不同耐旱性小麦品种产量形成适宜土壤水分的研究

STUDIES ON SUITABLE SOIL WATER CONTENT OF YIELD FORMATION IN DIFFERENT DROUGHT HARDINESS WHEAT VARIETY

在控水条件下研究了不同水分处理对不同冬小麦品种产量形成的影响。结果表明，不同耐旱性的小麦品种其经济产量和最高产量的土壤水分适宜含量不同。水浇地高产品种的适宜含量约为田间持水量的７０％，耐旱耐肥品种为６０％，耐旱耐瘠品种为５０％。

The effects of different water treatment on yield formation of different winter wheat variety in controlling water condition were reported, The results showed that the economy yield and maximum yield were different on the suitable water content of the soil in the different wheat varieties with drought hardiness. The suitable soil content of high yield variety was about 70% field moisture capacity in the irrigation field, The drought and fertilizer tolerance variety was about 60%, and the drought and barren tolerance variety was about 50%.
