锦花杂种优势利用是一项增加产量、改进品质的新措施。在今年一月召开的第三次全国棉花科学研究工作会议上,根据我国人民公社的生产潜力和科学研究成果,明确了在我国具体条件下,利用杂种优势增产棉花的重要性和可能性。生产一亩棉田点播用的杂交种子,约需三个工,而利用这样的种子一般可增产约20%上下。今年有不少研究所和试验站的丰产田已经采用了杂交第一代的种子。河北省棉花研究所在三月间召开的棉花研究设计会议上,确定今年在省内各专区农科所、站组织重点人民公社生产十万斤杂交种子,供明年示范用。这是提高棉花品种工作的一个新的途径,是值得引起重视的。
Jinhua heterosis utilization is a new measure to increase output and improve quality. At the Third National Conference of Cotton Scientific Research held in January this year, according to the productive potential of our people’s communes and scientific research achievements, we have clarified the importance and possibility of using heterosis to increase cotton production under our country’s specific conditions. Production of an acre of cotton seed used in hybrid seeds, about three workers, and the use of such seeds can generally increase about 20% from top to bottom. Many high-yielding fields at research institutes and experimental stations have adopted the first generation of hybrid seeds this year. Cotton Research Institute of Hebei Province in March held a cotton research design meeting, this year in the prefecture in the province identified agricultural stations, stations and key people’s communes to produce 100,000 kilograms of hybrid seed for demonstration next year. This is a new way to enhance the work of cotton varieties and deserves our attention.
