摘要

In Line with the promotion of Zheng-wheat 7698 with strong gluten, this article analyzed the growth of Zheng-wheat 7698 and the relevant super-high yield cultivation technique according to the researChes in the field and experiments in small areas. The results show as follow: under the super-high yield condition, Zheng-wheat 7698 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, the leaves of Zhegn-wheat 7698 stuck out and had good Light transmittance, and the top-three leaves had long functional period, under the super-high yield condition, the index of the leaf area came to 7.63, the index of the top-three leaves was 5.01 and the index of the flag leaf was 1.69, the dry matter weight of Zheng-wheat 7698 was mainly from the photosynthate after flowering, Zheng-wheat 7698 £¾10500kg/ hm2, the structure of its output was 6480000 spikes / hm2, 37.5 grains per spike, and one tHousand grains' weight was 47.2g; 9750∼10485kg/ hm2, the structure of its output was 5880000 spikes / hm2, 38.1 grains per spike, and one tHousand grains' weight was 46.6g.
