As long as you master the core skills of vegetable planting, you can grow it well, what are the core

The core skill is that the soil used for vegetable planting must be relatively fertile and has good air permeability of various nutrients.

We must choose seeds with good quality, disease resistance and lodging, high yield and stable yield, consistent size, full particles, high germination rate and bright color, and at the same time ensure that the soil is moist, full of seedlings, strong seedlings, and reasonable watering and fertilization.

The core technology of vegetable planting is to control soil-borne diseases first, strengthen the roots first, prevent insect pests early, do not relax for a moment, and learn to make homemade organic fertilizer.

Farmer Lao Yang is a vegetable grower. He has been growing vegetables for two or three years, mainly leafy vegetables. Lao Yang said:

There is no confidence in growing vegetables this year. I always hear on the Internet that La Niña is coming this year, this year is a cold winter, this year is extreme weather, etc. This kind of news always feels that the vegetables planted this year will be frozen.

A few years ago, some overwintering celery and spinach were planted in the open field, but this year they are not planted. ”

I said, "Which one are you?" These dishes are hardy and should be kept warm a little.

For example, transplanting celery, watering enough water after seedlings, covering a layer of film before heavy rain and snow, and opening it again next year when the temperature is high, is very simple. "I planted some leafy vegetables like coriander and lettuce in the cold shed. The first two years were warm winter weather, not particularly cold, and I felt like I didn't have much management.

Only the quilt grows well. Lao Yang said. Frost damage has a great impact on vegetables, which grow slowly, or even stop growing, and the leaves wilt.

The leaves freeze as if they have been scalded by hot water, affecting yield and quality. Daily management should have sufficient fertilizer and water, and thermal insulation measures should be taken in time when the temperature in the shed is particularly low. There are two methods that are commonly used.

1.Promotes the growth of leafy vegetables.

Be aware of weather changes. Three or four days before the low temperature comes, you can spray antifreeze once to reduce the occurrence of frost damage. Antifreeze can be made from potassium dihydrogen phosphate and brassin, and some amino acid foliar fertilizers can be used for weak-growing vegetables and can also enhance the growth and resistance of vegetables.

2.Increase the temperature in the shed.

Coriander and spinach grow fast when the temperature is low, but for some lettuce and baby greens, too low a temperature can cause frost damage. If there is no frost damage, the temperature in the shed needs to be increased appropriately. Cover the quilt and two sheets of film to raise the temperature in the shed.

In addition, the use of insulation blocks in the shed is also a good way to keep warm. At night, a greenhouse can be heated up by about five degrees by about five degrees.

Both methods are good for preventing frost damage. Spraying antifreeze can promote the growth of plants and improve their resistance. In order to reduce the occurrence of diseases, fungicides can also be added, which is simple and labor-saving.

This method is used a lot. But when the temperature is extremely low, you have to find a way to raise it. If you have a heating block at home, you can use it.

It is also important to prevent frost damage during winter vegetable management. Although the temperature has not dropped significantly after winter, for vegetable farmers, it is necessary to master the tricks of anti-freezing in advance, so as to prevent frost damage from not knowing what to do and affecting the yield.

Planting vegetables in winter requires controlling the temperature and light suitable for vegetable growth, fertilizing and weeding frequently. Usually, it is necessary to ventilate and cover the vegetable greenhouse according to the weather, and pay attention to the humidity and moisture in the greenhouse. In addition, it is necessary to choose suitable pesticides to remove insects and resist diseases of vegetables, so that healthy vegetables can be grown.

First of all, we should pay attention to fertilization, in winter, you can apply some farmhouse organic fertilizer, sprinkle a layer of chaff ash or plant ash on the vegetables before the outside temperature is too low, and appropriately reduce the amount of nitrogen fertilizer, so as not to have poor cold resistance of the plant.

Theoretically, the longer the light hours, the more efficient the photosynthesis, the more organic matter the crop produces, and the higher the yield and quality.

In the north of our country, in winter, the light time is short, so we should try to extend the light time in the greenhouse.

