<p> In order to study the effects of soil textures and super absorbent polymer rates on yield of flower, corm and stigma and other growth characteristics of saffron, an experiment was conducted as factorial based on a randomized completed block design with three replications at the outdoor area of the greenhouse of College of Agriculture, Ferdowsi University of Mashhad during two years of 2010 and 2011. https://www.storeboard.com/blogs/help-for-homeowners/the-untold-secret-to-mastering-super-absorbent-polymer-in-just-5-days/5011308 were three soil textures in fine to coarse ranges such as sandy loam, loam, clay loam and super absorbent polymer rates such as zero, 0.1, 0.2, 0.4 and 0.8 weight percentage based on dry weight of soil. With laboratory test and field experiment, this paper studied the water conservation performance of four types of super absorbent polymer (SAP) in deionized water and loam soil, and the effects of the type and dosage of SAP on the soil water storage and maize yield. In this paper,the super absorbent polymer(SAP)was fast polymerized at high temperature with using starch as the skeleton,acrylic acid(AA)as monomers,potassium persulfate(K 2S 2O 8)n as the initiator.The best formula was obtained by orthogonal experiments,and the products exhibited values of 1550 g H 2O/g sample in deionized water and 95 g H 2O/g sample in deionized oater and 95 g H 2O/g sample in 0 9 wt% NaCl solution.</p>
<p> 40%, in which the distilled water absorbency of the product reached its maximum of 509 g/g and the grafting reaction time approached its minimum of 2min. This process has the advantages of simple operation, easy control, high grafting efficiency, short production cycle, low cost and so on, which meet the industrial production requirements of super absorbent polymer. The effects of discharge power, plasma treatment time, initiator dosage, acrylic acid dosage, vacuum degree and neutralization ratio on water absorbency and grafting reaction time of the products were studied by single factor experiments. A novel antibiotic super-absorbent polymer was synthesized from cassava starch,acrylic acid,and capsaicin by graft copolymerization in aqueous solution using ammonium persulfate and sodium bisulfate as initiator and N,N'-methylene biacrylamide as cross-linking agent.The effects of reaction conditions on water absorption of the product were investigated.The results showed that the product had good water absorption under the following conditions:adding extraction of capsaicin,reaction temperature 70 ℃,reaction time 2.5 h,neutralization degree of acrylic acid 85%,amount of initiator and cross-linking agent 0.6% and 0.04% respectively. The highest yield of biomass (1215.55 kg/ha) was obtained from irrigation after 50 mm evaporation and 0 kg/ha of polymer application, and the lowest yield (164.44 kg/ha) was obtained from irrigation after 200 mm evaporation by using 120 kg/ha of polymer.</p>
<p> Thereafter, the upper solution in the high-speed centrifugal tube was filtered by using a 0.45 µm syringe filter, which was used by the water absorption test. Development status, absorption mechanism and performance characterization of super absorbent polymer (SAP) were introduced. Hollow glass microspheres were added during surface-crosslinking to improve the absorption properties and permeability of the SAP. Additionally, China’s largest nonwovens manufacturer, Toray confirms that it has added its fifth line, capable of making 20,000 tons of spunbond nonwovens per year, in China. One of the largest makers of nonwovens in Asia, Toray also makes 61,000 tons of the material in Korea and 37,000 tons per year in Indonesia and is planning to start production of an 18,000-ton-per-year line in India in 2020. This investment will bring the group’s total production capacity to 209,000 tons per year. Sugarcane bagasse (SCB) raw material has been excessively produced as a byproduct in sugar factory. Carboxymethyl cellulose (CMC) made from bagasse pulp was treated by low-temperature plasma, then reacted grafting polymerization with acrylic acid (AA) to produce super absorbent polymer. RAHMANI, M., HABIBI, D., SHIRANIRAD, A., DANESHIAN, J., VALADABADI, S., MASHADI AKBAR BOUJAR, M., KHALATBARI, A., 2010. THE EFFECT OF SUPER ABSORBENT POLYMER ON YIELD, ANTIOXIDANT ENZYMES (CATALASE AND SUPEROXIDE DISMUTASE) ACTIVITY AND CELL MEMBRANE STABILITY IN MUSTARD UNDER WATER DEFICIENCY STRESS CONDITION.</p>
<p> THE EFFECT OF SUPER ABSORBENT POLYMER ON YIELD, ANTIOXIDANT ENZYMES (CATALASE AND SUPEROXIDE DISMUTASE) ACTIVITY AND CELL MEMBRANE STABILITY IN MUSTARD UNDER WATER DEFICIENCY STRESS CONDITION. While, the effect of super absorbent polymer on was non significant dried flower, the numbers of capitol per plant, capitol diameter, receptacle height, single capitol weight and leaf soluble carbohydrates Interaction effect between water deficit and polymer was significant on the yield of biomass, chlorophyll a, b, total chlorophyll and proline. Results of Analysis of Variance (ANOVA) showed the significant effect of irrigation on dried flower, the numbers of capitol per plant, capitol diameter and receptacle height, and non significant effect on single capitol weight and leaf soluble carbohydrates. Their invention revolves around super moisture-absorbent gels (SMAGs) that are made with an ingredient called hygroscopic polymer that enables the gel to soak up water vapor suspended in the ambient air, and transform it into liquid irrigation for plants. In general, German chamomile tolerance to drought stress was through osmotic regulation of proline, and the yield of biomass was improved by super absorbent application.</p>
