Description
Technical field:
The present invention relates to a kind of water-loss reducer of soil, relate to a kind of water-loss reducer of soil and preparation method thereof more specifically.
Background technology:
1,500,000,000 mu of China's total area under cultivations, wherein the nonirrigated farmland area is 5.7 hundred million mu, accounts for 38% of national cultivated area, also have large-area deserted mountain in addition, xerocline afforestation district is because rainfall amount is on the low side, and distributed pole is inhomogeneous, directly affects the raising of agriculture production and the surviving rate of afforestation trees; In addition, China is the country that a water resources lacks, promptly enable the paddy field irrigated, also often suffer from no anti-ly, cause the underproduction because of insufficient water sources, the solution route of the problems referred to above removes develop actively water conservancy construction cause, outside the water saving irrigation agricultural, utilize new high-tech product to solve drought resisting, water conservation, protecting fertile problem, is one of effective way of development agricultural and forestry production.
Water-holding agent at farming, forestry such as water-saving moisturizing, soil improvement, seed pelleting, nursery stock is dipped in aspects such as root, preserving fruit and vegetable utilizing that boundless application prospect is arranged.Because the cost of general water-holding agent is higher, and salt tolerant alkalescence and specific aim are relatively poor, have limited its applying at aspects such as agricultural, gardening.
The inventor discloses a kind of water-loss reducer of soil and manufacture method thereof in the patent ZL97101028.5 of application on January 21st, 1997, it comprises that raw materials such as vinylformic acid, Potassium Persulphate form through reaction, product has water-absorbent preferably, and contains the required nutritive element of crop.Yet, find owing to the factors such as raw material that adopted that its preparation process is complicated through the inventor's practice for many years, the reaction times is very long, and is unfavorable to producing.
More than 8 years, on the basis of applying for a patent January 21 in 1997, the contriver has done improvement test repeatedly to production technique and production method, further refinement production technique, technique manufacturing method after the improvement has strong points such as more simple and efficient, that the production frock is simple, the direct labor is easy to operate, has remedied the defective of former complicate fabrication process, long reaction time.
Summary of the invention
One of purpose of the present invention is to overcome the deficiencies in the prior art, and a kind of water-loss reducer of soil that has both the retaining water conservation and the plant-growth desired nutritional is provided is provided.
Two of purpose of the present invention provides a kind of preparation method of water-loss reducer of soil.
These and other objects of the present invention will further be launched and illustrate by following detailed.
Water-loss reducer of soil of the present invention is that a kind of polymer organic polymer is a main raw material with vinylformic acid, sodium hydroxide, starch, zinc sulfate etc., and the technical process of employing new technology forms through polyreaction.

Water-loss reducer of soil of the present invention is prepared as follows: raw material propylene acid, starch, glycocoll and borax are carried out polyreaction at normal temperatures, react and add initiator potassium persulfate after 0.5 hour, catalyzer sodium hydroxide, under 70 ℃, proceeded secondary reaction 4 hours, discharging, drying and dewatering, and be crushed to 0.25mm, add conventional fertilizer then, packing is finished product.
In the present invention, the chemical constitution of this water-holding agent and component effect:
Vinylformic acid: the main raw material of polyreaction also is the basis of reaction, and its polymer is a high absorbency material;
Sodium hydroxide: the catalyzer of polyreaction;
Potassium Persulphate: initiator of polyreaction;
Starch: reduce the polymer beads diameter, make molecule refining; Increase the nutritive element of water-retaining capacity and plant;
Glycocoll: the high protein material increases the polymer organic composition;
Conventional fertilizer: i.e. nitrogen phosphorus potassium and trace element fertilizer are the required important nutrients of plant-growth.
Product appearance of the present invention is faint yellow powder shape, and effective component content reaches more than 95%.This product can absorb water rapidly when meeting water, molecule expands and reaches more than 350 times, back receivability natural rainfall or manually water is manured into soil, also can absorb airborne moisture, improve soil suction and water retention capacity, reduce the velocity of evaporation of moisture content in the soil, thereby increase the content of soil available water, moisture content is gradually by plant absorbing when meeting drought, improve water and fertilizer utilization, so it is a kind of more satisfactory plant water keeping agent, through after the scientific experiment under the different condition, this product also has the soil physical chemistry of improvement performance, chessom promotes soil aggregate to form, and reconciles P in soil H value, improve soil mineral and biological activity nutrient, thereby can effectively improve utilization rate of fertilizer, slow down water evaporates speed, reconcile soil humidity.Use this product generally can improve the soil moisture utilization ratio more than 30%, improve utilization rate of fertilizer 10-20%.
The product of the present invention multiple that absorbs water after testing is 350-450 (gram weight), and PH is 6.5～7, particle diameter 0.25～0.4mm, nutritive element content 5-10wt%.
Compared with prior art, water-loss reducer of soil of the present invention has the following advantages:
1, the characteristics that have high-strength absorbing and use repeatedly, after being manured into soil, the receivability natural rainfall manually waters, and can also absorb airborne moisture, and after treating fully to adsorb, volumetric expansion can reach (weight ratio) more than 400 times.
2, improve the water-retaining capacity of soil, and natural precipitation can be kept in the soil securely, reduce the evaporation of moisture content in the soil simultaneously, thereby therefore the effect of playing water saving, preventing erosion has good retaining water retention property.
3, the water-loss reducer of soil structure of improving the soil in addition simultaneously improves soil permeability and water-holding power, can make loosing soil, promotes soil aggregate, and soil is not hardened.
4, have reduction soil salinity and alkalinity (belonging to alkalescence because of northern soil is most of), improve water and fertilizer utilization and reach water collection and keeping, keeping crop seedling from drought, the purpose of increasing both production and income.
5, water-loss reducer of soil of the present invention, the effect that not only has preserve moisture and fertility, and contain the required main nutrient elements of farm crop, field-crop can increase production 10-20% after using, use when cash crop vegetables, flowers turf and Greening Urban Road are planted and can improve surviving rate 30-70%, semiarid land half arid area and barren hill are planted trees to use and can be improved surviving rate 20-70%.
6, have wide range of applications, this product can also be used for oil, chemical industry, medical and health, fruit fresh-keeping and industry dehydration and environment protection aspect.
