Taking questionnaire method in every household of a village，this paper investigated in detail
the present status of production and fertilization on seed lotus in 6 towns of Guangchang County，Jiangxi
Province．Results showed that under present production and management conditions，the average yield of seed
lotus was 1 074 kg · hm-2．The differences in yielding level of different towns were mainly related to planting
pattern and variety，while planting pattern had a bigger impact than the variety．At present，the average yields
of extensively extented‘ Taikonglian No.36’and‘Jianxuan No.17’were 1 188 kg · hm-2 and 1 007 kg · hm-2，
respectively，less than 85% of their yield potential．Disease and pest，successive cropping obstacle，irrational
fertilization，bad weather，variety degeneration and source of water were the important factors for low yield．
Aiming at the major existing problems in fertilization，technical counter measures were put forward：to use
organic fertilizer，to rationally regulate the rate of nitrogen（N），phosphorus（P）and potassium（K），to
apply alkaline fertilizer，to supplement medium，trace and beneficial element fertilizers，such as calcium，
magnesium，borax，etc.，to rationally conduct fertilizing time and method．
