The invention relates to the technical field of
ecological agriculture. The invention provides an
orchard full life cycle ecological and production function collaborative improvement method, which takes a ratio of a
fruit tree trunk ground
diameter to an adult target ground
diameter as a core quantitative index, introduces an individual development threshold and a
group transformation threshold to construct a statistical
decision model, and judges whether the whole
orchard is in a
young forest stage or a forest stage. Secondly, according to the core contradiction between
ecology and production in different stages, functional complementary herbal communities are configured, and deep, straight and thick-root herbal communities are planted in the
young forest stage to rapidly cover the
earth surface and improve deep soil; in the forest establishment period, shallow and dense fine-
root type herbs are replaced, and biological
nitrogen fixation and surface soil maintenance are promoted. Different farming schemes such as
cutting coverage and water and
fertilizer management are implemented in different stages. According to the method, management measures in the
orchard establishment period, the
young forest period and the forest establishment period are organically connected in series, a full-life-cycle closed-loop technical
system is formed, the development of orchard management from extensive experience to dynamic precision is realized, and the core contradiction between
ecology and production in each stage is solved.
