Abstract

The invention discloses a Hebei pear tree pear psylla damage controlling method. The method specifically comprises agricultural control, artificial physical control, biological control and chemical control. During pear psylla first generation and third generation nymph occurrence stages, a pesticide A is used for carrying out comprehensive spraying twice upon the entire Hehei pear tree. During a pear psylla second generation occurrence stage, a pesticide B is used for carrying out comprehensive spraying twice upon the entire Hehei pear tree. Freezing water is irrigated twice in late autumn, such that a thin layer of ice is formed on the ground, and overwintering adult pests are died from drowning and freezing. Bark is scraped in early spring and later autumn, and parasitic wasps and ladybugs are protected and utilized. A leaf picking treatment is carried out, such that pear psylla damage is greatly reduced. According to different growth conditions of Hebei pear tree pear psylla, different pesticides are used during different pear psylla occurrence stages, such that the method is more targeted, and the pesticidal effect is significant. Raw materials harmless to human bodies are used, such that damage to human bodies caused by harmful substance residue can be effectively prevented.

Description

A kind of prevention and controls of pear tree pear sucker insect pest

Technical field

The invention belongs to planting fruit trees technical field, the prevention and controls of a kind of pear tree pear sucker insect pest.

Background technology

Pear kind tree vigo(u)r is healthy and strong, and the inside washiness is the sweetest, bark taupe, annual shoot yellowish-brown, perennial branch Bronzing, becomes branch rate low；The wide oval of blade, the tapering or prominent point of tip, basal circular or extensively circular, fruit good looking appearance, pears Stalk portion projection, shape is like Caput Anas domestica；Late September to early October gathers in the crops, just in yellow green, and unique flavor, nutritious；Main feature Being big in fruit, general single fruit weight 175 grams, the maximum 400 grams, the thin core of skin is little, and juice is many without slag, and sour-sweet moderate, delicate fragrance is long, crisp And oiliness, have the title of " born manna "；Include the mineral such as abundant vitamin C and calcium, phosphorus, ferrum, in vitamin B family Great history book；It is up to more than 12% containing flow vector, can preservation and freshness 5-6 month.Have clearing away heart-fire and moistening the lung, relieving cough and asthma, dry convenient, Promoting the production of body fluid to quench thirst, effect of relieving alcoholic intoxication removing toxic substances.

In pear tree tree growth course, pear sucker insect pest extremely seriously, thus causes the yield of pears to reduce, Quality Down； For a long time, China has been used up chemical pesticide to the preventing and treating of insect pest of the fruit tree, and it is residual that these pesticide have in various degree on fruit Stay, toxin can be accumulated in vivo after people are edible, endanger healthy, ultimately result in the generation of disease；Therefore invention one is cased with Effect and the pest control integrated management measure of green, be current problem demanding prompt solution.

Summary of the invention

For the problems referred to above, it is desirable to provide the prevention and controls of a kind of pear tree pear sucker insect pest, to pear wood mite Evil preventing and treating is comprehensively, it is possible to be effectively improved the mortality rate of pear sucker, reduces egg production capacity, it is possible to be prevented effectively from pear sucker insect pest again Raw.

The present invention is achieved through the following technical solutions:

A kind of prevention and controls of pear tree pear sucker insect pest, concrete includes:

(1) cultural control: at early spring and Qiu Mo, carries out orchard cleaning, scrapes bark and combines basal dressing, and water two is frozen in the filling of autumn end Secondary, it is 7 days that the aqueous phase interval is frozen in twice filling, for the first time irrigation quantity be moisture penetration to soil 8-10cm, irrigation quantity is for the second time Moisture penetration is to soil 16-18cm；

(2) artificial physics preventing and treating: at the end of May, pear sucker 2nd generation nymph, concentrate the time of 2 days, to pear tree tree head, the back of the body Upper, the most dormant young sprout in peripheral position plucks the part that top 7-9 sheet leaf is not deployed, and the most buried；

(3) Biological control: in mid-June, the natural enemy parasitic wasp of Sustainable use pear sucker, ladybug, Chrysopa；

(4) chemical prevention: in the pear sucker 1st generation nymph emergence period, uses insecticide A to be watered 330-340 times and is diluted, to whole Pear tree carries out twice spraying comprehensively, and twice interval time is 10 days；In the pear sucker 2nd generation nymph emergence period, use parasite killing Agent B is watered 460-470 times and is diluted, and carries out twice spraying to whole pear tree comprehensively, and twice interval time is 8 days；At pears Wood louse the 3rd nymph emergence period in generation, use insecticide A to be watered 380-390 times and be diluted, whole pear tree is carried out the most comprehensive Spray；
