Barley varieties were fall sown and grown in Hangzhou to study their growth and development.Following items were studied;the growth of the leaves on the main stem,tillering and the spike-forming process,the relation between panicle initiation and the number of leaves,the increase of kernel weight during the.formation of barley grain seed maturity levels and the germination percentage,the relation between the percentage of field stand and seedling vigor.Effect on the above characteristics due to differences of Varieties and sowing dates were also studied.

本试验主要研究杭州秋播条件下,大麦主茎叶片的生长,分蘖及其成穗规律,幼穗分化过程与叶数的关系,麦粒形成过程中粒重增长情况,麦粒成熟度与发芽率、田间成苗率和幼苗生长势的关系,并研究不同品种和播种期对这些特性的影响。

In 1986-1988, the main cultivars of dual ridge barley h-ave been stueied in Yellow river irrigation area of Ningxia.The laws of change trands and forming spike of cultivars (different types, ear-ly, middle and late ripe) have bccn elaborated.The fesult shows: the different cultivar of dual ridge barley qlanting in rellow River irrigati-on area of Ningxia possess the strong tillering characteristics, high fate of forming sqike and it was effected by cultivating condition, less num-ber of grains per spike, lodging frequently in the ecological condition of Ningxia. Finally, it was also qut forward there must be certain nu-mber of spike per mu in order to high yield. The cultivars of strong ti-ller abili.ty and high rate of forming ear are selected, adopting the way not only pay attention to main stem but also tiller, appropriate rare pl-anting, to qromote tillering, to increase the number of ear in ouder to achieve high yield.

1986~1988年,对宁夏引黄灌区二棱大麦主要栽培品种进行了研究,摸索出了早、中、晚三种熟期类型代表品种的分蘖变化动态及成穗规律。试验表明,引黄灌区目前种植的二棱大麦各品种在当地的生态条件下,均具有分蘖力强、成穗率高并受栽培条件影响较大、穗粒数少和易倒伏的特点。最后指出,二棱大麦欲获高产,每亩必须保证有一定的收获穗数;生产上可选用分蘖力强、成穗率高的品种,主、蘖并重,适当稀植,通过促蘖增穗途径达到高产。

The growth progress, the ;path analysis of yield component, the growth regularity of regenerating buds and high-yield ing technology of ratoon rice were investigated . T.he results showed as follow:

明确再生稻生育进程和气候生态适应性,依据热量资源的时空分布模式,提出不同纬区安全蓄养再生稻的海拔上限,及不同气候区的品种、播期布局.揭示再生稻的产量通径和腋芽成穗规律,明确促进腋芽萌发,增加再生穗数,是提高再生稻产量的关键,提出芽肥施用、水分管理,留茬高度及冷烂田垄畦栽培等丰产技术
