Description
Technical field
The present invention relates to a kind of watermelon anti-cracking agent and its applications.
Background technique
Watermelon is summer important one of fruit, and sweetness is tasty and refreshing, can relieve summer heat and quench one's thirst, and has diuresis, defaecation, toxin expelling, rushes down
Fire and other effects nowadays has become four seasons cultivation, the annual fresh food fruit enjoyed.However, in the course of cultivation, due to temperature
Discomfort, with fertile improper, water stress, the reasons such as mismanagement and hormone, kind, what usually appearance was different degrees of splits melon phenomenon,
Especially watermelon early spring greenhouse cultivation is easier to cause to split melon, the light underproduction 5~10%, the serious underproduction 50~60%, even
Total crop failure, brings very huge economic loss to melon grower.
Splitting melon is exactly in watermelon growing growth course or before harvesting, from melon umbilical region natural cracking at two valves or more valves.It splits
Melon rate is generally more than 16%, some special kinds, splitting melon rate can achieve 30% or more, seriously affected watermelon quality and
The loss of yield, melon grower is very big.The main reason for watermelon dehiscent fruit generates has: 1, kind reason: it is different that different cultivars splits melon degree
Sample, the thin and crisp kind of pericarp, small fruit type kind melon easy to crack.2, rich water factor: early period, rich water was insufficient, and later period rich water abundance is easy to crack
Melon；The plot melon easy to crack of calcium deficiency, magnesium deficiency；The Fruit later period meets low temperature heavy rain or overirrigation, will also result in and splits melon.3, watermelon
When into picking time and most thin melon skin, it is easy to cause to split melon in this period for many variety of watermelon.Such as Huang
Small beautiful, red small jade, 84-24 etc., it is only 0.5 centimetre or so of skin depth, the vibration such as slightly split by force, continuously negative when fruit is by maturation
Rain and the unexpected broad irrigation of continuous drought will cause and largely split melon.
In the prior art, to prevent watermelon from splitting melon, melon grower mostly uses the strong muskmelon pedicel spirit of sprinkling, by keeping watermelon idiotrophic
Equilibrium, carry out the generation of anti-crack arrest melon, but effect is unobvious, preventive effect is little, is not able to satisfy the normal production of watermelon.
Summary of the invention
For the above-mentioned prior art, the present invention provides preparation --- the watermelon anti-cracking agents that can effectively prevent watermelon and split melon.
Watermelon anti-cracking agent of the invention, the effect of greatly improving watermelon anti-fruit-cracking, the demonstration test for being close on thousand mu by 3 obtain
Satisfactory control efficiency.
The present invention is achieved by the following technical solutions:
A kind of watermelon anti-cracking agent, is made from the following raw materials in parts by weight: 5~20 parts of chitosan oligosaccharide, and polyvinyl alcohol 10~
30 parts, 10~30 parts of methylcellulose, 0.5~5 part of brassin lactones (brassinolide), higher fatty acids (C6~C26's
Monocarboxylic acid) 20~50 parts, 5~20 parts of magnesium sulfate, 5~20 parts of calcium nitrate, 1~5 part of borax, 1~5 part of organosilicon, ammonium molybdate
0.5~2 part, 0.5~2 part of rare-earth fertilizer.
The higher fatty acids is selected from dodecanoic acid, hexadecanoic acid (palmitinic acid), arachic acid (arachidic acid), lignocerane
Any one in acid (lignin acid) or two or more combinations.
The trisiloxanes polyoxyethylene ether organosilicon L-66 of the organosilicon preferred Jinan Lv Sai Chemical Co., Ltd. production.
The rare-earth fertilizer can conventional market be commercially available, the present invention used in rare-earth fertilizer be leavening dough rare earth foliar fertilizer, purchased from packet
Co., Ltd, morning market Ruo Ersi compound fertilizer, Ministry of Agriculture's product code: No. 8861.
