Description

Flower increasing agent for increasing flower quantity of passion fruit of pawpaw as well as use method and application of flower increasing agent

Technical Field

The invention belongs to the technical field of chemical regulation and control of plant flowering, and particularly relates to a flower increasing agent for increasing the flower quantity of pawpaw passion fruits, and a using method and application thereof.

Background

The pawpaw and passion fruit is also called as honey and passion fruit, and is named because the fruit is similar to papaya in shape and the flower is rich and pleasant in fragrance. The pawpaw passion fruit has strong climbing capability, is easy to shed, has good shading property, and can flower in the same year, and flowers are large, beautiful and beautiful. The main crown petals are thickened and flat, the outer side is emerald green and the inner side is purple and downward, the diameter of the crown can reach 10-15cm, and the lower part of the crown is covered with a bell; the secondary corolla petals are transformed into flesh with linear sagging, the purple and white colors are alternated, the surface is bright as if beads are strung into a curtain, and in addition, the central 5 elliptic yellow anthers and 3 light green stigma are added, so the ornamental value is realized. The flowering period of the whole plant of the papaya and passion fruit in south China can be more than half a year, and the papaya and passion fruit becomes a first-class plant resource for beautifying and enjoying the cool and ornamental flowers in modern gardens and courtyards in recent years. However, due to vigorous vegetative growth, the reproductive growth is limited by the luxuriant branches and leaves. The specific expression is that after the flowering phase is promoted, the flower buds of the common branches are differentiated to be few and have more vacant nodes, and some branches are crisp and become non-bud 'lazy vine', even part of the existing flower buds are premature senility and fall off after failing to bloom, so that no small loss is caused to the ornamental value of the branches. The technical report of increasing the flowering quantity of the pawpaw and passion fruit and improving the ornamental value of the pawpaw and passion fruit is not found so far.

THE ADVANTAGES OF THE PRESENT INVENTION

The invention relates to a flower increasing agent for increasing the flower quantity of pawpaw passion fruit and a using method thereof. The plant growth regulator is used for coordinating with necessary nutrient elements to regulate the balance of vegetative growth (branch and root and the like) and reproductive growth (flower, fruit and the like) of the pawpaw passion fruit, green leaves of green branches can be kept, the drop of young buds can be reduced, the number of the buds can be increased, a part of toroids can be induced to bud and bloom (the phenomenon of the extremely rare reversion in the natural world), so that the total amount of flowers is obviously increased, particularly, some toroids have to hang beautiful flowers in the air like green springs, the rare wonders of the world are formed, and the ornamental degree is greatly improved.

Detailed Description

The present invention is further explained below with reference to specific embodiments, it should be noted that the specific embodiments are not intended to limit the scope of the present invention.

Example 1: the invention relates to a preparation of a flower increasing agent for increasing the flower quantity of pawpaw passion fruit, which comprises the following steps:

the method comprises the following steps: preparing solution A, mixing Zeatin (Zeatin), Indoleacetic acid (indole acetic acid) and Sodium nitrophenolate (Sodium phenolate) to prepare aqueous solution, wherein the concentration of Zeatin is 1.0mg/L, the concentration of Indoleacetic acid is 150mg/L and the concentration of Sodium nitrophenolate is 2 multiplied by 10 ^-3 mg/L；

Step two: preparing solution B, mixing chelated zinc, boric acid and monopotassium phosphate to prepare an aqueous solution, wherein the concentration of the chelated zinc is 90mg/L, the concentration of the boric acid is 110mg/L, and the concentration of the monopotassium phosphate is 3000 mg/L;

step three: and (3) mixing the solution A and the solution B according to the volume ratio of 1: 1, mixing to obtain the flower increasing agent.

When the concentration of zeatin in the solution A is 0.5-2.0mg/L, the concentration of indoleacetic acid is 50-250mg/L, and the concentration of compound sodium nitrophenolate is 2 x 10 ^-3 -2×10 ^-4 In mg/L, the flowering number, the tendril bud number and the tendril flowering number of the pawpaw passion fruit are increased along with the increasing concentration of each component in the zeatin aqueous solution, the indoleacetic acid aqueous solution and the compound nitrophenol sodium aqueous solution, and in consideration of the cost, the specific embodiment only provides the preferable concentration of each component in the embodiment 1.

The use effect test of the use method of the flower-increasing agent prepared in the above example 1 was carried out:

the method comprises the following steps: dividing the implementation case into an area A and an area B; the area A is a treatment group, the treatment group is a flower increasing agent compounded by different nutrient elements and different plant growth regulators, the treatment group is divided into 9 groups, and each group is 5 plants; the clear water is taken as a control group in the area B and is singly taken as 1 group, the group is 5 plants, and the preparation of each group of the preparation in the area A and the area B is shown in the table 1:

step two: after the top of the main stem of the plant with the plant height of about 1.8 is removed, the preparations in the area A and the area B are respectively sprayed on branches and leaves; spraying again for the second time (the two times are separated by about 20 days) at the bud emergence initial stage of the branch and leaf shed, and counting the number of buds and flowers when the time is 30 days and 60 days from the day. The two-time spraying effect is shown in table 2:

table 2: use effect of papaya and passion fruit flower increasing agent (2020 and 2021 years)

As shown in Table 2, the flower-increasing agent of group (1) A-1, which contains the component of this example 1, has the best number of knots, curly beard and flowers, indicating that the flower-increasing agent of this example 1 has the best flower-increasing effect. (2) The compound fertilizer is sprayed twice in the first bud period after shed topping and shed forming of branches and leaves of the main stems of the plants, the flowering rate reaches 97.2 percent after 60 days, is 23.2 percent higher than that of a control group in a B area of 74.0 percent, and has obvious flower increasing effect. (3) It is noted that the percentage of tendrils among 392 buds after 60 days was up to 25% in 98, and the flowering rate of tendrils was almost 100%, while those of the control group in B were zero. Therefore, in the invention patent of the application, the differentiation formation of tendrils is an important factor for improving the appreciation of the pawpaw passion fruit by the flower increasing agent.
