Problems solved by technology

Drip irrigation and fertilization technology has been vigorously promoted abroad, but domestic application of drip irrigation and fertilization technology has just started. Although there are many liquid fertilizer varieties serving vegetable drip irrigation and fertilization technology on the market, there are generally strong versatility and poor specificity. Problems such as low nutrient concentration, incomplete nutrient, unreasonable ratio, poor water solubility and high cost cannot meet the requirements of vegetable drip irrigation and fertilization technology

Embodiment 1

[0033] Embodiment 1: in production tank, add the water of 12.5 parts earlier, then add 20 parts of phosphoric acid (P 2 o 5 62%), and then add 40 parts of potassium chloride (K 2 O 62%) and 15 parts of urea (N 46%), add 12.5 parts of water again in the production tank, stir until the fertilizer is completely dissolved, and cool to room temperature to obtain the product. N:P in this product 2 o 5 : K 2 O=1:1.80:3.59, N+P 2 o 5 +K 2 O = 44.1%.

Embodiment 2

[0034] Embodiment 2: add 25 parts of water earlier in production tank, then add 12 parts of phosphoric acid (P 2 o 5 62%), and then add 8 parts of potassium chloride (K 2 O 62%) and 30 parts of urea (N 46%), add 25 parts of water again in the production tank, stir until the fertilizer is completely dissolved, and cool to room temperature to obtain the product. N:P in this product 2 o 5 : K 2 O=2.78:1.50:1, N+P 2 o 5 +K 2 O = 26.2%.

Embodiment 3

[0035] Embodiment 3: add 23 parts of water earlier in production tank, then add 7 parts of phosphoric acid (P 2 o 5 62%), and then add 37 parts of potassium chloride (K 2 O 62%) and 10 parts of urea (N 46%), add 23 parts of water again in the production tank, stir until the fertilizer is completely dissolved, and cool to room temperature to obtain the product. N:P in this product 2 o 5 : K 2 O=1.06:1:5.29, N+P 2 o 5 +K 2 O = 31.88%.

Abstract

The related liquid composite fertilizer for vegetable drip irrigation comprises constituents with weight share as: 10-30 inorganic nitrogen fertilizer, 7-20 inorganic phosphatic fertilizer, 8-40 inorganic potassium fertilizer, and 25-50 water. The opposite preparation method comprises: 1) adding half of said water into the production tank and the phosphatic fertilizer; 2) adding aforementioned fertilizers by turns; 3) adding another half water to stir till full dissolution, and cooling to room temperature to obtain the product. This invention has strong special purpose, high nutrient concentration, and well water solubility.

Description

technical field [0001] The invention relates to the field of mixed fertilizers in agricultural production, in particular to a liquid compound fertilizer specially used for drip irrigation of vegetables and a preparation method thereof. Background technique [0002] Irrigation and fertilization are two important management measures in vegetable cultivation. Irrigation and fertilization are closely related. Only by combining irrigation and fertilization and maintaining the balance of water and fertilizer can we maintain the best water and fertilizer content in the soil space of the root zone of vegetables, and keep vegetables absorbing and utilizing nutrients under the most favorable conditions, so that vegetables It can obtain high yield and improve product quality under different soil conditions. The fertilization technology applied in the drip irrigation system, that is, drip fertigation, is a technology that can combine irrigation and fertilization and control the ratio b...
