Abstract
In order to coordinate with the promotion of the strong gluten wheat variety, Zhengmai 7698,the growth characteristics of Zhengmai 7698 and the relevant super-high yield cultivation technique were analyzed according to the researches in the field and experiments in small areas.The results showed as follows: Zhengmai 7698 had the automatic adjustment ability and moderate tiller; it had a long period of grain filling, and the weight of grain in filling stage increased fast, with an average of 2.1 grams of one thousand grains per day; under the condition of super-high yield, the dry matter weight of Zhengmai 7698 was mainly from the photosynthate after flowering.When the yield of Zhengmai 7698 was more than 10 500 kg/ha, the structure of its output was 6 480 000 spikes/ha, 37.5 grains per spike, and 1000-seed weight of 47.2 g; when its yield was 9 750-10 500 kg/ha,the structure of its output was 5 880 000 spikes/ha,38.1 grains per spike, and 1000-seed weight of 46.3g.The relevant cultivation techniques of super-high yield: intensive cultivation to improve the quality of field; increased fertilization of the organic fertilizer and heavy application of the base fertilizer; giving sufficient moisture and fine seeding to ensure full and uniform seedlings; and improving the regulation during the wheat growth according to the field,the seedlings and the weather.关键词
