Problems solved by technology

However, some sloping vegetation and orchards do not have the conditions to install such water-saving projects. Coupled with the lack of water resources and the harvest "depending on the sky", water use for many sloping orchards and garden vegetation has become a problem.

preparation example Construction

[0037] The present invention also provides a preparation method for the above-mentioned medium and trace element fertilizer, comprising the steps of:

[0038] (1) Add water, magnesium nitrate, sulfate and borate to the reaction kettle in turn according to the proportion of the raw materials, and adjust the pH value to 3.0-4.0 to make it slightly acidic, so that calcium is added in the next step In the process of salt, it can avoid calcium sulfate combined with precipitation, causing colloidal sedimentation to be destroyed. The above-mentioned process temperature can be controlled at 50°C-60°C, and the rotation speed is 20-25r / min, so as to ensure the rapid dissolution of the above-mentioned raw materials.

[0039] (2) Add calcium ammonium nitrate and alginate, control the temperature at 60°C-70°C, and rotate at 10-15r / min. In this step, when the temperature is set at 60°C to 70°C, the dissolution between calcium ammonium nitrate, alginate and magnesium nitrate, sulfate and bo...

Abstract

The invention discloses a medium trace element fertilizer which comprises the following components: 0.1-0.5 part of alginate, 30-40 parts of calcium ammonium nitrate, 10-15 parts of magnesium nitrate, 7-20 parts of sulfate, 5-10 parts of sodium borate and 25-50 parts of water. The preparation method comprises the following steps: according to the ratio of the raw materials, sequentially adding water, magnesium nitrate, sulfate and borate into a reaction kettle, adjusting the pH value, and controlling the temperature to be 50-60 DEG C and the rotation speed to be 20-25r/minute; further adding calcium ammonium nitrate and sodium alginate, controlling the temperature to be 60-70 DEG C and the rotation speed to be 10-15r/minute; after a gel is formed, increasing the rotation speed to be 40-50r/minute, and drying. The alginate fused with a biological source is beneficial for a saturated fertilizer solution to form the gel, medium trace elements can be prevented from being fixed by soil, the effect of slow and controlled release of nutrients can be achieved, the moisture utilization rate can be increased, and the medium trace element fertilizer can be also used as a liquid fertilizer additive. The invention further provides application of the medium trace element fertilizer.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a colloidal fertilizer of medium and trace elements used for fruit trees and garden economic crops, as well as its preparation method and application. Background technique [0002] At the beginning of 2015, my country's medium and low-yield fields accounted for more than 70% of the total cultivated land area. Due to the long-term excessive use of N, P, K and other constant element fertilizers in some high-yield fields, the soil quality has deteriorated, and the increase in yield has been limited. Targeted application of medium and trace element fertilizers is an effective technical measure to increase the yield of medium and low-yield fields, and it is also an important means to maintain continuous increase in high-yield fields. At the same time, crops can only absorb ionic elements that are soluble in water, while anions in the soil are easy to fix cationic mediu...
