Example 1
Test site: shanxi Daning Longtai double-wound agriculture and forestry science and technology limited company greenhouse.
Test materials: the ornamental pineapple of the varieties of red-head, new red star, computer baby, dove Ni and the like has seedlings with the seedling age of more than 6 months, and is required to grow robustly and have no plant diseases and insect pests.
Preparing a 1% ethephon aqueous solution, wherein the aqueous solution is acidic, regulating the pH value of the aqueous solution to 5.8-6.2 by potassium carbonate, pouring the aqueous solution from the top of a plant, pouring 20ml of each plant, and repeating the treatment once every seven days; and fertilization was stopped 30 days before ethephon administration and 30 days after the last administration. Meanwhile, a paclobutrazol group and a 6-BA group are used as positive control groups, and a clear water group is used as a negative control group. For each treatment of 50 pots, the growth characteristics and tillering conditions of seedlings were recorded (see fig. 1-4), and the average number of 50 parent plant tillering seedlings was taken as the number of tillers of a single plant.
The effect of each treatment on tillering of ornamental pineapple is shown in Table 1.
TABLE 1
As can be seen from the results in table 1, treatment of ornamental pineapple with 1% ethephon has an exponential increase in tillering number compared to the negative control group and also has a significant increase effect compared to the positive control group.
Example 2
Investigation of the influence of different concentration of the medicament on the tillering of ornamental pineapple
Different varieties of ornamental pineapple are treated with different concentrations of ethephon respectively, 20ml of each plant is poured from the top of the plant, the treatment is repeated once every seven days, and fertilization is stopped 30 days before ethephon is applied 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 negative control group (0%). And (3) each treatment of 50 pots records the growth characteristics and tillering conditions of seedlings, and the average number of 50 parent plant tillering seedlings is taken as the single plant tillering number.
The effect of different reagent concentrations on flush red tillers is shown in Table 2, the effect on new red star tillers is shown in Table 3, the effect on digital baby tillers is shown in Table 4, and the effect on dovonie tillers is shown in Table 5.
TABLE 2 Effect of different reagent concentrations on flush Red tillering
TABLE 3 Effect of different reagent concentrations on New Red Star tillering
TABLE 4 influence of different reagent concentrations on computer baby tillering
TABLE 5 influence of different reagent concentrations on dovonie tillers
As can be seen from the results in tables 2-4, after 0.5% -2% of ethephon is applied to different ornamental pineapple varieties, compared with a negative control group, the number of tillering buds is obviously improved, when the ethephon concentration is 1%, the number of tillering buds is highest, the leaf length and the leaf width reach the maximum value, and the plant growth vigor is best; compared with the positive control group, the tillering effect and plant growth vigor of the positive control group also have obvious advantages.
Example 3
Observing the influence of stopping fertilization time before pesticide application on tillering of ornamental pineapple
Stopping fertilizing 15 days, 30 days and 45 days before the application, taking normal fertilizing before the application as a control, not fertilizing within 30 days after the application, and examining the tillering number of ornamental pineapple after 4-6 months. And (3) each treatment of 50 pots records the growth characteristics and tillering conditions of seedlings, and the average number of 50 parent plant tillering seedlings is taken as the single plant tillering number.
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 fertilization was stopped before the application of the fertilizer had a significant effect on tillering of ornamental pineapple. The fertilization is stopped 15-30 days before the application of the fertilizer, and the fertilizer has obvious difference compared with the normal fertilization, so that the fertilization stopping effect is optimal 30 days before the application of the fertilizer. The reason for this result is presumed to be that the unfavorable environmental stress of stopping fertilization is favorable to the nutritive growth of pineapple to reproductive growth, whereas normal fertilization is favorable to the nutritive growth of pineapple and unfavorable to tillering.
Example 4
Examining influence of recovery fertilization time after pesticide application on tillering of ornamental pineapple
Stopping fertilization 30 days before the application, and recovering fertilization 15 days, 30 days and 45 days after the application respectively, taking normal fertilization after the application as a control, and examining the tillering number of ornamental pineapple after 4-6 months. And (5) recording tillering conditions of seedlings by each treatment of 50 pots, and taking the average number of 50 parent plant tillering seedlings as the single plant tillering number.
The effect of each treatment on tillering of ornamental pineapple is shown in Table 7.
TABLE 7 influence of fertilization time on tillering after application of the drug
As can be seen from the results of Table 7, the recovery of fertilization time after application also had a significant effect on tillering of ornamental pineapple. The fertilization is recovered 15-30 days after the application of the fertilizer, and the fertilizer has obvious difference compared with the normal fertilization, so that the fertilization recovery effect is optimal 30 days after the application of the fertilizer, and the growth of tillered seedlings is unfavorable if the time is longer.
Example 5
Investigation of the influence of different kinds of reagents to regulate the pH value of ethephon on the tillering of ornamental pineapple
After 1% ethephon solution is prepared, respectively adjusting the pH value to 5.8-6.2 by potassium carbonate, sodium carbonate and sodium hydroxide, pouring from the top of the plant, repeating the treatment once again at seven intervals; and fertilization was stopped 30 days before ethephon administration and 30 days after the last administration. For each treatment of 50 pots, the tillering condition of seedlings is recorded, the average number of 50 parent plant tillers is taken as the tillering number of a single plant, and the result is shown in Table 8.
TABLE 8 Effect of different agents on adjusting ethephon pH on tillering
The ethephon is dissolved in water to form 1% aqueous solution, at this time, the aqueous solution is acidic, the PH is reduced to about 4, and the PH is adjusted to about 5.8-6.2 by alkaline reagent for application. Different alkaline agents can affect the tillering ability of the pineapple by the modulated agents. As is clear from the test results in Table 8, the effect of potassium carbonate was best although the tillering was promoted by the 3 alkaline agents after the adjustment.
Example 6
Observing the influence of the application times on the tillering of ornamental pineapple
Stopping fertilization 30 days before and 30 days after the application, examining the influence of different application times of 1% ethephon on the tillering number of ornamental pineapple, wherein each application time is 7 days, simultaneously taking clear water treatment as a control group, each treatment is carried out by 50 pots, recording the tillering condition of seedlings, and taking the average number of tillering seedlings of 50 parent plants as the tillering number of single plant. The results are shown in Table 9.
TABLE 9 Effect of the number of drug administrations on tiller number
As can be seen from the results of table 9, when the number of administrations was more than 1, the number of tillered seedlings was significantly different, and the number of treatments with the agent was determined 2 times on the basis of the same principle of saving effect.
Example 7
Investigation of influence of the applied part on tillering of ornamental pineapple
Stopping fertilizing 30 days before and 30 days after the application, treating different application positions (plant core and root system vicinity) twice by using 1% ethephon, and simultaneously taking clear water treatment as a control group to examine the influence of different application positions on the tillering number of ornamental pineapple, wherein each treatment is used for 50 pots, the tillering condition of seedlings is recorded, and the average number of 50 parent plant tillering seedlings is taken as the single plant tillering number. The results are shown in Table 10.
TABLE 10 Effect of application position on tiller number
Part of ornamental pineapple belongs to subfamily of ponding pineapple, and the name of ponding pineapple is from bowl-shaped space formed by leaves in the center of plant, which can accumulate rainwater, and is a growing point of the leaves and a flowering point of flowering. Because the blades are tightly surrounded, the water can be kept from losing for a long time. The center of the blade is provided with parenchyma cells, which are main parts for absorbing moisture and nutrition. As can be seen from the results in Table 10, the position of application has a greater effect on tillering number, and when applied to the core of the plant, the tillering effect is significantly higher than near the root system.
