Cuttage raising method for olive seedlings on greenhouse hotbed

Abstract

A cuttage raising method for olive seedlings on a greenhouse hotbed includes: preparing a cuttage bed, acquiring scions, treating cuttings, performing cuttage, selecting cuttage time and performing post-cuttage management; setting the cuttage bed in a solar greenhouse; selecting an annual young tree as a female tree to acquire the scions, and selecting highly mature shoots without disease and insect damage as the cuttings; cutting each cutting into a cutting 10-12cm long with 4-6 segments, reserving 2-4 leaves at the top end of the cutting, smoothing the position, 0.5-1cm away from a bud, of the top end by cutting, and cutting the lower end of the cutting into an inclined horse-ear-shaped end; soaking the root of each cut cutting in 1000mg / kg-2000mg / kg indolebutyric acid solution at a 5cmdepth for one night; on the next day, dipping each cutting with mixture of indolebutyric acid and talcum powder before cuttage; reserving row spacing of the cuttings to be 5-6cm and plant spacing to be 3-4cm; keeping interior temperature of the solar greenhouse to be 18-20 DEG C, humidity to be 90%-95%, cuttage bed soil temperature to be 23-25 DEG C and water content to be 60%-70%; moving the seedlings, which root for 45-55 days, off the bed. By the method, the rooting rate of cuttage seedlings reaches more than 90%, calluses emerge 35-40 days after cuttage, and the seedlings can root in 45-55 days.

Description

technical field [0001] The invention belongs to a method for raising seedlings in the field of forestry, and in particular relates to a method for raising seedlings by cuttings in a warm room bed for olives. Background technique [0002] Olive (Olea europaea L.) is a precious woody oil tree species native to the Mediterranean region. Its main product, olive oil, is a well-known high-quality edible oil, known as the "Queen of Vegetable Oils". Although olive oil is a traditional product with a history of thousands of years, its production and sales have continued to boom in the past 20 years. This is due to the advancement of science and technology that has deepened people's understanding of olive products. In view of this, countries all over the world in the subtropical zone have shown strong interest in introducing olives. my country's large-scale introduction of olives began in 1964. The Bailongjiang River Valley in Longnan, Gansu Province is the best suitable area for gr...
