Problems solved by technology

[0002] In addition to natural precipitation and surface water, the most important way to supply water to plant roots is artificial irrigation, which has two major defects, water leakage and evaporation, especially in high-temperature and arid areas; the nutrients required for plant growth, in addition to Besides the nutrients contained in the soil, it is mainly artificial fertilization, and artificial fertilization has defects such as the loss of fertilizer nutrients or not being absorbed by plants or the absorption ratio is small, especially in areas with poor soil

Embodiment 1

[0015] Production and application of slow-release water-supply fertilizer

[0016] The weight ratio of the fertilizer components is: water accounts for 95%, urea accounts for 4%, thickener accounts for 0.80%, and curing agent accounts for 0.20%.

[0017] The fertilizer is added to the water, and the fertilizer is dissolved or mixed with the water by stirring.

[0018] Slowly and evenly add the thickener into the water-fertilizer mixed solution, and mix the water, fertilizer and thickener thoroughly by stirring to form a jelly or paste-like object.

[0019] Slowly and evenly add the curing agent into the above colloidal liquid, and flocculate the colloidal substance by stirring.

[0020] Put the jelly object into a container or a plastic bag and seal it for later use, or directly bury the jelly object near the root of the plant to supply water and fertilizer for the plant for a long time.

[0021] If it is produced in a factory, the components should be sterilized in advance ...

Embodiment 2

[0025] Production and application of slow-release water-supply fertilizer

[0026] The weight ratio of the fertilizer components is: water accounts for 91%, potassium fertilizer accounts for 7%, thickener accounts for 2.0%, and curing agent accounts for 0.0%.

[0027] The fertilizer is added to the water, and the fertilizer is dissolved or mixed with the water by stirring.

[0028] Slowly and evenly add the thickener into the water-fertilizer mixed solution, and stir to fully mix the water, fertilizer and thickener together to form a jelly-like object.

[0029] Put the jelly object into a container or a plastic bag and seal it for later use, or directly bury the jelly object near the root of the plant to supply water and fertilizer for the plant for a long time.

[0030] The thickener is agar.

Embodiment 3

[0032] Production and application of slow-release water-supply fertilizer

[0033] The weight ratio of the fertilizer components is: water accounts for 90.00%, phosphate fertilizer accounts for 4%, thickener accounts for 5.00%, and curing agent accounts for 1.00%.

[0034] The fertilizer is added to the water, and the fertilizer is dissolved or mixed with the water by stirring.

[0035] Slowly and evenly add the thickener into the water-fertilizer mixed solution, and stir to fully mix the water, fertilizer and thickener together to form a jelly-like object.

[0036] Slowly and evenly add the curing agent into the above colloidal liquid, and flocculate the colloidal substance by stirring.

[0037] Put the jelly object into a container or a plastic bag and seal it for later use, or directly bury the jelly object near the root of the plant to supply water and fertilizer for the plant for a long time.

Abstract

The invention relates to fertilizers, and in particular relates to a slow-release water supply type fertilizer and an application thereof. The slow-release water supply type fertilizer comprises the following components: water and fertilizer together accounting for 94-99.5 percent in total, a thickening agent accounting for 0.50-5.00 percent in total, and a slow release agent accounting for 0.00-1.00 percent. Moisture and fertilizer nutrients contained in the slow-release water supply type fertilizer provided by the invention are slowly released to the root of a plant through biodegradation effects, so that soil is capable of providing the moisture and the nutrients to the plant for a long period of time.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a slow-release water-supply fertilizer and its application. Background technique [0002] In addition to natural precipitation and surface water, the most important way to supply water to plant roots is artificial irrigation, which has two major defects, water leakage and evaporation, especially in high-temperature and arid areas; the nutrients required for plant growth, in addition to Apart from the nutrients contained in the soil, it is mainly artificial fertilization, and artificial fertilization has defects such as loss of fertilizer nutrients or not being absorbed by plants or a small absorption ratio, especially in areas with poor soil. Contents of the invention [0003] In order to solve the above-mentioned shortcomings of existing irrigation and fertilization, the present invention provides a slow-release water-supply fertilizer. The slow-release water-supply fertilizer provided by the ...
