specific Embodiment approach 1

[0041] Specific embodiment 1: In this embodiment, a substrate plate for rice seedling raising without soil consists of 53-57 parts by weight of puffed plant stalks, 23-27 parts of fine grass carbon soil, 13-17 parts of coconut shell powder and 4- 5 servings of pulp.

[0042] In this embodiment, pulp is used as a binder, which has the advantage of being environmentally friendly and degradable. After drying, the fibers in the pulp ensure the strength of the rice straw matrix board. After watering during use, the fiber strength of the pulp is basically lost, making the matrix board soft and useful for seed sowing and root growth and breathing.

[0043] Fine grass carbon soil and puffed straw are rich in nutrients, of which the nutrients account for about 55% of the total amount of materials.

[0044] In this embodiment, the rice straw substrate board for soilless seedling raising of rice is green and environment-friendly, and the humus content is more than 40%.

specific Embodiment approach 2

[0045] Embodiment 2: In this embodiment, a soilless rice seedling raising straw matrix board is made of 55 parts by weight of puffed plant straw, 25 parts of fine grass carbon soil, 15 parts of coconut shell powder and 5 parts of paper pulp.

specific Embodiment approach 3

[0046] Specific embodiment three: In this embodiment, a substrate plate for soilless seedling raising of rice is prepared according to the following steps:

[0047] In the first step, the plant straw is firstly cut to 0.5-0.8 mm, and then crushed to 30-50 mesh for puffing and granulation. The puffing temperature is 300-400 degrees, and the granulation diameter is 8-10 mm.

[0048] Step 2: In this embodiment, the rice soilless seedling raising crop stalk substrate board is made of 53 parts by weight of puffed plant stalks, 23 parts of fine grass carbon soil, 13 parts of coconut shell powder and 4 parts of paper pulp.

[0049] The third step: Mix the puffed plant straw particles, fine peat, coconut shell powder and other materials with clean water and mix them with a beater to grind them to a fineness of 80-100 mesh, and adjust the pH to 4.5-5 with concentrated sulfuric acid. The amount of water determines the thickness of the board, add water in an appropriate amount. The thic...

Abstract

The invention relates to a soilless rice nursery straw substrate and a preparation method thereof. The soilless rice nursery straw substrate is characterized by being prepared from, by weight, 53-57 parts of puffing plant straw, 23-27 parts of fine soddy soil, 13-17 parts of coconut shell powder and 4-5 parts of paper pulp. The substrate is used for rice nursery, organic matter straw and other agricultural waste are adopted as main raw materials of the straw substrate, exploitation of the non-renewable resource soil is saved, the environment is protected against damage, and the crop straw waste resource is utilized again, the temperature of a seedbed base is increased, the water retention is good, and the rice seedling planting percent and quality are improved.

Description

technical field [0001] The invention relates to a rice seedling raising technology, in particular to a rice straw substrate board for soilless seedling raising using crop straw and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and agricultural economy occupies a major position in the national economy. Since the reform and opening up, the state has invested a lot of money and material resources to ensure food security, engaged in the construction of farmland water conservancy and the development of paddy fields, and supported farmers to grow rice. Significant improvements have been made in rice area, rice variety improvement, and rice planting technology, which have played an important role in ensuring my country's food security. So far, my country's rice planting technology and economic benefits per unit area still need to be further improved. In particular, the seedling raising technology in the three links of rice...
