Is there any technology for eggplant cultivation? How should eggplants be grown?

Eggplant planting and seedling breeding varieties are selected with low temperature resistance, light resistance, fruit type, disease resistance, high quality, high yield, convenient storage and transportation, good commerciality, and suitable for market demand. Depending on the seedling season, you can choose nursery facilities such as greenhouses, solar beds, and hotbeds. Summer and autumn seedlings should be equipped with insect-proof and sun-shading facilities to create suitable environmental conditions for the growth and development of eggplant seedlings.

Eggplant seed coat is thick and has a long soaking time. The seeds are first sown with cold water for 2 3 minutes, then soaked in 50 warm water for 15 min, then washed with clean water, then soaked in warm indoor water for a day and night, then washed with clean water, then wrapped in a damp cloth, and then placed in 28 conditions for germination. Rinse with water every 4 hours and germinate after 4 days.

Wash with warm water every 6 hours for 28 each time, germination after 3 days. More than 80% of the seeds can be sown when they break their mouths. Summer and autumn birth control seedlings can be sown directly with sterilized seeds.

Fertilization management. If there is enough organic fertilizer in the subsoil, the seedlings will grow normally and do not need top dressing. At the seedling stage, if the seedlings are found to be light green and thin, the fast-acting fertilizer can be properly covered with water.

That is, the water-soluble amino acid foliar fertilizer and urea are dissolved in a ratio of 1:1 with warm water, and then the solution is sprayed in a spray can. Then spray again with clean water to prevent the leaves from burning.

In order to cultivate seedlings, the temperature and humidity should be reduced one week before planting. In early spring, the temperature of seedlings is controlled at 20 during the day and 10 at night. In summer and autumn, the seedlings gradually remove the shade net and properly control the moisture.

Of course, the prevention and control of pests and diseases is also indispensable, and this situation can be controlled by irrigation of dry crops and silver ions.

7 to 10 days before planting, the eggplant seedlings were refined at low temperature to adapt to the environment of low temperature and large temperature difference between day and night in the greenhouse in early spring. When the shed temperature is not lower than 10, and the ground temperature of 10 cm is stable above 12, choose a sunny day to plant in the morning. After planting, it is best to carry out multi-layer mulching such as small arches.

After the door eggplant is harvested, the outside temperature rises, and the ventilation time should be appropriately advanced, and the vent should be from small to large. When the outside night temperature reaches more than 15, ventilate day and night, and when the outside temperature is stable above 22, you can gradually remove the greenhouse film or leave only the top film, and cover the greenhouse film with a shade net. It is necessary to remove the old leaves and axillary buds below the root eggplant in time.

After the four door buckets, some areas in the "eight-sided wind" after the big buds, leave 2 3 leaves in the upper part of the flower buds to pluck the top, which is conducive to early maturity, high yield and upper fruit expansion, and timely removal of axillary buds, in the middle and late stages of picking off the lower disease, old, yellow leaves, in order to facilitate ventilation and light, reduce nutrient consumption, and promote fruit growth and development. Eggplant planting in spring greenhouse is early, the temperature is often below 15, and the lack of light is easy to cause flower drop and bud fall and form deformed fruits. At the time of flowering, the roots can be irrigated with silver ions of dry agricultural products, which can prevent flower fall and promote fruit expansion.

Eggplant is a very common food in the market, and many netizens like to eat eggplant very much. In fact, eggplant looks very common, but it is still very troublesome to grow. First of all, when planting eggplant, you need to choose the whole field, and then you can start planting after fertilizing the whole field.

Before planting, the eggplant seeds need to be soaked and germinated, and when the germination is successful, the seedlings can be sown. Wait until the eggplant seedlings grow slowly and steadily before planting the seedlings into the soil, and you must pay attention to choosing warm weather for planting, otherwise it will also affect the growth of eggplant seedlings. <>

Pay attention to watering after planting the seedlings, this time the watering is the effect of fixing the roots. It will come to an end after watering, but we must pay attention to post-management, pay attention to weeding during the growth of seedlings, and fertilize eggplant seedlings regularly and quantitatively. When planting eggplant, you must choose a place with loose soil, because the roots of eggplant breathe very actively, if you choose very clay soil when planting, it will cause the eggplant to be unable to breathe.

Fertile soil and planting eggplant also requires very fertile soil, so most of the soil needs to be fertilized before planting, and only when the fertility in the soil is increased, can eggplant grow normally. In the early days, we start planting eggplants in December, and if we want to plant them in late autumn, we can choose to plant them in May. Whether you choose to raise the seedlings in December or May, you need to germinate the eggplant seeds, so that the eggplant seedlings can grow as soon as possible.

