<p> 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 new super absorbent polymer was synthesized through adding humic acid and fly ash.The new polymer had well capacity of retaining and adsorbing water,and could promote plant growth,and improve soil physi-chemical properties.Meantime,its cost was lower relatively.Thus,the new polymer had a good economic and use value. It’s extremely cost-efficient on the part of furrow irrigation systems, wherever it will be applied at a lower rate. The Conclusions show that: the compound-SAP has no significant effect on the emergence rate and is able to significantly increase seedling growth of annual ryegrass. F. chinensis. In general, application of super absorbent polymer in readily-available fertilizer improved the later growth of F. chinensis and prolonged quick accumulation period of dry matter, nitrogen and potassium. Results showed that super absorbent polymer addition had no effect on the early growth stage of F. chinensis, but increased the height and ground diameter during later growth stage, compared with readily-available fertilizer treatment only.</p>

<p> Compared with readily-available fertilizer treatment only, super absorbent polymer addition delayed the terminal time and extended the time of dry matter quick accumulation by seven days. Compared to A0, the compressive strengths of A1 and A2 were decreased by 12.1% and 13.0% at 3 days, while by 1.2% and 1.7% at 56 days. This extraction procedure was compared with the Japanese official method in which samples were dehydrated with 75 g of anhydrous Na2SO4 and extracted with ethyl acetate. The T3 for 200 g SAP per tree improved the average soil moisture by about 21.53% as compared to T1 in the whole fruit period, and increased average diurnal transpiration by about 20.62%. At https://www.empowher.com/users/breakstove7 , the average weight and Vitamin C content of every apricot fruit were apparently higher than those of T1 and T2. https://www.gamespot.com/profile/racingattic2/about-me/ -absorbent polymer (SAP) is able to absorb water by multiple times more than its own weight.</p>

<p> 20 cm respectively. Application of super absorbent could accelerate or delay the change of main water uptake layer in different periods, but could not change the trend; The super absorbent polymer could significantly(P 0.05) increase the proportion of fine root(diameter 0.5 mm), promoting root growth and improving the root water uptake performance; Treatments which super absorbent polymer were buried in shallow depth could promote the root growth more significantly, SAP and SAP15 were better than SAP35; The super absorbent polymer effect on proportion of maize fine root(diameter 0.5 mm) was consistent with the law of root main water uptake layer change, which was obtained from stable isotopes analysis. On the other hand, polymer application reduced the harmful effects of drought stress whereas application of 300 kg/ha polymer in long irrigation intervals a reasonable seed yield obtained. CONCLUSION: The highest increase in most examined traits obtained when 75 kg.ha-1 of super absorbent was used. The highest plant height, number and surface area of the leaf, fresh and dry weight and diameter of plant was related to irrigation after 4 days with 3% polymer application and the lowest was related to irrigation after 12 days with no application of polymer.</p>

<p> Three irrigation levels after 6 (I1), 10 (I2) and 14 (I3) days and five amounts of super absorbent polymer (0, 75, 150, 225, 300 kg/ha) were set as main and sub factors, respectively. METHODS: Current research was conducted with using a split-plot arrangement based randomized complete block design with three replications in research field of Islamic Azad University of Kaleybar, Iran in crop year 2017. Main plots included different irrigation regime at three level (D1: after 60mm, D2: 90mm and D3: 120mm evaporation pan class A) and different amounts of super absorbent polymer (S1Zero or control:, 75 kg.ha-1: S2 and 150 kg.ha-1: S3 super absorbent polymer; SAP) belonged to sub plots. The experiment was carried out in a split plot based on randomized complete block design with three replications. 1. Using the data in the table plot a line or bar graph of amount of liquid absorbed by the two absorbents along the Y-axis verses their names along the X-axis. The effects of super absorbent polymer on maize root growth and its water absorption characteristics were explored using stable deuterium and oxygen isotopes. Drought stress was applied at fourteen-leave-stage of sunflower and polymer was added at the same stage to soil in depth of root development.</p>
