In the midsummer of July, the sun is scorching. Right now, it is the grape - harvesting season. Entering Gong'an County, which has the reputation of "the No.1 Grape County in the Jiangnan Region", grape vines are everywhere, with plump and translucent grape clusters. Well, let's follow the footsteps of the editor and go to Sanhe Village, Buhe Town, to see how the grapes in Zhou Changfeng's demonstration field have made a comeback and thrived after applying Yishizhuang organic fertilizer.
Boss Zhou Changfeng in Sanhe Village, Buhe Town, Gong'an County, is a large - scale grower with many years of experience in grape cultivation. Over the years, he has been using the experience - based fertilization method, that is, applying base fertilizer once and top - dressing twice. The total amount of 45% balanced compound fertilizer applied each year is 80 - 120 kg. Although he has started to pay attention to the application of organic matter in recent years, he mostly uses chicken manure, with an application amount of about 700 - 1000 kg. Long - term application has led to serious soil salinization in the vineyard, and the quality cannot be guaranteed.
When Boss Zhou was distressed, he accidentally learned that Yishizhuang organic fertilizer had a good effect on grape cultivation, so he had the idea of changing the fertilization method. Introduced by someone, in December last year, agrochemical experts from Yishizhuang went to his vineyard and detected that the soil pH value reached 8.63, which is medium - strong alkaline and contrary to the grape - growing environment.
At Boss Zhou's request, the agrochemical experts formulated a fertilization plan based on the soil conditions and the fertilizer requirements of Fujiminori grapes: 800 kg/mu of Yishizhuang organic fertilizer (N + P₂O₅+K₂O≥6%, organic matter≥45%) + 60 - 100 kg/mu of his commonly used 45% balanced compound fertilizer. The amount of compound fertilizer was reduced by 20% compared with conventional fertilization. The purpose was to reduce the amount of inorganic fertilizer and use high - quality organic fertilizer to replace chicken manure, so as to improve the soil and enhance the quality.
Currently, during the grape - ripening period, the agrochemical service personnel have conducted soil tests and quality inspections on Boss Zhou's vineyard.
4. The tree vigor is good, the leaves are dark green, the fertilizer effect is long - lasting, and there is no fertilizer - deficiency situation in the leaves even when the grapes are bearing fruit, which forms a strong contrast with conventional fertilization.

Through this experiment, the application of Yishizhuang pure plant - source organic fertilizer has significantly improved the tree vigor of grapevines, improved problems such as soil compaction and salinization, and enhanced the fruit quality. Boss Zhou said that it not only increased certain economic benefits but also laid a good foundation for the future development of grapes.
