Abstract
The invention belongs to a crop protection technology, in particular relates to a method for protecting crop seedlings against damages from subterranean insects by adopts a barrier method. The subterranean insects bite radicles or caulicles of crops to cause death of seedlings. In the prior art, chemical controlling is adopted to kill the subterranean insects to protect the plant seedlings with the defects of poor control effect and pollution to soil environments. The method for protecting crop seedlings against damages from subterranean insects by the barrier method comprises the following steps of: preparing a barrier device; digging planting holes in field; watering; applying carbofuran insecticide into soil according to a traditional method and dosage; carrying out spaced sowing and seedling culture on seeds and inserting one end of the plastic cylindrical barrier device in soil around seeds; and covering earth on the outer side of the plastic cylinder to keep flush with the soil in field, wherein the upper end of the plastic cylinder is 50mm higher than the soil surface. The invention has the advantages of simple method, easy operation, low barrier device cost, repeated using, reduced chemical pesticide consumption, reduced environment pollution, solid control on the ground and under the ground and good control effect.
Description
Technical field
The invention belongs to the crops plant protection technology, the method for specifically a kind of Barrier method control soil insect damage to crops seedling.
Background technology
Soil insect is the formidable enemy of crops, and it gnaws the root system of crop seedling, bites the ground children stem of crop broken, makes seedling death, causes the crop disconnected ridge that is short of seedling, crop production reduction.During the research of dry crop breeding of new varieties, by crop parent or new varieties seed that various researchs and experiment obtain, mostly quantity is few.Sometimes can only obtain several seeds, extremely precious, if suffer the infringement of soil insect, can the cultivation of new varieties be caused an immeasurable loss.Therefore in scientific research with introduce a fine variety in the work, it is the crucial thing of part that the cover crop seedling is not subjected to the harm of soil insect.The soil insect of crops seedling phase has cutworm, wireworm and grub.Use the kind clothing agent of desinsection during sowing or around seed, use soil insecticide can kill seed soil insect on every side effectively, stop insect in soil, to be moved to seedling.But to from insecticide distance cutworm far away, hide daytime in agricultural land soil, get out ground night and move and look for food, the effect of chemicals treatment is unsatisfactory.If take comprehensive soil chemoprevention, not only increase cost, also increase the weight of soil pollution.
When taking anti-on the ground therapy control cutworm, have only and just poison after cutworm is eaten poisonous seedling by the time and dead, so this method protects seedling also undesirable.
Prior art adopts chemical control to kill soil insect protective plant seedling, and its shortcoming is:
1, control efficiency is poor, can not effectively protect seedling;
2, chemical pesticide pollutes soil environment.
In view of existing chemical protection method protective plant seedling fully and effectively; so invent a kind of method of utilizing physical barriers to combine with chemical control; seedling and soil insect are isolated, thereby the method that a spot of precious seed seedling in the crop breeding is shielded is crucial.
Summary of the invention
The objective of the invention is: a kind of method of utilizing physical barriers to combine with chemical protection is provided, seedling and soil insect are kept apart, thus the method that a spot of precious seed seedling in the crop breeding is shielded.
The object of the present invention is achieved like this:
The method of a kind of Barrier method control soil insect damage to crops seedling is as follows:
(1) preparation barrier device: get 0.3 millimeter of wall thickness, diameter 50-80 millimeter, the identical plastic barrel of diameter up and down, the penetrating cylinder in two ends that is cut into 80-100 millimeters of height is standby;
(2) barrier setting:
A digs in the field sowing cave, waters in the cave, applies insecticide;
B broadcasts seed in the cave;
C inserts the seed surrounding soil with an end of plastic cylinder;
D inserts fine earth and covers seed in plastic cylinder;
E is extremely equal with field soil at the outside of plastic cylinder earthing;
The upper end of f plastic cylinder is higher than 50 millimeters on the face of land;
Insecticide described in the step (2) is the soil insect insecticide.
Main points of the present invention are methods of utilizing physical barriers and chemical protection to combine, the protective plant seedling.Soil application soil insect insecticide, the under ground portion of protection seedling utilizes plastic cylinder as barrier simultaneously, and plant seedlings and seedling surrounding soil are kept apart, and makes soil insect all can't encroach on plant seedlings from soil to ground, has realized purpose of the present invention.
During the invention process, leave earlier the sowing cave, water, sow, apply the insecticide carbofuran of soil insect or phoxim etc., seed is placed in the cave in the field; The plastic cylinder for preparing is stood in the sowing cave, seed is placed in the plastic cylinder, at the inside and outside earthing of plastic cylinder to Horizon; The upper end of plastic cylinder is higher than about the 5cm of the face of land, by the soil fixation plastic cylinder around the tight plastic cylinder.The plastic cylinder that is enclosed within around the crop seedling is smooth firm, and soil insects such as cutworm can not penetrate, and also can't climb up and over, and has constituted three-dimensional effective insect protected barrier jointly with underground insecticide.
Note following details during the invention process:
Choose plastic barrel of the water white no end, be convenient to printing opacity, be beneficial to growth of seedling; Plastic cylinder should be higher than about the outer ground 5cm of tube, in case cutworm is climbed up and over; Soil around the plastic cylinder will be by tightly, in case be blown away.Growth of seedling removes plastic cylinder to not being afraid of cutworm when harm, collects and preserves, and can use continuously several years.In time collect " white pollution " that plastic cylinder also can prevent soil simultaneously, the protection soil environment.
The insecticide that the present invention uses is existing soil insect insecticide, and using method and dosage are existing known technology.Mainly be to be used for killing seedling vicinity cutworm, wireworm and grub, and stop soil insect to be moved, play the effect of double insurance to root.
It is remarkable that the inventive method cover crop seedling avoids soil insect harm effect, does experiment with corn, compares with soil application carbofuran insecticide, and insect bite rate of the present invention is 0, and contrast reaches 17.6 %.Do experiment with Chinese sorghum, compare with the soil application carbofuran, insect bite rate of the present invention is 0, and contrast reaches 21.3 %; Cotton test compares with the soil application carbofuran, and insect bite rate of the present invention is 0, and contrast reaches 19.6%; With the Gao Dancao test, the soil application carbofuran compares, and insect bite rate of the present invention is 0, and contrast reaches 8.5%.
Creativeness of the present invention is:
Prior art adopts the chemical control method to kill soil insect, and control efficiency is undesirable, has also brought the soil environment pollution simultaneously, and this is a long-term insoluble technical problem.The method control soil insect that the present invention uses physics and chemistry to combine has successfully solved this technical barrier.Enforcement of the present invention can increase the technical guarantee of crop breeding work, improves breeding work efficient, helps the agri-scientific research development of technology.
Advantage of the present invention is:
1. method is simple, processing ease;
2. the barrier device cost is low; Can recycle, can not increase the pollution of soil soil.
3. reduce chemical pesticide and use, reduce environmental pollution;
4. control efficiency is good.
