苹果园土壤分层管理局部优化节水节肥养根壮树技术

Local optimization technology of soil stratification management in apple orchard to save water and fertilizer and promote tree vigor via rearing root

苹果园土壤分层管理局部优化节水节肥养根壮树技术,是结合苹果根系功能特性,采取表层覆盖、中层微补、下层贮水,建立局部稳定、适宜根系生长的优良环境,实现节水节肥和养根壮树的目标。本技术以自然降水为主,微补载体蓄水,局部优化根际环境,调控根系结构,平衡养分分配,减少冗余消耗,提高叶片质量和树体贮藏营养水平,是苹果增产提质的一项实用技术。可节水80%,节肥40%以上,提高产量20%。

We have developed an apple orehard management technology on local optimization of soil stratification management to promote tree vigor via rearing root and reduce the usage of water and fertilizer. This technology builds a locally stable and suitable environment with top layer cover, middle layer microscale supplement and base layer water-store to rear root and promote tree growth using less water and fertilizer. It uses natural water with the supplement of special carrier retaining water to support tree growth. Application of this technology locally optimizes the rhizosphere environment, controls the root structure, balances the nutrient distribution, reduces the consumption, improves the leaf quality and nutrition storage level, and finally increases the output and improves the fruit quality. Statistical analysis indicated that this technology could increase the production by 20% with 80% less water and 40% less fertilizer usage.
