板栗的初期营养生长对板栗的结实及个体发育影响很大。通过大量的实测资料进行分析 ,探讨华北花岗岩山地水土流失地区土地生产力的效益 ,对板栗的早实、丰产有着重要的意义。结果表明 :垫腐秸可使地径增粗37 2 % ,修盘扩穴可使地径增粗 2 8 8% ,枯秸覆盖可使地径增粗 2 6 1% ,平均单株比对照增产以处理 1为最高15 5 3% ,其次是处理 4为 114 7%。已达到提高板栗初期生长量及产量实验的目的。
The initial vegetative growth of chestnut has a great influence on the fruiting and individual development of chestnut. Through a large number of measured data to analyze the benefits of land productivity in granite mountainous areas in North China, it is of great significance to early fruiting and high yield of chestnut. The results showed that the soil thickening could be 37 2% thicker when the soil was matured, the ground diameter increased by 28.8% and the dry land covered by straw could increase the soil diameter by 26.1% The increase of production to treatment 1 is up to 15 5 3%, followed by treatment 4 to 114 7%. Has reached the initial growth of chestnut yield and yield the purpose of the experiment.
