Abstract
The invention relates to a method for improving the fruit setting rate of tomatoes. Pesticide preparations with p-chlorophenoxyacetic acid, brassinolide and oligosaccharins as active ingredients are mixed, prepared diluent is injected into a small portable sprayer by referring to the dosage of 20-40 mg/kg of the p-chlorophenoxyacetic acid in the composition and diluting the composition according to the same dilution ratio when 2/3 of flowers on inflorescences of the tomatoes are opening, the small portable sprayer is aimed at flowers to be processed which are subjected to uniform atomization and spraying to form tomato flower dripping, and the liquid is prevented from being splashed onto tender leaves to the greatest extent. The method can remarkably improve the fruit setting rate of tomatoes in summer and autumn, make the fruit setting rate basically reach the planting level in spring and improve the economic benefits of planting and meanwhile can reduce the gray mold incidence rate of the tomato fruits and facilitate yield and revenue increasing.
Description
Technical field
The present invention relates to agricultural technology field, be specifically related to a kind of method improving Fructus Lycopersici esculenti fruit-setting rate.
Background technology
Fructus Lycopersici esculenti is happiness temperature but heat labile crop, and under the conditions of Common Cultivation, optimal leaf temperature degree is 20-25 DEG C.Gas
Temperature is low 15 DEG C or then affect pollination of normally blooming higher than 30 DEG C, affects fruit-setting rate.In China, summer and autumn temperature is higher,
If not carrying out artificial pollination or other mode supple-mentary pollination, the natural fruit-setting rate of Fructus Lycopersici esculenti is the lowest, bears fruit to improve Fructus Lycopersici esculenti
Rate, people use the mode of supple-mentary pollination to be i.e. commonly called as the mode of a flower or spraying decoration to improve fruit-setting rate, but simple dependence " Fructus Lycopersici esculenti
Spirit " or 2,4-D processes colored effect or undesirable, and general fruit-setting rate only has the 50% of spring, does not reaches plant development
Expected value, economic benefit is undesirable.
Summary of the invention
The technical problem to be solved is to provide a kind of method improving Fructus Lycopersici esculenti fruit-setting rate, at autumn in summer high temperature season is
Fructus Lycopersici esculenti point flower, can improve the fruit-setting rate of Fructus Lycopersici esculenti.
The present invention solves above-mentioned technical problem and is adopted the technical scheme that: a kind of method improving Fructus Lycopersici esculenti fruit-setting rate, by activity
Composition is that the pesticidal preparations of Brodifacoum, brassin lactones and amino-oligosaccharide mixes, on the inflorescence of Fructus Lycopersici esculenti
When having the flowering of 2/3, in reference group compound, the dosage of Brodifacoum is 20-40 mg/kg, by same equimultiple
Diluted composition, injects portable miniaturised nebuliser by the diluent for preparing, is directed at flower to be processed and carries out uniform atomizing and squirt
For Fructus Lycopersici esculenti point flower, avoid medicinal liquid to splash on tender leaf as far as possible.
The weight ratio of described Brodifacoum, brassin lactones and three kinds of active component of amino-oligosaccharide is 500-800: 1:
100-500, it is preferred that the weight ratio of Brodifacoum, brassin lactones and amino-oligosaccharide is 500: 1: 200.
Described Brodifacoum percentage by weight in the composition is 2.5-8.0%, and brassin lactones is in the composition
Percentage by weight be 0.004-0.01%, amino-oligosaccharide percentage by weight in the composition is 1.0-5.0%.
Described composition pesticide, possibly together with the pigment of 0.1-0.5%, has been put flower for distinguishing and has not been put colored spica, it is to avoid weight
Multiple operation.
The described composition pesticide the most acceptable water preparation of standby one-tenth or solvable powder.
The adjuvant that described composition pesticide adds includes solvent, filler, dispersant, wetting agent, stabilizer or other is useful
The material that and drug effect stable in the formulation in effective ingredient plays.
The present invention has the following advantages and significant technique effect, it is possible to significantly improve the fruit-setting rate of summer and autumn Fructus Lycopersici esculenti, makes to bear fruit
Rate basically reaches plantation in spring level, improves the economic benefit of plantation, can reduce tamato fruit gray mold sickness rate simultaneously, help
In increasing both production and income.

Two, Application Example
Embodiment 1: the compositions that preparation embodiment 1 is prepared as is applied to field medicine effect test
(1) EXPERIMENTAL DESIGN:
Selecting plant tomato strain August in summer, each processes selects the consistent 200 strain tomato plants of growing way, uses hand-held spraying at the florescence
Device is Fructus Lycopersici esculenti point flower according to corresponding medicament and the concentration of each test group, and each batch randomly draws 200 fringes, altogether after point spends 10 days
3 batches, add up each amount of bearing fruit processed, arrange a blank simultaneously.Medicament and the concentration for the treatment of of each test group are as follows:
Test group 1#: the compositions of preparation embodiment 1 correspondence, extension rate is 2000 times, will p-chlorophenoxyacetic acid in compositions
The dosage of sodium is diluted to 25 mg/kg；
Test group 2#: compositions is: 5% Brodifacoum+0.01% brassin lactones water preparation, extension rate is 2000 times
Test group 3#: compositions is: 5% Brodifacoum+2% amino-oligosaccharide water preparation, extension rate is 2000 times
Test group 4#: compositions is: 5% Brodifacoum water preparation, extension rate is 2000 times
(2) investigation method:
First pass through perusal and must be both greater than the fruit-setting rate of blank through the fruit-setting rate of chemicals treatment, in each chemicals treatment
Fruit-setting rate is both greater than under blank premise, calculates test group 1#-3# and bears fruit rate of increase relative to test group 4#.
(3) result of the test:
After point is spent, observing by the naked eye, the fruit-setting rate of blank is the lowest, and the fruit-setting rate of each chemicals treatment group is all than blank
The fruit-setting rate of group is high by more than 100%, and therefore comparative test group 1#-3# is relative to the test group being used alone " Brodifacoum "
The increment rate of bearing fruit of 4#.Statistical analysis, the fruit-setting rate of test group 1# is higher by 42.6% than test group 4#, the fruit-setting rate ratio of test group 2#
Test group 4# is high by 10.4%, and the fruit-setting rate of test group 3# is higher by 5.2% than test group 4#.This shows with Brodifacoum, brassin
Lactone, amino-oligosaccharide three in the range of the compositions of mixture that fruit-setting rate can be made to increase is notable.
(4) determination of yield harvest time:
In harvest time, first pass through perusal blank fructus naturales rate.Because the fructus naturales rate of blank is the lowest, therefore
By test group 1-3# compared with test group 4#, calculate the test group 1#-3# rate of increase of bearing fruit relative to test group 4#.Through statistical
Analysis, test group 1# is than test group 4# volume increase 45.6%, and test group 2# increases production 12.3% than test group 4#, and test group 1# is than test group 2#
Volume increase 8.4%.
Test interval, it is each that to process Fructus Lycopersici esculenti growth normal, without obvious harmful effect, medication district compared with not medication district, Fructus Lycopersici esculenti
Blade, children the tip, the most no abnormal phenomenon of young fruit, show reagent agent in the range of its dosage to Fructus Lycopersici esculenti safety relatively
Good.
In sum, the compositions of the present invention is to use 3 kinds of active component compound schemes, the list of the use with current agricultural production
One preparation " Fructus Lycopersici esculenti spirit " is compared, and has significant effect of increasing production, can reduce the sickness rate of Fructus Lycopersici esculenti gray mold, to crop safety
Good, meet the security requirement of pesticidal preparations.
