Problems solved by technology

Korla fragrant pears are only commercially cultivated in the Korla area of ​​Xinjiang, and there is no large-scale Korla fragrant pear cultivation base in the mainland. The Suzhong area of ​​Jiangsu is the intersection of the north and south pear producing areas in my country, and has good light and heat conditions suitable for Korla fragr...

Embodiment Construction

[0029] The Korla fragrant pear virus-free seedling local breeding technology is characterized in that it comprises the following steps:

[0030] 1) Fragrant pear grafting seedlings

[0031] a. Site fertilization: choose fertile soil and plow 30-40cm deep, apply 3-4 m3 of organic fertilizer per acre, or 1 m3 of decomposed chicken manure or 100-200 kg of cake fertilizer. m, the furrow should be leveled;

[0032] b Rootstock cultivation: use Du pear and Dou pear as grafting rootstocks. Before sowing, the seeds of Du pear and Dou pear are stored in a 4°C refrigerator for sand storage and stratification. 3 m×4m, cover the soil with straw or plastic film, remove the seeds after they germinate and emerge from the soil, or make an opening to make the seedlings grow;

[0033] c Field management: When the temperature reaches 9°C in spring, the apical membrane will start to germinate in about 10 days, and a small hole will be made at the apical membrane to lead the seedlings...

Abstract

The invention provides a local breeding technology for the virus-free seedling of Korla pear. The technology comprises the following steps: 1) raising the seedling of Korla pear by grafting; 2) raising the virus-free seedling by using the stem tip of Korla pear; 3) carrying out T-shaped bud grafting; and 4) cultivating Korla pear by using a flat shed net rack. According to the invention, through virus-free cultivation and micro-grafting of the stem tip of Korla pear, virus-free cultivation of the seedling of Korla pear is realized and the high-quality Korla pear seedling is produced; since appropriate rootstocks are selected from local Korla pear rootstocks, a cultivation model for Korla pear applicable in acidic soil is established; and since Korla pear has a shed frame shape, ventilation and light transmission are realized, strong wind resistance and high fruit quality are obtained, and management is easy.

Description

technical field [0001] The invention relates to the field of fruit breeding, in particular to a local breeding technology for virus-free seedlings of Korla fragrant pears. Background technique [0002] Korla fragrant pear (hereinafter referred to as fragrant pear) is a famous specialty in Xinjiang. Because of its crispy meat, juicy and sweet taste, the supply in domestic and foreign markets has been in short supply. Korla fragrant pears are only commercially cultivated in the Korla area of ​​Xinjiang, and there is no large-scale Korla fragrant pear cultivation base in the mainland. The Suzhong area of ​​Jiangsu is the intersection of the north and south pear producing areas in my country, and has good light and heat conditions suitable for Korla fragrant pears. However, industrial development needs to solve the problem of lack of non-toxic seedlings and suitable rootstocks in the acidic soil in the south. At the same time, it is necessary to adopt protected cultivation...
