title: [Study of comprehensive cultivation techniques of Pinellia ternate].
abstract: OBJECTIVE
  To study the effect of N, P, K and sowing norm on yield of Pinellia ternate.
  
  
  METHODS
  The effects of N, P, K and sowing norm were studied by means of 4 factors and 3 levels orthogonal design experiments.
  
  
  CONCLUSIONS
  The effects of the 4 factors decreased in following orders is sowing norm, N, K and P. Rational amounts of fertilizer and sowing norm are 48.0-96.0 kg x hm(-2) N, 90.0 kg x hm(-2) P, 90.0 kg x hm(-2) K, 3 000.0-3 750.0 kg x hm(-2).
