Problems solved by technology

[0004] The newly reclaimed acidic red soil has low fertility and poor aeration, which is not conducive to the growth of crops. The existing acidic red soil improvement technology is slow to improve soil fertility. It takes years or even decades to cultivate high-fertility soil. To achieve the purpose of efficient utilization in the year of reclamation

Embodiment 1

[0023] In 2017-2018, the barren soil block of red soil type was selected in Fuli Village, Qujiang District, Quzhou City. This piece of land was originally dominated by orchards, wasteland, and medium and low-yield fields, and the soil organic matter content was 0.48%. Transformation, to investigate the content of soil organic matter and rice planting yield after transformation.

[0024] According to the improvement method of fertilization of the present invention: at first cultivate the paddy field type by land leveling engineering. According to the soil fertility level of the field soil, 5 tons / mu of humic acid fertilizer was applied in early April 2017, and the soil fertilization test was carried out. At the same time, 2 tons / mu of decomposed commercial organic fertilizer, 20kg / mu of soil conditioner, and 20kg / mu of organic liquid fertilizer were applied. After the above-mentioned fertilizer is evenly applied to the soil, the fertilizer is pressed into the soil with a small...

Embodiment 2

[0035] In 2017-2018, a barren soil block of red soil type was selected in Maqi Village, Quanwang Town, Qujiang District, Quzhou City. The land was originally dominated by red soil hilly wasteland. The reclamation was completed in August 2017, and the soil organic matter content was 0.25%. The method of the invention is used to transform the acidic red soil, and the soil organic matter content and rapeseed planting yield after transformation are investigated.

[0036] According to the improvement method of fertilization of the present invention: at first cultivate the paddy field type by land leveling engineering. According to the soil fertility level of the field soil, 6 tons / mu of humic acid fertilizer was applied at the end of August 2017, and the soil fertilization test was carried out. At the same time, 1 ton / mu of decomposed commercial organic fertilizer, 40kg / mu of soil conditioner, and 15kg / mu of organic liquid fertilizer were applied. After the above-mentioned fertili...

Abstract

The invention discloses a method for rapid fertilization of barren acid red soil. The method for rapid fertilization of barren acid red soil comprises the following steps, including (1) first reclamating acid red soil into arable land, and applying humic acid fertilizer 3- 6 tons / mu; (2) 1-3 tons / mu of commercial organic manure, 10-50kg / mu of soil conditioner, 10-30kg / mu of organic liquid fertilizer that are equipped with decomposed products simultaneously; (3) combine steps (1) and The humic acid fertilizer, commercial organic fertilizer, soil conditioner, and organic liquid fertilizer in step (2) are overturned and pressed into the soil for several times and mixed evenly. By adopting the technology of the invention, the increase of soil fertility level can be rapidly and effectively promoted, and the increase of crop output is very obvious.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a method for quickly fertilizing barren acidic red soil. Background technique [0002] Acidic soil is the general term for soil with a pH value less than 7. Including brick red soil, red soil, red soil, yellow soil and dry red soil and other soil types. In the tropical and subtropical regions of my country, acidic soils of various red or yellow soils are widely distributed. The local temperature is high and the rainfall is heavy, with the annual rainfall mostly above 1500mm. The characteristics of high temperature, rainy season, and hot and humid seasons make the weathering and pedogenesis of the soil very strong, and the cycle of biological matter is very rapid. The base is highly unsaturated and the pH is generally 4.5-6. At the same time, iron and aluminum oxides are obviously accumulated, and the soil is sour and lean. [0003] The development and ut...
