Embodiment 1

[0033] A soilless culture medium for grapes. The soilless culture medium for grapes is made of the following components: 70 parts by dry weight of crushed grape branches, 20 parts by dry weight of organic fertilizer, 1 part of calcium magnesium phosphate fertilizer and 0.1 part of compound fertilizer.

[0034] Wherein, the crushed grape branch is a granular material with a particle diameter of 2-5 mm.

[0035] Organic fertilizer: Commercial organic fertilizer should be selected from the excrement of pigeons, sheep, and rabbits that has been processed harmlessly in a factory. Its standards should meet the following aspects:

[0036] 1) Technical indicators

[0037] Organic matter mass fraction (based on drying basis) ≥ 45%

[0038] The mass fraction of total nutrients (nitrogen + phosphorus pentoxide + potassium oxide) (calculated on an oven-dried basis) ≥ 6.0%

[0039] Moisture (fresh sample) mass fraction ≤ 25%

[0040] pH (PH)6.5-7.5

[0041] 2) Metal indicators (unit: m...

Embodiment 2

[0058] Basically the same as Example 1, the difference is: 75 parts in dry weight of grape branch pulverization, 20 parts in dry weight of organic fertilizer, 1.5 parts in calcium magnesium phosphate fertilizer, and 0.15 part in compound fertilizer.

Embodiment 3

[0060] Basically the same as Example 1, the difference is: 73 parts in dry weight of crushed grape branches, 23 parts in dry weight of organic fertilizer, 1.3 parts in calcium magnesium phosphate fertilizer, and 0.13 parts in compound fertilizer.

Abstract

The invention discloses a soilless culture medium for grape, made from crushed grape shoots, organic fertilizers, calcium-magnesium-phosphate fertilizer, and a compound fertilizer. The invention also discloses a preparation method and application of the soilless culture medium for grape. Through the reasonable medium ratio, the problem that grape not dependent on soil is difficult to culture is solved, and land resource utilization at difficult sites (saline-alkaline soil, sandy soil, Gobi Desert, islands and the like); waste shoots from winter pruning of grape are used as a medium, straw waste is fully and cyclically utilized, all minerals and metal nutrients required for the growth of grape are met, materials are easy to obtain, and the cost is lowered; through the use of the complex medium, the problem that a single medium is not good for the growth and development of grape is solved; under single matching and fertility replenishing, it is possible to use for years, and the problems of short service life of a medium and frequent replacement of the medium are solved; the medium has balanced nutrition, and mineral nutrients and metal elements necessary to the growth of grape are met.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a soilless cultivation substrate for grapes, a preparation method and application thereof. Background technique [0002] Grapes are mainly cultivated in soil, and soil management requires a lot of labor and root system management is difficult. The application of substrate as a medium for soilless cultivation is still in the exploratory stage. Due to the requirements of grape growth on soil, its cultivation in areas without soil (soil scarcity) and soil unsuitable for grape growth is limited, such as deserts, neighbors, saline-alkali lands, and islands. The existing matrix mainly comes from peat, vermiculite, perlite, coconut peat, etc. produced in industrialized factories, and the cost is high. Contents of the invention [0003] Purpose of the invention: the first technical problem to be solved by the present invention is to provide a soilless cultivation subst...
