A large amount of applied fertilizer is applied to the greenhouse of the grape in the low temperature season. The temperature in this period is low and does not meet the needs of normal grape growth. The activity of active bacteria in the soil is low, and the roots of the grapes are underdeveloped, which cause poor absorption of fertilizer and poor effect of fertilization. Therefore, improving the vigor of grape roots and increasing the growth of grape roots is a necessary means of applying fertilizer.
A variety of fertilizers are compounded and applied. Since one household is fertilized separately, the soil and fertilizer conditions vary greatly, and it is not easy to apply a certain fertilizer uniformly. Therefore, it is recommended that you use a variety of fertilizers to mix and apply to solve the grape lack of certain nutrients, increase fertilizer performance and actual results.
Master the nutrient characteristics of the grapes, such as the demand for various nutrients in each fertilization period; we need to rush more nutrients needed during this period. The right medicine, the effect of doing more with less, and improving the efficiency of fertilizer.
Scientific rotation: a small amount of fertilizer applied. In particular, grape greenhouses, because they mainly rely on watering, so generally watering, so that a small amount of fertilizer can be applied, such as can be applied once every important fertilization period. And in each rush, a reasonable combination of a large number of elements, trace elements and grape root growth promoter.
Note that several fertilizers cannot be mixed, otherwise the effect will be reduced or no effect. For example, ammonium bicarbonate cannot be mixed with strong acid fertilizer, amino acid fertilizer can not be mixed with humic acid fertilizer, and phosphoric acid fertilizer should be added with zinc, manganese, iron, copper and other fertilizers to add chelating agent.
