Problems solved by technology

In agricultural production, the existence of hard seeds hinders seed germination. Artificial sowing and seedling cultivation will prolong the emergence time, which will easily cause seedling shortage or uneven emergence. Moreover, the soil in arid areas is easy to dry up, which will inevitably increase the number of irrigation times, increase the difficulty of management, and affect production. cause direct impact

Embodiment 1

[0023] Manually collect the camel thorn fruit, put it into a woven bag and take it to the botanical garden for drying in the shade, turn it 2-3 times a day, after the fruit is fully dry, beat the camel thorn fruit with an elastic stick, and after more than 90% of the seeds fall off, use a dustpan Screen out large and small impurities, pour the remaining seeds and similar impurities into the water, the seeds with full grains sink into the water, and the impurities and damaged seeds flow out with the water. After several times of water selection, the obtained seeds are placed in cement The ground can be dried and bagged for storage. Before the test, soak the tested seeds in a 500mL beaker with distilled water, put them in a constant temperature incubator at 25°C, change the water 2 to 3 times a day, and remove the seeds with broken seed coats or poorly imbibed seeds in time until they grow again. The hard seeds were dried naturally in the laboratory until there was no seed imbib...

[0028] Before the experiment, soak the tested seeds in a 500mL beaker with distilled water, place them in a constant temperature incubator at 25°C, change the water twice a day, and pick out the seeds with cracked seed coats or poorly imbibed seeds in time until there are no more seeds The hard seeds were dried naturally in the laboratory until imbibition. Select robust, plump, non-damaged and pest-free camel spines as experimental materials, sterilize them with 0.5% potassium permanganate solution for 5 minutes, then rinse them with distilled water and dry them for later use; the prepared concentration is 0.1g / ml~0.2 g / ml of gibberellin GA3, the sterilized camel thorn seeds were soaked with gibberellin GA3 for 24h under total darkness; then the camel thorn seeds were placed in a petri dish covered with 2 layers of filter paper, distilled water was added, and placed Germination was carried out in an incubator in complete darkness at 25°C. After 10 days of germination observat...

[0030]Before the test, soak the tested seeds in a 500mL beaker with distilled water, place them in a constant temperature incubator at 25°C, change the water twice a day, and remove the seeds with cracked seed coats or poorly imbibed seeds in time until there are no more seeds Until imbibition, dry the hard seeds naturally in the laboratory, put the dry hard seeds in a beaker, then slowly pour 98% concentrated sulfuric acid, the weight ratio of concentrated sulfuric acid to seeds is 6:1, rinse with tap water after 10 minutes of treatment 4 to 5 times, rinse with distilled water 3 times and set aside. Choose a petri dish with a caliber of 100mm, first wash the petri dish with tap water twice, then wash it with distilled water for three times, then dry it in an oven at 80°C for 2 hours, spread two layers of filter paper in the petri dish, each petri dish Put into 50 seeds of the concentrated sulfuric acid treatment of step S3, then add the NaCl solution of 6 concentrations of eq...

Abstract

The invention discloses a method for breaking hard seeds of alhagi sparsifolia and determining salt tolerance of hard seeds during germination. The method comprises the following operating steps: S1,harvesting seeds; S2, cleaning the seeds; S3, storing the seeds; S4, breaking the hard seeds; S5, determining the natural germination rate of the seeds and a germination rate of the broken hard seeds;and S6, determining the salt tolerance of the seeds during germination. The method disclosed by the invention has the beneficial effects that the method provided in the scheme is practicable, has excellent operability, and can achieve effects of obviously improving the germination rate of the alhagi sparsifolia seeds, reducing the cost and determining the salt tolerance of the alhagi sparsifoliaseeds during germination in a short time.

Description

technical field [0001] The invention relates to the field of methods for measuring the salinity of camel thorn hard seeds, in particular to a method for breaking camel thorn hard seeds and measuring their salt tolerance in the germination period. Background technique [0002] Camel thorn (Alhagi sparsifolia) belongs to the leguminous family Camel thorn genus salt-tolerant taproot semi-shrub, salinized lowland meadow plant. Camel thorn has a well-developed root system, is resistant to salinity, drought, and stress, and is a dominant plant species in saline lowland meadows. In my country, camel thorns are mainly distributed in Inner Mongolia, Gansu, Ningxia and Xinjiang; they are also distributed in the former Soviet Union, Iran, Afghanistan, Pakistan and India. Camel thorn is a good palatable pasture. Camel likes to eat it all seasons, especially after frost. In spring, fresh grass cattle prefer to eat it. Camel thorn grows on fixed or semi-fixed sand dunes, with well-develo...
