冀东河滩沙地、丘陵梯田面积较大,冬春多风沙,夏秋雨量集中。栽植条桑,防风固沙,护坝保坡,充分发挥综合效益的潜力很大。但是,多年来对于条桑管理粗放,产量和效益较低。为改变这一状况,经过两年的调查分析和试验对比,找出了限制条桑生长的关键因素:旱、薄、荒和过量采叶饲蚕与养条有矛盾。针对生态特点,作者研究组配了一套相应的园艺措施。 (一)深栽埋干:育苗培垄,深化主根;栽
Jidonghe beach sand, hilly terraces larger, more winter and spring sand, summer and autumn rainfall concentrated. Planting mulberry, wind and sand, protect the dam slope, give full play to the potential of a great potential for comprehensive benefits. However, for many years extensive management of the strip mulberry, yield and benefit is low. In order to change this situation, after two years of investigation, analysis and comparison, we found out the key factors that restrict the growth of mulberry: drought, thinning, shortage and over-harvesting of silkworm have a contradiction with feeding. In response to the ecological characteristics, the author’s research team matched a set of corresponding horticultural measures. (A) deep planting dry: Nursery ridge, deepening the main root; planted
