Embodiment Construction

[0029] The following is further described in detail through specific implementation methods:

[0030] The reference signs in the drawings of the description include: outer cylinder 1, inner cylinder 2, mist-catching cotton 3, seepage hole 4, water diversion plate 5, bentonite 6, cross bar 7, heating box 8.

[0031] This embodiment discloses a method for acidifying farmland acidified soil, which specifically includes the following steps:

[0032] S1. Covering soil: spread dry straw, peanut shells, and weeds on the farmland, ignite and burn, and form a biochar layer on the surface of the farmland.

[0033] S2. Soil loosening: A rotary tiller is used to loosen the soil on the farmland, so that a loose soil layer is formed on the surface of the farmland. The depth of the loose soil layer is 30-40mm, and the depth of the loose soil layer in this embodiment is selected as 35cm. In the process of loosening the soil, biochar can also be mixed into the soil, so that the biochar can co...

Abstract

The invention relates to the technical field of soil improvement, and particularly discloses an acidity changing method for acidified soil in a farmland. The method comprises the following steps that1, a soil loosening layer of which the depth is 30-40 cm is formed on a surface layer of the farmland; 2, a first soil conditioner is applied, wherein the first soil conditioner comprises dolomite dust, a calcium magnesium phosphate fertilizer and an organic fertilizer; 3, the first soil conditioner and the soil loosening layer are stirred uniformly; 4, a second soil conditioner is applied, wherein the second soil conditioner comprises lime nitrogen particles; 5, the second soil conditioner and the upper layer of the soil loosening layer are stirred uniformly, and the stirring depth is 10-15 cm; 6, water is applied to the soil loosening layer, so that the second soil conditioner is in sufficient contact with water; 7, crops are sown, wherein after water is applied for at least two days, the crops are sown on the soil loosening layer, and the sowing depths of the crops are less than 10 cm. The acidity changing method for the acidified soil in the farmland has the advantages that the acidity and alkalinity of the soil is changed within a short time by using the second soil conditioner, the pH value of the soil is improved, then the acidity and alkalinity of the soil is changed for along time by using the first soil conditioner, and the pH value of the soil is controlled, thereby avoiding soil acidification.

Description

technical field [0001] The invention relates to the technical field of soil improvement, and specifically discloses a method for acidifying farmland acidified soil. Background technique [0002] Soil pH is an important chemical property of soil, which directly affects soil nutrient content, nutrient availability and soil microbial activity, and then affects the growth and development of crops. Soil acidification refers to the phenomenon that the increase of hydrogen ion concentration in the soil causes the decrease of soil pH value under natural and artificial conditions, and it is a manifestation of soil degradation. Soil acidification will lead to a decrease in soil base saturation and leaching of nutrients, reducing soil storage capacity and resulting in a decrease in soil productivity. At present, the main reason affecting soil acidification is the impact of human industrial activities and agricultural activities, mainly in the form of acid rain and irrational applicati...
