Description
Technical field
The present invention relates to a kind of method for controlling potting soil moisture, belong to agrology technical field.
Background technology
At present, pot experiment be scientific worker pass through frequently with research method, water stress experiment be also crop adverse circumstance
How a kind of important content of research, control potting soil moisture, is a key link for carrying out water stress experiment,
Traditional method is carried out using the method for soil moisture content is determined, but intricate operation, and cost is high, all existing controls
Potting soil moisture method processed is still not perfect enough.
The content of the invention
The present invention goal of the invention be：A kind of method for controlling potting soil moisture is provided, using instrument is simple, cost
Low, method is reliable, using weight method, according to the weight of plant, potting soil moisture is controlled, to overcome the deficiencies in the prior art.
What the present invention was realized in：A kind of method for controlling potting soil moisture, the control potting soil moisture method
Carry out as follows：
Choose potted plant：Choose will using moderate water stress handle and observe paddy rice upgrowth situation and yield it is potted plant；
With moderate water stress, the method for its moisture control：
1）Total thinking of potting soil moisture control
Take the soil sample of upper, middle and lower part in basin to be dried after mixing every three days, determine its water content, such as soil moisture content is less than
The 85% of soil saturation water, then amount of makeup water to soil moisture content is the 95% of saturated soil water content；
2）Parameter is asked for：Potting soil air dry weight G1 is weighed, the water content W0 of potting soil is determined, potting soil saturation is determined
Water content W1, calculates oven-dried weight G2, the G2=G1/ (1+W0 of potting soil）, weigh sky basin weight G0；
The calculating of amount of makeup water：
A. after calculating amount of makeup water, the water weight in basin alms bowl；
B. before calculating amount of makeup water, the water weight in basin alms bowl；
C. calculating needs amount of water；
In the calculation procedure of amount of makeup water, water weight=G2 × W1 × 95% after the moisturizing in basin alms bowl, basin alms bowl before the moisturizing
In water weight=moisturizing before basin alms bowl gross weight-G0-G2-plant weight.
Water weight before the water weight-moisturizing needed after amount of water=moisturizing in basin alms bowl in basin alms bowl
= G2×W1×95% -（Basin alms bowl gross weight-G0-G2-plant weight before moisturizing）
Basin alms bowl gross weight before the+G0+G2 of=G2 × W1 × 95%+plant weight-moisturizing
=[G1/(1+W0）]×W1×95% + G0 +[G1/(1+W0）Basin alms bowl gross weight before the weight-moisturizing of]+plant.
The measure plant weight, using direct sampling method, in paddy rice breeding time, selects two basin plant, takes out and all plant
Strain, weighs its fresh weight, asks calculation per basin plant weight.
The water content W0 of the potting soil is determined to be carried out using oven drying method, and saturated soil water content W1 measure uses ring
The skill in using a kitchen knife in cookery.
The present invention uses weight method, according to soil wind desiceted soil weight, soil moisture content, saturated soil water content, empty basin alms bowl weight
And Plant weight, soil amount of water is calculated, so as to control potting soil moisture, present invention use instrument is simple, cost is low, side
Method is reliable, and it is convenient to be provided for crop anti-adversity research.
Embodiment
With reference to embodiment, the present invention is described in further detail, but not as limitation of the present invention.
What the present invention was realized in：
Embodiment 1：
Certain pot experiment, it is necessary to using the upgrowth situation and yield of moderate water stress processing observation paddy rice, illustrate in detail below
The step of controlling moisture:
（1）Parameter is asked for:Known potting soil air dry weight is 7 kg, and its water content is 4.05%, and its saturation moisture content is
48.18%, the oven-dried weight of potting soil is 6.728 kg, and empty basin weight is 0.406 kg.
（2）With moderate water stress（Control the 85-95% that potting soil water content is saturated soil water content）Exemplified by, say
The method of bright moisture control：
1. total thinking that moisture is controlled
Take the soil sample of upper, middle and lower part in basin to be dried after mixing every three days, determine its water content, such as soil moisture content is less than
The 85% of soil saturation water, then amount of makeup water to soil moisture content is the 95% of saturated soil water content.
2. the calculating of amount of makeup water.
A. after calculating moisturizing, the water weight in basin alms bowl.
The kg of water weight=6.728 × 48.18% × 95% after moisturizing in basin alms bowl=3.079
B. before calculating moisturizing, the water weight in basin alms bowl.
- 0.406-6.728-plant of basin alms bowl gross weight weight before water weight=moisturizing before moisturizing in basin alms bowl
C. calculating needs amount of water.
Need the water weight in basin alms bowl before the water weight-moisturizing after amount of water=moisturizing in basin alms bowl
= G2×W1×95% -（- 0.406-6.728-plant of basin alms bowl gross weight weight before moisturizing）
Basin alms bowl gross weight before=6.728 × 48.18% × 95%+0.406+6.728+ plant weight-moisturizings
Basin alms bowl gross weight before the weight-moisturizing of=10.213+plant
Key issue is to seek calculation plant weight, can use direct sampling method, in the paddy rice jointing stage, select two basin plant, take out complete
Portion plant, weighs its fresh weight, is 140 g, and it is 0.07 kg per basin plant weight to ask calculation.Then：
Need basin alms bowl gross weight before amount of water=10.213+plant weight-moisturizing
Basin alms bowl gross weight before=10.213+0.07- moisturizings
Basin alms bowl gross weight before=10.283-moisturizing
Embodiment 2：

48.18%, the oven-dried weight of potting soil is 6.728 kg, and empty basin weight is 0.406 kg.
（2）With severe water stress（Control the 65-75% that potting soil water content is saturated soil water content）Exemplified by, say
The method of bright moisture control：
1. total thinking that moisture is controlled
Take the soil sample of upper, middle and lower part in basin to be dried after mixing every three days, determine its water content, such as soil moisture content is less than
The 65% of soil saturation water, then amount of makeup water to soil moisture content is the 75% of saturated soil water content.
2. the calculating of amount of makeup water.
A. after calculating moisturizing, the water weight in basin alms bowl.
The kg of water weight=6.728 × 48.18% × 75% after moisturizing in basin alms bowl=2.431
B. before calculating moisturizing, the water weight in basin alms bowl.
- 0.406-6.728-plant of basin alms bowl gross weight weight before water weight=moisturizing before moisturizing in basin alms bowl
C. calculating needs amount of water.
Need the water weight in basin alms bowl before the water weight-moisturizing after amount of water=moisturizing in basin alms bowl
= G2×W1×75% -（- 0.406-6.728-plant of basin alms bowl gross weight weight before moisturizing）
Basin alms bowl gross weight before=6.728 × 48.18% × 75%+0.406+6.728+ plant weight-moisturizings
Basin alms bowl gross weight before the weight-moisturizing of=9.565+plant
Key issue is to seek calculation plant weight, can use direct sampling method, in the paddy rice jointing stage, select two basin plant, take out complete
