Problems solved by technology

Therefore, the extraction of wild mabi wood will cause resource depletion and unstable production of camptothecin
[0004] The current main propagation methods of mabi wood are rhizome bud propagation and seed propagation. Rhizome bud propagation is easily subject to quantitative restrictions, germplasm is easy to degrade, and it is easy to carry germs and pests.
Group breeding of seedlings tends to cause high cost and troublesome seedling transportation. At present, seedlings are mainly sown after germination in the greenhouse. Seed germination in the greenhouse requires the construction of a special germination room, which needs special supervision and constant turning. When the temperature and water management are not good, it is easy It will lead to burning seeds and bad buds. Because the new buds are brittle, they are easy to break when turning over. When sowing, due to the concern between buds and buds, it is not easy to sow evenly, and it will cause mechanical damage, broken buds and bad buds, and infection of germs.
So far, there is no experimental research report on the impact of Mabi wood's previous crop varieties on seedling cultivation. There is no basis for the selection of seedbed land, and it is impossible to select the seedbed land. The serious problem of high disease susceptibility and mortality rate; because the seedlings carry germs and pests in the nursery, after transplanting, the root system is easy to rot, and the plants suffer from diseases, resulting in high mortality, high disease susceptibility rate, and widespread spread of diseases and insect pests, which brings great harm to production. to seriously damage
There are also reports of on-demand planting with mabi seeds, but this method is not standardized and cannot meet the requirements of large-scale production
[0005] According to the long-term experimental practice, we have invented a large-scale seedling seedling cultivation in greenhouses, which has low seedling susceptibility rate, strong seedling body, high transplanting survival rate, easy operation, and strong rhizome, which is suitable for the propagation of Mabi wood field seedlings. technology, which overcomes the limitations of existing seedling raising technology

Embodiment 1

[0036] Choose 1 mu of sandy loam on the newly developed flat land in the east-west direction, turn the ground, prepare the ground, and rake the ground in the first winter, build a 2m high greenhouse, open the box at 1.3m, and apply 100kg of compound fertilizer as the base fertilizer when the box surface is flat, and the box surface is fine. Then spread 5cm thick new matching soil on the surface of the car (new wasteland soil: 1:1 ratio of sieved river sand), and level it. Wash the seeds with newly drawn well water to remove the deflated seeds. Before sowing, mabi wood seeds are soaked in 1% mepezamine + 300 times carbendazim solution at a constant temperature for 1 night (12h). Seed plant ash, mix well. Sow on March 5, sow 4kg evenly, cover the new soil with 2cm, spray the car surface with fine mist, and build a 30cm high small arch shed with bamboo chips on the car surface. When the day and night temperature in the greenhouse can be maintained above 25°C, the shed will be r...

Embodiment 2

[0048] Choose 1 mu of paddy field with good drainage in the east-west direction. The previous stubble is rice and sandy soil. In the previous winter, the ground will be plowed, prepared, and leveled. A 2m high greenhouse will be built. Fertilizer 100kg is used as base fertilizer, and the surface of the car is fine. Then spread 5cm thick new matching soil on the surface of the car (new wasteland soil: river sand is 1:1), and level it. Wash the seeds with newly drawn well water to remove the deflated seeds. Before sowing, mabi wood seeds are soaked in 1% mepezamine + 300 times carbendazim solution at a constant temperature for 1 night (12h). Seed plant ash, mix well. Sow on March 5, sow 4kg evenly, cover the new soil with 2cm, spray the car surface with fine mist, and build a 30cm high small arch shed with bamboo chips on the car surface. When the day and night temperature in the greenhouse can be maintained above 25°C, the shed will be removed.

Embodiment 3

[0054] Choose 1 mu of sandy loam on the newly developed flat land in the east-west direction, turn the ground, prepare the ground, and rake the ground in the first winter, build a 2m high greenhouse, open the box at 1.3m, and apply 100kg of compound fertilizer as the base fertilizer when the box surface is flat, and the box surface is fine. Then spread 5cm thick new matching soil (new wasteland soil: slag is 1:1) on the surface of the car, and level it. Wash the seeds with newly drawn well water to remove the deflated seeds. Before sowing, mabi wood seeds are soaked in 1% mepezamine + 300 times carbendazim solution at a constant temperature for 1 night (12h). Seed plant ash, mix well. Sow on March 5, sow 4kg evenly, cover the new soil with 2cm, spray the car surface with fine mist, and build a 30cm high small arch shed with bamboo chips on the car surface. When the day and night temperature in the greenhouse can be maintained above 25°C, the shed will be removed.
