Fengxian flowers, such as crane top and colorful Phoenix, are graceful and charming. They are often cultivated and cultivated for appreciation. Let's learn about the cultivation methods of Impatiens.
The cultivation method of garden Impatiens I. ground planting:
1. Land selection and preparation: the soil with sufficient sunshine, moist soil, fertile, loose and good drainage is suitable. Apply base fertilizer, prepare land for border, make high border in the south, and make flat border in the north, with border width of 1.2m.
2. Sowing time: Impatiens can be sown from March to April, directly in the open seedbed in the south, in the greenhouse or inter bed in the north, once transplanted, and can be planted at the end of May. Impatiens is a kind of spring sown grass flower. If sown in late July, it can be seen on national day.
3. Sowing method: open a shallow ditch of LCM with a row spacing of 35cm, evenly sprinkle the seeds into the ditch, cover the soil, press down slightly, and then water. After sowing, the soil was kept moist, and the seedlings began to emerge about 5 days when the temperature was about 25 ℃. The amount of seed used per 667 square meters is 500g.
4. Transplanting and planting: pour enough water before transplanting, and then transplant with soil lump. When transplanting, the planting depth should be the original depth or a little deeper. When the height of the seedlings is 5-10cm, they should be transplanted and planted. The small, thin and dense seedlings should be removed and fixed according to the plant spacing of 20cm. Reasonable close planting can produce high quality and high yield.
2、 Potted:
1. Basin selection: the size of the basin shall be 30cm ~ 50cm in diameter and 35cm ~ 55cm in height. The bottom of the basin shall be padded with broken tiles to facilitate drainage.
2. Potting: when the seedlings are 7-8 cm high, they can be potted. The basin soil is made up of 1 part garden soil, 1 part sand soil, 0.5 part rotten leaf soil or rotten rice husk, 0.5 part base fertilizer, and the bottom of the basin is padded with broken tiles to facilitate drainage. After watering, put it in the shade of ventilation, and move it to the sunny place after 3-5 days.
3、 Maintenance skills
1. Light and temperature: good at light and shade. Receive at least 4 hours of scattered sunlight every day. Shade in summer to prevent excessive temperature and sun exposure. The suitable growth temperature is 16-26 ℃, and the environmental temperature at flowering stage should be controlled above 10 ℃. Enter the greenhouse in winter to prevent freezing.
2. Watering and fertilizing: water should be poured in time after planting. Pay attention to watering during the growth period, and keep the basin soil moist frequently, especially in summer, but do not allow water accumulation and soil over wet for a long time. If there is more rain, pay attention to drainage and waterlogging prevention, otherwise the roots and stems are easy to rot. After planting, fertilization should be done frequently, and special attention should be paid not to dry or wet. Do not water wilting plants in the hot sun in summer. Especially in flowering stage, it is not allowed to suffer from drought, otherwise it is easy to fall.
3. Pruning: after planting, the main stem of the plant should be topped to enhance its branching ability; the base flowering should be picked at any time, so as to promote the top of each branch to blossom in succession.
4. Prevention of diseases and insect pests: powdery mildew is common; it damages the leaves, flowers, fruits and other organs of plants. There is no obvious disease spot in the diseased part, but if it is covered with powdery mildew, there will be small black spots. Control methods: spray 70% tolbutine 1000 fold solution or 50% carbendazim 1000 fold solution at the beginning of the disease.
5. Management: in order to prevent weeds from seizing water, loosen soil and weed timely, and water timely in case of drought. When the seedling height of Impatiens is 30-40 cm, the old leaves at the lower part of the stem should be removed in time, and the top of the leaves can be removed to make it more branched. The application of cake fertilizer 40kg per mu of Impatiens, the fertilizer will be sprinkled in the ditch, and timely watering, is conducive to the flowering of Impatiens.
Attention should be paid to the ventilation of potted impatiens. If the ventilation is not good, the neck of Impatiens will rot. Pay attention to the high temperature and light. If the temperature is too high and the light is too strong, the blade will be burned. Therefore, shade ventilation, water spray and other cooling measures should be taken. In winter, it is better to put it in the place of heat preservation and sunshine without passing the shade (the room temperature shall be kept above 13 ℃). During the growth period, it should be dry and wet, and keep the basin soil moist; however, it is not allowed to accumulate water in the basin, otherwise, it is easy to rot roots and rotten stems, and finally lead to death. When the air is dry in midsummer, it should be watered in time, but not too wet. At the same time, water should be often sprayed around the leaves and basins to increase the air humidity, pay attention to ventilation, improve the growth environment, and make the leaves of Impatiens green and flowers bright. The watering should be reduced gradually in autumn and the basin soil should be kept slightly wet in winter.
