为了筛选一批适于小量播种的品种,并确定其适宜播量,2001～2003年,以13个品种为材料进行了小量播种试验。试验结果表明,在参试品种中,DS1号、临抗1号、冀麦30、鲁麦21和京411适于小量播种。适宜播种量为22.5kg/hm2。试验中,这些品种生长发育正常,有较强的单株分蘖能力,主茎和大分蘖的穗分化能同步完成,均具有较高的单株穗数。在22.5kg/hm2播量条件下,5个品种的产量为6652.5～8537.7kg/hm2。在2002～2003试验年度中,京411、鲁麦21、临抗1号、DS1号的最高产量分别达到10005.0、8704.35、7553.85、7503.75kg/hm2。在高产的基础上,一些品质性状表现也较好。
In order to screen a number of varieties suitable for small sowing, and to determine the suitable sowing amount, a small quantity sowing experiment was conducted with 13 varieties from 2001 to 2003. The results showed that DS1, Linyi 1, Ji-mai 30, Lumai 21 and Jing-411 were suitable for small-scale sowing. Suitable sowing capacity of 22.5kg / hm2. In the experiment, these varieties had normal growth and development, strong tillering ability per plant and spike differentiation of main stem and big tiller simultaneously, both of them had higher number of ears per plant. Under 22.5kg / hm2 sowing conditions, the yield of 5 varieties was 6652.5 ~ 8537.7kg / hm2. During the 2002-2003 pilot year, the highest yields of Beijing 411, Lumai 21, Linqiang 1 and DS1 reached 10005.0, 8704.35, 7553.85 and 7503.75 kg / hm2, respectively. On the basis of high yield, some quality traits also performed well.