As soon as the sun comes out, quickly uncover the quilt or straw, and cover it again after the sun sets. Of course, taking into account the temperature, it is possible to flexibly control the time.

The planting time should be the autumn season, and then fertilizer should be applied before planting, and after a period of time after planting, top dressing should be carried out, and attention should be paid to watering and fertilization.

Planting time Planting Chinese cabbage, generally from July to August, choose good seeds According to the local situation, choose the right variety of cabbage, the seeds are best fresh, shiny and full, so that the germination rate is relatively high. From July to August, it is generally rainy in various places, and we can sprinkle rotten cake fertilizer and farmhouse fertilizer in time according to the moisture.

It is generally better to plant in July. Seeds should be selected in advance, and then germination treatment should be carried out appropriately, and rotten cake fertilizer should be used for land preparation in advance.

The soil is loose, and the soil with good air permeability is called "sponge field", and the crop yield is the highest. Data show that the organic matter content of soil in most parts of China is about 1%, which is below the 2% limit suitable for vegetable growth. Therefore, the increase of organic fertilizer and straw returning to the field to improve the soil, avoid flood irrigation, the conditional areas are best to use micro irrigation or drip irrigation, so that the water slowly infiltrates into the soil, so that the tamping effect on the soil is small, is conducive to improving the air permeability of the soil.

At the same time, after watering, it is necessary to pay attention to timely cultivation and hoeing to assist in increasing the air permeability of the soil.

<>Of course, it can also be used if it is not rotten, that is, it is far away from the roots and rhizomes of vegetables, especially sheep manure water, which is very stinging, easy to burn the roots to death, and it is best to ferment them in a closed container. Special medicinal fertilizer refers to the combination of special fertilizer as a carrier, such as polyglutamic acid, small molecule polypeptide, fulvic acid and organic matter, and chemicals with systemic conduction.

Beneficial flora imbalance, according to the analysis of the theory of soil nutrient return, if you want to change the permeability of the soil, you must first increase the organic matter content of the soil, you can add rotten farmhouse manure or commercial organic fertilizer to the soil, increase the appropriate amount of microbial agents, promote the decay of organic matter, improve the buffering capacity of the soil to pH, increase the pH value of the soil, and the decomposition and utilization rate of organic materials in the greenhouse is high, increase the effective nutrients of the soil, improve the soil structure, fertilize the soil, and promote the development of beneficial microorganisms in the soilto inhibit the occurrence of vegetable diseases.

In order to facilitate water and fertilizer retention. For clay soil, it is recommended that vegetable farmers do not use rotary tillers to plough the ground, but to add sand to the soil before planting vegetables each time to reduce the stickiness of the soil, and at the same time turn the greenhouse soil deeply, and the depth of ploughing is 30 cm.

Of course, soil is crucial to vegetable yield, reasonable soil cultivation is very important for vegetable growth, if this step is done, followed by reasonable fertilization and watering, vegetables will inevitably have high yields.

Yes. In this way, the yield of crops will be increased, and at the same time, it will also be conducive to better growth of crops.

When growing vegetables, proper soil tillage is definitely an important factor in increasing yields, because soil is very important for crops.

Of course, because the vegetables grown in the right soil will have more nutritional value and the yield will be higher.

Yes, soil is an important factor in growing our vegetables, and it will give us a better yield and a particularly good quality.

I think that when we grow vegetables, choosing the right soil is an important factor to increase the yield, because it allows the plants to grow better and the nutrients are well absorbed.

<> "Three Uses for Growing Vegetables, Doubling the Yield of Growing Melons and Fruits."

1. Peanuts are fed to chickens and ducks to obtain chicken and duck manure.

Peanut cake is a very high nutritional value of the substance, containing almost all the nutrients in peanuts, and peanut cake is also a very fragrant substance, not only chickens, ducks, pigs and other poultry and livestock like to eat Yingchang Mountain, we can't help but want to eat.

2. Fermented composting.

In addition to feeding chickens and ducks, peanut cakes can also be directly used to ferment compost, only need to add some weeds, vegetable leaves, dead leaves, and pour in some brown sugar em bacteria liquid or em compost bacteria, stir evenly for sealed fermentation.

