我校研制出的ZZPY系列水稻抛秧机，生产效率是人工抛秧和机械插秧的4—6倍，是人工插秧的20多倍；抛栽均匀度变异系数小于15％；亩作业成本降低30％，亩产量可提高10％一20％，最高的可达28％。在试验推广中，许多用户都是初次使用该种机器，但都能在效率和收益上取得好的结果 The ZZPY series rice transplanter developed by our school has a production efficiency of 4-6 times that of artificial seedling throwing and mechanical seedling transplanting and is more than 20 times of manual transplanting. The variation coefficient of throwing uniformity is less than 15% and the operating cost of mu is reduced by 30% %, Yield per mu can be increased by 10% to 20%, the highest up to 28%. In the pilot promotion, many users are the first time using this kind of machine, but can achieve good results in terms of efficiency and profitability
