Can you grow quinoa in Fuyang, Anhui?

Quinoa can be planted in Fuyang, Anhui Province, but it is not suitable. The high climate and low altitude in this area are not conducive to the growth of quinoa.

Analysis and explanation:

Fuyang area is located in the southern margin of warm temperate zone, which belongs to semi-humid monsoon climate. The monsoon is obvious, the four seasons are distinct, the climate is mild and the rainfall is moderate.

The altitude of Fuyang area is17.5 ~105m. The summer high temperature in Fuyang reaches about 45 degrees Celsius, the annual average temperature is about 15 degrees Celsius, and the frost-free period is 220 days.

The growth period of quinoa is 90-220 days, and the local frost-free period should be above 100 days, the altitude should be above 1500m, the precipitation should be above 300mm, and the maximum temperature should not be higher than 32 degrees.

So this area can be planted, but the climate and altitude are not conducive to growth.

Preparation before broadcast:

The sowing date should be determined according to the local climatic conditions, base fertilizer application and soil preparation. It is best to spread fertilizer (organic or inorganic or mixed) evenly on the ground one week before sowing. Rotary tillage land15-20cm deep. If there are roots or plastic films left by previous crops in the field, they should be thoroughly cleaned up to avoid affecting sowing and the growth of quinoa.

It is suggested that the amount of base fertilizer should be determined according to soil test. If the soil is poor and there is no soil testing condition, 40-45 kg of sulfur-based compound fertilizer should be applied per mu (the ratio of nitrogen, phosphorus and potassium in compound fertilizer should reach15:15 or higher).

Training points:

The seed dosage per mu is 400g, the row spacing is controlled at 45-50cm, and the sowing depth is1-2cm.

Pay close attention to the growth of buds or seedlings and the situation of underground pests within 3- 10 days after sowing. If the underground pests are serious, it is necessary to consider secondary sowing.

Seed dressing materials, such as millet or millet, need to be prepared before sowing. If it is necessary to stir-fry millet in advance, the ratio of seed to seed dressing material is 1 seed and 2 millet (millet), or the amount of sowing material is determined according to the debugging situation to ensure the sowing quantity and uniformity.

On-site management:

It is suggested that the base fertilizer should be completely applied at one time without topdressing. If the symptoms of fertilizer deficiency are found in the late growth stage, the topdressing nitrogen fertilizer should not exceed 15 kg per mu.

Mainly in dry farming, underground pests are the main pests in the planting process of quinoa, among which scarab is the most serious pest. Newly germinated or unearthed quinoa seedlings are vulnerable to all kinds of underground pests, which will lead to complete extinction in severe cases. Therefore, it is necessary to know the situation of underground pests in this plot before sowing. If the underground pests are serious, it is necessary to sprinkle pesticides to kill the underground pests when sowing.

Other common pests are coriander. When quinoa grows to more than 50 cm, it begins to damage leaves or inflorescences. Coriander is relatively concentrated and often gathers on several quinoa plants. The easiest way is to observe coriander and catch it manually.

When the seedling of Chenopodium album grows to 10 cm, it can be hoed for the first time in combination with thinning. Generally, when the seedling of Chenopodium album grows to more than 50 cm, it needs to be hoed 1-2 times.

Thistle seedlings 10 cm can start thinning, and the spacing between plants is about 25 cm.

Since the height of quinoa can reach more than 2 meters, the roots should be cultivated consciously from the second weeding to make the roots more stable and prevent lodging in the later stage.

If incomplete seedlings are found after emergence, the seedlings can be dug and transplanted when they grow to 15-20 cm, and the transplanting should be carried out after rain or with water supply.

Harvest:

The standard of maturity of quinoa is to look outside, the leaves turn yellow and red, most of them fall off, the stems begin to dry, the seeds are pinched with nails, and there is no water.
