Abstract
本发明制备了一种新型植物保护剂，该新型植物保护剂是将一定比例的壳聚糖、高岭土、丙三醇、冰醋酸、水充分搅拌均匀，然后按一定倍数稀释，喷洒于植株上。本发明提供的新型植物保护剂各组分对生产者及使用者安全无毒副作用，对生态环境无负面影响，该新型植物保护剂具有更好的防水冲刷能力、更好的铺展能力，可以物理阻隔多种害虫，且具有一定的协同抗病能力。The invention prepares a new type of plant protection agent. The novel plant protection agent is prepared by fully stirring a certain proportion of chitosan, kaolin, glycerol, glacial acetic acid and water, and then diluting it by a certain multiple and spraying it on the plants. The components of the novel plant protection agent provided by the present invention are safe for producers and users, have no toxic and side effects, and have no negative impact on the ecological environment. Block a variety of pests, and has a certain synergistic disease resistance.
Description
Technical field
The invention belongs to field of biological control, and the present invention relates to a kind of novel plant protective agents, more particularly to
One kind being aided with the plant protection product with certain resistant to diseases and insects of chitosan, glycerine preparation using kaolin as main component.
Background technique
Kaolin is a kind of with the alumina silicate clay as main component with strong plasticity, belongs to 1: 1 type laminar silicic acid
Salt.High-purity kaolin has that whiteness is high, matter is soft, easy dispersion suspends in water, high caking property, excellent electrical insulation capability etc.
Feature, therefore kaolin has become necessary to tens industries such as papermaking, ceramics, rubber, chemical industry, coating, medicine and national defence
Raw mineral materials.
1992, modified kaolin was coated on plant leaf blade by U.S. entomologist using coating technique, it was demonstrated that
The coating can not only promote the healthy growth of plant, improve fruit quality, while can also reduce pesticide sales volume, play insect prevention
The purpose cured the disease.Patent 03104734.3 prepares a kind of green plant protecting agent using kaolin and auxiliary agent, the protective agent collection
The environment-stress such as light, heat, the water that insect prevention, diseases prevention, alleviation plant may be subject to are integrated, but contain toxic ratio in the patent auxiliary agent
Biggish methanol.
Chitosan is natural polysaccharide, as unique naturally occurring alkaline polysaccharide with safe and non-toxic, film forming is strong, antibacterial
And good biodegradability.Chitosan coating is in the existing part research report in agriculture related application field, such as chitosan
Film can effectively control the penicilliosis of jujube fruit, the white rot of grape, and chitosan coating fruit is able to suppress south jiangxi navel orange, grass
The fruits and vegetables such as the certain kind of berries, apricot store the decline of quality, extend storage time, improve commercial value.
However there is not the Case Report that the two is utilized in conjunction with to plant protection product related fields now.
Summary of the invention
The purpose of the present invention is develop a kind of novel plant protective agent for having both kaolin and chitosan property concurrently.
This novel plant protective agent, protective agent ingredient include: chitosan, kaolin, glycerine, glacial acetic acid, water.
Further, the novel plant protective agent each component weight ratio is chitosan: kaolin: glycerine: glacial acetic acid:
Water=1:1 ~ 20:0 ~ 10:0 ~ 10:20 ~ 200.
Further, in the novel plant protective agent, chitosan includes that different viscositys, different deacetylations and chitosan spread out
Biology.
Novel plant protective agent of the present invention, preparation method are as follows:
It takes 1 part of chitosan to be put into 0 ~ 10 part of glacial acetic acid of addition in 20 ~ 200 parts of water, is sufficiently stirred after being completely dissolved chitosan, adds
Enter 1 ~ 20 part of kaolin and plant protection product is made after mixing in 0 ~ 10 part of glycerine.
Novel plant protective agent of the present invention, disease-resistant method are as follows:
In field or field in use, novel plant is protected 20-100 times of dilution agent, dilution needs are shaken up, and use sprayer
Tool uniformly sprays plant stem-leaf.And it needs to spray under conditions of sunshine abundance, and solution needs uniform fold blade.
Novel plant protective agent of the invention has preparation simply, low in cost, to people and animals and the safe nothing of natural environment
Harmful feature.The protective agent can form certain thickness protective film on plant leaf blade, which has better waterproof
Scouring capability, better spreading ability, can not only insect prevention, moreover it is possible to improve plant for light, heat, the resistivity of water stress,
The presence of chitosan can cooperate with kaolin film layer to realize wider antibacterial action.
Specific implementation method
Embodiment 1: weighing 1g chitosan (deacetylation >=90%) and be added in 50ml water, 2g glacial acetic acid is added, 2h is sufficiently stirred,
After chitosan are completely dissolved, 6g kaolin, 2g glycerine are sequentially added, is stirred evenly, which is diluted to 500ml,
It is sprayed on plant stem-leaf using watering can.
Embodiment 2: it weighs 1g chitosan (deacetylation >=90%) and is added in 50ml water, 2g glacial acetic acid is added, is sufficiently stirred
2h sequentially adds 6g kaolin, 2g glycerine, stirs evenly, which is diluted to after chitosan is completely dissolved
1000ml is sprayed on plant stem-leaf using watering can.
Embodiment 3: it weighs 1g chitosan (deacetylation >=90%) and is added in 50ml water, 2g glacial acetic acid is added, is sufficiently stirred
2h is added 6g kaolin, stirs evenly, which is diluted to 500ml, is sprayed using watering can after chitosan is completely dissolved
It applies on plant stem-leaf.
Embodiment 4: it weighs 0.5g chitosan (deacetylation >=90%) and is added in 50ml water, 2g glacial acetic acid is added, sufficiently stirs
2h is mixed, after chitosan is completely dissolved, 6g kaolin, 2g glycerine is sequentially added, stirs evenly, which is diluted to

Field trial is carried out in Beijing Tongzhou tomato base, above 6 kinds of embodiments are respectively adopted and are handled as 6, simultaneously
It is compareed provided with the processing for not applying plant protection product as clear water, each processing area is 100 ㎡, with protection between each processing
Row separates.In above each processing region, five point sampling, 5 plants of tomato plants of every selection are taken respectively, and every plant of tomato is chosen
Each 5 leaves in upper, middle and lower are investigated, and 5 days after spray on plants protective agent, are investigated respectively white on plant in each processing region
Aleyrodid quantity and the gray mold disease number of sheets.Investigation result shows that plant protection product plays preferable trialeurodes vaporariorum, gray mold
Preventive effect (see Table 1).
Disease-resistant effect research table of 1 plant protection product of table to plant
