水田覆膜直播压槽与覆盖物对水稻出苗的影响OA北大核心CSTPCD
Effects of Film Mulching Direct Seeding Groove and Mulch on Emergence of Rice
为探讨水田覆膜直播压槽与覆盖物对土壤温度、出苗率及秧苗素质的影响,以籼型常规水稻中早39为材料,进行了池栽模拟试验.结果表明,膜上压槽及覆盖能提高土壤温度、缩短出苗时间;在体积较大的覆盖物中加入一定基质有利于提高秧苗素质和干物质积累;在体积较小的覆盖物中加入基质对秧苗素质影响不大.本研究中,条播条件下,每1 m覆盖205.9 mL细沙的处理出苗齐、快,秧苗更壮.
A pond planting simulation experiment was conducted to explore the effects of film mulching direct seeding groove and different volume of mulch on soil temperature,seedling emergence rate and seedling quality,using indica conventional rice Zhongzao 39 as the test material.The results showed that the groove on the film and mulching increased the soil temperature and shorten the emergence time.Adding a certain amount of substrate coverage to the larger coverage improved seedling quality and dry matter accumulation.In the smaller coverage,the addition of the substrate had little effect on seedling quality.Under drill seeding conditions,the treatment of covering 205.9 mL of fine sand per 1 m resulted in uniform,faster of seedling emergence,and seedlings were stronger.
