摘　　要：Mechanized transplanting technology for rice sedligs growing in molded-hole pre-nursery tray made of rice straw,successfully developed by the research team led by principal scientist Prof.Wang Chun from Heilongjiang Bayi Agricultural University after five years'systematical investigation and field experiment,is given credit for a technological revolution of rice production integrating agricultural machinery and agronomy,owning complete proprietary intellectual property rights.In order to popularize this rice-growing technology.concave rice pre-nursery tray made of rice straw was originated,precision seeding process and equipment were invented,the transplanting mechanism of the corresponding matched rice transplanter was improved,and the technology-adapted high-yield rice variety and agronomy were also perfected.The key agronomic requirements of this rice growing technology include early-stage rice seedling nursery,colling of rice seedling roots,uniform and strong rice seedlings,rice transplanting without injuring the root system,prolonging the effective growth period without seedling rejuvenation stage,transplanting rice seedlings with uniform inter-rows and intra-rows.
