First, field finishing
Eggplant is not tolerant. After the summer of eggplant planting, it will enter the high temperature rainy season. The sandy loam soil with high topography should be selected. The clay loam is poor in permeability, and in the case of rainy years, easy to die, you should dig a good irrigation and drainage ditch, leveling the land to prevent accumulation of water and rain. In addition, it is advisable to use a small box. The box height is 20-45 cm, the width of the box is 100-120 cm, and the width of the box is 20-30 cm.
Eggplant is a deep-rooted, hi-fertilizer, fat-tolerant vegetable. It is advisable to deepen the basal fertilizer. Mushi rotted 5,000 kg of organic fertilizer, 40 kg of monoammonium phosphate, 30 kg of potassium sulfate, spread evenly, and deep level; if the fat source is sufficient, more than 10,000 kg of organic fertilizer can be applied per acre and evenly spread. Calcium phosphate 50 kg; if the organic matter in the soil is sufficient, chemical fertilizers can all be used. Mushi granules urea 100 kg, superphosphate 50 kg, potassium sulfate 50 kg.
Second, planting eggplant colonization period is generally after the harvest in early June to early July. However, it should not be too late as early as possible to facilitate a period of time before the midsummer.
Colonization should be observed at noon within 1-2 days of colonization. The seedling period should be 30°C during the day and 18-20°C at night. 28-30°C during daytime and 15-18°C at night. The summer eggplant grows for a long period of time. It does not prune in the previous period and leaves it to grow. After the harvest, the old leaves will be removed. After the eggplant is formed, the upper two outer branches will be cut to form a double stem. Branches, and so on. When the four-door bucket egg sits up and picks up the heart. Usually leave 5-7 eggplants per plant. In the middle and later stages, the degree of plant development is large, and the planting density is preferably 1800-2000 plants per mu. Planting should be deeper. Pour plenty of water after planting to ease the seedlings. When the door tomato emerges, strengthen the cultivator to prevent grasshoppers. In the rainy season in summer, fertilizer and water should be strengthened. After 7 days of planting, the water should be poured once and the water should be controlled until the water is used to control watering and fertilizer. When the door grows to 3-4 centimeters in size, it starts to top-dressing and watering, under the film, under irrigation.
Eggplant hi water, pay attention to keep enough of the soil moisture. Water and furrow irrigation can be performed when water is scarce. When watering, the fertilizers such as ammonia, monoammonium phosphate, and potassium sulfate were dissolved in water at concentrations of about 0.3%, about 0.15%, and about 0.2%, respectively. When furrowing, fill a ditch with large water and then evenly spread the above fertilizer in the ditch. The amount per mu can be 15-30 kg, 10 kg and 10 kg respectively. If there is no shortage of water, you can dig a nest in the middle of every four eggplants and put enough ripe manure in the nest. Note that after top dressing, ventilation should be increased to prevent the occurrence of fertilizers and diseases. After topdressing for the first time, chase 1 time every 15 days. Each time mu recovers 10-15 kg of urea, 10 kg of diammonium phosphate, 5 kg of potassium sulfate, timely watering, promote the growth and development of plants and fruits, prevent premature aging, and prolong Harvest period, increase late production and economic benefits.
The flowering stage can be used to apply flowering stalks and calyxes with 20-30 mg/kg rhibarb. The treated corollas should be removed after the fruit is large to increase the fruit setting rate.
In summer and autumn, we should pay close attention to the work of weeding, weeding and pest control. Weeding can use 48% trifluralin 100-150 grams per mu and spray the ground after planting. Both can achieve a good insecticidal effect, but also reduce the use of labor.
