摘要
为探索适宜长沙双季稻区机抛秧的育秧基质,以'锦两优 128'为试验品种,研究了 8 种不同水稻育秧基质对早稻秧苗素质、田间长势和产量效益的影响.结果表明:以碳化稻壳灰和营养土配比的育秧基质培育的秧苗出苗率和成秧率高、叶绿素含量高、地上部形态、地下部形态、分蘖能力均较好,且成本较低,产量表现优;其中,60%营养土+40%碳化稻壳灰处理培育的秧苗产量效益最高,适宜在长沙双季稻区机械抛秧推广应用.
Abstract
This study aims to explore the suitable matrix for cultivating rice seedlings for machine throwing in the double cropping rice production area of Changsha.The seedlings of'Jinliangyou 128'were cultivated with eight different matrixes,and the quality,field growth,and yield performance of early rice seedlings were studied.The results showed that the seedlings cultivated with the matrix composed of carbonized rice husk ash and nutrient soil had high seedling emergence rate,seedling formation rate,and chlorophyll content,good aboveground and underground morphology,and strong tillering ability.Moreover,the seedlings were cultivated with low costs and high yield performance.Among the treatments,60%nutrient soil + 40%carbonized rice husk ash had the highest yield performance of seedlings,being suitable for the promotion and application in the cultivation of rice seedlings for mechanical throwing in the double cropping rice production area of Changsha.
