Embodiment 1

[0024] A kind of acid soil conditioner, adopts following steps to prepare:

[0025] Step A: mixing the carbon-based sugar factory filter mud with rice bran, the carbon-based sugar factory filter mud accounts for 90% by mass, and the rice bran accounts for 10% by mass;

[0026] Step B: In the fermentation plant with sunshade and rain shelter, mix the carbon-based sugar factory filter mud and rice bran into strips with a bottom width of 3-4 meters, a top width of 1.5-2.0 meters, and a height of 1.8-2.0 meters. fermentation;

[0027] Step C: Turn the pile every 7-9 days, and after 22-30 days of natural fermentation, the acidic soil improver is obtained.

[0028] Carry out field test below, the pH value of the acidic soil of test is 6.07, adopt the acidic soil improver that this example obtains to carry out soil improvement, apply according to 100-150 kg / mu, plant sugarcane. Simultaneously, plant sugarcane on the soil that does not use soil improver, as blank control example; Ca...

Embodiment 2

[0033] Adopt the acidic soil improver that embodiment 1 obtains to carry out field test, the pH value of the acidic soil of test is 5.13, adopt the acidic soil improver that present embodiment 1 obtains to carry out soil improvement, apply according to 100-150 kilogram / mu, plant sugar cane. Simultaneously, plant sugarcane on the soil that does not use soil improver, as blank control example; Carry out field test with sulfite method filter mud as soil improver, apply according to 100-150 kg / mu, as comparative example; The sugarcane yield and soil pH value were compared, as shown in Table 2.

[0034] As can be seen from Table 2, the sugarcane planted in the soil using the acidic soil improver of the present invention has an increase of 407 kg / mu compared with the unapplied one, an increase of 7.27%, and the pH value of the acidic soil has also increased by 0.02. After testing, the soil bulk density decreases by 0.02 . However, in field experiments using sulfurous acid filter m...

Embodiment 3

[0044] On the basis of embodiment 1, in the acidic soil improver described in this example, the mass percentage that the carbon process sugar factory filter mud accounts for is 85%, and the mass percentage that rice bran accounts for is 15%, and other preparation methods are all the same as embodiment 1 The preparation method of acidic soil conditioner described in.

[0045] A field test is carried out by using the obtained acidic soil improver, and the pH value of the tested acidic soil is 4.53. The obtained acidic soil improver is used for soil improvement, and is applied according to 100-150 kg / mu, and sugarcane is planted. At the same time, sugarcane was planted on the soil without soil improver as a blank control; a field test was carried out with sulfite filter mud as a soil improver, and it was applied at 100-150 kg / mu as a comparative example; The sugarcane yield and soil pH value were compared, as shown in Table 4.

[0046] As can be seen from Table 4, the sugarcane ...

Abstract

The invention provides an acidic soil improver and a preparation method thereof. The acidic soil improver is prepared by the following method: mixing the carbon-based sugar factory filter mud with rice bran, and the mass of the carbon-based sugar factory filter mud is The percentage is 85%~95%, and the mass percentage of rice bran is 5%~15%; the mixture of carbon sugar factory filter mud and rice bran is piled into a bottom width of 3‑4 meters, a top width of 1.5‑2.0 meters, and a height of 1.8‑ 2.0 meters of strips were allowed to ferment naturally to obtain the acidic soil conditioner. Adopting the technical scheme of the present invention can increase the pH value of acidic soil and have a good effect of increasing production; by using carbon-based sugar factory filter mud to manufacture soil improvers, resource utilization can be carried out in agricultural production, returning to nature, both It can solve the pollution problem of carbon-based sugar factory filter mud to the environment, and at the same time solve the problem of acidic soil improvement in agricultural production, turn waste into treasure, protect the environment, and promote the sustainable development of the sugar industry; and the cost is low, and it has a good popularity.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a soil conditioner, in particular to an acidic soil conditioner and a preparation method thereof. Background technique [0002] Guangxi is the largest sugar industry base in my country, and its cane sugar production accounts for about 70% of the country's total. The sugar cane industry is an important economic pillar in Guangxi. Each ton of sugar cane produces about 3% of filter mud during the sugar extraction process. However, due to various reasons, the carbon-based sugar factory filter mud has been discharged randomly for a long time, causing serious environmental pollution. In fact, the components in the carbon-based sugar factory filter mud are mainly various nutrients absorbed by sugarcane from the soil and various organic substances synthesized in the body, which are nitrogen, phosphorus, potassium and other large and trace amounts necessary for crop growth. Nutrients s...
