Huyouza No.1 is a double-low recessive nuclear sterile hybrid combination selected by the Shanghai Academy of Agricultural Sciences. The average yield per mu is about 140 kg, ranking first in the district test. In 2003, he participated in the rapeseed production trial in Shanghai, and increased production by more than 10% over Shanghai Oil 15.
The plant height of Huyouza No. 1 was 154.0cm, with 9 effective branches at one time, and 5 effective branches at the second time. The number of effective pods per plant was 450, and the number of fruit per pod was 19 grains. The oil content reaches 40%. The fertility period is 232 days, resistance (resistance) to Sclerotinia sclerotiorum and virus disease.
Cultivation points
1, timely sowing, nurturing strong Zhuang: September 20-25 sowing, Putian and Daejeon than 1:6, three true leaf spray 150ppm paclobutrazol, or 18ppm uniconazole, the age of 40-45 days.
2, timely planting, reasonable close planting: Transplanting period in early November is appropriate. Transplanting density, short and strong seedlings, and 7500 plants/mu are preferred in the case of early planting, and 9000 plants/mu are generally appropriate.
3, scientific fertilization, early and stable growth: early growth is relatively fast, must be transported by fertilizer and water to promote early and strong winter hair. Principles of fertilization: Reapply basal fertilizer or with root fertilizer, early application of Miaofei and wax fertilizer, strictly control the moss fertilizer, skillfully apply flower corner fertilizer. Pre-spring and post-harvest use fertilizer ratio of 80%: 20%.
4, deep ditch sorghum, pest control and disease prevention: the ability of moisture resistance is less than the return of oil 50, after the rape transplants need to clean up the ditches, three-channel matching, so that drainage smooth, reduce wetness. Rape seedlings and cabbage caterpillars are well protected during the seedling stage and wintering period, and prevention and treatment of sclerotinia are well done during the early flowering stage and flowering stage.
5, timely harvest, yield bumper harvest: the species is particularly good shattering, when fully mature, the fruit will naturally burst, suitable harvest time is about 80% of the whole field of fruit is yellow, most of the spindle pod black grain brown
