Problems solved by technology

[0009] Today, when resource conservation and sustainable development are vigorously advocated, the research on the reuse of agricultural and forestry wastes in my country is still in its infancy. The traditional methods of disposal of agricultural and forestry wastes in my country are mainly landfill or incineration. Although most of the agricultural and forestry wastes have been removed, However, these methods have brought environmental pollution and waste of resources. Excessive removal of agricultural and forestry wastes will also cause serious soil acidity or alkalinity, lower organic matter and nutrient content, easy compaction, poor ventilation and other problems, destroying the soil ecological cycle. Decrease soil fertility year by year

Embodiment 1

[0082] 1. Preparation of matrix conditioner

[0083] 1-1) Prepare the raw materials according to the following weight parts (Kg)

[0084] Seaweed residue 30

[0085] Coir 40

[0086] Phosphocalcite 15

[0087] 1-2) The seaweed residue, coconut shell fiber, and calcium phosphate soil are respectively pulverized into seaweed residue powder, coconut shell fiber powder, and calcium phosphate soil powder. The particle size of the seaweed residue powder is 2~5mm; the particles of coconut shell fiber powder The diameter is 3.0~5.0cm; the particle diameter of phosphocalcite powder is 2.5~5.0mm, spare;

[0088] 1-3) Mixing seaweed residue powder, coconut shell fiber powder and phosphocalcite powder evenly to obtain a cultivation substrate conditioner.

[0089] The cultivation substrate conditioner of the present invention is mainly aimed at the phenomenon that the pH value of the cultivation substrate is too high or too low, and the EC value is too high. It can effectively adjust the pH value of ...

Embodiment 2

[0112] Except for the selection of soil for plant cultivation substrate in step 2-1), the weight ratio of soil to plant cultivation substrate conditioner is 100:30, and the weight ratio of soil to fungicide is 10000:0.35; step 2-2) adds water mixture The water content is 62%, and the rest is the same as in Example 1. The performance measurement results of the prepared composite plant cultivation substrate are shown in Tables 1 and 2.

Embodiment 3

[0114] Except for the selection of waste compost substrate for plant cultivation substrate in step 2-1), the weight ratio of waste compost substrate and plant cultivation substrate conditioner is 100:35, and the weight ratio of compost substrate and fungicide is 10000:1.35; step 2-2) Except that the water content of the water-added mixture is 65%, the rest is the same as in Example 1. Among them, the waste compost substrate is prepared as follows:

[0115] 2-1-1) Use a pulverizer (Beijing Zhongyi Shenlong Machinery Co., Ltd.) to pulverize the branches and trunks of garden waste (pruned branches and trunks of willow, locust, poplar, etc.) into particles with a particle size of ≤ 1 cm. For waste particles, Kjeldahl method is used to determine the nitrogen content of agricultural and forestry waste particles; potassium dichromate volumetric method-external heating method is used to determine the organic carbon content in agricultural and forestry waste particles;

[0116] 2-1-2) Add u...

Abstract

The invention discloses a plant culture substrate conditioner and a preparation method thereof and a method for using the conditioner for preparing a composite culture substrate. The substrate conditioner comprises alga residues, coconut fibers and phosphorite. The composite culture substrate prepared through the substrate conditioner is balanced in nutrition, high in nutrient content, stable in physical property and reasonable in nutritional structure. The prepared composite culture substrate has good cation exchangeability and adsorbability, can adsorb a large amount of salt with a buffer effect, has a buffer effect and can obstruct rapid changes of pH values and EC values, the acid-base environment of the substrate is regulated, the effect that nutrients are slowly released is achieved, breathing and growth of plant root systems are promoted, absorption of the nutrients by the root systems is promoted, plant growth requirements are met, the survival rate of plant culture is raised, and the appreciation effect is improved.

Description

Technical field [0001] The invention relates to a conditioner for plant cultivation nutrient substrate, a method for preparing a nutrient substrate and a nutrient substrate, in particular to a nutrient substrate conditioner for soilless cultivation of plants, a method for preparing an application substrate using the conditioner, and a prepared nutrient substrate. Background technique [0002] Substrate is the basis of soilless substrate cultivation, and substrate cultivation is the largest facility cultivation method in soilless cultivation. It fixes the roots of plants in organic or inorganic substrates, and supplies nutrients to plants through drip irrigation or trickle irrigation. At present, as a commonly used soilless culture substrate material in my country, peat is widely used in flower cultivation, factory seedling cultivation of vegetables and seedlings, roof greening, and soil improvement. [0003] Peat is also called peat, peat soil, or peat. The coal with the lowest de...
