- 摘要:
- 以市售决明子为试材，采用随机区组设计，研究了5种种植密度对决明子籽粒产量、经济性状和经济效益的影响。结果表明：种植密度为120 000 株/hm2的籽粒产量极显著高于其它4种种植密度的籽粒产量；97 500、142 500株/hm2的籽粒产量显著高于75 000、165 000株/hm2种植密度的籽粒产量。种植密度120 000/hm2的籽粒产量比其它4种密度1 hm2分别增产700.5、409.5、430.5、736.5 kg。种植密度120 000株/hm2的经济效益最高，分别比其它4种种植密度1 hm2增效7 005、4 095、4 305、7 365元。综合考虑,决明子的最适种植密度为120 000株/hm2。
- Abstract:
- Taking Semen Cassiae as material,using randomized block design,the effect of 5 planting density of Semen Cassiae on the grain yield,economic characters,economic benefit of it was studied.The results showed that grain yield with planting density of 120 000 cassias/hm2 was very significantly higher than the other four kinds of planting density of grain yield.Planting density of 97 500 cassias/hm2 and 142 500 cassias/hm2 grain yield were significantly higher than the planting density of 75 000 cassias/hm2 and 165 000 cassias/hm2.Among them,the grain yield of planting density of 120 000 cassias/hm2 increased by 700.5,409.5,430.5,736.5 kg than the other four density per hm2 respectively.The economic benefit of density of 120 000 cassias/hm2was the highest,respectively than the other four planting density per hm2increased by 7 005,4 095,4 305,7 365 yuan.Comprehensive consideration,the optimum planting density of Semen Cassiae was 120 000 cassias/hm2
