METHOD FOR HIGH-EFFICIENTLY INDUCING DOUBLE STEMS OF

PHALAENOPSIS

FIELD OF THE INVENTION

The present invention relates to the technical field of plant handling, in particular to a method for high-efficiently inducing double stems of Phalaenopsis.

BACKGROUND OF THE INVENTION

Phalaenopsis is a Phalaenopsis genus plant in the Orchid family, known as the "Queen of

Foreign Orchid" with peculiar flower shape, gorgeous color and long-lasting florescence.

The article "Investigating the spiking and double spiking ratio of Phalaenopsis within the air-inflated double-poly envelope inside a plastic greenhouse" published by Liu Yaoren said that after more than 30 days of flower forcing the stem-doubling induction rates of different

Phalaenopsis varieties were 50% of Sunset Red, 27% of Lawrence, 17% of V3, and only 3% of Jubao Red Rose. The article "Why Phalaenopsis is the king of New Year's eve flowers" carried by "China Flower & Gardening News" at the end of March this year said that the amount of the Phalaenopsis put on the market during the New Year's eve in 2020 in China is estimated to exceed 55 million, and the total sales amount is expected to be more than 1 billion yuan, which is the sum of the sales amounts of several other major varieties ranked behind. In the aspect of double-stem phalaenopsis varieties, Europe has a great advantage over China, as European breeders have cultivated double-stem varieties for more than 20 years. For middle and small flower shapes, double-stem varieties are more economical for growers than single-stem varieties. For distribution customers in China, while the buying price of single-stem Phalaenopsis products is 20 yuan, the buying price of high-quality double-stem products is generally 25 yuan at a maximum premium of 25%. Thus, it can be seen that it is of important practical significance to perfect the research of double-stem

Phalaenopsis for improving people's life quality and developing China into a beautiful country.

SUMMARY OF THE INVENTION

In order to solve the above-mentioned technical problems, the present invention provides

DK 2022 70523 A1 2 a method for high-efficiently inducing double stems of Phalaenopsis, which enables people to enjoy the sight of cultivating double-stem varieties, but greatly saves the time and costs required for breeding.

The technical solution of the present invention is as follows.

A method for high-efficiently inducing double stems of Phalaenopsis includes the following steps:

S1. physical processing of plants: uniformly adjusting the physical plane and spatial angle of Phalaenopsis plants to be processed for flower forcing; and

S2. processing with a chemical reagent: after completing S1, spraying a pedicel-inducing mixed solution on the stem segments of 2-5 leaves of the Phalaenopsis plants once every 10 days to 3 times in total; ending with enabling double stems of Phalaenopsis to be high-efficiently induced.

Preferably, in S1, the step of adjusting the physical plane includes arranging all

Phalaenopsis plants toward an identical orientation with the growth direction of the stems and leaves of plants toward north and their roots toward south.

Preferably, in S1, the step of adjusting the spatial angle includes raising the inclination of all the Phalaenopsis plants to be processed for flower forcing to an identical angle, so as to incline the plants toward the bottom surface of a swayed bed at an angle of 70 to 90 degrees and then enable light to strike the leaf axils of the stem segments of 3-5 leaves of the

Phalaenopsis plants from top to bottom, after growing to 10~20cm for pedicels under flower forcing for 30 to 40 days, removing the inclination and returning to arrangements at 0 or 180 degrees.

Preferably, in S2, the pedicel-inducing mixed solution includes TDZ (0.01~0.05g/L)+

GA3(0.3~1.0g/L)+IAA(0.1~0.6g/L)+PP333(0.2~0.8g/L)+P205(0.5~1.2g/L)+ glutamic acid (0.8~1.5g/L).

Preferably, in S2, the spraying method includes using a 150ml small sprinkler each time, and adjusting its mouth to the best state of forming mists applied in one cycle around the stem segments of 2-5 leaves of the Phalaenopsis plants, with stress on spraying the leaf axils of the plants, after spraying, it is suitable that the water mists adhere to the surface of the stem segments and does not flow.

