Abstract

The invention belongs to application of diquat dibromide in pepper ripening. A pepper ripening agent used in the invention mainly depends on touch killing and is free of uptake and translocation, and has the advantage of being good in safety, low in usage quantity, free of toxins and residues and the like. After 2-3 days of using, leaves can be made dry and fall off, generation of pepper endogenous ethylene is promoted, then fruit ripening is promoted, and the purposes of unified harvesting and mechanical harvesting can be achieved.

Description

Diquat capsicum urge red in application

Technical field

The invention belongs to crops ripening technique field, be specifically related to a kind of diquat capsicum urge red in application.

Background technology

In the fifties, just known magnesium chlorate, Thidiazuron, as defoliant, are mainly used in cotton.But in capsicum defoliant, the requirement of people to modern defoliant improves constantly, except considering economy and environment factor, every to effect, effective ingredient consumption, residual, toxicity and manufacture, factor that storage satety is relevant all will relate to.

When magnesium chlorate acts on cotton leaf, the water content of cotton leaf can be made significantly to reduce, and photosynthesis weakens, and enzymic activity is suppressed, and makes leaf base form absciss layer rapidly, thus plays the effect of disleave.Thidiazuron is a plant growth regulators, has Uptake and translocation, after it is absorbed by plants, can impels the chorista self-assembling formation between petiole and stem and fall leaves.Both usage variances on cotton are comparatively large, and it is 100-150g/ mu that magnesium chlorate is used for effective ingredient consumption in cotton defoliation, and it is 10-20g/ mu that Thidiazuron is used for effective ingredient consumption in cotton defoliation.

Magnesium chlorate is a kind of chemical substance, tool excitant.Headache, dizzy, weak is there is after contact; It is even dead that high concentration can cause disordered breathing, collapse.Eye and skin contact irritant, can cause and burn.Mix can form explosive mixture with reductant, organic matter, combustibles such as sulphur, phosphorus or metal dust etc.Thidiazuron is a plant growth regulators, has Uptake and translocation, is not generally proposed to be used in edible plant picking time.

Summary of the invention

The object of this invention is to provide that a kind of safety is high, consumption is low, the diquat of nontoxic residue-free capsicum urge red in application.

For achieving the above object, one of the technical solution used in the present invention is, diquat capsicum urge red in application.Preferred: diquat consumption is 4-10g/ mu.

Diquat is when capsicum urges red middle application, and to be watered after dilution 7-10 days before gathering, foliage-spray uses.

The present invention adopt another technical scheme be diquat and ethrel mixture capsicum urge red in application, diquat consumption is 4-8g/ mu, ethrel consumption is 1-5g/ mu.Preferred: diquat consumption is 4-6g/ mu, ethrel consumption is 1-5g/ mu.

The mixture of diquat and ethrel is when capsicum urges red middle application, and to be watered after dilution 7-10 days before gathering, foliage-spray uses.

The beneficial effect that the present invention produces is: the present invention capsicum urge red in diquat used, to tag, without Uptake and translocation, there is the advantages such as safety is good, consumption is low, nontoxic residue-free.2-3 days after a procedure, can make blade drying come off, and promotes the generation of capsicum endogenous ethylene, and then promotes that fruit is urged red, can reach unified and gather and the object of mechanical harvesting.

Embodiment

For checking the actual effect of medicament provided by the present invention on capsicum further, inventor has been contrast experiment in the 8-9 month in 2014 in Henan Zhongmou County capsicum (capsicum annum fasciculatum).

test method

Gather first 10 days in capsicum, by diquat single dose or use diquat and each concentration for the treatment of of ethrel mixture to carry out spraying to Pepper Leaves to process.Spraying water consumption is 30kg/ mu.

investigation method

2.1 poisoning investigation

Investigate before gathering with or without poisoning (shedding).

The poisoning degree of every community is distinguished with poisoning grade scale, with-,+, ++, +++ represent.

-: without shedding;

+: hand slight shedding, does not affect and gathers, and can not cause crop failure;

++: hand fruit branch shedding is serious, causes loss to a certain degree to the output of crop;

+++: shedding is serious, causes heavy losses to the output of crop.

2.2 efficacy survey

2.2.1 defoliation effect investigation

Every community random labelling 10 strain capsicum, investigates the complete stool number of blade of plant of listing before medicine, after dispenser, 3d, 7d investigate the plant complete stool number of blade of listing, and calculates disleave rate.

2.2.2 Redening investigation

Every community random labelling 10 strain capsicum, after dispenser, 7d investigates coloring case, accounts for the percentage of whole fruit area to delimit grade scale with the upper stained area of each fruit.

Grade scale is as follows:

1 grade: stained area accounts for less than 20% of whole fruit ear area;

2 grades: stained area accounts for the 21%-40% of whole fruit ear area;

3 grades: stained area accounts for the 41%-60% of whole fruit ear area;

4 grades: stained area accounts for the 61%-80% of whole fruit ear area;

5 grades: stained area accounts for the 81%-100% of whole fruit ear area.

results and analysis

Diquat or diquat and ethrel mixture urge red impact to the results are shown in following table 1 on capsicum disleave:

Table 1 diquat or diquat and ethrel mixture are urged capsicum disleave red affects result

。

Table 1 result of the test shows, capsicum uses diquat or diquat and ethrel mixture significantly can promote Pepper Leaves drying, come off, and then promotes that fruit is urged red, be beneficial to unified gathering.
