Can the soil used for construction in rural fields be used to grow vegetables?

You need to clean it upBackfillin the stonesConstruction wasteand other more obvious impurities. It is not appropriate to call these things impurities, because these things are obviously different from the physical and chemical properties of the soil, and cannot be used for agricultural production at all. After the plot is reclaimed or backfilled, it should be carried out to remove impurities, flood, dry the land, rake, and dry the land again.

When planting crops for the first time or in the first two or three years, dwarf crops should be selected, such as various vegetables, dwarf stems, ground climbing vine crops, etc.

<> If possible, pick out the fertile soil in the backfill and spread it on the surface of the backfill. The soil that has just been backfilled will be relatively solid, so it is recommended to use more farm fertilizer, if the soil is more and more solid with chemical fertilizer, and more farm fertilizer will make the soil fertile, you can also send the soil to plant vegetables is very beneficial, during the planting of vegetables, the area of planting vegetables should be small at the beginning of the first one or two stubbles, so that the soil and the vegetables that are planted slowly adapt to such a planting and growth environment, and slowly let the backfill become raw soil.

Construction waste, for example, when you demolish the house, those masonry and cement blocks cannot be used to grow vegetables. It can only be used exclusively for backfilling. Planting vegetables in backfill soil requires a good job of loosening the soil, mainly because the backfill soil is easy to compact.

In addition, the backfill absorbs a large amount of water, so during the management period, more water is required. The trace demand is iron, copper, manganese, zinc, boron, molybdenum, chlorine, which is what we often call trace elements.

Demand <.

If the amount of use is relatively large and the economic conditions do not allow, you can do it yourself to turn out the garbage and stones in the soil and dispose of them, and then plant them to make green manure.

Things such as peanuts, corn, potatoes, etc., after harvesting, when turned into the ground, the current vegetables have a strong ability to resist diseases and insects and grow ability. In the first three years, you can apply more organic fertilizer from the farm, and you can also apply chemical fertilizer. Using vegetable roots and weeds a few more times can transform the soil into fertile soil.

Absolutely, this is a particularly good soil, you can grow very good vegetables, such vegetables are also very delicious, crispy, sweet.

The soil used for construction in the field can not be used to grow vegetables, these soils are very lacking in nutrients, and if you grow vegetables, the development of vegetables will not be particularly good, so if you grow vegetables, you still have to find some fertile soil to plant.

If it's just bricks or stones, you can grow vegetables. If there is a lot of gypsum powder in it, the food will not be able to live, because this kind of thing will heat up when it is exposed to water, and the food will be burned.

Not really. This soil has no nutrients and is lifeless, so it is not possible to grow vegetables.

Of course, the following crops can be planted on basic farmland: grain and oil crops, various vegetables, and various melons that are in short supply per liter, strawberries,Dwarf plants such as herbaceous flowers, Chinese medicinal materials, and pastures can be used as fruit tree nurseries, planting edible fungi, etc. The construction of permanent greenhouses on basic farmland to grow vegetables requires approval from the local authorities. Raids.

Please note if you are:Basic farmland, replanting what is limited by celery.

In principle, those who grow grain cannot be changed to non-grain, but they can adopt the land use method of intercropping, crop rotation, and intercropping between grain and non-grain crops, but at least one season of grain crops can be planted on the cultivated land every year. Specifically, you can learn about the "Opinions of the General Office of the People's Republic of China on Preventing the "Non-Grain" of Cultivated Land and Stabilizing Grain Production.

To be safe, you should ask your local authorities, not your sailors online.

Loosen the soil first, then dig the ground.

First, the steps of novice planting vegetables:

1. First of all, you need to find a piece of land suitable for your own cultivation, and choose the size of the land to grow vegetables.

2. Then use a hoe.

Loosen the soil, constantly turning the soil up and removing some weeds.

3. Sow seeds, dig small soil pits of suitable size in the land, put the seeds in, and water them.

4. After treatment, pay attention to watering and weeding every day.

2. What other skills do farmers have for growing vegetables?

For vegetables, fertilizer is very important and indispensable. For experienced vegetable farmers, they have accumulated a lot of experience in production practice, which can be summarized as vegetable fertilization, sky fertilization, and fertilizer fertilization. Let's take a look at how to do it.

1. Watch the vegetables and fertilize.

Different varieties of vegetables, the amount of fertilizer is not the same, if the fruit and vegetables and melons are planted, in addition to nitrogen fertilizer, phosphorus and potassium fertilizers are also needed, and the soil chef can be used to polymerize potassium dihydrogen phosphate.

Phosphorus and potassium supplementation.

