How to Control the Growth Environment of Potted Lemon
Lemon is Rutaceae Citrus evergreen small tree. The leaves are small, long oval, and the leaves are serrated. Flowers are solitary, open throughout the year, and full of aromas. The fruit is oval or oval in shape and matures in autumn and winter. The skin is yellow, the fruit is very sour and aroma, the juice is citric acid, and the peel can be used to extract lemon oil. Lemon is mainly used for juicing, and sometimes it is also used as a cooking seasoning, but it is basically not used as a fresh food. Rich in vitamin C. The lemon pot technology mainly includes the following points:
Nursery and upper basin: large amount of cultivation in the south, suitable for grafting and breeding; northern cultivation is less, mainly with cutting methods, can also buy grafted seedlings. The root system of lemon has higher requirements for water, nutrients and soil. Potted soil should be made into water-permeable, water-reserve, fertilizer-saving and slightly acidic culture soil. Upper basin and basin change time, autumn, early spring can be, according to local climate flexibility.
Light and temperature: Lemon is a light plant. However, if the sunlight is too strong, the growth and development are not good. The average annual temperature at which the plants are to be replaced at an average of noon is above 15°C. The optimal growth temperature is from 23°C to 29°C. Growth is stopped at more than 35°C, and freezing at -2°C. Lemon generally does not need to cool down in summer, enter the room before the frost, after the Qingming out of the room, you can safely winter. Temperature control, we can use the temperature and humidity self-recording device, that is, self-reporting temperature and humidity meter. Self-recording thermometer and hygrometer is an instrument that can measure temperature in time. It is a kind of recorder and has a good function of recording temperature and humidity. In addition, we can use the field microclimate automatic observer to measure the light. This field micro-climate automatic observer has a light sensor, so it can measure the light intensity. In addition, it can also determine other parameters such as soil moisture, soil temperature, dew point, wind speed and other wind direction.
Watering and fertilizing: Lemon needs more water in growth and development, but too much water is not easy to rot. In general, the spring is the time for drawing leaves and buds to bloom, and water should be applied in proper amounts. In summer, the light is strong, the temperature is high, and more water is needed. However, timely and appropriate, otherwise it will cause a drop. The fall is the growth of autumn shoots, the rapid expansion of the fruit, and must have sufficient moisture. Late autumn and winter are the flower bud differentiation period, basin soil will be partial dry. Lemon is more like fertilizer, in addition to the basin, Shipenshi base fertilizer, the growth period should adhere to the principle of thin fertilizer. The frequency of fertilization and the amount of fertilization must be determined by the growing season and the phenophase. For example, the application of liquid fertilizer to fully fermented cakes and water is better, the cake to water ratio is 1:200. The northern soil is slightly alkaline, and ferrous sulfate can be added to the fertilizer solution to form a slightly acidic nutrient solution.
