Abstract

The present invention relates to a kind of fig of killing to survive the winter the method for roundheaded borer, this detailed process is: step a, in spring, before fig twig sprouts, wipes out all overground part branches, kills longicorn insect in branch; Step b, uses general farmland-use water, and orchard soil and fig stub are all immersed in water, and then get rid of orchard ponding, then the roundheaded borer of surviving the winter colonized in fig root and limb all can be suffocated and kill.The present invention adopts artificial removing and physical smother play deinsectization, can not use chemical pesticide completely, thus, have environmental protection and simple and easy to do advantage.

Description

A kind of fig of killing is survived the winter the method for roundheaded borer

Technical field

The present invention relates to plant protection art, particularly relate to a kind of fig of killing and to survive the winter the method for roundheaded borer.

Background technology

Fig (FicuscaricaL.) is fallen leaves to warm temperate zone orchard fruit in a kind of perennial subtropics.Under field conditions (factors), it can grow up to the high megaphanerophyte of 5-8 rice, and under artificial intensive cultivation condition, fig height of tree general control is within 2 meters.The growth result characteristic of fig is different from general fruit tree.Its bud is divided into two kinds, and a kind of is differentiation in autumn the previous year, is usually distributed in shoot apex.Along with spring temperature rises, these buds are grown gradually, and ripe in 6-7 month then, i.e. so-called " summer fruit ".The second bud is starting differentiation spring then.Along with Folium Fici bud is sprouted and young sprout growth, from young sprout base portion 3-5 saves position, break up gradually in axil, form bud then.The fruit formed after these flower bud developments, at 8-10 then monthpart is ripe.I.e. so-called " autumn fruit ".Thus, fig yields positive results in all fruit trees to be easy to one of seeds the most.Sometimes, the branch middle and upper part of cuttage then also can form a large amount of fruits.

In fig process of growth, disease is almost seldom had to occur, so it is do not need to spray bactericide that fig is produced.But fig limb is easily subject to longicorn and causes harm.Wherein, more than 90% is mulberry longicorn, also has a small amount of longicorn beetle.In the general time, the longicorn strain rate that causes harm is about 15%, and time serious, worm strain rate reaches more than 90%.On a branch, longicorn channel is usually more than 2, and maximum reaches 8 ~ 10.Bore the fig tree of moth through longicorn, the lighter's tree vigo(u)r weakens, and branch is easy to break, and the whole strain of severe one is dead, has a strong impact on fig output.Thus, longicorn is caused harm becomes one of main problem of hindering fig production development.

Fig longicorn generally survives the winter in tree body limb and root burrow with the form of larva.A life cycle is 3 years.Its adult started to occur in late May, and July is the peak period that adult occurs and lays eggs, and after August, adult reduces gradually.Every female adult pest can lay eggs more than 100 all one's life.First sting food spray before laying eggs or gnaw bark.Longicorn ovum often produces above sprig bifurcated, and there is significantly " river " shape cutting at place of laying eggs.Ovum becomes larva through hatching in two weeks.Newly hatched larvae first upwards eats into food about 1cm along phloem, then reverses end for end to eat into food 1 ~ 4cm downwards along phloem.Portion's epidermis of being now injured caves in, and becomes pitchy.Later larva eat into downwards gradually into, gnaw xylem organization, and in burrow, outwards sting out a circular porus excretorius at a certain distance, with defecate.Longicorn worm excrement bronzing, wood chip shape.According to up-to-date defecation hole, the approximate location of roundheaded borer in limb can be judged.The roundheaded borer at 1 age is eaten into downwards into 20 ~ 30cm in fig branch, and during 2 age, larva continues moth food 30 ~ 50cm downwards, and what have can reach root deeply.3 age mature larvas, after root or nearly root are survived the winter, move along on burrow in spring, and cross 1 ~ 3 defecation hole, first sting out blank emergence hole road at certain position, diameter 1 ~ 1.5cm, does not gnaw through, and only stay epidermis or break by the teeth and to cover with wood fragments bits.From the appearance, bark is outstanding slightly herein, has thick wood wool to expose, and often has yellowish-brown resin or rotten soiling solution to flow out afterwards especially overcast and rainy.After blank emergence hole is stung into, mature larva is got back to again in burrow, and below emergence hole, 2 ~ 5cm place wood chip bitten away surrounds pupa room, and upwards, prepare cave of pupating is adult to larva head.

As can be seen here, fig longicorn is except egg-laying period and adult stage are exposed to, and whole larval phase all parasitizes among limb, is generally difficult to directly kill.

Thus, elimination roundheaded borer becomes the important safeguard measure in fig planting technology.

In view of the foregoing, creator of the present invention obtains this creation finally through long research and practice.

Summary of the invention

A kind of fig of killing is the object of the present invention is to provide to survive the winter the method for roundheaded borer, in order to overcome the technological deficiency that longicorn is difficult to directly kill.

For achieving the above object, the invention provides a kind of fig of killing and to survive the winter the method for roundheaded borer, this detailed process is:

Step a, in spring, before fig twig sprouts, wipes out overground part branch near the ground, kills longicorn insect in branch;

Step b, uses general farmland-use water, and orchard soil and fig stub are all immersed in water, and then get rid of orchard ponding, then the roundheaded borer of surviving the winter colonized in fig root and limb all can be suffocated and kill.

Further, in above-mentioned steps a, only stay about 10cm stub, then pulverize branch with plant cracker.

Further, in above-mentioned steps b, adopt river, pool water or running water is vexed floods 12-24 hour.

Beneficial effect of the present invention is compared with prior art: the present invention adopts artificial removing and physical smother play deinsectization, can not use chemical pesticide completely, thus, have environmental protection and simple and easy to do advantage.

Embodiment

Below, to above-mentioned being described in more detail with other technical characteristic and advantage of the present invention.

The present invention kills the survive the winter main process of method of roundheaded borer of fig:

Step a, in spring, before fig twig sprouts, wipes out all overground part branches near the ground, only stays about 10cm stub, then pulverizes branch with plant cracker, kills longicorn insect in branch.Pulverized fig branch can be used as the culture matrix of Edible Fungi.

Step b, uses general farmland-use water, as vexedly in river, pool water or running water etc. floods, orchard soil and fig stub are all immersed in water, keep 12-24 hour, then get rid of orchard ponding, then the roundheaded borer of surviving the winter colonized in fig root and limb all can be suffocated and be killed.

The present invention adopts artificial removing and physical smother play deinsectization, can not use chemical pesticide completely, thus, have environmental protection and simple and easy to do advantage.

Illustrate below by specific experiment:

On April 19th, 2014, in the herd-boy village Sheng Wang fruits and vegetables Co., Ltd of Xinbei district, Jiangsu Province, select 15 years raw 40 mu, fig gardens, spacing in the rows 50cm, line-spacing 3m, long stripped planting, ridge height 50cm, ridge height 80cm.Before submerging treatment, fig tree overground part branch is stayed 10cm stump.Then the water in neighbouring irrigation canal is evacuated in fig garden.At 11 in the morning starts to draw water, 6 end at dusk.6 beginning drainings in morning next day, 12 water are put dry.After orchard soil is dry and comfortable, the roundheaded borer in investigation fig limb, the larva finding that there is worm channel place is all dead, proves that the method can kill longicorn Overwintering Larvae.

The foregoing is only preferred embodiment of the present invention, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that invention claim limits to it, amendment, even equivalence, but all will fall within the scope of protection of the present invention.
