Main characters

It is the newly bred three-line hybrid oil sunflower variety with high purity, good resistance and it is an early maturity variety.

The yield of high-yield plots per mu has the potential yield of 325kg, and the yield of general plots per mu is about 250kg.

① It is an early maturing variety, high yield and disease resistance, thin seed coat, no hollow, high oil type hybrid variety.

The growth period is about 85 days for spring sowing and 80 days for summer sowing.

It belongs to spring and summer varieties.

② Sow in dry land, the stem is stout, shorter, when the bend is mature, the plant height can reach about 77 cm, neat and uniform, the leaves face down alone, resistant to looping, the leaves are up-thrust, the petiole is short and strong, the average leaves are 19-20, unbranched, the young stem and leaf vein are green, yellow flower disc, and the lixate petals are bright yellow.

Achene is black gray stripe, bulk density is more than 10% higher than the general variety.

The oil content of seed kernel is above 75%.

After many years of planting in experimental fields, the yield per mu has the potential yield of 325kg in normal years.

Main cultivation measures:

① Under the condition of low temperature in spring sowing, the first four pairs of leaves of seedlings are prone to lateral branches, which is a normal nutritional physiological phenomenon, and it is best to knock them out.

② The sowing amount per mu is 450-500g; Sowing depth: the sowing depth of a single grain is generally about 3cm.

③ According to the soil conditions, for plots with good soil fertility, sufficient water, fertilizer and light, the seedling protection per mu must reach 3800-4000 plants / field, the plant spacing is 30-35cm, and the row spacing is 45-50cm.

④ 3500 seedlings / mu in plots with poor soil fertility.

⑤ Washing and land preparation Continuous cropping should be avoided, deep ploughing and soil preparation should be carried out, and raking should be carried out to increase soil moisture.

Field management: weeding should be carried out in time during the seedling period.

If there is no special drought during the growth period, watering should be minimized to facilitate squatting; Irrigation shall be carried out in time according to the soil conditions at the initial stage of budding.

In case of drought at the grouting stage, the plots with irrigation conditions shall be irrigated in time; Sunflowers are afraid of waterlogging.

Therefore, flowering and pollination and mature harvest should be considered during sowing to avoid the rainy season.

The fertilization amount is generally 10-15kg urea, 10-15kg diammonium phosphate and 10-15kg potassium sulfate per mu, or 30-40kg ternary compound fertilizer per mu.

After application of urea from budding to flowering, 5-10kg / mu; The quantity and method of fertilization can also be arranged separately according to the local actual situation.

Adaptability, planting area and planting season:

Sowing can be started in North China from March 20 to April 20 (in spring sowing areas, sowing can be started when the soil temperature is stable above 15 ℃), and planting in summer should generally be sown in early July.
