The nutrient solution is very important for the hydroponics of Brassica. It is recommended to prepare acid nutrient solution containing nitrate nitrogen. After the planting of Brassica, the diluted nutrient solution should be used immediately. The nutrient solution should be poured through, and the exuded nutrient solution can be seen at the bottom of the basin, which is the state of pouring through. In addition, it is suggested that you can spray some aqueous potassium dihydrogen phosphate solution on the leaves of seedlings to help the growth of seedlings. In addition, timely supplement of nutrient solution and water is also very important to prevent excessive salt content in the substrate. When there is frost on the surface of ceramsite, it is recommended to clean the salt in the cultivation substrate.
Just planted seedlings, placed in a darker place for slow seedling, after the normal growth of seedlings, you can move to a place with sufficient light. In addition, Brazilians like sunshine. In addition to summer, they can keep sufficient sunshine in other seasons. In summer, they should be prepared for shade to prevent Brazilians from being exposed to direct sunlight. In winter, we should pay more attention to the sufficient light. In addition, Brazilian wood likes to be warm. In winter, we should ensure that the room temperature is above 10 ℃, so that Brazilian wood can grow better and spend the winter safely.
When the indoor air is too dry, the leaves of Brassica will curl. When this happens, you can choose to spray water around or put a water basin to increase the air humidity. In addition, when the plant is too high, the top part of the trunk should be pruned in time, so as to sprout new shoots, which is more suitable for the appearance of Brassica, so that people can enjoy and watch.
