旱育保姆不同剂量拌种育秧对比试验初报

A comparison experiment of different dosages of dry-cultivation "nurse"

为筛选出旱育保姆拌种育秧的最佳用量,使用250g、300g、350g、400g、450g 5种不同剂量旱育保姆拌种剂进行水稻种子拌种育秧对比试验,在大田同等肥水管理的条件下,结果表明:每667m2用350g旱育保姆拌种1.25kg育秧的秧苗素质好,在假茎宽、单株总根数、单株白根数、单株鲜重、干重、分蘖率等方面表现出明显优势,能提高水稻产量,在水稻免耕抛秧栽培的育秧工作中值得大面积推广使用。

In order to select best dosage for applying the ＂nurse＂ for seedling cultivation,different dosages are used for comparison experiments in mixing rice seeds. In the same conditions ,the results show that ＂nurse＂ of 350g/667m2 mixed with 1.25kg seeds can have a strong seedlings,which repre- sent many obvious advantages in all aspects, can increase rice yield, so that it is worth to be extended in seedling cultivation of rice no-tillage and seedling broadcasting mode.