The preparation method of watermelon anti-cracking agent of the invention, comprising the following steps:
(1) higher fatty acids is added in the water of 20~50 times of amounts (weight multiple), is added and higher fatty acids equimolar
The alkali (sodium hydroxide) of amount reacts 0.5~2 hour, generates the high fat film for being dissolved in water, spare；
(2) polyvinyl alcohol and methylcellulose are added 50~60 times and measure (quality of polyvinyl alcohol and methylcellulose
50~60 times) water in, be warming up to 80~95 DEG C, heat preservation 1~2 hour (dissolving polyvinyl alcohol and methylcellulose all),
35~40 DEG C are cooled to, is filtered to get filtrate, it is spare；
(3) high fat film is added in filtrate obtained above, chitosan oligosaccharide, magnesium sulfate, calcium nitrate, brassin is then added
Lactone, organosilicon, ammonium molybdate, borax and rare-earth fertilizer, at 35~40 DEG C, stirring and dissolving, filtering (using stainless steel cloth) is obtained for heat preservation
Filtrate, watermelon anti-cracking agent as of the invention.
Watermelon anti-cracking agent of the invention, can effectively prevent watermelon splits melon, it is also possible to be applied to sweet tea as increasing agent
The gourd, fruit and vegetables such as melon, jujube, cherry, tomato, grape.When concrete application, usage mode: 500~1000 are diluted with water, complete stool
It is spraying；The time of infertility sprays 3~5 times: for the first time 5 days before spending, being diluted with water 500 times, the mu medical fluid (medicine after referring to dilution
Liquid, similarly hereinafter) 30 kilograms；In 5~10 days, 800 times are diluted with water, mu is with 45 kilograms of medical fluid after sitting melon for the second time；Third time exists
10 days or so before picking, 800 times are diluted with water, mu is with 45 kilograms of medical fluid.
Watermelon anti-cracking agent of the invention, has the advantages that
1, film forming, diffusivity are excellent: product utilization methylcellulose of the invention, polyvinyl alcohol, chitosan oligosaccharide, organosilicon etc.
Raw material, the techniques such as heated reaction, chelating, makes film forming, dispersibility, scalability, flexibility, translucency, gas permeability, resistance to rainwater
Erosion increases substantially, and 2 hours chance rain does not have to respray after sprinkling；Watermelon anti-cracking agent is sprayed to crop surface (including fruit, leaf
Son, stem) after can diffuse to form the film of one layer of package fruit, leaf or stem in crop surface, play heat and moisture preserving, nutrition be provided etc.
Effect.
2, heat, moisturizing: after sprinkling watermelon anti-cracking agent, plant temperature is improved, the enhancing of the lower temperature resistance of watermelon, leaf, stem,
Flower, fruit growth are normal, and moisturizing, drought resistance improve, melon skin and internal growth basic synchronization.
3, disease-resistant, volume increase, upgrading: due to being added to chitosan oligosaccharide, film forming is not only increased, plant is also added and function is immunized
Can, so that crop is automatically generated resistance to external germ, virus, pest, and shield disease pest signal, prevents disease pest from infecting
Branch, leaf, flower, fruit achieve the purpose that diseases prevention, disease-resistant, insect prevention.Meanwhile also increasing crop self-control growth and absorption equilibrium
Ability.The nutrients such as calcium, magnesium, silicon, boron, molybdenum are scientifically added to again in watermelon anti-cracking agent of the invention, that is, are reduced scarce
Plain disease, and significantly increase the hardness and suppleness of melon skin, finally solves the problems, such as that watermelon splits melon, can make yield, quality with
And prematureness has different degrees of raising.
4, watermelon anti-cracking agent of the invention can be applied to the gourd, fruit and vegetables such as muskmelon, jujube, cherry, tomato, grape simultaneously,
And it may replace fruit cap bag partial function.Entire breeding time sprays 3~5 times, reduction pesticide, Fertilizer application amount 30~80%, and one
As can increase production 10~50%.
