Nutritive cup provisional-planting substrate and provisional-planting method for tissue culture seedlings of downy grapes

Abstract

The invention relates to a nutritive cup provisional-planting substrate and a nutritive cup provisional-planting method for tissue culture seedlings of downy grapes. The method comprises the following steps of (1) preparing a downy grape provisional-planting substrate from 45 to 50 volume percent of red mud, 40 to 50 volume percent of peat and 1 to 5 volume percent of decayed farm manure, and placing the downy grape provisional-planting substrate into a non-woven nutritive cup; (2) selecting seedlings, namely selecting tissue culture seedlings with complete root systems and complete leaves; (3) performing provisional-planting, namely transferring the tissue culture seedlings in the step (2) into the non-woven nutritive cup in the step (1) for provisional-planting. According to the provisional-planting method for the tissue culture seedlings of the downy grapes, the root systems of the seedlings in the growth process of the downy grapes are complete, and a great number of lateral roots are formed, so that the survival rate of the seedlings is increased, and the seedlings can well grow in middle and later periods.

Description

technical field [0001] The invention relates to the seedling breeding technology of Vitis vinifera, in particular to the artificial planting technology of tissue-cultured seedlings of Vitis vinifera in nutrient cups. Background technique [0002] Vitis vinifera is one of the plant species in the plant kingdom. The plant belongs to the class of Angiospermae, Magnoliopsida, Rhamnales, and Vitaceae on the plant classification table. The fresh grape fruit contains a variety of vitamins, various amino acids, minerals and other nutrients, and is also rich in anthocyanidin diglucoside, superoxide dismutase (SOD) and resveratrol (RES), which have the functions of softening blood vessels, anti-aging, Anti-cancer effects. Mao grapes are characterized by high acidity, low sugar, thick skin, rich tannin, strong pigment, and unique aroma. It is a good raw material for brewing red wine. The wine brewed and processed by using grape berries as raw materials is favored by consumers for it...

AI Technical Summary

Problems solved by technology

At present, the commonly used nutrition cups are made of plastic materials. However, the air permeability, water melting and soil melting properties of plastic nutrition cups are not ideal. During the cultivation process of nutrition cups, substrate compaction often occurs, and the roots of grapes cannot penetrate the container wall and form rootlets. , thin roots, rotten roots and other problems, seriously reducing the survival rate of seedlings

At the same time, the resistance and growth rate of grape plants will be reduced, which will also have a major impact on the future growth of grape plants.

When transplanting, it is necessary to remove the plastic nutrition cup, which increases the workload and affects the efficiency

After the plastic nutrition cup is discarded, it is not easy to be decomposed, and it also pollutes the environment

In the choice of substrate, pure pond mud is often used. Due to excessive compaction, the survival rate of fake plants is low. The pure red mud as the substrate also has a similar phenomenon. With sand as the substrate, it is loose and breathable, and the survival rate is improved. However, the lack of nutrients in the substrate cannot Provide the nutrients needed for growth in time, and the substrate has weak water retention capacity, making the surviving seedlings grow slowly or grow poorly in the middle and late stages
