Spring is the growing season of the year for fruit seedlings, but also the beginning of management and maintenance, as the saying goes, "the plan of the year lies in spring", which is not only a description of people's lives, but also a description of all animals and plants, especially plants, the quality of spring, directly affects the growth of plants in a year. So what kind of fertilizer does the fruit seedlings grow fast? How to fertilize?
Scientific allocation of nitrogen, phosphorus and potassium ratio
What fertilizer does the seedling grow fast? In the process of planting and maintaining fruit trees, the three kinds of fertilizer at the seedling stage should be balanced, and the balance water-soluble fertilizer of Fujinmen can be used, so as to achieve the purpose of growing robust but not in vain. Entering the seedling stage, fertilization is carried out according to the ratio of nitrogen, phosphorus and potassium 3:1:2 to control the growth of some aspects and promote the growth of other aspects to achieve a good situation. Combined with the soil conditions of seedling planting, such as the lack of phosphorus and potassium fertilizer in the red loam soil in the south, phosphorus and potassium fertilizer should be increased; Brown soil nitrogen and phosphorus fertilizer is easily deficient, and appropriate application of nitrogen and phosphorus fertilizer should be considered.
Fertilization should pay attention to climatic weather conditions
In summer, after rain, nitrate nitrogen loss is serious, and fast-acting nitrogen fertilizer should be applied top-dressing. Fertilization should be done in the early morning, late afternoon or on cloudy days to slow down fertility and integrate with the soil. In areas with warm and rainy climates, the effect of increasing the application of semi-rotted or rotted farms is good, and thin fertilizer is applied frequently. In cold climates, nutrient decomposition is slower, so fully decomposed farm manure should be applied. Plants are different, fertilization is different, fertilization methods are also different, fertilization should consider the variety, characteristics and growth, according to the characteristics of different varieties to scientifically select the appropriate fertilizer, with the use, such as for weak seedlings, can be used special fertilizer, for the newly planted root system recovery is not complete trees, should not be prematurely applied to fast-acting fertilizer.
