(1) Advantage performance 1. The oil content of Qingzao No. 2 spring rape was 45.2%, the content of erucic acid in oil was 0.65%, and the content of glucosinolate was 27.81μmol/g. 2. The high-yield effect of Qingzao No. 2 spring rapeseed is obvious, the effective branching part is about 5.3cm, the main inflorescence is about 70cm long, the plant height is about 176cm, the angle is dense, and the number of effective pods per plant is about 387. The yield per mu is 200-250kg, and the yield per mu is 250-280kg under high water and fertilizer conditions. 3. Qingza No. 2 has a total growth period of about 133 days, spring, early maturity, drought resistance and cold tolerance. Suitable for planting in areas below 2800 meters above sea level in our county. (2) Cultivation techniques of high quality and high yield 1. The cultivation technique of Qingza No. 2 is similar to that of other rapeseed. It is also necessary to establish an isolation zone during production, which can be isolated by natural barriers and isolated by different crops (such as wheat). If isolated with different crops, the isolation distance should be appropriately increased. 2. Select the variety of the ecological zone. 3. The determination of the sowing date should not only meet the requirements of the nature of rape, but also avoid the interference of unfavorable factors. The Sichuan River area in our county is generally planted in the middle and late March, and the mountain dry land is broadcast in mid-April. 4. For the field with a yield of more than 250kg per mu, the number of plants per mu is between 10,000 and 30,000. 5. Spring rapeseed has a short growth period. Although the seedling stage is spent on soil with a large amount of organic fertilizer, due to the low temperature in early spring, the activity of soil microbes is restricted, the nutrient decomposition is slow, the seedlings can not get nutrients in time, and the seedlings are in starvation at the beginning. , slow growth. Therefore, it is necessary to apply seed fertilizer to ensure the quick-acting nutrients of the seedlings and obtain strong seedlings. Generally, 15 kg of superphosphate and 5 kg of urea are used per mu, and mixed with appropriate organic fertilizer before sowing to make a granular fertilizer, which is sown with the seeds. 6. The spring rapeseed seedlings are mainly yellow strips and stems, and the control method is to mix 5% phorate with 1.5kg mixed seed; if the locusts are found in the growing season, dichlorvos and dimethoate 600-1000 times Take control. 7. High-yield field rapeseed generally turns yellow in the lower part of the main order, and the upper part of the branch becomes light green, and the grain turns reddish brown, that is, the harvest is "live" in the yellow ripe stage. should.
