Problems solved by technology

1) Long-term and large-scale application of lime will lead to soil compaction and nutrient imbalance, because lime only provides nutrient calcium, and a large amount of calcium will lead to soil magnesium and potassium deficiency and decrease in phosphorus availability; 2) Spreading of amendments, soil and The mixing process of the improver is labor-intensive and time-consuming, and it is prone to inhomogeneity, which may easily cause poor uniformity of soil pH adjustment; 3) There is a re-acidification process in the soil after the lime is applied, that is, the soil re-acidifies after the alkali consumption of the lime. Acidification occurs and is more acidified than before lime application

Embodiment 1

[0038] 1. Plot selection:

[0039] According to the division of ecological adaptability in the "China Tobacco Planting Regional Planning", the tobacco planting field was reasonably selected, and the test was arranged in the most suitable area - Guiyang County, Hunan Province; after collecting soil samples and testing, the soil pH was 4.7. The test area has supporting water sources and drip irrigation facilities. The production environment conforms to the "Technical Conditions for Tobacco Production Environment (NY / T852-2004)".

[0040] 2. Flue-cured tobacco seedling raising

[0041] According to the test requirements and combined with the ecological conditions, the main planting variety of the base unit was determined to be Yunyan 87. The quality of the seeds complied with "Tobacco Seeds (GB / T 21138-2007)", "Tobacco Coated Seeds (GB / T25240-2010)" and "Tobacco Coated Seeds Heavy Metal Limits (YQ25-2013)". The flue-cured tobacco seedlings are entrusted to professional commerc...

Abstract

The invention provides an acidic tobacco planting soil pH value regulator and application thereof, and relates to the technical field of soil improvement. According to the invention, a drip irrigationfacility for supplying irrigation water to flue-cured tobacco is utilized, additional investment is not increased, the acidity and alkalinity of acidic tobacco planting soil are adjusted, and the pHvalue of the soil is adjusted to be larger than or equal to 6.0; and when the regulator is used for increasing the pH value of soil, the occurrence and development of tobacco bacterial wilt and blackshank are not facilitated, the morbidity is reduced, the tobacco quality is improved, and the unit area yield and planting benefit of tobacco are increased.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to an acidic tobacco planting soil pH regulator and application thereof. Background technique [0002] Soil acidity and alkalinity refer to the existence of various chemical and biochemical reactions in the soil, showing different acidity or alkalinity. The strength of soil acidity and alkalinity is often measured by pH. The reason why the soil is acidic and alkaline is because there are a small amount of hydrogen ions and hydroxide ions in the soil. When the concentration of hydrogen ions is greater than the concentration of hydroxide ions, the soil is acidic; otherwise, it is alkaline; when the two are equal, it is neutral. Most of the soil pH in my country is in the range of 4.5 to 8.5, and the pH value increases from south to north. The soil south of the Yangtze River (33°N latitude) is mostly acidic and strongly acidic, such as the red soil and yellow soi...
