What techniques are needed to produce high quality eggplant in contemporary greenhouse eggplant cult

<>1.Seeding techniques

Before implementing eggplant planting in greenhouses, it should be ensured that the seedbed is adequately hydrated. When sowing, it is also necessary to water the seedbed thoroughly to further ensure that the moist soil layer is about 10 cm. For the prevention and control of cataplexy, wet powder and fine soil are used, mixed and stirred to cover the seedlings, which has a very good effect.

In order to keep the yield of eggplant cultivation at a stable level, the amount of sowing needs to be controlled to 10 grams of square meters. When the seeds reach the seedling stage, they must be covered with a shade net at the top of the greenhouse, and they can also be covered with straw, which can create a suitable environment for the growth of seedlings and effectively ensure the overall quality and actual yield of eggplant planting.

2.Pre-sowing preparations

1) Nutrient soil preparation.

Generally speaking, in the process of nutrient soil preparation, pastoral soil and humus soil should be fully mixed together, the proportion of the two is controlled at 6 4, and then diammonium phosphate is added, and the measurement needs to be controlled at 2 kilograms of cubic meters, and then mixed to make it. In order to prevent the occurrence of pests and diseases, it is necessary to sterilize the prepared nutrient soil at high temperature or add pesticides appropriately.

2) Seed treatment.

In the process of eggplant cultivation, pests and diseases are the main factors that threaten the yield and quality. In order to avoid pests and diseases, priority should be given to eggplant seeds before sowing. For the treatment of eggplant seeds, three treatment methods are often used, such as drugs, soaking seeds, and drying seeds, and the so-called sun-drying treatment is to expose the seeds to the sun for 1 2 days before soaking.

In order to ensure the germination ratio of eggplant seeds, after the soaking operation is completed, germination needs to be carried out, and the detailed operation is to put the eggplant seeds processed by soaking, put them in a sealed plastic bag, and the ambient temperature is controlled at 25 30, when the germination rate of the seeds is observed to be more than 60%, the implementation of sowing begins.

3.Seeding time

July and August is a better time for greenhouse eggplant sowing, and the specific time of sowing should be effectively determined according to the local market needs. At the same time, eggplants can also be grown in batches to ensure a sustainable market. Eggplants are generally planted in July and August, and the planting period is between October and November, and the best time to market is from December to the next year.

For vegetable farmers, being able to achieve a sustainable market is also a major factor in ensuring profitability. Therefore, vegetable farmers should implement cultivation work in batches according to the actual greenhouse situation.

4.Seeding management

In the process of selecting eggplant varieties, we should consider the winter climate conditions and sun exposure, and also choose an environment that is relatively suitable for eggplant growth. Therefore, when choosing eggplant seeds, it is necessary to choose those with strong cold resistance and low light demand. In addition, it is necessary to consider the yield and quality comprehensively, and it is necessary to choose eggplant varieties with high nutrient content, which are relatively easy to achieve high yields, and also choose varieties that are suitable and can prevent pests and diseases according to the planting environment.

First of all, when planting, we must choose the soil is more fertile and broad land, and we must use farmhouse fertilizer when fertilizing, do not use the fertilizer bought outside, and often water the plants, but also to prevent the occurrence of pests and diseases, if there are small insects, then we must spray insecticides in time. I think that if I can do these things well, I will definitely be able to produce high-quality eggplants.

It is necessary to strengthen urban and rural management, to choose suitable varieties for planting, to prepare high-quality fertilizers in advance, to ensure the fertility of the soil, but also to soak the tomato seeds and germinate in time.

It can be planted and cultivated through mechanical cultivation and breeding, and can be used to produce wide rental products through science and technology, control the planting temperature, planting humidity, and achieve the effect of artificial watering and fertilization, and pay attention to the density.

Planting high-quality eggplant requires 1. Cultivating strong seedlings, and scientific treatment of seedlings is needed during the seedling cultivation period, so as to improve the resistance and growth ability of seedlings. 2. If the greenhouse planting method is applied, the planters need to start deep soil ploughing in August and September, and at the same time strengthen the degree of sun exposure to the planting soil, so as to play a role in soil disinfection. 3. Furrowing.

After the planting soil has been treated, the planter needs to furrow.

When planting eggplant, we must be careful to choose the right season, to plant reasonably densely, but also to ensure that the soil is moist, the soil is fertile, in the process of planting to the hail skin to be properly watered, fertilized, but also to ensure that the sun is sufficient, the temperature is kept within 25.

