Embodiment 1

[0050] The concentration of spraying for the first time is 4mg / kg and the amount is 250kg / hm 0.5 days before the bolting and budding of the northern Radix isatidis 2 The SX-1 chemical hybridization agent, 2 days after the flowering of Radix isatidis, using domesticated Radix isatidis pollen to artificially pollinate Radix isatidis after the first spraying to obtain hybrid Radix isatidis.

Embodiment 2

[0052] The concentration of spraying for the first time is 5mg / kg and the amount is 200kg / hm 1 day before the bolting and budding of the northern Radix isatidis 2 The SX-1 chemical hybridization agent, after the northern isatis root blooms, the second spraying concentration is 6mg / kg, and the amount is 300kg / hm 2 SX-1 chemical hybridization agent, and 4 days after the second spraying, domesticated Radix isatidis pollen was used to artificially pollinate Radix isatidis after the second spraying to obtain hybrid Radix isatidis.

Embodiment 3

[0054] The concentration of spraying for the first time is 4.5mg / kg and the amount is 220kg / hm 0.7 days before the bolting and budding of the northern Radix isatidis 2 The SX-1 chemical hybridization agent, after the northern Radix isatidis blooms, the spraying mass percentage is 0.55%, and the amount is 2000kg / hm 2 NaCl solution, after the second spraying concentration is 7mg / kg, the amount is 250kg / hm 2 SX-1 chemical hybridization agent, and 3 days after the second spraying, domesticated Radix isatidis pollen was used to artificially pollinate Radix isatidis after the second spraying to obtain hybrid Radix isatidis.

Abstract

The invention relates to a hybridizing method of isatis tinctoria / baphicacanthus cusia, and belongs to the technical field of hybridizing breeding. The hybridizing method comprises the following steps of spraying an SX-1 chemical hybridizing agent for the first time 0.5 to 1 day before the isatis tinctoria is bolted and budded; after the isatis tinctoria flowers, using domesticated isatis tinctoria pollen to artificially pollinate the isatis tinctoria after first-time spraying; or, spraying the SX-1 chemical hybridizing agent for the first time 1 to 2 days before the baphicacanthus cusia is bolted and budded; after the baphicacanthus cusia flowers, using domesticated baphicacanthus cusia pollen to artificially pollinate the baphicacanthus cusia after first-time spraying. The hybridizing method has the advantage that by using the SX-1 chemical hybridizing agent, the male pollen of the isatis tinctoria or the male pollen of the baphicacanthus cusia can be killed, so that the hybridized isatis tinctoria / baphicacanthus cusia has enhanced suitability to the environment, and the output is greatly increased.

Description

technical field [0001] The invention relates to the technical field of hybrid breeding, in particular to a hybridization method of Radix isatidis. Background technique [0002] Isatidis is a cruciferous plant with strong heat-clearing, detoxifying and anti-inflammatory effects. Isatidis injection has inhibitory effects on influenza A virus, encephalitis B virus, mumps virus and influenza virus, etc. The main products In Hebei, Jiangsu, Anhui and Shaanxi and other places. Southern Radix Isatidis is a plant of Acanthaceae. Its heat-clearing, detoxifying and anti-inflammatory effects are weaker than those of Northern Radix Radix. Hunan, Jiangxi, Guizhou, Guangdong and Guangxi and other places. [0003] In the prior art, there is no research on hybridization of Radix isatidis. Contents of the invention [0004] The object of the present invention is to provide a hybridization method of Radix isatidis, artificially pollinate the stamens of Radix isatidis domesticated with th...
