Embodiment 1
[0041] The variety to be tested is "Wen 85-5", which is widely used in production, and "Zongzai" of Rehmannia glutinosa with a length of 3-4 cm and basically the same size is selected. It was carried out in the experimental base of the Agricultural Science Institute of Wenxian County, Jiaozuo, Henan Province, the authentic production area of Rehmannia glutinosa.
[0042] A kind of substratum cultivation method of the present invention to reduce the obstacle of Rhizoma Rhizoma Rhizoma Rhizoma Rhizoma Rhizoma Rehmanniae Rhizome is carried out according to the following steps:
[0043] The first step, soil sterilization treatment before planting: after harvesting Rehmannia glutinosa in the first year, perform autumn plowing at a depth of 30 cm, and apply 4 000-5000 kg / mu of decomposed organic fertilizer, and apply about 150 kg of cake fertilizer per mu in late March of the next year. kg; plow shallowly after irrigation, and rake flat to make furrows; furrows are 120 cm wide, 15...
Embodiment 2
[0049] The variety to be tested is "Wen 85-5", which is widely used in production, and "Zongzai" of Rehmannia glutinosa with a length of 3-4 cm and basically the same size is selected.
[0050] A kind of substratum cultivation method of the present invention to reduce the obstacle of Rhizoma Rhizoma Rhizoma Rhizoma Rhizoma Rhizoma Rehmanniae Rhizome is carried out according to the following steps:
[0051] The first step, soil sterilization treatment before planting: after harvesting Rehmannia glutinosa in the first year, perform autumn plowing at a depth of 30 cm, and apply 4 000-5000 kg / mu of decomposed organic fertilizer, and apply about 150 kg of cake fertilizer per mu in late March of the next year. kg; plow shallowly after irrigation, and rake flat to make a furrow; the furrow is 120 cm wide, 15 cm high, and 30 cm apart, and a ridge is made on the furrow, with a ridge width of 60 cm; soil sterilization treatment is carried out before planting, and the volume fraction is 0...
Embodiment 3
[0057] The step with embodiment two is basically the same, and the difference is that the substrate used is peat and vermiculite, and the volume ratio of peat: vermiculite added is 7:3, and the specification of the nutritional bowl that adopts is 10cm in diameter, 10cm high, specifically The results are shown in Table 4.
