I. Variety characteristics: This variety belongs to the new high erucic acid rape variety in the medium-ripe industry of Brassica. The erucic acid content is 57%, the oil content is over 39%, and the winter is strong, semi-upright, and the plant height is about 197cm. 18-20 capsules, about 3 grams of 1000-grain weight, strong resistance to disease, strong resistance, high seedling transplanting yield, generally more than 150-200 kg per mu. Second, high-yield cultivation techniques: (a) timely early sowing, planting early in the seedlings. According to the temperature conditions in Mianyang City, the nursery will be planted on September 15-20. The ratio of the seedbed to the field should be 1:4-5, the seedling age should be controlled within 25-30 days, the seedling height should be 13-17 cm, and the number of true leaves is 4. - When transplanting 5 tablets, transplanting the first day of the afternoon with appropriate soaking water to soak the nursery bed to prevent shoots from sprouting. The seedlings must be planted on the same day and the roots should be poured after the planting. The live broadcast schedule will be broadcast before October 5. (b) Cultivate strong seedlings and plant them in close proximity. Use transplanted seedlings that grow robustly and have uniform size. Generally, 800-1,001 acres are planted in acres with a spacing of 1-1.2 feet and a 0.5-0.6-foot pocket spacing. It is best to implement a wide and narrow row of 1.2-1.4 feet wide and 0.8-1 feet narrow. Live seedlings are timely and uniform, and about 15,000 Dwarf seedlings are suitable. (c) Scientific fertilization. The principle of fertilization for high erucic oilseed rape is to use enough base fertilizer, apply early seedlings and open fertilizers, and reapply budded fertilizer. The proportion of organic fertilizer is increased in the base fertilizer, and nitrogen, phosphorus, and potassium fertilizers are reasonably matched with 12-14 kilograms of pure nitrogen per acre according to 1:0.5:0.5-0.8. Before the end of December, full-scale chemical nitrogen fertilizer was applied, and 0.5-1 kg of borax was used as the base fertilizer, or 100 kg of 30 kg of water was used for the root spraying during the bolting period and the initial flowering period; the soil with serious boron deficiency should be in the seedbed and The application of boron fertilizer during transplanting is performed by spraying the seedbed with 0.4% borax solution 1-2 days before transplanting or applying 200g borax per acre to the root (15-20 tam) to prevent " Flowers are not real." (d) Prevention of pests and weeds. The seedlings in the second leaf stage or 3 days before transplanting are sprayed with 10 ml of water per acre in the green uniform spray to prevent aphids, cabbage caterpillars, and beetles; the sclerotinia is controlled by the quick flowering period or flowering stage. After weeding, the weeds were in the 2-3 leaf stage. Weedicides were used to control grass weeds or to control broad-leaved weeds with high gram suspensions.
