Efficient management technology of eggplant transplanting period

  In the process of planting eggplants in the shed, no matter whether it is a warm shed or an arch shed, it often encounters problems of light and temperature treatment in cultivation, and there are also misunderstandings in using good fertilizer water. Combining the experience of experts in eggplant cultivation areas and the experience of large-scale cultivation, it is now suggested that the broad-growing households, sheds eggplants: pay attention to the light temperature and use "water".

As we all know, eggplant is not cold-tolerant, and requires high temperature and light conditions during growth and development. Therefore, winter-planted eggplant requires good equipment in the greenhouse, high soil fertility, and strict technical requirements for cultivation skills, as long as it can handle high yields. , high quality and efficient.

    The shed aubergine requires suitable "microclimate" conditions. The suitable room temperature for seed germination is 25-30 ° C and the low temperature is 11-18 ° C. The suitable temperature for flower bud differentiation at seedling stage is 20-25 ° C in day and 15-20 ° C in night. . In the range of suitable temperature, the flower bud differentiation is delayed when the temperature is slightly lower, but the long flowering column is more, the seed setting rate is high, and the production value is high. The flowering result period requires a suitable temperature of 25-30 ° C. If the temperature is lower than 20 ° C, it will hinder the normal flowering pollination and affect the growth and expansion of the eggplant.

    Eggplant is hi-light, the leaf evaporation is large, and it is not resistant to drought, but it requires air to be boring. If it does not let the wind for a long time, it will form fruit decay and disease.

    In the process of handling shed eggplant, the following management methods should be adopted in conjunction with climatic conditions.

    First, strengthen the indoor temperature management of the shed:

    Before the flowering result, try to adhere to the temperature of 15-20 °C as much as possible, and promote the flower buds to form a makeup flower column, and improve the seed setting rate. After the flowering result, pay attention to the temperature in the shed, especially pay attention to the ground temperature, it is best to adhere to above 20 °C, the minimum must be above 15 °C, the temperature can be improved by 2-3 °C, to ensure that the night temperature is appropriate. After sprinkling water, in order to adhere to the ground temperature, it is necessary to make the shed temperature warm. When the temperature progresses, increase the ventilation and ventilation, sweep away the humid air in the shed, adhere to the boring air in the shed, and reduce the incidence of solana.

    Second, strengthen the management of fertilizer and water for different growth time of eggplant:

    Because the eggplant needs less water in the early stage, basically no need to sprinkle water. However, it is still necessary to use fertilizer water (organic humic acid fertilizer) for root irrigation. In the result period, the amount of water required is large, and the number of watering should be appropriately added. The lack of water will form a small fruit, and the base of the tomato stem has no luster, which affects the output value and quality of the solanaceous fruit.

    Third, the eggplant flowering period must be controlled by light and temperature conditions:

    Adhere to the appropriate temperature in the shed and the stability of the ground temperature, timely remove the old leaves and side branches, and often clean the shed surface, adhere to clean and light, promote fruit growth and color, timely harvest and sale.

    Fourth, eggplant from the colonization to slow seedlings, fruit, should master the "small fertilizer water roots, medium fertilizer water to promote seedlings, big fertilizer water to raise fruit" guidelines.

    That is to say, the rooting period of seedling is 500-800 times of organic active liquid fertilizer, 100-200 ml per plant. The growth time of the strong seedlings should not be too large, to avoid the soil permeability of the Wenwen soil. The biological fertilizer should be selected for flushing and the method of interlacing water should be adopted.
