3 Environmental Quality Requirements

3.1 The selection of the production site environment is based on the NY5010 standard.

3.2 The base is flat, water and fertilizer conditions are good, and water-saving irrigation is promoted.

3.3 After the harvest, clean the pastoral area, destroy the leaves and leaves, and timely recover the residual agricultural film.

4 Cultivation techniques

4.1 Variety selection The rapeseed varieties with high quality, high yield, resistance to pests and diseases, strong resistance to stress, wide adaptability and good commercial quality are selected.

4.2 Nursery

4.2.1 Seed Processing

Select one of the following methods depending on the type of pest:

4.2.1.1 Seed dressing (downy mildew) with 25% metalaxyl wettable powder with seed weight 0.3% before sowing.

4.2.1.2 soak in seeds with warm soup for 25 minutes, soak after cooling and drying.

4.2.1.3 Use NR 751 to seed 1%-1.5% (soft rot).

4.2.2 Cultivate disease-free strong seedlings

4.2.2.1 Preparation of Seedling Soil The garden soil not planted with cruciferous crops within 3 years is mixed with high quality organic fertilizer, and is blended and sieved.

4.2.2.2 Sterilization of nursery soil Use 50% carbendazim WP and 50% thiram WP to mix 1:1 per square meter.

4.2.2.3 The use of nutrients, paper bags and other mulching root. The seedling age is controlled at 25-30 (days), and when it grows 5-6 (slices) of true leaves, it is suitable for colonization.

4.2.3 Protected areas In mid-January, nurseries will be planted in the greenhouse, in mid-February greenhouses will be divided into seedlings, and planted in late February and late March.

4.3 Colonization

4.3.1 Fertilization for soil preparation Every 667m2 application of organic fertilizer 5000 kg/667m2, special fertilizer for vegetable formulation 20kg, deep-turn 20cm, Fuping.

4.3.2 The planting density is planted to the base of the first true petiole at a plant spacing of 15cm x 20cm and watered with the plant. The density is 22,000 - 23,000 strains/667m2.

4.4 Management after Planting

Appropriate ventilation after easing the seedlings and keeping the temperature at 20°C. Ploughing 1-2 times in sunny days, when the plants began to grow new leaves, topdressing urea 10 kg/667m2.

5 Harvest and follow-up management

According to the requirements of the goods, timely harvesting is required. The harvested rapeseed should not be washed with sewage, and the tools used in the harvesting, packing, transporting, and storing processes should be clean, hygienic and free from pollution.
