Example Embodiment

[0037] A preferred embodiment of the present invention:

[0038] For the nutrient solution for solving calcium deficiency in solanaceous crops in fruiting period, the specific steps of the extraction configuration are as follows:

[0039] reference figure 1 ,

[0040] (1) First fermentation: feed 50% of raw material pig manure, 30% chicken manure, and 20% human manure from the inlet 1-1 of the first anaerobic fermentation tank 1 into the first anaerobic fermentation tank 1 according to the proportion. Anaerobic fermentation at room temperature, time: 15 days,

[0041] (2) Two-stage fermentation: the biogas slurry after the first fermentation is discharged into the second-stage anaerobic fermentation tank 2 for anaerobic fermentation at room temperature again for 20 days.

[0042] (3) Filtration and sedimentation: the decomposed biogas slurry produced after the secondary fermentation is filtered by the 20-mesh filter 3 and then discharged into the sedimentation tank 4 for precipitation....

Abstract

The invention discloses a nutrient solution used for avoiding calcium deficiency of solanaceous crops at fruiting period, and an application method thereof. The nutrient solution is prepared by taking biogas slurry as a basic raw material, and adding a corresponding amount of calcium superphosphate for digestion, wherein weight ratio of the biogas slurry to calcium superphosphate is 40:0.05-0.15; the biogas slurry is obtained via two-stage biogas digester normal temperature anaerobic fermentation by taking 45 to 55% of pig manure, 30 to 35% of chicken manure, and 15 to 25% of human manure as raw materials; the nutrient solution is obtained by taking the biogas slurry as the basic raw material and via scientific adding of corresponding nutritional ingredients; ammoniated superphosphate is prepared from composite organic ingredients; production cost is low; environmental protection performance is excellent; completeness and balance of biogas slurry fermentation are ensured by two-stage fermentation; diseases and insect pests are inhibited effectively; calcium deficiency of solanaceous crops at fruiting period is avoided; yield and commodity rate of solanaceous crops are increased greatly; and output value is increased.

Description

technical field [0001] The invention relates to a nutrient solution prepared by biogas slurry extraction, in particular to a nutrient solution for solving calcium deficiency in the fruiting stage of solanaceous crops and an application method thereof. Background technique [0002] Biogas slurry is rich in nitrogen, phosphorus, potassium, various amino acids, vitamins, proteins, gibberellins, auxins, sugars, nucleic acids, and antibiotics, as well as active resistant substances such as butyric acid, indole acetic acid, and vitamin B12 . Therefore, it has the double function of promoting crop growth and controlling the occurrence of diseases. The water quality characteristics of biogas slurry make crops absorb extremely quickly, which has both quick-acting and slow-acting properties. The current biogas slurry is generally produced through anaerobic fermentation in a single fermentation tank. Due to the large capacity of the biogas tank, the raw materials used for anaerobic fe...
