Is the cost of soilless cultivation high, and how does the yield compare to ordinary cultivation met

1 Soilless cultivation is actually hydroponics, in which the roots of crops directly absorb nutrient solution and grow. In aeroponics, the nutrient solution is compressed into an air mist that is sprayed directly on the roots of the crop. The root system is suspended in the soilless classified part of the container space.

2. Substrate culture is one of the most widely used methods in soilless culture. Crop roots are fixed in organic or inorganic substrates, and crop nutrient solutions are provided through drip irrigation or drip irrigation through soilless cultivation. Due to the low investment and low cost, it has been widely used in production.

3. The soilless cultivation mode combining water and fertilizer is an intensive facility agriculture. In terms of cost, the average planting facility is about 80 sets, and the cost per square meter does not include the cost of greenhouses. However, labor input predominates, and product quality and output are higher than traditional models.

The soilless culture model also includes substrate cultivation.

The cost of soilless culture is relatively high; The yield is greatly improved compared to ordinary cultivation methods.

There is not much difference in yield, but they are grown differently and the yield will not be affected.

Conventional cultivation of crops, the root system is rooted in the soil layer that often has a good buffering effect, the soil layer is filled with water solution and air, the water and nutrients required for crop growth need to be absorbed through its root system, the inorganic and inorganic nutrients in the soil for crop growth should pass through the crop growth period, and the degree of soil moisture is difficult to grasp, often due to excessive watering, resulting in soil compaction, serious moisture accumulation, causing such and such diseases, the most important such as greenhouses, greenhouses for many years of continuous cropping, It will also make the number of soil-borne pests and diseases continue to increase the cost of this planting method is relatively high, but because it can provide the most suitable nutrient conditions for plants, the yield is very high, but the requirements of soilless culture on capital, equipment, technology, etc. are relatively high, and only a few vegetables and fruits and precious flowers have been used in recent years, and soilless cultivation technology is widely used in agriculture. Soilless cultivation has many advantages over conventional cultivation techniques.

It can realize the green organic cultivation of vegetables, factory planting, and does not depend on the influence of external weather, and is not affected by largeThe difference between soilless culture and conventional cultivation is that plants are cultivated directly with nutrient solution without soil. In order to fix the plants and increase the air content, most of them use gravel, sand, peat, vermiculite, perlite, rock wool, sawdust, etc. as the fixed substrate. Its greenhouse, seedbed, production equipment, water supply system, etc., so the input is relatively much larger, and conventional cultivation can have suitable production conditions, the difference is two, the choice of planting varieties is not the same, the current soilless cultivation is mainly planted with leafy vegetables, and more choices are grown in the case of low productivity in the primitive society, mainly by picking fruits to satisfy hunger.

However, due to various uncertainties, wild fruits simply cannot meet people's needs, which forces people to constantly find ways to obtain more abundant food. Therefore, wild soilless cultivation refers to the cultivation method of using substrate instead of natural soil or substrate only for seedling raising, and irrigating with nutrient solution after planting. Because soilless cultivation can artificially create a good rhizosphere environment to replace the soil environment, it can effectively prevent soil continuous cropping diseases.

The cost of soil cultivation is lower, because soil cultivation only requires soil and fertilizer, while soilless cultivation requires the preparation of nutrient solution, which is very expensive.

Naturally, soil cultivation is less costly, as soilless cultivation requires the preparation of a nutrient solution compared to soil cultivation. And because soilless culture does not have the role of fixing the root system, it is necessary to build a scaffold to fix the plant. These come at a high cost.

The production volume of soilless cultivation technology is very high. Traditionally, the soil is made up of minerals, nutrients and organic matter, which is gradually transformed into a rich soil layer. However, not all soil layers are abundant, so in order to better allow plants to grow and develop, we should add chemical pesticides to fertilize the soil layer.

Soilless cultivation technology is a planting method with zero pollution, no organic chemical humus, and no soil layer. This is an essential nutrient for the immediate delivery of green plants to their development using the culture medium. In short, soilless cultivation is a new type of planting technology that does not require a soil layer, but simply replaces the soil layer with a variety of other cultivation media.

In recent years, soilless cultivation technology has been slowly developing in all parts of the country, compared with traditional soil layer planting, soilless cultivation technology can prevent continuous cropping obstacles such as vine blight disease, and at the same time has the characteristics of reducing the dose of chemical fertilizer, improving crop yield and product quality. At this stage, 70% of the production and manufacturing of greenhouse crops in capitalist countries are all based on soilless cultivation technology.

