Embodiment 1
[0031] Embodiment 1: Eggplant full price special nutrient solution, the concentration of each nutrient element in the nutrient solution is as follows:
[0032] N: 252PPM
[0033] P: 52PPM
[0034] K: 510PPM
[0035] Ca: 105PPM
[0036] Mg: 46PPM
[0037] Fe: 3.3PPM
[0038] Mn: 0.35PM
[0039] B: 0.43PPM
[0040] Cu: 0.02PPM
[0041] Zn: 0.03PPM
[0042] Mo: 0.03PPM
[0043] Preparation of nutrient solution: Calculate the weight of various compounds required according to the concentration of the above nutrient elements in the nutrient solution, weigh them accurately, and make a concentrated nutrient solution first. When it is necessary to irrigate and fertilize the eggplant, dilute the concentrated solution with water 100 times to the required concentration, and apply it to the root area of the eggplant by drip irrigation. The harmless treated edible fungus waste residue is used as the cultivation substrate. Planting in common soil was used as a control, and the s...
Embodiment 2
[0044] Embodiment 2: eggplant full-price special nutrient solution, the concentration of each nutrient element in the nutrient solution is as follows:
[0045] N: 324PPM
[0046] P: 68PPM
[0047] K: 335PPM
[0048] Ca: 133PPM
[0049] Mg: 57PPM
[0050] Fe: 4.2PPM
[0051] Mn: 0.4PPM
[0052] B: 0.5PPM
[0053] Cu: 0.02PPM
[0054] Zn: 0.04PPM
[0055] Mo: 0.02PPM
[0056] In the same greenhouse, use the nutrient solution prepared in Example 1 and Example 2 and the organic matrix to cultivate eggplants; meanwhile, use ordinary soil as a contrast, and the amount of fertilizer applied is the same as that in Example 1 and Example 2; daily management measures same.
[0057] The application effect of above embodiment 1~2 and contrast is as follows:
