1:Water amaranth is an aquatic weed, seed germination requires high water, germination is better when the soil is supersaturated with water or when there is thin water, germination is less in wet condition, and it does not germinate under drought conditions, so the period of occurrence is late.

2:Because the seed is small, can only shallow germination, the starting temperature of germination is 16 ° C, but the low temperature when the germination is slower, the average temperature of 20 ° C or more germination is better, the occurrence of a long period of time, rice throughout the reproductive period can occur.

3:Nutritional growth of water amaranth grows better in shallow water, the growth of wet state is poor, in long-term wet conditions, plant growth dwarf, not branching, water amaranth shade tolerance, intolerance of strong light irradiation, preferring to be born in the paddy field. But still require more adequate light, in the rice sealing line before the occurrence of water amaranth growth is better, rice growth in the after 9 occurrence of water amaranth, because too much shade, the growth of more weak, dwarf. Ear leaf water amaranth, multi-flowered water amaranth and rice relative height of up to 0.8 or more occurred in the front.

4: "real water harebell belongs to the short sunshine plants, paddy fields, flowering August-October, fruiting in 90 months, in the rice in the middle and late occurrence of water amaranth, shade in the rice rows can still be open fruiting, but the amount of fruiting is less.

If useful, hope to adopt!
