Abstract
The invention discloses a preparation method of 1-methylcyclopropene (MCP) slow-release emulsion for crop drought resistance and yield improvement. The preparation method comprises the following steps that: (1) liquid paraffin suspension of 1-lithium methyl cyclopropene is taken, a proper number of oil-soluble nonionic surfactants and a proper amount of silicone oil are added; (2) a certain number of hydrophilic surfactants are added into a certain amount of buffer solution, and the stirring is carried out until the materials are completely dissolved; and (3) the liquid in the first step and the liquid in the second step are respectively filled into two containers of a sprayer, the two kinds of ingredients are mixed according to a fixed proportion under the external force propelling and are spayed onto the surfaces of crops or fruit trees in a fog emulsion mode, or the two kinds of ingredients are respectively sprayed onto the surfaces of the crops or the fruit trees in a certain proportion. The consumption of each material in each step of the method is respectively metered by the weight ratio. The medicament can be simply prepared at low cost and can slowly release 1-MCP to prolong the treatment time on the crops or the fruit trees.
Description
Technical field
The invention belongs to the preparation method of 1-methyl cyclopropene, be specifically related to a kind of preparation method that the crops drought resisting increases income 1-methyl cyclopropene slowly-releasing emulsion that is used for.
Background technology
The extensive underproduction that annual in the world natural calamity and extreme climate all can cause grain; According to FAO's statistics, world food exported country output had descended 4% and 7% respectively because of states such as Australia, Canada, Ukraine meet with extreme climate in 2005,2006.Along with global warming, extreme climate increase, influence will continue to strengthen weather to agricultural, and world agriculture is faced with the multiple baptism of natural calamity.
The grain drop in production that natural calamity and extreme climate cause has the reason of two aspects; The one, natural calamity and extreme climate directly destroy crop; A kind of in addition reason is that crop can discharge a kind of plant hormone-ethene and impels the growth pattern that self gets into self-protection under disadvantageous natural conditions, thereby causes the underproduction.
With the corn is example; After it suffers from the weather of heat and drought condition; It self begins to discharge ethene; When the ethylene receptor site of corn with after these ethene combine, it can transmit some signals and impels leaf to curl to hang keeping moisture content and to reduce photosynthesis, this self-protection pattern of corn can cause the serious underproduction.
Show that after deliberation this reaction of corn is too extreme, in most cases, these abominable natural conditions can't cause so serious underproduction.
For the guiding plant continues normal growth under disadvantageous natural conditions, just need a kind of material to try to be the first and combine, thereby the endogenous ethylene of blocking-up crop is so that it can't transmit the signal of self-protection with the ethylene receptor site of crop.
1-methyl cyclopropene (1-MCP) is a kind of blocking agent of ethene efficiently; It and big 10 times than ethene of the binding ability of ethylene receptor site; And in a single day it combines with receptor site, just will irreversibly block some and impel the gene that plant is ripe and carry out self-protection, below be the structural formula of 1-MCP:
When the crucial growth period of plant meets like extreme climates such as arids as blooming with times such as heading; Thereby using a certain amount of 1-MCP can make plant keep the normal growth situation of a few weeks longer to wait for the arrival of rainwater, irrigation and microthermal climate; Growth along with plant; Itself can grow many new ethylene receptor site again, thereby continues normal growth pattern.
1-MCP has significant inhibitory effect to the underproduction that various abominable natural conditions or damage by disease and insect cause, like arid, high temperature, illumination deficiency, storm, the plague of locusts etc.
For fruit tree, 1-MCP can also effectively prevent when fruit is soon ripe like storm and the overdone fruit that the causes corruption of falling, and makes fruit continued growth under situation about being mature on the whole, and is big to obtain a first watch, the fruit that color and luster is better; The more important thing is the maturity before this fruit of using 1-MCP is keeping adopting to a great extent after harvesting; Thereby prevent to pluck, stack, the extrusion damage in the process such as transportation, prevented also to adopt that fruit further maturation in back causes rots and moisture content, mouthfeel descend.
Because 1-MCP is a gas; And its character is active, is prone to gather explosive, and therefore at present a large amount of what use is the complex compound of itself and alpha-cyclodextrin; It is stable that this complex compound keeps when drying; But beginning to separate complexing under the situation of water having, thereby discharge 1-MCP gas, below is the structural formula of the alpha-cyclodextrin complex compound of 1-MCP:
Though 1-MCP has been successfully applied to enclosure spaces such as freezer, container at present, meeting rapid release loss when in clearing such as field and orchard, using, thereby the effect of not reaching.
Certain company has developed the wetting powder of a kind of 1-MCP of containing, and it is the cyclodextrin-complex of 1-MCP, and wherein the mass percent of 1-MCP is 3.8%, is example to handle 10 mu of ground, and method for using must strict following steps be operated:
1. at first with 4724.92 gram MgSO
4.7H
2O adds in 6.31 premium on currency, and water must be pure and guarantees not copper ions and active carbon, because these materials can quicken the complexing of separating of 1-MCP/ alpha-cyclodextrin, is stirred to dissolving fully;
2. the wetting powder that in the Adlerika that obtains, adds this 1-MCP of containing of 5291.91 grams; Be stirred to the special sprayer of packing into behind the unit for uniform suspension; About 12.62 liters of the cumulative volume of sprayer, and alr mode stipulated requires to stir so that suspension forms whirlpool mixes towards a certain direction; Do not recommend violent unordered stirring, because this can quicken the complexing of separating of 1-MCP/ alpha-cyclodextrin complex compound;
3. if when spraying with agricultural aircraft or helicopter, should be at the height that is positioned at 10 feet of plant top (3.048 meters) with sprinkling;
4. spray in back 1 hour and forbid drenching with rain and spraying irrigation; When wind speed greater than 16 kms/ban use of constantly;
5. for apple and pears, use and to pluck with interior in back three days.
