How much is the latest soilless cultivation?

Soilless cultivation is a kind of cultivation technique that uses nutrient solution containing essential elements for plant growth and development without natural soil to provide nutrition, which enables plants to complete the whole life cycle normally, which greatly expands the space of agricultural production. Crops can be produced in barren land, and the development prospect is very broad. Let's take a look at the general investment in soilless cultivation.

How much is generally invested in soilless cultivation?

Soilless cultivation has the characteristics of small investment and quick effect, and the investment is mainly to build a greenhouse. The cost of greenhouse should be determined according to the actual situation, and the cost varies with different materials. generally, the cost of bamboo greenhouse is about 0.5 ~ 6000 yuan per mu, steel pipe greenhouse is about 0.8 ~ 9000 yuan per mu, cement greenhouse is about 1 ~ 15000 yuan per mu, and the cost of standard solar greenhouse is 40 ~ 50, 000 yuan per mu. If vegetables are cultivated, they can be put on the market within a month, with short cycle and quick effect, and long-term benefit from one-time investment.

What are the vegetables grown in soilless culture?

1. Tomato: soilless cultivation of tomato is generally carried out in greenhouse, and this cultivation method can be carried out all the year round. Soilless cultivation of tomato in solar greenhouse can determine the arrangement of stubble according to the performance of greenhouse, which is mainly produced in winter and spring and early spring.

2. Balsam pear: bitter gourd is an annual climbing herb of Cucurbitaceae, with pilose stems, branches, petioles and pedicels, axillary tendrils, lax conditions for cultivation, vigorous growth, strong fruit setting ability and long harvest time, so it is very suitable for soilless cultivation.

3. Eggplant: the area of eggplant cultivated in solar greenhouse and greenhouse has been expanding in recent years, but due to continuous cropping, diseases, especially soil-borne diseases, are serious. Soilless cultivation can overcome this problem, and it has gradually become popular in recent years.

4. Ginger: the traditional planting mode of continuous cropping of ginger can not remove the residual nematodes and ginger blast pathogens in the soil, so it is easy to be infected with ginger blast. Once infected with ginger blast, a large area of plants will wither and die. Soilless cultivation can solve this problem.

5. Cucumber: cucumber is often harmed by diseases and insect pests in production, but soilless cultivation can avoid diseases and insect pests and continuous cropping obstacles caused by soil infection. it also has the characteristics of reducing pesticide dosage, improving crop yield and quality, saving fertilizer and labor, and is not restricted by land fertility.

Advantages of soilless cultivation of vegetables

1. It can increase yield: all kinds of nutrient elements needed by crops in soilless cultivation are artificially prepared and applied into nutrient solution, and nutrients can be supplied scientifically according to crop types and different growth stages of the same crop, so crops grow and develop healthily. Strong growth.

2. The environment is clean and hygienic: soilless cultivation uses inorganic fertilizer, while soilless cultivation applies organic fertilizer, fertilizer decomposition and fermentation, which not only produces odor to pollute the environment, but also causes the egg breeding of many insect pests and harms crops, so soilless cultivation does not have these problems.

3. Water-saving, fertilizer-saving and labor-saving: soilless cultivation does not require ploughing, ploughing, weeding and other operations. Watering and topdressing is solved at the same time, and it is supplied regularly and quantitatively by the liquid supply system, which will not cause waste, and the management is very convenient, which greatly reduces the labor intensity.

4. Avoiding continuous cropping obstacles: in the field planting management of vegetables, reasonable land rotation and avoiding continuous cropping is one of the important measures to prevent the serious occurrence and spread of diseases. Soilless cultivation, especially hydroponics, has fundamentally solved this problem.

5. free from soil restrictions: soilless cultivation makes crops completely out of the soil environment and is not limited by soil quality and water conservancy conditions. soilless cultivation can be used in many deserts, wastelands or areas where it is difficult to cultivate.

6. make full use of space: soilless cultivation can get rid of the constraints of the land, so it can not be restricted by space, and can use the flat roof of urban buildings to grow vegetables and flowers, virtually expanding the cultivation area, and can also be produced according to the will of people.
