2010年晚季,广东省农科院水稻研究所和省农机推广站人员在省水稻所白云试验基地以常规超级稻品种合美占为试材,对机械插秧相关高产配套技术——壮秧、插植密度、插植深度和插植苗数进行了研究。结果表明:①机插秧苗在移植前3～4d喷施福戈(每亩秧地16g兑水30kg)后,秧苗较均匀、较粗壮、根系较发达,秧苗素质得到明显改善,有利于移植后早生快发。②在高地力、土层深厚的稻田,插植深度为标准,插植苗数为中等苗量的条件下,插植密度30cm×(16～30)cm×11cm都适宜。③在高地力、土层深厚的稻田,插植密度为30cm×14cm,插植苗数为中等苗量的条件下,插植深度以标准深度为好。④在高地力、土层深厚的稻田,插植密度为30cm×14cm,插植深度为标准的条件下,对于常规品种插植苗数以少苗、中苗或多苗均可,考虑用种问题,以少苗和中等苗量为宜。
In the late 2010, the Rice Research Institute of Guangdong Academy of Agricultural Sciences and provincial agricultural extension station personnel in the provincial Baiyun Baiyun test base to the conventional super-breed varieties together the United States as a test material, mechanical transplanting related high-yielding supporting technology - strong seedling, The planting density, planting depth and number of seedlings were studied. The results showed that: (1) Machine-borne rice seedlings were sprayed with Fogo 3 ~ 4 days before transplanting (30g per mu of seedling land and watered 30kg), the seedlings were more uniform and thicker, the root system was more developed, the quality of the seedlings was significantly improved, hair. ② In the high fertility, deep soil layer, planting depth as a standard, the number of seedlings planted medium seedling conditions, planting density 30cm × (16 ~ 30) cm × 11cm are appropriate. ③ In the high fertility, deep soil layer paddy planting density of 30cm × 14cm, the number of planting seedlings for medium conditions, the depth of planting to the standard depth as well. ④ In the high fertility, deep soil layer paddy planting density of 30cm × 14cm, planting depth as a standard condition, the conventional varieties of seedlings planted with seedlings, medium seedlings or more seedlings may consider the problem of species , To young seedlings and medium seedlings appropriate.
