[ ] habitat distribution
Ecological environment : in road and cottage nearby.
Resource distribution: widely cultivated throughout the country.
Cultivated [ ]
Biological characteristics of tropical tree species, in the the Yellow River basin, the lower reaches of the Yangtze River, growth is good. Likes the warm, sunny. Soil with deep, loose, fertile, well drained loam best. Ability to drought, salt resistance, alkali resistance.
Cultivation techniques of seed propagation can be generally used, with points, root and cutting propagation.
Field management of locust for shallow root tree, gale after each easy rock roots, so should pay attention with the soil pressure of rhizosphere, in order to avoid dumping.
Pest control four Limacodidae damage leaf; spot coat wax cicada damage cadre, it is the application of Isoprocarb prevention; longicorn beetle also damage cadres.
