Master 3 skills, vegetables planted in growth bags, the same high yield, and very simple
Recently, many friends asked that it is very popular to plant vegetables in bags. It seems very convenient. I also began to plant in this way. I placed the bags and filled them with substrate, and then began to plant seedlings. But in the field management, there are many problems and the effect is not ideal. What is the reason?
Planting vegetables in planting bags is a kind of soilless cultivation method that saves money. For farmers who plant for the first time, there will be various problems without learning. Before planting seedlings, we should pay attention to several aspects, so as to improve the survival rate, facilitate the later water and fertilizer management and save labor.
- Selection of planting bags
What kind of planting bags to use should be considered comprehensively. Some farmers use non-woven cloth bags, some farmers use plastic planting bags, and some farmers use nutrition pots for seedling cultivation. The advantage of non-woven bag is good air permeability. If the water holding capacity of the substrate is poor, it will soon dry after watering. It may need to be watered several times a day to maintain humidity. Both sides of the nutrition bowl are black, with strong heat absorption. If the temperature is too high during planting in spring and autumn, the root will be damaged.
The upper opening of the black-and-white plastic planting bag can meet the oxygen demand of the root system, and has a certain water holding capacity after watering. It is very suitable for the planting of tomatoes, cucumbers and other vegetables. The white outside can reflect the light and maintain the temperature. The black side can prevent some light from damaging the exposed roots. Therefore, if the substrate cultivation method is adopted, it is best to select the planting bag.
- Watering before or after seedling
Some farmers directly plant seedlings after installing the substrate, and then water the seedlings. If the seedlings are planted in this way, they may dry up and die, because it is difficult to quickly water the substrate after planting the seedlings, and the root system cannot absorb water for a period of time, so the seedlings will have problems. The correct method should be drip irrigation one day before planting seedlings, fully moisten the substrate, and then plant seedlings. The dead seedling rate is low.
- Plant several seedlings in a bag
The height of the planting bag is generally 20 cm. The roots of tomatoes and cucumbers we plant are 78 cm. When they are filled with substrate, they can meet the growth of vegetables. When tomato, cucumber, pepper and other vegetables are planted in the soil, attention should be paid to the spacing between plants and rows. When soilless cultivation is adopted, it is easy to plant seedlings without drilling holes. Planting in a planting bag. Generally, two seedlings can be planted in one bag. According to the direction of drip irrigation belt, one seedling can be planted at one side, and one dead seedling can be planted in one planting bag for strawberry. The space between bags shall be 5cm, and there shall be a suitable width between rows to facilitate field management and picking.
When we use planting bags to plant vegetables, we should pay attention to the above three problems, so as to avoid detours, improve the survival rate of seedlings, and save money and labor fees.