When planting eggplant, you must choose the right place to plant it, and you can choose a place with high ground for cultivation. Trenches should be dug to prevent water accumulation in the land. It is also necessary to choose suitable varieties in the selection of liquid hidden varieties, varieties with strong resistance to weak light and resistance to round disease.

It is necessary to protect the root system of the eggplant so that the eggplant can grow better.

Choose high-quality varieties as much as possible, and turn the soil in advance, choose loose and fertile soil, and sow seeds in a timely manner.

Eggplant has wide adaptability, long growth and fruiting period, high and stable yield, and is resistant to storage and transportation, and is deeply loved by people. The cultivation of eggplant has certain requirements for soil, temperature, light, moisture and nutrients, specifically. Soil.

Eggplant prefers sandy soil with a lot of organic matter, loose soil, good drainage, and strong water retention. Temperature. The suitable temperature of eggplant growth and development period is 20-30, and the suitable temperature of fruiting period is 25-30, lower than 17 or higher than 35, which will cause flowers and fruits or deformed fruits, below 10 stop growing, and -2 -1 will freeze to death.

<> light. Eggplant has higher requirements for light intensity, under low light, photosynthesis decreases, yield decreases, purple varieties have bad color, large color difference, affecting commodities, insufficient light at seedling stage, flower bud differentiation and flowering delay, long teasing column flowers decrease, short column flowers increase. Fertilization, land preparation and rotten.

Before planting eggplants, do a good job of plowing the ground. The site is ditched from south to north, with a small row spacing of 70 cm, a ridge height of 15 cm, and a large row spacing of 90 cm, making a large and small row of high ridges from north to south, with a plant spacing of 40 cm, that is, a large row of double rows of high ridges for cultivation and planting, with 2200-2500 plants per hectare. Chemical fumigation of the greenhouse is carried out before planting, and the greenhouse is fumigated with sulfur, dichlorvos and sawdust mixed after the greenhouse is disinfected, and the ventilation is carried out after 24 hours before planting, and the closed greenhouse film is fumigated for 48 hours, and the amount of sulfur and dichlorvos is used per 100 square meters, sawdust.

The selection of excellent varieties is the direct cause of the yield and quality of eggplant, so it is necessary to choose the right variety according to different regions and environments. In the northern region, it is mainly green tolerant, disease resistant, heat-resistant, rain-resistant, purple-skinned, white-fleshed round or long rod-shaped, such as Hongfeng, Nongyou and other long eggplant varieties; In the south, it is mainly varieties with strong resistance to Fusarium wilt and Verticillium wilt, such as Guilin eggplant and other varieties.

Do a detailed interpretation of the problem, I hope it will help you, if there are any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

1. Protect the root system. In the process of eggplant cultivation, from the beginning of seedling raising to the end of production, attention should be paid to protecting and promoting the development of the root system in every link. 2. Seedling division and root protection and seedling raising.

The number of defeats and seedlings can not be too much, and it is necessary to divide the seedlings into a nutrient bowl or bag to protect the roots and raise the seedlings. 3. Deep turning and fattening. Deep ploughing and a large amount of organic fertilizer is the basis for promoting the development of eggplant roots.

It is necessary to choose a better variety, and the first planting spacing should be wide, second, the seed script should be buried in a place where the sun is more sufficient, the first is to know the third, to water in time, fourth, to fertilize in time, and fifth, to remove the weeds in the field in time.

It is necessary to use scientific methods to grow high-yield and high-quality eggplant, first of all, through selection, select good varieties of seeds, leak Hanwang and then return to the juvenile to use grafting, find vigorous plants for cultivation, so that the quality of eggplant old lines will become better.

It is necessary to adopt a superstitious asana pattern to grow a high-yielding eggplant, and the first and first to go through the selection, select the seeds of the variety, and then which shed to touch the grafting, and find the vigorous plant to carry out the cultivation, so that the virtue of the eggplant becomes.

First, choose good breeds.

The selection of eggplant species is mainly green and disease resistant, high temperature and rain resistance, purple-red skin color, milky white fruit, and long stick shape. The varieties with fruit length within 30 cm are Hongfeng, Changfeng, Zaofeng, Nongyou Long Eggplant, Guilin Long Eggplant, and Yue Tomato No. 2, Yuefeng, Shijie Red Eggplant within 25 cm long. Among them, the Hongfeng fruit grows, is uniform, and has a beautiful appearance.

Yuezhi No. 2 is highly resistant to bacterial wilt and verticillium wilt; Yuefeng, Shijie red eggplant has a deep tone and a very good gloss; Guilin eggplant has a high yield and is resistant to disease, but the fruit is green.

Second, select the land and prepare the land.

