Problems solved by technology

At present, the common rapeseed is a production-type rapeseed that is cultivated and hybridized with round stem-type plants. This kind of rapeseed has very short pods, large pod spacing, small fruit pods, high plant branches, and easy lodging, so the yield is not high.
And it is only limited to the production type. Although it is beautiful, it is common for people to beautify the natural beauty of human nature. There is no natural flavor of newer, more beautiful and more beautiful natural scenery.

Embodiment 1

[0016] Example 1. Brassica napus Guiza No. 4 flat-stem parent A obtained by self-split purification and selection

[0017] Select respectively flat and convenient seed production fields with safe isolation (spatial isolation distance is more than 1.5 kilometers, and other cruciferous crops are not allowed to be planted in the isolation area), and the selected Guiza No. 4 hybrid rapeseed seeds are sown and planted. About 1.5 feet, the nest distance is about 1 foot, use unburned, fine and small pieces of coal gangue rich in more than 3 kinds of mineral elements and more than 3 kinds of trace elements plus appropriate amount of white mud, yellow mud and sandy loam as the base; per square meter The ratio of ingredients is 1: 1: 1: 1. It is made by mixing 15 kg of five-flavored sausage for mu, 40 kg of oil cake, 50 kg of potassium sulfate compound fertilizer, 3 kg of boron fertilizer, 10 kg of potassium fertilizer and more than three kinds of trace amounts. The elemental fertilizer...

Embodiment 2

[0021] Example 2. Purification and breeding of Japanese black pearl flat stem parent B and American rape king flat stem parent C

[0022] Implementation conditions except that the seeds of the seeds respectively are Japanese black pearl conventional rapeseed and American rapeseed king hybrid rapeseed, all the other are the same as embodiment one.

[0023] Japanese Black Pearl is a conventional rapeseed cultivated by Dr. Zeng Ichiro from Pearl Bay Farm in Japan. American Rapeseed King is a new generation of rapeseed hybrid introduced from the United States by Hubei Tianmen Characteristic Agriculture Co., Ltd. The new generation of hybrid rapeseed has a pod length About 13 to 20 cm.

Embodiment 3

[0024] Example 3. Three-line hybridization

[0025] The flat rod parent A obtained in Example 1 was used as the female parent, and the Japanese black pearl flat rod parent B obtained in Example 2 and the American rape king flat rod parent C were used as the male parent for three-line crossing.

[0026] Except for the following differences, the rest are the same as the conventional three-line cross:

[0027] 1) Use unburned fine coal gangue rich in more than 3 kinds of mineral elements and more than 3 kinds of trace elements plus an appropriate amount of white mud, yellow mud and sandy loam as the base; coal gangue, white mud, yellow mud and sandy loam A 1:1:1:1 mix of ingredients per square meter is preferred. 15 kg of five-flavored sausage, 40 kg of oil cake, 50 kg of potassium sulfate compound fertilizer, 3 kg of boron fertilizer, 10 kg of potassium fertilizer and three or more trace element fertilizers are used as base fertilizers. The trace element fertilizer is 2 kg of c...

Abstract

The invention discloses a method for cultivating and breeding tour spectacle rape invented by Mr.Li Xianming in Sichuan Shehongxianming Agriculture High-tech Research Institution. The method comprises the following steps of: selfing Brassica napus Guiza 4, and breeding a flat bar parent A of the Brassica napus Guiza 4 through mitosis and purification; selfing Japanese black pearl conventional rape and American rape king hybrid rape respectively, and breeding a flat bar parent B of the Japanese black pearl and a flat bar parent C of the American rape king through purification; hybridizing three lines, namely the flat bar parent A of the Guiza 4, the flat bar parent B of the Japanese blackpearl and the flat bar parent C of the American rape king to obtain partially multi-flower multi-pod aggregate D; and selfing, purifying and breeding the partially multi-flower multi-pod aggregate D to obtain the tour spectacle rape G. The tour spectacle rape prepared by the method has long pods, more and large grains, and small distance, is particularly peculiar and gorgeous due to multiple flowers on one stem and rare and splendid due to multiple pods on one stem, is particularly suitable for tour scene cultivation and bonsai cultivation and appreciated as tour spectacle and potted plants of streets, home and courtyards, and beautifies natural environment.

Description

technical field [0001] The invention relates to the field of rapeseed, in particular to a method for cultivating and selecting rapeseed with tourist wonders and scenery invented by Mr. Li Xianming. Background technique [0002] Rapeseed is one of the main edible oil crops in the world, and it is also one of the main sources of edible oil for our people. Therefore, rapeseed is a widely planted oil crop in our country. At present, the common rapeseed is a production-type rapeseed that is cultivated and hybridized with round stem-type plants. The pods of this rapeseed are very short, the distance between pods is large, the pods are small, the plant type has high branches, and it is easy to lodging, so the yield is not high. And also only be limited to production type, for beautifying the natural beauty of human nature, although beautiful, also people are common, there is no natural flavor of the high-tech scenery viewing and viewing of more beautiful more beautiful natural scen...
