Early Spring Vegetable Seedlings
Increase the use of farmyard manure when growing vegetable manure, especially hot fertilizer, can not only cultivate fertility, cultivate strong seedlings, improve the disease resistance of vegetable seedlings, prevent roots, but also increase the temperature. Specific approach: before the vegetable nursery, fully cooked hot farmyard mash and bed soil mix. Keep the temperature at night and cover the straw and keep it warm and cold, and control the temperature inside the bowl according to the type and time of different vegetables. Such as: cucumbers, melons and other melons can not be lower than the temperature requirements of 12 °C, eggplant, pepper and other eggplant requirements can not be less than 10 °C. The temperature in the bowl after sowing and before emergence should be as high as possible; after emergence, the temperature should gradually decrease before the seedlings are divided; after the seedlings, the temperature difference between day and night should be appropriately increased according to the characteristics of the vegetables. Ten days before colonization, the seedlings must be cultivated. In order to prevent root cause by the low ground temperature, it is better for the conditional growers to use electric hotbeds to raise seedlings in the shed to facilitate insulation. Timely dehumidification in the protection of seedlings nursery, the general seedbed is not obvious drought (above the surface of the group does not scattered groups) when not watering; obvious drought when the amount of watering should not be too large. Before increasing the light to raise seedlings, the seedbed should be selected in places with sufficient sunlight, which is conducive to the robust growth and development of seedlings, enhances their resistance to diseases, and reduces the occurrence or spread of roots in the seedlings of vegetables. Prompt ventilation After the cotyledons were unfolded, select clear and warm weather to open the cover for ventilation, and evenly spread a layer of fine dry soil to the seedbed, and then cover the cover tightly.
