山地密植杏园高标准覆草,可收到培肥土壤、提高土壤含水量、促进浅根系发育、扩冠增产等多重效应。对13hm24～9年生杏树,5年覆草试验,较对照园每666.7m2平均增产202.5kg,单株平均冠积增大5.3m3,效益成本比高39.3％。
High density of mountain dense apricot orchard, can receive fertilizing soil, increase soil moisture, promote the development of shallow root system, crown expansion yield multiple effects. For 13hm24 ~ 9-year-old almond trees, the grass coverage of 5 years was increased by 202.5kg per 666.7m 2 in comparison with control garden, and the average crown plot per plant was increased by 5.3m 3, the benefit cost ratio was 39.3% higher.
