Apple nontoxic dwarfed self-rooted rootstock M9-T337 rapid propagation method

Abstract

The invention belongs to the field of agricultural technology, and in particular relates to a rapid breeding method for apple non-toxic dwarf self-root stock M9‑T337 stock. The method comprises the following concrete steps: construction of stock parent gardens; construction of breeding gardens; construction of demonstration gardens, and construction of modern apple cultivation demonstration gardens according to the standards of "four reforms, three transformations and three festivals". The invention adopts the layering technology of the same year of planting, shortens the time for seedlings to emerge from the nursery, and improves the breeding efficiency of seedlings. Adopt the method of flat stubble when the new seedling grows to 20cm, promote it to increase 2-5 new shoots, and when most of the new shoots grow to 30cm, 40cm, and 50cm on the seedling stem, press the decomposed sawdust 10cm / time in 3 times, and then Cultivate 5cm of soil to promote new roots of new stock seedlings. Compared with the foreign method of mixing soil with sawdust, it saves labor, time and effort. At the same time, this breeding method shortened the breeding time of non-toxic M9-T337 apple dwarf self-root stock by 50%, and increased the number of reproduction by more than 2 times.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a rapid breeding method for apple non-toxic dwarf self-root stock M9-T337 stock. Background technique [0002] Intensive cultivation of apples with short stock is not only the trend and direction of the development of the world's apple industry, but also the only way for the development of my country's modern apple industry. Dwarf rootstock is the most important way to realize apple dwarf stock cultivation. At present, the newly-built orchards in major apple producing countries in the world basically adopt the intensive cultivation of short stock, which has accounted for more than 90% of the total apple cultivation area. However, more than 90% of the existing apple orchards in my country are arbor fruit trees. The orchards are closed, poorly illuminated, and labor-intensive to manage. It is a traditional cultivation mode with high consumption and low output. The...

Problems solved by technology

However, the breeding technology of apple dwarfing self-root stock seedlings is seriously lagging behind, and the existing breeding technology of apple dwarf self-root stock seedlings in my country cannot meet the needs of the development of the situation.
