Description
Technical field
The present invention relates to a kind of irrigation method for improving water utilization rate.
Background technology
With expanding economy, agricultural water is increasingly in short supply.And at present when irrigating soil, also using very low
The original mode of level, i.e., by micro-judgment soil whether water shortage, then by virtue of experience irrigated again.This certainly will be caused to water
The waste of resource, influences the utilization ratio to water resource, increases the cost of agricultural planting.
The content of the invention
For above-mentioned technical problem, the present invention has designed and developed a kind of raising water money that can improve water resource utilization efficiency
The irrigation method of source utilization rate.
The technical scheme that the present invention is provided is：
A kind of irrigation method for improving water utilization rate, comprises the following steps：
Step 1: using continuous 10~15 days as one test period in a season, being poured at the 1st day to target plot
Water, and using the irrigation amount of the 1st day as standard irrigation amount, the every morning 9-10 points measurement target plot within the test period
Soil moisture value；Wherein, the target plot is the plot in vinyl house, is controlled within the test period in vinyl house
Temperature and illumination condition keep it is constant；
Step 2: soil moisture curve is drawn using the soil moisture value in test period, so as to obtain soil moisture
Changing rule, and find soil moisture and be declined to become between 50% timing node of the soil moisture value of the 1st day and the 1st day
Number of days interval；
Step 3: in the season, every the number of days interval, watered once to target plot, and irrigation amount every time
It is consistent with the standard irrigation amount.
Preferably, in the irrigation method of described raising water utilization rate, in the step one, with a season
Continuous 10~15 days as a test period, watered at the 1st day to target plot, and using the irrigation amount of the 1st day as
Standard irrigation amount, 9 points of every morning measures the soil moisture value in target plot within the test period.
Preferably, in the irrigation method of described raising water utilization rate, in the step one, Step 1: with one
Being watered as a test period at the 1st day to target plot for continuous 10 days in individual season, and with the irrigation amount of the 1st day
As standard irrigation amount, 9 points of every morning measures the soil moisture value in target plot within the test period.
Preferably, in the irrigation method of described raising water utilization rate, in the step 2, when number of days at intervals of
At 2 days, then cancel current test period, restart a test period, and in next test period, by standard
Irrigation amount rises to 1.5~2 times of a test period；The process repeatedly, until resulting number of days interval is more than or equal to 5
My god, then carry out the step 3.
Preferably, in the irrigation method of described raising water utilization rate, in the step 2, when number of days at intervals of
At 2 days, then cancel current test period, restart a test period, and in next test period, by standard

The step 3 is carried out again.
The irrigation method of the present invention for improving water utilization rate to target plot with regimen condition by being supervised
Survey, really go out optimal water opportunity and irrigation amount, and then realize and targetedly irrigate, both met being needed with water for soil
Ask, the utilization ratio to water resource is improved again, it is to avoid waste.
Embodiment
The present invention is described in further detail below, with make those skilled in the art with reference to specification word being capable of evidence
To implement.
The present invention provides a kind of irrigation method for improving water utilization rate, comprises the following steps：
Step 1: using continuous 10~15 days as one test period in a season, being poured at the 1st day to target plot
Water, and using the irrigation amount of the 1st day as standard irrigation amount, the every morning 9-10 points measurement target plot within the test period
Soil moisture value；Wherein, the target plot is the plot in vinyl house, is controlled within the test period in vinyl house
Temperature and illumination condition keep it is constant；
Step 2: soil moisture curve is drawn using the soil moisture value in test period, so as to obtain soil moisture
Changing rule, and find soil moisture and be declined to become between 50% timing node of the soil moisture value of the 1st day and the 1st day
Number of days interval；
Step 3: in the season, every the number of days interval, watered once to target plot, and irrigation amount every time
It is consistent with the standard irrigation amount.
The present invention first devises a test period, and the use regimen condition in goal in research plot is (i.e. native within the test period
Earth humidity situation of change), and it is showed with soil moisture curve；Soil moisture is found afterwards to drop to the 1st day
50% timing node, namely judge in which day, soil moisture drops to the 50% of the 1st day；This day is calculated to compare
Number of days interval between the 1st day；Just periodically watered afterwards using the number of days interval as standard to target plot, and still protect
Hold the irrigation amount relatively uniform with standard irrigation amount.
In order to ensure the accuracy of above-mentioned judgement, target plot can be designed smaller, such as designed target plot
Into the square plot that area is a square meter.
The irrigation method of the present invention for improving water utilization rate to target plot with regimen condition by being supervised
Survey, really go out optimal water opportunity and irrigation amount, and then realize and targetedly irrigate, both met being needed with water for soil
Ask, the utilization ratio to water resource is improved again, it is to avoid waste.
Accurately controlled to realize, improve the precision to water resource assignment, target plot of the invention is arranged on plastics
In greenhouse, and temperature and illumination condition in vinyl house is controlled to keep constant.
Preferably, in the irrigation method of described raising water utilization rate, in the step one, with a season
Continuous 10~15 days as a test period, watered at the 1st day to target plot, and using the irrigation amount of the 1st day as
Standard irrigation amount, 9 points of every morning measures the soil moisture value in target plot within the test period.
In order to reduce interference of the other factors to measurement result, time of measuring is set as at 9 points of every morning.
Preferably, in the irrigation method of described raising water utilization rate, in the step one, Step 1: with one
Being watered as a test period at the 1st day to target plot for continuous 10 days in individual season, and with the irrigation amount of the 1st day
As standard irrigation amount, 9 points of every morning measures the soil moisture value in target plot within the test period.
In order to reduce interference of the other factors to measurement result, it will design test period to 10 days.And the test period
Season will not be crossed over, but in the metastable the same quarter of weather condition.
Preferably, in the irrigation method of described raising water utilization rate, in the step 2, when number of days at intervals of
At 2 days, then cancel current test period, restart a test period, and in next test period, by standard
Irrigation amount rises to 1.5~2 times of a test period；The process repeatedly, until resulting number of days interval is more than or equal to 5
My god, then carry out the step 3.
The irrigation amount of the 1st day is set by experience.When performing a test, it is found that the irrigation amount of the 1st day is very few, cause
50% of the humidity of soil less than the 1st day, then will restart a new test period, and improve next survey after 2 days
The standard irrigation amount in examination cycle.
Preferably, in the irrigation method of described raising water utilization rate, in the step 2, when number of days at intervals of
At 2 days, then cancel current test period, restart a test period, and in next test period, by standard
Irrigation amount rises to 1.5 times of a test period；The process repeatedly, until resulting number of days interval is more than or equal to 5 days,
The step 3 is carried out again.
