Abstract:
      The tests of the fertilizer effect,density and different growth stages of Qingtian 1 were carried out.The results indicated that applying 105 kg/hm2 nitrogen and 75 kg/hm2 phosphorus fertilizer is the most economic and rational method;applying 45 000 kg/hm2 farm manure with phosphorus as base fertilizer, two thirds nitrogen as seed manure and one third nitrogen as topdressing is more economic and rational;the best planting density is 67 500 plant/hm2;the transplanting style after growing seedlings in small arch greenhouse in early spring and the multiple cropping style after rape harvesting should be extended over large areas;the multiple cropping style after wheat harvesting should be extended in the southern rivers rigions of this locality.
