麻纤维膜在安徽省水稻育秧上的应用效果

Application Effect of Bast Fiber Film in Rice Seedling Raising in Anhui Province

2018—2020年在安徽省3个试验点开展麻纤维膜水稻育秧及机插秧技术的试验示范,结果表明:麻纤维膜水稻育秧可有效降低水稻育秧成本393.15~445.20元/hm^(2),减少机插秧漏插率2.1个百分点;同时,麻纤维膜育秧可促进秧苗根系发育,有壮苗盘结好的优势,机插后秧苗可早返青、早分蘖1~2d,增加水稻有效穗数10.02万穗/hm^(2),提高结实率2.62%,进而提高水稻产量6.034%,综合节本增效达到2001.00~2078.10元/hm^(2),社会经济效益良好。

Experiments and demonstrations in Anhui Province through the bast fiber film rice seedling raising and machine transplanting technology at three points in two years.The results showed that bast fiber film can effectively reduce the cost of rice seedling raising by 393.15~445.20 yuan/hm2,and the missed transplanting rate of machine transplanting can be reduced by 2.1%.At the same time,bast fiber film raising seedling can promote the develop⁃ment of root system,and has the advantage of strong seedlings and root intertwisting ability.After mechanical trans⁃planting,the seedlings can turn green and tiller 1~2 days earlier,increase the number of productive ears per mu of rice by 10.02×104 ears,increase the seed setting rate by 2.62%,increase the yield of rice by 6.034%,and the com⁃prehensive cost saving and efficiency increase reached 2001.00~2078.10yuan/hm2,which has achieved good social and economic benefits.
