Problems solved by technology

[0004] However, the traditional method of calculating the water consumption of plastic-covered plants is to calculate the change in water consumption from the film-covered period to the end of the growing season. Due to the differences in rainfall and soil water infiltration before and after the degradation of the plastic film, the traditional method has large calculation errors and low accuracy. lower

Embodiment 1

[0051] see figure 1 , Figure 4-8 , a method for calculating the water consumption of plants covered with degradable plastic films, the method for calculating the water consumption of plants covered with degradable plastic films includes the following steps:

[0052] S1. Use the drying method to calculate the soil quality and water content of the plant soil on the day before the mulching, the degradation time of the degradable mulch film, and the end of the plant growth season; the end of the plant growth season refers to the time when the plants are harvested or harvested.

[0053] S2. Calculate the soil water storage in the first time period from the plant soil mulching to the degradable mulch degradation time point;

[0054] S3. count the irrigation amount and rainfall in the first time period;

[0055] S4. Calculate the soil water storage at the time point of degradation of the degradable plastic film and the second time period at the end of the plant growth season;

Embodiment 2

[0064] see figure 1 with figure 2 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to figure 2 , the method for confirming the degradation time point of the degradable plastic film includes the following steps:

[0065] S1. Between the soil of the film-covered plants, select a plurality of degradable plastic films of equal length film-covered sections;

[0066] S2. Use a transparent gauze to cover the upper end of the degradable mulch film of the selected mulch section;

[0067] S3. Observe the changes of the degradable plastic film in the area covered by the transparent gauze by visual inspection;

[0068] S4. When 40%-60% of the degradable plastic film in the area covered by the transparent gauze is degraded, it is the t...

Embodiment 3

[0070] see figure 1 with figure 2 , wherein the same or corresponding components as those in Embodiment 2 use the corresponding reference numerals as in Embodiment 2, and for the sake of simplicity, only the differences from Embodiment 2 are described below. The difference between this embodiment 3 and embodiment 2 is: please refer to figure 2 , in step S1 of the method for confirming the degradation time point of the degradable plastic film, the number of selected film sections is 2-5, and the selected length of the film sections is 0.8m-1.3m. Selecting multiple film sections is convenient for determining the degradable film on behalf of the entire film area, effectively improving the accuracy of determining the degradation time point of the degradable film, and selecting an appropriate length of film section is convenient for manual visual observation to determine the degradation of the degradable film Condition.

Abstract

The invention discloses a method for calculating the water consumption of a plant covered with a degradable mulching film, and belongs to the field of evaluation of water retention capacity of degradable mulching films. The method for calculating the water consumption of the plant covered with the degradable mulching film comprises the following steps: calculating soil mass water content by a drying method; calculating plant water consumption in time periods before and after the degradation time point of the degradable mulching film; calculating the soil water storage capacity; obtaining an irrigation volume and rainfall; and calculating the water consumption of the plant covered with the degradable mulching film. The water consumption of the plant covered with the degradable mulching filmis calculated in a summation mode, the error of overall calculation of the water consumption of the plant covered with the degradable mulching film is effectively reduced, and therefore the plant water consumption and the plant moisture production efficiency under the degradable mulching film covering condition can be calculated more accurately. Degradable mulching film material products suitablefor the plant can be screened out accordingly, and the suitable degradation time of the degradable mulching film under the high plant water production efficiency can be obtained through calculation and comparative analysis.

Description

technical field [0001] The invention relates to the field of water retention performance evaluation of degradable mulch films, and more specifically relates to a method for calculating water consumption of plants covered with degradable mulch films. Background technique [0002] The mulch film is the ground covering film, usually transparent or black PE film, and there are also green and silver films, which are used for agricultural ground covering. Mulching film can not only improve ground temperature, water retention, soil conservation, fertilizer conservation and fertilizer efficiency, but also has many functions such as weed control, pest control, drought and waterlogging resistance, salt suppression and seedling protection, improvement of light and heat conditions near the ground, and sanitation and cleaning of products. . Degradable mulch is a new type of degradable mulch. The principle of degradation is that degradable biomass is mixed into the plastic components, s...
