Friends who bought a thousand red flowers, they must think that it is very delicate, and it will become a pile of weeds. In fact, many people do not understand the breeding technology of amaranth, and then let Xiaobian take you to grow the cultured flowers. Knowledge.
Cultivation technique of amaranth
Amaranth is not strict with the environment, but it is sunny, hot and dry, suitable for loose, fertile and well-drained soil. The seedlings are relatively robust, and the seedling trays that are denser at the time of sowing can be placed on the pot after a transplant, or they can be broadcasted to the trays, and the pots are 4 to 6 weeks after emergence. Use a 10 to 14 cm diameter basin. The potting soil is mainly grass charcoal, and the proportion of garden soil is preferably less than 15%. It is also feasible to use the soilless medium completely.
Amaranth flowers were positive, except seedling stage, not in direct sunlight, the basin after 2 to 3 weeks can be grown in a sunny environment. The light is sufficient to form a round and low plant shape. During the cultivation process, it is necessary to maintain sufficient plant spacing to avoid mutual crowding, lack of light and poor plant shape.
Hi warm, sunny, strong, suitable for loose, fertile and well-drained soil. The growth of amaranth is strong, the requirements for fertilizer and water are not strict, and the management is simple. Generally, the planting period is applied once or twice to the light liquid fertilizer. During the growth period, it is not suitable to water and fertilize too much. Otherwise, the stems and leaves will be long and the flowering will be scarce. Amaranth grows in a warm season, and fertilization should not be much. Generally, a thin fertilizer is applied once every 8~0 days, and it is carried out in the same way as watering. 1 gram of fertilizer is added per liter of water, and the compound fertilizer with NPK-mg of 1.0-0.5-2.O-0.3 is good, and the soil pH is 6.0. The EC value is controlled between 0.8 and 1.2. Plants can increase phosphorus and potassium levels in the later stages of growth, and the EC value can be slightly higher, at 1.6. During the growth period, timely irrigation and cultivating should be carried out to keep the soil moist. The rainy season should be drained in time. At the flowering stage, the liquid fertilizer rich in phosphorus and potassium is applied twice to three times, and the flowers are leafy and colorful. After the residual flowers, don't let it seed, can be plasticized and pruned, still sprout new branches, and bloom again in late autumn.
Thousands of red branches are born in leafhoppers. In order to promote the low planting, branching and flowering, the seedlings should be pruned several times during the seedling stage.
The center of the cultivation and management of amaranth is to cultivate a good plant shape, and it is better to maintain the sun, use the dwarf and negative DIF values ​​(the temperature is reduced by 2~3 °C).
This flower is heat-resistant, but it is not cold-resistant and cannot withstand frost.
Be kept moist after potting a potent red pot and pay attention to shading. The growth period is combined with watering for top dressing. This flower is not strict with fertilizer and water, and the management can be more extensive. After the residual flowers are pruned, the new branches can still be germinated and bloom again in late autumn, but more fertilizer should be applied.
Amaranth is native to China and India. It is not strict with the environment, but it is sunny, hot and dry, suitable for loose, fertile and well-drained soil.
