Is it okay to plant sunflowers in last year s mung bean field this year?

Yes, mung bean is a crop that requires a large amount of fertilizer, according to research, for every 100 kg of mung bean produced, it needs to absorb kg, phosphorus kg, and potassium kg. Therefore, three kinds of fertilizers of nitrogen, phosphorus and potassium are mainly applied during planting, of which nitrogen fertilizer is the main fertilizer, and the other two fertilizers are evenly matched to make it grow smoothly and improve the yield and quality.

Mung bean is a deep-rooted plant, and the cotyledons are hypertrophied, so when planting, the soil should be strictly prepared, the soil will be turned deeply, raked finely, so that the soil is in a state of pine and solid, and the depth is consistent, so as to facilitate its smooth seedling. Mung beans themselves have rhizobia, which can absorb nitrogen in a fixed manner, but they still need to apply fertilizer, otherwise the yield will be low. When fertilizing, it is necessary to follow the principle of farmhouse fertilizer and supplemented by inorganic fertilizer; mixed application of farmhouse fertilizer and inorganic fertilizer; The principle of applying sufficient basal fertilizer and timely top dressing.

Before planting, the soil should be ploughed, and then the basal fertilizer should be applied, and the basal fertilizer should be mainly human manure, grass ash, and livestock fertilizer, and 1000-3000 kg per mother. Top dressing is generally in the seedling stage and flowering stage, fertilization at the seedling stage can make the seedlings grow fast and robust, each time 10 kg of urea or high nitrogen compound fertilizer is applied per mu, and the actual situation increases or decreases accordingly. In the branching and flowering and podding stage, foliar fertilizer can be sprayed, and foliar fertilizer can be used with urea and potassium fertilizer with other elements, which can make the plant absorb as soon as possible and improve the fertilizer utilization rate.

Phosphorus fertilizer can promote the growth of mung bean plants, increase the branching and podding rate, and increase the yield, but mung bean is extremely sensitive to phosphorus fertilizer and should not be applied more each time. When applying basal fertilizer, 20-25 kg of superphosphate can be applied per mu, and it can be mixed with basal fertilizer, which can provide phosphorus throughout the growth period of the plant.

Repeated planting of beans in a plot of land will affect yields, and farmers generally rotate crops; I planted mung beans last year, and this year I planted sunflowers, not beans, so it should be okay.

Summary. No.

It is a deep-rooted crop with a large demand for fertilizer and a large growth height, which is not conducive to the lighting and growth of the lower crops.

Sunflower planting: (1) Preliminary preparation 1, land selection Sunflower has the characteristics of drought resistance, barrenness and salt resistance, general arable land and barren can be planted, but not suitable for continuous cropping, before cropping melons, wheat, cotton, beans, etc.

No. It is a deep-rooted crop with a large demand for fertilizer and a large growth height, which is not conducive to the lighting and growth of the lower crops. Aoi planting:

1) Preliminary preparation Xinhui 1, land selection Sunflower has the characteristics of drought resistance, barrenness and salinity resistance, general arable land and barren land can be planted, but it is not suitable to slip and answer continuous cropping, the previous crop balance melons, wheat, cotton, beans, etc.

Why do some say yes?

I don't think so.

Sunflower. Are you professional.

Not recommended.

Hello, red bean stubble sunflower is not good for orange Hongwei, it is not recommended to do this. Because the size and shape of the seeds of adzuki beans and sunflowers are different, and the shell of adzuki beans is harder than that of sunflowers, it is difficult to germinate. If you want to try, you can first soak the red beans for a period of time to make their shells soft and then take them out, and then mix the sunflower seed round beans and red beans evenly, put a little more mixture when planting, and bury them on the surface of the soil to keep the soil moist.

But the success rate of this method is not high. It is recommended to use specialized sunflower seeds for planting.

Hello! We're happy to answer your <>

Regarding whether it is good to grow sunflowers with red bean stubble, I think this question needs to be analyzed on a case-by-case basis. Generally speaking, it is possible to grow sunflowers with adzuki bean stubble, because this can make full use of land resources and improve the utilization rate of land. At the same time, adzuki beans and sunflowers are drought-tolerant crops that can be grown in arid environments, which can also reduce dependence on water resources.

However, it is important to note that adzuki beans and sunflowers have different growth habits, so you need to pay attention to their growth habits and growth cycles so as not to affect each other. In addition, it is also necessary to pay attention to issues such as fertilization and pest control. In general, it is feasible to grow sunflowers with adzuki bean stubble, but it needs to be analyzed and practiced on a case-by-case basis.

Off-topic extension: In agricultural production, multi-crop rotation or mixed cropping can improve the utilization rate of quiet land, reduce the occurrence of pests and diseases, and promote the restoration of soil fertility, which is a sustainable agricultural production mode.

Summary. It is okay to grow fava beans in a field of sunflowers.

It is okay to grow fava beans in a field of sunflowers.

Moreover, sunflowers will bring a lot of nutrients to the cultivation of broad beans, making broad beans grow more vigorously.

The broad bean production area in China is divided into autumn sowing area and spring sowing area, and the autumn sowing area such as southwest and the Yangtze River basin is sown in autumn and harvested in spring and summer of the following year. Broad beans in spring-sowing areas such as northwest are sown late in spring, and harvested in autumn in late silver that year. As a good precrop of rice, wheat and corn, broad bean occupies an important position in the rotation or intercropping, especially in the soil fertilization and pest control of paddy fields.

1.Temperature Sunflower is native to the tropics, but it has strong adaptability to temperature, and is a temperature-loving and cold-tolerant crop. Sunflower seeds are very resistant to low temperatures, and the local temperature is stable, and the seeds begin to germinate above 2; 4 5 times, the seed can sprout and take root; When the ground temperature reaches 8 10, it can meet the needs of seed germination.

The optimal temperature for germination is 31 37 and the maximum temperature is 38 44. Sunflowers can grow normally as long as the temperature is not lower than 10 during the whole growth process. In the appropriate temperature range, the higher the temperature, the faster the development.

2.Water Sunflower plants are tall and have many and dense leaves, making them a crop that consumes more water. It absorbs twice as much water as corn.

However, because its growth and development are mostly synchronized with local rain and heat, the contradiction between water supply and demand is not prominent. The water requirements of sunflowers vary greatly among different growth stages. From sowing to budding, it is relatively drought resistant and does not require much water, only the total water requirement.

Proper drought is conducive to root growth and enhances drought resistance. From budding to flowering, it is the peak water demand, which accounts for about 43% of the total water demand. The lack of water during this period has a great impact on production.

This stage coincides with a lot of rainfall, which can basically meet the water needs of sunflower growth and development. If it is too dry, it needs to be replenished with irrigation. It also requires more water from flowering to maturity, accounting for about 38% of the total water volume.

If the moisture is insufficient, it will not only affect the yield, but also reduce the oil content.

3.Light Sunflowers are short-day crops. But it is not very sensitive to sunlight.

For example, under the sunshine conditions of Tianjin, it can bloom and mature normally without special treatment. Sunflowers prefer full sunlight and have strong phototropism in their seedlings, leaves, and flower discs. Sufficient sunshine and strong seedlings can prevent growth; Sufficient sunshine in the middle stage of growth can promote the vigorous growth of stems and leaves, normal flowering and pollination, and improve the seed setting rate. In the later stage of growth, the sunshine is sufficient, and the seeds are full and full.

4.Soil Sunflowers are not strict on soil requirements and can grow on all kinds of soils, from fertile soils to dryland, barren and saline-alkali land.

There should be no difference in the nutrients needed for growth.
