Description
Technical Field
The invention relates to the technical field of fruit tree pollination, in particular to a device and a method for adjusting fruit setting rate of fruit trees through position flow double-control liquid pollination.
Background
Plant self-incompatibility is a mechanism that is common in angiosperms to limit self-fertilization and prevents normal growth and fertilization of pollen tubes of the same genotype in pistils. The reaction involves more than 70 families and more than 250 genera. The occurrence of self-incompatibility prevents inbreeding, promotes cross pollination and fertilization, and is beneficial to species diversity. The types of self-incompatibility can be classified into sporophyte and gametophyte according to their control factors. Gametophytic self-incompatibility means that during the interaction of pollen and pistil, the behavior of pollen is determined by the nature of the protein in the inner wall of the pollen grain, i.e. by the haploid genotype of the pollen grain itself, and various fruit trees of the rosaceae family such as pear, apple, sweet cherry, apricot, prune, plum, almond, etc. exhibit gametophytic self-incompatibility. The phenomenon of self-incompatibility has driven the evolution of species to some extent, but has also posed a barrier in the production of commercial crops such as apple production. Because the self-pollination of the fruit trees can not be carried out, pollination varieties are required to be configured in production, and the fruit setting can be ensured by artificial supplementary pollination, so that the production cost is increased. However, after pollination is completed, the number of general fruits is far more than the production requirement, the quality of the fruits can not be ensured, and flower and fruit thinning can only be performed again. Flower thinning and fruit thinning are necessary measures for improving fruit setting rate and fruit quality of fruit trees, and are important for improving high and stable yield of orchards and improving fruit quality. In the prior art, the flower and fruit thinning operation is completely dependent on manual operation, a large amount of labor force is needed, and the manual flower and fruit thinning operation becomes a bottleneck problem limiting the benefits of an orchard along with the increase of labor cost. The chemical flower and fruit thinning has low cost, but the effect is extremely unstable, and the chemical flower and fruit thinning cannot be popularized in a large area for many years. How to balance the contradiction between the two, realize the double regulation and control of pollination and fruit setting, and realize the light simplified cultivation, which is the starting point of the invention.

Detailed Description
It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
As described in the background art, most fruit trees are cross pollinated, and if the pollinated pollen quantity can be controlled, the flower thinning and fruit thinning problems of the fruit trees can be fundamentally solved.
The invention provides a single variety garden construction method, which uses a position flow double-control sprayer nozzle for liquid pollination, and adjusts the liquid pollination concentration according to the expected yield, so that the method for regulating the fruit setting rate of the fruit trees in the flowering phase is one-step in place, and flower and fruit thinning is not needed, and the method is suitable for most cross-pollinated fruit trees, especially for large fruit trees such as apples, pears, cherries and the like.
The invention discloses a position flow double-control liquid pollination spraying device, which comprises a liquid storage barrel (2) and a spray rod (8) connected with the liquid storage barrel, wherein at least one spray head (7) is arranged on the spray rod (8); a protective cover (13) is arranged on the spray head (7); one end of the protective cover (13) is fixed on the spray rod (8), and the other end of the protective cover is open; one end of the opening of the protective cover (13) is provided with a shutter cover (12).
Further, a plurality of spray heads (7) are arranged on the spray rod (8), and the intervals among the spray heads (7) are 40-50 cm.
Further, a plurality of fan blades (14) are arranged on the shutter cover (12); the fan blades (14) are movably connected with a longitudinal fan blade shaft (11).
Further, the lower end of the fan blade shaft (11) is movably connected with a chute (9) fixed at the outer edge of the protective cover (13), and a fastening bolt (10) is arranged on the chute (9).
Further, the bottommost part of the opening end of the protective cover (13) is connected with the solution backflow branch pipe (5).
Further, the solution reflux branch pipe (5) is connected with the multi-way joint (4), and one end of the multi-way joint (4) is connected with the liquid storage barrel (2) through the solution reflux main pipe (3).
The double control of the position and the flow rate is realized by the following method: the length of the spray boom and the number of the spray heads are determined according to the height of the fruit tree to be pollinated and the distribution position of flowers, the angle of the fan blades on the shutter cover is adjusted according to the distribution position of the flowers and the load of the fruit tree, and the concentration of pollen in the liquid pollinating liquid is adjusted according to the fruit setting rate which is required to be achieved.
The liquid pollination liquid disclosed by the invention comprises the following raw materials in parts by weight: 4-10 parts of pollen, 4-6 parts of Xanthomonas polysaccharide, 120-180 parts of sucrose, 10-15 parts of borax and 10000 parts of water. Wherein the Xanthomonas polysaccharide can be rapidly dissolved in water, and has good water solubility. Particularly can be dissolved in cold water, can save complicated processing procedures and is convenient to use. However, because of its extremely strong hydrophilicity, if water is directly added and stirring is insufficient, the water is absorbed by the outer layer and swells into a micelle, which can prevent the water from entering the inner layer, thereby affecting the effect. Typically, one part of Xanthomonas polysaccharide is mixed with ten or more other dry materials, such as sugar, monosodium glutamate, salt, etc. in food preparation, and then slowly poured into stirring water, soaked for about two hours, and stirred continuously until completely dissolved. This allows for even mixing in the solution without sinking into the bottom of the liquid after the pollen is added.
In order to enable those skilled in the art to more clearly understand the technical solutions of the present application, the technical solutions of the present application will be described in detail below with reference to specific embodiments.
