Description
Technical field
The present invention relates to soil conditioning technical fields, a kind of soil conditioner more particularly to pbz polymer organic matter and
Preparation method.
Background technique
It is well known that soil is basis for the survival of mankind, it is to develop the economy and the most important resource of agricultural；Farmland is raw
State system is resolution exhausting waste, the substances such as carbon nitrogen sulphur phosphorus is maintained to recycle most important basis.However China arable land money
Source shortage is undisputable fact, and per capita area of cultivated farmland is few, populous, and many soil that should not be agricultural are opened up wasteland as farmland, is ploughed
Ground soil quality is integrally relatively low, and Middle and low production cropland accounts for 65%；High Farmland Conversion is too fast, and replenished cultivated land grade is relatively low, is filled with secondary
Good situation is very serious, and farmland quality totally declines, and has seriously affected the production capacity in China arable land, threatens China's grain peace
Entirely.In this sense, it is far from being enough for only keeping 1,800,000,000 mu of quantity of cultivated land, while also to guarantee farmland quality, it is ensured that
The steady promotion of productivity of cultivated land.
Soil conditioner refer to be added physics in soil for improving soil and (or) chemical property and (or) biology is living
The material of property.The dosage form of soil conditioner generally has pulvis, particle and aqua, and most at present is pulvis, but pulvis is in the presence of as follows
Problem: easily fly upward drift first is that manually spreading fertilizer over the fields, it is extremely difficult to guarantee amount of application and the uniformity, often because part excess cause soil block or
Local calcification, it is unfavorable to crop root and edaphon growth, and also large labor intensity, low efficiency, environment are poor；Second is that powder
Agent can not carry out do mechanization operation, increase cost of labor.The soil conditioner manufacture craft of granule is relative complex, needs to add
A series of auxiliary agents such as binder are granulated, and production efficiency is low, higher cost.The soil conditioning product of aqua have it is instant, apply
With the advantages that uniform, efficiently convenient, can be applied by service conduit with fertilizer；Aqua production cost is low simultaneously, without drying
Dry to be granulated, production environment cleaning, there is no the emission problems such as dust, smog, waste water, waste residue.
Polyacrylamide (PAM) is that Recent study is more, most representative soil conditioning substance, it is preventing water and soil
Loss, retain water and nutrients etc. application effect are significant.Polyacrylamide (PAM), guarantor are utilized in patent CN201410019940.5
Aqua (SAP) or the two, which are mixed, to be applied, and pulvis soil conditioning product is obtained；Needed when use by dry powder polyacrylamide (PAM) with
Soil spreads fertilizer over the fields earth's surface by the weight ratio of 1:20 after mixing, not only operates time-consuming and laborious, while being difficult to ensure application uniformity,
Execute-in-place environment is poor, dust is big.By polyacrylamide (PAM) and crop material hydrolysate in patent CN200910079403.9
It is mixed in a certain ratio, obtains the soil conditioning product of pulvis；Both can directly be applied when use, can also wiring solution-forming application, but
When solution application is prepared in selection, polyacrylamide (PAM) needs are dissolved in the water on the day before mentioning, to guarantee that it is completely dissolved, nothing
Method is accomplished ready-to-use, and preparation time-consuming is cumbersome.It is by polyacrylamide (PAM) and its in patent CN201410150439.2
He mixes substance, and then roller is granulated, sieves, and the granular soil conditioner of partial size 2.00mm-3.00mm is finally made,
Production technology is complicated, increases prilling, while also improving production cost.
To solve the above problem existing for soil conditioner, a kind of not only efficient but also easy to use liquid-type is developed containing poly- third
The soil conditioner of acrylamide (PAM) lotion is necessary.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of soil conditioner and preparation method thereof, the soil conditioning