The characteristics of soilless cultivation of vegetables are: rapid growth and development of seedlings, short seedling age, good rhizome development, strong and neat seedlings, short root delay time after transplanting, and high survival rate. Whether it is a pre-seedling of the cultivation medium or the pre-seedling of the culture medium, it can ensure that the supply of water and nutrients is abundant, and the cultivation medium has excellent ventilation.

At the same time, soilless seedlings are conducive to scientific, rational and standardized management. After transplanting, the allelopathic natural environment is consistent with the allelopathic natural environment during the pre-seedling, because the rhizome is well developed, the roots are not damaged after transplanting, and it is easy to survive, and there is generally no slow seedling stage.

The vast majority of the soilless cultivation technology is all inorganic fertilizer, which has no peculiar smell and does not use manure places. The soil layer is planted and applied with organic fertilizer, and the organic fertilizer dissolves and produces alcohol, causing odor and environmental pollution, or it will breed many insect larvae and harm vegetables and fruits, while soilless cultivation technology will not have these points. Especially in the cultivation of vegetables, fruits and flowers on the indoor balcony, daily cleaning is stipulated, and the soilless cultivation technology is both clean and environmentally friendly.

Soilless cultivation does not require a soil layer, while conventional cultivation requires a soil layer. Soilless culture uses the culture medium to directly deliver nutrients to green plants, and the yield is higher than that of conventional ones.

Soilless cultivation technology is not to use soil as a necessary condition for cultivation, there are mainly substrate cultivation, hydroponics, aeroponics three ways, conventional planting, can reduce labor, but also reduce heavy manual labor, conventional cultivation needs to plough the land, land preparation to do furrowing, cultivating loose soil hoeing and many other work, during which it takes a lot of artificial time.

Friends who know know that the cost of soilless cultivation is much higher than that of soil cultivation, and it needs to be specified in soil nutrition, humidity, temperature, and technology is also higher than the requirements of soil cultivation, after all, there is more manual intervention, so soilless plants are generally high value-added plants. But why is soilless cultivation technology valued by the state and welcomed by the masses?

First. The substrate is taken from cheap crop stalks, corn cobs, waste mushroom residues and other agricultural wastes, which fully replace the most expensive grass peats as soilless cultivation substrates, and can be used continuously for 3 4 years.

Second. Soilless cultivation breaks through the traditional notion that chemical nutrient solutions must be used. It uses organic solid fertilizer instead of chemical nutrient solution, and only needs to irrigate water during the whole growth process of the crop, reducing the consumption of labor and materials.

Third. According to the long-term depreciation to calculate the cost of soilless culture, in general, the cost is not high, mainly because of the high yield of soilless culture, taking the Netherlands as an example, the annual output of soilless tomato is about 52kg per square meter, and the annual output of soilless soil cultivation is only 22kg; The annual output of cucumbers per square meter is about 70kg in soilless culture, and only 25kg in soil cultivation. At the same time, the rate of A-grade soil cultivation is more than 94%, and soil cultivation is only about 20%.

The rate of A-grade products in soilless culture is more than 94%, and that of soil cultivation is only about 20%. Fourth. Soilless cultivation frees agricultural production from the constraints of the natural environment and allows it to be produced according to human will, so it is a controlled agricultural production method.

To a large extent, farming according to quantitative indicators is conducive to the realization of mechanization and automation, so as to gradually move towards an industrialized mode of production.

In short, from the yield and quality of soilless culture, the cost and benefit are proportional, just like the manufacturing industry, the initial investment is high, the long-term operation return is large, and the most important thing is that clean and pollution-free vegetables are in line with people's growing healthy and green food culture.

Soilless cultivation does not mean that the importance of land is declining, soilless cultivation is for the better development of agriculture, but Qingqing is the land is vital to agriculture, and it will change if you do not respond to the land.

Soilless cultivation is the use of other substances to replace soil planting, reducing the harm of soil spitting disease, which does not mean that the importance of land to agricultural production is declining, because some crops are not suitable for soilless cultivation, and the soilless cultivation of Cong Xiao cost seepage vertical draft is relatively large.

Soilless cultivation is definitely the importance of agricultural production will decline, and the cultivation of good soil and limbs is a high-tech staring for the future, so there will be a big gap for ordinary cultivation.

Soilless cultivation is a new type of agricultural model, but this does not mean that the importance of land to agricultural production has declined, and land is still the most important part of agricultural production. Hui Fangqing.

