决明子种植密度研究

Research on the Planting Density of Semen Cassiae

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1hm2分别增产700.5、409.5、430.5、736.5kg。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1hm2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。

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/bin2 was very significantly higher than the other four kinds of planting density of grain yield. Planting density of 97 500 cassias/bin2 and 142 500 cassias/hm2 grain yield were significantly higher than the planting density of 75 000 cassias/hm; 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 hm; respectively. The economic benefit of density of 120 000 cassias/hm2 was the highest,respectively than the other four planting density per hm2 increased by 7 005,4 095,4 305,7 365 yuan. Comprehensive consideration, the optimum planting density of Semen Cassiae was 120 000 cassias/hm2.