2. Look at the sky and fertilize.

The main factors that influence fertilization are climatic factors such as temperature, precipitation, and light. When the temperature is high, the crop grows vigorously and requires more fertilizer, so more fertilizer can be applied in the growing season when the temperature is suitable, and less or no fertilizer can be applied in the low temperature season.

3. Look at fertilizer and fertilization.

In the process of fertilization of vegetable planting, inorganic fertilizer and organic fertilizer are gathered, organic fertilizer is used as base fertilizer and top dressing, most of the inorganic fertilizer is used as top dressing, and in some cases, inorganic fertilizer is used as base fertilizer.

In addition to soil fertilization, vegetable planting can also be topdressing outside the roots. However, it is better to use chemical fertilizers of pure quality that do not easily cauterize the foliage.

Urea is more commonly used.

Soil chef polymerizes potassium dihydrogen phosphate, as well as trace element fertilizers.

Loosen the soil first, then dig a pit, sow seeds, then cover the soil, water it, and fertilize it.

Crop rotation refers to the cultivation method of rotating vegetables with different properties on the same soil for a certain number of years. Crop rotation and continuous cropping are relative. Continuous cropping, on the other hand, refers to the cultivation of the same crop or other crops of the same family on the same soil for a long time or in successive years.

If the same soil is always planted with the same or other types of vegetables in the same family, the soil quality will become worse and worse, and the plant pests and diseases will become more and more serious.

Because the pests and diseases that other types of vegetables in the same family are susceptible to are basically the same. Therefore, when we grow vegetables, we should implement the cultivation method of crop rotation, and plant vegetables of different families in the same soil, so that the invasion of vegetables by pests and diseases will be greatly reduced. Moreover, different families of vegetables have different requirements for nutrients in the soil, and crop rotation will not over-deplete certain nutrients in the soil.

Crop rotation can make full use of soil fertility, reduce the probability of vegetables encountering pests and diseases, and help vegetables thrive. Let's take a closer look at crop rotation.

Different vegetables require different nutrients. Generally speaking, leafy vegetables such as spinach and lettuce need more nitrogen fertilizer, eggplant vegetables such as peppers and tomatoes need more phosphorus fertilizer, and root vegetables such as sweet potatoes and potatoes have a high demand for potassium fertilizer. Therefore, these three types of vegetables can be rotated, and some nightshade vegetables with more phosphorus can be planted after planting leafy vegetables that require more nitrogen.

If leafy vegetables that require more nitrogen are always planted in the same soil, over time, soil fertility will decline, nutrients will be imbalanced, and it will be difficult for vegetables to grow healthily.

Different vegetables absorb fertilizers at different rates. In general, celery, spinach, cucumbers, etc. absorb fertilizer faster, and tomatoes, peppers, eggplants, etc. absorb fertilizer slowly. When the rotation tactic is implemented, the vegetables that absorb fertilizer quickly can be planted in rotation with those that absorb fertilizer slowly, so as to make full use of the fertility in the soil.

Some vegetables have deep roots, some are shallow, and if we rotate vegetables with different root depths, different levels of nutrients in the soil can be fully absorbed. In general, beans, melons, and root vegetables have deeper roots, while onions, garlic, and leafy vegetables have shallow roots.

Different vegetables have different pH requirements for the soil during the growth process. For example, the soil acidity will be reduced after planting pumpkin and corn, and onion vegetables are more sensitive to acidic soil. After planting cabbage and potatoes, the soil acidity will increase, and if you plant onions and vegetables at this time, the yield will be greatly reduced.

For example, if Chinese cabbage is planted after planting onions and garlic, the probability of soft cabbage rot can be greatly reduced; After planting cucumbers, it is best to rotate some non-melon and fruit vegetables, which can effectively inhibit pests and diseases.

Different types of vegetables have different inhibitory effects on weeds in the soil. Vegetables such as celery, onions and carrots have small leaves and slow emergence, and weeds are easy to grow in the soil where they are grown. Choose vegetables with larger leaves and fast growth, such as kale, potatoes, melons and beans.

These vegetables are planted at a high density and have a large leaf covering force on the ground, which can effectively suppress weeds.

If you continue to grow vegetables, it may cause the vegetables to rot and die and cause losses, so at this time, it is better to disinfect the land, or choose a new land to grow vegetables, which will be more certain.

If the soil of the vegetables is damaged, we can also continue to plant other vegetables, after all, it may be because of the wrong way to plant that there is no harvest, we need to change the other varieties will be fine.

If the soil that has been planted with vegetables is too dry or too wet to cause the plants to die, you can continue to plant other vegetables.

If it is bad, it is better not to plant other vegetables in the soil of the vegetables, because it is possible that other vegetables will not be able to continue to grow, so it should be necessary to pay attention to it for a while.