After planting the eggplant into the soil by regular pruning, it is also necessary to weed regularly, and do not leave it alone, otherwise the presence of grass will also affect the growth of the eggplant. After planting, the eggplant should be fertilized every half a month to meet the nutrients needed by the eggplant in the process of growth. If the eggplant becomes very dense during the growth period, it is not a good thing for the eggplant to grow by properly pruning the branches and pruning the eggplant too densely.

The whole process of eggplant planting is germination, seedling raising, land preparation, transplanting, watering and fattening.

1. Germination. Eggplant is a Solanaceae plant that is suitable for sowing between January and February in the spring. Before sowing, the seeds are soaked in warm water at about 50 degrees for more than 2 hours, and then soaked in gibberellin solution for 20 24 hours for germination.

2. Seedlings. Once the eggplant seeds have budded, they can be sown in loose, airy and well-drained potting soil. After sowing, the first watering should be sufficient, the water needs to be controlled in the later stage, the temperature is stable at about 20 degrees, the seedlings can emerge in about 10 days, and thin fertilizer can be applied appropriately after the seedlings emerge.

3. Land preparation. After the eggplant seedlings have grown steadily, they can be transplanted in the soil with a deep layer, soft soil, breathable and well-drained soil. The land should be weeded in advance, loosened and an appropriate amount of basal fertilizer should be applied to promote the growth of young eggplant plants.

4. Transplanting. When removing the eggplant from the pot, try to retain the soil ball at the root, which can avoid damage to the root system and help the root system adapt to the new soil. Dig a hole in the soil, move the young eggplant plants into the hole, cover the soil and compact.

5. Watering. After moving the young eggplant into the land and planting it, proper watering is required to soak the soil at the root of the eggplant, which is conducive to the eggplant taking root in the soil. In the later stage, it is necessary to control water, do not need to fertilize the eggplant, and avoid sun exposure.

6. Fattening. After 3 to 6 days, the root system of eggplant can adapt to the new soil, which can give the eggplant sufficient light, water and fertilizer, which is conducive to the growth of eggplant. In the early stage of growth, the fertilizer is mainly nitrogen fertilizer, which can promote the growth of branches and leaves, and can make them more green.

Eggplant should be planted in a warm and moist place, and the eggplant should be watered every day, and the water must be watered thoroughly, and there is a fertilizer every two days, which can make the eggplant grow healthier and more nutritious, and observe the changes of the eggplant every day, if there are bacteria or pests and diseases, it must be sprayed with pesticides in time.

First of all, we must choose fertile, soft, good air permeability, and good drainage soil, but also choose high-yield, resistant to diseases and pests to seeds, and also apply sufficient fertilizer, in the later stage to add more organic fertilizer, or farm fertilizer, but also to water more, so that the land remains moist.

Choose some high-quality root seedlings, then dig a pit, plant eggplant seedlings in, and then cover the soil with more watering, apply more fertilizer, and open the distance between the eggplant and the seedlings, and you're good to go.

Fertilize the whole plot first, then sow seedlings, choose the right planting method, and finally pay attention to management, but also water and fertilize regularly.

Eggplant has a strong growth momentum, many side branches, and leaves grow quickly, especially when the temperature is right and fertilizer is sufficient, the plant is more luxuriant. However, if the plant grows too densely, it will cause flower drop, rotten fruit, and poor fruit color. Therefore, trimming the leaves of eggplant can increase the yield.

Leaves are the organs that make and accumulate nutrients, and in general, the more leaves there are, the more nutrients are produced and accumulated. However, if there are too many leaves, it will affect ventilation and light transmission, and the old leaves and diseased leaves not only have a weak ability to produce nutrients, but also cause harmful diseases, so repair a part of the healthy leaves, remove the old leaves, diseased leaves, is conducive to plant growth and fruiting, spraying a new high-lipid film, can automatically form a layer of invisible polymer protective film, optimize the quality of plant water absorption, ventilation and light transmission. Shielding the signal of pest and disease and weakening the transmission vector, resisting and defending against natural environmental disasters.

Leaf pruning should remove weak branches and side branches at the base, as well as old leaves and diseased leaves, and appropriately remove overly dense healthy leaves to keep the leaves sparse and even, so as to facilitate ventilation and light transmission. During the whole growth period of eggplant, prune the leaves 4-5 times to prevent too many leaves from being pruned at one time and only a few leaflets on the top. About 15 days after the eggplant seedlings were planted, shallow tillage and weeding were carried out, combined with small soil and thin application of seedling fertilizer once, and 10-20 quintals of thin human manure per mu.

After the root eggplant sets fruit, remove the side branches below the root eggplant to avoid too many branches and leaves and consume nutrients.

