Liquid film preparation and preparation method thereof

Abstract

The invention relates to the field of agricultural planting, and discloses a liquid film preparation and a preparation method thereof. The liquid film preparation is prepared from the following components in percentage by weight: 15 to 25 percent of polyving akohol, 3 to 7 percent of silica sol, 3 to 7 percent of soluble starch, 5 to 15 percent of antibacterial aerobic granules, 3 to 7 percent of carboxymethylcellulose, 1 to 3 percent of glutaraldehyde, 1 to 3 percent of emulgator, 0.5 to 1.5 percent of defoaming agent, and the balance water. The liquid film preparation provided by the invention is good in film-forming property, has an excellent heat preservation and water retention effect, and has multiple functions such as antibiosis, oxygenation and slow release.

Description

Technical field [0001] The invention relates to the field of agricultural planting, in particular to a liquid mulching film preparation and a preparation method thereof. Background technique [0002] Plastic mulch is the most widely used mulch in the agricultural field. It can prevent wind, heat and retain water. However, the natural degradability of plastic mulch is poor, and the residue in the soil will destroy the soil structure and cause white pollution. Laying and recycling of the mulch is time-consuming and laborious, and the efficiency is low. There are also some degradable mulches on the market, but their cost is relatively high and it is difficult to promote. [0003] In recent years, the liquid mulch film has been developed rapidly. The liquid mulch film can absorb heat, increase moisture content, and protect seedlings. It also has a strong adhesion ability. It can connect soil particles into ideal aggregates, improve the capillary effect of soil particles, and improve ...

AI Technical Summary

Problems solved by technology

[0005] 1. Some of the current liquid mulches have poor film-forming properties on the surface after spraying, and their ability to keep heat and water in the soil is relatively insufficient.

[0006] 2. The current liquid mulch film has a single function. After spraying the mulch film, it forms a film on the soil surface, and when fertilizers, herbicides and other reagents are subsequently applied, the effect is poor due to the barrier of the mulch film.
