The method is characterized in that due to the fact that the distance between a furrow opener of a seeder and a fertilizer applying device of the seeder is increased to be 10 cm, the straw scattered on the seeding lines can be separated to the two sides of seeding furrows, straw accumulation does not exist on the seeding lines after corn seedlings emerge, the environment suitable for the Athetis lepigone to inhabit to do harm is not formed, and the prevention effect can be higher than 90%; in addition, the later-period prevention and control labor intensity and the later-period prevention and control economic input are greatly reduced, meanwhile, mechanical operation is achieved, and the method is suitable for large area use; the efficient and nuisanceless prevention aim is achieved; under the condition that at present, the field wheat straw is not advocated to be removed, or turnover plowing after wheat harvesting is not advocated, the method is worthy of popularization and application.
Description
Technical field
The present invention relates to a kind of agricultural insect management method, particularly relate to the method that adopts 2 committee noctuids of the clean sowing of mechanization large area row wheat straw control.
Background technology
2 committee noctuid [
athetis lepigone(M schler, 1860)] be the de novo a kind of pest in China's summer corn producing region.Domesticly find 2 committee's noctuids harm summer corn seedlings in Shijiazhuang Region, Hebei Province early than in July, 2005, bore moth basal part of stem, cause the withered heart of seedling to be wilted dead, or bite corn root broken, cause lodging, cause the serious disconnected ridge that is short of seedling, within 2010, this worm generally occurs in farmland productivity in south-center of Hebei Province summer corn district, 2011 in Hebei, the province such as Henan, Shandong, Shanxi, Anhui, Jiangsu breaks out, there is area and exceed 3,000 ten thousand mu, minority plot is reseeded or is ruined kind, is rare serious insect pest in Maize Production in recent years.
It is reported, 2 committee noctuid adults are liked covering the activity of moist place and laying eggs, and larva is also liked covering the activity of moist place damage to crops seedling.Especially the sowing row harm that has wheat straw to cover is serious, and what a strain maize seedling around had reaches 20 larvas.After last century Mo harvesting wheat, remove or crop straw burning, or plough behind soil seeding corn again, field does not possess the suitable environment of 2 committee noctuids.But in recent years, Huang-Huai-Hai summer corn producing region had generally been promoted wheat stalk returning, summer corn and had been pasted stubble sowing etc., these techniques save farming spending, shorten the time in busy farming season, improve farming efficiency, freed large quantities of labours, the environmental pollution of also having avoided crop straw burning to cause.The can yet be regarded as great technological change of agricultural production.But simultaneously a large amount of wheat stalks are directly scattering into the field of seeding corn, for the harm corn that breaks out of 2 committee noctuids provides the suitable environment that large area is favourable.
Therefore by rationally disposing field wheat straw, the suitable environment of 2 committee's exigua larvaes of artificial destruction, can reach and alleviate or control the object that 2 noctuids of entrusting are caused harm.Produce at present upper suggestion before summer corn is after planting emerged, manually by residual capable corn seeding residual wheat body with rake an animal-drawn seed plough cleaning to wheat stubble in the ranks.But the method is time-consuming, under the prerequisite of, labor cost sustainable growth in short supply in human resources, be difficult to spread.Therefore mass peasants are badly in need of a kind of method that can also remove sowing row wheat straw in sowing.But the conventional planting with sowing machine device using and the distance of plough are generally 0 centimetre at present, also i.e. sowing is with fertilising in same position, and just fertilising is deeper than sowing, can reduce like this power of tractor.But, then produce and often occur that fertilizer contact with seed and occur the fertile seedling phenomenon of burning, for this reason, in some local sowing, by seeder and fertilizer applicator horizontal position adjustment 0-5 centimetre, make to apply fertilizer below seed oblique, reduce fertile burning seedling phenomenon.However, ditch also too narrow, a large amount of wheat straws that after planting pile up on both sides set back again and cover sowing row, do not possess the function of removing sowing row wheat straw.Object of the present invention is exactly in sowing, provides a kind of mechanization to remove the method for sowing row wheat straw, thereby realizes the object of saving of work and time, large area, 2 committee's noctuid insect pests of efficient prevention and control.
