The technical scheme that the present invention solves above-mentioned technical problem is as follows:Maize planting propagation protection day in a kind of vegetable greenhouse The method for opposing insect, keep the implantation methods of current greenhouse vegetable, vegetables spacing in the rows, line-spacing and density and conventional cultivation method phase Together, it is characterised in that in 500m2Greenhouse inlet at plant 2 row corns, formed 2 row corn belts, in corn plant height 30cm, Accessed on every plant of corn after rhopalosiphum padi or corn leaf aphids 50,5 days and access 2-3 ages Pediobius foveolatus 10 on every plant of corn.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, the spacing in the rows of the corn is 50cm, and the line-spacing of corn is loose for the furrow of vegetables in greenhouse.
Further, the furrow of vegetables are wide in the greenhouse is not less than 60cm.
Further, the corn is sowed for 20 days before vegetable cultivation in greenhouse.
Further, the ladybug is the one or more in harmonia axyridia, coccinella septempunctata, Propylaea japonica.
The beneficial effects of the invention are as follows:
The inventive method has effectively played the effect of predator ladybug in corn self-restraint and protection greenhouse, in greenhouse " Eco-Island " is established, the ecological environment for being advantageous to ladybug propagation is created, promotes natural control of the ladybug to aphid in greenhouse Make and use, and high-stem plant corn is planted at greenhouse inlet, can obstruct insect entrance in the greenhouse outside, the life stage of corn compared with It is long, it is substantially consistent with solanaceous vegetables.
The corn belt that the present invention establishes is advantageous to that proreduplication and Protect natural enemies occurs in insect, before insect is largely broken out Effectively suppress insect, compared with compareing field, natural enemy insect colonizes rate increase 18.5%-20%.Show that this method makes day in greenhouse Enemy effectively colonizes, and reduces the possibility of insect great outburst, obtains significant ecological benefits.This method makes aphid on greenhouse vegetable The worm outbreak period is delayed one week, and peak period Aphed population declines 10%-15%, and Aphed population reduces on average hundred plants of vegetables 14%;Compared with compareing field, it is effectively controlled insect and causes harm, and reduce natural enemy input, reaches good economic benefit.
The replacement food of ladybug provided by the invention is rhopalosiphum padi or corn leaf aphids on corn, they and greenhouse vegetable Upper black peach aphid, cotten aphid etc. are equal, but they will not cause harm vegetables, only a few grass such as feeding corn, wheat.It can increase Grow 3 kinds of Predaceous Coccinellids such as Protect natural enemies harmonia axyridia, coccinella septempunctata or Propylaea japonica.Because these three ladybugs are all euryphagy , wheat aphid, rhopalosiphum padi can be both preyed on, can also prey on the vegetable-crop pest-insects such as black peach aphid, cotten aphid, the selection Preference to aphid does not have The difference of conspicuousness.The corn and vegetable-crop pest-insect such as black peach aphid, cotten aphid can not also cause harm.In chamber planting corn, prevent for producing initial stage Control vegetable aphid release natural enemy, which colonizes, provides place, and post-partum period recovery natural enemy of making a living provides approach.
The present invention can be to the preventative preventing and treating of greenhouse vegetable aphid.The natural enemy that corn belt has conserved can establish population in advance, have The insects such as effect prevention black peach aphid, cotten aphid break out on a large scale, show and delay time to peak and reduction peak value.High-efficiency continuous control effect Fruit.Rate and supplement release nature enemy in amount are colonized due to improving natural enemy, can reach control in a short time and pest control Purpose.Corn is common gramineous crop, easily plants, needs labor management less, and the expense established and maintained is relatively low.

Embodiment
It is described below in conjunction with the principle to the present invention and feature, the given examples are served only to explain the present invention, not uses In restriction the scope of the present invention.
