As it is known to all that grape is a kind of fruit which requires sufficient plant nutrients supply. Also, we need to focus on the apply period and concentration. More over, the application of secondary nutrients and micro-nutrients are important to the promising growth of grape.

Compare with other fruits, grape requires more plant nutrients especially for red grape. Due to its kind and character, it requiries 1.52 times of plant nutrients compared with apple and pear. 1.7 times of potassium compared with pear which is almost 2.25 times for apple. Satistically speaking, 100kg grapes need N:0.30kg; P:0.15kg; K:0.36kg. Therefore, it takes a lot of nutrients to make sure the harvest of grapes.

Different age of trees brought different needs of plant nutrients. Even though, the yound tree could absorb and transfer as the adult trees do. However, the young trees' life acitvity may be more on its own growth than nutrients absorption and transformation. Therefore, It gives us a requirement to choose plant nutrients. 

1.As for Young tree, N and P are essential. With suitable secondary and micro-nutrients, the growth should be alright with NPK:1:0.7~1.0:1.5.

2.As for adult tree, N is the key to successfully growth. Therefore, the growth may be accomplished with NPK:1:0.5~1.0:1.2. From germination stage to flower stage, the N's consuming could be half of a year. more times of N apply could promote growth. More over, it will bring a foundation to the high productivity.

After the flowering stage, Overdoes N could cause fruits dropping and flowers falling. At this stage, control the N is very important. Apply other kinds nutrients with suitable concentrations. In this period, we should try our best to get avoid with antagonistic joint action.

The grape takes a lot of actions and concentrations. However, We believe that quality is forged by professional attitudes.
