How much does it cost to grow soilless? Which vegetables are suitable for soilless cultivation?

Soilless culture is a cultivation technique that uses nutrients containing essential elements of plant growth and development to provide nutrients without natural soil, so that plants can complete the whole life cycle normally, greatly expanding the space for agricultural production, so that crops can be in the hairless Production on the ground, the development prospects are very extensive, the following Hui Nong network Xiaobian will introduce the soilless cultivation technology to the majority of growers!

1. How much does it cost to grow soilless?

Soilless culture has the characteristics of small investment and quick effect. The investment is mainly to build a greenhouse. The cost of greenhouses should be determined according to the actual situation. The cost of materials varies from 0.5 to 0.60 yuan per mu. The cost per acre of steel pipe greenhouses is about 0.8 to 0.9 million yuan. The cost per mu of cement greenhouses is about 1 yuan. ~ 15,000 yuan, the cost of a standard greenhouse in a greenhouse is 4 to 50,000 yuan. If the vegetables are cultivated, they can be marketed in one month, the cycle is short but effective, and the one-time investment will benefit for a long time.

2. What are the vegetables suitable for soilless cultivation?

1. Tomato: Soilless cultivation of tomatoes is generally carried out in a greenhouse, and this cultivation method can be carried out all year round. The soilless culture of tomato in the greenhouse can be determined according to the performance of the greenhouse. Generally, it is mainly produced in winter, spring and early spring.

2, bitter gourd: bitter gourd is a year-round climbing herb of the cucurbitaceae, stems, branches, petioles and pedicels covered with pilose, tendon tendrils, the conditions required for cultivation are not strict, the growth potential is strong, the fruit-bearing ability is strong, the harvesting time is long, very Suitable for soilless cultivation.

3, eggplant: eggplant in recent years using the solar greenhouse and greenhouse cultivation area is expanding, but due to continuous cropping, disease, especially soil-borne diseases occur seriously, the use of soilless cultivation can overcome this problem, has gradually become popular in recent years.

4, ginger: ginger using traditional planting mode continuous cropping because of the inability to remove residual nematodes and ginger mites in the soil, it is easy to infect ginger rickets, once infected with ginger rickets, a large piece of plants will wither and die, using soilless cultivation can solve this A problem.

5. Cucumber: Cucumber is often endangered by pests and diseases in production, while soilless cultivation can avoid soil-infected pests and diseases and continuous cropping obstacles. It also reduces pesticide dosage, improves crop yield and quality, saves fertilizer and labor, and is not restricted by land fertility. specialty.

Third, the advantages of soilless vegetables

1. It can increase the yield: the various nutrients required for crops in soilless culture are artificially formulated into nutrient solution. The nutrients can be scientifically supplied according to the crop species and the different growth stages of the same crop, so the crop grows robustly and grows. Strong.

2, the environment is clean and sanitary: soil-free cultivation is the application of inorganic fertilizers, while soil cultivation and application of organic fertilizers, fertilizer decomposition and fermentation, producing odors polluting the environment, will also cause many pest eggs to breed, endangering crops, so soilless cultivation is not There are these problems.

3, water-saving, fertilizer and labor: no soil cultivation does not require cultivating, tumbling, weeding and other operations, so it is more labor-saving. Watering and topdressing are solved at the same time, and the liquid supply system is regularly supplied quantitatively, which will not cause water and fertilizer 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, rational rotation of land and avoiding repeated years of heavy crops are one of the important measures to prevent serious occurrence and spread of diseases. However, soilless cultivation, especially hydroponics, fundamentally solves this problem.

5, not subject to soil restrictions: soilless cultivation makes the crop completely out of the soil environment, not restricted by soil quality and water conservancy conditions. Many deserts, wilderness or difficult-to-cultivate areas on the earth can be used without soil culture methods.

6. Make full use of space: Soilless cultivation can get rid of the constraints of the land, so it can be free from space constraints. It can be used to plant flowers on the flat roof of urban buildings, which can expand the cultivation area invisibly, and can also be produced according to people's will.
