Sunflower has a short growth cycle and good benefits, how to increase the yield of sunflower?

Traditional sunflower varieties are sown in June, and the sunflower seeds are seeded, and the best sowing is after June 20. Sunflower seeds are sown at the beginning of autumn on August 8, and can be harvested before the beginning of winter. The spring sowing time is 10 cm, and the soil temperature reaches 8 10 for 5 consecutive days, and the seeds can be sown.

Generally speaking, the sowing time for conventional varieties is in late April, and the spring sowing time for hybrid varieties is generally in mid to late May. Our Gansu side mainly sows seeds according to the solar terms of the Qingming Festival.

Sunflower should choose a reasonable rotation method, choose a good stubble, should not be cropped, and should not be planted in low-lying and waterlogged plots, except for sugar beet and deep-rooted forage, other crops can be used as sunflower stubble. Crop rotation and stubble. Continuous cropping of sunflowers will cause excessive consumption of soil nutrients, especially potassium, soil fertility will be difficult to recover, and pests and weeds will also be aggravated by continuous cropping.

The rotation period is generally 3 to 4 years. Beans, cereals, etc. were good harvests for sunflowers.

When the back of the flower disc has turned yellow, the stalk of the plant has turned yellow, most of the leaves have withered and fallen off, the supporting leaves have turned brown, the tongue-like flowers have fallen off, and the seeds have hardened and shown the color of this variety, it should be harvested in time. It can also be harvested about 36 days after the sunflower flowering period, the sowing time of sunflower is generally 3 April, the suitable temperature for sowing is 18 25, and the germination is usually about 5 7 days after sowing. The basic principle of sowing date selection is to sow early or late according to the law of saline-alkali occurrence, so that the seedlings can avoid the damage of saline-alkali.

It is necessary to kill insects regularly, kill green insects at the seedling stage, and kill insects after the flower plate. In the end, the flower plate is big, if it is a dwarf sunflower, an oil-squeezed variety, it must be supported by a wooden stick, otherwise the plate will fall to the ground, and all the melon seeds inside will rot.

Select the best species and process them. Select excellent varieties with high yield, high quality, good quality, good commerciality, resistance to leaf spot, sclerotinia resistance, low hollowing rate, high germination rate and strong germination potential, and carry out seed treatment, so as to give full play to the role of "making the best use of the seed and making the best use of the land".

The use of artificial pollination can reduce the empty shell grains of sunflowers, improve the quality of seeds, and ultimately increase the yield and income.

It should be ventilated, and it should be planted in a sunny place, and the spacing should be reasonable, to prevent sunflower pests and diseases, to remove weeds in the field, and to fertilize in time.

1. Seed selection. Generally, excellent varieties with strong stress resistance, good yield, and suitable for local conditions are selected.

2. Land selection, stubble selection and land preparation. Choose plots with deep tillage layers, flat terrain, good drainage, and abundant organic matter. Cereal crops are a good precursor to sunflowers. In terms of production, the general rotation period is 5 to 7 years.

3. Pay attention to reasonable fertilization. Generally, it is combined with farmhouse fertilizer and chemical fertilizer to fertilize in a certain proportion.

4. Pay attention to field management and pest control.

Sunflowers should be fertilized so that they can grow taller and grow more sunflower seeds.

Nowadays, many farmers are choosing some plants with economic value to plant, and it is a good choice to plant sunflowers to obtain some higher economic value. So how long is the growth cycle of a sunflower? Is it possible to do it two weeks a year?

Keep this question in mind today, for a moment. <>

1. The growth cycle of sunflowersThe growth cycle of sunflowers generally ranges from 85 to 120 days. Sunflowers, also known as sunrise flowers, generally grow towards the sun, so they are also called sunflowers. oneThe growth cycle of sunflower is divided into 4 cycles, seedling stage, budding stage, flowering stage, and maturity stage.

