Abstract
The invention provides a method for preventing and treating seedling-period underground insect damages corns with help of sudan grass. The sudan grass is planted in a corn field when corns are sowed; seeds and seedlings of the corns and the sudan grass are treated by insecticide drugs so that underground insects of the corn field are separated and trapped; and the effect is better than that of a manner of treating the corns by independently utilizing pesticides.
Description
Technical field
A kind of method utilizing arabian cron to assist Semen Maydis preventing and treating underground pests in seedling stage, belongs to technical field of pest control under milpa, more specifically a kind of method utilizing arabian cron to assist Semen Maydis preventing and treating underground pests in seedling stage.
Background technology
The preventing and treating of Maize at Seedling Stage subterranean pest-insect is always up a great problem of Maize Production, the subterranean pest-insect of Maize at Seedling Stage mainly has black cutworm, wireworm, Gryllotalpa and Holotrichia diomphalia Bates, these three insect is in the seedling stage of Semen Maydis or from the ground, or the maize seedling that bites from underground, cause the dead strain of Semen Maydis to be short of seedling, cause corn field to be short of seedling disconnected ridge.Semen Maydis is the crops of a kind of field thin planting, and every mu of density generally only has 3000-5000 thousand strain, if field is short of seedling is easy to corn yield is caused the notable underproduction, so, the preventing and treating of Maize at Seedling Stage subterranean pest-insect is the important topic of Maize Production.Although pesticide chemical enterprise has produced many new pesticide in order to prevent and treat the subterranean pest-insect of Semen Maydis in recent years, but effect still can not be fully up to expectations, particularly in the time of the big generation of corn field subterranean pest-insect, unsatisfactory only in applying pesticides effect on Semen Maydis.Develop the prophylactico-therapeutic measures of new Maize at Seedling Stage subterranean pest-insect, improve the prevention effect of Maize at Seedling Stage subterranean pest-insect further, remain a problem demanding prompt solution.
Summary of the invention
It is an object of the invention to provide a kind of chemical prevention to be combined with biological control measure, be more effectively prevented from the technical measures of Semen Maydis subterranean pest-insect.
The present invention is achieved in that
A kind of method utilizing arabian cron to assist Semen Maydis preventing and treating underground pests in seedling stage, it comprises the following steps:
(1) in the ranks sowing arabian cron when corn seeding in Semen Maydis, the spacing of arabian cron and Semen Maydis plant is 10-15cm simultaneously；
(2) insecticide Dressing is all carried out before arabian cron and corn seed sowing；
(3) after emerging on field corn and arabian cron foliage-spray insecticide；
(4) when Semen Maydis grows to 8 true leaves, use Semen Maydis herbicides special, in conjunction with chemical weed control, wheat seedling is removed in the lump.
Beneficial effects of the present invention
The effect of the present invention is in that, in corn field, arabian cron is sowed while corn seeding, the seed of arabian cron and seedling just can tap the subterranean pest-insect harm to maize seedling, and the seed of arabian cron is the same with Semen Maydis with seedling, all using insecticide to process, become the poison bait of subterranean pest-insect, insect just can be killed lethal once feed, the subterranean pest-insect harm to maize seedling can be reduced further, improve the prevention effect of corn field subterranean pest-insect.Seedling stage, the foliage-spray insecticide at arabian cron and Semen Maydis was to be unearthed at night to kill further, shifts harm on the ground, gnaws phytophagous black cutworm.Arabian cron is in the seedling symbiosis a period of time in the field of Semen Maydis Yu Semen Maydis, after treating that maize seedling grew to for 8 leaf phases, it is not easy to when endangered by subterranean pest-insect, then with Semen Maydis herbicides special, arabian cron carries out chemistry and goes out and remove, so as to do not affect the growth of Semen Maydis middle and late stage.The present invention prevents the principle of Maize at Seedling Stage subterranean pest-insect to be in that shunting insect, divides and rule.Seed and the seedling of arabian cron is increased in the field of Semen Maydis; that has disperseed subterranean pest-insect takes food target; utilize the pesticide of seed dressing and seedling spraying that insect is trapped and killed scattered simultaneously; define the multiple protective to field corn Seedling, thus effect is better than being used alone chemical pesticide and Semen Maydis is dressed seed or the technique effect of foliage-spray preventing and treating subterranean pest-insect.
Detailed description of the invention
A kind of method utilizing arabian cron to assist Semen Maydis preventing and treating underground pests in seedling stage, it comprises the following steps:
(1) in the ranks sowing arabian cron when corn seeding in Semen Maydis, the spacing of arabian cron and Semen Maydis plant is 15cm simultaneously；
(2) " chlopyrifos " insecticide Dressing is all used before arabian cron and corn seed sowing；
(3) Semen Maydis and arabian cron emerge after on field corn and arabian cron foliage-spray chrysanthemum ester insecticide " decis "；
(4) when Semen Maydis grows to 8 true leaves, with Semen Maydis herbicides special " bud is defended ", in conjunction with chemical weed control, wheat seedling is removed in the lump.
Claims (1)
1. one kind utilizes the method that arabian cron assists Semen Maydis preventing and treating underground pests in seedling stage, it is characterised in that it comprises the following steps:
(1) in the ranks sowing arabian cron when corn seeding in Semen Maydis, the spacing of arabian cron and Semen Maydis plant is 10-15cm simultaneously；
(2) insecticide Dressing is all carried out before arabian cron and corn seed sowing；
(3) after emerging on field corn and arabian cron foliage-spray insecticide；
(4) when Semen Maydis grows to 8 true leaves, use Semen Maydis herbicides special, in conjunction with chemical weed control, wheat seedling is removed in the lump.
