在石河子地区生态条件下,对6个不同类型的冬小麦品种(系)主茎叶数与分蘖成穗规律进行了2—3年系统研究,结果表明,弱冬性小麦主茎叶数少于冬性、强冬性的品种。播期不同,主茎对数随播期推迟而减少;多数品种的有效办蘖叶龄期是从主茎第4叶到第7叶的4个叶龄期。多数冬小麦品种的生理技节叶龄期为主茎第9、10两个叶龄;在适期播种条件下,除主茎穗外,尚有鞘蘖、1N.2N、3N、4N、2N-1和1N-2等蘖位的分蘖有成穗的潜力。因此,生产上可利用低位蘖成穗。
Under the ecological conditions in Shihezi region, the main stem number and tillering law of 6 different types of winter wheat cultivars (lines) were studied systematically for 2 to 3 years. The results showed that the number of main stems of weak winter wheat was less than that of winter Sexual, strong winter varieties. Different sowing date, logarithm of main stem decreased with the sowing date delayed; the effective tillers age of most varieties was 4 leaf age from the 4th to the 7th leaves of the main stem. Physiological techniques of most winter wheat varieties showed that the leaf age was the 9th and 10th leaf age of the main stem. Under appropriate sowing conditions, except for the main stem spike, there was sheath-tiller and 1N. Tillers with 2N, 3N, 4N, 2N-1 and 1N-2 tillers have the potential for panicle formation. Therefore, the production of low tillers can be made into spikes.
