Embodiment 1

[0031] A paddy field soil improvement method of tobacco-rice rotation system, is characterized in that it comprises the steps:

[0032] 1) After all the tobacco leaves are harvested, the compound fertilizer that promotes the decomposition of the tobacco stems is evenly spread into the field when planting the late rice after planting the tobacco, and is fully mixed with the soil and the tobacco stems through the rotary tiller. The compound fertilizer components are dolomite powder and quicklime, and the dosage per mu is 30 kg. Among them, dolomite powder is 15 kg / mu (accounting for 50%), and quicklime is 15 kg / mu (accounting for 50%).

[0033] 2) After the step 1) is finished, the compound fertilizer for improving the tobacco-rice rotation field soil is evenly applied to the farmland, and is fully mixed with the soil when leveling the ground before transplanting. The compound fertilizer components are dolomite powder, urea, potassium nitrate and Bacillus subtilis, and the dosa...

Abstract

The invention provides a tobacco-rice crop rotation system rice field soil improvement method. The method comprises the following steps: tobacco stalks are cut into sections right in the field; a complex fertilizer promoting tobacco stalk decomposition is uniformly applied in the field; through land preparation of a rotary cultivator, the complex fertilizer promoting tobacco stalk decomposition is fully mixed with rice field soil and tobacco stalk sections; a complex fertilizer improving rice field soil is uniformly applied in the field; when the field is flattened, the complex fertilizer improving rice field soil is fully mixed with rice field soil. With the method provided by the invention, tobacco stalk decomposition speed and nutrient release rate are improved, such that soil nutrients are substantially improved. The rice field soil is improved, such that a technical support is provided for paddy rice high yield and high efficiency.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a paddy field soil improvement method of tobacco-rice rotation system. Background technique [0002] In my country's tobacco-rice rotation area, a large number of tobacco stems are produced after the flue-cured tobacco is harvested every season. Tobacco stalks returned to the field in dry land will cause serious diseases, but the tobacco-rice rotation has been treated with flooding in the rice season, and the diseases are relatively less. Therefore, the tobacco-rice rotation system has been promoted. The tobacco-rice rotation system refers to the cultivation system in which tobacco is planted first in the same paddy field and in the same year, and the land is prepared to plant a season of late rice immediately after harvesting the tobacco. At present, tobacco-rice rotation is an important flood-dry rotation system in southern my country, with a total planting area of ​​...
