- Abstract:
- In this paper, the purposes of returning farmland to forest construction of ecoeconomy and trees, jujube+grapemixed mode, Taiwan jujube+mango mixed mode and jujube monoculture in dry hot valleys of the Jinsha River under the conditions of the same site are to control soil erosion through land conversion effectively, improve the ecological environment, change the structure of soil, increase soil fertility, increase farmers income, solve the problem of farmers life. Three typical afforestation modes (i.e., pure jujube grove mode, jujube mixed with grape grove mode, muaritiana mixed with mango grove mode) were established by planting four economic and ecological tree species. The results showed that all the three cropping patterns had the high economic benefits, among which jujube mixed with grape grove mode was the best mode with respect to not only its output per unit area, net income, economic output ratio, as well as land productivity. The output value and net income obtained from jujube mixed with grape grove mode were 2.6 and 2.7 times as same as the other two modes; and its economic output ratio, land productivity are 1.2 and 2.6-fold than the other modes. The mode sequence according to their economic contribution was as following: jujube mixed with grape grove mode, mauritiana mixed with mango grove mode, pure jujube grove. Biomass of this mode and its related indicators were higher than the other two ones, though each mode played some regulatory role in the local microclimate. In the muaritiana mixed with mango grove mode, grove inside temperature was lower 11.8 than outside one, which was 1.62 times and 1.21 times, respectively, as same as the other ones. However, the decline of grove 5 cm surface temperature was most obvious under jujube mixed with grape grove, which was also the best mode in view of the effects of soil improvement. The suggestion regarding the economic combined with ecological benefits was put forward as the suitable mixed cropping pattern was jujube mixed with grape grove mode or muaritiana mixed with mango grove mode.