The seedbed and planting land should be selected as a plot of non-solanaceae crops, preferably a paddy field, deep ploughing and exposure, and a high furrow above 30 cm. furrow wide package ditch, double row planting rice, single row planting 1 meter. The seedbed should be sprayed with pentachloronitrobenzene or dixone 500 times double insecticidal double 800 times solution 7-10 days before sowing, and covered with plastic film for disinfection and sterilization.

Third, cultivate strong seedlings.

Before sowing, the seeds should be sterilized and dormant should be broken. The disinfection method is: soak the seeds in 10% trisodium phosphate or potassium permanganate solution for 20 minutes, and wash them with tap water for about 30 minutes after removal, so that the surface of the seeds is clean and free of mucilage; Or soak the seeds in 55 minutes of warm boiled water.

The treatment method to break dormancy is: add 2kg of water to prepare an aqueous solution with 1 gram of auxin (ninety-two), soak the seeds in the aqueous solution for 4-5 hours, wash with tap water for 10 minutes, drain, and then sow seeds.

Fourth, reasonable dense planting.

The row spacing of double row planting is 50-60 cm, the plant spacing is 50 cm, and 1000-1200 plants are planted in 1 mu. The spacing of a single row of plants is 40 cm, and 800 plants are planted in 1 acre. After planting, it is necessary to drench enough water to fix the roots, and after a week of slow seedlings, you can start to apply a small amount of water and fertilizer, and at the same time, you should pay attention to check the harm of tigers and the occurrence of blight, and replenish seedlings in time.

Fifth, pruning in a timely manner.

When the main stem appears when the flower bones appear, start to cultivate the soil, after the soil is moderately planted with bamboo and tie the vine, the whole branch, the first flower on the petiole (root eggplant flower) should be cut off, except for the first branch below the root eggplant, the other branches under the petiole are all cut off. In the large-fruited species, in addition to leaving one branch under each inflorescence, the other branches can also be cut off. For overgrown or overgrown stems that are planted too densely, a portion of the leaves should be cut off to ensure that the fruit grows normally and is fresh in color.

Eggplant likes temperature and heat tolerance, but is afraid of dry heat and cold, the suitable temperature for growth is 15-30 degrees, and it should be maintained at 25-30 degrees for a long time in a day, and maintain a constant temperature difference between day and night (not lower than 15 degrees at night). Therefore, according to the local temperature and light and other climatic conditions, the fertilizer effect of organic fertilizer is long, the stamina is sufficient, and it is not easy to defertilize, and at the same time, organic fertilizer fertilization is deeper, and it is not easy to cause fertilizer damage. Organic fertilizer should be selected chicken manure, pig manure, etc., and the amount of pure chicken manure per mu of greenhouse should not be less than 6 000 kg, or pig manure should not be less than 8 000 kg.

Cultivation method: The suitable growing temperature is between 10 and 25 degrees Celsius, but it will grow best between 16 and 23 degrees Celsius. For farming, we generally choose the soil quality that is fertile, loose, breathable and well-drained.

Selection of seedlings, eggplant in winter and spring greenhouse planting, should be selected cold resistance strong yield, and market prospects of excellent varieties, before sowing, should be selected dry terrain, ventilation, convenient drainage, so that there is no problem.

Because of the low ground temperature in early spring, various irresistible climatic factors can erode the natural growth of eggplant at any time. Only eggplant varieties that are resistant to low panicle temperature and weak light can maintain a strong fruit-setting ability in a specific production hidden climate, so that the eggplant fruit can be covered with a three-layer membrane in a harsh growth environment, and a small public shed can be used to raise seedlings in a nutrient pot. Transplanted to the greenhouse, the greenhouse should be covered with three layers of film, and the flowers should be dotted to make the eggplant grow straighter.

If there are many leaves, prune the leaves. It is planted at the end of November and harvested in February. It was planted in March, and the stove pickers harvested it in April.

The temperature is kept at 25-30 degrees.

After years of cultivation and planting, eggplant has produced many varieties, and we should adapt measures to local conditions when choosing, for example, the average annual temperature in some areas is high, and varieties with good heat tolerance should be selected when planting; On the contrary, if the average annual temperature is low, it is necessary to choose cold-tolerant varieties; In some areas, there is more rain, the plant height is about 15 cm, 5 7 true leaves, the leaf color is dark green, the root system is developed and complete, and there are no diseases and pests. In addition, eggplant is a fertilizer-loving crop, in order to achieve high yield of eggplant, it is necessary to apply foot fertilizer, and the soil should be finely broken and loose to ensure good air permeability and water and fertilizer retention capacity.
