Abstract
The invention relates to a technique for manufacturing plant-root water-storing agent, and its characteristic is polymerized of the raw materials with acrylic acid as the main component, buried at the plant root, and for absorbing large amount of precipitation and store the precipitation at the root, during the drought and water lack, the plant can absorb the stored water for growing. It can be long-termly used and has the characters of automatically water -absorbing and -releasing function, simply producing, low cost, no pollution, no public hazard, etc.
Description
One, technical field
The present invention relates to a kind of plant growth accelerator, the especially a kind of plant root retaining agent manufacture method that can supply with plant root moisture content for a long time.
Two, background technology
Along with national project of conceding the land to forestry, the implementing in full of six big class Forestry Engineerings such as three Norths shelter-forest project, the afforestation project will be implemented in water-deficient areas such as arid, hillside fields, desert, desertes on a large scale.The fact is for a long time told people, and lack of water is the principal element that the afforestation nursery stock is difficult to survive.For nursery stock survives, people want to have use up way, even fetch water from afar to the nursery stock pouring, but still can not improve plant percent; Because a nursery stock survives and needs the water of 1000kg to satisfy growth needs, and need long-time continual maintenance plant root soil water content between 10-27%, can normal growth, but the arid area can not be satisfied the needs that nursery stock survives in this way.
The present invention is a kind of degradable plant root retaining agent that repeats to absorb water and release water that has.This agent is applied plant root, in the soil that is kept at plant root that it can be firm with a large amount of precipitation, when arid, slowly release moisture content then again, for seed germination and seedling growth.Therefore, the use of this agent can improve the surrival rate of afforestation and can save the labor force in a large number.
Three, summary of the invention
Applicable raw materials and weight proportion: 10 parts in vinylformic acid, 7.5 parts of 25% ammoniacal liquor, 0.05 part of ammonium persulphate, 9 parts in tap water, nitrogen is an amount of.
Vinylformic acid, colourless transparent liquid or yellow liquid, water-soluble, easily aggregate into white powder, be the basal component of this agent.Use technical grade vinylformic acid.
Ammoniacal liquor, promptly oxyammonia is used as neutralizing agent in this agent, uses with vinylformic acid in supplying.Ammoniacal liquor with content 25%.
Ammonium persulphate is used as initiator in this agent.Use the technical grade ammonium persulphate.
Nitrogen, the air in this agent is produced in the metathesis reactor, mild provide protection reacts.
The present invention is in the reactor of strap clamp cover, add entry and vinylformic acid, be stirred to complete molten after, add ammoniacal liquor and mix, add ammonium persulphate then, after mixing, feed nitrogen replacement again after, heat temperature raising to 55 ℃ beginning polymerization, and kept this temperature about 1 hour, polymerization is finished, promptly get water insoluble, and suction and the plant root retaining agent of swelling.
Four, embodiment
Embodiment one: in the reactor of strap clamp cover, add entry 9kg and vinylformic acid 10kg stir complete molten after, adding ammoniacal liquor 7.5kg neutralization again mixes, after adding ammonium persulphate 0.05kg then and mixing, feed nitrogen replacement, reheat to 55 ℃ polyreaction 1 hour promptly makes plant root retaining agent.
Claims (2)
1. a plant root retaining agent technology of preparing is characterized in that raw material by 10 parts in vinylformic acid, 7.5 parts of 25% ammoniacal liquor, and 0.05 part of ammonium persulphate, 9 parts in tap water, nitrogen is formed in right amount.
2. as claims 1. described a kind of plant root retaining agent technologies of preparing, it is characterized in that with raw material add by proportioning mix in the reactor of strap clamp cover after, logical nitrogen replacement also is heated to 55-60 ℃ of polyreaction and made in 1 hour.
