Description
Technical Field
The invention relates to a method for preventing grape branches from being drained, and belongs to the technical field of agricultural planting.
Background
Grapes are tree species with the largest planting area of deciduous fruit trees in the world, but in partial areas, cold and dry fruits in winter and spring, the phenomenon of grape branch trunk bleeding frequently occurs, root systems are bred again, the yield of the current year is influenced, and the yield of the second year or even the third year is influenced by re-culturing main vines.
The main reasons for the grape branches to be drained are two, firstly, the grapes are vines, and the branches are not as high in quality degree as other fruit trees, so that moisture is easily dissipated; on the other hand, because the freezing resistance of the root system is poor, the freezing injury happens when the soil temperature is minus 7 to minus 5 ℃, the root system loses the water absorption capacity after being frozen, so that the water can not be supplied to the overground part of branches in time, and the two parts together cause the occurrence of the pumping-out. Therefore, how to normally supply water to the root system and even supply water to the branches in advance and reduce the water evaporation of the branches is a main technical problem for preventing the branches from being dried. At present, the method of burying the branches with soil is generally adopted to prevent the branches from being drained, on one hand, the branches are still drained when the branches are too early unearthed, and the branches sprout in the soil when the branches are too late unearthed, so that the branches are put on shelves and the yield is influenced. On the other hand, the method consumes a large amount of labor, and a large amount of surface soil needs to be taken from the row space, so that the ecology is damaged. Therefore, a simple and economic method for preventing the grape branches from being drained is not available.

By taking the non-grafted self-rooted seedling of cabernet sauvignon as a control, the pumping rate of the self-rooted seedling of cabernet sauvignon in spring of 2021 is found to be more than 32%, and the pumping phenomenon does not occur by the treatment mode of the embodiment 1 of the invention.
Example 2
In a vineyard of Jiaodong where severe cabernet sauvignon draining occurred:
(1) planting an annual stock 'SA 15' seedling in a garden in 2019, and culturing to form a stock SA15 trunk;
(2) carrying out green branch grafting of cabernet sauvignon on the well-grown semi-lignified stock branch at the position 60cm high in 5/25/2020, vertically drawing and binding after scion sprouts, pinching after the scion grows to a terminal filament, and horizontally binding and fixing the scion to a first steel wire 60cm high by using a binding wire to form a single-stem single-arm inverted T shape;
(3) the scion branches are cultured into Cabernet Sauvignon grape vines, short tips are trimmed in winter, and the Cabernet Sauvignon grape vines are not laid on shelves;

(5) the water-absorbing cotton film-coated material is removed before the cabernet sauvignon grape sprouts, so that the cabernet sauvignon grape branches can be prevented from being drained.
The root system spring respiration initiation course of the stocks 'SA 15' and 'Cabernet Sauvignon (CS)' was determined using non-grafted 'Cabernet Sauvignon (CS)' as a control, and the results are shown in fig. 2, in which a is a graph comparing the fine root respiration rate and b is a graph comparing the capillary root respiration rate. As can be seen from FIG. 2, at lower temperature (2-6 deg.C), the respiratory rates of the rootstock 'SA 15' and the capillary root are higher than those of the root system of 'Cabernet Sauvignon (CS)' which indicates that the root system starts respiration at lower temperature in spring, and the respiration starts to supply energy to promote water absorption and supply to overground branches.
The effect of the 'SA 15' rootstock grafting on the occurrence of 'Cabernet Sauvignon (CS)' shoot current is shown in fig. 3, and it can be seen from fig. 3 that the 'SA 15' grafted cabernet sauvignon (CS/SA15) shoot current starts to rise significantly 2 months and 23 days, at which time the soil temperature at 10cm underground is 5.6 to 10.8 ℃, while the significant rise time of the control cabernet sauvignon CS from the root seedling stem current is 3 months and 19 days, at which time the soil temperature at 10cm underground is 9.1 to 12.7 ℃, and the peak time of stem current of cabernet sauvignon from the root seedling is 24 days later than that of the 'SA 15' grafted seedling.
The effect of the 'SA 15' grafting on the water content of the 'Cabernet Sauvignon (CS)' shoots by weighing the water content of the shoots and measuring the free and bound water contents using an abbe refractometer the results are shown in fig. 4, where a is the total water content, b is the free water content, and c is the bound water content. As can be seen from fig. 4, 'SA 15' reduced the total moisture content and free water content of the branches of 'Cabernet Sauvignon (CS)' and increased the bound water content compared to 'Cabernet Sauvignon (CS)' self-rooted shoots (12.22-2.2). Is beneficial to improving the cold resistance of branches during overwintering; as the ground temperature rises in spring, CS/SA15 begins to rise back after 2 months and 2 days, and the total water content and free water content of the branches begin to rise back after 3 months and 1 day. The time difference of the moisture rising time of the grafted seedling and the self-rooted seedling is about one month, so that the rootstock supplies moisture to the scion branch in advance and the occurrence of drying is avoided.
Comparative example 1
The only difference from example 1 was that the "annual rootstock SA 15" used in example 1 was replaced with "annual beda".
The spring survey in 2021 finds that the stem drawing rate of the berta grafted seedlings in the comparative example 1 is more than 30%, but the stem drawing phenomenon does not occur in the example 1 of the invention, which shows that the rootstock 'SA 15' used in the example 1 of the invention can absorb moisture in advance and supply the moisture to scion branches above the grafting opening, and the moisture of the branches can be supplemented in time.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
