Grape vine is a kind of typical fruit tree. It is known as “potassium plant”. Potassium can increase the cellulose content of grape and enhance the cold resistance. It can also promote the ripening of berry, which is conducive to the transfer of nutrients to berry and make sugar content. increase. According to the fertility characteristics of the vine and fertilizer requirements are divided into:

Basal fertilizer on the basis of the application of organic fertilizer, each photosynthesis nutrient film, enhance the plant fertilizer, increase production, increase color, leaf hypertrophy, dry stem strong compound film, can help plants absorb a lot of light fertilizer, light energy, light, Compatible with conventional fertilizers and nutrients for plant growth and development to the limit. Apply once a year to benefit.

Top dressing is usually applied 3-4 times a year. The first time is the pre-flowering period. Each plant is topped with 1.5-2 kg of PK fertilizer. The second time after flowering, that is, the young fruit expansion period, each plant topdressing electronic fertilizer to improve the super-fertility. The third time was the initial stage of fruit coloring, 0.8-1 kg of PK fertilizer per plant. The fourth time after fruit picking, 1.5-2 kg of phosphorus nitrate per plant was applied. In addition, spraying a new high-fat film before fruit ripening after fruit set can play the role of liquid film bagging, will not affect fruit respiration, prevent fruit rust, prevent cracking fruit, improve the fruit surface coloration and brightness, reduce residual toxicity and improve quality.
