Description
Technical Field
The invention relates to the technical field of tropical fruit tree cultivation, in particular to a novel mango flowering regulation and control method.
Background
Mango (Mangifera indica L.) is a plant of the genus Anacardiaceae (Anacardiaceae) and mango (Mangifera L.), has important economic and nutritional values, is widely planted in more than 100 countries of the world, and is the largest major production region of mango. At present, Tainong No. 1, Jinhuang, Guifei and the like are produced with main cultivated varieties, but the varieties have the problems of low temperature intolerance, overcast and rainy weather, easy no embryo fruit, poor appearance quality of the fruit, poor resistance and the like. The Hongnong No. 1 mango has the characteristics of strong low-temperature and overcast and rainy resistance, good appearance quality, strong resistance and wide adaptability. The variety is obtained by breeding excellent hybrid parents, is bred by cooperation of a south subtropical crop research institute of the Chinese tropical agricultural academy of sciences, Sharpleaf agriculture development Limited responsibility company in Panzhihua city and a gardening station in Huapan county in Yunnan province, is approved by the national examination committee of tropical crop varieties (approval serial number: hot quality approval 2014005) in 2014, and is planted in dry and hot valley areas of Yunnan, Guangxi, Guangdong and Sichuan. However, the production of the variety still has problems, mainly including that the flower bud differentiation requires relatively low temperature, more strict measures for controlling tips and promoting flowers are needed to be beneficial to improving the flowering rate of the tips, the content of soluble solids in fruits is low, and the taste is slightly light.
In production, the conventional tip-controlling and flower-promoting measures are a method combining soil application of paclobutrazol and foliage spraying of ethephon regulation and control. The major features of the mango flowering induction phase are the active changes in endogenous hormones, carbohydrates, slightly induced flowering genes and other flowering signals that ultimately cause the transformation of the apical meristem of the buds from vegetative to reproductive growth. And the paclobutrazol affects the carbohydrate and related enzyme activity, gibberellin, abscisic acid and cytokinin content in mango buds, and simultaneously has the ratio of C to N and psiwThe leaf water potential rises, thereby causing the early flowering phenomenon of the mango. Soil fertilizerAfter the paclobutrazol is used for a plurality of years, the flowering period of plants is always disordered, flowers are scattered but not concentrated, the vegetative growth of trees is also severely inhibited, and paclobutrazol is remained in the trees and fruits. The residual period of the paclobutrazol is long, and the problems of premature senility of tree vigor, shrinking branch tips, difficult flower forcing and the like are easily caused by excessive application or perennial application of the paclobutrazol.
Obviously, the soil application paclobutrazol does not meet the requirements of green environmental protection and sustainable development, and the safe and efficient mango flower formation medicament is very important. The mepiquat chloride has the chemical name of Dimethyl Piperidine Chloride (DPC) and is a quaternary ammonium salt growth retardant which is mild in property and nonirritant, and is a safe and efficient plant growth retardant widely reported to be used for controlling the vegetative growth of crops in recent years. In contrast to paclobutrazol, mepiquat chloride and uniconazole are highly effective, low-toxicity, low-residue and low-pollution plant growth retardants. At present, the mepiquat chloride and the uniconazole compound agent have no related report on mango flowering regulation.

To demonstrate the effect of the present invention, statistics were made on the planting conditions of the Hongnong No. 1 mangoes of examples 1 to 3 and comparative examples 1 to 8.
(1) Flower formation rate of mango
The statistical method comprises the following steps: before the flower formation regulation and control, the final tip hanging cards with consistent growth vigor and no diseases and pests are selected for each plant in different directions and different heights,
20 branches of each hanging card are used for counting the flowering rate of the branches. Flower formation rate = (number of flower-forming branch tips/total number of branch tips) 100%. The 4 trees are taken as a group, the repetition is carried out for 3 times, the average value is taken, and the statistical result is shown in a table 1:
TABLE 1 Hot agricultural No. 1 mango shoot flowering rate
| Sample (I) | Shoot flowering rate (%) |
| Example 1 | 88.0±10.8a |
| Example 2 | 93.7±4.0a |
| Example 3 | 92.0±1.7a |
| Comparative example 1 | 43.3±5.8c |
| Comparative example 2 | 40.0±5.0c |
| Comparative example 3 | 66.3±9.0b |
| Comparative example 4 | 60.0±18.0bc |
| Comparative example 5 | 53.0±10.4bc |
| Comparative example 6 | 98.3±1.5a |
| Comparative example 7 | 52.7±3.5c |
| Comparative example 8 | 95.3±5.0a |
Description of the invention: the same letters are marked after the same column of numerical values to indicate that the difference is not significant by SNK comparison.
