| The key technique, technology index, theoretic foundation of yield increase of Maize Cellular Planting Technique was studied and discussed.The results indicate: The mass yields are dependent on the nutrition situation of maize single plant;to increase density by reducing row space not only is good for “enough density” but also keeps nutrition area of maize single plant suitable for “strong single plant” under “enough density” this technique has significant high yield effect.The result of yield determination by experiment and extension in production shows that the Maize Cellular Planting Technique is good for single maize plant to absorb sunlight equally under “enough density”, and get high density and it possesses the advantage of close-planting, nutrition improvement, increasing yield and benefit and will be used widely in the future. |
