13 of Xudou Characteristics and cultivation techniques
 
 
Paper Keywords Xudou   13; Characteristics; yield; cultivation techniques   Abstract  briefly Xudou Characteristics of 13, while base fertilizer from the increased facilities, suitable for early sowing, planting sufficient moisture, rational close planting, growth stage management, introduced the cultivation Xudou 13 technologies to promote the cultivation of the varieties to provide guidance.     Xudou 13, Xuzhou, Jiangsu Province, Agricultural Science 139, 1993, No. Xudou used as female parent, Xudou 8618-4 strain (7 × Si Xudou beans 11) sexual hybridization for the male parent, hybrids bred by pedigree method. Crops in 2005 by the National Approval Committee. 2006 Guoyang pilot demonstration to introduce the species in 2007, large area.    1 Characteristics    that variety is sub-INDETERMINATE. Growth period of 102d, height 85cm, erect, main stem node number 17 or so, effective branches 1 to 2. Oval leaves, green, white, brown hair. 2 capsules per pod, pods brown, the end of pod about 12cm high. Grain flat oval, yellow seed coat, shiny, umbilical brown, grain weight is about 21.5g.  (1) high yield. In the product test Xudou than the average yield of 13 2 739 kg / hm  2 , than the increase Xudou 7.8% 10 in 2007, planting a large area in Guoyang County, the average yield of 2 673kg / hm  2 , of which St. Paul Town 333.3hm  2  planting base, the average yield of 2 800.5kg/hm  2 , the highest terraces up to 4 288.5 kg / hm  2 .  (2) strong resistance. Luxuriant plant growth, flowering early, long flowering, drought Waterlogging is strong, deciduous, and do not split pods, high yield, more lodging, resistance to soybean mosaic virus disease.  (3) good quality. 40% protein content, fat content of 21.3%, isoflavone content of 4.66mg / g, as high protein and high isoflavone varieties. Good commodity, grain uniformity, more than 98% of total grains.  (4) scope of application. Anhui Huaibei area suitable for the Soviet Union, southern Shandong, Henan, beans, wheat two crops a year of planting. Rotation Huancha to do well to avoid soybean cropping.    2 cultivation techniques    2.1 Adding base fertilizer  soybean crops need more fertilizer, grain and soybeans to produce 100kg corresponding stems, leaves , pods, shells, etc., need to absorb nitrogen and 5.3 ~ 9.5kg, phosphorus pentoxide 1.0 ~ 2.6kg, potassium 1.3 ~ 4.9kg. Soybean root system, and a nodule on the soil conditions require higher. Practice shows that the organic matter content of soybean yield land mostly in the 2% to 4%, and good soil structure, soil porosity, water, fertilizer, gas, heat coordination. To achieve nutritional and reproductive growth of soybean balanced development to ensure that there is thick vegetative early, but the lush growth in the late, not leggy, not lodging, flower and pod does not fall off, solid rate, high yield, growth appears to base fertilizer applied particularly important. Base fertilizer to use the full maturity of quality Tuza Fei, generally 30 ~ 45t/hm  2 ,You are not allowed to view links. Register or Login, standard N 105 ~ 150kg/hm  2 , SSP 300 ~ 450kg/hm  2 , Cl fertilizer 75 ~ 150 kg / hm  2 , with site preparation blending dead. Board crop planting bean fields, with high quality plus NPK fertilizer unit maturity Ren Xufen fertilizer or fertilizer for the kinds of fertilizer, so that kind of fat separation, but also have a good effect. Tension due to farm work, can not base fertilizer applied to soybean areas, can increase crop fertilizer Previous Crops to make use of residual fat soybean, the effect is also good. Suitable for early sowing   2.2 Short Summer Seeding of light and strong, short growth period, such as late planting, nutrition, short growing season, poor growth, and development of fast, can not effectively take advantage of the local growing season temperature, light and water, assimilation rate is low, the output is not high.  2.3 foot planting soil moisture during the summer soybean planting  positive high humidity, water evaporation, soil moisture difference plots, soil moisture to irrigation, seeding, or the rain making plant crops in order to achieve adequate moisture planting, a broadcast all seedlings. For the relatively flat land, crop irrigation can panels 1 , soil moisture after sowing Paping. Choosing the seeding drill on the way, progress rapidly, and the planting uniform, consistent depth is conducive to a broadcast all seedlings.
