对1997—2000的区试试验和品种比较试验结果进行统计分析,结果表明小麦品种洛旱2号丰产性好,稳产性突出,抗旱性明显优于对照豫麦2号,是一个产量高而稳、抗旱性突出的旱地小麦新品种。通过对不同产量水平下的产量结构进行分析,得出洛旱2号的产量构成最佳模式为:公顷穗数525—600万/hm~2,穗粒数30—32粒,千粒重37—40克。对其产量构成要素与产量的通径分析表明:洛旱2号的高产栽培技术途径是在保证足够穗数的基础上,提高小穗结实率,增加穗粒数,稳定千粒重,充分发挥其丰产性。
The results of field test and variety comparison test from 1997 to 2000 were statistically analyzed. The results showed that the wheat cultivar Luohan 2 had good yield and stable yield, drought resistance was significantly better than that of Yumai 2, which was a high yield and stable , Drought-resistant new varieties of dry land wheat. Through the analysis of the yield structure under different yield levels, we can conclude that the best mode of production of Luohan 2 is: the number of spikes per hectare is 525-600 million / hm ~ 2, the number of spikelets is 30-32 and the grain weight is 37-40 G The path analysis of yield components and yield showed that the high-yield cultivation techniques of No.2 LA were to increase the spikelet seed setting rate, increase the number of spikelets, stabilize the 1000-grain weight and give full play to its high yield Sex.
