Problems solved by technology

[0003] Although the oily bean can be used in different fields, and is superior to many existing economic crops, showing the characteristics of "whole body", but the unique granular shape and hard shell of the oily bean itself, when used as a raw material , peeling is more difficult, which is one of the reasons why it cannot be widely promoted in different fields
Not only that, because it has a hard shell, it also greatly affects the germination rate during planting. As a result, the current germination rate of oily bean planting is only maintained at about 50%, and the survival rate after subsequent planting is also relatively low. This has also become a bottleneck affecting large-scale promotion across the country after being imported from abroad

Embodiment 1

[0030] Embodiment 1 A kind of method that improves the germination rate of Yousha bean

[0031] (1) Select oil-sand beans without pests and diseases and no damage as the test sample, then soak the oil-sand beans in a solution of 4.3% white vinegar by volume fraction, heat to 35°C, stir at a constant temperature and low speed at 60rpm for 1 hour, and obtain pretreated oil-sand beans .

[0032] The white vinegar solution should not be too high or too low. If it is too low, it will not have a bactericidal effect. If it is too high, it may quickly corrode the shell of the oily bean, and may damage the inside of the seed structure or its nutrients, which is not conducive to germination; the heating temperature and stirring speed are also In order to assist in the preliminary softening of the hard shell, the temperature should not be too high or too low to avoid affecting the internal nutrients or not having a stimulating effect; and the stirring speed is too low is not conducive to...

[0041] Embodiment 2 A kind of method that improves the germination rate of Yousha bean

[0042] (1) Select oil-sand beans with no pests and diseases and no damage as test samples, then soak the oil-sand beans in a solution of 4.8% white vinegar by volume fraction, heat to 37°C, stir at 80rpm at a constant temperature and low speed for 1.5h, and obtain pretreated oil-sand beans bean.

[0043] (2) After the pretreated oily bean is taken out and the surface water is drained under aseptic conditions, according to the mass ratio of oily bean: distiller's grains: wood-rot fungus is 100g: 120g: 4g, distiller's grains and wood-rot fungus are added, and mixed fermentation culture 10-12h;

[0044] Prepare distiller's grains according to the following method before use: expose fresh liquor distiller's grains to the sun for 2.5 days on a sterilized site, then mix according to distiller's grains: water mass volume ratio of 1g: 1mL, and adjust pH with 4% quicklime water The value is 5.5.

[0050] Embodiment 3 A kind of method that improves the germination rate of Yousha bean

[0051] (1) Select oily beans with no pests and diseases and no damage as the test sample, then soak the oily beans in a solution of 5.5% white vinegar by volume fraction, heat to 40°C, stir at a constant temperature and low speed at 100rpm for 2 hours, and obtain pretreated oily beans .

[0052] (2) After the pretreated oily bean is taken out and the surface water is drained under aseptic conditions, according to the mass ratio of oily bean: distiller's grains: wood-rot fungus is 100g: 150g: 5g, distiller's grains and wood-rot fungus are added, and mixed fermentation culture 12h;

[0053] Prepare distiller's grains according to the following method before use: expose fresh liquor distiller's grains to the sun for 3 days on a sterilized site, then mix according to distiller's grains: water mass volume ratio of 1g: 1mL, and adjust pH with 5% quicklime water The value is 6.5.

Abstract

The invention discloses a method for increasing the germination rate of cyperus esculentus, which belongs to the field of agricultural planting. The method comprises the following steps of (1) soaking cyperus esculentus in a white vinegar solution, and stirring at a low speed to obtain pretreated cyperus esculentus, (2) taking out the pretreated cyperus esculentus, draining the surface moisture under a sterile condition, adding vinasse and wood-rotting fungi, and carrying out mixed fermentation culture for 10-12 hours, (3) after the fermentation in the step (2) is completed, washing the cyperus esculentus, soaking the cyperus esculentus in 10-20 mg / L 6-BA for 30-60 minutes, and taking out, and (4) sowing the soaked and taken-out cyperus esculentus into a liquid cottonseed meal matrix, and carrying out germination culture at 20-23 DEG C. By optimizing the germination conditions of the cyperus esculentus, the germination rate of the cyperus esculentus and the survival rate of the transplanted cyperus esculentus are remarkably increased, and scientific guidance and test basis are provided for popularization and planting of the cyperus esculentus.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for increasing the germination rate of the oily bean. Background technique [0002] Oil sedge is a plant of the sedge genus, which is native to Northeast Africa. After being introduced to China, it is planted in Xinjiang, Inner Mongolia, Northeast China, North China and other regions. Yousha beans, also known as tiger nuts, are known as "underground walnuts" and "king of oil crops". Oil, food, brewing, medicine, feed, bioenergy, etc. [0003] Although the oily bean can be used in different fields, and is superior to many existing economic crops, showing the characteristics of "whole body", but the unique granular shape and hard shell of the oily bean itself, when used as a raw material , peeling has greater difficulty, which is also one of the reasons why it cannot be widely promoted in different fields.
