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 quickly increasing fertility of barren acid red soil. The method for quickly increasing fertility of barren acid red soil includes step (1) of first cultivating the acid red soil into cultivated land, and performing combined application of humic acid fertilizer at 3-6 tons / mu; step (2) of applying thoroughly decomposed commercial organic fertilizer at 1-3 tons / mu, soil conditioning agent at 10-50 kg / mu and organic liquid fertilizer at 10-30 kg / mu; step (3) of turning over the humic acid fertilizer, the commercial organic fertilizer, the soil conditioning agent, the organic liquid fertilizer and plough layer soil in steps (1) and (2) into soil many times, and performing uniform mixing. By the adoption of the technology, the soil fertility level is increased quickly and effectively, and the increase of the crop yield 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 thin. [0003] The development and ut...