If the growth cycle of sunflowers is completed after these four periods, they can be harvested, and then sold and bought appropriately to obtain relatively high economic returns. Therefore, in terms of the growth cycle of sunflowers, if conditions permit, it is possible to achieve two crops a year. <>

2. Fertilizer for sunflower growth The soil in which sunflowers grow should be very nutritious, ensure that the light is abundant and the temperature is not high. It is possible to achieve two crops a year, and what farmers need to do at this time is to do some pests and diseases that occur when sunflowers grow. In this way, the material can meet the needs of the next growth, and achieve double cropping a year to obtain higher income value.

At the same time, we should also pay attention to whether the sunflower grows strong enough, if not, we should choose a better fertilizer in the fertilizer to maintain the nutrients needed for the growth of the sunflower without polluting the environment. <>

3. Sufficient sunlight The growth of sunflower needs sufficient sunlight, so it needs to be closer to the equator in terms of regional requirements to ensure that it can obtain sufficient sunlight to produce more organic matter. Therefore, for the sunflower growth cycle, it needs sufficient sunlight, and to ensure that it grows in a sunny area, choose the southern region of China.

Therefore, for the sunflower growth cycle, it is necessary to achieve double cropping in one year and ensure sufficient sunlight. These are some thoughts on the sunflower growth cycle.

More than 80 days to more than 120 days. It can be grown twice a year, sunflowers are a very good creature, and sunflower seeds are very delicious.

The growth cycle is about 85 120 days or more. Of course, it can be done, but it must be cared for, and the suitable growing environment must be ensured, and the temperature should not be too low, and the humidity must be low.

The growth cycle is 6 months, and you can do two crops a year, as long as the temperature is right and the fertilizer of the soil can keep up, it is okay.

The stems of sunflowers contain a small amount of potassium chloride, which can improve the soil in a short time, so it has become the main crop for the management of saline-alkali land. Shenmu City is located in the northern part of Shaanxi Province and is one of the areas with a lot of sunshine and strong radiation. It is rich in light and heat resources, which is suitable for growing sunflowers.

Since 2019, Shenmu City has focused on the structural reform of the agricultural supply side, accelerated the adjustment of the agricultural industrial structure, reduced the planting area of traditional crops and corn, and introduced a large number of special crops sunflower"Appreciate sunflowers and transform agriculture"The theme of the Shenmu Sunflower Cultural Festival.

It has effectively promoted the development of the sunflower industry. Sandy soils, low-lying lands prone to water accumulation, land with severe salinization and land susceptible to strong winds should be avoided and reverse planting should be prohibited. If the first crop is corn, make sure that atrazine has not been used when growing corn.

Avoid beets, grass, or potatoes before planting sunflowers. Because legumes are susceptible to scleromycosis, which affects the growth and development of sunflowers, they should be avoided as the first crop planted in sunflowers.

At the same time, sunflowers should not be cropped continuously, and generally should be rotated with melons, wheat and other crops for more than 3 years. Choose the right land. Although sunflowers are not particularly strict on soil requirements and are highly adaptable, in order to improve yield and quality, choose soil with a pH value between as much as possible, and soil that is too acidic or too alkaline is not conducive to its growth.

The soil layer is fertile and deep, and it needs to be rotated for about three years, which is more conducive to the growth of sunflowers. In order to ensure the yield of sunflowers, it is generally necessary to choose plots with a certain fertility for planting.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

To improve the yield of sunflowers, we must first choose varieties with strong stress resistance, good yield, suitable for local conditions, seed purity higher than 98%, germination rate higher than 90%, and also need to choose suitable land.

Sunflowers are a common crop, and if you want to increase your yield, you must stop in a place where there is plenty of square, and choose loose and fertile sandy soil to grow.

First of all, sunflowers have high requirements for fertilizer, so you must choose very fertile land, and you must do a good job of artificial pollination to increase yield.

The first step of selection is definitely seed selection, and the quality of the selection determines one of the reasons for the yield. There are many varieties, and sunflowers are a favorite food for mass consumers. However, some varieties are not particularly good in disease resistance, and if one of its fullness does not reach a certain standard, then it will definitely have a certain impact.

