Stepping into spring, it is time for farmers to start planting eggplant, so what do you need to pay attention to when planting eggplant in spring? Below, the editor of the Green Food Network will introduce to you.

Eggplant

Eggplant likes to be fat and avoid continuous cropping. The base fertilizer should be fully applied, and each mu of field can be applied with 6000-7000 kg of mature pile manure, 40 kg of phosphate fertilizer and 100 kg of plant ash, ploughing and ploughing. According to the row spacing of 55 cm south-north direction trench, ditch depth of 6 cm, eggplant plant distance of 38 cm 40 cm, first put eggplant seedlings covered with soil and then watered, and then ridged the next day. There are also large and small rows of 60 cm and small rows of 50 cm. After ridging, the small row spacing is covered with film, and 2600 eggplant seedlings can be planted per mu. The temperature is kept between 25 ℃ ~ 30 ℃ in daytime and 15 ℃ ~ 20 ℃ at night, and can be properly ventilated at noon. After April, the ventilation rate of the arch shed can be gradually increased according to the weather conditions, but the temperature must not be lower than 15 ℃ at night, otherwise the eggplant that is blooming and fruiting will fall. It can be released day and night until the temperature of the external environment exceeds 15 ℃ in mid-late May.

The film covered with eggplant should be cleaned frequently during the low temperature period, so that the eggplant seedlings can absorb as much light as possible. It is best to hang an aluminized film reflective curtain on the north side of the greenhouse, which is very effective in increasing light and temperature. Moisture should be properly controlled, except for watering slow seedlings on a sunny day within 3-4 days after planting eggplant, generally do not water, when the eggplant grows to the size of walnut, start dark irrigation under plastic film, when the soil temperature reaches 18 ℃ in mid-late March, you can water the eggplant every 5-6 days after warm weather to keep the soil moist. After starting watering, you can fertilize the eggplant every half a month, applying 20 kilograms of ammonium nitrate per mu each time.

In order to improve the ventilation and light transmission conditions of solar greenhouse cultivation, double-trunk pruning is feasible. After the formation of a pair of eggplant, two lateral branches are cut off and become double-trunk in two directions. After that, all the side branches on the eggplant should be knocked off. Generally, the plant is coring after the eggplant has seven eggplants.
