Problems solved by technology

In this way, it is easy to produce phytotoxicity, increase pesticide residues, endanger human health, pollute the environment, and is labor-intensive and time-consuming, which is very uneconomical.
In addition, although the current agricultural water-retaining agents have strong water-absorbing and water-retaining properties, they do not have the nutrients necessary for crop growth.

Abstract

The invention discloses a fermented water retention type sustained-release preparation and a preparation method thereof. The sustained-release preparation is characterized by comprising the following raw materials by weight: 100 parts of acrylic acid, 15-20 parts of straw fermentation broth, 5-7 parts of urea, 2-3 parts of trifluralin, 3-4 parts of fomesafen, 8-12 parts of sepiolite, 0.07-0.08 part of an initiator, 0.08-0.12 part of a crosslinking agent, 4-6 parts of sawdust, 3-4 parts of borax, 3-4 parts of polyvinyl alcohol, and 1.5-1.8 parts of guar gum. According to the invention, the weeding and insecticidal effective organic components and the organic fermentation broth are integrated, the fermentation broth provides sufficient organic matters for plant growth, the crop resistance to diseases is improved, the water absorption and drainage capacity is strong, the water permeability and air permeability of soil are enhanced, and the sustained-release effect of fertilizer is enhanced, the fermented water retention type sustained-release preparation has good biocompatibility, and is beneficial to sustainable development of resources.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a fermented water-retaining slow-release preparation and a production method. Background technique [0002] In agricultural production, the occurrence of harmful organisms is one of the important factors leading to the reduction of grain production, and spraying pesticides is an effective way to prevent and control pests and diseases, increase grain production, and ensure high agricultural yields. Traditional conventional pesticide preparations have disadvantages such as fast release of active ingredients, short duration of drug effect, and large dosage, and the utilization rate is generally only 20% to 30%. In order to maintain a certain efficacy, it is necessary to spray a higher dose than the effective dose, or increase the frequency of spraying. This is easy to produce phytotoxicity, increases pesticide residues, endangers human health, pollutes the...
