This paper, through the special research of measure experiment related to the high quality weak tendon wheat Ning Wheat No.9 that popularized for my city, and on the foundation of the group quality cultural technology of original maturation, rounding the special quality requirement of biscuit wheat, the cultural effect that affecting output and quality was systematic analyzed; through the experiment, assemble and enforcement of the crucial technology, the similarities and differences of biscuit wheat and conventional wheat cultural technology were nailed down, and the group quality index about the high yield assorted with the high quality was suggested, substantiating and perfecting the cultural technical system of holding good quality and saving costs. And the productive technical regulations for the high quality weak tendon wheat Ning Wheat No.9 along river area were instituted. Major results were as follows:Through the analysis of the cultural factors that influencing the quality and yield of Ning Wheat No.9, and rounding building the high quality and yield group, the group quality index was advanced. Under the condition of realizing excellent quality, the dynamic indexes of the accumulation of dry matter of the group with the yield of about 400 kg/667m2 were respectively: at overwintering stage, the accumulation of dry matter was 50-60 kg/667nr, at reviving stage was 170-210 kg/667m2, at shooting stage was 280-360 kg/667m2, at boot stage was 740-870 kg/667m2, and at flowering period was 950-1100 kg/667m2; the dynamic indexes of group LAI were: at overwintering stage, the LAI was about 1.0, at reviving stage was about 2.7-3.4, at shooting stage was about 3.5-5.2, at boot stage was about 7-7.7, and at flowering period reached about 8.0; the group total grains number were in the range of 12000-14000 thousands/667m2 approximately; plant type index were: the tallness of individual plant was 80-85cm; the stem and tiller dynamic indexes were respectively: at the beginning of overwintering stage was 350-400 thousands/667m2, at reviving stage was 500-550 thousands/667m2, and the highest stem and tiller number was inadvisable when exceeding 600 thousands/667m2, the number of pinnacle seedling was 550-600 thousands/667m2, and the highest number was inadvisablewhen exceeding 650 thousands/667m2, the number of spike was 300-350 thousands/667m2, and it was not suitable to be under 280 thousands/667m2 generally, and the rate of producing spike was 50-55%.At the same time, the cultural technical system holding good quality and saving costs for high quality weak tendon wheat King Wheat No.9 was made clear. With density increasing, output was raised. And when density was overstepped a certain scope, output dropped, the output with the density of 120-160 thousands/667m2 had higher level. And with density increasing, grain protein and wet gluten content dropped, and the forming time of dough shortened. The suitable density of biscuit wheat was about 160 thousands/667m2. Proper reduction of nitrogen dosage and the anaphase nitrogen operation proportion, output level dropped appreciably, grain protein and wet gluten content reduced, grain unit weighs the water absorption of dough, forming time, and stabilization time submitted to drop tendency. Therefore, in order to realizing high quality and yield of biscuit wheat, the nitrogen dosages currently choose 12-16kg/667m2, and the nitrogenous fertilizer operations proportion choose 7:1:2. Some new fertilizers such as the biological organic fertilizer Faster, can raise wheat output, and grain protein and wet gluten content were higher than comparison, dough forming time and stabilization time were lengthened, which going against to improve the nutrition and processing quality, but the protein and wet gluten content did not exceeded the quality indexes of the national high quality weak tendon wheat, and the masses is accustomed to use relatively, in production it can be generalized to within measure. In chemic control technology, using different biochemical preparations, the influence to th...