Embodiment 1 justifies the contrast test of maize planting propagation ladybug and pest controlling black peach aphid in eggplant and pimento greenhouse
Tested in the circle eggplant of Pinggu district Beijing Noah organic agriculture company and pimento planting greenhouse.Set Circle eggplant control greenhouse and circle eggplant corn tape handling greenhouse, pimento control greenhouse and pimento corn tape handling greenhouse, each greenhouse are big Small is 500m2, the plant of circle eggplant and pimento is identical with conventional cultivation method away from, line-spacing and density, justify the plant of eggplant away from For 60cm, away from for 40cm, the planting density of circle eggplant and pimento is every row of furrow 2, greenhouse inner circle eggplant and pimento for the plant of pimento Furrow it is wide be not less than 60cm, daily farming operations are carried out using organic vegetable administrative standard, bottoming leaf is once weekly.Using The mode of harmonia axyridia prevention and control black peach aphid.
In circle eggplant corn tape handling greenhouse, 20 days before the plantation of greenhouse inner circle eggplant, it is beautiful to plant 2 rows for porch in greenhouse Rice, the spacing in the rows of corn is 50cm, and the line-spacing of corn is loose for the furrow of greenhouse inner circle eggplant.In corn plant height 30cm, on every plant of corn Access after rhopalosiphum padi 50,5 days and access 2-3 ages Larva Harmonia Axyridis 10 on every plant of corn.
In circle eggplant control greenhouse, circle eggplant is only planted, not maize planting, rhopalosiphum padi and different is also accessed not on corn Color Pediobius foveolatus.
In circle eggplant control greenhouse and circle eggplant corn tape handling greenhouse, circle eggplant is made by oneself plant seedling 1 month after, by harmonia axyridia Quantity with black peach aphid is than 1:10, a 2-3 age Larva Harmonia Axyridis is discharged weekly, it is continuous to discharge 6 times.
In pimento corn tape handling greenhouse, in greenhouse 20 days before pimento plantation, it is beautiful to plant 2 rows for porch in greenhouse Rice, the spacing in the rows of corn is 50cm, and the line-spacing of corn is loose for the furrow of pimento in greenhouse.In corn plant height 30cm, on every plant of corn Access after rhopalosiphum padi 50,5 days and access 2-3 ages Larva Harmonia Axyridis 10 on every plant of corn.
In pimento compares greenhouse, pimento is only planted, not maize planting, rhopalosiphum padi and different is also accessed not on corn Color Pediobius foveolatus.
In pimento compares greenhouse and pimento corn tape handling greenhouse, pimento is made by oneself plant seedling 1 month after, by harmonia axyridia Quantity with black peach aphid is than 1:20, a 2-3 age Larva Harmonia Axyridis is discharged weekly, it is continuous to discharge 6 times.
From after circle eggplant and the field planting of pimento seedling after 7 days, natural enemy harmonia axyridia in investigation control greenhouse and corn tape handling greenhouse And black peach aphid population dynamic, using " " sampling method, 5 points are chosen in greenhouse, randomly select 5 plants of plants, at random at every at 5 points 3, top of plant blade is extracted, black peach aphid and harmonia axyridia population quantity thereon are recorded in observation respectively.Investigate 1 time weekly, data warp After Excel2010 softwares arrange, draw population with SigmaPlot 12.0 and Dynamic Graph occurs.Other results are based on following equation Calculate:Harmonia axyridia colonizes rate=when secondary investigation harmonia axyridia quantity/(when secondary burst size+last time investigation harmonia axyridia quantity); Population quantity rate of change=(the 2nd investigation investigation of quantity-the 1 time quantity)/the 1st investigation quantity * 100%, wherein on the occasion of for Population growth rate, negative value are population depression rate.
Result of the test:
1st, in different disposal greenhouse black peach aphid population dynamic change
Harmonia axyridia can effectively reduce the population quantity of black peach aphid in different disposal greenhouse, control it to develop and endanger, tool Body is presented below:
The black peach aphid peak period in pimento corn tape handling greenhouse is more late 1 week than pimento control greenhouse, and peakedness ratio pimento compares Greenhouse low 10.41%.In pimento corn tape handling greenhouse, black peach aphid population density is low all the time (after June) after black peach aphid peak period Greenhouse is compareed in pimento, keeps reduced levels.Pimento control greenhouse black peach aphid population quantity at the beginning of 7 months has risen, but pimento is beautiful Peak value compares greenhouse 76.03% far below pimento in rice tape handling greenhouse, as shown in Figure 1.
