Method for breeding strawberry seedlings

Abstract

The invention discloses a method for breeding strawberry seedlings. The method comprises the steps of selecting seedlings, selecting culture land parcels, culturing the seedlings, performing heat insulation and transplanting the seedlings and the like. A scientific, operable and successful planting process mode is provided for planting red strawberries, the technical risk caused to operators in operation and the environmental influence risk are avoided, and successful planting and high yield and efficiency are guaranteed. A secondary synchronous seedling culture method with strawberry stem tip entity separation is adopted, the excellent hereditary character of the original variety is maintained, varietal character degenerate mutation is avoided, the problems of stubborn and destructive diseases such as anthracnose are solved, and it is guaranteed that the seedlings are tidy and robust after the seedling culture success and field transplanting. The yield formation at an earlier stage is guaranteed, continuous fruiting is achieved, and the per-mu economic benefit is maximized.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a breeding method for strawberry seedlings. Background technique [0002] In the prior art, mostly adopt the following several ways to carry out the breeding of strawberry seedlings: A, adopt detoxification breeding, promptly the strawberry stolon tip in the field growth is taken back indoor, takes off the top and cultivates and proliferates indoors, and then passes through 3 After level multiplication, seedlings for production are provided. The biggest problem of seedling propagation in this way is that the seedling propagation time is as long as more than 3 years, which cannot meet the market demand for new seedlings. Second, the cost of breeding seedlings is high. According to a rough calculation, it costs about 6-7 yuan to cultivate a core seedling in the laboratory, and about 3-5 yuan for a farmer to buy an original seedling, and the cost of see...

AI Technical Summary

Problems solved by technology

The biggest problem with seedling propagation in this way is that the seedling propagation time is as long as more than 3 years, which cannot meet the market demand for new seedlings

Second, the cost of breeding seedlings is high

The third is that it is difficult to moderately control the dosage of hormones in tissue culture, resulting in large variation in strawberry species, and it is easy to cause deformed fruits after planting in the field.

The biggest problem with seedling propagation in this way is that the disease is serious, which makes it difficult for the seedlings to survive. Even if the seedlings survive and are planted in the ground, due to the large amount of bacteria in the seedlings, the dead seedling rate is high, generally more than 30%, or even discarded. plant

The second is that due to the poor reproductive activity of the stolons of old seedlings, the root system activity of the grown seedlings is poor after transplanting, and the slow seedling period is long, which affects the normal development progress of the seedlings.

The third is that the seedlings have poor stress resistance, disease resistance and self-regulation ability in the field

Fourth, the amount of fruit in the early stage is small, the proportion of deformed fruit is large, and the taste and flavor of the fruit are poor

Occasionally results in a gap

Fifth, the commerciality of the fruit is poor, and the average benefit per mu is low
