Product Description
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. At the
anthesis stage, the disk is flat, about 25-30 cm in diameter, the pollen
quantity is large, the self-crossing seed setting rate is above 99%, and the
recovery rate is 100%. 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. It can
be planted in season in Central China, East China, northwest and Northeast
China.
