How to choose quinoa seeds? What are the methods of raising seedlings?

In fact, many friends do not know what kind of plant quinoa rice is. Quinoa is native to Colombia, Ecuador, Peru and other medium-and high-altitude mountains in the Andes of South America. It is rich in vitamins, polyphenols, flavonoids, saponins and phytosterols with a variety of health effects.

First, how to select quinoa seeds?

1. Longli No.1

(conventional) quinoa varieties. The apical leaf bud is purple in the inflorescence stage, the stem is red in the mature stage, the plant is broomlike, the plant height is 181.2-223.6 cm, the inflorescence, the main shoot and lateral branches are seeded and self-pollinated.

two。 Longli No.2

(conventional) quinoa varieties. At the heading stage, the apical leaf bud was green, the plant was broomlike, the plant height was 198.0cm, the inflorescence, the main shoot and lateral branches were seeded, and self-pollinated; the seed was round tablet-shaped, 1.6-2.4 mm in diameter, 2.94-3.32 g in 1000-grain weight, 16.51% in crude protein, 5.2% in fat, 3.42% in crude ash, 7.0% in lysine and 0.56% in total phosphorus.

3. Longli No. 3

(conventional) quinoa varieties. The plant is broomlike, the stem and ear are golden at maturity, the plant height is 110.4-162.7 cm, inflorescence, main shoot and lateral branches are seeded, self-pollination The seeds are brownish yellow, round tablets, 1.4mm in diameter, 2.26mm in weight, 2.72g in weight, 16.69% in crude protein, 6.02% in crude fat, 0.33% in crude ash, 0.64% in lysine and 0.66% in total phosphorus; the growth period is 96 to 116 days.

2. Seedling raising methods of quinoa

1. Land selection and preparation

Chenopodium has a strong ability to adapt to the soil, but if you want to grow high-yielding quinoa, you still need to choose the plot with sunny leeward, strong permeability, fertile soil and good drainage and irrigation. Planting quinoa must not be continuous cropping, otherwise there will be all kinds of diseases and insect pests and weeds. The grain of quinoa is relatively small, and the ability of the top soil of the seed is poor, so it is necessary to do a good job in soil preparation, check whether there are residues of previous crops in the soil and clean up in time. After soil preparation, the base fertilizer can be fully applied, and the base fertilizer can use fully mature farm manure or "fertile leaf microbial agent" to improve soil fertility and promote the germination and emergence of quinoa seeds.

two。 Sowing at the right time

When sowing, you should choose the right time, not too early and too late. Sowing in the south should choose the end of spring. If the sowing is too early, the temperature is lower, it is easy to restrain seed germination, and the seedlings may suffer from cold injury in spring. Sowing too late will delay the harvest of quinoa, and the seedlings may be unable to grow due to excessive summer temperatures. When sowing, pay attention to soil moisture, according to the soil moisture to control the sowing depth, through the deep and shallow will have a certain impact on the growth of quinoa. The depth of sowing should not exceed 3 quinoa, more than 3 cm, the seeds can not emerge from the top of the soil, but too shallow sowing will aggravate the lodging phenomenon of quinoa.

3. Check the seedlings between seedlings

After successful seedling emergence after sowing, seedling inspection should be done well, and seedlings should be replenished in time to ensure the yield of quinoa. When the seedlings grow to about 15 cm, the seedlings should be properly separated to ensure that each quinoa has sufficient growth space, which can increase the number of remaining seedlings and ensure that the seedlings are in the state of the whole seedling. In the seedling stage of quinoa, weeds should be prevented. Proper weeding is beneficial to the growth of seedlings and ensure adequate nutrition. In the later stage, according to the growth of quinoa, the soil was cultivated in time, and when the height of quinoa reached the thigh, weeding was carried out again to prevent the nutrition needed for quinoa growth.

4. Timely harvest

Harvest time also has certain requirements, we should be based on quinoa plants and wheat grains, when quinoa mature, grain ears completely yellow, leaves withered yellow fall. The wheat is full and hard and can be harvested at this time. Harvest time should not be too late and too early, early harvest, wheat grain is not fully mature, easy to mildew, resulting in a decline in yield. If the harvest is too late, it is easy to lodge, and a large number of wheat grains fall into the wheat field, resulting in serious damage to yield and quality. Avoid overcast and rainy weather when harvesting, wheat grains are not easy to store in case of water, and are easy to cause diseases and insect pests.

To sum up, it is the introduction of quinoa. If you also want to seed quinoa, please be sure to consider whether it can be planted locally, because the planting conditions of quinoa are relatively strict.
