The yield of soilless cultivation is several times that of traditional cultivation?

Understanding of planting friends know that soilless cultivation is much more expensive than soil cultivation, it needs to specify soil nutrition, humidity, temperature, technology is also higher than soil cultivation requirements, after all, there are more manual intervention, so soilless plants are generally high added value plants. But why will soilless cultivation be valued by the country and welcomed by the masses?

First, the substrate is made of cheap crop straw, corncob, waste mushroom residue and other agricultural waste to replace the expensive grass as a soilless cultivation substrate, and can be used continuously for 3 to 4 years.

Second, soilless cultivation breaks through the traditional concept that chemical nutrient solution must be used. It uses organic solid fertilizer instead of chemical nutrient solution, and only needs to irrigate water during the entire growth process of crops, reducing the consumption of labor and materials.

Third, according to the long-term depreciation to calculate the cost of soilless cultivation, generally speaking, the cost is not high, mainly because of the high yield of soilless cultivation, taking the Netherlands as an example, the annual output of soilless cultivation tomatoes per square meter is about 52kg, soil cultivation is only 22kg; The annual output of cucumbers per square meter of soilless cultivation is about 70kg, and soil cultivation is only 25kg, so although the initial input cost is large, the production cost is falling every year, and the profit is constantly improving. At the same time, the rate of grade A in soilless cultivation is more than 94%, and soil cultivation is only about 20%.

Fourth, soilless cultivation makes agricultural production get rid of the constraints of the natural environment, so that it can be produced according to the will of people, so it is a controlled agricultural production mode. To a large extent, farming according to quantitative indicators is conducive to the realization of mechanization and automation, so as to gradually move toward industrial production mode.

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