The cost of soilless culture is much higher than that of soil culture, and it requires higher soil nutrition, humidity, temperature and technology. After all, many natural products are artificial products, so soilless plants are generally high value-added plants.

Soilless culture is a modern agricultural technology with high technology content, high input, high output and high benefit. With the reliable technical support, the products produced by soilless culture technology have the advantages of high yield and good quality. Protection facilities such as greenhouses or greenhouses are used to control environmental conditions for off-season (off-season) production. Putting these high-grade vegetables and fruits into the market can achieve good economic benefits.

Increasing crop yield, improving crop quality and striving for anti-season cultivation is an important aspect to improve the economic benefits of soilless culture. On the other hand, in order to obtain better economic benefits, it is necessary to arrange stubble reasonably according to market conditions and local climate conditions, so that soilless culture facilities can produce in a balanced way all year round. At the same time, it is necessary to have a certain scale of production to produce scale benefits. On the basis of a certain scale, reducing infrastructure investment, mobilizing the enthusiasm of managers and production employees, reducing production costs and tapping the potential of enterprises has reflected its high economic benefits in many aspects as a whole.

Cost composition of soilless culture production

1, infrastructure investment

Including the construction cost of building facilities for production purposes, the purchase cost of equipment commonly used in production, such as small acidity meter, conductivity meter, small means of transport and other production tools, land rent or land acquisition costs. The sum of these facilities, equipment construction and purchase costs and land rent is the direct investment cost of soilless culture production. Allocating the annual direct investment expenses according to the service life of facilities under construction, or according to the economic depreciation period determined for accelerating investment recovery, which is usually shorter than the actual service life of facilities and equipment, is called annual depreciation expenses. The direct investment cost of soilless culture production base or enterprise also includes the loan interest of funds.

2. Direct production costs

Refers to the expenses directly used in the production process of soilless culture, including:

(1) Fertilizer cost: refers to the cost of fertilizer consumed in the production process.

(2) Seedling planting cost: the cost of purchasing seeds and seedlings.

(3) Water and electricity costs: the cost of irrigation or nutrient solution circulation during crop planting, and the management cost of domestic water and electricity for employees.

(4) Pesticide cost: the cost of placing pests and diseases and disinfection facilities and equipment.

(5) Employee salaries: the salaries of employees who manage and operate soilless culture production.

(6) Other expenses: such as daily maintenance of greenhouses or greenhouses, support of crop vines, etc.

3. Cost of sales

Various expenses used in the marketing of soilless culture products, including advertising expenses, product packaging expenses, transportation expenses, loss of products during transportation and sales and other sales expenses.

4. Unexpected expenses

All kinds of unforeseen expenses that occurred in the process of product production and sales and were not mentioned in the above expenses. Such as losses caused by disastrous weather or losses caused by other reasons.

The total cost of the above four categories is the total production cost of the whole production base or enterprise. The economic accounting of soilless culture production base can account for one or several crops, annual accounting, and total accounting of economic benefits of several production cycles, which can be determined according to the financial system of each enterprise. Generally, annual economic accounting or economic accounting of one or more crops is carried out.

This is a one-time investment, and it is very high.

The difference between soilless culture and conventional culture is that plants are cultivated directly with nutrient solution without soil. In order to fix plants and increase air content, gravel, sand, peat, vermiculite, perlite, rock wool and sawdust are mostly used as fixing substrates. Its advantages can effectively control the best requirements of flowers for temperature, moisture, light, nutrients and air in the process of growth and development. Because soilless cultivation of flowers does not use soil, it can expand the planting scope, accelerate the growth of flowers, improve the quality of flowers, save fertilizer and water, save manual operation and labor and cost. The disadvantage is that the one-time investment is large and additional equipment is needed. If the nutrient source is polluted, it is easy to spread, and the preparation of nutrient solution requires technical knowledge.
