Several Factors Influencing Seedling Establishment of No - tillage Seedling Broadcasting Cultivation of Early - season Hybrid Rice

摘要

The effects of four different factors on techniques for seedling establishment of No - tillage seedling broadcasting cultivation of early - season hybrid rice were studied. The results showed that no - tillage seedling broadcasting cultivation was beneficial to root standing, seedling establishment, earlier and faster growth and promoted plant growth under the condition of appropriately low water level (around 1 cm), short age seedling and appropriate increase of N application at early growth stage. The speed of seedling establishment of no - direct seedling have great relation to long or short age seedling, the short age seedling was beneficial to the acceleration of the seedling establishment process and promotion the rice growth.
