| Shanning 17 was a new high-oil, high-yield summer soybean variety and bred by Jining Academy of Agricultural Science using the theory of ecological breeding breeding. It has been examined and approved by the Crop Variety Examination and Approval Committee of Shandong Province in May 2013. High yield cultivation technology of Shanning 17 was studied in order to express the genetic potential and yield increasing effect of new variety, expand its promotion application area and extend the time limitation for promotion.The field experiments were conducted to study the effects of sowing date and density on growth period,agronomic and yield traits of soybean cultivar Shanning 17 as material from June 2013 to October 2013. The test results were as follows: with the delay of sowing date, the days of growth stage from seedling emergence to first blooming decreased, and late growth stage from first blooming to mature changed fewer, and growth period structure increases gradually; with the delay of sowing date, the number of branches, pod number per plant, grain number per plant increased gradually. there is a significant positive correlation; plant height, pod height, node number, 100 grain weight decreased gradually with significant negative correlation and its yield increased first and then decreased; with the planting density increasing, plant height, pod height gradually increased, and they are positive correlations between significant; node number, branch number, pod number, grain number per plant, decreased gradually, which are negative correlation significantly.100 grain weight had no significant difference and its yield increased first and then decreased; As a result the optimal sowing date of Shanning 17 is 17 th June, the suitable planting density is 180000 plants per hektare. If the sowing time is putting off due to special reasons in 17 th June, it should be followed early sowing planting and late sowing planting pattern.Different row spacing test of soybean cultivar Shanning 17 was conducted from June 2014 to October 2014. The test results showed that the row cultivation technology can reduce the soybean plant height and increase branch number and soybean productivity per plant, but had no effect on node number and 100 grain weight of soybean; Although more than 30 cm row spacing difference had an effect on the output of three elements to a certain extent, but can not improve the effective pods per plant, per plant the grain number and grain weight per plant and result in lower yields; when the spacing ratio is in the range of 10-20 cm, it can improve the soybean pod number, grain number per plant, grain weight per plant, compared with equal row spacing ratio; With 40cm/60 cm row spacing treatment, the yield was the highest of 4082.25kg/hm2 and increased by 10.58% than 50 cm treatment. The difference is extremely significant(P<0.01).The orthogonal experiment was conducted to study the effects of fertilizer application, planting density, foliar spraying times and chemical control frequency on yield traits of soybean cultivar Shanning 17 from June 2014 to October 2014. Test results showed that the yield of Shanning 17 between different factors was in the size of the order: rate of fertilizer application > planting density>chemical control frequency> foliar spraying times. The optimal planting pattern of Shanning 17 were planting density of 180000 plants per hektare, SACF complex fertilizer 300 kg per hektare, foliar spray fertilizer 1 times and chemical control 1 times.In view of the problems existing in the production of soybean, the study had also integrated the high yield and high efficient production technology system for core content of soybean with sowing seedlings, micro-spray irrigation, pest harm comprehensive prevention and control, full mechanized production in order to tap into the yield potential of Shanning 17 in the various production processes. |
