Description

The using method of the protective agents of a kind of ground maggot

Technical field

The present invention relates to growing vegetables technical field, particularly relate to the using method of the protective agents of a kind of ground maggot.

Background technology

Autumn cabbage, in growth course, avoids ground maggot (also known as root maggot) most, and it stings the epidermis of food Chinese cabbage root, causes the pathogenic bacteria in soil to avail oneself of the opportunity to get in, and causes Chinese cabbage to fall side and rots, not only reduces Chinese cabbage yield, and affect the edibility of Chinese cabbage. As prevented and treated not in time, full field can be made to be injured, cause heavy losses to vegetable grower. The ground maggot of autumn cabbage of causing harm is the larva of Radix Raphani fly, for oligophagy insect, the brassicaceous vegetable such as Chinese cabbage and Radix Raphani of mainly causing harm.

All there is for 1 generation every year in Radix Raphani fly, survive the winter in soil with pupa in various places, rest period about 10 months. The Second Year adult emergence period, mainly in early August, till continuing up to late September, in 8 months, the last ten-days period be occurance peak. Adult every day sooner or later or the cloudy day out movable, noon sunlight strong time lie concealed in Chinese cabbage strain shade place motionless. Autumn Climate warm and moist, occurs serious, and rainfall or after pouring water 1 ~ 2 day, adult quantity significantly increased. After adult is unearthed, through about 7 days, just laying eggs in table soil or table soil seam between the peripheral first and second layer of axil of Chinese cabbage strain and around base portion, ovum is larva, about 30 days larval phases through hatching in 4 ~ 7 days. After this larva occurs, first altering the contiguous petiole base of food Pemisetum flaccidum Griseb. and outer leaf around, then moth food dish root, gallery or the hole in bending, when temperature reduces, harm increases the weight of, and easily brings out the generation of soft rot of cabbage. Conventional chemical pesticide, because spraying for many years, causes that ground maggot develops immunity to drugs, and killing effect is bad, in view of this technical problem, it is necessary to occur that a kind of proportioning is simple, easy to use, it is possible to effectively to kill the using method of the protective agents of a kind of ground maggot of ground maggot.

Summary of the invention

It is an object of the invention to overcome the shortcoming existed in prior art, it is provided that a kind of proportioning is simple, easy to use, it is possible to effectively kill the using method of the protective agents of a kind of ground maggot of ground maggot.

To achieve these goals, the invention provides the using method of the protective agents of a kind of ground maggot, wherein, comprise the steps:

A, on Chinese cabbage furrow plane kind of a nest, each kind of nest spreads 15-20g protective agents as base fertilizer, then broadcasts sowing 2-3 grain seed, is then covered by coating compacting;

B, at the surrounding ditch dug with a plow of Chinese cabbage furrow, ditch depth 30-40cm, spread 1kg protective agents in every meter of ditch as the anti-gully detention of disconnected worm;

The component of described protective agents is Rogor powder, Radix Sophorae Flavescentis powder, 2.5% metrifonate powder, Bravo powder, Bulbus Allii powder, bamboo leaf powder, Fructus Capsici powder.

The protective agents used, including the following component of parts by weight unit:

Rogor powder 2-4 part, Radix Sophorae Flavescentis powder 8-10 part, 2.5% metrifonate powder 1-3 powder, Bravo powder 2-4 part, Bulbus Allii powder 1-3 part, bamboo leaf powder 1-3 part, Fructus Capsici powder 1-2 part.

Or, including the following component of parts by weight unit:

Rogor powder 2-3 part, Radix Sophorae Flavescentis powder 8-9 part, 2.5% metrifonate powder 1-2 powder, Bravo powder 2-3 part, Bulbus Allii powder 1-2 part, bamboo leaf powder 1-2 part, Fructus Capsici powder 1-1.5 part.

2.5% metrifonate powder 1-2 powder unit is mass percent concentration

Advantages of the present invention is that proportioning is simple, easy to use, it is possible to effectively kill ground maggot. During use, when Chinese cabbage length to 2-3 sheet true leaf, carry out field level and dust, to prevent kind of the fly from entering real estate ovum.

Detailed description of the invention:

The using method of the protective agents of ground maggot, wherein, comprises the steps:

A, on Chinese cabbage furrow plane kind of a nest, each kind of nest spreads 15-20g protective agents as base fertilizer, then broadcasts sowing 2-3 grain seed, is then covered by coating compacting;
