Effects of Sowing Time and Sowing Amount on Yield and Quality of Forage Rape

【Objective】 The research time of no-till multiple cropping forage rape is short, and the research on suitable date and quantity of sowing in Northern Xinjiang Area is not enough, The purpose is to provide theoretical support. 【Method】 The experiment adopted the split zone experiment design, with the sowing period as the main area and the sowing amount as the secondary area. Two sowing periods, four sowing amounts were set, and three replications were carried out in a total of 24 plots. 【Result】 The results showed that sowing dates, sowing amounts had significant effects on wet weight, height of plant and number of harvested plants. Under normal seeding conditions, when the amount of Siyou 2 was 12 kg/hm², the yield was the highest, 81,893.0 and 87,309.9 kg/hm², in 2016 and 2017 respectively, with the best quality. 【Conclusion】 Multiple cropping forage rape growth duration is 60-65 days, and the accumulated temperature is between 1,100℃ and 1,500℃(≥10℃). The selection of suitable sowing time and sowing quantity, yield and quality can meet the requirements of forage grass and the requirements of replanting wheat in most areas, and is the first choice for replanting wheat in cold areas.
