To confirm the method, a collection of autogenous shrinkage and compressive energy of concrete with and with out super absorbent polymer (SAP) had been evaluated in contrast with the strategy proposed previously. Using humic acid extracted from Sinkiang Hami brown coal as raw material,and acrylic acid and acrylamide as monomer,PSA-AM polymer was synthesized by the method of solution copolymerization.Based on PSA-AM,a brand new super absorbent polymer was synthesized by means of adding humic acid and fly ash.The brand new polymer had properly capacity of retaining and adsorbing water,and will promote plant growth,and enhance soil physi-chemical properties.Meantime,its cost was lower comparatively.Thus,the brand new polymer had an excellent financial and use worth. Pre-swelling the crystals is a graphic illustration of their water holding capability. The crystals are sewn right into a pouch within the cloth. As these zones are ever facing water disaster resulting from inadequate and unsure natural precipitation, the issue with water scarcity or insufficiency may presumably aggravate supplementarily. The quantity of IC water is greatly necessary to shrinkage and power, because it might have an effect on the water and cement ratio () change, which is among the essential parameters in concrete combine proportion. 20 cm respectively. Application of super absorbent might accelerate or delay the change of most important water uptake layer in numerous intervals, but couldn't change the trend; The super absorbent polymer may considerably(P 0.05) improve the proportion of positive root(diameter 0.5 mm), selling root progress and bettering the basis water uptake efficiency; Treatments which super absorbent polymer were buried in shallow depth may promote the foundation growth more significantly, SAP and SAP15 had been better than SAP35; The super absorbent polymer impact on proportion of maize tremendous root(diameter 0.5 mm) was according to the regulation of root important water uptake layer change, which was obtained from stable isotopes evaluation.

Drought stress was utilized at fourteen-leave-stage of sunflower and polymer was added at the same stage to soil in depth of root development. However, polymer utility reduced the dangerous effects of drought stress whereas application of 300 kg/ha polymer in long irrigation intervals an inexpensive seed yield obtained. In all traits, a big decrease was observed with improve in stress stage. The seedling progress of handled with the compound-SAP was 12-47 percent higher than that of the reference, and the biomass of the group treated with the compound was 1.3-5.6 instances larger than that of the reference; the handled with compound SAP was in a position to important enhance water content and circulate of water of plant; the biomass of the group with the same level of fertilizer remedy was 3.88 times higher than the common. The proportion of superior tobacco significantly elevated, whereas the proportion of inferior tobacco significantly decreased, and the net output value of the flue-cured tobacco significantly increased by the remedy with software charge of 60 kg/hm2. The soil bulk density of 0-20 and ＞20-forty cm soil layers was significantly decreased by the remedy with utility charge of 60 kg/hm2, but the remedies with utility rate of 45 and seventy five kg/hm2 had no significant impact on soil bulk density.

In sum, the acceptable software fee of potassium polyacrylate tremendous absorbent ploymer is about 60 kg/hm2 within the tobacco discipline with yellow brown soil in Qinba mountain space. sodium acrylate uses of potassium polyacrylate super absorbent polymer promoted the expansion of flue-cured tobacco, elevated flue-cured tobacco yield, conventional chemical composition and output value. The increase of the amount of the super absorbent polymer within the concrete mix improves the interior curing properties of the concrete at the same generate more voids in the mass of the concrete which in flip reduces the strength of the concrete. Super-absorbent polymer (SAP) is ready to absorb water by a number of instances more than its personal weight. The greatest proline accumulation (4.001 mg/g dry weight) belonged to irrigation after 200 mm evaporation with 120 kg/ha of polymer, and the minimum leaf proline content (0.748 mg/g dry weight) was noticed at irrigation after one hundred mm evaporation with 300 kg/ha of polymer.

At the same time, it increased the dry matter accumulation and nutrient uptake. All the identical consept. The T3 for 200 g SAP per tree improved the typical soil moisture by about 21.53% as in comparison with T1 in the entire fruit period, and increased average diurnal transpiration by about 20.62%. At the same time, the average weight and Vitamin C content of each apricot fruit had been apparently increased than those of T1 and T2. Sapwood circulate velocity (SFV) of a 15-12 months-old apricot tree was repeatedly monitored by Thermal Dissipation Sapwood Flow Velocity Probe at Beiliu orchard in Changping. The authors researched soil water, transpiration, fruit yield and quality after making use of SAP to apricot trees and quantitatively analyzed water using characteristics, and the analysis offered a theoretical basis for highly efficient and reasonable water conservation. M. Javad Rousta. 2011. Effect of drought stress and animal manure with super absorbent polymer on yield and its components of Corn. Application of a decrease dose of polymer (seventy five Kg/ha) moderated the unfavorable results of drought stress, whereas higher doses of the polymer (225 and 300 kg/ha) prohibited the dangerous effects of drought stress. Matricaria chamomilla, and the effect of super absorbent polymers on reduction of drought stress, a factorial experiment was performed primarily based on randomized full block design with three replications in Faculty of Agriculture of Urmia University on 2008. Treatments included water deficit stress (irrigation after 50, 100, a hundred and fifty and 200 mm evaporation from pan class A) and varying quantities of super absorbent polymer (0, 60, 120, 180, 240 and 300 kg/ha).
