Embodiment 1

[0037] Embodiment 1 basic performance detection method

[0038] Surface tension measurement

[0039] Precisely prepare a 1% (w / v) fertilizer solution and measure it using a SITA t-100 surface tensiometer.

[0040] Determination of N and P release performance of fertilizers

[0041] Fully mix 500mg of fertilizer and 2000 times the mass of aeolian soil; put it into a glass culture column, seal the bottom with three layers of gauze, place it on a stand, 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.

[0042] 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

[0043] The preparation of embodiment 2 water-soluble fertilizer

[0044] Only some representative results (renumbered for comparison) are shown in the examples, and a large number of exploratory experiments with similar methods / performances are not shown.

[0045]

[0046] Among them: other ingredients include sodium molybdate 0.70%, sodium borate 0.20%, NTA chelated calcium 0.30%, NTA chelated magnesium 0.20%, EDTA chelated zinc 0.20%, EDTA chelated copper 0.10%, EDTA chelated manganese 0.10% and EDDHA Chelated Iron 0.20%.

[0047] The chelating agent in water-soluble fertilizer 3-6 is EDDHA, and the chelating agent in water-soluble fertilizer 7 is DPTA.

Embodiment 3

[0048] The performance detection of embodiment 3 water-soluble fertilizer

[0049] Surface tension test results (surface tension, mN / m)

[0050]

[0051] *Water-soluble fertilizers 2 and 7 (and some other unshown formulas that only add Savantine and do not contain EDDHA) appear obvious white precipitates after dissolution, which is speculated to be related to the isoelectric point of Savantine.

[0052] The surface tension of water-soluble fertilizer 4 with a mass ratio of Savantine and EDDHA of 5:1 is significantly higher than that of other ratios of water-soluble fertilizers and water-soluble fertilizers without the combination of Savantine and EDDHA. Higher surface tension means better dissolution properties and foliar / root absorption properties.

[0053] Nitrogen release test results (release amount, mg)

[0054]

[0055]

[0056] Phosphorus Release Test Results

[0057]

[0058] From the release curve and the total amount of release, water-soluble fertilize...

Abstract

The invention relates to the field of improvement of and planting with aeolian sandy soil, in particular to a slow-release water-soluble fertilizer suitable for planting with aeolian sandy soil and application of the slow-release water-soluble fertilizer. The slow-release water-soluble fertilizer suitable for planting with aeolian sandy soil in the invention comprises the following components in percentage by mass: 55 to 75% of mineral-derived humus, 5.0 to 20% of urea, 2.0 to 8.0% of diammonium phosphate, 5.0 to 15% of monopotassium phosphate, 1.0 to 5.0% of cyclic lipopeptide and 0.5 to 1.5%of a chelating agent. In the process of improving the wettability of the humic acid-containing water-soluble fertilizer, the problems of water shortage and lack of water in a medium aeolian sandy soil environment are solved, soil fertility is improved, and the improved aeolian sandy soil is suitable for potato planting.

Description

technical field [0001] The application relates to the field of soil improvement and planting in sandy soil, in particular to a slow-release water-soluble fertilizer suitable for planting in sandy soil and its application. Background technique [0002] Aeolian sandy soils are soils developed from aeolian sandy parent materials. Its main feature is that the mineral part of the soil is almost entirely composed of fine sand particles (0.25-0.05 mm in diameter); the stratification of the section is not obvious, only A layer (organic layer) and C layer (parent material layer) lack B layer (sedimentary layer). layer); severe wind erosion; the soil is in its infancy. Aeolian sandy soil is mainly distributed in North China, Northeast my country, and Northwest China, as well as ancient river channels and coastal beach areas in the Yellow River and Haihe Plains. Aeolian sand soil has uniform particle composition, but coarse texture, fast water seepage, low fertilizer and water leakag...
