The rueslt showed that, there were 12 suitable rice varieties. Viewing from the main body of variety breeding, the varieties mainly selected by enterprises;Quanyou series of high quality hybrid combinations generally had large grains per panicle and high seed setting rate, but the effective panicle number was general, and the yield per panicle contributed more in unit yield. Quanyou series of high quality hybrid combinations could be selected and bred varieties with good rice quality and blast resistance, but breeding varieties resistant to bacterial blight and brown planthopper remained to be strengthened.

GC-MS was used to analyze the volatile components of the herb pair, and then the potential targets of the active components were predicted through the TCMSP database and the Swiss Target Prediction database; inflammation-related gene targets were got through TTD database and GeneCards database; Cytoscape 3.7.2 software was used to construct a drugs-components-targets network diagram; string database and Cytoscape 3.7.2 software were adopted to build a target PPI network, then screening out key targets; the Clsuter Profiler program package in R 3.6.1 software was used to perform gene ontology （GO） function enrichment and KEGG pathway enrichment analysis for potential targets. The results showed that 35 kinds of volatile components were identified from the herb pair, accounting for 70.53% of the total volatile components. From the screening, 33 active compounds, 35 key targets, 1 296 biological processes, and 155 signal pathways were obtained. According to the prediction of network pharmacology results, the herb pair may regulate lipids and atherosclerosis, human cytomegalovirus infection, IL-17 and other signaling pathways through active ingredients such as β-caryophyllene, α-humulene, and α-pinene, and key targets such as TNF-, IL-6, and IL-1B, thereby synergistically exerting anti-inflammatory effects.

From 2006 to 2018, the annual average value of NDVI in Yunnan Province was 0.641, and the average annual growth rate was 0.002 26/10 years; among the NDVI values of the four seasons, only the summer showed a negative correlation trend, and the fluctuation range was obvious. Among the monthly average values of NDVI in 13a, NDVI reached the lowest in June and July. The results of the analysis of NDVI, DEM and meteorological factors showed that the proportion of NDVI was the largest at <3 000 m, which is 91.51%, and the vegetation coverage in this area was the best; the proportion of NDVI was the largest in the 10°~15° region, and with the increase of slope, NDVI first increases and then decreases. The proportion of NDVI was the largest in the north slope, and the proportion of other slopes was basically the same, and the vegetation growth state was good. The correlation between NDVI and air temperature was better in altitude, and NDVI was mainly affected by precipitation in terms of slope and aspect. Reference | Related Articles | Metrics
