研究了‘沪紫黑糯1号’不同种植方式(直播、育苗移栽、地膜覆盖)和种植密度(45 000、52 500、60 000、67 500、75 000株/hm2)时的农艺性状、产量和经济性状表现。结果表明:不同种植方式下‘沪紫黑糯1号’在产量方面差异显著,相同播期下地膜覆盖产量最高为13 986kg/hm2,熟期比其他种植方式早2d,最佳种植模式为地膜覆盖。不同种植密度下‘沪紫黑糯1号’在产量、茎粗、单株重、单株茎叶重、穗行数、穗粗方面差异显著,适宜种植密度为52 500～60 000株/hm2。
The agronomic characters of ’Huzhai No.1’ with different planting modes (direct seeding, seedling transplanting, plastic film mulching) and planting densities (45 000, 52 500, 60 000, 67 500, 75 000 plants / hm 2) Yield and economic traits. The results showed that ’Huzhehenuo 1’ had significant difference in yield under the different planting modes. The highest yield of mulching film was 13 986kg / hm2 under the same sowing date, and maturity was 2 days earlier than other planting methods. The best planting pattern was mulching cover. Under different planting densities, ’Hu Zi He Nuo 1’ showed significant differences in yield, stem diameter, single plant weight, stem and leaf weight per plant, ear number and ear diameter. The suitable planting density was 52 500 ~ 60 000 plants / hm 2 .
