Matched cultivation method preventing stagnant water in upper soil for planting citrus in rice field

Abstract

The invention relates to the field of matched cultivation methods preventing stagnant water in upper soil for planting citrus in a rice field, and discloses a wide-bed deep-ditch earthing-up ridging method. The plow pan of the rice field is broken during ridging, the characteristic that the plow pan is hard and retains water is overcome, and the purpose of preventing stagnant water in upper soil for planting citrus in the rice field is achieved; ditches (2) are backfilled with a backfill surface oil layer, a modified soil material layer and a backfill soil layer from bottom to top, and the purpose of making soil fertile is achieved; a surface soil stripping technology is utilized to apply stripped surface soil to land reclamation, loss or waste of the earth surface mellow soil source is effectively prevented, and soil fertility is maintained; drainage channels (1) are dug to form a smooth drainage network, and stagnant water is rapidly drained; field planting points (7) are determinedaccording to the plant and row spacing of 2 meters*5 meters. The method has the advantages of simple soil preparation structure arrangement, convenient implementation and good early fruiting and highyield effect.

Description

technical field [0001] The invention relates to the technical field of citrus planting, in particular to a matching cultivation method for replanting citrus in a paddy field to prevent water stagnation in the upper part of the soil. Background technique [0002] Paddy soil is an artificial soil formed by long-term hydroponic cultivation. Due to periodic oxidation-reduction alternation and leaching deposition, several new layers can be formed on the basis of the original parent soil, including the surface soil layer (cultivation layer), plow bottom layer, Redox layer (bleaching layer, retention layer, depotential layer, latent layer, etc.), parent material layer, etc. Due to the need for a certain water layer during the growth of rice, the bottom layer is plowed in the soil profile, which is compact, sticky and dense, and is formed by long-term hydroponic irrigation. [0003] When the paddy fields are converted into citrus orchards, because the paddy fields have been flooded...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the complex structure layout problem of paddy fields replanted with citrus in the prior art, and provide a supporting cultivation method for replanting citrus in paddy fields to prevent water stagnation in the upper part of the soil. The supporting cultivation method has the advantages of simple structure and layout of site preparation, convenient construction, good effect of early knot and high yield, soil fertilizer and fertilizer preservation
