摘要
以谷丰A和闽恢3301为试验材料,比较了不育系谷丰A在直播和育秧移栽两种制种方式下生育期、育性、产量及其构成因素方面的差异。结果表明,直播较移栽生育期缩短3 d左右,花期更加集中,午前花率、柱头外露率和异交结实率等均显著提升,最高苗数、有效穗数和结实率等农业性状也得到较大提升,制种产量表现突出,与育秧移栽制种方式相比增产达5.76%。谷丰A直播制种可节约成本,增加制种产量,提高制种效益,每hm2增收达6786元,增收10.17%。
In this research,Gufeng A and Minhui 3301 were used as experimental materials to compare the differences in growth period,fertility,yield and yield components of sterile line Gufeng A under the two cultivation methods of direct seeding and seedling transplanting.The results showed that,compared with the transplanting method,the seed production period of direct seeding method was shortened by about 3 days,and the flowering period was more concentrated.The flowering rate,stigma exsertion rate and outcrossing rate before noon were significantly improved;the maximum number of seedlings,effective panicle and seed setting rate,agricultural traits were also greatly improved,and the yield increased by 5.76%.The income per hectare is up to 6,786 yuan,which was increased by 10.17%.
