2014年6月-9月,针对水稻机插盘育秧土营养培肥的要求,采用蚕沙作为水稻盘育秧土的养分,进行水稻盘育秧试验。结果表明,水稻盘育秧土中添加蚕沙能有效的增强盘育秧苗素质。育秧土添加蚕沙显著增加了3叶1心期水稻秧苗叶片含水量、叶片叶绿素含量和根系活力,同时降低了叶片可溶性糖含量。试验提出水稻育秧土添加蚕沙的量以30g/盘较为适宜。
From June to September of 2014, according to the requirements of nutrition cultivation and fertilizing of rice seedlings for raising seedlings, silkworm excrement was used as the nutrient of paddy-seedling for paddy rice. The results showed that the addition of silkworm excrement to the paddy-seedling of rice could effectively enhance the quality of the seedling. The addition of silkworm excrement to the seedling soils increased the leaf water content, chlorophyll content and root vigor of the rice seedlings in three leaf and one heart phases, and decreased the content of soluble sugar in leaves. The experiment suggested that the amount of rice seedling excretion silkworm excrement to 30g / tray is more appropriate.
