Abstract
The invention relates to an anti-cold inducing agent for vegetables and a using method thereof. The anti-cold inducing agent contains calcium chloride (CaCl2) 10mmol.L-1, magnesium chloride (MgCl2) 3mmol.L-1, abscisic acid (ABA) 0.1mmol.L-1, and the balance water for constant volume. The anti-cold inducing agent is suitable for winter and spring seedling raising or sunlight greenhouse cultivation of thermophilic vegetable crops such as cucumbers and tomatoes. The using time arrangements include that the anti-cold inducing agent is used for seedling raising between November each year and February next year and sprayed when each seedling has two leaves and one core to three leaves and one core, spraying is performed each day and carried out for two continuous days, or the anti-cold inducing agent is used in 3 days prior to cold current after field planting to February next year, and the anti-cold inducing agent is used for once at an interval of 20-30 days and is used for 2-3 times in total. Reagents used by the anti-cold inducing agent are plant hormone and plenty of elements necessary for growth of the vegetables, the costs are low, pollution is avoided, not only is cold resistance of the cucumbers remarkably improved, but also mineral content of the cucumbers can be improved, and product nutrition quality is improved.
Description
One) technical field
The present invention relates to anti-cold derivant of a kind of vegetables and method for using thereof, belong to facilities vegetable culture technique field.
(2) background technology
Greenhouse by solar heat is the main body facility that the north China vegetables produce; Because current structure is simpler and cruder, the ambient controlled degree is low, and winter-spring season is indoor often to be in low temperature and poor light or the inferior suitable warm luminous environment; Cause physiological metabolism processes such as facilities vegetable photosynthesis to be suppressed; Undergrowth, output and kind descend, and further encourage damage by disease and insect and take place, and become the critical limitation of the vegetables sustainable development factor that influences.Improve or induction of resistance is considered to alleviate adverse circumstance causes harm a Critical policies and approach.In recent years, relevant induction of resistance Mechanism Study has obtained many useful result, and progressively obtains the application of producing.Discover abscisic acid (ABA), salicylic acid (SA), calcium chloride (CaCl
2), gibberellin (GA), methyl jasmonate (JA), brassinosteroid (BRs) etc. all participates in the adjusting of many abiotic stresses, improves the resistance of multiple abiotic stress.This is for slowing down low temperature adverse circumstance obstacle, and improving greenhouse by solar heat crop yield and quality provides effective way.Therefore, anti-cold derivant and complex preparation thereof that screening effect is good, effect is stable are set up rational resistance and are induced application technology, will help bringing into play the advantage of plant resistance to environment stress derivant in abiotic stress, in industrialized agriculture, are with a wide range of applications.
(3) summary of the invention
In order to address the above problem, the present invention at first identifies the effect of multiple cold inducer, filters out 5 kinds of anti-cold effective single preparations, and confirms the working concentration that it is suitable; It is composite to be divided into multiple combination then, makes an experiment and cold resistance is identified again, finishing screen is selected the preparation with anti-cold synergistic effect, processes this anti-cold derivant after composite.
The objective of the invention is: to often meeting with the low temperature adverse circumstance in the current Vegetable Production in Solar Greenhouse; Cause poor growth, photosynthetic receiving pressed down problems such as yield and quality reduction; Anti-cold derivant of development vegetables and method for using provide safe and effective cultivation step for alleviating low temperature adverse circumstance obstacle.
A kind of
Vegetables resist cold derivant, contain calcium chloride (CaCl
2), magnesium chloride (MgCl
2) and abscisic acid (ABA), its concentration is respectively: calcium chloride (CaCl
2) 10 mmolL
-1, magnesium chloride (MgCl
2) 3 mmol L
-1And abscisic acid (ABA) 0.1 mmolL
-1, all the other water constant volumes.
During use, spray plant leaf blade, can make the warm season vegetable crop, prolong more than 3 days like lethal time under 5 ℃ of low temperature such as cucumber, tomato winter or early spring.
A kind of
The method for using of the anti-cold derivant of vegetables, may further comprise the steps:
1. vegetables resist cold derivant: 10 mmolL
-1CaCl
2+ 3 mmolL
-1MgCl
2+ 0.1 mmolL
-1ABA
2. service time and access times: used when November ~ next year, grew seedlings February, spray during seedling 2 leaves 1 heart ~ 3 leaves, 1 heart, every day 1 time, connect and sprayed 2 days; Or cold current arrives to use in preceding February in 3 days ~ next year after field planting, winter (December ~ February) at interval 20 ~ 30 days with 1 time, shared 2 ~ 3 times.
Above-mentioned key technique provided by the invention is applicable to winter-spring season cold bed, little shed, big arch shed and vegetables in day-light greenhouse is grown seedlings and the winter-spring season Vegetable Production in Solar Greenhouse.
Beneficial effect:
1, agents useful for same of the present invention is necessary plant hormone of vegetable growth and macroelement, and cost is low, and is pollution-free, not only significantly strengthens the cucumber cold resistance, can also improve its content of mineral substances, improves the product nutritional quality.
2, can prevent that cold current produces low temperature harm to vegetables first service time provided by the invention, can guarantee whole winter vegetable well-grown again, improve quality and improve output.
3, blanking time provided by the invention and access times are on the basis of test of many times, to propose, and can reach anti-cold effect, can guarantee that again seedling or plant do not receive poisoning, and use cost is low.
4, method for using provided by the invention proposes after excuting a law relatively with root, and this method beguine excutes a law simply, convenient, and consumption is few, and cost is low, and is anti-cold effective, yield of vegetables height, quality better.
(4) description of drawings
Fig. 1 is anti-cold derivant of a kind of vegetables and method for using flow chart thereof
1 is to grow seedlings by conventional method among Fig. 1; The 2nd, the preparation of anti-cold derivant promptly takes by weighing powdery CaCl by weight 185:102:41
2, MgCl
26H
2O and ABA and mixing; The 3rd, be diluted with water to CaCl
2Final concentration is 10 mmolL