Can find out that from above-mentioned method for using and points for attention this series products has the defective of highly significant,
At first, the effective content of this pulvis is merely 3.8%, and remainder is expensive alpha-cyclodextrin, and these alpha-cyclodextrins can't reclaim after spraying, thereby can predict high cost of this pulvis and price;
Secondly; When the wetting powder that will thisly contain 1-MCP before spraying adds in the aqueous solution supending, can cause the part complex compound to begin decomplexing and merge and discharge 1-MCP gas, and the gas that discharges can be in the overhead generation of container polymerization; There is very big potential safety hazard, when spark is arranged even can blast; For preventing the loss of 1-MCP, used with interior at 5 minutes after requiring prepare suspension, this aggravated the difficulty of operating and cause operating personnel in a hurry;
The 3rd, most critical be after the wetting powder of this 1-MCP of containing sprays, can go out 1-MCP gas by rapid release; And these gases are in the quick loss of clearing meeting; The ratio that combines with the crop ethylene receptor site is low, does not have the effect of anticipation, thereby has caused waste.
Scholar (JUSTIN JACK SCHEINER.EFFECT OF 1-METHYLCYCLOPROPENE ON UPLAND COTTON.Texas A&M University is arranged; 2007) this series products being applied to cotton furthers investigate; But the conclusion that obtains is that cotton is not had production-increasing function; The author thinks because the quick loss of 1-MCP gas has caused the processing time not enough when analyzing reason; The suggestion that he proposes be with 1-MCP be configured to can slowly-releasing medicament, thereby will the processing time extend to 12-24h.
Scholar (Duane Bartholomew and Gail Uruu.Pineapple Control of Flowering Studies.Pineapple news is arranged in addition; Issue No.15; Page 34-37, June, 2008) wetting powder of this 1-MCP of containing is applied to pineapple studies; The conclusion that obtains is that the wetting powder of this 1-MCP of containing does not have substantial effect to pineapple to bloom equally; And thinking that the method for using that provides according to supplier can't use on a large scale, as need in 5 minutes, the medicament for preparing having been sprayed, and all is the comparison exacting terms to the high standard of the water quality of the wetting powder that dissolves this 1-MCP of containing.
In order to overcome the above-mentioned shortcoming that the prior art field contains the 1-MCP product, 1-MCP is studied the people such as Edward professor C.Sisler that make outstanding contribution has developed material (U.S. Pat 2009/0124504) with following structure:
R1 wherein, R2 is an alkyl, aryl or hydrogen atom; Have the compound of said structure and also can combine with ethylene receptor site, thereby play the same effect of 1-MCP, that effect is best in this series compound is R1=R2=C
3H
7, the compound that promptly has following structure:
Name is called N, N-dipropyl (1-cyclopropylene methyl) amine, and this compound can form quaternary ammonium salt soluble in water in acid solution, thereby is fit to crop is sprayed processing.
Compare with 1-MCP/ alpha-cyclodextrin complex compound; Since N, the not loss fast of N-dipropyl (1-cyclopropylene methyl) the amino acid property aqueous solution, and it is than homogeneous; Seem to be fit to very much the processing of field crops and orchard plant; But at first its building-up process is complicated, and need use more expensive lithium methide, and its building-up process is following:
Secondly, the cyclopropene compound is under acid condition and unstable, and along with the reduction bad stability of pH value, so the aqueous solution of this compounds also must join existing usefulness at present, and acid solution is harmful to some crops.
Therefore, this compounds can not large-scale application in crops and fruit tree.
The method that also has is that synthetic 1-MCP gas is absorbed with organic solvent; Process fresh-keeping liquid or spray (seeing patent CN1907046A, CN1927002A) after adding polymerization inhibitor; Organic solvent comprises propane diols, ethanol, isopropyl alcohol, pentaerythrite etc.; Polymerization inhibitor is a p methoxy phenol, 2,4,6-tri-butyl-phenol etc.
Though above invention is claimed 1-MCP and can exist more than 12 weeks by ambient stable that in fact the polymerization speed of 1-MCP in above solution wants much fast, a notable attribute is to occur white cotton-shaped polymer behind the certain hour in the solution; For avoiding polymerization, this solution will be kept under the environment of low temperature, and the words of long-distance transport then need the cooling of ice cube, and this has brought very big difficulty all for the use of this solution and aerosol.
Secondly because absorbent is organic solvent, and cost is higher, can't use on a large scale, and its in the field or the sprinkling in orchard can cause environmental pollution, also exist the danger of blast; The aldehydes matter that organic solvent wherein reaches as polymerization inhibitor all is poisonous, and they exist grave danger to the health of human body, are known carcinogenic substances like phenols.
The existence of organic solvent and phenolic inhibitor also is harmful to crops, vegetables, fruit, flowers once more, may cause the withered and rotten of them.
Therefore the organic solution of this 1-MCP more is not suitable for field crops and fruit tree.
