在巴盟河套地区,春小麦能否就地夏播加代,以缩短育种年限,对这个问题,我们在具有塑料棚的条件下,作了探索试验。初报如下。一、气候特点与夏播小麦主要性状表现春播小麦出苗后,气温、地温逐渐上升,到成熟阶段,气温达到一年中的最高值;而夏播小麦生育期所处的气候条件与春播正好相反,播种出苗期处于高温,以后气温、地温逐渐由高到低,灌浆、成熟处于冷凉季节。
In Balenghetao area, can spring seeding increase on-site in order to shorten the breeding life, on this issue, we have a plastic shed conditions, made exploration and testing. First reported as follows. First, the climate characteristics and summer sowing wheat main characters Spring season after the emergence of wheat, the temperature and ground temperature gradually increased to mature stage, the temperature reached the highest value of the year; and summer sowing wheat growth period where the weather conditions and spring sown exactly the opposite , Sowing seedling at high temperature, after the temperature, ground temperature gradually from high to low, filling, mature in the cold season.
