Example 1
The test site comprises: shanxi Daning Longtai Shuangchuang agriculture and forestry science and technology Limited greenhouse.
Test materials: the ornamental pineapple of flush red, Xinhongxing, computer baby, doveni and other varieties has seedling age over 6 months and needs to grow robustly without diseases and insect pests.
Preparing a 1% ethephon solution, adjusting the pH value of the solution to 5.8-6.2 by using potassium carbonate, pouring 20ml of the solution from the top of each plant, pouring every two plants every seven days, and repeating the treatment once again; and fertilization was stopped 30 days before ethephon application and 30 days after the last application. Meanwhile, the paclobutrazol group and the 6-BA group are used as positive control groups, and the clear water group is used as a negative control group. The growth characteristics and tillering condition of each seedling are recorded after 50 pots of treatment (see attached figures 1-4), and the average number of tillering seedlings of 50 stock plants is taken as the number of tillers of a single plant.
The effect of each treatment on tillering of ornamental pineapples is shown in table 1.
TABLE 1
As can be seen from the results in table 1, when the ornamental pineapple is treated with 1% ethephon, the tillering number is exponentially increased compared with that of the negative control group, and the tillering number is significantly increased compared with that of the positive control group.
Example 2
Investigating the influence of different concentrations of medicaments on the tillering of ornamental pineapple
Different varieties of ornamental pineapples are respectively treated by ethephon with different concentrations, 20ml of ethephon is poured from the top of each plant, the treatment is repeated once every seven days, and the fertilization is stopped 30 days before ethephon application and 30 days after the last application. Meanwhile, the paclobutrazol group and the 6-BA group are used as positive control groups, and the clear water group is used as a negative control group (0%). And (3) treating 50 pots each, recording the growth characteristics and the tillering condition of the seedlings, and taking the average number of the tillered seedlings of 50 parent plants as the tillering number of a single plant.
The effect of different reagent concentrations on flush red tillering is shown in table 2, the effect on new red star tillering is shown in table 3, the effect on digital baby tillering is shown in table 4, and the effect on doveni tillering is shown in table 5.
TABLE 2 Effect of different reagent concentrations on red tillering
TABLE 3 Effect of different reagent concentrations on New Red Star tillering
TABLE 4 Effect of different reagent concentrations on tiller of computer baby
TABLE 5 Effect of different reagent concentrations on dove tillering
As can be seen from the results in tables 2 to 4, after 0.5 to 2 percent of ethephon is applied to different varieties of ornamental pineapples, the tillering bud number of the ornamental pineapples is remarkably improved compared with that of a negative control group, when the ethephon concentration is 1 percent, the tillering bud number is the highest, the leaf length and the leaf width also reach the maximum values, and the plant growth vigor is the best; compared with a positive control group, the tillering effect and the plant growth vigor of the plant have obvious advantages.
Example 3
Investigating the influence of the fertilization stop time before pesticide application on the tillering of ornamental pineapple
The fertilization is stopped 15, 30 and 45 days before the fertilization respectively, normal fertilization before the fertilization is taken as a control, no fertilization is carried out within 30 days after the fertilization, and the tillering number of the ornamental pineapple is inspected after 4-6 months. And (3) treating 50 pots each, recording the growth characteristics and the tillering condition of the seedlings, and taking the average number of the tillered seedlings of 50 parent plants as the tillering number of a single plant.
The effect of each treatment on tillering of ornamental pineapple is shown in table 6.
TABLE 6
As can be seen from the results in table 6, whether or not to stop fertilizing before application of the fertilizer significantly affects tillering of ornamental pineapples. The fertilization is stopped 15 to 30 days before the fertilization, and the fertilization is obviously different from the normal fertilization, so that the fertilization stopping effect is the best in 30 days before the fertilization. The reason for this is presumed to be that the unfavorable environmental stress of stopping fertilization favors the vegetative growth of pineapple turning to reproductive growth, while normal fertilization favors vegetative growth of pineapple and is unfavorable for tillering.
