摘要
为了水稻机械化旱田栽秧新技术的发展和推广应用,以津稻179为试材,研究水稻硬质和软质不同钵盘育秧对秧苗生长动态、秧苗素质的影响,以及起秧时钵体块含水量和硬度对机械化旱田栽秧成败的影响。结果表明:448穴的硬质钵盘育成的秧苗素质较好;起秧时钵体块含水量5%~10%、硬度2000~2500g内适合水稻机械化旱田栽秧。
In order to develop and popularize the new technology of transplanting rice seedlings with machinery in dry fields,the effects of bowls with different texture on seedling growth dynamics and quality were studied,as well as the effects of water content and hardness of bowl-tray block on the success of mechanized transplanting.The results showed that the quality of seedlings was better when seedlings were raised in 448-hole rigid POTS.The POTS blocks with water content as 5%~10%and hardness as 2000~2500 g were suitable for mechanized transplanting of rice seedlings in dry lands.
