摘要
在陇东旱地冬小麦上进行了4种增产剂3种应用方法的试验和示范。结果表明,天达2116浸种、叶喷 和浸喷复合处理效果最好,较对照增产9．2％～30．9％,增产原因是促进了小麦分蘖和抽穗,增强了抗早性, 减轻了锈病危害,显著增加了有效穗数、穗粒数和千粒重。迦姆丰收浸种和叶喷效果次之,较对照增产10．3％ ～17．0％;KH2PO4和动力2003浸种效果较好,较对照分别增产18．5％和32．1％。
Demonstration and test with four types plant cytolemma regulators and three application methods in dryland winter wheat were carried out in the east of Gansu province.

The reasons is improved tiller and heading, boot up the drought resistance of,reduced stripe rust, increased valid ears and grains and thousand grain weight. The effect of Jamu-bumper soaked seed and sprayed are second, it increased yield of 10.3%-17.0% as compared with CK. The effect of dongli-2003 and KH2PO4 soaked seed are third, it increased yield of 18.5% and 32.1% as compared with CK.
