Strawberry nursery should be reasonably shaded
To cultivate strawberry seedlings, it is necessary to understand the habits of strawberries that are cool and insensitive to high temperatures and droughts. If the summer is poorly managed, the plants will suffer serious physiological disorders and even cause massive deaths. The main measures for the management of strawberry over the summer are as follows: Reasonable shade. In the summertime, the temperature in Jianghan Plain is high. If no measures are taken to shade the strawberry seedlings, most of the strawberry seedlings will die because they are not resistant to high temperatures. Generally concentrated nursery should take a 1 meter high awning on the surface of the sorghum and cover it with a silver shading net with a shading rate of 85%. During the high temperature period (with a maximum temperature of 30°C or more), it is covered daily from 9:00 am to 5:00 pm, and the temperature is 30°C. The following sunny days and cloudy days before 9 o'clock in the morning will not be covered after 5 o'clock in the evening. Farmers can raise seedlings in a small area and can grow maize at intervals of 2 to 2.5 meters to allow the corn seedlings to shade the strawberry seedlings and prevent them from burning at high temperatures. Scientific irrigation and drainage. Most of strawberry roots are located in the topsoil layer and require high water content and avoid drought. In the Jianghan Plain, the humidity in the field changed greatly during the summer, and it was easy to accumulate water in the event of heavy rain and heavy rain. The growth of the roots was hindered, and it was not raining for a week. The phenomenon of water shortage and drought appeared in the strawberry seedlings. Therefore, the ditches and drains should be cleaned and the ditches should be maintained. , to achieve drainage and irrigation combined. Irrigate in time when drought occurs, and drain water in time when it rains, so that the rain stops. For concentrated nursery, shade nets should be covered before heavy rain to make heavy rains lighter and reduce the adverse effects of heavy rain on strawberry seedlings. In high temperature and drought, sprinkler irrigation or watering on the shade net can be turned on, which not only supplements the water, but also It is conducive to cooling, more conducive to the growth of strawberry seedlings. Weeding and old leaves. The strawberry seedbed is dominated by manual weeding. Do not loosen the strawberry roots during weeding to avoid the death of the strawberry seedlings. In addition, yellow leaves, dead leaves and diseased leaves of strawberries should be promptly removed to reduce nutrient consumption and water evaporation, and improve ventilation and light transmission conditions. Directional pressure vines, pendulum. The strawberry nursery used for the propagation of seedlings should be able to straighten the stems and stems in the same direction at the seedling stage in order to be able to breed a proper amount of strong seedlings. A small ditch is excavated every 20 cm, and the ditch is evenly filled with 1512 cm of nutritious soil. For nutrition, introduce the new strain into the nutrition bowl and press it slightly with the soil to promote new roots.