Circle eggplant corn tape handling greenhouse peak value is late 2 weeks or so in circle eggplant control greenhouse, and peak value also reduces 15.39%;6 The middle ten days and the last ten days moon, circle eggplant compares the 2nd peak of greenhouse black peach aphid popution explosion, and justifies eggplant corn tape handling greenhouse and do not occur again 2 times Break out peak.From by the end of June, black peach aphid density drops to reduced levels in different disposal greenhouse, as shown in Figure 2.
2nd, harmonia axyridia Dynamic state of population in different disposal greenhouse
In corn tape handling greenhouse, the harmonia axyridia due to corn initial inoculation, it is set to be colonized in advance early in greenhouse. With the increase of black peach aphid density, harmonia axyridia quantity is introduced and constantly stable increase.It is heterochromatic as black peach aphid quantity reduces in later stage canopy Ladybug quantity is decreased obviously, and can still possess certain amount harmonia axyridia in corn tape handling greenhouse.Later stage is in order to improve natural enemy Utilization rate, divide harmonia axyridia to be reclaimed corn belt inside greenhouse, therefore data fluctuations occur in investigating.
In pimento corn tape handling greenhouse, harmonia axyridia quantity is consistently higher than in pimento control greenhouse, peakedness ratio pimento pair It is high by 11.63% according to greenhouse.Black peach aphid quantity gradually decreases after mid-June, though harmonia axyridia in pimento corn tape handling greenhouse It has been declined that, average out to 19, maintain the 26.56% of peak value.And harmonia axyridia quantity drastically declines in pimento control greenhouse, Level off to zero, as shown in Figure 3.
In circle eggplant corn tape handling greenhouse, harmonia axyridia quantity is consistently higher than round eggplant control greenhouse, and peak value is higher than circle eggplant pair According to greenhouse 7.08%.After early July, harmonia axyridia quantity slowly declines in circle eggplant corn tape handling greenhouse, is averaged to August part Up to 22, the 11.83% of peak value is maintained.Harmonia axyridia quantity levels off to zero in circle eggplant control greenhouse, as shown in Figure 4.
3rd, the colonization dynamics of the pest control effect of black peach aphid and harmonia axyridia
The pimento greenhouse harmonia axyridia of table 1 colonizes rate, harmonia axyridia and black peach aphid population dynamic investigation result
Table 2 justifies eggplant greenhouse harmonia axyridia and colonizes rate, harmonia axyridia and black peach aphid population dynamic investigation result
Although harmonia axyridia colonizes rate, the amplitude of variation between month is larger, by table 1,2 it can be seen that corn tape handling temperature Room ladybug colonizes rate and is above compareing greenhouse, and black peach aphid population rate of change is less than control greenhouse.
The rate that colonizes that is averaged in pimento corn tape handling greenhouse is higher by 21% than pimento control greenhouse;Because initial stage is used on corn The excessive pipe aphid of cereal, be advantageous to release at initial stage harmonia axyridia, and suppress black peach aphid and break out early stage.Greenhouse, harmonia axyridia are compareed in pimento Reduce with black peach aphid quantity and also gradually decrease, and in pimento corn tape handling greenhouse, harmonia axyridia can still keep 25%~30% Colonize rate.Harmonia axyridia population rate of change is smaller than pimento control greenhouse fluctuation in pimento corn tape handling greenhouse, illustrates heterochromatic Ladybug can preferably colonize.
The rate that colonizes that is averaged in circle eggplant corn tape handling greenhouse is higher than circle eggplant and compares greenhouse 18.5%.Circle eggplant corn tape handling temperature Room harmonia axyridia Dynamic state of population rate is less than circle eggplant and compares greenhouse, it is seen then that maize planting is advantageous to harmonia axyridia and colonized.4-5 Month black peach aphid population rate of change rate of rise be less than circle eggplant compare greenhouse, it is seen that harmonia axyridia has effectively played Pest control efficacy. And 7-9 month harmonia axyridias colonize rate and are significantly higher than round eggplant control greenhouse, illustrate effectively harmonia axyridia can be protected to colonize using corn.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
