African agropyron (academic Linn.) is an annual or biennial herb of the family Aizoaceae, genus Flora. The wheatgrass is a halophyte originally produced in Africa and the like, a large number of large-scale bubble-shaped cells are grown on leaf surfaces and stems, liquid is filled in the cells, and the cells are glittering and translucent under the irradiation of sunlight just like ice crystals, so the wheatgrass is named. The wheatgrass is a novel vegetable introduced from Japan in recent years, and is a vegetable with high nutritional value because of the unique flavor and ice crystal appearance, and the wheatgrass is rich in natural plant salt, amino acid, carotene and other substances, thereby quenching thirst and supplementing nutrient salt after eating. Is popular with the catering industry and consumers. At present, the wheatgrass seeds are mainly imported and expensive, the price reaches 0.2-0.5 yuan/grain, and is converted into more than 120 ten thousand yuan/kg, so that the planting cost of farmers is improved. The wheatgrass seeds are extremely tiny, about 1.6 g/ten thousand seeds with the diameter of about 0.3mm, are not easy to find, have high salt content on the wheatgrass seed coats, have strong moisture absorption and are easy to flash buds during seedling culture. Therefore, the difficulty in collecting the wheatgrass seeds is caused, the seed germination rate is low, the seed cost is high, and the planting cost of farmers is increased.
If a simple and effective method is available for obtaining the wheatgrass seeds, the method is not only beneficial to the popularization and planting of the novel vegetables, but also can reduce the seed cost of farmers and increase the production benefit. In addition, the wheatgrass can be used for planting in saline-alkali soil treatment, and a large amount of salt in the soil is absorbed and the soil structure is improved by planting the wheatgrass, so that the market has great demand on wheatgrass seeds.
The invention designs a vegetable wheatgrass seed collection method, which finally obtains high-quality clean wheatgrass seeds through the steps of crushing, washing, leaching, precipitating, airing and the like, and has the advantages of high cleanliness, high germination rate and low seed cost, and meanwhile, the planting cost of farmers is reduced.

(2) seed collection: in the first ten days of April, the wheatgrass in the greenhouse is topped, the seeds which blossom and bear fruits are removed, and monopotassium phosphate is sprayed on the leaf surfaces twice; after the wheatgrass plants are mature, harvesting the part of the ground more than 10cm, and transporting back;
(3) crushing and washing with a feed crusher: crushing the wheatgrass transported back in the step (2) into straws of 0.5-1 cm, placing the straws in a plastic barrel, injecting clear water, stirring, rinsing the straws floating on the water surface, naturally precipitating wheatgrass seeds to the bottom of the barrel, and repeating the steps for three times;
(4) drying the seeds: after water is filtered out, the seeds are thinly and evenly spread in a plastic plate, placed in an air-conditioning room at the temperature of 30 ℃ and dried within 1 hour;
(5) and (3) testing the purity, water content and germination rate of the seeds: packaging the tested qualified seeds, and putting the seeds into a refrigerator for later use; in the step (3), the water washing process is fast and is completed within 1 hour.
The washing process takes too long time to make the seeds absorb water and germinate, thereby affecting the germination rate of the commodity; the typical high-quality wheatgrass in the step (1) has the characteristics that: the plant height is 30-50 cm; a binary branch; big round leaves; the ice crystals are excessive; purple growth point and the like; the depth of the sowing in the step (2) is less than 1cm, base fertilizer is applied before the wheatgrass is planted in the greenhouse, the temperature in the greenhouse is 20 ℃, and the air humidity is 50%; soil mixed by leaf mold and vegetable garden soil is adopted when the wheatgrass is planted in the greenhouse in the step (2); the diameter of the qualified seeds in the step (5) is 0.4mm, the purity is more than 98%, the purity is more than 99%, and the germination rate is more than 85%; 5 kilograms of bone meal and 2.5 kilograms of sodium chloride can be added into the soil per mu; the base fertilizer is a mixture of a nitrogen-phosphorus-potassium compound fertilizer and a farmyard organic fertilizer; the components of the farmyard organic fertilizer consist of chicken manure, rapeseed cakes and straw waste; the composition ratio of the chicken manure, the rapeseed cake and the straw waste is 3:2: 1; the planting of the wheatgrass can obtain high yield and improve the saline-alkali soil.
The comparison of the above examples 2 to 4 shows that the temperature and humidity have a large influence on the diameter and germination rate of the seeds, and therefore, the proper temperature and humidity need to be maintained when the wheatgrass is planted.
Finally, it is also noted that the above-mentioned lists merely illustrate a few specific embodiments of the invention. It is obvious that the invention is not limited to the above embodiments, but that many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the invention.
