Grape water fertilizer integrated nutritional package fertilization method

Abstract

The invention provides a grape water fertilizer integrated nutritional package fertilization method, wherein the method comprises the following steps: S1, after fruit harvesting, applying a high-nitrogen and high-phosphorus fertilizer (19-45-6), an organic microbial agent and a soil conditioner; S2, before germination and flowering, applying a high-nitrogen and high-phosphorus fertilizer (19-45-6), a bacterial liquid, a foliar boron fertilizer and an organic carbon fertilizer; S3, in a young fruit expanding stage, applying a calcium magnesium fertilizer (13-0-0-17-6), a bacterial liquid and a foliar calcium fertilizer; and S4, in a fruit expanding color changing stage, applying a high potassium fertilizer (15-5-32), an organic carbon fertilizer and a foliar calcium fertilizer. Compared with the prior art, the method has the following beneficial effects that the fertilizer ratio is reasonable, the fertilization period is reasonable, fertilization is performed according to the grape nutrition requirement period, and the fertilizer utilization rate is effectively improved. The adopted fertigation is a precise fertilization method and is only applied to roots, fertilizer water infiltrates areas where root systems are located, and the fertilizer utilization rate is significantly increased; and compared with conventional fertilization methods, the method has the fertilizer amount saved more than or equal to 50% and the labor saved more than or equal to 60%.

Description

Technical field [0001] The invention relates to the field of grape planting, in particular to a method for fertilizing grapes with high-yield and quality-improving nutrition package. Background technique [0002] Grapes are rich in nutrients, and are loved by people all over the world with their delicious taste and special flavor. The main cultivars of table grapes in my country include European and Asian hybrids such as Kyoho, Fujiminori and Xiahei, and Eurasian species such as Red Globe, Rose Fragrant and Christen Seedless. The European and American hybrid grapes have darker leaves, early deciduous, and better cold and disease resistance than Eurasian species. [0003] The grapes grow vigorously, the results are large, and the demand for soil nutrients is also greater. Studies have shown that for every 1000 kg of Cabernet Sauvignon grapes, 5.95 kg of nitrogen (N) and phosphorus (P 2 O 5 )3.95kg, potassium (K 2 O) 7.68kg. For every 1000kg of red earth grapes, 5.4kg of nitrogen (...

AI Technical Summary

Problems solved by technology

[0004] In the traditional fertilization method for grapes, the ratio of fertilizer nutrients is unreasonable, and chemical fertilizers are often used, and organic fertilizers are used carelessly, resulting in acidification of the soil, green moss or red frost on the surface, and serious damage to the physical and chemical properties of the soil. Grape root growth is poor, root diseases are aggravated, fertilizer absorption and utilization rate is reduced, grape branches and leaves are weak, fruit acidity is high, color is poor, and commodity value is reduced

The patent document with the application number 201510432376.4 discloses a grape fertilization method, but the types of fertilizers used are still mainly chemical fertilizers. Long-term use will cause soil acidification, decrease in soil organic matter content, and decrease the ability of soil to retain water and fertilizer.

The application number is 201510255278.8, which discloses an integrated management method of grape water, fertilizer and medicine. The disadvantage of this method is that the mixing of fertilizer and medicine is easy to produce sediment and block the pipeline, and the second is that some components of fertilizer and pesticide will react and lose their application. It is effective, and the third is that the variety of fertilization is single, and the fertilizer is not applied according to the law of grape fertilizer requirement
