摘要
通过设置营养球、营养块、营养土撒播、直播4种高粱育苗方式试验,结果表明:营养球、营养块、营养土撒播、直播每667m2高粱实际平均产量分别为330.00kg、324.51kg、292.78kg和182.84kg。营养球、营养块、撒播每667m2高粱平均产量较直播(CK)增产80.5%、77.5%和60.1%。纯收益以营养块最高,为898.40元/667m2,其次为营养球,直播最低(465.40元/667m2)。净投产比以撒播最高(1∶6.19),其次为营养块,直播最低(1∶3.29)。综合4种育苗方式的产量、产值、纯收益、净投产比,营养块育苗是高粱理想的育苗移栽方式。
Four raising seedlings patterns （nutrition ball, nutrition piece, broadcast seeding with nutrition soil and direct seeding） were used to investigate effects of different raising seedlings on yield of sorghum. The results show that the average yields/ per 667m^2 with the nutrition ball, nutrition piece, broadcasting with nutrition soil and direct seeding are 330.00 kg, 324.51 kg, 292.78kg and 182.84kg respectively. The average yield with the nutrition ball, nutrition piece, broadcasting with nutrition soil are 80.5%, 77.5% and 60.1% higher than that with the direct seeding separately. The order of pure income is nutrition piece （ 898.40 yuan/667m^2 ）〉nutrition ball（ 866.60yuan/667m^2） ~broadcasting with nutrition soil（ 836.80 yuan/ 667m^2 ）〉direct seeding（465.40 yuan/667m^2） and the net ratio of cost： income is broadcasting with nutrition soil （1 ： 6.19）〉 nutrition piece（1 ： 5.02）〉nutrition ball（1 ： 3.78）〉direct seeding（1 ： 3.29）. The best pattern for raising sorghum seedlings is the nutrition piece among four tested raising seedlings pattern according to yield, output value, pure income and net ratio of cost ： income.
