The characteristics of the pollution-free characteristics of amaranth are more developed, the roots of the amaranth are more developed, and the roots are weaker and white, which is not suitable for transplanting. During the vegetative growth period, the stems are shortened, and the leaves are born on the shortened stems. Leaves clumped, green or light, leaves puberulent, pinnately lobed or lobed. The seeds are small, oval, golden yellow, and have a longer dormancy period after the seeds mature. Amaranth is cold-tolerant and grows well in cold climates. The seed germination temperature is 20 ° C ~ 25 ° C, the vegetative growth temperature is 12 ° C ~ 20 ° C, the temperature is about 15 ° C, the growth rate is fast, about 30 days after sowing can be harvested; the temperature is lower than 10 ° C, the growth is slow, It can be harvested about 45 days after sowing; the temperature is above 22 °C, not only slow growth, but also poor quality. Amaranth can tolerate a short-term low temperature of -7.5 ° C, and plants below freezing below -5 ° C. Seeds or seedlings of amaranth sprouting can pass through the vernalization stage for 10 to 20 days under low temperature conditions of 2 °C to 5 °C, and can be twitched and flowered under 12 hours of light and temperature of about 12 °C. Amaranth has high requirements for soil fertility and water. It is planted on fertile, loose, water-preserving and fertile soil. The leaves of leek are fertile, with high yield and good quality. Amaranth pollution-free varieties 1. Currently produced on the cultivation of amaranth, there are varieties such as eucalyptus. The plant has about 18 leaves. The leaves are pale green, the leaf margins are pinnately nicked, and the leaves are slightly hairy; the leaves turn deep after the low temperature is felt. Amaranthus chinensis has strong cold resistance and heat resistance, rapid growth, early maturity and high yield, and the growth period is about 40 days. Because the blade is large and has a good appearance, it is welcomed by the market. However, the winter is weak, and the spring cultivation of ticks blooms earlier. 2. Amaranth is also known as small leaf leeks or broken leaf leeks. The leaves are narrow, short, and grow up in the ground. The adult plants have about 20 leaves. The leaves are green, the leaf margins are pinnately deep, and the leaf surface is more hairy; after the low temperature is felt, the leaf color is deepened and purple. The cold resistance is slightly weaker than that of the leaf amaranth, while the heat resistance and drought resistance are strong, and the winter is also strong. Spring cultivation is late, the growth period is about 40 days, suitable for spring cultivation; the leaves are soft, the fiber is less, and the aroma is stronger.
