preparation example Construction

[0029] The embodiment of the present invention also provides a preparation method of the above-mentioned growth-regulating type citrus orchard acidic soil conditioner, comprising the following steps: adding quick-acting acid-modifying substances, slow-acting acid-modifying substances, root-promoting substances, magnesium-containing substances, and boron-containing substances And zinc-containing substances, mixed and granulated.

[0030] Specifically, the preparation method of the growth-regulating type citrus orchard acidic soil special conditioner comprises the following steps:

[0031] (1) Mixing substances containing quick-acting acid-modifying substances, slow-acting acid-modifying substances, root-promoting substances, and substances containing magnesium, boron, and zinc elements according to a preset ratio, and placed in a granulator for granulation;

[0032] (2) Spray the granulation caking substance solution in the granulator for granulation. If the granulation size is...

Embodiment 1

[0039] Weigh 100 kg of slaked lime, 40 kg of dolomite, 5 kg of thalassin, 50 kg of magnesium sulfate, 18 kg of borax, and 1.25 kg of zinc sulfate, pulverize and mix well, and spray 1.0L in a granulator with a concentration of 2%. The sodium silicate solution is granulated to obtain an acidic soil conditioner with a mass percent content of 4.7-0.9-0.2 of magnesium, boron and zinc and 2.3% of root-promoting substances.

Embodiment 2

[0041] Weigh 100 kg of soda lime, 80 kg of limestone powder, 10 kg of sea bath element, 100 kg of magnesium sulfate, 36 kg of borax, and 2.5 kg of zinc sulfate. % sodium silicate solution for granulation to obtain an acidic soil conditioner with 6.0-1.2-0.3 mass percentages of magnesium, boron, and zinc and 3.0% root-promoting substances.

Abstract

The invention discloses a growth regulation and control type conditioner special for acidic soil of a citrus orchard, a preparation method and application. The soil conditioner is composed of a quick-acting acid modifying substance, a slow-acting acid modifying substance, a root-promoting substance, secondary element magnesium, trace element boron and trace element zinc, wherein the mass ratio ofthe quick-acting acid modifying substance, the slow-acting acid modifying substance, the root promoting substance, the secondary element magnesium, the trace element boron and the trace element zinc is 1:(0.4-0.8):(0.05-0.1):(0.1-0.2):(0.02-0.04):(0.005-0.01). The soil conditioner provided by the invention has the outstanding advantages of improving the pH value of soil, correcting citrus nutrientdeficiency yellowing, preventing nutrient soil fixation, promoting citrus root growth, improving citrus fruit quality and the like.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, and in particular to a growth-regulated citrus orchard special conditioner for acidic soil, a preparation method and application. Background technique [0002] The pH value of red soil and yellow soil widely distributed in South China and Southwest my country's citrus producing areas is mostly between 4.5 and 5.5, but the most suitable soil pH for citrus growth is 5.5 to 6.5, the soil is acidic, aluminum toxicity is intensified, and exchangeable base nutrients The lack of ions seriously affects the absorption efficiency of citrus roots to soil nutrients. In citrus cultivation, the application of lime can alleviate the degree of soil acidification, but because the application of powdered lime is extremely inconvenient, the acceptance is generally not high. In addition, citrus orchards generally suffer from the lack of medium and trace elements, such as magnesium, boron, zinc and othe...
