Detailed Description
The following examples are further illustrative of the present invention and are not intended to be limiting thereof.
Example 1 Effect of gibberellin solutions of different concentrations on Pycnopsis coccinea
Test site: glass greenhouse of Guangzhou flower research center slave base. The test site is located in the northeast of Guangzhou city in Guangdong province, has geographic coordinates of 113 degrees 17 '-114 degrees 04' at the east and 23 degrees 22 '-23 degrees 56' at the north, and belongs to subtropical monsoon climate with mild climate and abundant rainfall. The average annual air temperature is 21.6 ℃, the annual rainfall is 1892.2 mm, and the annual sunshine duration is 1588.9 hours.
Test materials: 300 crimson corn bulbs with consistent growth are purchased from Guangzhou Zhengxin gardening GmbH at 11/12/2020, and the average sphere diameter is 53.3 mm. After purchasing the coccyx peruvii seed ball, 1 g of aolv long-acting slow release fertilizer (15-9-12+2MgO + TE) is added to the basal part (namely the surface of the pot soil) of the coccyx peruvii seed ball to ensure sufficient nutrient supply. The gibberellins used were purchased from Biotechnology engineering (Shanghai) GmbH.
The test method comprises the following steps: 4 gibberellin solution treatments (T1, T2, T3, T4) at different concentrations of 100, 200, 400, 800mg/L were set and treated with clear water (CK) as a control. Three replicates were set with 20 balls per treatment. The preparation method of the gibberellin solution comprises the following steps: weighing the required dosage, placing the dosage into a beaker, dissolving and stirring the dosage evenly by using a small amount of absolute ethyl alcohol, and diluting the dosage to the required concentration by adding water.
The diluted gibberellin solution is atomized by a sprayer (machine) and uniformly sprayed on the crinopsis coccinella seed balls, and the spraying is carried out strictly in each treatment room according to the standard that the seed balls are completely wetted and do not drip. The spraying time of the second time is 7 days away from the first time, and the spraying time of the third time is 14 days away from the first time, wherein the spraying time of the second time is 3 times. The gibberellin solution is sprayed each time, the low-temperature or high-temperature weather is avoided, and the gibberellin solution is half finished at 9 to 9 am of the day.
The spraying time of the specific regulator in this embodiment:
spraying for the 1 st time: 1, month and 8 days 2021;
and (3) spraying for the 2 nd time: 1 month 15 days 2021;
and (3) spraying: 29 months 1 in 2021;
and (3) observing characters: when the regulator is sprayed for the 1 st time, the diameter of the coccinella coccinea seed ball is measured for the first time; after the regulator is sprayed for the 3 rd time, performing conventional cultivation management, wherein the specific management method comprises the following steps: the illumination is controlled to be 12000-25000 Lux; controlling the daily temperature to be 25-28 ℃ and the night temperature to be 13-20 ℃; the relative humidity is controlled to be 40-60 percent; adopting water and fertilizer integrated management, wherein the EC value of a fertilizer solution is 1.0-1.2 ms/cm, irrigating and applying water and fertilizer for 1 time in about 10-14 days, completely watering, and sufficiently watering; when the temperature is lower, the water supply is reduced, and the cold resisting capability is enhanced. The results of the effects of gibberellin solutions of different concentrations on the parfly jade after two months of regular cultivation and management are shown in fig. 1, 2, 3, 4, and 5. Performing last measurement on the diameter of the coccyx coccinellioides ball, and calculating the increment of the ball diameter by taking millimeters as a unit; and the number (unit/piece), length (unit/mm) and mass (unit/mg) of the thorn contained in each thorn seat are measured. Data were analyzed for variance using SPSS 21.0 software, and multiple comparisons were performed using Ducan's method.
TABLE 1 measurement of various physical Properties of red flower jade
Note: the difference of the lower case letters after the same column data shows that the difference is obvious (P < 0.05)
As can be seen from Table 1, the diameters of the coccyx treated before spraying the regulator were concentrated between 53.79 and 55.03mm, and there was no significant difference, indicating that the coccyx were uniformly sized and met the requirements of the test material selection.
The coccinella crenulata jade is sprayed with 200mg/L gibberellin solution (treated T2), the increment of the sphere diameter (6.74mm) is the largest, and then the increment difference of the sphere diameter reaches a significant level by 100mg/L gibberellin solution (treated T1), 400mg/L gibberellin solution (treated T3), 800mg/L gibberellin solution (treated T4) and clear water control.
The crocodile jades are sprayed with 800mg/L gibberellin solution (treated T4), each spiny seat has the largest amount of thorns (7.3), and then 400mg/L gibberellin solution (treated T3), 200mg/L gibberellin solution (treated T2), 100mg/L gibberellin solution (treated T1) and clear water are used for comparison, and except for 100mg/L gibberellin solution (treated T1), the difference of the thorns contained in the spiny seats reaches a significant level.
The coccinella crenulata jade is sprayed with 100mg/L gibberellin solution (treated by T1), the puncture length is the longest (24.16mm), and the puncture length difference reaches a significant level by 200mg/L gibberellin solution (treated by T2), 400mg/L gibberellin solution (treated by T3), 800mg/L gibberellin solution (treated by T4) and clear water control.
The daucus coccineus jadeite is sprayed by 100mg/L gibberellin solution (treated by T1), the quality of the spiny seat (37.4mg) is the largest, and the quality difference of the spiny seat reaches a significant level by 200mg/L gibberellin solution (treated by T2), 400mg/L gibberellin solution (treated by T3), 800mg/L gibberellin solution (treated by T4) and clear water contrast.
In conclusion, the regulator can be sprayed on the coccyx rubiginis seedball according to different requirements, and 200mg/L gibberellin solution is adopted for spraying to ensure that the diameter of the coccyx rubiginis seedball is increased most obviously; the quantity of the lunge contained in the crocus coccineus base is obviously increased by adopting 800mg/L gibberellin solution for spraying; spraying gibberellin solution of 100mg/L to increase the growth of the red corn; the quality of the crimson corn jade acanthus is obviously improved by spraying 100mg/L gibberellin solution; the gibberellin solution of 200mg/L is sprayed to rapidly increase the cocculus diameter, increase the number of thorns in the acanthopanax spinosus, increase the length of thorns and increase the quality of the acanthopanax spinosus.
It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the principles of the invention, and it is intended that such changes and modifications also fall within the scope of the appended claims.