Preferably, in S2, the pedicel-inducing mixed solution is applied once every 9-12 days to

DK 2022 70523 A1 3 2-4 times in total.

The present invention has beneficial effects as follows. 1. Plants can be processed simply and effectively outdoor, and the double stems of

Phalaenopsis can be induced periodically. 2.The adjustment of the physical plane of the Phalaenopsis plants can not only make earth's magnetic field pass through the plant bodies smoothly, but also minimize the impact of the magnetic field on the plant, facilitating the operations such as fertilizing, watering and changing pots. 3.The adjustment of the physical spatial angle of the Phalaenopsis plants helps light to strike on the leaf axils of the stem segments of 3-5 leaves of the Phalaenopsis plants from top to bottom, promoting the germination of double stems. 4.The chemical processing can effectively boost the plants to change form vegetative growth to reproductive growth, and promote flower-bud differentiation and double stem rate, so it is of great significance in large-scale production.

DETAILED DESCRIPTION OF SOME EMBODIMENTS

In order to make the objective, technical solution and advantages of the present invention clearer, we will further detail the present invention in combination with the examples as follows, however, it should be understood that the specific examples described

DK 2022 70523 A1 4 herein are only used to explain the present invention, but not to pose any limitation on the present invention.

Example I 1. Physical Processing of Plants:

In order to promote the germination of double stems smoothly and effectively, we physically process the Phalaenopsis plants in advance, that is, uniformly adjust the physical plane and spatial angle of the Phalaenopsis plants to be processed for flower forcing. Firstly, the step of adjusting the physical plane includes arranging all Phalaenopsis plants toward an identical orientation, this trial greenhouse is in the north-south orientation(other similar greenhouses can be adjusted according to the actual situation), which orientates the growth direction of the stems and leaves of the plants toward north and its roots toward south, not only guaranteeing the growth of the plants along the earth's magnetic field and the minimization of the impact of the magnetic field on the plant, but also facilitating the operations such as fertilizing, watering and changing pots (see FIG. 1). Secondly, the step of arranging all Phalaenopsis plants toward an identical orientation is followed by the step of adjusting the spatial angle, which includes raising the inclination of all the Phalaenopsis plants to be processed for flower forcing to an identical angle, so as to incline the plants toward the bottom surface of a swayed bed at an angle of 70 to 90 degrees and then enable light to strike the leaf axils of the stem segments of 3~5 leaves of the Phalaenopsis plants from top to bottom, after growing to 10~20cm for pedicels under flower forcing for 30 to 40 days, removing the inclination and returning to the arrangement at 0 or 180 degrees (see

FIG 2). The detailed experimental results are shown in Tables 1-3.

According to the statistical analysis after 30 days, the stem-doubling induction results of the Phalaenopsis plants processed toward an identical orientation show that: no inducted double stem occurs in the Phalaenopsis grandiflora in the group P1 only processed toward an identical orientation, as 0% as a stem-doubling induction rate; 5 inducted double stems occur in the Phalaenopsis floweret in the group P2 processed toward an identical orientation, as 5.6% as a stem-doubling induction rate; no inducted double stem still occurs in the

Phalaenopsis grandiflora in the control group P3, as 0% as a stem-doubling induction rate; and 1 inducted double stem occurs in the Phalaenopsis floweret in the control group Pa, as 1.1% as a stem-doubling induction rate (see Table 1).

DK 2022 70523 A1

According to the statistical analysis after 30 days, the stem-doubling induction results of the Phalaenopsis plants spatially inclined at an angle show that: 4 inducted double stems occur in the Phalaenopsis grandiflora in the group Ps only spatially inclined at an angle of 70 to 90 degrees, as 4.4% as a stem-doubling induction rate; 9 inducted double stems occur in the Phalaenopsis floweret in the group Ps spatially inclined at an angle of 70 to 90 degrees, as 10.0% as a stem-doubling induction rate; the Phalaenopsis grandiflora in the group Ps has 4 double stems more than that in the control group P3, with the stem-doubling induction rate increased by 4.4%, and the Phalaenopsis floweret in the group Ps has 8 double stems more than that in the control group Pa, with the stem-doubling induction rate increased by 8.9% (see Table 2).

