“…Germination force (GF), germination percentage (GP), and germination index (GI) were calculated according to the following equation (Wang et al., 2019):

GF (%) = Number of germinated seeds in first one - third of evaluation days / Total number of Seeds \times 100

GP (%) = false(N_{1} + N_{2} + N_{3} \dots + N_{n ‐ 1} + N_{n} false) / Total number of Seeds \times 100

GI = (N_{1}) / 1 + (N_{2}) / 2 + (N_{3}) / 3 + \dots + (N_{n ‐ 1}) / (n ‐ 1) + (N_{n}) / n

where N 1 , N 2 , N 3 ,…, N n : the number of germinated seeds in the first, second, and final counts, and 1, 2,…, n was the first, second, and final evaluation days.…”

Elymus nutans has been widely planted together with other perennial grasses for rebuilding degraded alpine meadow atop the Qinghai‐Tibetan Plateau. However, the rebuilt sown pastures begin to decline a few years after establishing. One of the possible causes for the degradation of sown grassland may come from allelopathy of planted grasses. The purpose of this study was to examine allelopathic potential of Elymus nutans. Three types of aqueous extract from Elymus nutans and its root zone soil were prepared, and 5 highland crops and 5 perennial grasses were used as recipient plants. Elymus nutans exhibited strong allelopathic potential on germination and seedling growth of 5 crops, but different crops or perennial grasses respond to the extract differently. The pieces aqueous extract have stronger inhibition than whole plant extract and root zone soil extract. Hordeum vulgar var. nudum, Avena sativa, and Festuca sinensis were the most affected, while Chenopodium quinoa and Elymus sibiricus were the least affected. Elymus nutans presented less influence on Poa pratensis and Poa crymophylla than on Festuca sinensis. It is recommended that the species combination of mixture for restoration should be considered for allopathic effects on the coseeding to decrease the seeding rate ratio of Elymus nutans. The annual dicot crop seeds of Chenopodium quinoa and Brassica napus can be used as alternative subsequent crop for the seed field of Elymus nutans monoculture.

Drooping wildryegrass (Elymus nutans) has been widely planted together with other perennial grasses for rebuilding degraded alpine meadow atop the Tibetan Plateau. However, the rebuilt sown pastures begin to decline a few years after establishing. One of the possible causes for degradation of sown grassland may come from allelopathy of planted grasses. The purpose of this study was to examine allelopathic potential of drooping wildryegrass. Three types aqueous extracts from drooping wildryegrass and its root zone soil were prepared and 5 highland crops and 5 perennial grasses were used as recipient plants. Drooping wildryegrass exhibited strong allelopathic potential on germination and seedling growth of 5 crops germination and growth, but different crops or perennial grasses respond to the extracts differently. The pieces extract has stronger inhibition than others. Hulless barley, oat and Chinese fescue were the most affected, while quinoa and Siberian wildryegrass were the least affected. Drooping wildryegrass presented less influence on Kentucky bluegrass and crymophylla bluegrass than on Chinese fescue. It is recommended that the species combination of mixture for restoration should consider allopathic effects of the co-seeding and decrease the seeding rate ratio of drooping wildryegrass. The annual dicot crop quinoa and rape seeds can be used as alternative subsequent crop for seed field of drooping wildryegrass monoculture.

“…After cultivation, the length (distance from the leaf base to the leaf tip) of the leaf, fresh weight and dry weight (105 ℃ for 2 hours, and 60 ℃ until constant weight) of the shoot were measured (Hao et al, 2018). The chlorophyll contents of the plants were determined using a spectrophotometer after 24 hours of extraction of the cut leaf using 95% ethanol (Wang et al, 2019). Referring to NIST SRM 2711a Li, J. et al, 2014), total digestion was carried out on ball-milled plant samples by using concentrated HNO 3 /HClO 4 (4:1) on a hot plate, and then the elemental concentrations in the ltrates were analysed.…”

“…Metals are adsorbed by roots and transported in the form of metal complexes or free metals across the root cortex to the stele (Niu et al, 2011;Zhao et al, 2018). Their translocation from RPFs to plants eventually causes them to accumulate through food chains, posing a risk to the health of animals and humans (Li, Z. et al, 2014;Yu et al, 2012;Zhao et al, 2018). However, the pros of applying RPFs far outweigh their cons.…”

“…In addition, some RPFs, such as biochar, enhance the water retention effect of soil, mitigate metal pollution, adjust the pH of the soil, etc. (Steinbeiss et al, 2009;Wang et al, 2019). As such, it is di cult to determine the effect of RPFs only through the existing accepted criteria due to their complexity (Kratz et al, 2019;Meena et al, 2019).…”

Phosphorus (P) recovery from incinerated sewage sludge ash (ISSA) has been extensively investigated, and various recovered phosphate fertilizers (RPFs) have been produced. In this study, three RPFs (calcium phosphate compounds (CaP), struvite (SP), and P-loaded biochar (BP)) produced from ISSA were characterized and their agronomic effectiveness were verified by pot experiments with the cultivation of choy sum (Brassica campestris L. ssp. Chinensis var. utillis Tsen et Lee) and ryegrass (Lolium perenne L.). The SP has the highest P purity while the BP has the most complex P species. And the plant growth results showed that the RPFs greatly facilitated plant growth and demonstrated superior/comparable effects to those of MP/CoF. In general, choy sum fertilized with SP showed the best effect due to the Mg involved and the high P purity of SP, while ryegrass fertilized with BP performed the best among all of the groups because of the additional nutritional elements and the high P availability of BP. Additionally, the accumulation of heavy metals in the plants under all conditions did not exceed the limits stipulated in the regulations. These results indicate that recovering P from ISSA is an attractive technology to produce P fertilizers, which can alleviate both the scarcity of phosphate resources and the burden of ISSA management.
