Embodiment 1

[0038] Preparation of walnut green husk concentrated juice and chelate

[0039] 1) Preparation of concentrated walnut green peel juice by physical method

[0040] After separating the green skins, the fresh green skins were squeezed with a high-speed juicer to obtain walnut green skin juice, and the calculated juice yield was 54.2%.

[0041] Table 1 data shows, with 10kg fresh green walnut as basis measurement, after its green peel is peeled off, obtain fresh walnut green peel 6.89kg, the walnut green peel yield rate of fresh green walnut is 68.90%, obtain 5.42kg green peel juice and 1.01kg after squeezing Green bark dregs, yields are 54.2% and 10.10% respectively, green bark juice after filtering is 4.16kg, and its yield rate is 41.60%. It can be seen that 10kg of fresh walnuts can be squeezed to obtain 41.6% filtered green skin juice and 10.10% green skin residue. There is a higher yield of juice.

[0042] Table 1 Yield of green skin, green skin juice and green skin dregs...

Embodiment 2

[0056] A nutritional bacteriostatic agent for grapes, comprising the following raw materials: 16 L of concentrated walnut green peel juice, 1 L of calcium glycinate chelating solution, 1 L of copper glycinate chelating solution, 24 g of boric acid, and 1.2 g of zinc sulfate.

[0057] The preparation method of above-mentioned grape-specific nutrient bacteriostatic agent comprises the following steps:

[0058] (1) Preparation of concentrated walnut green peel juice: crush fresh green peel, squeeze, and filter to obtain walnut green peel juice at a temperature of 70-80°C, vacuum concentrate to 1 / 3 of the original weight, and obtain concentrated walnut green peel juice;

[0059] (2) Preparation of calcium glycinate chelating solution: temperature 60°C, time 1.5h, material ratio n(glycine):n(CaCl 2 )=1.5:1, add water to adjust CaCl 2 Concentration 1L / mol;

Abstract

The invention belongs to the technical field of grape planting and specifically relates to a nutritional bacteriostatic agent special for grapes, a preparation method and an application thereof. The nutritional bacteriostatic agent special for grapes comprises the following raw materials: 8-16L walnut green seedcase concentrated juice, 1L calcium glycinate chelating liquid, 1L cupric glycinate chelating liquid, 24g-36g boric acid and 1.2g-2.4g zinc sulfate. The preparation method for the walnut green seedcase concentrated juice comprises the following steps: crushing, squeezing and filtering fresh green seedcase, thereby acquiring the walnut green seedcase juice, and then performing vacuum concentration, thereby acquiring the walnut green seedcase concentrated juice. The nutritional bacteriostatic agent is a botanical fungicide and is capable of sterilizing while supplementing the nutrition required by the grapes, boosting the growth of grapes and preventing and controlling insects anddiseases. The invention also provides the preparation method for the nutritional bacteriostatic agent and a related application effect.

Description

technical field [0001] The invention belongs to the technical field of grape planting, and in particular relates to a special nutritional bacteriostatic agent for grapes and a preparation method and application thereof. Background technique [0002] Grape occupies an important position in the world's fruit production. The total area of ​​grape cultivation in China reaches 4.119 million hm2, and the grape output is 5.964 million tons. Grape diseases and insect pests have a great impact on the growth and development, yield and quality of grape plants. Especially in rainy areas and in rainy years, diseases are often rampant and popular, which brings great losses to grape production. There are many kinds of grape diseases and insect pests, and the occurrence rules are complicated, which brings great difficulties to the control. [0003] As one of the four major dry fruits in the world, walnut is a kind of woody grain and oil plant with high comprehensive development and utiliz...
