Description
Technical field
The invention belongs to field of planting, be specifically related to a kind of early crisp red pear liquid pollination agent.
Background technology
Pears are self-pollination sterility fruit trees, must plant pollinizers aborning or artificial supplementary pollination could obtain corresponding yield and quality.Planting pollinizers mainly utilizes the pollination ability of insecticide to carry out spontaneous pollination, although save labor, but is easy to be subject to the impact of weather to cause Pollination Fertilization bad.Increasing theatre adopts artificial supplementary pollination in recent years.Although the mode selectivity that in artificial supplementary pollination method, artificial point is awarded is strong, accuracy rate is high, and pollen consumption is little, but operable time is short, and recruitment is many, and production cost is higher.Additionally, the method that human assistance solid dusts there is also pollen consumption greatly, relatively costly problem.Liquid pollination is a kind of novel pollination technique, has pollination speed fast, saves artificial feature, and can increase moisture and the nutrient of stigma, extends the stigma Pollination Fertilization time.But liquid pollination technology is still immature, however it remains nutritional solution suspending power poor, pollen dispersion is uneven, the urgent problem such as swelling death in nutritional solution.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of early crisp red pear liquid pollination agent, composition and compound method to liquid pollination agent have improved, and solve the easy swelling death of pollen, disperse uneven, and the problem that conventional liq pollination agent cost is high, service efficiency is low.
The present invention is achieved through the following technical solutions:
A kind of early crisp red pear liquid pollination agent, is made up of the material of following weight portion:
500 ~ 700 parts of sucrose, 3 ~ 7 parts of potassium dihydrogen phosphates, 2 ~ 5 parts of calcium nitrates, 2 ~ 3 parts of amino-acid chelates, 1.2 ~ 2.4 parts of guar gum, 0.3 ~ 1 part of ethylenediaminetetraacetic acid, 1 ~ 2 part of pear flower pollen particles, 1 ~ 2 part of boric acid, 1 ~ 2 part of compound vitamin, 2000 ~ 2400 parts of water；
Its preparation method comprises the steps:
(1) choose the petal that outward appearance is good, a bud just ready to burst, put in vial standby after flower pesticide being taken out with the tweezers after sterilization；
(2) when the flower pesticide chosen being placed on 20 ~ 25 DEG C, and slowly rub, after the pollen in flower pesticide ejects, then with 120 order dusting covers, impurity is sifted out, retain pear flower pollen particles standby；
(3) when pear flower pollen particles being placed on 23 ~ 26 DEG C, keeping relative air humidity is 80 ~ 90%, stand after moisture absorption 2 ~ 3h until it, add the guar gum of its gross mass 1.2 times, and blast warm wind, controlled wind speed is 8 ~ 10m/s, after continuing 5 ~ 10min mix homogeneously, obtains arogel mixture standby；
(4) 500 ~ 700 portions of sucrose, 3 ~ 7 parts of potassium dihydrogen phosphates, 2 ~ 5 parts of calcium nitrates, 2 ~ 3 parts of amino-acid chelates, 1 ~ 2 part of boric acid, 1 ~ 2 part of compound vitamin are joined in 2000 ~ 2400 parts of water, it is to slowly warm up to 20 ~ 23 DEG C, period does not stop stirring, after mentioned component fully dissolves, again arogel mixture is passed in aqueous solution with the speed of 4.5 ~ 5.5m/s, finally water solution mixture is placed in ultrasonic Treatment instrument and processes 60 ~ 80s namely obtains liquid pollination agent.
Further, described amino-acid chelate is made up of zinc-amino acid chelate, calcium amino acid chelate, chelating amino acids molybdenum, iron-amino acid chelate.
Further, containing vitamin B, vitamin C, vitamin E in described compound vitamin.
Further, the temperature of the warm wind described in step (3) is 23 ~ 26 DEG C.
Further, the frequency of the ultrasonic Treatment described in step (4) is 30 ~ 33KHz.
There is advantages that
(1) by after pear flower pollen particles moisture absorption, itself and guar gum are stirred by the warm wind of recycling large wind, can make guar gum granule uniform adsorption on pear flower pollen particles, improve the scattered uniformity of pollen particles, then the arogel mixture of gained is passed in aqueous solution with the speed of 4.5 ~ 5.5m/s, the guar gum granule being adsorbed on pollen particles absorbs water rapidly, formed one by one each other scattered appearance have sticking bulk granule, improve pollen particles uniformity in liquid solution and suspension, pass into that speed is too high or too low all can reduce pollen particles uniformity in liquid solution and stability.
(2) interpolation of potassium dihydrogen phosphate, calcium nitrate, amino-acid chelate, compound vitamin and boric acid is not only pollen sprouting on gynoecium and provides required nutrient substance, and can penetrate in pollen cell when ultrasonic Treatment, improve the activity of pollen, ensure that pollination success rate, ethylenediaminetetraacetic acid can eliminate the heavy metal impact on enzyme after being absorbed by plant, further increase efficiency and the success rate of pollination, additionally, ultrasonic Treatment further increases pollen particles scattered uniformity in liquid flux.
(3) form that the pear flower pollen particles of fluid present invention pollination agent wraps one layer of sticky gum with outer layer is dispersed in liquid solution, overcome in common liq pollination agent problems such as easily mutually sticking between pollen particles, block shower nozzle, inequality of dusting, consumption are excessive, and pollen particles attachment dynamics on gynoecium can be strengthened, improve pollination rate, even if meeting with rainy weather after pollination, its effect is not significantly reduced.
(4) the liquid pollination agent of the present invention is compared with other pollination agent and pollinating method, has the advantages that instant effect, pollination rate height, production and labour cost are low, and the impact by natural environmental condition is less, has good promotional value.
Detailed description of the invention
Embodiment 1
A kind of early crisp red pear liquid pollination agent, is made up of the material of following weight portion:
600 parts of sucrose, 5 parts of potassium dihydrogen phosphates, 2 parts of calcium nitrates, 3 parts of amino-acid chelates, 1.2 parts of guar gum, 0.5 part of ethylenediaminetetraacetic acid, 1 part of pear flower pollen particles, 2 parts of boric acid, 1.2 parts of compound vitamines, 2200 parts of water；
