Embodiment 1

[0053] The present embodiment provides a composite porous substrate for planting Cistanche deserticola. In parts by weight, its raw materials include: 100 parts of crop waste, 20 parts of clay, 1 part of soil conditioner and 1 part of gypsum; wherein, the crop waste consists of corncobs and beans Straw composition, the mass ratio of the two is 5:2.

[0054] The preparation method of the composite porous substrate is as follows:

[0055] (1) Take corn cobs and bean stalks (corn cobs: bean stalks = 5:2) in a mass ratio of 5:2, mix them, and coarsely crush them into mixed particles with a particle size of 2 to 3 cm.

[0056] (2) Spray water evenly after the above coarsely crushed mixed particles are stacked, and keep stirring during the water spraying process. When the water content per 100g of the mixed particles reaches about 70%, stop spraying water and stirring, put the mixed particles in a sterilizing pot, and sterilize at 0.04-0.06M, 105-110°C for 1-1.5 hours.

[0057] (3...

Embodiment 2

[0060] This embodiment provides a method for inoculating Cistanche deserticola using the composite porous substrate of Embodiment 1, which includes the following steps:

[0061] (1) Spray water on the monolithic composite porous substrate prepared in Example 1 to make it fully wet, and stop when the moisture content of the substrate reaches 50% to 60%.

[0062] (2) Take 2 composite porous substrates that have been sprayed with water, and evenly place 20 Bacillus amyloliquefaciens slow-release granules (including Bacillus amyloliquefaciens EZ99) in the middle of the round surface, and the number of effective viable bacteria is ≥ 500 million / gram, purchased from Gansu Shangnong Biotechnology Co., Ltd.) and 200 Cistanche seeds, and then pressed and fully compacted.

[0063] (3) Digging pits until 50-60cm deep at the main root position on one side of the host plant (Haloxylon), exposing the lateral roots, and the composite porous base material containing Cistanche seeds after th...

Embodiment 3

[0066] The inoculation method of Cistanche deserticola provided in this example is basically the same as that in Example 2, except that the host plant is Tamarix.

Abstract

The invention discloses a composite porous substrate for cistanche deserticola planting and a preparation method and an inoculation method thereof, and relates to the technical field of cistanche deserticola planting. The composite porous substrate comprises crop waste, clay, a soil conditioner and gypsum. The composite porous substrate can promote root development of host plants, induce root growth of the host plants to wind the composite porous substrate material, increase stimulation of host root exudates to cistanche seeds to promote germination and form aspirators, and increase the contact probability of the germinated seeds and the root so that more aspirators penetrate through the root of the host plants to complete inoculation, and the inoculation rate is improved.

Description

technical field [0001] The invention relates to the technical field of Cistanche planting, in particular to a composite porous substrate for planting Cistanche and its preparation method and inoculation method. Background technique [0002] Cistanche is a tall herbaceous parasitic plant that parasitizes on the roots of desert plants Haloxylon or Tamarix. It is 40-160 cm high and mostly grows underground. Known as "Desert Ginseng", Cistanche deserticola has extremely high medicinal value and is a traditional Chinese medicinal material. At present, the total annual demand for Cistanche in the domestic and international markets is over 4,500 tons, while the domestic Cistanche basically comes from wild resources, and the annual supply is only 500-600 tons, so the contradiction between supply and demand is extremely prominent. Due to over-harvesting, the resources of Cistanche are on the verge of depletion. It has been listed as a second-class national protected plant in China a...