Summary of the invention
The object of the invention is can not reach for current conventional seed planting the object of removing sowing row wheat straw, and the method for 2 committee noctuids of artificial removing sowing row wheat straw prevention and control is time-consuming before employing emergence of corn, shortcoming that can not spread, when a kind of sowing is provided, can mechanization remove the method for sowing row wheat straw, specifically can realize by following steps:
Adjustment sower arranges: the horizontal range of the seeder of sower and plough is adjusted to 10 centimetres;
Cleaning wheat straw: increased the width of sowing row trench digging after adjusting, the residual residual body of wheat straw of sowing row can be separated to seed furrow both sides in summer corn sowing;
Preferred: if existing after harvesting wheat, wheat straw is pulverized, then sowed according to above-mentioned, clean sowing row wheat straw effect is better, and 2 committee's noctuid effects of prevention and control are also better.
The invention has the beneficial effects as follows: this prevents and treats method saving of work and time suitable spread; Mechanical method is simple to operation, and effect stability has sustainability, has realized economic, efficient, the non-harmful object of preventing and treating; , cost in short supply current labour continues to increase, and do not advocate and remove the residual body of field wheat, or in the situation of ploughing after harvesting wheat, the present invention program is suitable for large area applications.
Embodiment
In order to make those skilled in the art person understand better the present invention, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with specific embodiment, the present invention is further detailed explanation.

From last century end, China widelys popularize wheat stalk returning, no-till maize, make to be covered with between corn field the harm that breaks out that a large amount of wheat stalks causes 2 committee noctuids,, labour cost in short supply current labour continues to increase, the artificial wheat straw of removing is difficult to spread, and can not advocate large-area clean rural area and plough in the situation in soil, according to the habit of 2 committee noctuids, while taking to sow, machinery separates sowing row wheat stalk, method is simple, saving of work and time, economical and efficient, can reach the object of 2 committee noctuids of good prevention and control.In the time implementing this technology, owing to having increased the width of trench digging, often need the tractor-drawn sower better effects if of larger horsepower.
Embodiment 2:
Within 2013, carry out in Hao Zhuan village, booth western entrance town, Xingtai City Pingxiang County, summer corn experimental cultivar is Jifeng 223; Test plot is loam, more than middle fertility.Sowing on June 16, existing by the pulverizing of wheat wheat straw, then carry out mechanization by test requirements document and remove the test of sowing row wheat straw.
Test following 3 processing altogether:
A. the seeder of sower and fertilizer applicator spacing are adjusted to 10 cm widths;
B. 5 centimetres of planting with sowing machine device and fertilizer applicator spacing;
C. 0 centimetre of planting with sowing machine device and fertilizer applicator spacing.
Every community 200m
2, every processing in triplicate.
Control time and method: with embodiment 1.
Results and analysis:
As can be seen from Table 2, the A of the seeder of 10 centimetres and plough width processes and can reach 93.72% to the preventive effect of 2 committee noctuids, and seed furrow width can reach 7 centimetres, and wheat straw is separated to sowing row both sides better.And other two kinds conventional width settings are owing to the wheat straw of sowing row can not being separated to seed furrow both sides completely, later stage wheat straw is still deposited in around maize seedling, cause 2 committee's exigua larvaes to be got around seedling and assemble harm, the later stage, killed strain rate was all processed higher than A extremely significantly.Meanwhile, also explanation is existing pulverizes wheat wheat straw, and then it is better to sow clean sowing row wheat straw effect.
Table 2: different sowers arrange 2 committee's noctuid control efficiency (2013, Pingxiang, Hebei)
| Test is processed | Seed furrow (between wheat straw) width (centimetre) | Total strain number (strain) | Killed strain number (strain) | Killed strain rate (%) | Preventive effect (%) |
| A | 7 | 1410.67 | 21.00 | 1.49Aa | 93.72 |
| B | 3 | 1423.67 | 250.33 | 17.58Bb | 25.92 |
