Embodiment 1

[0036] S11. Select fine seeds and treat the seeds: sunflower seeds that have been de-mildewed and impurity-removed are dried for 1-2 days, and the accumulation thickness of the seeds is controlled to be 2 cm during drying. Soak the dried seeds for 6 hours, and mix them with high-efficiency fungicides After planting, to prevent diseases such as sclerotinia and downy mildew, spraying with carbendazim can kill the small sclerotia and hyphae attached to the surface of the seeds;

[0037] S12, apply sufficient base fertilizer, apply 30 cubic meters of decomposed and fermented lime soil manure per hectare, apply 150 kilograms of diammonium phosphate and 100 kilograms of urea;

[0038] S13. Divide the cultivated land into sunflower planting blocks 10 and pest-resistant crop planting blocks 20, the sunflower planting blocks 10 and pest-resistant crop planting blocks 20 are arranged in a staggered manner, and the pest-resistant crops include pyrethrum and / or wormwood.

[0039] S14. A d...

Embodiment 2

[0046]S21. Select fine seeds and treat the seeds: dry the sunflower seeds that have been de-mildewed and decontaminated for 1 to 2 days, control the accumulation thickness of the seeds to 3 cm during drying, soak the dried seeds for 6 hours, and mix them with high-efficiency fungicides After planting, to prevent diseases such as sclerotinia and downy mildew, spraying with carbendazim can kill the small sclerotia and hyphae attached to the surface of the seeds;

[0047] S22, apply sufficient base fertilizer, apply 40 cubic meters of decomposed and fermented lime soil manure per hectare, apply 200 kilograms of diammonium phosphate and 150 kilograms of urea;

[0048] S23, the cultivated land is divided into sunflower planting block 10 and pest-proof crop planting block 20,

[0049] The sunflower planting blocks 10 and the pest-resistant crop planting blocks 20 are arranged in a staggered manner at intervals, and the pest-resistant crops include pyrethrum and / or wormwood.

Embodiment 3

[0057] S31. Select fine seeds, and treat the seeds: sunflower seeds with mildew and impurities removed in the air for 1 to 2 days, control the accumulation thickness of the seeds to 2.5 cm during drying, soak the sunflower seeds for 6 hours, and use high-efficiency fungicides After seed dressing, to prevent sclerotinia and downy mildew and other diseases, spraying with carbendazim can kill the small sclerotia and hyphae attached to the surface of the seeds;

[0058] S32, apply sufficient base fertilizer, apply 35 cubic meters of decomposed and fermented lime soil manure per hectare, apply 175 kilograms of diammonium phosphate and 125 kilograms of urea;

[0059] S33. Divide the cultivated land into sunflower planting blocks 10 and pest-resistant crop planting blocks 20, the sunflower planting blocks 10 and pest-resistant crop planting blocks 20 are arranged in a staggered manner, and the pest-resistant crops include pyrethrum and / or wormwood.

Abstract

The invention discloses a sunflower cultivation method. The method comprises the following steps: cutting arable land into sunflower planting blocks and pest-resisting crop planting blocks, and planting sunflowers and Vernonia anthelmintica Willd and / or Artemisia vulgaris on the sunflower planting blocks and the pest-resisting crop planting blocks to prevent and control the pest and disease damage. Meanwhile, the Vernonia anthelmintica Willd and the Artemisia vulgaris are good economic crops, so that the economic benefit of sunflower planting is improved.

Description

technical field [0001] The invention relates to the field of sunflower cultivation, in particular to a sunflower cultivation method. Background technique [0002] When sunflowers are cultivated in the open field, the root system is relatively developed and drought-resistant. Watering is not much in spring, and supplementary watering is required when the temperature rises in early summer and the evaporation of water is large. Sunflower is a light-loving flower, which requires sufficient sunlight throughout the growth and development period. From budding to flowering, it is the peak of water demand, and the water demand accounts for about 43% of the total water demand. The lack of water in this period has a great impact on the yield, and the water demand from flowering to maturity is also more, accounting for about 38% of the total water. If the water is insufficient, it will not only affect the yield, but also reduce the oil content. Throughout the sunflower growth stage, th...