According to the statistical analysis after 30 days, the stem-doubling induction results of the Phalaenopsis plants processed toward an identical orientation and spatially inclined at an angle show that: 71 inducted double stems occur in the Phalaenopsis grandiflora in the group

P7 processed toward an identical orientation and spatially inclined at an angle of 70 to 90 degrees, as 78.9% as a stem-doubling induction rate; 82 inducted double stems occur in the

Phalaenopsis floweret in the group Ps processed toward an identical orientation and spatially inclined at an angle of 70 to 90 degrees, as 91.1% as a stem-doubling induction rate; the

Phalaenopsis grandiflora in the group P7 has 71 double stems more than that in the control group Ps, with the stem-doubling induction rate increased by 78.9%, and the Phalaenopsis floweret in the group Ps has 81 double stems more than that in the control group P4, with the stem-doubling induction rate increased by 90% (see Table 3).

It can be seen from Table 3 that regardless of whether the phalaenopsis plants processed toward an identical orientation and spatially inclined at an angle belong to grandiflora or floweret, they have an improvement in the aspects of the number of inducted double stems and the stem-doubling induction rate. The Phalaenopsis floweret in the group Ps has 82 double stems more than the phalaenopsis grandiflora in the control group Ps with the stem-doubling induction rate increased by 91.1%, 81 double stems more than the phalaenopsis floweret in the group Ps with the stem-doubling induction rate increased by 90%, and 11 double stems more than the phalaenopsis grandiflora in the group P7 with the stem-doubling induction rate increased by 15.4%. The Phalaenopsis grandiflora in the group

P7 has 71 double stems more than the phalaenopsis grandiflora in the control group P3 with the stem-doubling induction rate increased by 78.9%, and 70 double stems more than the phalaenopsis floweret in the group Ps with the stem-doubling induction rate increased by

DK 2022 70523 A1 7 77.8%. It can be seen from the above that the processing toward an identical orientation and the spatial inclination at an angle play an important role in inducing double stems of

Phalaenopsis. 2. Processing of Plants with a Chemical Reagent

The research on the processing of plants with a chemical reagent includes, after completing the step of uniformly adjusting the orientation and spatial angle, spraying the pedicel-inducing mixed solution (TDZ(0.01~0.05g/L)+GA3(0.3~1.0g/L)+IAA(0.1~0.6g/L)+

PP333(0.2-0.89/L)+P205(0.5-1.2g/L)+glutamic acid(0.8-1.5g/L)) on the stem segments of 2-5 leaves of the Phalaenopsis plants, meanwhile stetting up a control group (without the pedicel-inducing mixed solution sprayed thereon). 30 pots of plants pertain to each processing, repeatedly trialed 3 times. They are processed with the pedicel-inducing mixed solution once every 10 days to 3 times in total. The spraying method includes using a 150ml small sprinkler each time, and adjusting its mouth to the best state of forming mists applied in one cycle around the stem segments of 2-5 leaves of the Phalaenopsis plants, with stress on spraying the leaf axils of the plants, after spraying, it is suitable that the water mist adheres to the surface of the stem segments and does not flow. The trial results show that the stem-doubling induction rate of the plants sprayed with the pedicel-inducing mixed solution is 98.9% for floweret, 88.9% for grandiflora, so the stem-doubling induction rate of floweret is 10% higher than that of grandiflora, and the average stem-doubling induction rate of floweret and grandiflora is 93.9%,but the stem-doubling induction rate of the plants without the pedicel-inducing mixed solution spayed thereon is quite low. The detailed trial results are shown in Table 4, wherein,

DK 2022 70523 A1 9 uniformly adjusting the orientation and spatial angle shows that: the number of the inducted double stems of the Phalaenopsis grandiflora in the group Po is 72, as 80% as a stem-doubling induction rate, the pedicel length is 10.9cm and the pedicel diameter is 0.41cm; the number of the inducted double stems of the Phalaenopsis floweret in the group Pio is 81, as 90% as a stem-doubling induction rate, the pedicel length is 8.6cm and the pedicel diameter is 0.31cm.

