不同有机物料对库尔勒香梨长势与产量的影响

Effect of Different Organic Materials on Growth and Yield of Korla Fragrant Pear

在田间条件下,设置不同有机物料(生物黑炭、羊粪)的施肥处理,对20a树龄的库尔勒香梨进行生育期树体长势与产量监测。结果表明,4—10月为香梨生长期,夏季(5月5日至8月7日)为香梨枝干生长最快时期,嫁接基径、树高、新梢直径和长度的增长量最大;春季(4月1日至5月5日)为香梨叶片生长最快时期,叶片厚度、叶绿素含量及叶面积指数增长量也最大;施用有机物料可以促进香梨树体生长和提高产量,而且随着有机物料施入量的增加其效果越显著。羊粪施肥效应大于生物黑炭。

Different treatments of fertilization with organic materials（biological black carbon and sheep excre ment） in field are set and the growth and yield of 20 year Korla fragrant pear in growth period are monitored. Results show that the annual growth cycle of Pyrus sinkiangensis tree is between April and October, the branch growth of Pyrus sinkiangensis tree is the fastest in summer（from May 5 to August 7）, and the incre ments of grafting basal diameter, tree height, and shoots diameter and length are the largest. The growth of leaves is the fastest in spring （from April 1 to May 5） and the increments of leaf thickness, Chl content and LAI are the largest too. Application of organic materials in soil can promote the growth and improve the yield of Korla fragrant pear, but also its effects are more obvious with organic materials increasing. The effects of fertilization are showed as the order of sheep excrement biological black carbon.
