Embodiment 1

[0055] Embodiment 1 basic performance detection method

[0056] Surface tension measurement

[0057] Precisely prepare a 1% (w / v) fertilizer solution and measure it using a SITAt-100 surface tensiometer.

[0058] Determination of N and P release performance of fertilizers

[0059] Fully mix 500mg of fertilizer and 2000 times the quality of desert soil; put it into a glass culture column, seal the bottom with three layers of gauze, place it on a support, and connect the bottom with a funnel and a beaker to soak in water. The water content of the mixture was maintained between 50-60% with distilled water throughout the experiment.

[0060] On the 0th day, 7th day, 14th day, 28th day, and 56th day, add distilled water equal to the volume of the soil and connect the exudate; use Kjeldahl method and vanadium molybdenum yellow colorimetric method to measure nitrogen and phosphorus in the exudate content.

Embodiment 2

[0061] The preparation of embodiment 2 soil conditioners

[0062] In the examples, only some representative results (renumbered for comparison) are shown, and a large number of exploratory experiments with similar methods / performances are not shown.

[0063]

[0064]

[0065] Among them: other ingredients include sodium molybdate 0.70%, sodium borate 0.20%, NTA chelated magnesium 0.20%, EDTA chelated zinc 0.20%, EDTA chelated copper 0.10%, EDTA chelated manganese 0.10% and microbial compound fermentation powder 3.5 %.

[0066] The chelating agent in soil conditioner 3-6 is EDDHA, and the chelating agent in soil conditioner 7 is DPTA.

Embodiment 3

[0067] The performance detection of embodiment 3 soil conditioner

[0068] Nitrogen release test results (release amount, mg)

[0069]

[0070] Phosphorus release test results (release amount, mg)

[0071]

[0072] From the release curve and the total amount of release, soil conditioner 4-6 has achieved a certain slow-release effect compared with soil conditioner 1-3 and 7, and the release curve of nitrogen and phosphorus is smooth, and after February (5 times of drip irrigation), it is still A certain amount of equivalent nitrogen and phosphorus are kept undissolved. This can reduce the frequency of fertilization in production, reduce the effect of drip irrigation on fertilizer efficiency, and evenly release the effect of improving fertilizer efficiency.

Abstract

The invention relates to the field of improvement of and planting with desert soil, in particular to a slow-release soil conditioner suitable for planting with desert soil and application of the slow-release soil conditioner. The slow-release soil conditioner in the invention comprises the following components in percentage by mass: 30 to 60% of natural peat soil, 3.0 to 10% of wormcast powder, 20to 40% of mineral-derived humus, 5.0 to 20% of urea, 1.0 to 5.0% of cyclic lipopeptide, 0.5 to 1.5% of a chelating agent and 1.0 to 10% of microorganism compound zymophyte powder. In the process of improving the wettability of the humic acid-containing soil conditioner, the problems of water shortage and lack of water in a medium desert soil environment are solved, the fertility of soil is improved, and the conditioned soil is suitable for wheat planting.

Description

technical field [0001] The application relates to the field of desert soil soil improvement planting, in particular to a slow-release soil conditioner suitable for desert soil planting and its application. Background technique [0002] Desert soil (desert soil) refers to the soil formed under arid desert conditions. Widely distributed in temperate and tropical desert regions, Africa, Oceania, Central Asia, North America, and South America are all distributed, accounting for about 10% of the earth's land area. Desert soils in China are classified into gray desert soils, gray brown desert soils, brown desert soils, cracked soils, etc. according to the temperature or drought degree. In China, it is mainly distributed in Inner Mongolia, Ningxia, Qinghai, Xinjiang and other provinces. Desert soil series include gray desert soil, gray brown desert soil, brown desert soil, cracked soil and other soil types. Gray-brown desert soil and brown desert soil represent typical desert so...
