The first is heavy organic fertilizer light fertilizer. “Ample amount of organic manure is an important guarantee for the quality of the grapes. Organic fertilizers are rich in trace elements, but also make the soil loose and breathable, and there are many benefits.†Zhu Lijun said that when building a vineyard, organic fertilizer should be applied to every acre of land. 3 tons of fertilizer, after the annual application of 1.5 tons of land per acre. In the middle and late stages of grape growth, topdressing chemical fertilizers are used, with 100 yuan of compound fertilizer or 30-40 kg of water-soluble fertilizer.
In the second section, the grapes are planted and planted in large quantities, yields are not reduced, and the quality can be improved. Grapes like light and are extremely responsive to soil and fertilizer. Most of the traditional grape planting methods adopt dense planting methods, and about 200 plants are planted per acre. The management is difficult, time-consuming and labor-intensive, and the input cost is high. At the beginning, Zhu Lijun’s vineyard was planted with 220 strains per acre, which was subsequently reduced year by year, from 60 plants per acre to 20 plants and then to 10 plants per acre. At the same time, he artificially adjusted the branches of the vines into a “king†shape structure, with good lighting and ventilation, and also facilitated mechanized management. "The sparse planting of grapes not only reduces the investment in the seedlings for the establishment of the park, but also greatly reduces the difficulty of management, saves labor, saves labor, saves fertilizer, and is conducive to ventilation and light transmission. The quality of the grapes is greatly improved." Zhu Lijun said that at present, his vineyard Some varieties only have 10 plants per acre, each with a yield of 300 to 450 catties and about 4,000 pounds per acre. The output is not very high, but because the quality is good, the price is selling high.
The last one, how to plant high-quality grapes? Zhu Lijun introduced: "Need to plant green. Without hormones, less pesticides. Without any plant growth regulators, use biological pesticides to prevent pests before flowering, and stop using herbs after flowering."
