Embodiment approach 1

[0025] Select 100g of Jiaohe peat (organic matter 57%, water content 25%) in Jilin Province, crush and screen the particle size below 6mm, and use the water-retaining agent biodegradable superabsorbent resin developed by Northeast Normal University (pH7.5, moisture 5%, particle size 0.2mm) ) 1g, pulverize and sieve particle size below 1mm, after mixing evenly, add in 1000g (after air-drying, water content 30%) in the wind-blown sandy soil of western Jilin Province, as plow layer, sow Chinese cabbage, the result after 40 days shows: with contrast 100% wind-blown sandy soil In comparison, the bulk density of the soil decreased by nearly 313%, the content of organic matter increased by nearly 789%, the content of humic acid increased by 110%, the height of cabbage increased by 154%, and the dry weight increased by 359%.

Embodiment approach 2

[0027] Jilin Province Shuangyang peat (58% organic matter, water content 30%) 80g, crushed and screened particle size below 6mm, sapropel (water content 44%, organic matter content 3.5%) 320g, crushed and screened particle size below 4mm, and the biological quality assurance developed by Northeast Normal University Water agent (pH7.5, moisture 5%, particle size 0.2mm) 1.5g, crushed and screened particle size below 1mm, after mixing evenly, add to 1000g of wind-sand soil in the west of Jilin Province (after air-dried, water content 30%), as the cultivation layer, sow For cabbage, the results after 40 days showed that compared with the control 100% aeolian soil, the bulk density of the soil decreased by nearly 20%, the content of organic matter increased by nearly 600%, the content of humic acid increased by 119%, the height of cabbage increased by 250%, and the dry weight increased by 455%.

Embodiment approach 3

[0029] Select 120g of Shuangyang peat (58% organic matter, 30% water content) in Jilin Province, crushed and screened with a particle size of 2mm or less, 280g of sapropel (44% water content, 3.5% organic matter content), crushed and screened with a particle size of 2 mm or less, and the water-retaining product developed by Northeast Normal University. 1g of biodegradable superabsorbent resin (pH7.5, moisture 5%, particle size 0.2mm), after mixing evenly, granulate for 5 minutes while spraying water, dry for 20 minutes, and cool, the specification is particle size 1 ~ 3mm , Strength 15-30N, moisture 5-10%. Add it to 1000g of wind-blown sandy soil in the west of Jilin Province (after air drying, water content 30%), then plant Chinese cabbage, the results after 40 days show: compared with the control, the bulk density of the soil decreased by nearly 25%, the organic matter content increased by nearly 900%, and the humic acid content 154% increase, 195% increase in cabbage height...

Abstract

The present invention belongs to the field of soil conditioner, and is especially one kind of aeolian sandy soil conditioner and its usage. The aeolian sandy soil conditioner consists of turf and sapropel as natural organic matters and biological moisture keeping agent of high hydroscopicity resin synthesized with corn. It may be powder or grain, and can regulate the solid, liquid and gas proportion of aeolian sandy soil, decrease its unit weight, improve soil aggregate structure, increase organic matter and humic aid content, raise the physical, chemical and biological performances of soil, and make the soil suitable for crop to grow. When it is used, the aeolian sandy soil conditioner is mixed with aeolian sandy soil containing water in 20-40 % in the weight ratio of 10-77 to 100.

Description

technical field [0001] The invention belongs to a soil conditioner, and relates to a sandstorm soil conditioner and its preparation and use method. Background technique [0002] Aeolian soil is a soil type developed on the sandy parent material in aeolian sand area. It is divided into three types (or three development stages) of mobile aeolian soil, semi-fixed aeolian soil and fixed aeolian soil. In my country, aeolian sandy soil is mainly distributed in arid and semi-arid areas in the north, including vast areas from grasslands, semi-deserts to deserts. [0003] Aeolian sandy soil has low fertility, poor structure, and is prone to water and fertilizer. It is a low-yielding soil type. To obtain high and stable yields, it is necessary to improve the aeolian sandy soil and apply more fertilizers, especially organic fertilizers. [0004] Chi Fengqin, Institute of Soil and Fertilizer, Heilongjiang Academy of Agricultural Sciences, studied the law of decomposition of several org...
