Matters needing attention in planting quinoa

Chenopodium is a plant of the genus Chenopodiaceae. It is a traditional staple food of Indians. The plant is similar to gray vegetables in shape, and the spike is similar to sorghum ear after maturity. The seeds are edible and have high nutritional value. The following is to introduce the matters needing attention in the planting of quinoa.

1. Select the place

Quinoa is native to Colombia, Ecuador, Peru and other medium-and high-altitude mountains in the Andes of South America. It grows from sea level to plateaus about 4500 meters above sea level. The most suitable height is 3000-4000 meters above sea level or in mountainous areas. You can choose plots with higher topography, sufficient sunshine, good ventilation and good fertility. It should be noted that quinoa should not be replanted and continuous cropping should be avoided.

2. Land preparation

When the soil just thawed in early spring, apply sufficient base fertilizer, generally 1000-2000 kg of rotten farm manure and 20-30 kg of potassium sulfate compound fertilizer per mu (667m2 / mu). If the soil is barren, the application amount of compound fertilizer can be increased appropriately. Rake every time it rakes before sowing, so that it is empty and solid, only rake without ploughing in case of drought, and compaction treatment is carried out.

3. Sowing seeds

Generally sowing in the middle of May, when the temperature is 15-20 ℃, sowing with millet precision seeder, the row spacing is about 50 cm, the plant spacing is 15-25 cm, and the sowing depth is 1-2 cm. Check seedlings in time after emergence, and replant seedlings in time when missing or missing seedlings. When seedlings grow to 10 cm and grow 5-6 leaf time seedlings, according to the principle of keeping large to small, the plant spacing is kept at 15-25 cm.

4. Field management

(1) Intermediate ploughing: in combination with inter-seedling, we should master shallow hoe, fine hoe, broken soil, surround the seedlings, achieve the same depth, clean the grass and level the ground, so as to prevent the seedlings from being injured and pressed. In case of heavy rain after ploughing, the hardening should be broken when the topsoil dries slightly after the rain.

(2) weeding: when quinoa grows to more than 50 cm, weeds need to be weeded 1-2 times; at the age of 8 leaves, weeds, diseased plants and residual plants will be pulled out to improve uniformity, ventilation and light penetration.

(3) topdressing: if the symptoms of fertilizer deficiency are found in the middle and later stage of growth, topdressing can be appropriate. Generally, when the plant grows to 40-50 cm, 10 kg of ternary compound fertilizer is applied per mu; in the late growth stage of quinoa, foliar spraying of phosphate fertilizer and trace element fertilizer can promote flowering and fruiting and grain filling.

(4) watering: quinoa has a certain drought tolerance, mainly dry farming, if there is a serious drought, it should be watered in time.
