摘要：

为了给粒子流在生产中应用提供理论依据，研究粒子流处理对旱地小麦产量及其发芽等效应，选用‘长旱58’和‘晋麦47’2个旱地主栽品种，在不同浓度的粒子流能量场处理后进行室内发芽试验和2个点（长武和合阳）小区试验。结果表明：粒子流能量场处理能提高种子的发芽势1.0%~2.67%，发芽率1.12%~4.82%。同时对苗期生物学性状有显著的效应，粒子流能量场处理发芽15天后，2个品种种子根条数存在较大差异，‘长旱58’的比对照减少5.8%~7.1%，而‘晋麦47’比对照增加1.3%~7.8%；粒子流能量场处理在一定程度上可以促进种子根的伸长生长，品种间的差异极显著；单株生物量均呈降低趋势；对株高的影响并不显著。粒子流能量场处理后可以提高小麦籽粒产量，以120W/h/kg处理产量最高，‘长旱58’比对照增产5.3%，‘晋麦47’比对照增产6.2%。对产量结构的效应品种之间存在较大差异。不同处理还可以提高开花期旗叶光和速率。

Abstract:

The Granular Flows effects of the wheat on yield and germinating was studied in order to better use the Granular Flows technology at farm. The two main cultivars for dry land, ‘Changhan 58’ and ‘Jinmai 47’, treated by different dosages of granular flows, had been experimented by indoor germinative test and plot tests in Changwu and Heyang. The results indicated that, the rate of the experimental germinability increased 1.0%-2.6% comparing the none-experimental samples, and the rate of germinating capacity increased 1.12%-4.82%. It also showed significant changes on its biological character at the seedling stage. There was significant difference of the root numbers between the experimental seeds and contrast seeds after 15 days of germinating. The experiments were 5.8%-7.1% decrease than the none-experiments for ‘Changhan 58’, and more than 1.3%-7.8% for ‘Jinmai 47’. The results indicated that, the granular flows helped the roots develop much faster and stronger although there was obvious difference among the variety of seeds. The average biomass was decreased and no significant difference of the stem length comparing the contrasts. Higher grain yield had been observed through the treatment by granular flows. The treatment of 120 W/h/kg group was the best. The treatment of 120 W/h/kg grains of ‘Changhan 58’ and ‘Jinmai 47’ increased 5.3% and 6.2% respectively than the control groups. There was obvious difference of effects on yield component among the two wheat varieties. Different dosages of granular flows would increase the photosynthetic rate of flag leaves during anthesis.
