板栗大多栽植在山坡、沟谷和丘陵地带,自然条件恶劣加上缺乏有效的管理措施,许多栗园都存在土壤有机质含量低的问题,进而导致板栗产量低.为此,我们在实践中总结了一套通过加强栗园土壤管理提高板栗产量的办法.1 建好水土保持工程1.1 建树坪对生长在地形复杂的地段的栗树或零散栗树,可以采用这种方式.建树坪可以根据当地条件,取石方便的地方应建立石坝树坪,取石不便或无石可取的地方可以建土坝树坪.(1)石坝树坪.于下坡面树冠投影内垒筑半圆形坝墙,垒前要打好地基.墙高度依地势而定,缓坡可低些,陡坡要高些,达到树下有一定的平面,并做到外高内低,拦蓄雨水.(2)土坝树坪.于下坡面树冠投影内筑半圆形土埂,从上坡面取土,土埂高度约40cm,并在上侧边缘留溢洪口,水过多时从溢洪口流出,以免冲坏埂沿.这种
Most of the chestnuts are planted in hillsides, valleys and hilly areas, with poor natural conditions and the lack of effective management measures, many chestnut farms have problems of low soil organic matter content and thus low chestnut yield. Therefore, we summarize in practice one Set of measures to improve chestnut yield through strengthening chestnut soil management.1 Soil and water conservation projects are to be completed 1.1 Jianshuping Chestnut trees or scattered chestnuts growing in areas with complex topography can be used in this way.The establishment of soil layers can be based on local conditions, Stone convenient for the place should be set up Shuping Ping, stone access inconvenience or no place desirable to build earth dam tree Ping. (1) Before laying a foundation, the height of the wall may depend on the topography, the gentle slope may be lower, the steep slope should be taller, and the plane below the ground must reach a certain level, and the outer height should be kept within reach and the rainwater should be reserved. In the downhill crown projection built semi-circular soil, from the upper slope to take soil, soil 埂 height of about 40cm, and in the upper edge of the spillway overflow, excessive flow from the spillway to avoid damage 埂Along this
