Embodiment 1
[0034] In February 2012, the detoxified test-tube seedlings of Qiyam were transplanted on the vermiculite seedbed in the greenhouse with a density of 350 plants / m 2 , a total of 50m2 , 17,500 seedlings, when the seedlings grow to 5-6 flat leaves, when the height of the seedlings is 7-9cm, start cutting propagation according to the above-mentioned technical plan method, count 2-3 leaves from the base and cut off the top for cuttings, after 10 days Cutting once more, each test tube seedling can be cut twice on average, and the planting area of the final seedbed reaches 150m 2 , a total of 52,500 plants, and a total of 62,450 Qiyam detoxified miniature beans were harvested at the end of April. According to the density of 7000 plants / mu of the original seed produced under the isolation condition, the field of 8.9 mu can be sown. If it is calculated as 3 stubbles a year, it can provide 8.9×3=26.7 mu of Qiyam original seed production.
Embodiment 2
[0036] In February 2012, the Qiyam detoxification test tube and zero-surplus seedlings were transplanted on the vermiculite seedbed in the greenhouse with a density of 350 plants / m 2 , a total of 50m 2 , 17,500 seedlings, when the seedlings grow to 5-6 flat leaves, and the height of the seedlings is 7-9cm, start cutting propagation according to the above method, count 2-3 leaves from the base, cut off the top for cutting, and then cut after 10 days Once, each test-tube seedling can be cut twice on average, and the planting area of the final seedbed reaches 150m 2 , a total of 52,500 plants, and a total of 60,340 Qiyam detoxified miniature beans were harvested at the end of April. According to the density of 7000 plants / mu of original species produced under isolation conditions, 8.6 mu of fields can be sown. If it is calculated as 3 crops a year, it can provide 8.6×3=25.8 mu of Qiyam original seed production.
