Abstract

The invention belongs to the technical field of strawberry cultivation, and particularly relates to a method for preventing a pesticide from being sprayed to strawberry fruits. According to the method, through the steps of setting up a fruit covering shed, separating fruits and leaves, picking the fruits and the like, an operating method for preventing the pesticide from being sprayed to the strawberry fruits is established; and the method is simple, low in cost, stable, efficient, and convenient to use.

Description

A kind of method that prevents agricultural chemicals spray and strawberry fruit

Technical field

The invention belongs to the cultivated strawberry technical field, be specifically related to a kind of method that prevents agricultural chemicals spray and strawberry fruit.

Background technology

Strawberry is main fruit both domestic and external, and the cultivation potentiality are large, and market efficiency is good, if but do not carry out the extermination of disease and insect pest, can cause quality to descend the serious consequence that benefit is low.

Bagging is the current basic skills that prevents agricultural chemicals spray and fruit, be used widely in apple, pears, grape, peach etc. fruit tree at present, but strawberry cause and effect shape is little, and quantity is many, and is large etc. former thereby can't promote with the fructescence difference of different levels of inflorescence time.Simultaneously, in a single day therefore coarse the and peeling difficulty of strawberry fruit is infected with agricultural chemicals, also be difficult to be eliminated totally with conventional methods such as washing by rubbing with the hands, brew.The people such as Tang Shujun studies show that to Baoan district of Shenzhen city 2004-2009 fruit persticide residue the residue of pesticide exceeding standard rate of strawberry is the highest, reaches 41.7%.Therefore, the new method of initiative isolation strawberry fruit and Pesticide Exposure is very necessary.

Summary of the invention

The problem that the present invention need to solve is for preventing that agricultural chemicals spray and strawberry fruit from providing a kind of simple to operate, with low cost, stability and high efficiency, method easy to use.

Purpose of the present invention can realize by following method:

(1) build cover fruit canopy:

Cover fruit frame setting: before the strawberry field planting, finish and build furrow and the plastic mulching of furrow face, when treating that strawberry blooms, every several plant cover fruit frame is set in the ranks, cover fruit frame requires firmly, the frame height is 2/3rds of height of seedling, frame is wide take 5 centimetres of distance both sides plant as degree, and limit row place frame reductions half is high in the middle of the shape need, both sides are low, hydrops not when guaranteeing that medicament sprays;

Cover fruit canopy is cut apart: flee in cover fruit canopy for preventing the disease worm, requirement is taken the bar mulch film at each shelf and is separated cover fruit canopy, and the mulch film length requirement rides over behind the cover fruit frame at least one and can land, complete cover fruit frame cross section after width requirement is put up, fixed after hanging up properly, prevented landing;

Cover fruit frame covers: the covering of cover fruit frame is overlay, the length of plastic foil is slightly to be longer than in the ranks as degree, width forms apart from ground 3 centimetres high canopy side seam as degree to cover rear both sides, can make things convenient for like this immigration of strawberry flowers and fruits and shift out, guarantee ventilation and the insect discrepancy of canopy chamber, plastic foil requires to carry out two ends and fixes after covering, middle press mold is with falling prevention frame;

(2) leaf really splits processing:

Cover fruit canopy build complete after, with on the plant the inflorescence of living flowers and fruits place under the canopy from the canopy side seam, and leaf is climing vertically outside canopy, and with U-shaped iron wire by its two ends are inserted in soil, U-shaped inner bottom part is pushed down and is prevented that inflorescence from provoking in the middle part of the inflorescence, escapes to canopy;

(3) picking fruit:

During picking fruit, pull up U-shaped iron wire, lift up slightly the canopy side seam, take out fruit ear, win fruit, put back to afterwards fruit ear, managed covering, continue to use.

The present invention compared with prior art its beneficial effect is: prevented that strawberry flowers and fruits growing period from directly contacting with the agricultural chemicals of sprinkling, controlled the residue of pesticide of fruit surface; Early fruit maturity 1-2 days; With low cost, management expectancy is low, is suitable for nuisanceless strawberry production, and green strawberry production and organic strawberry production are convenient to promote.

The invention solves the technical barrier of the strawberry fruit medicament pollution that causes because spraying insecticide.

Embodiment

(1) cover fruit canopy is built:

The setting of cover fruit frame: before the strawberry field planting, finish and build furrow and the plastic mulching of furrow face, when to be bloomed, inserting arch cover fruit frame every 1 plant in the ranks, cover fruit frame requires firmly, and the frame height is 15 centimetres, frame wide take 5 centimetres of distance both sides plant for degree, the frame reductions of limit row place is partly;

Cover fruit canopy is cut apart: really flee in the canopy at cover for preventing the disease worm, requirement is taken the bar mulch film at each shelf and is separated cover fruit canopy, long 20 centimetres of mulch film, and the complete cover fruit of energy frame cross section was fixed after hanging up properly after width requirement was put up, and prevented landing;

Cover fruit frame covers: the covering of cover fruit frame is transparent polyethylene plastic film, the length of plastic foil is slightly to be longer than in the ranks as degree, width forms apart from ground 3 centimetres high canopy side seam as degree to cover rear both sides, can make things convenient for like this immigration of strawberry flowers and fruits and shift out, guarantee ventilation and the insect discrepancy of canopy chamber, plastic foil requires to carry out two ends and fixes after covering, 10 seedlings in middle every interval, one arch cover fruit frame that pressurizes is in case the landing of canopy film;

(2) leaf really splits processing:

Cover fruit canopy build complete after, with on the plant the inflorescence of living flowers and fruits place under the canopy from the canopy side seam, and leaf is climing vertically outside canopy, inserts in the soil by the U-shaped iron wire with long 10 centimetres of two ends, pushes down the inflorescence middle part by U-shaped inner bottom part and prevents that inflorescence from provoking, and escapes to canopy;

(3) picking fruit:

During picking fruit, can pull up U-shaped iron wire, lift up slightly the canopy side seam, take out fruit ear, win fruit, put back to afterwards fruit ear, manage covering, continue to use.

Claims (1)

1. one kind prevents that agricultural chemicals from spraying and the method for strawberry fruit, and its feature is made of following steps:
