Detailed introduction

★Main characteristics of the variety, cabbage type hybrid. Phantom seedlings are semi-erect, with medium-sized leaves at the top, medium-sized leaves and deep leaves at the top. The petals are yellow, medium in length, wide, and laterally folded. Seeds black-brown.

★Adaptability: The average of the whole growth period is about 206 days, which is 1 day earlier than that of the control Qin You 7. The average plant height is 159cm, the number of effective siliques per plant is 436, the number of grains per horn is 22.4, and the weight of 1000 grains is 4.0g. Lodge resistance is strong. After testing by the Ministry of Agriculture's Oil and Products Quality Supervision, Inspection and Testing Center, the average erucic acid content is 0.0, the glucosinolate content in cake meal is 19.49 micromol/g, and the oil content is 44.28. The yield per mu in the first growth cycle was 193.49kg, which was 12.6 higher than that of the control Qin You 7. High yield cultivation can reach about 700kg.

★Main cultivation measures:

1. Timely sowing in the middle and lower reaches of the Yangtze River: transplanting seedlings in late September and direct seeding in mid-late October. Cultivate large and strong seedlings for transplanting before competing for winter. Note: One week before transplanting, spray paclobutrazol by half in beginning of winter or before bolting to control prosperity.

2. Reasonable close planting: under the medium fertility level, the reasonable density of seedling transplanting is 7000~9000 plants/mu. Direct seeding can be appropriately dense planting 1.0~13000 plants/mu.

3. Scientific fertilization: pay attention to the reasonable ratio of nitrogen, phosphorus and potassium, apply base fertilizer again, and apply 45-60kg of compound fertilizer per mu; Early application of seedling fertilizer, boron fertilizer must be applied, and bottom application of borax is 1-1.5kg per mu. 4. Prevention and control of diseases: pay attention to the prevention and control of sclerotia. Spray 40kg of sclerotiorum, iprodione and imidacloprid with water one week after seedling and initial flowering respectively.

★Suitable planting area and season: suitable for autumn planting in the main rape producing areas of Hubei, Shanghai, Zhejiang, Anhui and Jiangsu south of the Huaihe River, Sichuan, Guizhou, Yunnan, Chongqing, Shaanxi Hanzhong and Ankang.
