Effect of Different Agronomic Measures on the Castor Production in the Caved Area of Shendong Coal Mine

[目的]研究不同农艺措施对神东矿区采煤塌陷区蓖麻产量的效应。[方法]采用L18(6×36)正交表安排正交试验,研究神东矿区采煤塌陷区不同播期、播深、种植密度、种子处理方法与蓖麻品种产量的关系。[结果]播期、播深、种植密度、种子处理方法对6个蓖麻品种产量的影响均达到极显著水平。极差分析结果表明,影响蓖麻产量因子的主次顺序为:蓖麻品种>株行距>播期>种子处理>播深。经综合对比,确定神东矿区采煤沉陷区蓖麻最佳栽培技术方案是:法国杂交种CSR24.181;播期为5月2日;种子处理为冷水浸种;播深8 cm;株行距60 cm×60 cm。在该农艺措施下,蓖麻植株生产情况较佳,产量较高。[结论]为神东矿区采煤塌陷区大面积推广种植蓖麻提供了依据。

[Objective] The different agronomic measures affecting castor production in the Caved Area of Shendong Coal Mine was studied. [Method] The relationship between the different sowing dates, the depth of seed sowed, the planting density, the method of seed treatment and the castor variety yield in the area was analyzed with the orthogonal experimental design of L18（6× 3^6） [Results] The sowing date, the depth of seed sowed, planting density and seed treatment methods was significant relationship with on the yield of six castor varieties. The analysis results showed that the order of the factor affecting the castor yield was as follow： castor varieties 〉 distance between plants 〉 sowing date 〉 seed treatment 〉 depth of seed sowed. The optimal cultivation technical measure for castor production in Shendong Coal Mine Area was： the variety ,French Hybrid CSR2A.181; the sowing date, May 2; the seed treatment, soaked with cold water; the depth of seed sowed,8 cm; and the distance between plants,60 cm × 60 cm,which could promote the better castor plant growth and higher distance between plants yield. [Conclusion] The basis of the castor plant growth in the Caved Area of Shendong Coal Mine was provided.
