Embodiment 1

[0045] Embodiment one: at NaCl concentration, be 0.60% to carry out the seed of different varieties of saline-alkali stress experiment, in saline-alkali land salt content 2.0g·kg -1 When planting, the overwintering traits of planting growth;

[0046]

Embodiment 2

[0047] Embodiment two: be that 0.60% carry out the seed of different varieties of saline-alkali stress experiment at NaCl concentration, in saline-alkali land salt content 4.0g·kg -1 When planting, the overwintering traits of planting growth;

[0048] Plant height (cm) Effective branch point density (cm) Main shaft length (cm) A species 139.5 3.0 45.2 Type B 149.0 3.2 54.2 C variety 149.2 3.4 58.2

Embodiment 3

[0049] Embodiment three: be that 0.60% carry out the seed of different varieties of saline-alkali stress experiment at NaCl concentration, in saline-alkali land salt content 6.0g·kg -1 When planting, the overwintering traits of planting growth;

[0050] Plant height (cm) Effective branch point density (cm) Main shaft length (cm) A species 135.3 3.4 45.2 Type B 143.5 3.6 52.3 C variety 145.7 3.8 55.4

[0051] In summary, when the seeds of different varieties are subjected to saline-alkali stress experiments in 0.60% NaCl solution, the germination of seeds, seedling root activity, and soluble protein content are the best, and their salt content in saline-alkali land is 2.0g kg -1 When planting at the same time, the overwintering properties of the seeds are the best when planting, and the seeds of the C variety have the best overwintering properties, followed by the B variety.

[0052] Select the seeds of B variety and C variety, repe...

Abstract

The invention belongs to the technical field of screening of rape varieties in saline-alkali soil, and particularly relates to a method for screening strong-salt-resistant germplasm of Brassica rapa. The problem that the salt-resistant effect of Brassica rapa varieties planted in the saline-alkali soil is poor when the Brassica rapa varieties are screened is solved. According to the following scheme, the method comprises the following steps that S1, hydroponic primary selection is carried out; S2, saline-alkali stress is simulated; S3, salt-resistant varieties are screened; S4, a saline soil test is carried out; S5, determining is carried out; and S6, overwintering characters are analyzed and determined. According to the method, after multiple varieties of Brassica rapa are subjected to hydroponic primary selection, Brassica rapa seeds with excellent quality underground in non-saline-alkali soil are selected, the excellent quality of the Brassica rapa seeds is subjected to a simulated saline-alkali stress test, the growth traits of the Brassica rapa seeds in saline-alkali soil with different salt contents are determined, overwintering planting is carried out on the saline-alkali soil land, the high-salt-resistance brassica rapa is screened out according to the plant type growth condition, the screening operation process is simple, multiple varieties are selected, and the selection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of screening rapeseed varieties in saline-alkali land, in particular to a screening method for strong salt-resistant germplasm of Chinese cabbage-type winter rapeseed. Background technique [0002] Rapeseed is an oil crop with a wide range of saline-alkali tolerance and adaptability. Rapeseed has a large biomass, which can not only increase soil organic matter, but also improve soil fertility, promote soil improvement in saline-alkali land, and improve the soil environment. At the same time, it is equipped with corresponding agricultural machinery and equipment It is of great significance to solve the problem of unstable quality of rapeseed scattered planting and improve the degree of mechanized operation of rapeseed and the effect of large-scale planting. [0003] When different rapeseed varieties are cultivated on coastal saline-alkali land, due to the different salinity and alkali content in the cultivate...