As can be seen from table 1, the shoot flowering rate of examples 1 and 2 was not significantly different from that of comparative example 6 (conventional paclobutrazol over soil group), but was significantly higher than that of comparative example 7 (clear water control group). The flowering rate of the shoot of the example 3 is not significantly different from that of the comparative example 8 (conventional paclobutrazol). However, the flowering rate of the shoot in example 3 was significantly higher than that in comparative example 7 (clear water control).
It should be noted that, the appropriate concentration of mepiquat chloride 2g/L used in examples 1 and 3 is the preferred concentration obtained by optimizing and combining the previous different concentration gradients (0.5, 1, 2, 4, 6 g/L), the mepiquat chloride and uniconazole used in example 2 is the preferred mixture ratio obtained by optimizing the previous orthogonal design scheme, and then the data and effects obtained by further verifying the examples and comparative examples are the basis.
The mepiquat chloride in the embodiments 1 and 3 is mild in drug property and free of irritation, is a safe and efficient plant growth regulator, only needs to be sprayed on leaf surfaces without soil application, and is stable and efficient in flowering regulation and control effect. The control effect and stability of the mepiquat chloride and uniconazole in the proper concentration ratio in the example 2 are the second time. Through continuous three-year field monitoring, the flower formation regulation and control effect is efficient and stable. Therefore, the flower formation regulation measures in the embodiments 1 to 3 can replace the conventional tesserae paclobutrazol to be used for the flower formation regulation of the Carinona indica No. 1.
In addition, the growth conditions of mango trees can be visually seen in the attached drawings 1-7, and fig. 1 and fig. 2 are respectively a full-bloom stage flowering effect graph and an initial-bloom stage flowering effect after the flowering regulating and controlling method is adopted, and compared with the flowering effect of clear water contrast in fig. 7, the flowering rate can be obviously improved. And fig. 5 and 6 also show the effect diagrams of the last blade tip turning green but the top bud already sprouting in the production process of the invention, and compared with the effect diagrams of the last blade tip turning green but the top bud already sprouting in the prior art shown in fig. 3 and 4, the mango tree adopting the method of the invention can enter a mature state in advance, which is more beneficial to mango flower bud differentiation.
(2) Fruit quality of mango
The statistical method comprises the following steps: reference to fruit quality indicators was made to tropical fruit variety analysis guidelines (weichang bin, 2017, chinese agricultural press). Statistics of soluble solid, soluble total sugar and titratable acidity indexes are carried out on the fruits of the mango trees of examples 1-2 and comparative examples 6-7, 12 fruits are randomly selected in each group, repeated for 3 times, and an average value is obtained, wherein the results are shown in a table 2:
TABLE 2 fruit Main quality index
| Sample (I) | Soluble solid/% | Soluble total sugar/% | Titratable acidity/%) |
| Example 1 | 16.3±1.1a | 4.8±0.6a | 0.16±0.01b |
| Example 2 | 14.4±1.2b | 4.4±0.5ab | 0.12±0.02c |
| Comparative example 6 | 14.0±2.6b | 3.6±0.3c | 0.15±0.00b |
| Comparative example 7 | 12.5±1.1c | 3.3±0.4cd | 0.20±2.01a |
In the step of regulating and controlling flowering in example 1, after the plant growth regulator is sprayed, the soluble solid content of example 1 is 16.3%, which is significantly higher than that of comparative examples 6 and 7, and is increased by 16% compared with comparative example 6 (conventional soil application of paclobutrazol) and 30% compared with comparative example 7 (clear water control); example 2 was 2% higher than comparative example 6 (conventional soil applied paclobutrazol) and 15% higher than comparative example 7 (clear water control). Furthermore, the soluble total sugars of examples 1 and 2 were increased compared to comparative examples 6 and 7; the titratable acidity of example 2 is reduced compared with comparative examples 6 and 7, and the titratable acidity of example 1 is reduced compared with comparative example 7, and has no significant difference with comparative example 6.
Overall, the soluble solids and soluble total sugars of examples 1 and 2 increased, the titratable acidity decreased, and the fruit quality increased, compared to the conventional soil applied paclobutrazol and clear water controls.