According to the statistical analysis after 30 days, the result of spraying the pedicel-inducing mixed solution B on the Phalaenopsis plant after completing the step of uniformly adjusting the orientation and spatial angle shows that: the number of the inducted double stems of the Phalaenopsis grandiflora in the group Pu is 73, as 81.1% as a stem-doubling induction rate, the pedicel length is 9.2cm and the pedicel diameter is 0.45cm; the number of the inducted double stems of the Phalaenopsis floweret in the group P12 is 82, as 91.1% as a stem-doubling induction rate, the pedicel length is 7.7cm and the pedicel diameter is 0.35cm.

According to the statistical analysis after 30 days, the result of spraying the pedicel-inducing mixed solution C on the Phalaenopsis plant after completing the step of uniformly adjusting the orientation and spatial angle shows that: the number of the inducted double stems of the Phalaenopsis floweret in the group Pia is 89, as 98.9% as a stem-doubling induction rate, the pedicel length is 10.5cm and the pedicel diameter is 0.38 cm (see FIGs.3, 6 and 7); the Phalaenopsis grandiflora in the group P13 comes second, the number of its inducted double stems is 80, as 88.9% as a stem-doubling induction rate, the pedicel length is 12.8cm and the pedicel diameter is 0.52cm (see FIGs.4, 5 and 8).

According to the statistical analysis after 30 days, the result of spraying the pedicel-inducing mixed solution D on the Phalaenopsis plant after completing the step of uniformly adjusting the orientation and spatial angle shows that: the number of the inducted double stems of the Phalaenopsis grandiflora in the group Pis is 70, as 77.8% as a stem-doubling induction rate, the pedicel length is 7.9cm and the pedicel diameter is 0.39cm; the number of the inducted double stems of the Phalaenopsis floweret in the group Pisis 80, as 88.9% as a stem-doubling induction rate, the pedicel length is 6.6cm and the pedicel diameter is 0.25cm.

It can be seen from Table 4 that: after completing the step of uniformly adjusting the orientation and spatial angle, the effect of spraying the pedicel-inducing mixed solutions

DK 2022 70523 A1 (TDZ(0.01~0.05g/L)+GA3(0.3~1.0g/L)+TAA(0.1~0.6g/L)+PP333(0.2~0.8g/L)+P205(0.5~1.2¢ /L)t+glutamic acid (0.8~1.5g/L)) on the Phalaenopsis plants is the best in the aspect of whether the number of the induced double stems or the improvement of the induction rate.

Among them, the Phalaenopsis floweret in the group P14 has the best induction effect with the maximum number of 89 inducted double stems, and the induction rate up to 98.9%, the pedicel length is 10.5cm and the pedicel diameter is 0.38cm (see FIGs.3, 6 and 7). The

Phalaenopsis grandiflora in the group P13 comes second, the number of its inducted double stems is 80, as 88.9% as a stem-doubling induction rate, the pedicel length is 12.8cm and the pedicel diameter is 0.52cm (see FIGs.4, 5 and 8). Compared with P3,P4,P9,P10,P11,P12,P13,P15 and Pi6, the number of the inducted double stems of the Phalaenopsis floweret in the group

