[0062] The preparation method of plant extract in embodiment 1-3 is as follows:
[0063] (1) In parts by weight, 4 parts of alfalfa, 3 parts of aloe and 3 parts of soybean were weighed and freeze-dried, and the freeze-dried plant material was ground to obtain plant powder.
[0064] (2) The plant powder is immersed in 20 parts by weight of low-temperature water for low-temperature ultrasonic extraction treatment, and the treatment temperature is 22 degrees.
[0065] (3) Filter the low-temperature extract to remove residues.
[0066] (4) Dilute the above extract with water to 3 times the original volume, add 0.6 parts of Ascophyllum nodosum, and mix well.
[0067] The preparation method of plant extract in embodiment 4-6 is as follows:
[0068] (1) In parts by weight, 5 parts of alfalfa, 2 parts of aloe and 3 parts of soybean were weighed and freeze-dried, and the freeze-dried plant material was ground to obtain plant powder.
[0069] (2) The plant powder is immersed in 25 pa...
Embodiment 1
[0073] (1) Mix 1000g of bentonite and 10g of calcium oxide evenly.
[0074] (2) Take 50 grams of plant extract and spray evenly on the mixture obtained in step (1), and keep stirring to make it fully mixed evenly, and then air-dry at room temperature for 1-2 days to obtain a soil conditioner.
[0075] The dosage depends on different crops and soil environment, generally 1-5kg / mu.
[0076] The following continues to combine specific applications and gives several examples.

Abstract
The invention discloses a soil conditioner which is prepared from plant extract, an adsorbent and an adhesive, wherein the raw materials of the plant extract include alfalfa meal, aloe powder and soybean meal; the adsorbent is prepared from one or more of mineral substances such as bentonite, kieselguhr, vermiculite, montmorillonite and illite or humic acids or humates; and the adhesive is prepared from calcium salt and oxide thereof. The soil conditioner has the effects of comprehensively improving physicochemical properties of soil, increasing the fertilizer utilization ratio, promoting plant growth and the like, can be used for improving degenerated soil such as hardened soil, saline-alkali soil and desert soil, and also can be applied as conventional fertilizer for melons and fruits, cereals, vegetables and other crops.
Description
technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a soil conditioner and its preparation method and application. Background technique [0002] International research on soil remediation technology can be traced back to the 1950s, and made great progress in the 1980s. Since 2000, domestic self-developed soil remediation products have gradually sprouted. At the first soil conditioner summit in 2012, someone pointed out: "Currently, the polluted cultivated land in the country has accounted for more than 10% of the total cultivated land area, reaching 150 million mu." , my country's soil restoration is facing severe challenges. [0003] At present, there are many kinds of soil remediation technology and equipment, which are divided into the following categories in terms of sources: (1) Minerals, mainly peat, lignite, weathered coal, lime, gypsum, vermiculite, bentonite, zeolite, perlite and sepiolite etc.; (2) ...
