Abstract: Under the dry term in the east of Gansu, The cultivated tests on the fertilizer effect, density and different stages of Qingtian 1 were carried out. The results indicated that applying 105kg/hm2 nitrogen and 75kg/hm2 phosphorus fertilizer is the most economic and rational; applying 45000kg/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 67500 zhu/hm2, the transplanting style after growing seedlings in small arch greenhouse in early spring and the multiple cropping style after rape stubble should be extended over large areas, the multiple cropping style after wheat stubble should be extended in the southern rivers rigions of this locality.