If the soil of the vegetable is damaged, it should be best not to pick up this other vegetable, because it may also be damaged, or it may be that it is not ripe for other vegetables.

If the soil of the vegetables is damaged, the pH may not be suitable, and the vegetables need to be readjusted. Vegetables will also die.

If I have damaged the soil of the vegetables, can I inoculate other vegetables? So you have to see if the soil still has nutrients? If you don't have nutrients, do you think it's okay to eat other vegetables?

By turning the soil, you can use the sun's ultraviolet rays.

Killing and killing pests and eggs stored in the soil makes the next loss of vegetables less susceptible to pests and diseases, less need to use pesticides, and it is more safe to eat by yourself. Second, by turning the soil, the land that was originally built into wooden planks becomes soft and fertile, which is conducive to the rooting and growth of thinning vegetables and increasing yield. Third, the root system of each sparse vegetable is different.

A sparse vegetable like an eggplant has the same root system as a small sapling. If the root system is not destroyed by tilling, the next thinning vegetable will not be able to absorb nutrients and die.

Heavy will grow eggplant young leaves, planting a piece of sparse vegetables winter ploughing is a common agricultural operation in the past, but now many farmers have omitted this step, which is the same reason as the steaming scaffold, the steaming shelf is in summer, using the high temperature of organic fertilizer fermentation, while reducing pests and diseases in the soil, while fertilizing the soil. In fact, there are many benefits of arriving land in winter. A large amount of land is planted continuously, coupled with the irrational application of chemical fertilizers, and a large amount of non-degradable substances remain in the soil.

There may be knots, watering and fertilization can only be on the surface, the utilization rate is not high, after turning the soil, the soil below is turned over, the structure of the soil is improved, the soil is loose, which is conducive to the growth of crops, and the plants that change the soil moisture like to grow in a humid environment, but the soil is too dry to be conducive to the growth of crops. Therefore, to change the paving and loosening of the soil, it is necessary to use the cultivation of the soil to make up for the shortcomings, if the soil is too sticky, the humidity will become high, the air permeability will become poor, which is not conducive to the growth of crops, and is prone to root rot and other viral diseases.

On the other hand, when the soil is too loose and the water-holding and fertilizing ability is poor, fertilization should be carried out to improve soil viscosity and promote crop harvest. According to the depth of root penetration, distribution breadth, number of branches, and root hair development, the soil nutrient absorption of various vegetables is large and small.

This can be disinfected and sterilized, the soil can become more soft, and the drainage can be better, the purpose of this is to make the plants grow better.

The main purpose is to create good planting conditions, which can be disinfected and sterilized, and fertility can also be improved. The main thing is to ensure the nutrients of the soil, which can kill the bacteria in the soil.

In this way, the fertility of the soil can be guaranteed, and then the soil can be made more crisp, and then the temperature can be increased, which can reduce the temperature of the soil, and then the seeds can be better breathed.

Balcony planting can choose soilless cultivation, using rock wool, peat, vermiculite, water and other substrates plus nutrient solution cultivation; Or choose humus soil, which can be mixed with garden soil; You can also choose coir bricks, which are crushed and planted after soaking; Garden soil is more common, which is more fertile; Or use peat soil, pond mud, etc.

1. Soilless cultivation.

In short, soilless cultivation is the technique of cultivating plants with nutrient solution without using soil, including rock wool, peat, vermiculite, perlite, bark, sawdust, water, etc. Plants cultivated without soil grow quickly, have relatively high yields, are of good quality, clean and have few pests and diseases, and are easy to manage. To supplement nutrients, you can choose to spray fertilized leaf amino acid foliar fertilizer.

2. Humus.

Humus soil is made of deciduous leaves, withered grass and other substances accumulated and fermented, and can be mixed with garden soil when used, and put away after screening and drying. Humus soil is rich in humus, good fertility and drainage, and light and loose.

3. Coir bricks.

When using, put the coir bricks in a basin or bucket and pour enough water until the coconut bricks no longer absorb water. Pour out the excess water, put the soaked coconut soil into the planting container, crush the coconut soil and mix it with vermicompost manure, and apply a small amount of organic compound fertilizer in the soil as the base fertilizer. Sprinkle the seeds on the surface and cover the soil shallowly, just keep the soil moist before germination, and do not water too much.

4. Garden soil. Garden soil is the soil used for planting in vegetable gardens or nurseries, which is relatively fertile and can be used after disinfection.

5. Peatland.

Peat soils are best mixed with perlite or vermiculite, as these substrates can increase soil porosity and beautify the soil.

6. Pond mud. The pond mud has a lot of fertilizer and good drainage, and it is best to dry the pond mud after digging it out, and break it into thin pieces during use.