During this period, the plants have not been sealed, and deep cultivation and weeding, soil cultivation, a top dressing is applied, and 50 kg of potassium sulfate compound fertilizer is applied per mu. When the plant grows into the middle and late stages, fertilizer should be applied once for each 2 harvests, and 15-20 kg of compound fertilizer should be applied per mu. At the same time, foliar fertilizers such as ribery, Yanwo powder, potassium dihydrogen phosphate can be sprayed.

Eggplant does not require much water in the early growth stage, and appropriate drought is conducive to flower bud differentiation and fruit setting rate. After the root eggplant sits on the fruit, the water required for plant growth gradually increases, and the soil should be kept moist and properly drained and irrigated.

1. Eggplant is generally planted by the method of raising seedlings first and transplanting later. However, there are not many plantations in the family garden, and it is very troublesome to raise seedlings by yourself, so it is recommended to go directly to the seed market to sell the seedlings and transplant them. There are many varieties of eggplant seedlings in the market, and you can choose the variety you need to buy.

When buying, choose a large plant with a thick stem, and prefer to be more expensive than to buy poor quality seedlings cheaply, so that the transplanted eggplant seedlings are easy to survive.

2. Eggplant is afraid of frost, is a warm plant, relatively resistant to high temperature, in the case of relying on the sky to grow, can only be planted in the local frost-free season. Generally, the seedlings are covered with film in early March, and the transplanting of seedlings begins in early April. However, due to the difference in climate between the north and the south, the planting time varies slightly from place to place, and this depends on the local climate.

Generally, the temperature at the time of transplanting is about 15-20 degrees.

3. If you want to have a high yield of eggplant, the land must not have grown eggplant for 3 years, and you must choose a semi-sandy loam soil with high terrain, no shelter, deep and fertile soil, and permeable up and down to plant eggplant. Because the growth period of eggplant is in the hot and rainy summer, if the land does not rotate, it will be diseased; And it likes light, if the soil is shady, does not drain, the air above and below does not flow, and the cultivated layer is shallow, it is not suitable for its healthy growth.

4. Dig deep and dig the cultivated land to ensure that the depth is the depth of the full hoe. And remove all the weeds and previous stubble residues on the land, and then build a good ditch. According to the proportion of 3,000 kg of high-temperature rotted farmhouse fertilizer per mu, apply it to the dug land, and then mix the soil and farmhouse fertilizer to make the soil and fertilizer even, and rake it flat to be moved.

5. Before transplanting, if you are afraid of the trouble of pulling the grass behind, you can cover a layer of black mulch film to prevent more weeds in the back and no one will pull the grass by hand. However, if you don't plant much in your own vegetable garden, it is recommended not to cover the mulch film, so as not to waste money. When transplanting, the principle of sparse planting should be used.

Generally, ridge cultivation is adopted, and large and small rows are planted. According to the large row spacing of 80 cm, the small row spacing is 60 cm, and the plant spacing is about 48 cm, and each hole is planted with a seedling.

6. After the seedlings survive, the soil should be kept dry and wet, and top dressing for the first time, mainly urea. Fertilization is applied according to the ratio of 15 kg of urea fertilizer per mu to promote the development of rhizomes and rapid seedling growth.

7. Every second top dressing is applied a few days before the eggplant flowering, fertilizing according to the ratio of 15 kg of compound fertilizer per mu, and using a hoe to cultivate the soil and hoe the grass after fertilization.

8. When the eggplant passes through the secondary branching, the first flower or the branches below the inflorescence should be erased, and some old leaves, residual leaves and yellow leaves at the bottom should also be removed, so as to increase the light transmittance between the branches and reduce the occurrence of some parasitic pests.

Branch pruning: The best time to prune is after the leaves have fallen, and the branches that are dry, have too many forks, and have fewer nodes are cut. Watering Management:

It is best to keep the moisture content of the soil at around 35%.

Persimmon tree planting method:

In fact, the method of planting persimmon trees is very simple. It is resistant to both drought and moisture. Home farming is effortless. However, if it is grown in a sunny and warm environment, it will be better health.

Branch pruning: The best time for pruning is after the main leaves have fallen, and the ones that are dry, have too many forks, and have fewer nodes can be cut off appropriately. In its environment, prune it to fit the type of tree.

Watering management: It is best to keep the moisture content of the soil where the persimmon tree is planted at about 35%, so that the persimmon tree can achieve the best growth state.

Fertilizer management: persimmon trees are mainly nitrogen fertilizer, followed by potassium fertilizer and phosphate fertilizer.

Clearing the garden: Winter cleaning is to prepare for the next year's flowering and fruiting. Cut off unhealthy branches and treat the infested areas appropriately. Thoroughly remove pests, dead branches, and diseased leaves from the source. There are many pests that rely on trees for the winter, so pay attention to cleaning up.
