Ecological field effect based regeneration method for shelterbelt networks in plain farmlands

Abstract

The invention discloses an ecological field effect based regeneration method for shelterbelt networks in plain farmlands. Poplar trees are planted to form shelterbelts. A half-belt regeneration and/or in-belt regeneration way is adopted. Half-belt generation includes: a plurality of rows of trees on one side of one old shelterbelt are felled; a half belt remains; and a new shelterbelt is built in the felled half belt. In-belt regeneration includes: regeneration is performed among tree rows of one original shelterbelt or on the open space with trees felled; and shelterbelt regeneration is performed every three other years. The in-belt generation way is applicable to regeneration of ditch-road alternating type wide shelterbelts. The network in the plain farmlands regenerated by in-belt generation has good wind-breaking efficacy and also has a good ecological climate field effect. The ecological field effect based regeneration method for shelterbelt networks is important for scientific regeneration and reformation of the existing farmland shelterbelt networks, promotion on regeneration and healthy growth of the farmland shelterbelt networks, increase of regeneration quality and management level of the shelterbelt networks, and realization of continuity and stability of protective efficacy and comprehensive benefits of the shelterbelt networks.

Description

technical field [0001] The invention relates to a method for maintaining farmland forest networks, in particular to a method for maintaining high-standard farmland forest networks in plain areas. Background technique [0002] Farmland forest network is an important part of the farmland shelterbelt system in plain agricultural areas. It plays an important role in improving farmland microclimate, soil, hydrology and other conditions, resisting natural disasters, ensuring stable and high yields of agriculture and animal husbandry, and providing various forest by-products. However, due to the problems of excessive tree age, growth decline, single tree species, poor structure, aging species, and serious pests and diseases in the existing farmland forest network in the plain area, especially the lack of scientific and quantitative determination of its regeneration method and thinning age, serious problems Affect the overall protection efficiency of high-standard forest network and...
