摘要
以自然资源桐油为控释材料(从油桐果实中提取),生产控释肥料,进行烟草温室无土栽培盆栽试验,研究桐油控释复合肥在烤烟上的应用效果。结果表明:在温室环境条件下,桐油控释复合肥的养分初期溶出率为2.8%;施用控释复合肥的产量高出普通复合肥处理26.7 g/株;桐油控释复合肥与普通复合肥相比,每克肥料要多生产烤烟2.2 g。说明桐油控释复合肥具有很好的生产性。
The authors utilized tung oil as a coating material （from the fruits of tung oil tree） to produce controlled-release fertilizer and studied the effects of this fertilizer on flue-cured tobacco in greenhouse soil-less cultivation. The results showed that preliminary solubility rate of controlled release composite fertilizer was 2.8%; compared with common fertilizer, individual yield of flue-cured tobacco with controlled-release compound fertilizer increased by 26. 7 g and controlled-release compound fertilizer per gram produced more flue-cured tobacco by 2.2 g.
