The invention can realize the simultaneous irrigation of a plurality of blueberries, and ensures that the blueberries grow identically; irrigation water leakage is reduced, and water resources are saved; irrigation time is controlled to control irrigation quantity, irrigation water is mainly concentrated at the bottom of a pot, and blueberry root systems can be promoted to grow downwards.
Description
Technical Field
The invention relates to the technical field of blueberry irrigation, in particular to an irrigation method for promoting growth of potted blueberry root systems.
Background
The blueberry fruit contains rich nutritional ingredients, has good nutrition and health care effects, and also has the functions of preventing cerebral nerve aging, strengthening heart, resisting cancer, softening blood vessels, enhancing human body immunity and the like, and is called as a king of berries. The blueberries have the characteristics of less root hairs, shallow rooting and the like, the root clusters are mainly distributed in shallow soil, and after the potted blueberries are transplanted, the growth and development of the tree body and the yield can be seriously influenced during drought due to the poor water absorption capacity of the root system. The potted blueberries are cultivated by adopting a matrix in the planting process, the matrix has poor water retention capacity, water is irrigated frequently in hot weather, and the traditional irrigation mode is from top to bottom, so that irrigation water flows too much and cannot be fully absorbed by soil, and serious waste of water resources is caused.
In conclusion, for potted blueberries, because the main roots are not obvious, the potted blueberries have no root hairs, have poor water absorption capacity and the like, research on an irrigation method for promoting the growth of the root systems of the potted blueberries has important theoretical and practical significance for improving the water absorption capacity of the root systems of the blueberries, promoting the high yield and high efficiency of the blueberries and saving water resources.
Disclosure of Invention
The invention aims to provide an irrigation method for promoting growth of potted blueberry root systems, which can ensure that blueberry root systems have strong water absorption capacity in the planting process by prolonging blueberry root systems, so that blueberries can grow normally.
In order to achieve the above purpose, the basic scheme of the invention is as follows: an irrigation method for promoting growth of potted blueberry root systems, comprising the following steps:
(1) Determining the maximum point of the water absorption capacity of the root system of the potted blueberry: the potted blueberry is placed in sunlight, and the soil which is exposed to the air above the potted blueberry is covered by the cover, so that the purpose of reducing the evaporation of soil moisture is to ensure that the soil moisture consumption is mostly caused by the water absorption of blueberry root systems. Along blueberry root system growth direction, place a soil humidity sensor in the basin every 5CM, after fully irrigating the blueberry, observe the soil humidity change of humidity sensor in different layers of soil, after a day, record each layer of soil humidity, through curve fitting, obtain the minimum point of soil humidity, the minimum point of soil humidity just is the biggest point of blueberry root system ability to absorb water.
(2) The potted blueberry is placed on a tide seedling bed, irrigation is carried out on the potted blueberry through a tide irrigation mode, the soil in the pot is continuously filled with water through capillary action of the soil, the potted blueberry is weighed at intervals, when the weight is unchanged, the blueberry is fully irrigated, and the time for fully irrigating the potted blueberry through the tide is recorded.
(3) By controlling the time of tidal irrigation, the irrigation quantity can be controlled, and the actual irrigation time is calculated by the following formula:
by controlling the time of tidal irrigation, water is transported from bottom to top through soil capillary action, and the maximum water absorption capacity of the blueberry root system is reached through irrigation each time, so that the blueberry root system is promoted to grow downwards.
The method has the beneficial effects that:
1. through the morning and evening tides, can realize that many basins of blueberries irrigate simultaneously, and the volume of irrigating is unanimous, has ensured that the blueberry growth vigor is the same.
2. Through tidal irrigation, irrigation water leakage is reduced, and water resources are saved.
3. Through tidal irrigation, irrigation time is controlled to control irrigation quantity, irrigation water is mainly concentrated at the bottom of a pot, and blueberry root systems can be promoted to grow downwards.
Drawings
FIG. 1 is a schematic diagram of a system according to the present invention.
Detailed Description
The invention will be further described with reference to the drawings and the specific embodiments, but the scope of the invention is not limited thereto.
Examples: an irrigation method for promoting growth of potted blueberry root system comprises the steps of firstly determining the maximum point of water absorption capacity of the potted blueberry root system: the potted blueberry is placed in sunlight, and the soil which is exposed to the air above the potted blueberry is covered by the cover, so that the purpose of reducing the evaporation of soil moisture is to ensure that the soil moisture consumption is mostly caused by the water absorption of blueberry root systems. Then, a soil humidity sensor is placed in the basin every 5CM along the growth direction of the blueberry root system, after the blueberry is fully irrigated, the numerical value of the soil humidity sensor reaches 35%, the soil humidity changes of the soil humidity sensors of different layers are observed, after one day, the soil humidity of each layer is recorded, the soil humidity at the position 5CM away from the ground is 34%, the soil humidity at the position 10CM away from the ground is 32%, the soil humidity at the position 15CM away from the ground is 30%, the soil humidity at the position 20CM away from the ground is 33%, and the lowest point of the soil humidity is near 13CM away from the ground and is the maximum point of the water absorption capacity of the blueberry root system through curve fitting. The potted blueberries are placed on a tide seedling bed, the potted blueberries are irrigated in a tide irrigation mode, the soil in the pot is continuously filled with water through capillary action of the soil, the potted blueberries are weighed at intervals, the weight of the potted blueberries is unchanged after 20 minutes, and the blueberries are irrigated fully. By controlling the time of tidal irrigation, the irrigation quantity can be controlled, and the actual irrigation time is calculated by the following formula:
the actual irrigation time is 11 minutes, water is transported from bottom to top through soil capillary action, irrigation is stopped after the water absorption capacity of the blueberry root system is maximum, and the blueberry root system is promoted to grow downwards.
The principles and embodiments of the present invention have been described in detail with reference to specific examples, which are provided to facilitate understanding of the method and core ideas of the present invention; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present invention, the present description should not be construed as limiting the present invention in view of the above.