3. Make water and fertilizer.

In addition to the peanut cake can be fermented and composted with other materials, it can also be fermented separately with water and fertilizer, the method is very simple, that is, directly crush the peanut cake, put it into the fermentation tank, only need to fill one-third of the tank, and then add brown sugar em bacterial liquid and some brown sugar yeast liquid, and fill it with rice water, seal it up and ferment, about 50 days or so can be rotted well, if the weather is particularly hot, the fermentation will be faster, if the weather is cold, the fermentation will be slightly slower.

Knowledge of vegetable cultivation. I believe that everyone is no stranger to vegetables, we will eat all kinds of vegetables every day, most of the vegetables are artificially grown, many people want to know what knowledge of vegetable planting. Next, I will take you to learn more about vegetable planting knowledge.

1. Soil conditions

Vegetables are suitable for growing fertile and sufficient organic matter soil, when breeding vegetables, it is necessary to choose the soil with suitable pH according to the characteristics of the plant, and to plough the fine land to make it more soft and drainable, and to apply rotten organic fertilizer or compound fertilizer to the soil to promote the vigorous growth of vegetables.

2. Watering method

Vegetables like water, but not tolerant to waterlogging, when raising vegetables, you need to water according to the moisture of the soil, you can water once a week when there is no rain and drought, keep the soil moist, and during the rainy season you need to dig a drainage ditch, so that the water quickly flows out of the soil.

3. Topdressing fertilizer

Vegetables need sufficient nutrients in the growth process, when breeding vegetables, it is necessary to apply urea 2-3 times in the peak season of the plant to speed up its growth rate, and to spray foliar fertilizers such as potassium dihydrogen phosphate or superphosphate on the leaves of vegetables to increase the yield of plants.

4. Prevention and control of pests and diseases

Vegetables are susceptible to pests and diseases, when breeding vegetables, it is necessary to regularly observe the growth state of the plant, if you find pests on the leaves of vegetables, you should immediately use a paper towel to wipe it off, and to pull out the seriously infected vegetables, and to spray fungicides to promote the healthy growth of vegetables.

What are the varieties of vegetables grown in greenhouses?

1. Vegetables that can be grown in greenhouses

The vegetables that can be grown in greenhouses include tomatoes, cucumbers, eggplants, peppers, beans, lettuce, celery, rape, which are not easy to grow in winter, but with greenhouse planting technology, it perfectly solves this food problem and meets our winter vegetable needs.

2. The taste of greenhouse vegetables

The taste of greenhouse vegetables is actually no different from ordinary vegetables, but the vegetables grown in greenhouses are not easy to preserve, especially the vegetables that are transported long distances, are easy to rot, and the vegetables grown in greenhouses have less moisture than ordinary vegetables, so you will feel a little dry and hard, but eating vegetables grown in greenhouses will not threaten human health, don't think too much.

3. Fruits grown in greenhouses

Vegetables can also be grown in greenhouses, fruits can be grown in greenhouses: dragon fruit, blueberries, papaya, strawberries, watermelons, cherries, nectarines, fruits grown in greenhouses can allow us to eat these fruits all year round, and the taste is also very good, a lot of water, friends who like to eat fruits are feasting.

Leeks, artichokes, chayote, asparagus, lotus roots, toon sprouts, these belong to the single planting can be harvested for many years.

1 leek. This is one of the most well-known and well-known perennial vegetables in China. Leeks have been widely cultivated in our country since ancient times, and it has a strong adaptability and can be grown in both the north and the south.

2 chayote. It is a vegetable that was once common in the south, but is now rarely cultivated.

3 artichokes. Artichoke is not a ginger introduced from abroad, it is called devil ginger in the folk, or ginger, Wannian dirty, etc., and its scientific name is Jerusalem artichoke. It is a plant with flowers that resemble sunflowers, and underground rhizomes resemble ginger.

You can choose leeks, but you can also choose chayote, onions, asparagus, beans, eggplant, green peppers, red peppers.
