Embodiment Construction

[0022] A slow-release additive for pear tree fertilizer containing brassinolide, which is made from raw materials of the following weight (kg):

[0023] Straw 20, coal gangue powder 6, brassinolide 0.4, amidinothiourea 1, glucose 1, polyethylene glycol 1.5, brown sugar 1, phosphogypsum 1, weathered coal 6, polyacrylamide 3, potassium nitrophenolate 0.2, polypropylene glycol 0.8, agricultural rare earth nitrate 3, sodium dodecylbenzene sulfonate 1, alfalfa 4, wild chrysanthemum 1, frangipani 1, chamaejasma 1, corn gluten powder 3, cow dung 3, HM decomposing agent 0.1 .

[0024] The preparation method of the pear tree fertilizer slow-release additive containing brassinolide comprises the following steps:

[0025] (1) Collect rice straw, dry it to make the water content less than 20%, then conduct pyrolysis carbonization at 520°C, cool, grind, and pass through a 1mm sieve to obtain straw biochar with a particle diameter of <1mm;

[0026] (2) After sieving the biochar, mix it wi...

Abstract

The invention discloses a pear tree fertilizer slow-release additive containing brassinolide. The pear tree fertilizer slow-release additive containing brassinolide comprises, by weight, 20-25 parts of rice straw, 4-6 parts of coal gangue powder, 0.2-0.4 part of brassinolide, 1-2 parts of guanylthiourea, 1-4 parts of glucose, 1-2 parts of polyethylene glycol, 1-2 parts of brown sugar, 1-2 parts of ardealite, 6-8 parts of weathered coal, 1-3 parts of polyacrylamide, 0.2-0.3 part of potassium nitrophenolate, 0.6-0.8 part of polypropylene glycol, 1-3 parts of agricultural rare earth nitrate, 1-2 parts of sodium dodecyl benzene sulfonate, 4-5 parts of alfalfa, 1-2 parts of flos chrysanthemi indici, 1-2 parts of plumeria rubra, 1-3 parts of stellera chamaejasme, 3-5 parts of corn gluten meal, 3-5 parts of cow dung and 0.1-0.3 part of HM decomposition maturing agent.

Description

technical field [0001] The invention relates to the field of fertilizer additives, in particular to a pear tree fertilizer slow-release additive containing brassinolide. Background technique [0002] For a long time, my country's chemical fertilizer application has the disadvantages of excessive application, nutrient loss, and low utilization rate of crops. Only 30% of the chemical fertilizers used in traditional agricultural production are absorbed by crops, and the rest are volatilized into the atmosphere or lost with water and soil, causing a large number of The loss of fertilizer also caused some pollution to the environment. [0003] Fertilizer additives, chemicals used to improve fertilizer performance, enhance fertilizer efficacy, decompose residual pesticides, nitrates, and improve the soil environment. Existing fertilizer additives have a single function and cannot fully meet the various requirements of various plant growth soils. [0004] Brassinolide is a new typ...