The investment is mainly to build greenhouses, the south needs about 5,000 yuan to build an acre of greenhouses, about 12,000 yuan in the north, the existing melon and vegetable flowers can be used directly, one acre only needs to invest about 1,500 yuan, and the investment in melons and vegetables will not increase compared to ordinary greenhouses. Vegetables can be marketed in one month, and the cycle is short and effective.

The cost is higher than that of conventional soil cultivation, mainly operating expenses (water and electricity), substrate materials, cultivation facilities and equipment, etc.].

The cost of soilless cultivation is n times higher than that of conventional cultivation, and the technical conditions for the configuration of nutrients are harsh. If the technology is passed and the management is good, the yield will be higher than that of traditional cultivation. However, if the product is sold according to the best of traditional cultivated products, it will not be able to recover the planting cost, let alone make a profit.

There are two main barriers to increasing sales**. First, it is difficult to meet the national green vegetable standards; The second is (even if the standard is reached) there is no market in China's current small and medium-sized towns, especially in the rural areas (that is, ordinary people can buy it). Among them, the technical difficulty has limited the development of this cultivation technology to individual farmers. ]

If we continue to engage in nutrient solution pure chemical fertilizer agriculture, the development prospect of soilless culture is very slim, so the development of organic agriculture and sustainable agriculture is the subject to be studied. "Four seasons efficient ecological soilless cultivation technology" is the latest scientific and technological achievements made by our unit, the technology uses a variety of crops of straw, rice husk, waste mushroom residue, bark, domestic garbage and other organic matter, after technical treatment, and then add their own organic fertilizer to make it into the substrate of cultivated vegetables, the substrate releases organic nutrients instead of inorganic nutrient solution to supply nutrients of an agricultural high-tech. It has significant advantages such as low investment cost, simple operation, easy management, water and fertilizer saving, less labor, no continuous cropping obstacles, high yield and high quality.

It reduces the complex work of preparation, adjustment, circulation, monitoring and management of the traditional soilless cultivation nutrient solution, and overcomes the disadvantages of high investment cost, high production cost and poor product quality of the nutrient solution soilless culture, and is suitable for large-area production.

High-efficiency substrate for all seasons: raw materials are widely available, low cost and easy to make. "Four seasons efficient substrate" through fine production, rich and complete nutrition, good permeability, conducive to root growth, and clean and hygienic without pests and diseases, and can release nutrients in a timely manner, is the "source" of nutrients needed for plant growth, is the "library" of storage and regulation of nutrients and water, is the "base" to support the growth of vegetables, and can be used continuously for 3 5 years, a long-term benefit of investment.

Organic substrate is a solid substance containing various nutrients, and the release of nutrients after technical treatment is slow and long-lasting, and at the same time, fast-acting organic fertilizer is added, and then inorganic matter is added, so that the cultivation substrate can achieve comprehensive, rich, sufficient and long-lasting nutrition, and at the same time, the air permeability and water retention are good, and the root system grows well. In this way, the vegetative growth and reproductive growth of vegetables reach a balance, vegetables can hang fruit 7-15 days in advance, the fruit growth cycle is short, the full fruit period of vegetables is extended, the comprehensive yield is 2-5 times that of soil planting, and the annual yield of tomatoes and cucumbers per mu can reach 3-50,000 catties.

Soil planting and nutrient solution soilless cultivation is the use of various chemical fertilizers to produce vegetables, resulting in the content of nitrate in vegetables seriously exceeding, after people eat vegetables with excessive nitrate, nitrate accumulates in the human body, inducing the occurrence of various diseases. The nutrients required by vegetables in this technology are obtained by decomposing organic matter; At the same time, the content of vitamins, sugars and amino acids in vegetables is 15%-30% higher than the green standard, and the quality is higher than the green standard and is conducive to human health. The ** of general green organic vegetables is 2-3 times that of ordinary vegetables, and the ** of foreign green organic vegetables is more than 3-5 times higher than that of ordinary vegetables, and the price is as high as more than 100 yuan per catty, and the value-added space is huge.

With the growth of people in plants extremely.

At the same time, with the rapid development of petrochemical industry, the large number of plastic products used in soilless cultivation such as pipes, plastic films, etc. has been greatly reduced, so that the cost of soilless cultivation has been reduced to the level of large-scale construction that is acceptable to many growers; At the same time, due to the application of water pumps, solenoid valves, timers, acidity meters, conductivity and electronic computers and other control instruments required for automatic control, the production process of soilless cultivation is gradually mechanized and automated, and the production scale is expanding day by day.
