Field management eggplant field management

1. After planting live trees in the topdressing station, intertillage and scarification are combined to raise seedling fertilizer once, and one mu of decomposed human excrement and urine is about 1 1,000 kg. When the first fruit (Meneggplant) began to form, 65,438+0,000 ~ 65,438+0,250 kg of decomposed human excrement was applied as a fruit-promoting fertilizer per mu. After the first batch of fruits are harvested, heavy fertilizer should be applied once, with 2000 ~ 3000 kilograms of human excrement and urine per mu. Phosphorus and potassium fertilizer must be added to the organic fertilizer to meet the needs of rapid fruit expansion. In the future, according to the growth of plants, topdressing should be done every 7 ~ 15 days, which can flexibly grasp the types, fertilization periods and times of fertilizers. July, when eggplant is abundant, is the period when fertilizer is most needed. If the fertilizer is applied again, it will promote the survival of plants at high temperature, prolong the harvest period and increase the later yield.

2. Water management is best to ensure that the soil moisture reaches 80% to facilitate the growth of eggplant. In the early stage of eggplant growth, watering can generally be combined with topdressing. In order to prevent the flower from falling, the water should be controlled when the first bloom is planted, and the eggplant fruit should be watered in time when the sepals are exposed to promote the fruit growth. The water demand of eggplant increases during the fruit-bearing period, so it should be watered in time according to the growth of the fruit. In the hot and dry season from July to August, frequent irrigation is needed. Irrigation should be conducted in furrow irrigation in the morning or evening when the water temperature and ground temperature are low. Drainage should be done in time when it rains a lot. The drainage ditch should be opened in rainy season to prevent siltation. If water is found in the field, it should be removed quickly to prevent waterlogging and diseases.

Third, intertillage soil preparation and intertillage weeding are combined. Eggplant has low ground temperature and slow rooting in the early growth stage, so it should be cultivated frequently. Early intertillage should be shallow and late intertillage should be deep. When the height of the plant is about 33 cm, intertillage and soil cultivation can be combined with fertilization, and soil cultivation and root protection can be carried out at the base of the plant stem to prevent lodging. Eggplant has luxuriant branches and leaves in the late growth stage, which is easy to be blown down in strong wind and can be cultivated for many times to resist wind damage.

Fourth, pruning the eggplant with spreading leaves can't be pruned generally. Only a few side branches near the roots below the eggplant are removed to prevent the ineffective consumption of nutrients and facilitate ventilation and light transmission. If the leaves are threshed too much, the leaf area will be reduced, which is not conducive to the growth and development of fruits and will reduce the yield.

4 How to do a good job of site management

1, timely check and replenish seedlings: thin seedling fertilizer should be applied in time to avoid burning seedlings, and nitrogen and phosphorus fertilizers should be used together to promote early growth and rapid development. Check the seedlings frequently within 20 days after transplanting.

2. Water management:

(1) Before the whole ridge is covered with plastic film, the ridge soil must be kept in a semi-humid state.

(2) Pouring sufficient root-fixing water: it can be applied together with drugs and fertilizers. Transplanting in fine weather and watering the roots are especially important for K326.

(3) Returning seedlings to clumped trees: no serious drought will occur during this period, and no irrigation will be carried out. From the flourishing period to the mature period, the border soil should be kept in a semi-humid state, and after the border soil is completely wet, it will be drained in the ditch. During the drought, water should be replenished, and water should be poured in the ditch every harvest in the mature period.

(4) Drainage: There is more rain in the field growing season, so ditch cleaning and drainage should be done well to reduce fertilizer loss.

(5) Mulching and ridging: Mulching and ridging are carried out before tobacco plants enter the open period (about 20 days after planting) to prevent root damage. Cover the soil with plastic film immediately after ploughing, and press the film with clods. At the same time, weeds in tobacco beds and furrows should be shoveled manually to ensure that there are no weeds in tobacco fields. Or uncovering the film, cleaning ditches, weeding and ridging in the early stage of vigorous growth. It is required to completely remove the plastic film to protect the root system of tobacco plants and prevent the occurrence of root diseases in the vigorous period of tobacco leaves.
