The purpose of fertilization is to meet the needs of vegetables and to increase the output of vegetables. However, the types and quantities of nutrients absorbed by vegetables in different growth stages are also different. Therefore, the fertilization focus is different in different growth stages.
The results are the key period for fertilization by vegetable farmers, but the focus of fertilization before and after the results is different. As before the results, the focus of greenhouse vegetable management is to promote roots and strong trees, laying a good foundation for the continuous results of the later vegetables. In the result period, it is to quickly expand the fruit and increase the yield.
According to the above characteristics, the vegetable should be washed as follows before the flowering result:
Before the results: can be used to apply roots, the amount of mu is about 10 kg, roots are promoted by roots; biological fertilizer can also be used for rushing, such as Dayuan new fast gunners, etc., 40-80 kg of mu. It can also be used for augmentation of 10 kg of balanced growth type acre per acre to ensure the growth balance between roots and stems and leaves.
Result period: The demand for nutrients in vegetables is increased, especially the demand for potassium is greatly increased. In order to promote fruit enlargement, high potassium fertilizer is applied to ensure the balance between vegetative growth and reproductive growth. Generally, it can be applied to 10-15 kg of high-potassium fertilizer of Fangrun 20-10-30.
The result is late: the result is that the root function declines and the nutrient absorption capacity decreases in the late stage. In order to coordinate the vegetative growth and reproductive growth, according to the characteristics of vegetables requiring fertilizer, fertilizers for promoting root growth should also be added, such as Jiajia and Dayuan new fast gunners. The effect is good.