After all, as the old man said, a good dragon gives birth to a dragon and a phoenix, and a mouse gives birth to a hole, which shows that the genetic factors of seeds still account for a certain proportion. Just like in life, some parents are taller people, their children will be taller, some parents are smaller, and most of his children are relatively small, which has a certain relationship with genetic factors, and the same is true for plants. <>

Step 2: Choose a better plot, which will also affect the yield of sunflowers. All the more fertile land, then nature can better contribute to the growth of sunflowers, for some water-scarce and arid land, land with little organic matter, then there is no sufficient nutrition, sunflowers want to grow well, often more difficult. In fact, this also tells us that when choosing land, we must find some more fertile, not those yellow mud land.

The third step is more important, then it is fertilization. Fertilization is indispensable for planting, especially in the growth and germination stages. Sunflowers also need more elements, potassium fertilizer, phosphate fertilizer, nitrogen fertilizer, green fertilizer, farmhouse fertilizer, these should be added in moderation, if some elements are insufficient, then it will also affect the growth results.

Step 4: Pest and disease management: This is a top priority. As long as it is edible food, people like some insects and birds, they also like it, so we must do a good job in the treatment of these pests and diseases, especially some birds and insects, to do a certain amount of prevention, the same kind can be sprayed with pesticides, birds can hang some scarecrows. For the prevention of diseases, then certain pesticides can be sprayed.

First of all, we must choose the best varieties, and secondly, we should pay attention to the prevention and control of pests and diseases, and scientific fertilization.

Top dressing should be done on time, regular watering should be carried out, attention should be paid to insect pest prevention, and sunflower planting skills should be learned.

You should learn the skills of planting sunflowers, and you should remove weeds frequently, and you should also observe the growth of sunflowers, and be prepared to prevent insect pests.

If you have never planted sunflowers, you can see in all the information that the temperature needs to reach 18 24 is the best sowing period, and it is obvious that it is not suitable to cultivate sunflowers as oil crops, because sunflowers also need at least 100 days or more 10 Here, we are mainly talking about sunflower seeds, that is, the fruits of sunflowers. If sunflowers want to produce high-yield and high-quality sunflower seeds, they must study more planting technology, and sowing plays a very key role in the whole planting process.

Because in recent years, in order to make fuller use of land resources, people will rush to plant oil sunflower after wheat harvesting, which is also sunflower series, but its seeds are much smaller than sunflower seeds, but they are fuller than sunflower seeds, mainly used to extract edible oil, sunflower seeds have a higher oil content, and are one of the main oil sources of edible vegetable oil. The types of sunflowers can be divided into three types: edible type, oil type and intermediate type according to the seed use and growth method.

Sunflower is divided into edible sunflower and oil sunflower, the main use of sunflower is fried melon seeds, and the main use of oil sunflower is to process sunflower oil. However, whether it is edible sunflower or oil sunflower, the sowing time and planting method are basically the same. The sowing date of sunflowers is mainly determined by the temperature of the planting site, and sowing can be carried out when the temperature of the soil layer is stable at 8-10 degrees for a week.

Early sowing can make full use of light, heat, water and other resources, and can avoid the rainy season in the full flowering period. Before sowing sunflowers, the soil moisture should be carefully checked, and the land preparation method should be determined according to the soil moisture and different varieties. Conventional varieties with a long growth period, because of the early sowing period, generally in mid-April, when the soil moisture is better, can be taken first land preparation and then sowing the method.

Sunflowers are planted at different times depending on the climatic conditions, but they can be sown all year round, but they grow best in spring and autumn. Sowing is generally carried out in April in Northeast China, March in North China, and planting in March in the south.

Potted sunflowers are usually sown between April and June, and the higher the temperature is between 18 and 25 degrees, the better it is for the seeds to germinate. To plant sunflowers, choose suitable seeds, then give them germination treatment before planting, and bury them in the soil after germination. Wait until the buds have grown five true leaves before transplanting them into larger pots, and the potting soil should be sandy soil with good drainage.

After that, pay attention to wait for it to be stable before putting it in the sun, and usually water and fertilize it in time, and wait for fifty or sixty days for it to bloom.
