Embodiment 1

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

[0034] (1) Flue-cured tobacco planting: field ridges, ridge height 25cm, ridge bottom width 90cm, ridge top width 35cm, ridge distance 100cm, rice husk 1000kg / mu and humic acid powder 1000kg / mu are buried in the furrow, and the tobacco Transplant the seedlings to the ridge, cover the ridge surface and the furrow with plastic film after transplanting, and remove the plastic film on the ridge surface when the tobacco grows to the group stage;

[0035] (2) Rice planting: After harvesting the tobacco, ridges shall be raised again, with a height of 25cm, a width of 75cm, and a distance of 40cm. Tobacco stalks shall be buried in the furrows at a rate of 2000kg / mu. The ridge surface is 3cm, and the rice seedlings are transplanted to the ridge;

[0036] (3) Applying materials and smoldering: After the rice is harvested, ditch the field perpendicular to the planting direction of the rice. ...

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 hardened tobacco planting soil. 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 our country's large population and small land, the situation of grain and tobacco competition for land is severe, and the land in flue-cured tobacco planting areas is highly intensively used and the multiple cropping index is high. In production, there are still fertilization habits such as excessive chemical fertilizer application and low organic fertilizer application, which lead to poor soil quality. The content of organic matter keeps decreasing, and the problem of soil compaction in tobacco planting is becoming more and more serious. Contents of the invention [0003] In view of the above technical problems, the purpose of the present inventio...
