Method for breeding non-prick large-fruited sarch

Abstract

The invention belongs to a cultivation method for the seabuckthorn fruit asexual propagation, especially relating to a method for breeding the seabuckthorn fruit with no lunge and big fruit, comprising: employing the sprig growing in the parent tree of 2-3 years old of Liaofu 1 and Liaofu 2 which grows no lunge and big fruit as cutting branch for the asexual propagation, building seed bed and irrigating facilities, proceeding cuttage and management after the cuttage, etc. The seabuckthorn fruit with no lunge and big fruit is the strain with high quality among the seabuckthorn fruit strains, the breeding speed of seedling is high by applying sprig for cuttage, the breeding speed can be increased by employing the water from square pool in the spray irrigation with the average plant height 11 cm higher, ground diameter 0.09 cm wider than that of employing water from deep well in the same year, the plant percent is 95%, 15% higher than former, the survival rater of nursery transplant is 80%, 8% higher than former.

Description

technical field

[0001] The invention belongs to a cultivation method for asexual propagation of seabuckthorn, in particular to a method for breeding seabuckthorn with large fruit without thorns. technical background

[0002] Seabuckthorn is a dioecious wind-pollinated shrub. When breeding with seeds, not only the offspring cannot maintain the excellent traits of the original mother plant, but more than 1 / 2 are male plants. It is difficult to distinguish between male and female before flowering and fruiting. When afforestation It will lead to unreasonable matching of male and female plants, which is not conducive to breeding, waste of land resources, and low economic benefits. Since most of the large-fruited seabuckthorn are artificial hybrids and natural hybrids, seeds are used to sow seedlings to produce differentiation, and the properties are unstable. Therefore, the large-fruited seabuckthorn without thorns Hard branch cuttings and soft branch cuttings are generally used ...

Examples

Embodiment Construction

[0010] The breeding method of thornless and large-fruited seabuckthorn is mainly to use twig cuttings and a series of supporting technologies to industrialize the asexual reproduction of thornless large-fruited seabuckthorn. The specific supporting technologies are as follows: build ear-picking gardens, choose places with flat terrain and good soil quality to build ear-picking gardens, Use Liaofu No. 1 and Liaofu No. 2 thornless and large-fruit varieties for planting at a row spacing of 1.5m and a plant spacing of 1.0m. Topdressing is carried out 3 times a year, watering 5 times, and weeding and loosening the soil 3 times. After the ear material begins to age, it is necessary to increase the seedlings of 1 or 2 years. The seedlings are planted in double rows on large ridges. The twigs used for cutting ears 17 are collected from 1.5 to 2.5-year-old young trees. Fertilize once, spray pesticides to kill harmful insects at the same time, and irrigate thoroughly 3 days before ear pi...
