Where are sunflowers grown on a large scale?

There are 20 provinces and municipalities (autonomous regions) with large sunflower cultivation areas in China. It is mainly divided into five production areas:

Northeast China, Inner Mongolia region.

North China. It mainly includes the eastern and northern parts of Hebei Province, the Beijing-Tianjin region, the central and northern parts of Shanxi Province and the northern part of Shandong Province.

Xinjiang District. Yellow River Loop. It includes the Zhangye region of Gansu Province, the northern part of Ningxia Hui Autonomous Region and Shaanxi Province.

Yunnan-Guizhou Plateau District. Including Yunnan, Guizhou and Sichuan provinces.

Sunflower Theme Park is located on the side of National Highway 107, on the road from Doudian to Liuli River, on the east side of National Highway 107, driving from Beijing City, you can take the Jingshi Expressway, go out from the Doudian exit, take a one-way line and then cross the bridge hole, turn right, you will get on the 107 National Highway (Jingbao Highway), you will pass by the Doudian roundabout, continue to move forward, you should not be too far away to see a piece of sunflower on the left side of the road. Inside, the sunflower planting area is larger. If you like the beautiful picture of Chen Kun and Zhou Xun lying in the sunflower field in the TV series, it is recommended that you go to this theme park to have a look.

The salinized soil in the southeast of North China and Hebei Province is widely distributed, and the organic matter content is mostly about 1, which is the key area for the transformation of medium and low-yield fields in Hebei Province. Sunflower has strong drought resistance, barren resistance, and salinity tolerance, and planting sunflower on salinized soil can create considerable economic benefits.

The Wafangdian, Pulandian and Zhuanghe areas of Dalian City are close to the Yellow and Bohai Seas and have a large area of saline-alkali land. For many years, due to the lack of water resources, large areas of saline-alkali land have not been fully exploited. After two years of screening and research, Sunflower Xinkui No. 6 for oil was successfully planted on saline-alkali land, with a yield of 285 kg of sunflower seeds per mu.

New technologies have played a role in saline land.

Large-scale planting sunflowers should choose a wide and flat land, sowing in the spring 3 4 months is the best, with a new high fat film dressing to improve the seed germination rate, seed spacing about 20cm, a hole to sow 1 2 seeds, 10kg of compound fertilizer per mu as base fertilizer, a week to germinate, after germination to pay attention to seedlings and weeding.

Sunflower sowing in the spring 3 4 months is the best sowing, about how to plant sunflowers in a large area, the planting land should choose a wide and flat land, convenient irrigation, the soil quality is the best sandy loam, the soil is deep ploughing and layering, the depth is about 30cm, 10kg of compound fertilizer per mu is applied as base fertilizer, and other crops should not be planted before planting sunflowers.

First of all, the sunflower seeds are damaged and shriveled to pick out, the seeds are selected as edible varieties, the flower plate is large, the yield is high, the seeds should be dressed with a new high-fat film, for disinfection, and then the seeds are soaked in 30 warm water for 24 hours to promote germination, which can reduce the disease of sunflower and improve the germination rate of sunflower.

Planting sunflower density is large, the flower disc is small, the density is small, the flower disc is large, generally 3000 plants per mu is the most suitable, the seed spacing is about 20cm, the average seeding hole is 1 2 seeds in the middle age, the seed depth is between 3 5cm, it can germinate in a week, in order to ensure the yield, it is necessary to observe in time after germination, the lack of seedlings should be filled, and the two plants can be transplanted if they are alive, and the seedlings that survive too much also need to be pulled out.

Generally, after the seedlings survive, they need to be weeded regularly, they can be weeded anytime and anywhere, they can also be weeded regularly, and the whole growth period can be weeded regularly and 3 times, the first time for the seedlings to grow two pairs of leaves, the second time in the seedling, the third time in the seedling 15 days after the seedling, weeding can also be combined with the cultivator shallow tillage to loosen the soil.

The first top dressing is applied after the third weeding, 5kg of phosphorus fertilizer per mu, 10kg of nitrogen fertilizer, top dressing once a month later, the amount of phosphate fertilizer gradually increases, nitrogen sells and slowly decreases, the first irrigation is in the flower bud when it grows, the second irrigation is in the flowering period, and the third irrigation is in the flower disc when it is about to mature.

Introduction to Sunflowers.

Sunflower is a plant of the genus Sunflower in the family Asteraceae. Its plant height, some up to 9 meters, has an erect stem. Also called sunflower, sunflower, sunflower, sunflower, sunflower, sunflower. The main garden varieties of sunflowers are golden bear, laughing, yellow strong, sunspot, music box, etc.

Sunflower growing conditions.

1. TemperatureSunflower is a tropical crop, which is very adaptable to temperature, likes a warm environment, but is also very cold-tolerant. Its seeds are highly resistant to low temperatures. Sunflowers can grow normally as long as the temperature does not fall below 10 during the whole growth process.

In the right temperature range, the higher the temperature, the faster the development. 2.Water sunflowers prefer a moist environment but require different water at different stages of growth.

From sowing to budding, they are drought-tolerant and do not need much water, accounting for only the total water requirement. Proper drying is conducive to root growth and improves drought resistance. 3.

Light sunflowers prefer sunny environments. Seedlings, leaves, and flower discs rotate with the sun and are all very phototropic. If the maintenance environment is not lit in sufficient light, it will have an impact on its growth and yield.

It is best to take care of them in a sunny place. Sunflower is commonly found on hillsides and fields, and is widely distributed in China, such as Heilongjiang, Jilin, Liaoning, Hebei, Henan, Shandong, Anhui, Jiangsu, Zhejiang, Hubei, Jiangxi, Sichuan, Guizhou, Yunnan, Shanxi, Shaanxi, Gansu, Qinghai, Inner Mongolia and other places. From 2010 to 2010, sunflowers were sown all year round.

The best time is from January to April in early spring or September to October in autumn, and flowering is 60-70 days after sowing. If sown in May-August or November-December, flowering takes about 70-80 days.

Sunflower planting time.

The yield of edible sunflower per mu is 150-200 catties, and the yield of oil sunflower per mu is 200-250 catties, and the purchase price is 14-16 yuan per catty, which is basically about 1000-2000 yuan per mu.
