Problems solved by technology

[0003] Compound fertilizers can be divided into general-purpose fertilizers and special-purpose fertilizers according to their uses. The former has its obvious disadvantages, mainly because the proportion of phosphorus or potassium is not appropriate, either there is too much phosphorus or too much potassium, resulting in waste
There is no literature report on special fertilizer for eggplant

Abstract

The invention provides a special irrigation fertilizer for eggplants planted with the following raw materials by weight: 25-35 urea; 10-20 ammonium diacid phosphate; 30-40 potassium sulfate; and 15-25 humic acid ammonium. The preparation method includes : crushing the raw materials to 150-200 mesh respectively; evenly mixing the raw materials in a certain proportion; finally measuring and product packaging. The special irrigation fertilizer for eggplants of the invention has a significant yield-increased and value-added benefit in practical applications and has a significant economic and social benefit. At the same time the fertilizer can improve soil environmental benefit, which is a sustainable and safe fertilizer for vegetable fields. The invention is a special eggplant fertilizer which is well-targeted and can be applied in eggplant planting areas throughout the country.

Description

1. Technical field [0001] The invention relates to the technical field of production of organic-inorganic compound special fertilizer, specifically an eggplant that basically meets the growth needs of eggplant developed according to the law of eggplant's nutrient demand and according to the regional soil nutrient status and loss situation. Special flush fertilization. 2. Background technology [0002] The amount of compound fertilizer application in China has accounted for about 22% of the total fertilizer consumption, but there is still a certain gap compared with the world average level of 30%, and the gap between the level of about 80% in developed countries is even greater. [0003] Compound fertilizers can be divided into general-purpose fertilizers and special-purpose fertilizers according to their uses. The former has its obvious disadvantages, mainly because the proportion of phosphorus or potassium is not appropriate, either there is too much phosphorus or too much ...
