Nowadays, most people use the greenhouse cultivation mode. In addition to the temperature control, it is also important to control the fertilizer in the greenhouse. What are the points to pay attention to when using fertilizer in the greenhouse?
1. Use the greenhouse for many years
If the greenhouse has been used for many years and often uses fertilizer, then in the soil, a lot of fertilizer will be deposited, because not all of the fertilizer will be absorbed by the crop, many elements will accumulate in the soil, so use fertilizer again. If you want to pay more attention. Do not use too much, but instead use more fertilizer, so that plants can better absorb the fertilizer remaining in the soil, and reduce the burden on the soil.
2. Newly built greenhouse
Newly built greenhouses may not be very close to soil nutrition. If you want to grow crops, you need to use a lot of fertilizer. For example, if you use base fertilizer, you should use some manure fertilizer. This is very good. The elements inside are relatively well balanced, but this must be completely decomposed before it can be used. Otherwise, it will affect the crop.
In addition to the bacterial fertilizer, this is also very necessary, so that these manure can be better absorbed. In addition to these, there are some chemical elements. Many elements are more important, and it is easy to ignore some small elements. In fact, they are also very important.
3. Look at soil fertilization
Different greenhouses have different soils. If the soil is different, the absorption and preservation of fertilizers will be different. Therefore, it is very important to use fertilizer according to different soils. For example, if the sand is used, the ability to maintain fertilizer will be poor. At this time, it is necessary to use some things to adjust the land. If the soil is sticky, although it is strong, it is not very transparent. You can use some farmyard fertilizer appropriately.
