Abstract

The invention discloses a method for repelling maladera orientalis motschulsky in orchards, which includes the following steps: (1) wheat seeds are first sowed in a divided orchard in the autumn of the first year; (2) in the spring of the second year, fruit seedlings are transplanted into a wheat field; (3) after ripened, the wheat needs to be harvested in time, and then wheat seeds are sowed again in autumn; (4) after fruit trees are transplanted for 2 to 4 years, wheat can be interplanted in line spacings by both sides of the fruit trees, the interplanting range needs to be 50 percent to 60 percent of the line spacing, and thereby maladera orientalis motschulsky can be repelled. By utilizing the biological nature of wheat that wheat can effectively repel maladera orientalis motschulsky, the method effectively overcomes the defects existing in conventional control methods, such as poor control effect and time and labor waste; since the price of wheat seeds is low, the control cost of the method is low as well; and moreover, the method also can add wheat income to the orchard, and prevents the easy production of chemical residue by conventional chemical control.

Description

Walk quickly and keep away the method for Maladera orientalis in a kind of orchard

Technical field

The present invention relates to the pest control field, be specifically related to walk quickly and keep away in a kind of orchard the method for Maladera orientalis.

Background technology

Maladera orientalis is a kind of in Chinese apple, peach, pears insect, biologically be divided under Insecta coleoptera Melolonthidae, be distributed widely in the most of China region, main harm rose family fruit tree, persimmon, grape, mulberry, poplar, willow, elm, the sections more than 40 such as various crops and Cruciferae are 150 Plants approximately, especially spring, the lighter caused blade incomplete with the adult fruit tree young leaflet tablet of causing harm, and photosynthetic production capacity descends; The full leaf sheet of severe one is eaten up, and only stays petiole, has a strong impact on the growth of fruit tree, thereby further affects bear fruit quantity and the total quality of fruiting period, and serious even can have no harvest.

In order to solve the harm of Maladera orientalis, the method for preventing and treating of control is mainly by the artificial control at present, and the mode that cultural control and chemical control combine realizes; The artificial control, mainly to utilize adult tool become light and seemingly-dead habit, adopt black light lamps or shake to set and catch and kill in the adult emergence period, although this kind method of preventing and treating can be controlled the quantity of Maladera orientalis in a short period of time, thereby reduce its harm to fruit tree, but the place that but can't tackle the problem at its root, and large-area layout black light lamp has not only increased artificial control's cost to a large extent, and also need to draw special line, trouble very; And that the tree that shakes is catched and killed operator's physical fitness requirement is larger, and whole labour intensity is larger, and the effect that obtains is also comparatively limited.

Cultural control, open up wasteland and cultivate ground, destroys grub living environment; The crop rotation of pouring water, eliminate young larva, catches the adult that emerges.Rice field-upland field rotation can prevent and treat larva harm; In conjunction with intertill and clean tillage, remove the limit, field, the weir weeds, the dark rake of summer public land piece deep ploughing; Especially optimum period, carried out autumn ploughing and spring ploughing when larva (or claiming grub) is movable in surface soil layer, and deep ploughing is larva picking simultaneously, does not use the compost made of stalks that becomes thoroughly decomposed in end; Although this kind method can be in certain zone the realization purpose that Maladera orientalis is killed in short-term, and remove satisfactory for result, but can break out Maladera orientalis the coming year again, and this kind method is only suitable for first whole before fruit growing, the place that can't tackle the problem at its root.

Chemical control, adopt to throw and raise poison bait, adopts chemical agent spray soil, makes large-scale pesticide-clay mixture; Although this kind method can be killed Maladera orientalis thoroughly, its a large amount of noxious materials that stockpile in soil can gather thereupon in fruit, give eater's the healthy hidden danger of having brought; And throw the poison bait raise also easily by some beneficial birds or other non-object animal edibles, thereby easily cause Large Scale Death to cause the unbalance of whole biological chain.

Summary of the invention

The object of the invention is to provide a kind of walk quickly and keep away Maladera orientalis in orchard method, and it can solve existing problem in background technology effectively.

Walk quickly and keep away the method for Maladera orientalis in a kind of orchard, it comprises following steps: (1) selects at first to sow in ready-portioned orchard wheat the autumn of First Year; (2) treat that Second Year is transplanted into fruit tree seedlings in wheat paddock spring; (3) should, with its timely harvesting, then again continue in the fall kind of upper wheat wheat seeds after the wheat maturation; (4) transplant between 2-4 when fruit tree, can be in the both sides of fruit tree intercropping wheat in the ranks, the intercropping amplitude should be at the 50%-60% of line space, thereby realizes walking quickly and keeping away the purpose of Maladera orientalis.

Owing to having adopted above technical scheme, the present invention has following beneficial effect: by utilizing wheat, can effectively walk quickly and keep away the biological nature of Maladera orientalis, overcome effectively that tradition is prevented and treated the existing anti-heterodyne of method, the drawback such as waste time and energy, because the price of Wheat Species is lower, therefore its cost accounting is also comparatively cheap, and can also increase the income of a wheat in orchard, stop simultaneously the medicament residue of the easy generation of traditional chemical control.

Embodiment

For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below will the technical scheme in the embodiment of the present invention be clearly and completely described.

Embodiment 1

Collect 30 Maladera orientalis, every 10 are divided into an experiment group, amount to 3 groups; There are in the orchard of wheat three places arbitrarily let fly away in intercropping 3 groups of Maladera orientalis, and tracing observation its take food and active situation, the Maladera orientalis that drops on wheat does not take food wheat, but flown away from soon wheatland, also do not observe from the ground wheat and fly to phenomenon on fruit tree, visible wheat has very strong avoidance effect to Maladera orientalis.

Embodiment 2

Collecting 25 Maladera orientalis puts in an airtight container, and then at this container, sneak into apple leaf, leaf of pear tree, Folium Crataegi, wheat seedling leaf and From Strawberry Leaves, take out the situation that takes food of observing after 24 hours, apple leaf, leaf of pear tree and Folium Crataegi are all gnawed, and wheat seedling leaf and From Strawberry Leaves are not gnawed, as seen in the free choice feeding process, wheat seedling leaf and From Strawberry Leaves can have very strong avoidance effect to Maladera orientalis.

Embodiment 3

Collect 30 Maladera orientalis and make its hungry 48 hours; Then produce the experimental provision of a H type structure, the two ends of this experimental provision are two independently closed containers, are connected with a siphunculus that communicates with two closed containers in the middle of it, and the middle part of this siphunculus is provided with input port; Drop into the wheat seedling leaf in two closed containers on one side, another side drops into apple leaf, leaf of pear tree and Folium Crataegi; Then will put into from input port in siphunculus through the Maladera orientalis of hungry 48 hours, and observe the trend of Maladera orientalis, the Maladera orientalis that enters into siphunculus all enters into and drops into the closed container that apple leaf, leaf of pear tree and Folium Crataegi are arranged; This shows, the wheat seedling leaf still has good avoidance effect to Maladera orientalis.
