不同育苗基质对水稻秧苗素质的影响

Effects of Different Seedling Mediums on Seedling Quality of Rice

壮苗培育对于水稻生产来说至关重要。在寒地特殊的生态环境下,由于苗床土取土量大、取土困难等,使苗床营养基质的研究成为旱育壮秧技术的关键环节。本试验研究结果表明,用"碳化稻壳+牛粪+营养土"作为苗床基质,更有利于提高水稻秧苗充实度和促进秧苗干物质积累,比"秸秆+牛粪+营养土"配方更适合作为苗床基质。

Vigorous seedling cultivation was critical for rice production. In the cold ecological environment, there were some difficulties for large amount use of seedbed soil. Therefore, some new seedbed nutrient mediums were studied. The results showed that compared with rice straw, the application of carbonized rice husk ＋ cow dung ＋ nutrition soil as seedbed matrixs was conducive to improve rice seedlings plumpness and promote seedling dry matter accumulation, and this formulation was more suitable than straw ＋ cow dung ＋ nutrition soil.
