Description
Technical Field
The invention belongs to the field of agricultural application, and relates to a biodegradable agricultural film containing insect pheromone and a preparation method thereof.
Background
With the continuous improvement of modern people's living standard, people have higher and higher requirements on the variety and quality of vegetables, and the agricultural greenhouse is an agricultural facility for improving the yield of crops, improving the quality and implementing out-of-season planting to improve the agricultural production efficiency and benefit, and is widely applied to the field of vegetable planting. In the planting process of different seasons, prodenia litura, beet armyworm and diamond back moth are three major pests of vegetables, have high reproduction rate, wide host range and strong diffusion capacity, and greatly influence the quality and yield of the vegetables.
At present, chemical pesticides are adopted to prevent and treat vegetables, the prevention and treatment effects are increasingly poor along with the application process of the pesticides, and the quality of the vegetables is reduced due to the influence of chemical components. Meanwhile, chemical pesticides can cause certain toxic pollution and influence the ecological environment. Due to the increasing requirements for vegetable quality and environmental protection, the research of using insect pheromones to prevent and control insect pests is increasingly gaining attention. According to the physiological and biochemical characteristics and the behavioral characteristics of insects, the insect pheromone can cause the male insects to be 'disoriented' and interfere mating to achieve the effect of preventing and controlling insect pests.
Most of the insect pheromone products in the current market place a device with the insect pheromone at a fixed point to achieve the effect of preventing and controlling insect pests, but the application mode has a plurality of defects and can not be applied in a large scale, for example, the application mode of the fixed point placement can not achieve full coverage and the concentration of the insect pheromone in the space is not uniform, but the part with lower concentration is seriously damaged; the using mode is greatly influenced by weather and rain, and the releasing process is lack of long-term effectiveness.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a biodegradable agricultural film containing insect pheromone and a preparation method thereof, which solve the problems of uneven distribution and short long-acting property of the insect pheromone in the using process of the existing product and achieve the effects of uniform release and long-acting prevention and control.
In order to achieve the purpose, the invention adopts the following technical scheme to realize the purpose:
the invention discloses a preparation method of a biodegradable agricultural film containing insect pheromone, which comprises the steps of carrying out melt blending on hydrophilic modified PBS and the insect pheromone to prepare composite master batches, and carrying out film blowing on the obtained composite master batches to prepare the biodegradable agricultural film containing the insect pheromone.
Preferably, the insect pheromones include: at least one of (Z) -11-hexadecenal, (Z) -11-hexadecen-1-ol acetic acid, (Z) -11-hexadecenol, (Z, E) -9, 12-tetradecadiene-1-ol acetate, and (Z) -9-tetradecenol.
More preferably, (Z) -11-hexadecenal, (Z) -11-hexadecen-1-ol acetic acid, (Z) -11-hexadecenol, (Z, E) -9, 12-tetradecadiene-1-ol acetate, and (Z) -9-tetradecenol are compounded in a mass ratio of 0-1: 0-1.2: 0-0.8: 0-1: 0-0.5, wherein at least one of the mass ratios is not zero.
Preferably, the mixing mass ratio of the hydrophilic modified PBS to the insect pheromone is 1: 0.2-0.3.
Preferably, the temperature of the melt blending is 110-120 ℃, and the temperature of the film blowing process is 130-150 ℃.
Preferably, the hydrophilically modified PBS is prepared by the following steps: uniformly mixing butanediol, succinic acid and a third monomer, performing dehydration condensation reaction to obtain a reaction mixture, adding butyl titanate into the obtained reaction mixture to perform polymerization reaction to obtain a viscous product mixture, cooling the obtained viscous product mixture, and removing impurities to obtain hydrophilic modified PBS; wherein, the third monomer is polyhydroxy hydrophilic monomer.
Further preferably, the hydrophilic polyhydroxy monomer is glycerol, trihydroxymethylpropane, trimethylolethane, anhydrous phloroglucinol, phloroglucinol dihydrate, 1,2, 4-benzenetriol, 2, 3, 4-trihydroxybenzaldehyde, 1,4, 5-trihydroxy-2-pentanone or 1,3, 5-trihydroxy-2-bromobenzene.
More preferably, the molar ratio of the butanediol to the succinic acid to the third monomer is 1:1: 0.15-0.30; the butyl titanate is 0.3-0.8% of the butanediol.
Further preferably, the temperature of the dehydration condensation reaction is 160-170 ℃ and the time is 3-3.5 h.
Further preferably, the temperature of the polymerization reaction is 210 to 220 ℃.
The invention also discloses a biodegradable agricultural film containing the insect pheromone, which is prepared by the preparation method.
Compared with the prior art, the invention has the following beneficial effects:
the invention discloses a preparation method of a biodegradable agricultural film containing insect pheromone, which adopts a biodegradable material PBS as a matrix and selects a hydrophilic modified PBS, so that the hydrophilicity and the water retention of the agricultural film are improved, and the growth environment of greenhouse vegetables is improved. Insect pheromone is added, and the effect is released to the air through the degradation characteristic of the insect pheromone, so that the male insects are attracted, and the female insects cannot be positioned for mating, so that the effect of preventing and treating insect pests is achieved by interfering mating, and the effect of preventing and treating prodenia litura, beet armyworm and plutella xylostella is achieved. The preparation method disclosed by the invention is simple, low in energy consumption, time-saving and convenient to machine and form, and lays a foundation for the use of various agricultural films.
Further, by selecting a reasonable insect pheromone substance, targeted control can be performed on different types of pests. Meanwhile, the defects of poor control effect and environmental pollution of the traditional pesticide are overcome, and the effect of controlling insect pests is achieved.
Furthermore, the third type of hydrophilic monomer of polyhydroxy is selected to modify PBS, so that the hydrophilicity and the water retention of the agricultural film are improved, the growth environment of greenhouse vegetables is improved, the compatibility of PBS is increased, and the PBS can be better blended with insect pheromone. By synthesizing degradable PBS as a coating material and releasing the insect pheromone through the slow degradation of the PBS, the problems of uneven distribution and short long-acting property of the insect pheromone in the existing use process are solved, and the problem of recycling the discarded agricultural film is solved.
The invention discloses a biodegradable agricultural film containing insect pheromone, which is prepared by the preparation method, wherein the biodegradable agricultural film containing the insect pheromone is used for replacing the traditional chemical insecticide, and the insect pheromone is slowly released by the slow degradation of the agricultural film, so that the long-acting control effect is achieved. Meanwhile, the problem of environmental pollution caused by chemical pesticides is reduced, and higher-quality vegetables can be obtained. The biodegradable agricultural film is degraded in use and fully absorbed by soil, so that higher added value is given to the agricultural film, and the agricultural film conforms to the sustainable development of agriculture and the development direction of green agriculture.
