杂交高粱在南方推广以来,再生栽培引起了广泛的重视。据各地试验,一致肯定再生高粱具有省工、省种、早熟、高产等优点,是多次利用杂种优势的有效途径。尤其在南方,通过再生栽培,一年可以三熟,为夺取多熟高产创造了有利条件。但是,当前再生高粱栽培也存在一些问题,如出苗不齐、缺株断垅等,都要进一步研究解决。
Since the popularization of hybrid sorghum in the south, regenerative cultivation has aroused widespread attention. According to the tests all over the world, it is unanimously affirmed that regenerated sorghum has the advantages of provincial workers, provincial species, early maturing and high yield, which is an effective way to utilize heterosis repeatedly. Especially in the south, through the cultivation of regeneration, three crops can be cooked in one year, creating favorable conditions for seizing more and more high-yield crops. However, there are still some problems in the current regenerated sorghum cultivation, such as the emergence of missing seedlings, lack of strains, etc., which should be further studied and solved.
