How can farmers water soilless seedlings? Pay attention to 2 points, slow seedlings, fast growth in gardening
Now many friends began to try to do soilless cultivation, but because of the lack of experience, there are many problems, in fact, after mastering the principle, it is very easy to solve!
Recently, some farmers said that they put a few planting bags in the greenhouse, try soilless cultivation, and see how it grows. There are tomatoes, pumpkins, peppers, but after planting the seedlings, after watering the colonization water, it is found that the seedlings are seriously wilted and the survival rate is low.
This farmer planted dozens of trees in the greenhouse, although the greenhouse has been idle, the soil compaction is more serious, but it does not affect the soilless cultivation. Dozens of planting bags were placed in the greenhouse, which were filled with fermented cow dung, and then began to plant seedlings, watering, and found dead trees during the seedlings. Many friends who have just started planting have encountered such problems, mainly because the colonization water is not watered well.
Because the substrate in soilless cultivation is better, the water retention will be a little worse, and it is easy to seep out after watering. If the colonization water is not watered thoroughly after planting, the substrate is unevenly dry and wet, and some roots cannot absorb water, then there will be a situation of wilting and dead seedlings. Therefore, if soilless cultivation wants to improve the survival rate, the colonization water must be watered thoroughly.
If the colonization water wants to be watered thoroughly and evenly, two questions must be considered: First, before planting seedlings, do you need to water first? Second, how to use drip irrigation belts?
1, many friends colonization, first plant seedlings, and then water the planting water. However, because of the water permeability of the substrate, it is found that it is difficult to water evenly, and some roots cannot absorb water, and they will wilt after a long drought.
The correct method is: for example, using cow dung as a cultivation substrate, after bagging, it should be drip irrigated with water to fully moisten the substrate. It is best to do it a day in advance, once every four or five hours, two or three times in a row. This not only wets the substrate, but also flushes away some salt.
After planting the seedlings, it is easy to water them well. After watering, it is conducive to rapidly slowing down the seedlings and improving the survival rate, generally four or five days, you can slow down the end of the seedlings. During the slow seedling stage, only water is watered with water and no fertilizer is added to prevent damage to the root system. This is a difference between watering before planting seedlings and watering after planting seedlings, and farmers should pay attention to them.
2, some planting bags, planted two seedlings or four seedlings, in order to increase the watering area, watering more evenly, you can lay two drip irrigation belts. The water outlet of the drip irrigation belt is in the position of the two seedlings, so that the watering is more uniform, which is conducive to the absorption of the root system and promotes the slow seedlings.
Therefore, in the process of soilless cultivation, in order to improve the survival rate of seedlings, the planting water must be watered thoroughly when planting seedlings. Whether it is a large area of planting or planting a few trees in a vegetable garden, this method is very suitable.
