抗倒伏问题对于谷子的重要性谷子是传统的旱粮作物,耐旱耐瘠;谷草又是优质饲料,要求质地柔软。但随着水肥条件不断提高,在高产栽培条件下,前期容易生长繁茂,穗大花多,灌浆后极易倒伏,空粃粒增加,产量不能相应提高。为此,迫切需要解决这一矛盾。谷子倒伏有两种情况,一为基部秆软,平铺瘫倒,一为上部曲折倾倒,均有株型结构上的弱点。以往获得“千斤谷”的经验都需要采取蹲苗培土等促控措施。但条件千变万化,所取措施不能确保奏效。因而,选育抗倒伏品种已成为关系到谷子在生产上的地位和发展远景的紧迫任务。
The importance of lodging resistance to millet Millet is a traditional drought-tolerant barren grain, which is a good quality feed and requires soft texture. However, with the continuous improvement of water and fertilizer conditions, under the conditions of high yielding cultivation, the early stage is easy to grow and flourish, spike large flowers, easy to lodging after grouting, empty noodles increase, the yield can not be increased accordingly. Therefore, there is an urgent need to resolve this contradiction. There are two cases of millet lodging, one for the base of stalks, collapsed flat, one for the upper part of the twists and turns, both plant-type structure of the weaknesses. In the past access to “jack kiln” experience needs to take the Dunmiao soil and other control measures. However, the ever-changing conditions can not ensure effective measures. Therefore, the breeding of lodging resistant varieties has become an urgent task related to the production status and development prospects of millet.
