The best time and method for raising grape seedlings by cuttings

Grape reproduction methods are mainly divided into two categories: sexual reproduction and asexual reproduction. Sexual reproduction is cultivation through grape seeds , but this method has certain limitations and problems, so it is rarely used in actual production. In contrast, asexual reproduction is widely used due to its stability and efficiency, and includes techniques such as cuttings, layering and grafting. Among these asexual propagation methods, cutting seedling cultivation has become the most commonly used seedling cultivation method due to its simple operation and high survival rate. Let's learn about the best time and method for growing grape seedlings through cuttings.

1. Best time

Grape cuttings are mainly divided into two methods: hard branch cuttings and soft branch cuttings. Their best times are slightly different:

Hardbranch cuttings: Usually carried out in March and April in spring, because the temperature gradually warms up at this time, which is conducive to the rooting and growth of the cuttings.

Softwood cuttings: It is suitable to be carried out from June to August in summer. The high temperature and humidity conditions at this time help to increase the rooting rate of softwood cuttings.

2. Cutting method

Cutting preparation: Choose healthy, disease-free and insect-free grape branches as cuttings. The length of the cuttings for hardwood cuttings is usually 15-20 cm, with 2-3 full buds; for softwood cuttings, semi-lignified new shoots are selected.

Hormone treatment: In order to increase the rooting rate, rooting powder can be used to treat the base of the cuttings. Soak the base 1-2 cm of the cuttings in 50-100 mg/kg ABT rooting powder solution for about 1 hour.

Cuttings: On the prepared seedbed, insert the cuttings into the soil at appropriate intervals (usually 12-15 cm), with the depth being enough to expose a bud. After planting, compact the soil to ensure that the cuttings are in close contact with the soil.

Management after cutting: Water thoroughly immediately after cutting, and keep the soil moist to prevent the cuttings from drying out. A shade net can be built above the seedbed to reduce direct sunlight, lower the temperature, and prevent the cuttings from transpiration too quickly. Spray water regularly to keep moisture, and pay attention to preventing and controlling diseases and pests.

Transplanting: When the cuttings have taken root and grown new leaves, they can be transplanted. Be careful when transplanting to avoid damaging new roots.

In short, I hope everyone can follow the above steps to carry out grape cuttings and seedling cultivation at the best time and with appropriate methods in order to obtain healthy grape seedlings .
