The new cultivation models and profit analysis of oilseed rape
Six new cultivation models are tested in Hubei Province under uniform experiment design and with random sampling methodology. The models are transplanting in plowed paddy-field (TPP), direct seeding in plowed paddy-field (SPP),transplanting in untilled paddy-field (TUP), direct sowing in untilled paddy-field (SUP), relay transplanting in untilled cotton field (TUC), and relay sowing in untilled cotton field (SUC). And yield per unit area (YPA), yield per unit material input (YPM), yield per unit labor (YPL), and cost per kg rapeseed were used to review all these models. Results showed that direct seeding and no-tillage cultivation models characterized by simplicity with lower cost, higher efficiency and profit for saving working days.However, these simplified cultivation models are relatively of lower material utilization rate and lower unit area yield compared with the traditional model of transplanting.
