CN104335877A - Prevention and control method of grape gray mould - Google Patents

Abstract

The invention relates to and provides a prevention and control method of grape gray mould. The method adopts a high-ridged cultivation method to reasonably perform close planting, can improve the ventilation, sprays pesticide for prevention and control at the earlier stage of flowering period, during blossom and fruit bearing period and before watering, improves the grape circulating fruit setting rate by spraying plant base strengthening agent, promotes fruit development, focuses on protecting flower and fruit, coordinates nutrient balance, increases the earth temperature and reduces the relative air humidity by adopting a mulching film for covering, meanwhile can prevent fruit from directly contacting with soil, thereby reducing the opportunity of pathogenic bacteria invasion, and is relatively low in the cost.

Description

A kind of prevention and controls of grape grey mould

Technical field

The present invention relates to a kind of prevention and controls of grape head blight.

Background technology

Current greenhouse gardening grape is all generally that flat furrow are horizontal, due to the high temperature and humidity microclimate that facility cultivation is formed, advantage is provided for grape disease, wherein gray mold often causes flower and a large amount of of fruit to rot, susceptible variety diseased fruit rate can reach 30% ~ 60%, very large to the output of grape, qualitative effects.

Summary of the invention

The technical problem to be solved in the present invention is to provide one can prevent and treat grape grey mould in advance, improves the prevention and controls of vintage.

For solving the problems of the technologies described above, the invention provides a kind of physical control method of grape grey mould, while guarantee prevents and treats gray mold, the use of agricultural chemicals can also be reduced:

Step one: get the strong base of a fruit spirit of appropriate dish fruit, to be often aly uniformly mixed with 15 kg of water, to bloom early stage, the bloom phase of bearing fruit and sprinkling before watering at grape;

Step 2: adopt and dig the high ridge that the soil in booth is excavated into row spacing 55 cm, ditch depth 35 cm, furrow width 25 cm by ridge machine or artificial mode, during cultivation, every ridge plants 2 row, spacing in the rows 15 ~ 18 cm;

Step 3: block mulch film with ultraviolet and the plot under booth is all covered;

Step 4: laying temperature meter and moisture meter in each grape booth, when the condition of temperature 18 ~ 24 DEG C, humidity 92% ~ 95%, will open booth ventilated in time, ensures that temperature and humidity is not in above-mentioned scope.

The invention has the beneficial effects as follows: grape bloom early stage, bloom the phase of bearing fruit and spray before watering medicine control; coordinate and spray dish fruit strong base of a fruit spirit raising grape circulation fruit-setting rate; promote fruit development, emphasis flower and fruit protecting, coordinate nutrient balance; high ridge rational close planting can increase the air permeability of booth inside; with plastic mulching, can not only ground temperature be improved, reduce relative air humidity; fruit can also be avoided directly to contact with soil simultaneously, thus reduce the chance of pathogen intrusion.

Embodiment

A prevention and controls for grape grey mould, first will note following requirement: 1, the service time of the strong base of a fruit spirit of dish fruit should phase, the phase of bearing fruit and before watering of blooming before flowering before control.2, preparation tool comprises the strong base of a fruit spirit of dish fruit, digs ridge machine, mulch film, thermometer, moisture meter.

Prevent and treat step as follows:

Step one: get the strong base of a fruit spirit of appropriate dish fruit, to be often aly uniformly mixed with 15 kg of water, to bloom early stage, the bloom phase of bearing fruit and sprinkling before watering at grape;

Step 2: adopt and dig the high ridge that the soil in booth is excavated into row spacing 55 cm, ditch depth 35 cm, furrow width 25 cm by ridge machine or artificial mode, during cultivation, every ridge plants 2 row, spacing in the rows 15 ~ 18 cm;

Step 3: block mulch film with ultraviolet and the plot under booth is all covered;

Step 4: laying temperature meter and moisture meter in each grape booth, when the condition of temperature 18 ~ 24 DEG C, humidity 92% ~ 95%, will open booth ventilated in time, ensures that temperature follows humidity not in above-mentioned scope.

Adopt said method, not only can reduce the incidence of disease of grape grey mould, the usage amount of agricultural chemicals can also be reduced, reduce to pollute, and cost is lower.

Claims (1)

1. a prevention and controls for grape grey mould, is characterized in that: described prevention and controls comprises the steps:

Step one: get the strong base of a fruit spirit of appropriate dish fruit, to be often aly uniformly mixed with 15 kg of water, to bloom early stage, the bloom phase of bearing fruit and sprinkling before watering at grape;

Step 2: adopt and dig the high ridge that the soil in booth is excavated into row spacing 55 cm, ditch depth 35 cm, furrow width 25 cm by ridge machine or artificial mode, during cultivation, every ridge plants 2 row, spacing in the rows 15 ~ 18 cm;

Step 3: block mulch film with ultraviolet and the plot under booth is all covered;

Step 4: laying temperature meter and moisture meter in each grape booth, when the condition of temperature 18 ~ 24 DEG C, humidity 92% ~ 95%, opens booth ventilated in time, ensures that temperature and humidity is not in above-mentioned scope.
