1971—1979年的高产栽培研究和因子试验结果说明:(1)穗粒重与产量之间有极显著的正相关,高产田应侧重于改善个体的发育条件,提高单穗生产力,文中以经验公式为依据,讨论了适宜的穗数范围。(2)穗粒数与每穗粒重之间存在极显著的正相关,千粒重与每穗粒重间仅表现一定的正向关系,说明在目前栽培条件下,通过增加每穗粒数的途径提高穗粒重尚有较大的潜力。(3)粒重既是相对稳定的,又与环境条件有密切联系。所以,必须选用产量性状优良的品种,栽培措施应保证品种生产潜力的充分发挥。
The results of high yield cultivation studies and factor experiments from 1971 to 1979 showed that: (1) There was a significant positive correlation between grain weight and grain yield, high yielding fields should focus on improving individuals’ developmental conditions and improving single ear productivity. Formula based on the discussion of the appropriate range of spikes. (2) There was a significant positive correlation between the number of grains per spike and the grain weight per spike. The relationship between grain weight and grain weight per spike showed only a positive correlation, indicating that under the current cultivation conditions, There is still great potential for increasing grain weight. (3) grain weight is relatively stable, but also with the environmental conditions are closely linked. Therefore, we must choose varieties with good yield traits, cultivation measures should ensure that the full potential of varieties of production.
