摘要
通过小区试验,研究了施肥对红花生长的影响。结果表明,尿素450 kg/hm2、三料磷肥375 kg/hm2处理对促进红花的株高和分枝效果最好,最终株高为70.85 cm,一级分枝数为12.53,二级分枝数为23.93;施尿素225 kg/hm2、三料磷肥375 kg/hm2、硫酸钾150 kg/hm2处理红花花绒产量最高,产量为400.00 kg/hm2,比对照增产37.08%;尿素450 kg/hm2、三料磷肥187.5 kg/hm2、硫酸钾150 kg/hm2处理红花籽粒产量最高,产量为3 822.50 kg/hm2,比对照增产107.16%。在中等肥力条件下,推荐最经济施肥量为尿素450 kg/hm2,三料磷肥187.5 kg/hm2,硫酸钾肥150 kg/hm2。
The paper studied effect of fertilization on the growth and yield of Carthamus tinctorius L.by plot test.The results showed that plant height and branch number were optimization at N fertilizer 450 kg/hm2 and P fertilizer 375 kg/hm2,plant height was 70.85 cm,first branch numbers of plant were 12.53,second branch numbers of plant were 23.93;The yield of Carthamus tinctorius L.was 400.00 kg/hm2 at N fertilizer 225 kg/hm2,P fertilizer 375 kg/hm2,and K fertilizer 150 kg/hm2 and increased by 37.08% compared with CK;The maximum yield of Carthamus tinctorius L.seed was 3 822.5 kg/hm2 at N fertilizer 450 kg/hm2,P fertilizer 187.5 kg/hm2 and K fertilizer 150 kg/hm2 and increased by 107.16% compared with CK;Under the middle fertilizer status in soil,the optimum economical application of fertilization is N fertilizer 450 kg/hm2,P fertilizer 187.5 kg/hm2 and K fertilizer 150 kg/hm2.
