Cross-breeding method of gerbera jamesonii in sunlight greenhouse tent

Abstract

The invention discloses a cross-breeding method of gerbera jamesonii in a sunlight greenhouse tent. By adopting frame-type substrate culture, fertilizers are applied quantitatively and watering operation is performed according to the plant growth condition.Poorly-growing plants can be separately managed. The cross-breeding method of gerbera jamesonii in the sunlight greenhouse tent has following beneficial effects: diseases are conveniently controlled; when diseases occur in one of frame, plants can be quarantined in order to separate control; diseases do not break out in a large scale; soil-borne diseases such as wilt diseases and root-rot diseases are effectively controlled so that the seed setting number is increased; by adoption of frame-type substrate culture, plants grow robustly in order to favorably raise seed setting number; and according to the breeding need, relative positions of male parents and female parents can be randomly placed so that great practicability is obtained.

Description

technical field [0001] The invention relates to the technical field of plant breeding, in particular to a method for hybrid breeding of gerbera in a solar greenhouse. Background technique [0002] The existing gerbera conventional crossbreeding method is generally planting in August-September, planting in a greenhouse, adopting soil cultivation, blooming in February-March of the second year, and adopting artificial hybridization. The main shortcoming of this method is: 1, disease, insect, weed damage are heavy. Soil cultivation is easy to cause soil compaction and serious diseases due to reasons such as irrigation methods and soil physical properties. In particular, soil-borne diseases such as fusarium wilt and root rot are difficult to control, often causing large-scale death of plants, resulting in the absence of male or female parents. Moreover, insect and weed damage are relatively heavy. 2. The number of seeds set is poor. In the traditional cultivation method, due ...

AI Technical Summary

Problems solved by technology

The main disadvantages of this method are: 1. Diseases, insects and weeds are serious

Soil cultivation, due to reasons such as irrigation methods and soil physical properties, can easily lead to soil compaction and serious diseases.

Especially soil-borne diseases such as fusarium wilt and root rot are difficult to control, often causing large-scale death of plants, resulting in the absence of male or female parents

In addition, pests and weeds are relatively heavy

2. The number of seeds is poor

In the traditional cultivation method, due to the difficult control of nutrients, water and temperature, after hybridization, the number of seeds set is poor, and some are not even fruitful.

3. The male and female parents have fixed cultivation positions, which is not conducive to the collection and isolation of pollen

4. It is difficult to adjust the flowering period of male parent and female parent, and it is not easy to solve the problem of flowering period

Obviously, this method cannot meet the usage requirements
