Seeing this topic, perhaps a vegetable farmer will ask, is it not a good thing to have enough base fertilizer? In fact, sufficient base fertilizer is indeed a guarantee for the high quality and high yield of vegetables. Applying basic fertilizer is also a basic measure that we have always advocated. However, then again, there is less demand for nutrients during the seedling period. During this period, the nutritional status of the soil is undoubtedly an excess. In the case of excess nutrients, the growth of vegetables will show abnormalities, mainly in the leggy, flowering fruit set rate is low. It is understood that, at present, 80% of the greenhouse vegetable has various degrees of leggy in the early stage of planting. One of the main reasons is the excess nutrients. Only three or five times of regulation by vegetable farmers can make the vegetables grow normally. Therefore, there is not much benefit for the seedling vegetables in terms of sufficient base fertilizer.
So, should we reduce the amount of base fertilizer? That is certainly not the case, because the nutrition of the base fertilizer is prepared for the whole growing period of the vegetables. If only taking into account the seedling period of the vegetables, reducing the amount of the base fertilizer will certainly affect the overall yield and benefit of the vegetables. So, how can we solve this problem? The author believes that we should pay attention to the following two points:
First, do not carry fat in the planting hole. When the vegetables are planted, the vegetable growers often have the habit of planting fertilizer in the planting hole. The purpose of doing this is nothing more than the fear of lack of fertilizer in the vegetable seedling stage. In fact, the basic nutrients provided by the base fertilizer are very adequate. If the fertilization is carried out in the planting hole, it will undoubtedly exacerbate the growth of the vegetables. Of course, in order to promote root disease prevention, biological bacterial fertilizers can be used in planting holes, and some fertilizers containing large amounts of nutrient elements should not be used again.
The second is to minimize the number of watering. As we all know, the effectiveness of the base fertilizer effect is greatly affected by the soil moisture, the soil moisture is suitable, and the fertilizer effect in the base fertilizer can be fully exerted, whereas the fertilizer effect is exerted slowly. Therefore, in order to avoid vegetable seedlings due to sufficient base fertilizer and length, it is possible to minimize the number of watering at the seedling stage, and in the case of slower base fertilizer fertility, the vegetables will not be easy to grow again.
