Embodiment 1

[0033] A method for improving compacted soil for flue-cured tobacco planting, comprising the following steps:

[0034] (1) Flue-cured tobacco planting: ridges in the field, ridge height 25cm, ridge bottom width 90cm, ridge top width 35cm, ridge distance 100cm, 1000kg / mu of rice husks and 1000kg / mu of humic acid original powder were buried in the ridges and furrows, and the tobacco The seedlings are transplanted to the ridge, and after transplanting, the ridge surface and the ridge and furrow are covered with plastic film, and the ridge surface plastic film is removed when the tobacco grows to the cluster stage;

[0035] (2) Rice planting: after the tobacco is harvested, the ridges are re-raised, the ridge height is 25cm, the ridge surface width is 75cm, and the ridge distance is 40cm, and 2000kg / mu of tobacco straw is buried in the ridge and furrow, and irrigation treatment is carried out after filling, and the irrigation depth is lower than The ridge surface is 3cm, and the r...

Embodiment 2

[0047] A method for improving compacted soil for flue-cured tobacco planting, comprising the following steps:

[0048] (1) Flue-cured tobacco planting: ridges are raised in the field, ridge height is 30cm, ridge bottom width is 95cm, ridge top width is 35cm, ridge spacing is 110cm, and 1500kg / mu of rice husks and 750kg / mu of humic acid former powder are buried in the ridge and ditch. The seedlings are transplanted to the ridge, and after transplanting, the ridge surface and the ridge and furrow are covered with plastic film, and the ridge surface plastic film is removed when the tobacco grows to the cluster stage;

[0049] (2) Rice planting: after the tobacco is harvested, ridges are re-raised, the ridge height is 30cm, the ridge surface width is 80cm, and the ridge distance is 45cm, and 1500kg / mu of tobacco straw is buried in the ridges and furrows. After filling, irrigation treatment is carried out, and the irrigation depth is lower than The ridge surface is 4cm, and the rice ...

Embodiment 3

[0061] A method for improving compacted soil for flue-cured tobacco planting, comprising the following steps:

[0062] (1) Flue-cured tobacco planting: ridges in the field, ridge height 30cm, ridge bottom width 100cm, ridge top width 40cm, ridge distance 120cm, 2000kg / mu of rice husks and 500kg / mu of humic acid original powder were buried in the ridge and furrow, and the tobacco The seedlings are transplanted to the ridge, and after transplanting, the ridge surface and the ridge and furrow are covered with plastic film, and the ridge surface plastic film is removed when the tobacco grows to the cluster stage;

Abstract

The invention relates to the technical field of soil improvement, in particular to a method for improving hardened tobacco planting soil. The method includes the steps of firstly, planting tobacco; secondly, planting paddy rice; thirdly, applying materials and performing smoldering, to be more specific, furrowing the field after paddy rice harvesting, sequentially filling paddy rice straw, soil particles, paddy rice straw, the mixture of tobacco straw and rice hulls, soil particles, rice hulls and soil particles into furrows in a layered manner, and performing smoldering after the materials are applied, wherein the thickness of each layer is different; fourthly, finishing the soil. By the method, soil bulk density can be lowered evidently, soil total porosity and ventilation porosity can be increased, soil organic matter and total nitrogen content can be increased, the activity of soil microorganisms can be increased, the hardening condition of the tobacco planting soil can be improved, and soil permeability can be evidently increased.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for improving the compacted soil of flue-cured tobacco planting. Background technique [0002] Flue-cured tobacco is one of the important economic crops in my country and occupies an important position in the national economy. Due to the large number of people and few land in my country, the situation of food and tobacco land competition is severe, the land in flue-cured tobacco planting areas is highly intensively utilized and the multiple cropping index is high. Decrease, the organic matter content continues to decrease, and the problem of soil compaction for tobacco planting is becoming more and more serious. SUMMARY OF THE INVENTION [0003] In view of the above technical problems, the purpose of the present invention is to provide a method for improving the soil compaction of flue-cured tobacco planting, so as to solve the increasingly serious problem of ...
