鸡冠花变种、退化一直是栽培中难以解决的问题。特别是大头鸡冠花品种经常出现分枝、头小、冠少、头歪等现象。过去人们总认为是种子杂交等原因造成的,因此必须防止不同品种鸡冠花杂交,且要选留植株中上部的种子,但尽管如此,退化仍不能完全避免。我们在生产中发现:一个人留的种子,不同人栽培,退化程度不同,有的似乎完全变种。故又收集不同人栽培的鸡冠花中上部的种子,由某一个人播种栽培,则差别不明显。由此我们认为除选留好种外,改善栽培条件,加强肥水管理,增强阳光照射,有利于保持优良性状。具体表现在以下几个方面。
Cockscomb variety, degradation has been difficult to solve the problem of cultivation. In particular, the bulk of cockscomb varieties often appear branching, head small, crown less, head crooked and so on. In the past, people always thought of as hybridization of seeds and other reasons. Therefore, it is necessary to prevent crossbreeding of different cultivars and to choose the upper seeds in the plants. However, degradation can not be completely avoided. We found in production: a person to stay in the seeds, different people cultivation, different degrees of degradation, and some seem to be completely different varieties. It is also collected from different people cultivated celosia in the upper part of the seeds, sown by a certain individual cultivation, the difference is not obvious. Therefore, we believe that in addition to selecting good species, improving cultivation conditions, strengthening fertilizer and water management, and enhancing sun exposure are good for maintaining good traits. Specific performance in the following areas.
