食用菌产业集群升级的路径与保障措施

食用菌产业具有生产集约化、作业标准化、产业绿色化的显著特点。目前,我国食用菌产业集群初步成型,但区域差异较大。虽然产品类型丰富,但技术水平偏低,且与美国相比,价值链的延伸还较为不够。因此,既要进一步推动产业补链、强链,加强科技创新赋能,打造特色产业品牌,形成共享协同机制,从而助推食用菌产业集群升级；又要强化产业政策引领,完善行业管理标准,重视优秀人才引育,从而夯实食用菌产业集群升级保障。

Use of Industrial By-products to Sorb and Retain Phosphorus

The potential of six industrial by-products for use as phosphorus-sorbing materials (PSMs) in solutions was evaluated. These included two different acid mine drainage treatment residuals (AMDR1 and AMDR2), water treatment residual (WTR), fly ash, bauxite mining residual, and flue gas desulfurization product (FGD). Characterization of the by-products and their mechanisms for sorption and retention of inorganic phosphorus (P) from solution identified those PSMs that sorbed primarily by an iron and aluminum (Fe/Al) mechanism, those that sorbed primarily by a calcium and magnesium (Ca/Mg) mechanism, and those that sorbed by both mechanisms. Degree of P sorption and associated mechanisms were strongly influenced by the pH, buffer capacity, ionic strength, and common ion effects.

How to communicate soil expertise more effectively in the information age when aiming at the UN Sustainable Development Goals

Soil use and management play a key role, when maintaining or restoring soil quality, as an estimated 30% of soils in the world suffer from various forms of degradation. Several of the seventeen UN Sustainable Development Goals (SDGs), approved in 2015 by 195 governments, are land‐related, providing a stimulating challenge for soil research. Unfortunately, soil degradation is still prominent, even though decades of research have resulted in restorative and innovative forms of soil management, generating successful case studies all over the world. Why don't enough farmers adopt such research results? Some argue that the problem of soil degradation is mainly socio‐economic rather than technical. However, this is not correct as the soil–water–plant–climate system raises many basic, unresolved questions about soil behaviour. More attention is needed for information sharing and knowledge building to link the research arena with stakeholders and policy makers. This is particularly urgent because the information revolution, which is fundamentally changing attitudes of increasingly critical stakeholders, presents a challenge to distinguish between relevant and irrelevant information on Internet and social media. Continuous interaction with land users in the field and sharing knowledge in a joint‐learning mode is needed more than ever, recognizing that different forms of knowledge can contribute to acceptance in the practice of land‐use innovations and lead to realization of land‐related SDGs. Such forms of interaction take much time, which is of limited availability in current research regimes, and implies a need for change. Soil scientists need assistance from communication experts to facilitate interaction processes.     

Evaluation of valuable nutrients in selected genotypes of marula (Sclerocarya birrea ssp. caffra)

Different marula clones domesticated in the arid Negev desert were evaluated for their horticultural behavior physiological and antioxidant characteristics of their fruits. Two types of abscission pattern were detected, early and late. Fruit yields fluctuated from year to year (6–45 kg/tree) with large differences between clones (few fruits to 45 kg/tree). The clones also differed in fruit weight (34.41 ± 0.91 to 56.74 ± 1.65 g), shape, and juice content. Ascorbic acid content was found to be high in all the clones with significant differences among clones and time post-abscission. Clone no 12 at 1 week post-abscission had the higher ascorbic acid content, 21.177 mg/g dry weight and clone no 4 at the abscission day had the lower ascorbic acid content, 7.142 mg ascorbic acid/g dry weight. The total antioxidant and polyphenol content of the juice varied among clones and with time post-abscission, as did the activity of superoxide dismutase (about 1.40 IU/g dry weight of SOD at week 0 for all clones, to 2.67 IU/g dry weight at the third week post-abscission). Fresh marula juice had, on average, four times more antioxidant than the juice of either orange or pomegranate (marula ascorbic acid equivalent: 8.52 ± 0.76 mM to 23.26 ± 2.20 mM versus 2.72 ± 0.39 mM to 7.38 ± 0.18 mM and 2.56 ± 0.41 mM to 3.92 ± 0.18 mM, respectively), considered to be rich in antioxidants. Marula ice cream and jam manufactured according to industrial protocols were rich in ascorbic acid 45 days post-production. In conclusion, selected genotypes of marula exhibited superior horticultural traits and high antioxidant contents. These data should be of value in selecting marula clones for commercial planting.
