Abstract

The invention discloses a key prevention technology for controlling Chinese chive maggots during the production process of Chinese chives. The key prevention technology is characterized in that processes of timely root basking, fertilizer water regulating and Chinese chive maggot catching are performed to prevent pests during pest periods. Accordingly, pesticide dosages are substantially reduced, harm of refractory pests of the Chinese chive maggots in current production of the Chinese chives is eliminated by means of a synthesis technique, simultaneously, edible safety of the Chinese chives is guaranteed, and the prevention technology is simple and practical in method, easy to popularize and suitable for reference using of vast Chinese chive growers.

Description

The key Prevention Technique of control fragrant-flowered garlic maggot harm in the leek production process

Technical field

The present invention relates to the growing vegetables field, specifically the method for preventing and treating of a kind of leek insect.

Background technology

The fragrant-flowered garlic maggot is the intractable insect in the puzzlement leek production process, and to this worm harm, traditional pesticide control is tended to use in current many plantations family that still has, and leek is produced still face relatively more outstanding edible safety problem.Its shortcoming is: be difficult to fundamentally stop the residue of pesticide phenomenon and occur.

Summary of the invention

The present invention prevents and treats the technical problem that exists in the method for solving traditional fragrant-flowered garlic maggot, invents a kind of new technique measure of controlling the harm of fragrant-flowered garlic maggot.Its special character is to comprise following process:

1, shine root: spring is when beginning to thaw in good time, with leek rhizosphere table soil, picks out with the hand rake, makes the leek root soil be exposed to the earth's surface, and fragrant-flowered garlic maggot ovum touches low temperature and dry air and death;

2, rich water regulation and control: after at every turn cutting, when topdressing, the kind of topdressing take through the natural pond slag fertilizer of anaerobic fermentation as first-selected, next is that the fertilizer that fully becomes thoroughly decomposed, treated dregs of beans are fertile, suitably joins and executes the high high-quality compound potassium sulfate fertilizer of potassium content, simultaneously, topdress and to ditch at the leek rhizosphere, by the consumption of every mu of 15-20 kilogram, carbonic hydroammonium is spread fertilizer over the fields the leek root first, impose other fertilizer with water again; If this harvesting does not need to topdress, in time spread fertilizer over the fields ash, reduce leek root soil moisture.

3, Sheng phase control: 1) trap and kill with sugar-vinegar liquid, utilize fragrant-flowered garlic maggot adult to the biological taxis of sugar-vinegar liquid smell with water, sugar, vinegar, dimethoate emulsifiable concentrate in 5: 3: 1: 0.15 ratio is combined together, notice that timing adds sugar first water and melts, add again other batchings, contain in the container, when needing to strengthen control efficiency, can add high number of degrees liquor with reference to 10 times of ratios of vinegar consumption, effect is pretty good.2) be diluted to 100 times of liquid with BT bacteria agent 250 times of liquid sprayings control adult or 1.1% matrine pulvis 2-4kg, fill with root at leek root trench digging and kill larva, it is 10 days that above-mentioned biopesticide uses safety interval.

Technique effect

Technique effect of the present invention is, adopts technique scheme, can significantly alleviate the harm of fragrant-flowered garlic maggot, and preventive effect reaches more than 96%, and method is easy, practical, draws materials easily.Particularly importantly, conscientiously reduce the pesticide dosage on the leek in the past, stopped the leek Pesticide Residue and occur, guaranteed the leek edible safety.

Specifically preventing and treating main points is:

1, shine root: the adult of fragrant-flowered garlic maggot claims the environment of Bradysia odoriphaga happiness high temperature low humidity, and is the most vigorous in activity in the spring of drying in good time.At the beginning of late April to 5 month, general daytime is movable, and hide night.Spring is when beginning to thaw, and with the soil of the table around the Radix Folium Allii tuberosi, picks out with the hand rake, makes the fragrant-flowered garlic maggot make the fragrant-flowered garlic maggot be exposed to the earth's surface, touches low temperature and dry air, in-4 ℃ low temperature and humidity are 60% environment, and can be dead through 2～3 hours fragrant-flowered garlic maggots.

