Abstract

The invention provides a method for assisting control of underground insect pests in a seedling stage of cucumbers by utilizing sudangrass. The sudangrass is planted in the field before field planting of the cucumbers is carried out, seeds of the sudangrass are coated with insecticide, the insecticide is sprayed on seedlings of the cucumbers and sudangrass, underground insects in the cucumber field are shunted, trapped and killed, and the effect is better than that of single use of a pesticide used for treating the cucumbers.

Description

A kind of method utilizing Sudan grass to assist cucumber control underground pests in seedling stage

Technical field

Utilizing Sudan grass to assist a method for cucumber control underground pests in seedling stage, belong to cucumber controlling underground pest technical field, is more particularly a kind of method utilizing Sudan grass to assist cucumber control underground pests in seedling stage.

Background technology

The control of cucumber at seedling stage soil insect is a great problem of cucumber production always, the soil insect of cucumber at seedling stage has mole cricket, black cutworm, wireworm and grub, these insects are in the seedling stage of cucumber or from the ground, or the cucumber seedling that to bite from underground, cause the dead strain of cucumber to be short of seedling, cause cucumber field to be short of seedling disconnected ridge.Cucumber is a kind of crops of thin planting, and every mu of density only has 2-3 thousand strain usually, is easy to cause the remarkable underproduction to cucumber yield if field is short of seedling, so the control of cucumber at seedling stage soil insect is the important topic of cucumber production.Although pesticide chemical enterprise has produced many new agricultural chemicals in order to prevent and treat the soil insect of cucumber in recent years, effect still can not be fully up to expectations, and particularly in the time of the large generation of soil insect, only on cucumber, applying pesticides effect is unsatisfactory.Develop the prophylactico-therapeutic measures of new cucumber at seedling stage soil insect, improve the control efficiency of cucumber at seedling stage soil insect further, remain a problem demanding prompt solution.

Summary of the invention

The object of the present invention is to provide a kind of cucumber field planting Sudan grass, applying pesticides, prevents the technical measures of cucumber soil insect more effectively simultaneously.

The present invention is achieved in that

Utilize Sudan grass to assist a method for cucumber control underground pests in seedling stage, it comprises the following steps:

(1) before cucumber field planting field sowing Sudan grass, field planting cucumber after Sudan grass emerges, the distance of Sudan grass and cucumber plant is 10-15cm;

(2) insecticide Cotton seeds is carried out before Sudan grass sowing;

(3) field planting sprays insecticide after surviving on cucumber and Sudan grass plant;

(4) when cucumber grows to 25cm height, go out except Sudan grass with unifacial leaf weed killer herbicide.

Beneficial effect of the present invention

Effect of the present invention is, Sudan grass is sowed before cucumber field planting, the seed of Sudan grass and seedling just can shunt the harm of soil insect to cucumber seedling, and the seed of Sudan grass is the same with cucumber with seedling, all use of insecticide carries out spray process, has become the poison bait of soil insect, and insect just can be killed lethal once feed, the harm of soil insect to cucumber seedling can be reduced further, improve the control efficiency of cucumber field soil insect.On the plant of Sudan grass and cucumber, spray insecticide seedling stage is be unearthed at night to kill, and shifts harm on the ground, gnaws the black cutworm of seedling.Sudan grass, in seedling symbiosis a period of time of the field of cucumber and cucumber, after treating that cucumber seedling grows to 25cm height, when being not easy endangered by soil insect, then carrying out chemistry with unifacial leaf weed killer herbicide to Sudan grass and goes out and remove, make it the growth not affecting the cucumber middle and later periods.The present invention prevents the principle of cucumber at seedling stage soil insect to be to shunt insect, divides and rule.Seed and the seedling of Sudan grass is increased in the field of cucumber; that has disperseed soil insect takes food target; the agricultural chemicals utilizing seed dressing and seedling stage to spray while dispersion is trapped and killed insect; define the multiple protective to field cucumber seedling, thus effect is better than being used alone chemical pesticide and dresses seed to cucumber or the technique effect of foliage-spray control soil insect.

Embodiment

Utilize Sudan grass to assist a method for cucumber control underground pests in seedling stage, it comprises the following steps:

(1) before cucumber field planting field sowing Sudan grass, field planting cucumber after Sudan grass emerges, the distance of Sudan grass and cucumber plant is 15cm;

(2) with Imidacloprid desinsection seed coating medicine, Cotton seeds is carried out to seed before Sudan grass sowing;

(3) field planting sprays decis insecticide after surviving on cucumber and Sudan grass plant;

(4) when cucumber grows to 25cm height, go out except Sudan grass with unifacial leaf weed killer herbicide haloxyfop-r-methyl.

Imidacloprid desinsection seed coating medicine can kill soil insect mole cricket, grub, wireworm are held concurrently and the ground insect aphid in seedling stage and thrips, and to spray decis in seedling stage be to eliminate the black cutworm shifting harm on the ground.

Claims (1)

1. utilize Sudan grass to assist a method for cucumber control underground pests in seedling stage, it is characterized in that, it comprises the following steps:

(1) before cucumber field planting field sowing Sudan grass, field planting cucumber after Sudan grass emerges, the distance of Sudan grass and cucumber plant is 10-15cm;

(2) insecticide Cotton seeds is carried out before Sudan grass sowing;

(3) field planting sprays insecticide after surviving on cucumber and Sudan grass plant;

(4) when cucumber grows to 25cm height, go out except Sudan grass with unifacial leaf weed killer herbicide.
