Abstract

The invention relates to the field of plant fertilizer and provides a nutrient solution suitable for high-yield soilless culture of eggplants. Every 1 L of the nutrient solution comprises 223.9-279.8 mg of N, 68.3-81.2 mg of P, 385.8-501.4 mg of K, 60 mg of Ca and 24 mg of Mg, besides, the nutrient solution comprises micro elements including Fe, Mn, Cu, Zn, B and Mo, and the pH of the nutrient solution ranges from 5.8 to 7.3. During preparation, potassium nitrate, calcium nitrate and ammonium nitrate are dissolved together and added to a liquid storage tank; ammonium dihydrogen phosphate or monopotassium phosphate and magnesium sulfate are dissolved together and added to the liquid storage tank, finally, the micro elements are dissolved together and added to the liquid storage tank until the volume of the mixture reaches a set value, the pH value is adjusted, the prepared nutrient solution is used for soilless culture of the eggplants, growth and development of the eggplants can be remarkably promoted, and the yield can be increased.

Description

technical field [0001] The invention relates to the field of plant fertilizers and provides a nutrient solution suitable for soilless cultivation of eggplants. Background technique [0002] The protected cultivation area of ​​eggplant in my country is gradually expanding, and it is second only to tomato, cucumber and pepper in the fruit and vegetable category. It is one of the important vegetables for domestic sales and foreign exchange earning in my country. Eggplant has a long growth period, high yield, and requires a large amount of fertilizer. The requirement for a large number of elements is mainly nitrogen fertilizer, followed by potassium fertilizer, and less phosphorus fertilizer. Among them, nitrogen and potassium fertilizers are the most needed in the fruit expansion stage, and more phosphorus fertilizers are needed in the seedling stage. [0003] In the eggplant production process, in order to obtain high yields and high benefits, vegetable farmers have prominent...
