Pollution-free disinfestation method for fruit plant

Abstract

The invention discloses a nuisance free disinsection method for fruit tree, comprising the following steps: the first step: preparing kalium hypermanganicum solution water 200-300 units and kalium hypermanganicum 0.2-0.3 units according to weight unit; the second step: spraying the kalium hypermanganicum solution from the tree top to bottom on the branch and trunk when the outer temperature lower than -4 Deg C, taking the branch being wet as normal; the third step: digging the soil for depth of 10-15m around the tree root area with a diameter of 30-40m, then spraying the solution prepared in the first step into the hole, to make the surface be wet, closing the hole when the water freezing. The killing rate of adult pest is above 90%, and the spraying fruit tree without pesticides not only prevents the farmer from being toxic in body and skin, avoids the environmental pollution, but also reduces the production cost for farmer and guarantees the food safe for consumer, so the method possesses great economic and social benefit.

Description

Technical field [0001] The present invention relates to a method for pest control of fruit trees, in particular to a method for pest-free pest control of fruit trees. Background technique [0002] Drupe fruit trees such as peaches, plums, apricots, cherries, pomegranates, etc., due to the infestation of pests, will reduce or kill fruit trees, causing fruit farmers to suffer great losses. In particular, aphids, hawthorn red spiders, mulberry scales, and scale insects are the most harmful to fruit trees. For example, aphids can reproduce for 30-50 generations each year. From October to November, they can reproduce in fruit branches, flower buds, main buds, Eggs are laid between the cracks in the main trunk, and they will hatch into aphids in the next spring, which will directly harm the flowers, fruits and leaves of fruit trees. After May Day, the aphids will grow wings and fly onto various vegetables to continue to harm the vegetables. They fly back to the fruit trees to lay their...

[0002] Drupe fruit trees such as peaches, plums, apricots, cherries, pomegranates, etc., due to the infestation of pests, will cause fruit trees to reduce or stop production, causing great losses to fruit farmers

In particular, aphids, hawthorn red spiders, mulberry scales, and scale insects, which are in the majority, are the most harmful to fruit trees. For example, aphids can reproduce 30-50 generations per year. From October to November, fruit tree branches, flower buds, main buds, Eggs are laid between the cracks in the main trunk, and they hatch into aphids in the next spring, directly harming the flowers, fruits, and leaves of fruit trees; after May 1st, the aphids grow wings and fly to various vegetables to continue to harm vegetables, until around the 11th It flies back to the fruit tree to lay eggs, repeating itself again and again, and it is extremely difficult to eliminate; another example is the hawthorn spider mite, also known as the hawthorn spider mite, which occurs all over the country, mainly adult mites, nymphs, and early mites suck the leaves of fruit trees. In an environment above 24°C, a generation is produced every four days, which can cause no flower buds in the current year and no production in the next year; the mulberry scale insects and scale insects mainly damage the branches of fruit trees, and in severe cases can cause half-dead fruit trees in the entire orchard, causing losses to fruit farmers. heavy

For the insect pests of fruit trees, the past practice is to spray pesticides on fruit trees in spring and summer, and use pesticides to kill these pests, but using pesticides to kill insects will cause huge pollution to the environment. acute and chronic poisoning; the use of pesticides pollutes rivers and the atmosphere; what’s more, pesticides can easily cause skin cancer, lung cancer, nose cancer, etc.; Conducive to the sustainable control of pests
