specific Embodiment approach 1

[0023] Specific implementation mode 1: In this implementation mode, the plate-type straw biological seedling raising substrate is prepared according to the following steps:

[0024] 1. Cut off the straw, and then use the plunger screw method to send it into the cooking tank for cooking and softening;

[0025] 2. Grinding and kneading the softened stalks in step 1 to form stalk fibers, and then drying;

[0026] 3. Mix a part of dried straw fiber with solid adhesive and solid water-retaining agent in proportion and send it to the surface silo; mix another part of dried straw fiber with solid nutrient, trace elements, solid adhesive, The solid water retaining agent and solid additives are mixed in proportion and sent to the core silo;

[0027] Four, use the mixture in the silo to pave the plate-type straw biological seedling raising matrix slab;

[0028] 5. After the slab is pre-pressed, it is hot-pressed to obtain a plate-type straw biological seedling-raising substrate;

[0...

specific Embodiment approach 2

[0043] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the solid nutrient is a compound fertilizer, and the mass ratio of the solid nutrient to trace elements is 1:1.5-4. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0044]Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the cut stalks in step 1 are cooked and softened for 2-6 hours at a pressure of 0.3-1.5 MPa and a temperature of 110°C-180°C. minute. Other steps and parameters are the same as those in Embodiment 1 or 2.

[0045] While steaming and softening, high-temperature sterilization is carried out to Pythium straw.

Abstract

The invention relates to a method for preparing a straw seedling culture medium, in particular to a method for preparing a plate-type straw biological seedling culture medium with a dry process. The problems that at present, straw is low in additional value and small in usage amount, and resources are wasted are solved. The preparing method includes the first step of straw cutting-off, stewing and softening, the second step of grinding, rubbing and kneading and drying, the third step of material metering and mixing, the fourth step of laying, and the fifth step of hot-pressing molding. It accords with the concept of returning crop stalks to the field to prepare straw into the seedling culture medium, nutrient substances in straw can be effectively utilized and transformed into organic matter to achieve resource recycling, the dependence on chemical fertilizer is reduced while necessary nutritional ingredients are provided, production and usage cost is reduced, and a new industrial production pattern is provided for base material formation in comprehensive utilization of straw.

Description

technical field [0001] The invention relates to a method for raising seedlings with straw. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. Except for materials for power generation, livestock feeding, and composting, most of them are directly burned because of low added value and are not rationally utilized. The gas generated by burning straw is extremely harmful to the atmosphere: increasing CO in the air 2 content, its CO 2 The proportion of the increase is far greater than the proportion of burning ordinary trees; increasing the inhalable particulate matter in the air is the main factor caus...
