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.

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

The changes of cultivated area and yield of main food crops, fruit trees, vegetables and cash crops in Jianshi county between 1956, 1981 and 2014 were analyzed. It was found that Jianshi county was rich in natural resources, and the local varieties of rice, wheat and rape reduced rapidly, and some local varieties even have nearly disappeared, but the other kinds of crops still preserved some local varieties and some minor crops were planted mainly with local varieties. The total planting area of food crops changed a little in these three investigations, and corn is the most important food crop in Jianshi all the time. The planting area of fruit trees and main cash crops increased rapidly, but the planting area of vegetables decreased seriously. 44 local resources were collected in the resource investigation. According to the abundant resources of Jianshi county, the weak agricultural infrastructure construction, and the low element of agricultural science and technology, some countermeasures were proposed, such as strengthening the protection and utilization of existing crop resources, accelerating the cultivation of new agricultural varieties and the extension and training of new technologies, strengthening agricultural technology service accelerating the construction of modern agricultural industrialization, increasing government support and propagation.
