Embodiment 1
[0014] A soil phosphorus activator with a root-promoting effect, comprising the following components in parts by weight: 25 parts of polyaspartic acid, 25 parts of polyglutamic acid, 30 parts of itaconic acid, 9.5 parts of sorbitol, lemon 9.5 parts of acid, 1 part of iminodisuccinic acid.
[0015] Take itaconic acid, polyaspartic acid, polyglutamic acid, sorbitol and citric acid, dry, grind, sieve, dissolve in water, add iminodisuccinic acid, mix and disperse, and spray dry to obtain powdery high-efficiency accelerator Root-type phosphorus activator.
Embodiment 2
[0017] A soil phosphorus activator with a root-promoting effect, comprising the following components in parts by weight: 25 parts of polyaspartic acid, 25 parts of polyglutamic acid, 30 parts of itaconic acid, 9.5 parts of sorbitol, lemon 9.5 parts of acid, 1 part of [9,9-bis(2-ethylhexyl)-9H-fluorene-2,7-diyl]diboronic acid.
[0018] Take itaconic acid, polyaspartic acid, polyglutamic acid, sorbitol and citric acid, dry, grind, sieve, dissolve in water, add [9,9-di(2-ethylhexyl)-9H-fluorene- 2,7-diyl]diboronic acid, mixed and dispersed, and spray-dried to obtain a powdery high-efficiency root-stimulating phosphorus activator.
Embodiment 3
[0020] A soil phosphorus activator with a root-promoting effect, comprising the following components in parts by weight: 25 parts of polyaspartic acid, 25 parts of polyglutamic acid, 30 parts of itaconic acid, 9.5 parts of sorbitol, lemon 9.5 parts of acid, 1 part of 4-nitrophenyl-β-D-cellobioside.
[0021] Take itaconic acid, polyaspartic acid, polyglutamic acid, sorbitol and citric acid, dry, grind, sieve, dissolve in water, add 4-nitrophenyl-β-D-cellobioside, mix and disperse , and spray-dried to obtain a powdery high-efficiency root-promoting phosphorus activator.

technical field [0001] The invention relates to the field of agricultural technology, in particular to a soil phosphorus activator with biostimulating effect, which can activate phosphorus in soil and can promote the growth of plant roots. Background technique [0002] The deficit of phosphorus in my country's farmland soil has turned into a surplus since the late 1970s, and the surplus has increased from 6.1kg P·hm-2 in the early 1980s to the current 26.1kg P·hm-2. At present, my country is one of the countries with the most serious phosphorus surplus in the world. A large amount of phosphorus remains in the soil. Under the conditions of rainfall and irrigation, it will cause leaching year by year, causing non-point sourcepollution. Moreover, phosphorus remains in the soil with low activity and cannot be absorbed and utilized by plants. As a result, farmers still need to continuously add phosphorus fertilizers, which increases the cost of planting and causes serious waste...
