Embodiment 1

[0035] The components of the agricultural mulch film are calculated in parts by weight, including: 64 parts of matrix resin, 30 parts of sustained-release capsules, 4 parts of talcum powder, 1 part of monoglyceride, and 1 part of polyethylene wax;

[0036] The raw materials of the sustained-release capsule are calculated in parts by weight, including: 20 parts of garlic oil, 30 parts of hydrotalcite, 47 parts of modified starch, and 3 parts of cross-linking agent;

[0037] The matrix resin is ethylene-vinyl acetate copolymer; the crosslinking agent is succinic dialdehyde;

[0038] The concrete steps of preparation are:

[0039] (1) Mix garlic oil and ethanol at a volume ratio of 4:1, stir and dissolve, use an atomizing device to atomize the mixed solution into 0.3mm fine droplets, and spray it between the hydrotalcite layers through a spray gun. Cooling and solidification during the flight form a solid-liquid two-phase particle jet stream, which is sprayed onto the hydrotalci...

Embodiment 2

[0045] The components of the agricultural mulch film are calculated in parts by weight, including: 77 parts of matrix resin, 20 parts of sustained-release capsules, 2 parts of talcum powder, 0.5 parts of monoglyceride, and 0.5 parts of polyethylene wax;

Abstract

The invention provides sustained release agricultural plastic mulch used for preventing and controlling bacterial wilt and a preparation method thereof. Garlic oil is injected among hydrotalcite layers by carrying out atomized spray, effective adsorption is formed, and hydrotalcites loaded with the garlic oil and a crosslinking agent are added into starch suspension, so that starch molecules are crosslinked and cured and coat the hydrotalcites loaded with the garlic oil inside, and sustained release capsules are obtained; and the sustained release capsules are mixed with matrix resin, and thenfilm blowing is carried out, so that the sustained release agricultural plastic mulch capable of preventing and controlling the bacterial wilt is obtained. The preparation method utilizes that a garlic oil sterilization layer can inhibit or alleviate bacterial wilt disease of multiple crops and has a good fungi-proofing effect, and the sustained release capsules have good compatibility with the matrix resin and are uniformly dispersed, so that the mulch has high strength and also has sustained release performance, sterilization time effect is long, and low cost and high efficiency are achieved in the whole preparation process.

Description

technical field [0001] The invention relates to the technical field of agricultural mulch, in particular to a slow-release plastic mulch for preventing and controlling bacterial wilt, and in particular to a slow-release agricultural plastic mulch for preventing and controlling bacterial wilt and a preparation method thereof. Background technique [0002] Agricultural film is an important agricultural production material after seeds, fertilizers and pesticides. Its application has brought a revolution to agricultural production and made important contributions to increasing agricultural efficiency and farmers' income. Agricultural mulch film has the functions of moisturizing, heat preservation, insect resistance, disease prevention, and inhibition of weed growth, which is beneficial to crop growth and development, increases crop yield, and improves agricultural benefits. Due to the use of agricultural mulch film, the temperature and humidity of the soil are effectively contro...
