Eggplant is a Solanaceae vegetable, native to the tropical East India region, has a long history of cultivation in our country.
First, the cultivation of winter and spring quail eggplants in greenhouses is only a few years old and the experience is not very mature. From the practice in Anshan, Liaoning Province, it is known that seedlings will be planted in early September, planted in late October, and harvested before and after New Year's Day.
Second, nursery technology
1. The selection of fine varieties Now that China has not yet used the varieties for greenhouse use, it is only possible to select varieties with low degree of plant opening, early maturation and fast fruit development from the open field plant varieties. Such as Xi'an, green eggplant, seven-leaf green eggplant, purple long eggplant, according to the specific circumstances of each country to choose the right variety.
2. Cultivate strong seedlings for early maturing and high yield, eggplant seedlings need to grow 9-10 pieces of compound leaves, have buds can be planted. The nursery time is 90-100 days.
3. Seed treatment eggplant seed coat thicker, best hot water sterilization method. With hot water 50-55 °C for 10-15 minutes, remove and wash with cold water, and then soaked in warm water at about 25 °C for 24 hours. You can also use powder dressing or medicine soaking disinfection. The fully saturated seeds are wrapped in a wet towel and germinated at a temperature of 30-35°C. Every day, wash with clean water and wash off the substances that inhibit germination on the seed coat. Usually 4-5 days to germinate.
4. The seedbed soil shall be composed of 4 parts of Daejeon soil or scallions, 4 pieces of ash or mature manure, 1 piece of decomposed manure, and 1 part of fine sand. 1 cubic meter of bed soil plus superphosphate 0.5-1.0 kg, fully mix and sieve. Soil bed soil disinfection is also required. General sowing in mid-September. Before sowing, the bed soil is tiled with 10 cm, soaked in the bottom water, soaked after the water infiltration, 20 grams of 1 square meter seedbed. Need 30-35 grams of seed per acre seedlings bred, so need to seedbed 2-2.5 square meters. After sowing, cover soil 1 cm and then cover with a film, and make the seedbed temperature reach 20-25 °C.
5. After 70% of the seeds in the seedling management seedbed emerged, the plastic film covering the bed soil was removed. Always spray water to keep the soil moist. During this period, we must pay attention to the prevention and control of underground pests, the method is to use 80% of dichlorvos EC, plus 1200-1500 times diluted in water after pouring on the seedbed. When there are two true leaves in the seedlings, separate seedlings are to be prepared, and the seedlings for the seedlings shall be prepared, and the seedlings shall be transplanted at a spacing of 8 cm and 8 cm. After the relocation, it should be irrigated, and keep the high temperature to promote the slow seedlings. 28-30 °C during the day, about 20 °C at night, 2-3 days can be slow seedlings. When the seedlings grow to 9-10 true leaves, 7-10 days before planting, cutting and drying are started.
The seedlings are cultivated at low temperature by irrigating the seedbeds and then cutting the seedbed soil into pods to gradually increase the amount of air release. Remove grasshoppers at night and properly control temperature and moisture before planting. The standard of eggplant seedlings is: 50-60 days of seedling age, plant dwarfing, upright and straight, door buds budding, dark green leaves, complete roots. An insect pest control was also conducted before planting, and sprayed with 40% dimethoate 1200-1500 times or deltamethrin 5000 times.