The test materials used in the examples of the present invention are all conventional in the art and are commercially available.
Examples:
preparing a liquid pollination liquid: 6g of xanthomonas polysaccharide and 180g of sucrose are uniformly mixed in advance, 10Kg of hot water at 70 ℃ is slowly added for dissolution, 10g of borax is added, stirring is carried out simultaneously, standing is carried out for half an hour after uniform stirring, 4g of pure crab pollen is added according to the proportion after cooling to room temperature, and the mixture is added into a liquid storage barrel after uniform mixing.
Pollination of fruit trees:
checking whether the joints of the spraying device leak air or not, and pouring the prepared liquid pollination liquid into the liquid storage barrel (2).
And selecting a Fuji apple tree with the height of 3m as a target fruit tree, determining 4 spray heads (7) according to the height of the target fruit tree and the number of flowers and fruits on the fruit tree, and enabling a spray rod (8) to be 2m long. According to the assessment of the flower quantity of the fruit tree in the garden, the flower fruit setting rate is determined to be 30%, and the inflorescence fruit setting rate is determined to be 90%.
According to the determined spraying range, the opening and closing angles of the fan blades (14) on the shutter cover (12) are adjusted by moving the fan blade shaft (11) up and down, so that the purposes of controlling the spraying range and the spraying angle of the liquid pollination liquid are realized. After the angle is adjusted, the position of the fan blade shaft (11) is fixed through the fastening bolt (10), so that the fan blade shaft (11) is fixed on the chute (9), the upward and downward movement of the fan blade shaft is avoided, and the opening and closing angle of the fan blade (14) is prevented from being changed due to the impact of liquid pollination liquid.
The switch (1) of the spraying device is turned on, the liquid pollination liquid enters the spray rod (8), the switch (6) of the spray head to be used is turned on, and the liquid pollination liquid is sprayed out of the spray head (7) in a spray form. Some of the liquid pollination liquid sprayed from the spray head (7) is blocked by the fan blades (14) and cannot be sprayed. The liquid pollination liquid which is not sprayed out is blocked inside the protective cover (13) and flows to the bottommost end in the protective cover (13). The reflux branch pipe (5) connected to the bottommost end of the protective cover (13) is converged to the reflux main pipe (3) through the multi-way joint (4) and flows back into the liquid storage barrel (2), so that the waste of liquid pollination liquid is avoided.
If 30 meters are provided in adjacent orchards, an insect-proof net can be arranged in the flowering phase to prevent exogenous pollen interference;
after the spraying operation is finished, the switch (1) of the spraying device is closed, the residual liquid pollination liquid in the barrel is poured out, then the liquid pollination liquid is cleaned by clean water, inverted and dried, and other parts are also cleaned by clean water and then are placed in a cool place for drying. When the product is not used any more in a short period, the main components should be cleaned, wiped and dried, and then placed in a cool and dry place; if the metal parts are not used for a long time, the metal parts are coated with butter, so that rust is prevented.

test example 2. Influence of liquid pollination on fruit setting rate and quality:
three groups of liquid pollination solutions with the prepared pollen concentrations of 0.03%, 0.04% and 0.05% are used for pollination of four-year-old Fuji fruit trees in Jining Wen Shangxian county, each group is repeated three times, natural pollination is used as a control, and the specific experimental results are as follows:
(1) Influence of liquid pollination on fruit setting rate:
table 3:
as shown in table 3, when the pollen concentration in the liquid pollination liquid is 0.03%, the fruit setting rate is obviously reduced compared with the control; when the pollen concentration in the liquid pollination liquid is 0.04% and 0.05%, the fruit setting rate can be obviously increased compared with the control.
(2) Influence of liquid pollination on fruit weight per fruit:
table 4:
from table 4, liquid pollination at different pollen concentrations had no significant effect on fruit single fruit weight.
(3) Effect of liquid pollination on fruit hardness:
table 5:
from table 5, liquid pollination at different pollen concentrations had no significant effect on fruit firmness.
(4) Effect of liquid pollination on fruit soluble solids:
table 6:
from Table 6, liquid pollination with different pollen concentrations can increase the soluble solids content of the fruit; however, the concentration of pollen is different, and the content of soluble solids in fruits is not obviously different.
(5) Influence of liquid pollination on the Vc content of the fruit:
table 7:
from Table 7, liquid pollination at different pollen concentrations had no significant effect on the Vc content of the fruit.
(6) Effect of liquid pollination on the soluble sugar content of the fruit:
table 8:
from Table 8, liquid pollination with different pollen concentrations can increase the soluble sugar content of the fruit; however, the concentration of pollen is different, and the content of soluble sugar in fruits is not obviously different.
(7) Effect of liquid pollination on fruit titratable acid content:
table 9:
from table 9, liquid pollination with different pollen concentrations can reduce the titratable acid content of the fruit; as pollen concentration increases, the titratable acid content of its fruit increases slightly.
(8) Influence of liquid pollination on anthocyanin content of pericarp:
table 10:
from Table 10, liquid pollination with different pollen concentrations can increase the anthocyanin content of the pericarp; however, the pollen concentration is different, and the anthocyanin content of the peel is not obviously different.
In summary, liquid pollination can regulate fruit setting rate by controlling pollen concentration in pollination liquid, and as pollen concentration increases, fruit setting rate also increases; the liquid pollination can also improve the content of soluble sugar and anthocyanin in the fruit, reduce the content of titratable acid in the fruit, and improve the quality of the fruit such as flavor, color and the like.
