Development of Algae-derived Biostimulants and Its Application in Fertilizers
Algae-derived biostimulants is widely distributed and environmentally friendly, which contains various mineral elements and organic active substances. It can not only be directly applied in crop cultivation, but also combined with fertilizer to produce seaweed fertilizer, which has broad market prospects. In order to improve the extraction efficiency of algal-derived biostimulants, accelerate the development of seaweed fertilizer production process, and promote the high-quality development of the seaweed fertilizer market, a review was conducted on the research progress related to the extraction and addition processes of algal-derived biostimulants. Firstly, the sources and active ingredients of algae-derived biostimulants were summarized. Secondly, the applications of algae-derived biostimulants in promoting plant growth, resisting stress and improving soil ecological environment were reviewed. The advantages and disadvantages of physical, chemical and biological extraction methods of algal derived biostimulants were introduced, and an efficient compound extraction process was proposed. Then, the application methods of algal-derived biostimulants in urea-based high tower compound fertilizer, nitro-based high tower compound fertilizer, water-soluble fertilizer and organic fertilizer were discussed. Finally, the development of the seaweed fertilizer industry was discussed and suggestions were put forward. At present, the seaweed fertilizer product market price is high, with poor production quality, and low market share. It is suggested to control the production cost of seaweed fertilizer through promoting technological innovation, optimize the seaweed fertilizer market environment through strengthening market supervision, and increase product promotion efforts through innovating technological services.

Phytosterols are a group of sterols exclusive to plants and fungi, but are indispensable to humans because of their medicinal and nutritional values. However, current raw materials used for phytosterols extraction add to the cost and waste in the process. For higher sterols production, major attention is drawn to plant materials abundant in phytosterols and genetic modification. To provide an insight into phytosterols metabolism, the research progress on key enzymes involved in phytosterols biosynthesis and conversions were summarized. CAS, SSR2, SMT, DWF1 and CYP710A, the enzymes participating in the biosynthetic pathway, and PSAT, ASAT and SGT, the enzymes involved in the conversion of free sterols to conjugated ones, were reviewed. Specifically, SMT and CYP710A were emphasized for their function on modulating the percentage composition of different kinds of phytosterols. The thresholds of sterol equilibrium and the resultant phytosterols accumulation, which vary in plant species and contribute to plasma membrane remodeling under stresses, were also discussed. By retrospective analysis of the previous researches, we proposed a feedback mechanism regulating sterol equilibrium underlying sterols metabolism. From a strategic perspective, we regard salt tolerant plant as an alternative to present raw materials, which will attain higher phytosterols production in combination with gene-modification.Copyright © 2020 Elsevier Masson SAS.

为探究新型海藻生物肥对草莓产量和品质的影响,以红颜草莓为试验材料,对其叶面喷施不同浓度的新型海藻生物肥,以喷施清水为对照。喷施处理后,计算草莓产量,测定盛果期草莓可溶性固形物含量、可滴定酸、糖酸比、还原糖含量、硬度、抗坏血酸、总酚、花青素和类黄酮含量。结果表明,不同浓度海藻生物肥处理的草莓产量均有提升,其中在1 500倍海藻生物肥处理下,草莓果重、结果数和产量均极显著提高(P<0.01),分别较对照增加了42.96%、14.67%和63.93%。品质结果表明,1 500倍液海藻生物肥处理下,草莓的可溶性固形物含量、糖酸比、还原糖含量和硬度均达到最大值,且较对照均显著增加(P<0.05),高于市售2种海藻肥处理;低浓度(2 500~1 500倍)海藻生物肥对草莓抗氧化物质积累有促进作用,其中1 500倍海藻生物肥处理下,草莓Vc含量达到最大值,且较对照提高50.20%;在 2 500倍海藻生物肥处理下,花青素与类黄酮含量均极显著增加(P<0.01),较对照分别增加42.00%与30.56%,而高浓度(1 000~500倍)则抑制花青素与类黄酮的积累。综上,合理喷施新型海藻生物肥能提高草莓产量,提高抗氧化活性物质含量,改善草莓品质。本研究结果为新型海藻生物肥的规模化生产应用提供了理论依据。

