This technology was that the holes for transplanting in well cellar were made with dedicated tools for making well cellar, and the seedlings were placed into the well cellar vertically during transplanting. This new technology integrates heat preservation, management of rising temperature, early transplanting and deep planting. Results showed that the technology of transplanting in well cellar improved the growing environment of crops after transplanting through elevation of temperature and heat preservation, and tempered the dramatic change in the temperatures encountered by transplanted seedlings. This technology significantly reduced labor force requirement by 98.06%, 58.96% and 64.44% in tobacco, maize and pepper, respectively. Transplanting in well cellar without mulching film further lowered the labor force requirement, with decrease by 121.77% and 115.40% in maize and pepper, respectively. In addition, this technology significantly promoted crop growth, reduced the time until marketing for maize and pepper by 11 d and 6 d, respectively, and increased economic benefits by 67.03% and 44.24%, respectively. Thus, the technology of transplanting in well cellar showed strong promise for improving upon existing technologies to provide greater economic returns, particularly in areas where labor force shortage threatens to hamper agricultural production.展开更多
