Example Embodiment

[0021] Example 1

[0022] (1) Use the dry Fructus Aurantii seeds with large and full grains and qualified for quarantine as rootstock seeds, and undergo the following osmotic treatment: a mixture of thiophanate-methyl diluted 1000 times and carbendazim 500 times diluted with a mass concentration of 75%, Soak the rootstock seeds for 20 hours to increase seed vigor, increase seedling emergence rate, and make seedlings emerge neatly;

[0023] (2) Choose a dry land with flat terrain and deep soil layer, and after regular soil preparation, ridging on flat ground with a height of 20cm and a width of 120cm;

[0024] (3) Sow 140kg per mu, sow the dried citrus aurantium seeds of step (1) on the top of the ridge of step (2), cover a layer of soil with a thickness of 5cm after sowing, spray appropriate amount of water to moisturize the seeds , In order to facilitate germination; then cover the soil with a thickness of 3cm river sand to prevent the germination of weeds in the soil; cover the f...

Abstract

The invention relates to a rapid breeding method of lemon stocks. The method comprises the steps of stock seed pretreatment, seedling cultivating bed preparation, ridging and planting, double-film covering as well as transplanting of seedlings with embryos. By using the technical method provided by the invention, problems of low emergence rate, long production time and the like of stock seed seedling planting can be solved; meanwhile, the rapid breeding method of the lemon stocks provided by the invention has the advantages of simplicity, practicability, easiness in operation and short time consumption; and compared with the traditional seedling cultivating method, the rapid breeding method of the lemon stocks provided by the invention has the advantages as follows: the stock seedling cultivating period can be reduced by 30 days, the emergence rate and survival rate of the stocks are greatly increased and the emergence rate can be high up to 85%. The technical method provided by the invention can be also used for producing other citrus stocks.

Description

technical field [0001] The invention relates to a rapid breeding method of lemon rootstock, which belongs to the technical field of plant cultivation. Background technique [0002] Lemon is rich in citric acid, vitamins C, B, P, H, E and flavonoids, volatile oil, hesperidin, various minerals and trace elements, etc. It is a fruit with high nutritional and medicinal value. There are few climatic regions suitable for growing lemons in Asia. my country has relatively large climatic regions, such as Yunnan, Sichuan and Chongqing, which are suitable for the cultivation and growth of lemons. Among the domestic lemons, the average price of first-class and second-class fresh fruit exceeds 4.0 yuan / kg, and the export price is more than 8 yuan / kg, which is much higher than that of ordinary citrus fruits. However, due to the late start of the lemon industry in my country, the national planting area was only about 1,000 mu in 1965. In the late 1970s, large-scale development began in An...
