棉花杂种优势的利用经济效益很显著,但由于制种需要人工多,成本高,限制了杂交棉的推广应用.种子产量少,一、二代的面积难以扩大,同时由于杂交种的价格较贵,生产单位不易接受.怎样能够有效地降低制种成本又提高杂交种的产量呢?1994年我们在兵团科委、石河子科委和132团领导的大力支持下立项研究,在132团场9连开展了杂交棉大面积制种,并进行了制种新技术的研究.经过科技人员及132团领导、生产科技工作人员的努力和各有关部门的全力支持,使今年的试验工作取得了较好的效果.6亩制种地收获霜前籽棉604公斤、折成杂交种毛籽398公斤.种子产量比1993年提高了7.9倍.而每公斤杂交种的制种成本则由93年的250元降至今年的17.78元,降低了232.22元,在今年的制种中我们主要进行了以下研究并采取了如下几项措施:1、积极组织技术培训,认真推行制种人员的承包责任制
The utilization of cotton heterosis has obvious economic benefits, but due to the need of artificial production and high cost, the application of hybrid cotton is limited, and the area of one or two generations is difficult to expand due to less seed yield and the price of hybrid is more expensive , The production unit is not easy to accept.How can we effectively reduce the cost of seed production and increase the yield of hybrid seed? In 1994 we Corps Science and Technology Commission, Shihezi Science and Technology Commission and 132 regiment leaders with the strong support of the project research, A large-scale hybrid cotton seed production was carried out and new techniques of seed production were studied.After the efforts of scientific and technical personnel and the leaders of 132 groups, the production and technical staff and the full support of all relevant departments, the experimental work of this year has been made better Of the effect.6 acres of land to harvest frost before the first seed cotton 604 kg, converted into hybrid seed Mao 398 kg seed yield increased 7.9 times than in 1993. And seed production cost per kilogram of hybrid from 93 in 250 yuan Down to this year’s 17.78 yuan, a decrease of 232.22 yuan, in this year’s seed production we mainly conducted the following research and taken the following measures: 1, actively organize technical training, conscientiously implement the contractor responsibility System
