Embodiment 1

[0029] This embodiment provides a straw biomass seedling raising tray, the raw material composition of which is: 100 kg of fermented corn straw; 10 kg of water; 1 kg of wood vinegar, and 0.2 kg of carbon-based fertilizer.

[0030] Wherein, the preparation method of the fermented product of corn stalks is as follows: dry the corn stalks until the water content is 30wt%, pulverize the corn stalks to obtain powdered corn stalks, mix the corn stalks powder and straw decomposing agent evenly in a mass ratio of 100:0.05, After 7 days of decomposing treatment, the fermented product of corn stalks was obtained.

[0031] Biochar is a solid product obtained by pyrolyzing corn stalks under 450°C oxygen-limited conditions; wood vinegar is a liquid product obtained by pyrolyzing corn stalks under 450°C oxygen-limited conditions.

[0032] The carbon-based fertilizer is prepared by mixing, pulverizing and granulating the above-mentioned biomass charcoal, nitrogen fertilizer, phosphorus ferti...

Embodiment 2

[0038] This embodiment provides a straw biomass seedling raising tray, the raw materials of which are as follows: 90 kg of fermented rice straw; 9 kg of water; 1 kg of wood vinegar, and 0.2 kg of charcoal-based fertilizer.

[0039] Wherein, the preparation method of the fermented product of rice straw is: drying the rice straw until its water content is 20wt%, pulverizing the rice straw powder, mixing the rice straw powder and a straw decomposing agent at a mass ratio of 100:0.02, and decomposing After 10 days of treatment, a fermented product of rice straw was obtained.

[0040] Biochar is a solid product obtained by pyrolyzing rice straw under 300°C oxygen-limited conditions; wood vinegar is a liquid product obtained by pyrolyzing rice straw under 300°C oxygen-limited conditions.

[0041]The carbon-based fertilizer is prepared by mixing, pulverizing and granulating the above-mentioned biomass charcoal, nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer accor...

Embodiment 3

[0047] This embodiment provides a straw biomass seedling raising tray, the raw materials of which are: 110 kg of fermented wheat straw; 12 kg of water; 1 kg of wood vinegar, and 0.2 kg of carbon-based fertilizer.

[0048] Wherein, the preparation method of the wheat straw fermented product is: dry the wheat straw until its water content is 40wt%, pulverize the wheat straw powder, mix the wheat straw powder and the straw decomposing agent according to the mass ratio of 100:0.08, After 12 days of decomposing treatment, the fermented wheat straw was obtained.

[0049] Biochar is a solid product obtained by pyrolyzing wheat straw under oxygen-limited conditions of 700°C; wood vinegar is a liquid product obtained by pyrolyzing wheat straw under oxygen-limited conditions of 600°C.

[0050] The carbon-based fertilizer is prepared by mixing, pulverizing and granulating the above-mentioned biomass charcoal, nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer according t...

Abstract

The invention relates to the technical field of soilless culture, and particularly discloses a straw biomass seedling raising tray and a preparation method thereof. The straw biomass seedling raising tray is prepared from a straw fermented material, water, wood vinegar liquid and carbon-based fertilizer according to the weight ratio of (90-110):(9-12):1:0.2; the components of the raw materials of the straw biomass seedling raising tray cooperate with one another, so that the straw biomass seedling raising tray is rich in organic matter and various elements required for the growth of crops, reasonable in EC value, moderate in pH value, high in water absorption and good in permeability, the aim of preparing and applying the fertilizer according to the growth law of plants is truly achieved, and the healthy growth of seedlings is ensured. By adopting the seedling raising tray, the average seedling age is 15-20 days, the effective length of white stalks is up to 5.7 cm, the growth speed of the seedlings is increased, the seedling emergence rate of the seedlings reaches 99%, the binding force of root systems is up to 34.5 N, underground parts of the seedlings have long main roots and many fibrous roots, seedlings turn green quickly after being transplanted, straw is thick and strong, and the disease resistance and lodging resistance are improved.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a straw biomass seedling raising tray and a preparation method thereof. Background technique [0002] Nutrient-based seedling cultivation is an important form of soilless seedling cultivation. It is an important technical link in the cultivation of vegetables, flowers, fruits, cotton, rice and other crops. It is an indispensable technical means to improve agricultural production efficiency, increase production and income. The conventional nutrient base is mainly made of soil, and the method of raising seedlings on the nutrient base is mainly through artificial soil mixing, fertilizer and sterilization, and then filling the plastic base to make the nutrient base, and then sowing and raising seedlings. This method has high cost, high labor intensity, low production efficiency, waste of resources and serious pollution. For areas with poor land resources, this method als...
