Abstract

Forsythia suspensa is a good shrub for the economy and conservation of water and soil. First F.suspensa was planted successfully in Ansai in northern Shaanxi in the 1970s. then in Guyuan in Ninxia Hui Autonomous Region in the 1980s. It can be propagated by seeds

layer

cutting

divided plant etc. in the field. After F.suspensa was planted on the hills

it had a high survival rate and quick growth

Using the method of spiral afforestation

an individual can develop into a shrub in the first year

and can quicken closing and conserve soil-water content. After second year of afforestation

the shrubbery began fruit production

the erage yield of the dried fruit was 1

084.5 kg/ha; in the third and fourth year

it was 1

618.5kg/ha; in the fifth year

it was 2

670kg/ha

in seventh year

it has the highest yield of all dried fruit

about 4

000kg/ha.
