Abstract:

Under the conditions of greenhouse in early spring in western Liaoning, the effects of different seedling raising matrix and seedling trays on seedling quality and yield of mechanical transplanting rice were studied, using Liaogeng 399 as the test variety. The results indicated that compared with using soil as seedling raising matrix, the other three kinds of seedling raising matrix could improve the quality of seedlings. Compared with CK（soil+ box tray）, the seedling quality of the other treatments were better, the transportation was more convenient, the damage of root system was light, and the time of seedling recovery after transplanting was shorter. The combination of M2K2（organic seedling raising matrix + pot blanket seedling tray） showed the best performance and the highest yield, the yield increased by 11.91% compared with CK.
