Problems solved by technology

[0002] As representatives of efficient and cheap plant growth retardants, substances such as paclobutrazol and chlormequat have been widely used for a long time, but their dosage control is imprecise, and their application is relatively extensive. Excessive application can easily cause excessive growth inhibition, resulting in stunted plant development and green seedling necrosis
Chinese patent 981250165 discloses a slow-release lawn fertilizer with a spherical inner membrane. Although the release of paclobutrazol can be controlled and the soil residue problem is solved to a certain extent, it is easy to cause phytotoxicity to plants due to the use of a single growth regulator.

Embodiment 1

[0012] Group ratio:

[0013] Nutrients (potassium chloride, borax) 30 grams,

[0014] Plant growth retardant (uniconazole, paclobutrazol) 0.05 g,

[0015] Plant growth promoter (naphthaleneacetic acid, benzylaminopurine) 0.08g,

[0016] Controlled release carrier (10% humic acid, 90% lignin) 69.87 grams.

[0017] Grind potassium chloride and borax to less than 0.1mm, dissolve the plant growth retardant and plant growth regulator with a small amount of alcohol and then dilute it into a 0.2% aqueous solution, add nutrients and controlled release carrier, stir evenly, extrude and granulate , after drying, the present invention has a cylindrical shape with a length of 3 mm and a diameter of 1 mm.

[0018] Apply the above fertilizer to the mixed vegetation of tall fescue and bermudagrass on the side slope of the highway, and the dosage is 3 grams / m 2 , After fertilization, the lawn will be green in color, low in height and strong, dense in root system, and its resistance will b...

Embodiment 2

[0020] Group ratio:

[0021] Nutrients (potassium sulfate, potassium borate, urea) 40 grams,

[0022] Plant growth retardant (uniconazole, paclobutrazol) 4 grams,

[0023] Plant growth promoter (indole butyric acid) 5 grams,

[0024] Controlled release carrier (75% humic acid, 15% lignin) 51 grams.

[0025] All the other operations are the same as in Example 1 to obtain the granularity of the present invention with a particle size of 1 to 4 mm.

[0026] Apply the above-mentioned fertilizer to the peach tree at an amount of 6 g / m 2 , After application, the branches of fruit trees will be reduced, the fruit trees will be low and strong, the root system will be dense, the resistance will be improved, and the frequency of fertilization will be reduced. After one application, it can last for more than one year, and the fruit setting rate will increase by 30%.

Embodiment 3

[0028] Group ratio:

[0029] Nutrients (potassium carbonate, sodium pentaborate, magnesium chloride) 15 grams,

[0030] Plant growth retardant (chlormequat) 0.5 g,

[0031] Plant growth promoter (naphthalene acetic acid, indole butyric acid) 0.5 g,

[0032] Controlled release carrier (humic acid 40%, lignin 60%) 84 grams,

[0033] All the other operations are the same as in Example 1 to obtain the granularity of the present invention with a particle size of 1 to 4 mm.

[0034] Apply the above fertilizers to the chrysanthemums at an amount of 2 g / m 2 , After application, the color of leaves and flowers is beautiful, and the flowering period is extended for 15 days. At the same time, it prevents the branches from growing wildly, the plant shape is beautified, and the ability to resist diseases and insect pests is improved. Compared with conventional fertilization, the frequency of fertilization is reduced by more than half.

Abstract

The invention provides a fertilizer with release-controlled function for strengthening root and inhibiting growth, which comprises the components of (by weight ratio) nourishing substance 15-40, plant growth retardant 0.05-5, plant growth accelerator 0.05-5, controlled release carrier 50-84. The fertilizer has the functions of delaying vegetation, dwarfing the strains, accelerating tillering, root generating, reinforcing cold resistance, drought resistance, and minimizing soil residual quantity of growth regulator.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a root-strengthening, growth-inhibiting, and controlled-release functional fertilizer. Background technique [0002] As representatives of efficient and cheap plant growth retardants, substances such as paclobutrazol and chlormequat have been widely used for a long time, but their dosage control is imprecise, and their application is relatively extensive. Excessive application can easily cause excessive growth inhibition, resulting in stunted plant development and green Seedling necrosis and so on. Chinese patent 981250165 discloses a slow-release turf fertilizer with a spherical inner membrane. Although the release of paclobutrazol can be controlled and the soil residue problem is solved to some extent, it is easy to cause phytotoxicity to plants due to the use of a single growth regulator. Contents of the invention [0003] The object of the present invention is to overcome the above-mentione...
