda135 in large-scale demonstration square reached 10 563.00 kg/hm2 and 10 258.05 kg/hm2,respectively.Through two years of demonstration,the special early cultivation techniques for high yield of Shunda 135 have been summarized.