P14 rises by 89, 88 as a rate of increase as 8800%, 17 as a rate of increase as 23.6%, 8 as a rate of increase as 9.9%, 16 as a rate of increase as 21.9%, 7 as a rate of increase as 8.5%, 9 as a rate of increase as 11.3%, 19 as a rate of increase as 24.1% and 9 as a rate of increase as 11.3%, respectively; its stem-doubling induction rate increases by 98.9%, 97.8%, 18.9%, 8.9%, 17.8%, 7.8%, 10.0%, 21.1% and 10.0%, respectively; its pedicel length rises by 10.5cm, Scm as a rate of increase as 91%, -0.4cm as a rate of decrease as 3.7%, 1.9cm as a rate of increase as 22.1%, 1.3cm as a rate of increase as 14.1%, 2.8cm as a rate of increase as 36.4%, -2.3cm as a rate of decrease as 18.0%, 2.6cm as a rate of increase as 32.9% and 3.9cm as a rate of increase as 59.1%, respectively; its pedicel diameter rises by 0.38cm, 0.15cm as a rate of increase as 65.2%, -0.03cm as a rate of decrease as 7.3%, 0.08cm as a rate of increase as 26.7%, -0.07cm as a rate of decrease as 15.6%, 0.03cm as a rate of increase as 8.6%, -0.14cm as a rate of decrease as 26.9%, -0.01cm as a rate of decrease as 2.6% and 0.13cm as a rate of increase as 52%, respectively. It can be seen from the above that the slight partial disadvantage of the floweret in comparison with the grandiflora in the aspects of the pedicel length and pedicel diameter depends on the characteristics of the varieties themselves; but the floweret has an absolute advantage in the aspects of the key indexes, the number of inducted double stems and the stem-doubling induction rate. Compared with

P3,P4,Po P10,P11,P12,P13,P15s and Pis, the number of the inducted double stems of the

Phalaenopsis grandiflora in the group P3 rises by 80, 79 as a rate of increase as 7900%, 8 as a rate of increase as 11.1%, -1 as a rate of decrease as 1.2%, 7 as a rate of increase as 9.6%, -2 as a rate of decrease as 2.4%, -9 as a rate of decrease as 10.1%, 10 as a rate of increase as

DK 2022 70523 A1 11 14.3% and 0 as a rate of increase as 0.0%, respectively; its stem-doubling induction rate increases by 88.9%, 87.8%, 8.9%, -1.1%, 7.8%, -2.2%, -10.0%, 11.1% and 0.0%, respectively; its pedicel length rises by 12.8cm, 7.3cm as a rate of increase as 132.7%, 1.9cm as a rate of increase as 17.4%, 4.2cm as a rate of increase as 48.8%, 3.6cm as a rate of increase as 39.1%, 5.1cm as a rate of increase as 66.2%, 2.3cm as a rate of increase as 21.9%, 4.9cm as a rate of increase as 62.0% and 6.2cm as a rate of increase as 93.9%, respectively; its pedicel diameter rises by 0.52cm, 0.29cm as a rate of increase as 126.1%, O0.11cm as a rate of increase as 26.8%, 0.22cm as a rate of increase as 73.3%, 0.07cm as a rate of increase as 15.6%, 0.17cm as a rate of increase as 48.6%, 0.14cm as a rate of increase as 36.8%, 0.13cm as a rate of increase as 33.3% and 0.27cm as a rate of increase as 108.0%, respectively. It can be seen from the above that the grandiflora has an obvious disadvantage in comparison with the floweret in the aspects of the number of inducted double stems and the stem-doubling induction rate, but has an advantage in the aspects of the pedicel length and the pedicel diameter.

In summary, the method of applying the pedicel-inducing mixed solutions after completing the step of uniformly adjusting the orientation and spatial angle plays a crucial role in the induction of double stems of Phalaenopsis, not only achieving a "zero" breakthrough (Phalaenopsis grandiflora), but also significantly increasing the number of the inducted double stems and raising the stem-doubling induction rate. In addition, the method also has an obvious advantage in increasing the pedicel length and pedicel diameter as a solid technical foundation in the aspects of cultivating high-yield, high-quality and efficient phalaenopsis and beautifying environments for people’s yearning life.

The above description is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modifications, equivalent replacements and improvements made by any person skilled in the art within the technical scope disclosed by the present invention shall fall within the protection scope of the present invention.
