Embodiment Construction

[0015] On August 15, 2012, a test was carried out in a longan garden in Genzi Town, Gaozhou, Maoming: the test tree was 20-year-old Chuliang longan, and 5 trees with similar conditions were randomly selected for the operation tree and the non-operation tree. Operated trees scrape off the bark in the range of 10 cm in long diameter and 5 cm in short diameter with an electrician's knife at the root neck, reaching the xylem deeply. Mix the plant growth regulator indole butyric acid: water = 150mg: 1kg and pour it into the crushed garden soil, adjust the humidity of the crushed garden soil to a relative humidity of 60%-80%, and then cover the surgical site with the garden soil On, cover thickness 30cm. The tree without surgery was used as a control.

[0016] According to the survey in April 2013, the surgical sites of the 5 trees were all healed, and roots corresponding to the surgical site grew out. The average new root length of the 5 trees was 68 cm, and the result was that th...

Abstract

The invention discloses a method for promoting the new root taking of adult longan trees. The method comprises the steps of scraping off tree bark with a certain area from a root collar portion after longan fruits are harvested, and then covering by garden soil treated by a plant growth regulator for promoting root taking. By using the method for promoting the new root taking of adult longan trees disclosed by the invention, thick roots corresponding to notches in size can grow in positions where a part of the tree bark is cut off at the root collar of the tree body in the next year after the operation, the speed is increased by many times compared with the conventional method for promoting the new root taking of adult longan trees, and the effect is very obvious. Moreover, the method is simple to operate and very beneficial to popularize.

Description

technical field [0001] The invention belongs to a method for promoting new roots of mature longan trees. Background technique [0002] Longan is one of the most important south subtropical woody fruit trees in China. There are more than 7 million mu of longan in the country. It is the country with the largest cultivated longan area in the world. It has played an important role in increasing farmers' income and mountain greening. Longan has a high fruit rate. In high-yield years, the tree vigor is often weakened due to too high yield. There is a folk saying that longan is "you want cubs and not mothers". The root system is the main organ for fruit trees to absorb nutrients and water, and plays a vital role in the normal growth of fruit trees. Promoting longan to take new roots can prevent the tree from weakening and make the weakened longan tree recover quickly. At present, there are mainly the following methods to promote the production of new roots of mature longan. [0...
