What are the advantages of soilless cultivation of watermelon in gardening? Compared with 2 points, it costs less and grows well
Some farmers said that planting watermelon in the greenhouse caused serious soil salinization, poor growth and low yield due to unreasonable Fertilization Formula. If you plant in another greenhouse, and you have to reinvest, the original greenhouse will be wasted. Seeing that soilless cultivation is a new method, I wonder if watermelon can be planted? What are the advantages?
Many farmers missed the high yield because of the salinization of greenhouse soil, and tried to switch to soilless cultivation mode. However, many farmers are unfamiliar with soilless cultivation and do not know how to get started. The gift watermelon planted in our greenhouse adopts matrix cultivation method, which has obvious advantages compared with soil cultivation.
- Low cost
In the impression of many farmers, soilless cultivation is a large investment and high cost. Now with the popularization of new technology, the cost of soilless cultivation is getting lower and lower, which is suitable for ordinary farmers. Using planting bags as planting slots is cheap and durable. Using earthworm dung, cow dung and rice husk as the cultivation substrate saves a lot of money than using coconut bran and peat soil. With the change of infrastructure, the whole planting cost has also been reduced.
The old greenhouse can still be used. It can be directly placed in planting bags. One or two seedlings can be planted in one bag. Cow dung or earthworm dung can be used as the substrate, but cow dung needs to be fermented in advance. There is a small amount of nutrition in the substrate. After watermelon is planted and before the slow seedling, no fertilizer is needed when watering, so as to reduce the damage to the root system.
- Good growth
Some farmers say that the soil contains more nutrients and the substrate contains less nutrients. Is it good for watermelon growth to replace the soil with substrate? The permeability of substrate is better than that of soil, which is the advantage of soilless culture. When we plant watermelon with earthworm dung or cow dung, the permeability is good, which is conducive to the growth of roots. When the roots are strong, the growth is naturally not bad.
For example, after the watermelon seedlings are planted, they should be watered thoroughly and evenly. After soil planting and watering, the air will be discharged, and there will be less oxygen in contact with the root system for a long time, which is not conducive to rooting. After watering the substrate, the air permeability is good, and the air can come in in a short time, which is conducive to slow seedlings. Therefore, the advantages of substrate cultivation can be seen from the early growth of watermelon.
The permeability of the matrix is good, on the contrary, the water retention will be weak. Some farmers worry that frequent watering in the greenhouse will increase the air humidity, which will aggravate the occurrence of diseases? For example, the common anthracnose of watermelon is difficult to control when the humidity in the shed is high. In matrix cultivation, although the watering times are more than that of soil, the amount of watering each time is small, and the waste of water and fertilizer is less. Basically, the medicine is applied once in the early stage to prevent the occurrence of diseases in a large area. After the soil is planted and watered, the water between the ridges will overflow, and the humidity in the shed is high, causing serious diseases.
Changing the planting mode of watermelon, not only grows well, but also the cost is very low. But before planting, we should not be blind. We must learn first, master water and fertilizer and field management, and then we can plant well!
