Soilless culture nutrient solution formula Soilless culture technology where to learn

Soilless cultivation must be no stranger to many people, recently you are very common in our country, but also a mature cultivation technique. One of the most important aspects of soilless cultivation is the proportion of nutrient solution, which also has some tips. Now there are still many people who want to learn soilless cultivation techniques, but they don't know where to learn them. Let's take a look.

Formula of nutrient solution for soilless cultivation

1. Formula 1: urea 5g, potassium dihydrogen phosphate 3g, calcium sulfate 1g, magnesium sulfate 0.5g, zinc sulfate 0.001 g, ferric sulfate 0.003 g, copper sulfate 0.001 g, manganese sulfate 0.003 g, boric acid powder 0.002 g dissolved in 10 kg water.

2. Formula 2: ammonium nitrate 0.2g, calcium superphosphate 0.6g, potassium nitrate 0.55g, magnesium sulfate 0.54g, calcium sulfate 0.08g, ferrous sulfate 0.003 g, manganese sulfate 0.002 g, boric acid 0.003 g, zinc sulfate 0.002 g, ammonium molybdate 0.002 g dissolved in 2 kg water.

3. Formula 3: potassium nitrate 0.7g, calcium nitrate 0.7g, calcium superphosphate 0.8g, magnesium sulfate 0.28g, ferric sulfate 0.12g, boric acid 0.0006 g, manganese sulfate 0.0006 g, zinc sulfate 0.0006 g, copper sulfate 0.0006 g, ammonium molybdate 0.0006 g dissolved in water.

Formula 4: calcium nitrate 0.8g, potassium nitrate 0.04g, potassium dihydrogen phosphate 0.25g, magnesium sulfate 0.40g, ferrous sulfate 0.015 g, manganese sulfate 0.004 g, boric acid 0.006 g, zinc sulfate 0.0002 g, copper sulfate 0.001 g, ammonium molybdate 0.0002 g dissolved in water.

How to learn soilless cultivation techniques

Soilless cultivation techniques can generally be learned in agricultural bases, each identity of the place is different, so we should go to the local consultation. The tuition fee for learning this technology is generally about 5000-8000, but the price will be different in different provinces and regions. It usually takes about 2-3 months to learn this technique, but it also depends on the individual learning process.

Application of soilless cultivation

Because soilless cultivation gets rid of the restriction of soil cultivation, it has a broad development prospect. Soilless cultivation has a wide range of applications, mainly in the following aspects:

1. Used for vegetable cultivation. Plant factory hydroponic vegetables to cultivate pollution-free green food, health and safety, by people's attention.

2. Used for flower cultivation. Whether cut flowers or potted flowers are first suitable for soilless cultivation, soilless cultivation of flowers not only have large heads, but also bright colors.

3. It is used to cultivate medicinal plants. Many medicinal plants are root plants, the root growth environment is very critical, soilless cultivation can provide a good growth environment for medicinal plants, so the planting effect is very obvious.

4. It is used for fruit tree cultivation. The rootstock seedlings of fruit trees cultivated by soilless culture grow fast and the survival rate is high, while the fruit trees with rapid propagation by cutting take root quickly and have a high seedling rate.

5. It is used to raise seedlings without soil. The seedlings of soilless culture grow rapidly, the seedling age is short, the root system is well developed, strong and tidy, and the slow seedling time is short and easy to survive after planting. It can also avoid soil-borne diseases and insect pests caused by soil seedlings, and facilitate scientific and standardized management.

Advantages of soilless cultivation of vegetables

The main results are as follows: 1. Continuous cropping obstacles generally occur in the soil under protected cultivation, but there is no such obstacle in soilless cultivation and can be produced normally.

2. Soilless culture can avoid soil diseases and insect pests, the product is safer and the export potential is great. Of course, its benefit is much higher than that of protected cultivation.

Soilless cultivation is different in every place of identity, so we should ask more. Soilless cultivation has a lot of nutrients, so when making the formula, it must be very accurate, so as not to affect the growth of crops. There is a detailed introduction in the above, I hope it can be helpful to you.
