Rapeseed seed price and planting method

Rape is the most important oil crop in China, also known as Brassica napus, Brassica campestris, Brassica campestris, etc., it is an annual or perennial herb of Brassica napus. The seed oil content is 3350%. At present, the main cultivation types are Brassica napus, Brassica napus, Brassica napus and so on. Let's take a look at the seed price and planting method of Brassica napus.

Sowing method of rapeseed

1. Select improved varieties: rape cultivated in China can be divided into three types: cabbage type, mustard type and Brassica napus type. Varieties with high quality, disease resistance, high yield and bolting tolerance should be selected, such as Xiaoqicui, Huaguan, Jinglu No.2 and so on.

2. Apply sufficient base fertilizer: usually apply high-quality and fully mature farm manure 3000kg / mu, diammonium phosphate 20kg / kg, potassium sulfate 10kg / 15kg or 45% ternary compound fertilizer 40kg / mu.

3. Seed treatment: before sowing, put the seeds in a place with sufficient light to dry for 3 hours, then soak the seeds in 50 ℃ warm water for 20 minutes for 30 minutes, and then soak the seeds in 20 ℃ ~ 30 ℃ water for 2 hours. After drying, the seeds can be sowed directly.

4. Fine sowing: generally sowing in late March, with seed of about 350 grams per mu, watering soil moisture before sowing, sowing after water infiltration, sowing 5 ditches with a width of 1 meter and a depth of 1.5 cm, and sowing seeds evenly in the ditch.

Planting methods of rapeseed

The main results are as follows: 1. Seedling setting: when two needles are unfolded, the first seedling is 3 cm apart, and when 4 leaves are 1 heart, the second seedling spacing is 8 cm 10 cm, leaving about 40 000 seedlings per mu. Less water is needed in the seedling stage, in general, it will not be watered without drought, and the seedlings will be watered 3 or 4 times after fixing the seedlings.

2. Ditch cleaning and drainage: in spring, Rain Water should pay attention to drainage. Waterlogging not only seriously affects the normal growth and development of rape, but also easily leads to the occurrence and prevalence of diseases such as Sclerotinia sclerotiorum, so special attention should be paid to ditch drainage in spring.

3. Spraying boron fertilizer: boron deficiency in rape will lead to the phenomenon of flowering and flowering. Foliar spraying was carried out in the bud bolting stage and early flowering stage without basal boron fertilizer, and boron fertilizer should be sprayed once in the rape seedling stage if there was serious boron deficiency in the soil without basal boron fertilizer.

4. Application of bolting fertilizer: in order to prevent late lodging and greedy green late ripening, fertilization after the year is generally not recommended, but appropriate amount of bolting fertilizer should be applied to the fields with insufficient wax fertilizer, poor growth and premature senescence. For the fields with large amount of wax fertilizer and vigorous growth, bolting fertilizer is no longer applied.

5. Prevent lodging: rape, such as poor management in the early stage, excessive growth or excessive fertilizer and water in the later stage, will cause rape lodging. In case of rape lodging, the plant should be righted as far as possible, some branches should be cut, and attention should be paid to clearing ditches and discharging stains in the fields with high humidity.

6. pest control: the diseases of rape in open field in spring crop are mainly Sclerotinia sclerotiorum, downy mildew, black rot and so on, and the pests are mainly aphids and leaf miners. The diseased leaves of old leaves should be removed in time for disease control, and pesticides can be used to control when the rate of diseased leaves reaches more than 10%.
