Example Embodiment

[0040] The following detailed description will be further described below with reference to the accompanying drawings and examples. It will be appreciated that the specific embodiments described herein are only used to explain the relevant invention, not the limitation of the invention. It will also be otherwise that only the portion related to the invention is shown in the drawings.

[0041] It should be noted that the features of the present application and the features in the embodiments in the present application can be combined with each other in the case of an unable conflict. The present application will be described in detail below with reference to the accompanying drawings.

[0042] Please refer to figure 1 A method of cultivating planting plants for the present application, including the following steps:

[0043] Get the original organic wastewater to detect the composition ingredients in the original organic wastewater, remember to i (i = 1 ... n); detecting the original organic wastewater a i Content P 1 (A i (i = 1 ... n);

[0044] Get rain, detecting A in the rain i Content P 2 (A i (i = 1 ... n);

[0045] Get the soil, plant plants on the soil; detect A i Content P 3 (A i (i = 1 ... n);

[0046] According to the type and growth stage of the plant, the plant obtains the composition corresponding to each of the components. i Tolerance limit P L (A i (i = 1 ... n);

[0047] The original organic wastewater is mixed with the rain water to obtain a watering liquid, watering the water soil, so that the water contained in the water is watered. i The content is equal to or equal to equal to the tolerance limit P L (A i(i = 1 ... n).

[0048] Specific, P 1 (A i The unit is kg / L, P 2 (A i The unit is kg / L, P L (A i ) And P 3 (A i Both are percentage.

[0049] Specifically, the watering fluid is based on P 1 (A i ), P 2 (A i ), P 3 (A i ) And tolerate limit P L (A i The mixing ratio of the original organic wastewater and the rain water is obtained so that the soil is contained in the soil after watering the soil after mixing water. i The content is equal to or equal to equal to the tolerance limit P L (A i (i = 1 ... n).

[0050] Specifically, the plant is constitrated in various constituents a i Tolerance limit P L (A i ) Is controlled by its species and growth stage, and different plants have corresponding components in different plants. i Tolerance limit P L (A i ) Is also different; for example, Table-1 is a tolerance limit for a partial plant in a seeding period for reference, where A 1 Nitrogen, A 2 Salt, A 3 Chromium.

[0051] P L (A i )

[0052] Table 1

[0053] Working principle: by detecting the composition ingredients of the original organic wastewater and each of the components contents 1 (A i ), Detecting A in rainwater i Content P 2 (A i ), Detecting A in soil i Content P 3 (A i ), At the same time, according to the type of plant and its growth stage, tolerance limits P, corresponding to each constituent component. L (A i ); Through P 1 (A i ), P 2 (A i ), P 3 (A i ), P L (A i The value, so that the mixing ratio of the original organic wastewater and the rain water can be quantified, and the soil A i The content is less than or equal to the tolerance limit P L (A i By the above method, the zero emissions of each substance in the original organic wastewater can also be achieved while the plant provides growth nutrients.

[0054] According to the method provided by the organic wastewater, the method of cultivating planting plants, on the one hand, some substances in organic waste water can provide nutrient resources for plants in the premise of the tolerance limits of plants, and turn waste into treasures; on the other hand Realize the zero emissions of each substance in organic wastewater, save costs.

[0088] The aqueous rate W of the soil is detected, for example, the value of W is 12%.

[0089] S502: Calculate each composition component a i Corresponding original organic wastewater - mixed ratio of rain i;

[0090]
