Abstract
The invention discloses a kind of summer water management methods of substrate culture blueberry, in whole day different time sections, the blueberry of substrate culture is irrigated by different Irrigation Frequency and irrigation volume, to reach the temperature of control high temperature noon, matrix period, blueberry root system activity and water absorbing capacity are improved, blueberry blade is avoided to cause shrivelled because of physiological water shortage.
Description
Technical field
The invention belongs to field of plant growing technology, and in particular to a kind of summer water management side of substrate culture blueberry
Method.
Background technique
As market sharply increases blueberry demand, China's blueberry cultivated area increase it is swift and violent, from 24 in 2001
hm2Rise to more than 30,000 hm in 20152, total output is up to 4.5 ten thousand t.China has become Asia blueberry cultivated area maximum, the world
Country with fastest developing speed in range, production area account for 16% or more of the whole world.However, China's yield only accounts for the 4% of global yield, put down
Equal per mu yield is only the 1/3 of developed country.Unfavorable grown on soil blueberry is one of the main reason for average yield per mu is low.Such as
What makes blueberry high yield in the environment of being not suitable for, and is just becoming one of the main problem that blueberry scientific research faces.
Recently, it has been found that containerization substrate culture technology may be implemented in the fast fast-growing of blueberry under unfavorable soil environment
It is long, there is greatly utilization and promotion potential.Under greenhouse controllable environment, moreover it is possible to which the anti-season harvesting for meeting blueberry obtains high
Income.
However in production practices, even if the moisture content in matrix is very high, the blueberry blade of substrate culture is fine in summer
, easily there is physiological water deficit in it and blade tip or edge are shrivelled, and when serious, shrivelled burning leaf symptom occurs for whole strain blade.
In producing at this stage, the method that blueberry substrate culture uses timing irrigation, but this method easily leads to matrix oxygen content deficiency
Or substrate temperature fluctuation is larger, and then causes root growth bad or vigor reduces, and keeps its upward water supply capacity insufficient, blade from
And there is physiological water shortage symptom.Therefore, how to avoid blueberry blade from being damaged, be that the core of blueberry substrate culture management is asked
One of topic.
Summary of the invention
It is an object of the invention to：For the problem in blueberry substrate culture, to control matrix noon temperature as mesh
, by way of adjusting Irrigation Frequency, avoid blueberry root system since noon matrix growth environment is unfavorable for moisture absorption, and lead
Cause blueberry Leaf Physiology water shortage and it is shrivelled.
The present invention can be achieved through the following technical solutions：
Thermometer is placed in the middle part of blueberry cultivation matrix, monitors substrate temperature.
2 hours after the rise of the summer sun, start to irrigate, until irrigating 4 times when the morning 11, irrigation interval time is consistent, 4 times
Irrigation water inventory account for whole day irrigate water inventory 30%-35%, matrix discharge water account for whole day discharge water total volume 5%-10%.
30 divide in the morning 11 when afternoon 14, and control substrate temperature is lower than 30oC was irrigated once every 20-30 minutes, this
The irrigation water inventory of period accounts for the 40%-45% that whole day irrigates water inventory, and the water of matrix discharge accounts for whole day discharge water total volume
50%-60%。
When afternoon 14 30 divide to the setting sun before 2 hours, irrigate 3 times, irrigate interval time it is consistent, during which irrigate water inventory account for entirely
It irrigates the 20-30% of water inventory, and the water of matrix discharge accounts for the 30%-45% of whole day discharge water total volume.
Matrix whole day total displacement accounts for the 20%-30% of irrigation quantity.
By the utilization of the technical program, have the following advantages that compared with prior art：
On the basis of irrigation total Water is consistent, by increasing noon Irrigation Frequency, the method for controlling substrate temperature both be can guarantee
The moisture supply of whole day, while noon substrate temperature is reduced again, root activity is improved, the suction of high-temperature time section root system is promoted
It is shrivelled because of physiological water shortage to avoid blueberry blade for outlet capacity.
Detailed description of the invention
Fig. 1 is blueberry burning leaf amount newly-increased daily under different in moisture way to manage.
