Do not forget my cultivation method: like dry, cool environment, avoid hot and humid

It's said that today is Valentine's day. Do you want to know what you can send your girlfriend besides roses? The answer is don't forget the grass! Don't forget grass, also known as don't forget me, means eternal love and never changing heart. Don't forget me, which is cultivated by yourself, will give you more points. So what is the cultivation method of don't forget me? Let's look down together~

Don't forget my cultivation methods don't forget my basic knowledge: don't forget me (scientific name: Myosotis sylvatica), also known as don't forget grass, is a plant of don't forget grass in lithospermaceae. It is distributed in Europe, Iran, Russia, Pakistan, Kashmir, India and Chinese mainland Jiangsu, northwest, North China, Sichuan, Yunnan, northeast and other places. Don't forget I am adaptable, like dry, cool climate, avoid hot and humid, like light, drought resistant, suitable temperature for growth is 20 ℃ - 25 ℃. It is suitable for growing in loose, fertile and well drained micro alkaline soil.

Don't forget my cultivation don't forget my seedling four stages: stage one: radicle germination stage

It can germinate in 10 to 14 days at 20 ℃ to 22 ℃. The soluble salt content in the matrix was low, and the pH value was between 6.0 and 7.0. Seeds need light to germinate. Fungicide should be sprayed on the substrate before sowing. The seeds need not be covered. Keep the soil slightly moist but not excessively moist. After sowing, avoid direct sunlight and shade properly. No mulching is needed for field sowing (about 0.75g per square meter).

Stage 2: cotyledon appearance and growth stage

The temperature is between 16 ℃ and 20 ℃, which takes about 9 to 10 days. From this stage, it is necessary to reduce soil moisture properly, but not too dry. The EC Value of culture medium should not be higher than 0.5. At this stage, fertilizer can be sprayed, and 50 ppm balanced nitrogen fertilizer is suitable.

Stage 3 and 4: true leaf growth, development and seedling refining

It takes 7 to 9 days to maintain the temperature between 15 ℃ and 20 ℃. During these two stages, the fertilizer concentration can be increased to 150 ppm.

Don't forget my cultivation methods don't forget my cultivation management: 1. Transplanting: 4 to 6 weeks after germination, you can use a flowerpot about 9 cm in diameter for transplanting.

2. Substrate: the substrate should be well drained, the clay content in the substrate should be 20% to 30%, and 1 kg of fully balanced fertilizer and 0.5 to 1 kg of slow effect fertilizer should be applied to each cubic meter of substrate. The matrix should contain iron chelates and micronutrients with a pH value of 6.0 to 7.0.

3. Light: it belongs to middle sunshine plant. Don't forget that I need high light level in growing and flowering period. Lack of light and warm climate can lead to excessive stem growth.

4. Temperature: the suitable temperature for growth is 12 ℃ to 15 ℃. Under the condition of frost free in winter, the indoor or outdoor temperature can be maintained between 3 ℃ and 5 ℃. In January, the plants began to grow at 7 ℃ to 13 ℃ for 3 to 5 weeks. The growth environment should be as cold as possible, which is beneficial to improve the plant quality, but frost should be avoided to avoid frostbite. When the climate becomes warm gradually, the cold proof equipment should be removed in time to keep the cultivation environment in a ventilated state.

5. Fertilizer: the fertilizer requirement of plant is medium low. Nitrogen and potassium balanced fertilizers (n: K2O ratio of 1:1.5) were applied alternately from 100ppm to 150ppm every week. When the temperature is 5 ℃, the plant will absorb mineral elements. Too high content of ammonium and nitrogen should be avoided. Do not apply fertilizer after October. In spring, 150 ppm to 200 ppm nitrogen fertilizer can be used.

In order to prevent the deficiency of magnesium and iron, 0.025% magnesium sulfide and iron chelate can be sprayed once or twice respectively. When the temperature is lower than 10 ℃, the absorption of iron will be inhibited. Therefore, the temperature should be above 10 ℃ when spraying iron chelate.

6. It is suggested that the cold climate is beneficial to the compact plant shape. High relative humidity and too wet leaves easily lead to the reproduction of gray mold. When cultivated, keep it slightly wet, but not too wet.
