Embodiment 1

[0027] Embodiment 1: when n=6, such as figure 1 As shown, the present invention comprises a flowmeter 2, and its one end is connected with irrigation pipeline 52 by solenoid valve 1; Flowmeter 2 is connected with solenoid valve 3,4,5,6,7,8 respectively by pipeline; Solenoid valve 3,4 . . 34,35 are connected with metering pump 41; Raw material tank 17 is connected with metering pump 41 and metering pump 42 respectively through filter 36; Raw material tank 19,20 is connected with metering pump 42 through filter 37,38 respectively; Metering pump 41 and mixing Bucket 43 is connected by pipeline, and filter 39 is installed in the middle thereof; Metering pump 42 is connected with mixing bucket 44 by pipeline, and filter 40 is installed in the middle thereof; Mixing bucket 43,44 is respectively connected with injection fertilizer machine 49 by electromagnetic valve; Fertilizer 49 is connected with irrigation pipeline 52 by one-way valve 50; This example is provided with a cover co...

Embodiment 2

[0041] Example 2: The method of the present invention was used to prepare and apply formula liquid fertilizer to tomatoes in the vegetative growth period in a solar greenhouse with a planting area of ​​660 m2.

[0042] According to experience, the requirement ratio of tomato to nitrogen (N), phosphorus (P2O5), potassium (K2O), calcium (CaO) and magnesium (MgO) in solar greenhouse is about 1.5:0.3:1.2:1.2:0.2.

[0043] The system formulates and applies the formula liquid fertilizer according to the above-mentioned fertilizer ratio. The preparation and application steps are as follows:

[0044] 1) Input the required fertilizer ratio into the programmable controller 51, and preset system operation instructions and programs;

[0045] 2) Put different kinds of basic water-soluble fertilizers into the raw material tank quantitatively according to their solubility, specifically put 200kg of nitrogen fertilizer into the raw material tank 15, put 200Kg of phosphate fertilizer into the ...

Description

technical field [0001] The invention relates to a formula liquid fertilizer preparation system and preparation method, which belongs to the technical field of agricultural water and fertilizer integration, and is especially suitable for the preparation of formula liquid fertilizer required by crops in agricultural parks. Background technique [0002] Due to its low production cost, high nutrient content, easy compounding, direct absorption by crops, convenient formula fertilization (balanced fertilization) and mechanized fertilization, liquid fertilizer has attracted more and more attention from various countries. [0003] Although some manufacturers adopt some chemical methods in the production of liquid fertilizers, they have not been popularized and used on a large scale due to the high transportation costs. And there is still a blank in the application of agricultural facilities. In order to facilitate the large-scale application of liquid fertilizer, reduce the cost of...
