Eggplants want high-yield planting, and they can choose to cover and cultivate the mulch. It can increase the yield by more than 30% than the average open field cultivation, and the early yield can be multiplied.
1. Variety selection:
In the selection of varieties, the growth requirements of eggplant should be met. Suitable for mulching eggplant varieties, should choose cold-resistant, high-yield early-maturing varieties or very early-maturing varieties, such as Tianjin fast round eggplant, Xinxiang rough green eggplant, Jinan early small long eggplant, purple odd=Tianjin five-leaf eggplant, Beijing six-leaf eggplant and many more.
2. Nursery time:
Seedlings are grown in hotbeds or in greenhouses at the end of January and early February.
3. Film cover method:
The common methods of mulching cultivation in China's growers include mulch mulching and mulching cultivation, mulching and mulching cultivation, mulch mulching and small arch shed cultivation, and high ridge furrow mulching. The sorghum ditch is covered by mulch film. The general standard is that the glutinous surface is about 80 cm wide, the sorghum is about 20 to 25 cm high, the row spacing is about 50 cm, the planting groove is 15 to 20 cm wide, and the bottom width is ten. Two to fifteen centimeters; mulch mulch cover cultivation, the general standard is that the width of the glutinous rice is about sixty centimeters wide, and the width of the sorghum is eighty to ninety centimeters; the sorghum mulch is covered with small arch sheds, and the general standard is sorghum back width sixty. The size of the centimeter is about ten to twenty centimeters high, the small arch shed is 40 centimeters high and 70 centimeters wide; the standard for high ridge furrow mulching is 60 to 65 centimeters, and the ridge is 20 to 25 Centimeter, the planting ditch is 20 cm deep, the mouth is 15 to 20 cm wide, and the bottom is 15 cm wide.
4. Site selection and land preparation:
When selecting a plot, choose a plot with fertile soil, loose soil, and high ground. When determining the planting plot, the tillage should be deep tilled immediately after harvesting. Too much water in the soil requires repeated tillage and fine evaporation, so that the soil is wet and not wet. Before the rainy season, the whole land will be smashed, with an average line spacing of 40 to 45 centimeters for ridges or small stilts. When ridges, it is best to prepare large and small shapes. The sorghum is 15 centimeters high, 60 centimeters wide, and 20 to 30 centimeters wide. These should be completed from about one week to ten days before planting, and covered with plastic film to prevent excessive soil moisture. , causing seedlings to not cause or even cause disease, resulting in lack of seedlings or seedlings weakening. In the later stage of topdressing, it is not convenient to apply fertilizer after mulching. In the case of soil preparation, it is necessary to apply base fertilizer at one time, especially topdressing fertilizer. As far as possible, soil fertilizer can meet the growth needs of eggplant for a long time.
5. Strong seedling colonization:
The time of colonization is generally carried out during the frost-free period, that is, after the end of the night, the cream should be carried in time. If it is too early, it is vulnerable to the damage of the night cream. In the specific planting, the pits are opened in two rows according to the distance of 20 cm. After the nursery is cultivated, the water is poured in the pit. After all the planting is completed, the water is poured into the ditch, and the purpose is to stabilize the seedlings.
6. Field management:
After the stalks have been made, each plant retains only the stalks and three eggplant stalks, and the leaves and side branches below the stalks are all removed. After the fruit of the "four-door bucket" is fruited, the branches of each fruit are smeared, and all new side branches are removed. The "four-door bucket" fruit was harvested and pulled. This plant adjustment method is suitable for early spring cultivation of eggplant covered with mulch. At the time of colonization, the density is larger. When the plant is seen, the topping of the eggplant is topped, and the eggplant is removed after harvesting, so that the plant density is halved to ensure normal growth in the middle and late stages. This pruning method improves the early production while taking into account the total production.
When the eggplant is about 150 grams, it can be harvested and listed. When the eggplant grows to 250 grams, it can be harvested.
The above are some of the key points of eggplant high-yield mulch technology. I hope that some help for eggplant growers, more knowledge about eggplant cultivation, please pay attention to the Hui Nong School!
