Problems solved by technology

[0004] However, because tartary buckwheat seeds are not resistant to storage, their viability decreases rapidly. Generally, the germination rate is only about 40-60% when stored for more than two years, and the emergence rate is even lower.
In order to ensure a certain emergence rate, it is often necessary to overseed during production, but on the one hand, this will easily lead to uneven density, which is not conducive to the high yield of tartary buckwheat; on the other hand, the amount of seeds used is too large, which will increase the production cost.
These have seriously affected the production of tartary buckwheat
[0005] In the current agricultural planting technology, there is no simple and effective method to improve the emergence rate of tartary buckwheat

Embodiment 1

[0036] Embodiment 1: Chuan Qiao No. 1 sowing test

[0037] Chuanqiao No. 1, a tartary buckwheat variety mainly planted in a large area in Southwest China, was used in the experiment, provided by Zhaojue Agricultural Science Research Institute of Liangshan Yi Autonomous Prefecture, Sichuan. The experiment adopts a two-factor randomized block design, using Chuanqiao No. 1; using endophytic fungus Fatf6 mycelia to extract polysaccharides to soak and induce tartary buckwheat seeds, and then let the seeds naturally dry for 3-5 hours. Set factor B as the concentration of endophytic fungal polysaccharide soaking seeds, B1: no soaking as the control (CK); B2: 100ppm; B3: 200ppm; B4: 400ppm; B5: 800ppm. Set up a community area of ​​7.6m 2 (2m×3.8m), 20 rows per plot, row spacing 19cm, row length 2m, hole spacing 20cm, 10 points per row. The test adopts hole sowing, 10 seeds per hole, and 300kg / hm before sowing 2 Apply compound fertilizer (N:P:K=20:7:18) at the bottom, and cover with...

Embodiment 2

[0041] Embodiment 2: No. 1 sowing test of Xiqiao

[0042] The tartary buckwheat variety Xiqiao No. 1, which is mainly planted in a large area in Southwest China, was used in the experiment, provided by Xichang University. The experiment adopts a two-factor randomized block design, using Xiqiao No. 1; using the tartary buckwheat endophytic fungus Fat6 mycelia to extract polysaccharides to soak and induce tartary buckwheat seeds, and then let the seeds naturally dry for 3-5 hours. Set factor B as the concentration of endophytic fungal polysaccharide soaking seeds, B1: no soaking as the control (CK); B2: 100ppm; B3: 200ppm; B4: 400ppm; B5: 800ppm. Set up a community area of ​​7.2m 2 (1.6m×4.5m), 30 rows per plot, row spacing 15cm, row length 1.6m, point spacing 16cm, 10 points per row. The test adopts hole sowing, 10 grains per hole, 420kg / hm before sowing 2 Apply compound fertilizer (N:P:K=20:7:18) at the bottom, and cover with 2cm of soil after sowing. Other management meas...

Abstract

The invention relates to the technical field of agriculture, and discloses a method for increasing the emergence rate of fagopyrum tataricum seeds. The method comprises the following steps of extracting polysaccharides from a strain with the preservation number of CGMCC No.10101, then preparing a polysaccharide solution for soaking the fagopyrum tataricum seeds and dibbling the soaked seeds in a sowing season. According to the method, the fagopyrum tataricum seeds are pretreated by virtue of polysaccharides of endophytic fungi, so that the germination and emergence capability of the fagopyrum tataricum seeds is improved; the fagopyrum tataricum seeds are sown by virtue of a dibbling technology, so that the emergence rate of the fagopyrum tataricum seeds is increased; compared with an existing excessive sowing method for ensuring the emergence rate, the method has the advantages that the seeds are reasonable and uniform in density and the method is favorable for high yield of fagopyrum tataricum on one hand, and on the other hand, the sowing quantity and the production cost can be reduced and the method can be popularized and applied on a large scale.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for improving the germination rate of tartary buckwheat seeds. Background technique [0002] Buckwheat belongs to the dicotyledonous plant of Polygonaceae, and buckwheat has two cultivated species, namely sweet buckwheat (Fagopyrumesculentum) and tartary buckwheat (Fagopyrum tataricum). Buckwheat originated in China. Sweet buckwheat is mainly distributed in Inner Mongolia, Shaanxi, Gansu and Ningxia areas north of the Qinling Mountains in my country. Tartary buckwheat is mainly distributed in alpine and hilly areas such as Yunnan, Guizhou and Sichuan. [0003] The scientific name of tartary buckwheat is Tatar buckwheat, and it is also known as buckwheat seven, wild blue buckwheat, Wannian buckwheat, spinwheat, umami, and flower buckwheat. The nutritional value of tartary buckwheat is much higher than that of sweet buckwheat, especially the content of bioflavonoids...
