The following editor has brought you the breeding method of thousand-day red, let's have a look!

1. Methods of reproduction

The propagation methods of Qianrihong are mainly sowing propagation and cutting propagation. Before sowing and breeding, first soak the seeds in warm water for a day or so, and then mix the plant ash, which can be broadcast directly. Then choose the left and right seedbed with sufficient light, normal drainage and irrigation, soft soil and high fertility. Cover the soil after sowing, the temperature is controlled at about 22 degrees, and the seedlings can emerge after about half a month. After the emergence of seedlings, it is necessary to do a good job of interseedling work, and then watering urea and spraying foliar fertilizer. Cutting propagation in June to choose about 5 cm long robust at least, retain about 3 nodes, directly inserted into the sand bed, the temperature is also about 22 degrees, about three weeks can be transplanted.

2. Water and fertilizer management

Thousand Ribbon has a large demand for fertilizer. Therefore, when the seeds are red for a thousand days, we should not only apply sufficient knots when planting. When it enters the peak growth period, it should also be fattened every two weeks or so. The main fertilizer is rarefied liquid fertilizer, in which the proportion of phosphorus and potassium fertilizer should be increased appropriately. And thousand-day red also likes to grow in slightly moist, slightly dry soil, there is a certain degree of drought tolerance. Therefore, after growing new leaves, we should pay attention to reduce the amount of water. To the thousand-day safflower bud differentiation, and then appropriately increase the amount of water to ensure the flowering rate and flower quality.

3. Daily management

Thousand-day red in the growth process, is the need for sufficient light. So we should pay attention to control the light, in which at least 4 hours of light time should be maintained every day. The shade of the breeding ground should not be too large, otherwise it will hinder the growth of thousand-day red, reduce the quality of flowers, and the color of flowers will become dim. Then we also need to do a good job in the prevention and control of diseases and insect pests, especially in the thousand-day red seedling stage, it is very easy to appear blight, which will have a great impact on the growth of thousand-day red, and in serious cases it will lead to death, so we must strengthen management and reduce the incidence of diseases.

4. Florescence plastic surgery

When the seedlings of Qianrihong grow to about 15 cm high, it is necessary to pick the heart and increase the number of branches. Then pick the heart again according to the actual growth of thousand-day red. In plastic surgery, it is best to find a circle for thousand red plastic surgery, to improve the ornamental value of thousand red. After shaping and shaping the plant, and then do a good job of coring the branches, we can achieve the purpose of controlling the flowering period. After entering the flowering stage, the soil should be kept in a slightly wet state, not to let the flowers touch the water, but also not to fertilize, to provide normal light. The pedicel should be pruned after flowering to increase the flowering rate in the second year.

The above is a brief introduction to the breeding method of thousand-day red. That's all for today's introduction. This article is for reference only. I hope it can help you all.
