摘  要：
[目的]探讨育秧基质在机插双季晚稻上的应用效果。[方法]以"上农粳2号"为试验材料,通过田间试验,研究育秧基质对机插双季晚稻秧苗素质、农艺性状以及产量形成要素的影响。[结果]1/2基质+1/2营养土处理在生育期、主要农艺性状上与全营养土处理和全育秧基质处理相差不大,在实际产量上,呈现1/2基质+1/2营养土处理>全育秧基质处理>全营养土处理的趋势;秧苗期针对1/2基质+1/2营养土处理采取多效唑化控,可以显著控制该处理的植株高度,达到该地区毯状机插较为理想的栽插植株高度(17.7cm),同时还可以增加植株根系长度,提高植株栽插质量。全营养土处理在控制秧苗茎基宽和根系盘结力上效果最佳。[结论]毯状机插双季晚稻育秧时,采取一半基质一半营养土制成混合育秧基质效果最优,不仅可提高产量,而且还可有效减少育秧成本,可作为当地双季晚稻毯状机插秧推广的模式。

摘  要：
[Objective] To research the effects of seedling raising substrate on the double-cropping late rice.[Method] With Shangnongjing No.2 as the test materials,field test was carried out to research the effects of seedling raising substrate on the seedling quality,agronomic characters and yield formation elements.[Conclusion]1 /2 substrate + 1 /2 nutrient soil treatment had slight differences in growth period and main agronomic character with total nutrient soil treatment and total seedling raising substrate treatment.In actual output,we had 1 /2 substrate + 1 /2nutrient soil treatment > total seedling raising substrate treatment > total nutrient soil treatment.In seedling stage,paclobutrazol chemical control in 1 /2 substrate + 1 /2 nutrient soil treatment could significantly control the plant height,so as to reach the idea transplanted plant height(17.7cm).At the same time,the root system length could be enhanced so as to improve the machine-transplanted quantity of plant.Total nutrient soil treatment had the optimal effects on controlling the seedling stem base width and root winding force.[Conclusion]During blanket-type mechanical transplanting double-cropping late rice,1 /2 substrate and 1 /2 nutrient soil are prepared to the optimal mixed seedling raising substrate,which can enhance the yield,effectively reduce the seedling raising cost,and be used as the extension mode of blanket-type mechanical transplanting double-cropping late rice in Anhui Province.