2, crops for rotation management: one batch of every harvesting, water in conjunction with topdressing, in time spread fertilizer over the fields ash, when spreading ash, an animal-drawn seed plough to open leek rhizosphere table soil, spread root, in high temperature and rainy season autumn in summer, soil acidity strengthens, and can add in the ash by every mu of 15-20 kilogram quicklime when spreading ash and spread fertilizer over the fields.In addition, topdress and answer the fertilizer that first-selected natural pond slag is fertile or fully become thoroughly decomposed, treated dregs of beans is fertile, secondly is the high high-quality compound potassium sulfate fertilizer of potassium content, and foliage-spray preferably uses natural pond liquid, and Pesticidal and sterilizing is effective.By these measures, the soil acidity or alkalinity during can effectively regulating leek and growing reaches more than 97% the preventive effect of fragrant-flowered garlic maggot, effectively stops the harm of fragrant-flowered garlic maggot.

3, Sheng phase control: annual spring and autumn fragrant-flowered garlic maggot adult and larva cause harm the Sheng phase, take following way control: 1) trap and kill with sugar-vinegar liquid, utilize the fragrant-flowered garlic maggot to the biological taxis of sugar-vinegar liquid smell with water, sugar, vinegar, dimethoate emulsifiable concentrate in 5: 3: 1: 0.15 ratio is combined together, notice that timing adds sugar first water and melts, add again other batchings, contain in the container, when needing to strengthen control efficiency, can add high number of degrees liquor with reference to 10 times of ratios of vinegar consumption, effect is pretty good.2) be diluted to 100 times of liquid with BT bacteria agent 250 times of liquid sprayings control adult or 1.1% matrine pulvis 2-4kg, fill with root at leek root trench digging and kill larva, it is 10 days that above-mentioned biopesticide uses safety interval.

Claims

Control the key Prevention Technique that the fragrant-flowered garlic maggot endangers in the leek production process, it is characterized in that comprising following process:

1. shine root: spring is when beginning to thaw in good time, with leek rhizosphere table soil, picks out with the hand rake, makes the leek root soil be exposed to the earth's surface, and fragrant-flowered garlic maggot ovum touches low temperature and dry air and death.
2. rich water regulation and control: after at every turn cutting, when topdressing, the kind of topdressing take through the natural pond slag fertilizer of anaerobic fermentation as first-selected, next is that the fertilizer that fully becomes thoroughly decomposed, treated dregs of beans are fertile, suitably joins and executes the high high-quality compound potassium sulfate fertilizer of potassium content, simultaneously, topdress and to ditch at the leek rhizosphere, by the consumption of every mu of 15-20 kilogram, carbonic hydroammonium is spread fertilizer over the fields the leek root first, impose other fertilizer with water again; If this harvesting does not need to topdress, in time spread fertilizer over the fields ash, reduce leek root soil moisture.
3. adult Sheng phase control: 1) trap and kill with sugar-vinegar liquid, utilize the fragrant-flowered garlic maggot to the biological taxis of sugar-vinegar liquid smell with water, sugar, vinegar, dimethoate emulsifiable concentrate in 5: 3: 1: 0.15 ratio is combined together, notice that timing adds sugar first water and melts, add again other batchings, contain in the container, when needing to strengthen control efficiency, can add high number of degrees liquor with reference to 10 times of ratios of vinegar consumption, effect is pretty good.2) be diluted to 100 times of liquid with BT bacteria agent 250 times of liquid sprayings control adult or 1.1% matrine pulvis 2-4kg, fill with root at leek root trench digging and kill larva, it is 10 days that above-mentioned biopesticide uses safety interval.
