山东省临朐县九山镇自1993年起组织5名林果技术员对柴家庄流域3800亩板栗实施早期丰产技术开发,使其两年见果,三年丰产,且病虫害果显著减少,市场竞争力大为增强,实现了早产高产和优质高效。具体技术措施如下: 一、整地密植沿等高线开挖深0.8米、宽1.5米的水平沟,回填后整成水平梯田,施足基肥,改善立地条件。春季每亩选用二年生健壮实生苗40株,浅栽踏实、灌水覆膜,提高成活率。
Since 1993, Jiuyen Town, Lintao County, Shandong Province, has organized 5 fruit technicians to develop 3800 mu of chestnut in Chaijiazhuang watershed to implement early high yielding technology, which will result in two years of fruit yield and three years of high yield with significant reduction of pests and diseases and market competition Power greatly enhanced, to achieve high yield premature and high quality and efficiency. Specific technical measures are as follows: First, the close planting of land along the contour line excavation depth of 0.8 meters, 1.5 meters wide horizontal ditch, backfill into the level of terraced fields, Shizujifei to improve site conditions. Spring per acre selection of biennial robust seedlings 40, shallow ease practical, irrigation covered, improve survival rate.
