CN104365413A - Control method for strawberry gray mold - Google Patents

Abstract

The invention provides a control method for strawberry gray mold. With a high ridge cultivation method adopted for close planting, ventilation is increased; with spraying control used during early flowering, flowering and fruit setting period and before watering, and with a vegetable and fruit pedicle-strengthening medicine sprayed at the same time, cycle fruit setting rate of strawberries is improved, fruit development is promoted, protecting flowers and fruits is focused on, and nutritional balance is coordinated; with the use of plastic film mulching, not only is ground temperature increased and relative air humidity reduced, but also fruit and soil are prevented from direct contact, and thus, the chance of pathogen invasion is reduced, and costs are relatively low.

Description

A kind of prevention and controls of grey mould fruit rot of strawberry

Technical field

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

Background technology

Current greenhouse gardening strawberry 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 Diseases of Strawberry, 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 strawberry, qualitative effects.

Summary of the invention

The technical problem to be solved in the present invention is to provide one can prevent and treat grey mould fruit rot of strawberry in advance, improves the prevention and controls of Yield of Strawberry.

For solving the problems of the technologies described above, the invention provides a kind of physical control method of grey mould fruit rot of strawberry, 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 strawberry;

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

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 strawberry greenhouse, 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: strawberry 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 strawberry 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

The prevention and controls of grey mould fruit rot of strawberry, 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 strawberry;

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

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 strawberry greenhouse, 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 grey mould fruit rot of strawberry, 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 grey mould fruit rot of strawberry, 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 strawberry;

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

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 strawberry greenhouse, 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.
