山西省小麦大面积生产的突出问题,表现在产量低而不稳;特别是丘陵山区的旱地小麦,在冬季低温冻害、夏季长期干旱、后期干热风三大自然灾害面前产量更低。榆次县下丁里大队培育的夏麦一号(青春13×墨巴66)在七月上中旬播种,正当九、十月份秋高气爽,昼夜温差较大的有利时机灌浆成熟;在寒霜到来之前收获。全生育期一百天左右,能充分利

The prominent problems of wheat large-scale production in Shanxi Province are as follows: low yield and instability; especially in dry land wheat in hilly and mountainous regions, low yielding frost damage in winter, long-term drought in summer and dry-hot wind in the later period. Xiamai No. 1 (Xia 13 × Moiba 66) nurtured by the Xiadingli Brigade in Yuci County was sown in the middle of July. At the proper time of September and October, the favorable timing of large temperature difference between day and night was filling and ripening. Before the arrival of the frost reward. The whole growth period of about 100 days, can fully benefit
