Abstract
The invention provides a method for preventing watermelon fruits from pesticide pollution and disease and pest damage. High temperature and high humidity weather in a greenhouse are easy to induce the disease and pest damage of watermelons, and the normal control method is to spray pesticides. With the increasing of use frequency of the pesticides, the pesticide application quantity is increased, the pesticides remained on the fruits are continuously increased, so that the edible safety of the watermelons in the market is becoming more dubious. The invention provides a method for preventing the watermelon fruits from the pesticide pollution and the disease and pest damage, the problem that the watermelon fruits are easy to be polluted by the sprayed pesticides is solved by uniformly spraying polyvinyl alcohol solution on the withered watermelon fruits at one step, and moreover, the damage of various bacteria and pests suffered by the watermelon fruits during expanding can be prevented; the pesticide application quantity is reduced, and beneficial conditions for producing high-quality and nuisanceless watermelons are created.
Description
Technical field
The invention belongs to the cultivating watermelon technical field, particularly relate to a kind of method that prevents watermelon fruit pesticide pollution and the infringement of sick worm.
Background technology
Watermelon has another name called water melon, cold melon, summer melon, is the fruit of cucurbitaceous plant watermelon, because of being introduces from the Western Regions in the Han dynasty, so claim " watermelon ".Melon is rounded or oval, color of the leather has dark green, green, white or green folder snake etc.It is dense red, light red, yellow or white that flesh is, and the sugariness succulence clearly quenches one's thirst, and is good fruit in midsummer.Watermelon can be rated as " king in the melon ", except that not fatty and cholesterol, contains significant quantities of glucose, malic acid, fructose, Argine Monohydrochloride, tomatin and abundant materials such as vitamin C, is a kind of food of being rich in nutrition, pure, edible safety.Along with the rise of green house cultivation anti-season watermelon, the edible throughout the year watermelon of people is become a reality in recent years.
Along with increasing to the demand of anti-season watermelon on the market, green house plantation anti-season watermelon area is also more and more wider.Owing to have a moderate climate in the green house, make insect be difficult to rely on arctic weather to be eliminated, add that indoor hot and humid weather very easily brings out the several diseases insect pest of watermelon, the conventional control method is all sprayed insecticide.Along with the drug-fast continuous enhancing of damage by disease and insect to conventional pesticide, the frequency of utilization of agricultural chemicals improves, and dosage increases, and agricultural chemicals residual on the fruit is on the increase.Though the edible part of watermelon is its melon pulp, because fruit surface receives pesticide pollution, agricultural chemicals is inner through epidermis infiltration melon pulp, so that causes that the edible safety of watermelon more and more is a problem on the market.
Summary of the invention
The purpose of this invention is to provide a kind of method that prevents the infringement of watermelon fruit pesticide pollution and sick worm, to solve the pollution that the watermelon fruit is vulnerable to spray insecticide at expanding stage and the problem of various sick worm infringements.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
Earlier polyvinyl alcohol pellet being put into boiling water in 10% ratio stirs; After off-bottom; It added in 35～40 ℃ the warm water stir, finally be mixed with concentration and be 2%, temperature is not higher than 50 ℃ poly-vinyl alcohol solution, this solution is packed in the sprayer while hot; The protection nozzle that will be the horn mouth shape again is fixed on the nozzle of sprayer band elbow, carries out disposable even spraying facing to just thanking to colored watermelon fruit.
Adopt such scheme can receive following remarkable result:
1, can on the watermelon fruit surface, form protective filmy layer after the poly-vinyl alcohol solution spraying, although this layer protecting film is very thin, since the shielding action of this tunic, the pollution of having avoided the watermelon fruit when prevention and elimination of disease and pests, to be sprayed insecticide.Though the growth rate of tender melon is very fast; But because polyvinyl alcohol film has good toughness and ductility; Can adapt with it, though the polyvinyl alcohol water soluble only limits to the hot water more than 80 ℃; In water, only occur swelling under the normal temperature and but do not dissolve, so do not worry after the film forming being drenched by rainwater.Through repetition test, avoid pesticide pollution as long as after once spraying, just can guarantee the watermelon fruit.
2, because the protective action of polyvinyl alcohol film; Can prevent that the watermelon fruit from receiving the infringement of bacteriums such as watermelon eqpidemic disease, anthracnose, bacterial angular leaf spot and melon thin,tough silk snout moth's larva, palm thrips, red ridge chinch bug, insect at expanding stage; Reduced applications of pesticide amount, high-quality for producing, non-harmful watermelon has been created advantage.
3, polyvinyl alcohol is one of safest plastics.The present U.S., Japan all approved use it for food and pharmaceuticals industry, and the present invention only is applied to this known food melon pulp of watermelon, does not eat on the melon kind of melon skin, so, can not eaten by mistake after not worrying plucking.
Embodiment
Below in conjunction with embodiment the present invention is done further description:
Earlier polyvinyl alcohol pellet being put into boiling water in 10% ratio stirs; After off-bottom, it added in 35～40 ℃ the warm water stir, finally be mixed with concentration and be 2%, temperature is not higher than 50 ℃ poly-vinyl alcohol solution; This solution is packed in the sprayer while hot; The protection nozzle (use during general spray herbicide, the agricultural chemicals shop is on sale) that will be the horn mouth shape again is fixed on the nozzle of sprayer band elbow, carries out disposable even spraying facing to just thanking to colored watermelon fruit.
