Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
This example was developed by eastern wind farm administration and Kunming school in Maitreya, Yunnan province in 2019 to 2021.
A high-yield high-quality high-yield method for promoting the differentiation of long-ear mulberry buds comprises the following steps:
1. planting and pruning
The planting density of the long-ear mulberry in the greenhouse is 1.5m multiplied by 2.0m, and the trunk of the 2-year-old long-ear mulberry plant is cut off at a position 1m away from the ground, so that the young shoots are sprouted. 5-6 shoots after sprouting are selected and left for growing, and the rest shoots are all erased. And (4) at the beginning of 1 month in winter, cutting the young shoots at a position which is about 20cm away from the trunk after the selected young shoots grow to the lignification of the base parts.
2. Spraying curcumin and fluazinone on branches
As can be seen from Table 1, the axillary bud germination time, axillary bud flowering rate, and the number of panicles per axillary bud of Morus lanigera were all advanced compared to the control after treatment with curcumin and fluazinone. The axillary bud germination time is 10mmol/L curcumin +4mmol/L fluazinone treatment which is the most ahead of the days of the control, is advanced by 10.28 days and is obviously earlier than other treatments; and the axillary buds treated by 5mmol/L curcumin have the shortest time of germination in advance and only germinate 3.52 days in advance compared with the control. Compared with the control, the axillary bud flowering rate of the 10mmol/L curcumin plus 4mmol/L fluazinone treatment is obviously higher than that of other treatments, and is increased by 19.01% compared with the control; the axillary bud flowering rate of the 2mmol/L fluazinone treatment is obviously lower than that of other treatments except the control, and is only improved by 3.04 percent compared with the control. Compared with a control, after the treatment of 10mmol/L curcumin, 4mmol/L fluazinone and 10mmol/L curcumin, the number of spica of each axillary bud is obviously higher than that of the control, and is respectively increased by 10.57 percent and 9.81 percent compared with the control; while none of the other treatments differed from the control to a significant level of difference.
TABLE 1 Effect of shoot spraying curcumin and fluopyridone on panicle formation in the first season of Morus elongata
Note: the data in the table are the average values of 3 repeated experiments, and different letters after the same column of numbers indicate that the difference is significant (P is less than 0.05) through Duncan new range detection, and the table is as follows.
3. Shading of light
The purpose of shading is to promote the flower bud differentiation and the formation of the flower spike of the Morus longissima. In late 12 months, the selected young shoots are cut off at a distance of about 20cm from the trunk, and then shaded to promote the flower bud differentiation and the formation of flower spikes. The shading method can cover the whole tree crown by using a shading net and can also shade light by using a shading system of the greenhouse. The germination of the mulberry buds growing at the beginning of 2 months begins. The effect of different shade degrees on spikelet formation in Morus longissima is shown in Table 2 below. As can be seen from Table 2, the light-shielding treatment can significantly promote the axillary bud flowering rate of Morus longissima, wherein the effect is best with a light-shielding rate of 65%; in addition, the light-shielding treatment also increased the number of ears in axillary buds, with the best effects of 65% and 75% light-shielding rate.
TABLE 2 influence of different shading degrees on the formation of first season spica of Morus longissima
4. Trunk girdling
The trunk callus of the long-spike mulberry grows slowly and cannot be peeled for a complete circle in girdling, otherwise, the tree vigor grows gradually weaker, the yield and the quality of the mulberry are affected by mild mulberry, and the plant is dead by severe mulberry. Therefore, only half girdling can be carried out on the trunk during girdling, the width of the half girdling is about 5mm, and the range is 2/3-3/4 of the trunk circumference. As can be seen from Table 3, after the trunk is half-girdled, the fruit setting rate, the soluble solid content of the fruit, the anthocyanin content and the titratable acid content of the Morus longissima are all obviously greater than those of the control; the fruit length, the single fruit weight and the solid acid ratio are also higher than those of the control, but the difference significance level is not reached.
TABLE 3 influence of trunk girdling on the fruit setting rate and fruit quality of Morus longissima
5. Application of dicyandiamide to roots
In 1-month-last ten days after shading, 19% of N and 7% of P are applied to each mulberry2O514% of K2And (3) applying 200g of urea and 50g of potassium sulfate to each strain of the mulberries subjected to the withering treatment after the compound fertilizer of O and the dicyandiamide subjected to different treatments in the table 4. As can be seen from Table 4, after dicyandiamide is applied, the utilization rate of the long-ear mulberry nitrogen fertilizer and the yield per mu are greatly improved; wherein the effect is best when 100g of the fertilizer is applied to each plant, so that 13.44kg of pure nitrogen is saved per mu every year, and the yield is increased by 17.30% per mu.
TABLE 4 influence of dicyandiamide application to the root of the longicorn mulberry nitrogen fertilizer utilization and yield
In conclusion, as can be seen from tables 1 to 5, the effect of the 10mmol/L curcumin +4mmol/L fluazinone treatment on the time for advancing the germination of axillary buds of Morus lancifolia is the best, and the effect on the rate of formation of the axillary buds of Morus lancifolia and the number of the flower ears of each axillary bud are also the best; the 3-needle shading net is used for shading 65 percent of the axillary buds of the Morus longissima and has the best effect on the flower forming rate of the axillary buds and the number of the flower spikes of each axillary bud; fruit quality indexes such as fruit setting rate, fruit length, single fruit weight, soluble solid content, anthocyanin content, titratable acid content, solid-acid ratio and the like of the mulberries can be effectively improved through semi-ring stripping treatment of the main stems; the application of 100g of dicyandiamide to the roots of each plant can obviously improve the nitrogen fertilizer utilization rate and acre yield of the longicornus mulberry and reduce the nitrogen fertilizer application amount. As can be seen from Table 1, by combining the above treatments, namely simultaneously using 10mmol/L curcumin, 4mmol/L fluazinone, 3-needle shading net, semi-girdling of trunk and 100g dicyandiamide treatment, the scion mulberry can simultaneously achieve the purposes of early axillary bud germination time, high axillary bud flowering rate, more flower ears of each axillary bud, high fruit setting rate, once fruit grows and aggravates, the content of soluble solids is improved, the content of anthocyanin is improved, the content of titratable acid is improved, the utilization rate of nitrogen fertilizer is improved, the yield per mu is improved, the yield is increased remarkably, and the usage amount of nitrogen fertilizer is reduced. Therefore, the method is an effective method for promoting the division of the florida longicornica buds and improving the yield and the quality.
