Greenhouse eggplant seedling technology

Fear dried eggplant seedlings, seedbed soil garden soil culture proportion slightly greater than the cucumber and tomato, i.e. garden soil 6 parts, 4 parts of compost, manure composting 1 parts, per cubic meter of nitrogen was added 100 grams, 200 phosphate Gram, 100 grams of potassium fertilizer , and should be mixed and accumulated one month before sowing. The bottom water before sowing should also be larger than the tomato. Some places are sown with a seed box, which can be placed on the warm ground near the fire. The solar greenhouse should also be in the best temperature and light conditions, which is beneficial to the high temperature demand of eggplant. The place where the seedlings are divided twice can be carried out for the first time after the two true leaves are unfolded, roughly 25 days after sowing , and the row spacing is 10 cm × 10 cm. It was before the first flower differentiation. The second seedling should be carried out 20 to 25 days after the first seedling, and the seedlings are grown after 4 true leaves. This time, the seedlings, planned to be planted in the greenhouse, one can be divided into greenhouses from the greenhouse to the greenhouse, so the training of the seedlings is more important, the beginning of the week before the start of large ventilation, especially the night temperature down, maintain 13 ~ 15 °C, and should be consistent in step, grasp the progress, do not let the seedlings freeze in the open air, it is best to seed the seedlings on a sunny day. Immediately transferred into the greenhouse covered with a small shed, night be stamped mats, and which surrounds the cover around 5-6 days to Huanmiao. If a third seedling is needed, it can be carried out 25 days after the second seedling to further increase the nutrient area. The greenhouse eggplant colonization is a large seedling of 10 to 12 true leaves, and the management of the seedling stage is crucial.

In order to bred the ideal seedlings, the temperature of the seedbed can be gradually reduced, from 28 to 30 °C to 23 to 25 °C, and gradually drop to 13 to 14 °C at night . The night temperature has a great influence on the quality of the flowers. Excessive nighttime temperature often deteriorates the flower quality, and the flowering is increased, and the short flower is increased. And the node of the flower can be improved.

If the first flower is opened in the seedbed 90 days after sowing, the 2 , 4-D stained flowers should be used in time , and the lower side branches should be removed. The method of preventing falling flowers and forming stone is mainly to ensure the light, supply nutrients, avoid the temperature rising and falling, and pay attention to the soil to keep moist.

As for the sowing time, it can be estimated to be 90 to 100 days according to the local greenhouse cultivation period . The varieties are generally made of local stable high-yield varieties, and can also be selected according to the variety of solar greenhouses.
