Problems solved by technology

Saline-alkali soil contains a large amount of soluble salts, which is easy to form a strong alkaline environment, affecting the physiological functions and normal growth of crops, and destroying the soil aggregate structure can easily lead to problems such as soil compaction and poor drainage.
[0003] At present, in soil conditioning, chemical pesticides are usually used for soil sterilization and insecticide, which has the disadvantages of unsafe use and adverse effects on the growth and development of plants and the quality of crop products.

preparation example Construction

[0091] The embodiment of the present invention provides a kind of saline-alkali soil conditioner preparation method special for facility agriculture, such as figure 1 shown, including:

[0092] Step 1: Pretreatment of straw raw materials;

[0093] Step 2: preparation of plant sterilization and insecticide raw materials;

[0094] Step 3: Mix the raw materials prepared in the above-mentioned steps 1 and 2, the raw materials for improving the physical structure of the soil, and the organic alkali-reducing raw materials.

[0095] The working principle and beneficial effects of the above-mentioned technical solution are as follows: the present invention uses straw as a raw material, which has a wide range of sources and is renewable, and can supplement the lack of organic components in the soil;

[0096] The invention uses plant sterilizing and insecticidal raw materials to make soil improver, which can effectively solve the problem of soil-borne diseases and insect pests caused ...

Embodiment 1

[0112] The soil conditioner is made from the following raw materials in parts by weight:

[0113] Cotton Straw 1000; Garlic Extract 1.0;

[0114] Marigold Extract 30; Zanthoxylum bungeanum Extract 1.0;

[0115] Arborvitae leaf powder 3.3; Diatomaceous earth 250;

[0116] Humic Acid 300.

[0117] The preparation method is as follows:

[0118] (1) Cotton straw pretreatment: crush cotton straw into particles with a diameter of 0.1-0.3 cm, add 2.0 times the amount of water to it, and at the same time add a straw decomposing agent equivalent to 0.2% of the total weight of cotton straw, and the straw is decomposed The agent is prepared by the ratio of starter: brown sugar: water = 1:1:20. It is activated for 12 hours before use, and the above-mentioned cotton straw particles, water and straw decomposing agent are fully mixed to obtain a straw premix, and the straw premix is ​​controlled. The moisture content of the material is 60-65%; the above-mentioned straw premix is ​​stacke...

Embodiment 2

[0125] The soil conditioner is made from the following raw materials in parts by weight:

[0126] Cotton straw 900; Garlic extract 0.95;

[0127] Marigold extract 26; Zanthoxylum bungeanum extract 0.95;

[0128] Arborvitae leaf powder 3.0; Diatomaceous earth 220;

[0129] Humic acid 290.

[0130] The preparation method is as follows:

[0131] (1) Cotton straw pretreatment: crush cotton straw into particles with a diameter of 0.1-0.3 cm, add 1.8 times the amount of water to it, and at the same time add a straw decomposing agent equivalent to 0.3% of the total weight of cotton straw, and the straw is decomposed The agent is prepared by the ratio of starter: brown sugar: water = 1:1:20. It is activated for 8 hours before use, and the above-mentioned cotton straw particles, water and straw decomposing agent are fully mixed to obtain a straw premix, and the straw premix is ​​controlled. The moisture content of the material is 60-65%; the above-mentioned straw premix is ​​stacke...

Abstract

The invention provides a method for preparing a special saline-alkali soil improver for facility agriculture, comprising: step 1: pretreatment of straw raw materials; step 2: preparation of plant sterilizing and insecticidal raw materials; step 3: combining the above steps 1, 2 2 The prepared raw materials are mixed with soil physical structure improvement raw materials and organic alkali-reducing raw materials. The invention uses plant sterilizing and insecticidal raw materials to make soil improver, which can effectively solve the problem of soil-borne diseases and insect pests caused by repeated cropping of crops and continuous cropping obstacles in saline-alkali land in facility agriculture, and avoids the use of chemical pesticides and antibiotics to sterilize and kill soil insects, and has the advantages of using It is safe and will not have any adverse effects on the growth and development of plants and the quality of crop products; the raw materials of the present invention do not contain natural polymers and microbial preparations, and the soil improver of the present invention has low cost (800 yuan / ton) and is easy to use (It can be directly applied to the soil), stable and long-lasting, which is conducive to large-scale promotion and application.

Description

technical field [0001] The invention relates to the technical field of preparation of soil improvers, in particular to a method for preparing a special saline-alkali soil improver for facility agriculture. Background technique [0002] Facility agriculture is a modern agricultural method that uses engineering technology to efficiently produce animals and plants under relatively controllable conditions. Facility agriculture covers facility planting, facility breeding and facility edible fungi, etc. However, with the increase of the cultivation period of protected crops, soil salinization is becoming more and more serious; saline-alkali soil is under the comprehensive action of various natural environments and human activities, and salts directly participate in the formation process of soil, and are converted into salt (alkali) The soil formed by the process as the leading role is a general term for saline soil, alkaline soil and various salinized and alkaline soils. Saline-...
