It is also important to nurture the soil, how to make the soil more vigorous?

High-quality seedlings can only grow in high-quality soil, and how much fertility is there on the land where the seedlings are planted?At present, many nursery operators have not applied farm fertilizer for many years, and the land on which we grow seedlings is getting thinner and thinner.

The main reasons for not using farmyard manure are as follows:

First, the cost of applying farmhouse fertilizer is high, and the effect is slow. The role of a ton of cow and horse manure is not as good as the role of a hundred catties of chemical fertilizer, not to mention that there are fewer and fewer large livestock in rural areas, and some people who specialize in livestock and poultry breeding generally have professional partners to process animal manure for vegetable or flower breeding. In addition, because more manpower is required to apply animal manure, ploughing is required after application, and the labor cost is high.

Second, some seedling operators are greedy and greedy in order to make more money. I can't wait for the seedlings to grow up to 10 centimeters in a year, so that instead of applying the slow effect of farm fertilizer, and blindly apply the fast effect of chemical fertilizer, so that a vicious circle is formed, the seedlings grow faster and faster, the ground is thinner and thinner, and the fertilizer is used more and more. What is the result of this?

That is, due to the long-term application of chemical fertilizers, the soil has become compacted and lacks vitality, although the trees are growing well, the internodes have become longer, the degree of lignification has been lowered, the cold resistance and wind resistance have weakened, the trees are more susceptible to diseases and pests, and some trees that were originally very solid have also become non-solid.

In order to develop the seedling industry healthily, it is first necessary to be able to produce high-quality seedlings, and high-quality seedlings can only grow in high-quality soil. Therefore, we must look at the soil problem of the nursery from a strategic perspective!As the old saying goes".Soil can make goldBut by "soil" we mean fertile soil, not poor soil.

Hence,We must learn to raise the soil while raising seedlingsAlthough the effect is slow, it has stamina, which is a good thing for the present and for the future!

So how do we need to raise our land?

First, it is necessary to rationally apply farm fertilizer and chemical fertilizer, and the two should be reasonably matched. If the combination is appropriate, it complements each other, which is not only conducive to the growth of plants, but also can make the soil more and more fertilized.

The second is to allow the land to "rest" appropriately. Land, like people, also needs rest, and after a few years of cultivation, the soil can be left idle for one or two seasons, which can restore the fertility of the soil and effectively reduce the occurrence of pests and diseases.

The third is to adopt the method of seedling rotation. This also allows the soil to maintain a higher fertility and the land that has undergone crop rotation is more vigorous and produces better seedlings.

Fourth, the use of microbial bacteria to fertilize the garden. Improve soil structure, improve soil fertility, and cultivate strong seedlings.

For the current nursery land is getting thinner and thinner, seedling breeders should pay attention to it, and the local ** and related organizations should also attach great importance to it, and actively guide and standardize, so as to promote the healthy development of the seedling industry.

In addition to not abusing chemical fertilizers, pesticides should also not be abused, which is easy to pollute the environment.

In sunny weather, the land is turned over to drive away bacteria, germs and insect pests, enhance the soil permeability, mix soil with farmer's organic fertilizer or plant ash to ferment the soil to make the soil rich in humus, supplement sufficient water to reduce the harm of high salinity of the soil, and let the soil rest for a period of time, so as to make the soil more vigorous.

1. Ploughing the soil with a small gardening fork helps to mix all the components of the soil, but be careful not to damage the roots, stems and leaves of the plant.

2. Pay attention to the depth of the loose soil, the effect of the loose soil is not good, and the deep soil is easy to hurt the plant roots, so the depth of the loose soil is subject to the roots, and some surface roots can be appropriately cut off to help new roots.

3. Pay attention to the frequency of loosening the soil, generally speaking, it is definitely good to loosen the soil, and we can loosen the soil when we see the branches to the soil compaction. But if you accidentally hurt the roots of the plant by loosening the soil, then don't loosen the soil in the near future, and reduce the frequency.