为研究叶面喷施海藻提取物对干旱胁迫下甘蔗叶片生理参数及植株形态指标的影响,以‘YT159’和‘ROC22’两个品种甘蔗为试验材料,采用盆栽方法,设置正常灌溉组（C）和干旱胁迫组（D）,分别通过喷施不同用量（SE1、SE2）海藻提取物,测量分析植株形态指标株高、茎径、植株鲜重以及叶片生理参数,包括水分参数、抗氧化酶活性等。结果表明：正常灌溉组喷施海藻提取物的处理（C+SE1、C+SE2）甘蔗叶片生理参数以及形态指标与不施用海藻提取物处理相比差异不显著。干旱胁迫组喷施海藻提取物（D+SE1、D+SE2）与不喷施海藻提取物的C相比,叶片脱水速率、电导率、脯氨酸含量显著降低,叶片超氧化物歧化酶（SOD）和过氧化物酶（POD）活性、相对含水量、植株鲜重显著增加,同时抗旱系数显著提高,2个品种中‘YT159’提高幅度较大,‘ROC22’提高幅度相对较小。因此,叶面喷施海藻提取物能显著改善干旱胁迫下甘蔗叶片生理参数和植株形态指标,提高植株鲜重,从而缓解干旱胁迫对甘蔗造成的伤害,提高甘蔗抗旱能力。

Loess often has poor engineering properties due to its loose accumulation and strong collapsibility. Therefore, improvement of the soil is necessary to meet the needs of engineering. In the current work, the improvement effect of sodium alginate added in different proportions to loess was studied. Limited water content test and particle size grading test were conducted to study the effect of sodium alginate on the basic physical parameters of soil. In addition, unconfined compressive strength test (UCS) and consolidated undrained test (CU) were used to analyze the changes in the mechanical properties of the soil after improvement. Additionally, permeation and disintegration tests were used to study the change in the soil's water stability. What's more, the microscopic mechanism of sodium alginate improved loess was also proposed based on the results of scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results showed that sodium alginate not only can change the liquid-plastic limit and particle size gradation of loess but also improve the strength, shear parameters, and water stability of loess. SEM and XRD studies revealed that sodium alginate changed the microstructure of the loess, formed a colloidal material to encapsulate the soil particles, filled the pores between soil particles, and caused aggregation of the clay material in the soil to form larger particle size via flocculation. These results show that sodium alginate can be used as a more environmental friendly and sustainable additive to replace the traditional soil stabilization additives, such as cement or lime to stabilize loess.

The effects of the short-term application of Ascophyllum nodosum-fermented seaweed fertilizer on the bacterial community, soil nitrogen contents, and plant growth in maize rhizosphere soil were evaluated. The changes in the bacterial community composition and nitrogen contents including those of total nitrogen (TN), nitrate nitrogen (NO-N) and ammonium nitrogen (NH-N) in rhizosphere soils in response to treatment with seaweed fertilizer were determined. Furthermore, soil enzymatic activity and crop biomass were analyzed. The relative abundance of the dominant phyla varied regularly with fertilization, and bacterial α-diversity was apparently influenced by seaweed fertilizer amendment. The TN contents of all soil samples decreased gradually, and the NO-N and NH-N contents of the soils treated with seaweed fertilizer were much higher than those of the control soils. Similarly, the enzymatic activities of dehydrogenase, nitrite reductase, urease, and cellulase in the soil were significantly increased on day 3, day 8, and day 13 after the application of seaweed fertilizer to the maize rhizosphere soil. However, there was no difference in the activity of soil sucrase between the treatment group and the control group. In this study, the growth of maize seedlings was confirmed to be greatly promoted by the utilization of seaweed fertilizer. These results deepen our understanding of plant-microbe interactions in agroecosystems and should benefit the wide use of seaweed fertilizer in sustainable agricultural production.