Example 4
Investigating the influence of the fertilizer application time after the pesticide application on the tillering of the ornamental pineapple
The fertilization was stopped 30 days before the application of the pesticide, and resumed 15, 30 and 45 days after the application of the pesticide, and the tillering number of ornamental pineapple was examined 4 to 6 months later, with the normal fertilization after the application as a control. And (4) treating 50 pots each, recording the tillering condition of the seedlings, and taking the average number of the tillering seedlings of 50 parent plants as the tillering number of a single plant.
The effect of each treatment on tillering of ornamental pineapples is shown in table 7.
TABLE 7 Effect of fertilization time on tillering after application of the drug
As can be seen from the results in table 7, the restoration of fertilization time after application of the drug also had a significant effect on the tillering of ornamental pineapples. The fertilizer application is recovered 15-30 days after the application of the fertilizer, and the fertilizer application has obvious difference compared with the normal fertilizer application, so that the fertilizer application recovery effect is optimal 30 days after the application of the fertilizer, and the growth of tillering seedlings is not favorable if the fertilizer application recovery time is longer.
Example 5
Investigating the influence of different reagents on the regulation of the pH value of ethephon on the tillering of ornamental pineapples
After a 1% ethephon solution is prepared, regulating the pH value of the mixture to 5.8-6.2 by using potassium carbonate, sodium carbonate and sodium hydroxide respectively, irrigating from the top of a plant, repeating the treatment once every seven days; and fertilization was stopped 30 days before ethephon application and 30 days after the last application. The tillering condition of each seedling is recorded after 50 pots of treatment, the average number of the tillering seedlings of 50 stock plants is taken as the tillering number of each plant, and the result is shown in a table 8.
TABLE 8 Effect of different Agents on tiller pH Regulation
Ethephon is dissolved in water to form a 1% aqueous solution, and the aqueous solution is in an acidic reaction, the pH is reduced to about 4, and the pH needs to be adjusted to about 5.8-6.2 by an alkaline reagent for application. Different alkaline agents can affect the tillering capacity of the pineapple. As seen from the test results in Table 8, the effect of potassium carbonate was the best, although the tillering was promoted by the 3 types of alkaline agents.
Example 6
Investigating the influence of the pesticide application times on the tillering of the ornamental pineapple
The fertilization is stopped 30 days before and 30 days after the fertilization, the influence of different application times of 1 percent ethephon on the tillering number of the ornamental pineapple is examined, the fertilization is carried out at the interval of 7 days every time, meanwhile, the clear water treatment is used as a control group, each 50 pots are treated, the tillering condition of seedlings is recorded, and the average number of 50 parent plant tillering seedlings is taken as the single tillering number. The results are shown in Table 9.
TABLE 9 Effect of application frequency on tiller number
As can be seen from the results in Table 9, when the application times are more than 1, the tillering number has a significant difference, and the treatment times of the medicament are determined to be 2 times according to the principle of saving the same effect.
Example 7
Investigating the influence of the drug application part on the tillering of the ornamental pineapple
The fertilization is stopped 30 days before and 30 days after the fertilization, different application parts (the center part of a plant and the vicinity of a root system) are treated twice by 1 percent ethephon, meanwhile, the influence of the different application parts on the tillering number of the ornamental pineapple is examined by using clear water as a control group, the tillering condition of seedlings is recorded after each treatment of 50 pots, and the average number of the tillering seedlings of 50 parent plants is taken as the tillering number of a single plant. The results are shown in Table 10.
TABLE 10 Effect of application location on tiller number
Part of ornamental pineapple belongs to the subfamily of ponding pineapple, and the name of ponding pineapple is that rainwater can be accumulated in a bowl-shaped space which is naturally formed by leaves in the center of a plant, and the space is a growing point of the leaves and a flowering point. Because the blade surrounds closely, can keep moisture can not run off for a long time. The leaf core has parenchyma cells, which are the main sites for absorbing water and nutrients. As can be seen from the results in Table 10, the application position has a large influence on the tillering number, and when the application is carried out on the center of the plant, the tillering effect is significantly higher than that near the root system.
