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 ...

Problems solved by technology

[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 for breeding, and the survival rate of seedlings raised by hard branch cuttings is low, so thornless large-fruited seabuckthorn is mostly propagated by soft branch cuttings

In the third issue of "China Soil and Water Conservation" in 1998, "Key Points of Rapid Propagation Technology of Seabuckthorn Twig Cuttings without Thorns and Large Fruits" written by the inventor was published, and Fuxin was published in the fourth issue of Volume 2 of "International Seabuckthorn Research and Development". The two articles "Experimental Research on Cuttage Raising Seedlings of Excellent Seabuckthorn Twigs in Russia" published by the Municipal Forestry Research Institute both introduced the cutting propagation methods of thornless and large-fruited seabuckthorn twigs, but there are imperfect measures and unmatched breeding techniques. However, the shortcoming of the above-mentioned disadvantages is that the ear-picking nursery introduced in the article "Technical Key Points for Rapid Propagation of Seabuckthorn Cuttings with Large Fruits" needs to build plastic greenhouses, which is time-consuming and labor-intensive, and increases the cost. It is not good, and deep well water is used for irrigation, and low water temperature is not good for seedling growth; in the article "Experimental Research on Cutting Seedlings of Excellent Seabuckthorn Twigs in Russia", it is introduced that seabuckthorn seedlings after cuttings are irrigated with square pond water, seedbed structure, fertilization, etc., which are just experiments. The process cannot be used for industrial production of thornless large-fruited seabuckthorn seedlings
