Embodiment 1

[0027] Refer to the method of Guo Shirong (2003) to measure the bulk density and porosity of the matrix. On the other hand, the matrix block is soaked and saturated, then drenched naturally, and dropped naturally from a height of 1m. The percentage of the weight of the remaining matrix after scattering and the weight of the complete matrix block is the forming rate .

[0028] The above experimental results are shown in Table 1. With the decrease of the amount of binder added, the bulk density of the molding matrix decreases, the air porosity increases, and the molding rate decreases gradually. T1-T5 treatment groups are divided according to different perlite content, the perlite content of T1 group is 10%, and the perlite content of T1-T5 treatment group is increased by 5%. In each binder ratio treatment group, with the increase of perlite content With the increase of , the bulk density showed a decreasing trend, the total porosity had no significant difference, and the moldin...

Embodiment 2

[0032] First measure the weight of the dried cultivation substrate, add an equal amount of water to each experimental group, according to the formula substrate water absorption (%)=(mass after substrate absorbs water-dry substrate quality) / dry substrate quality×100% can be Measure the water absorption of the matrix for each time period.

[0033] Further, different proportions of water-retaining agents were added to the adhesive 1:150 and 1:180 treatment groups, and they were divided into T1-T5 groups according to different proportions of water-retaining agents (groups T1, T2, T3, T4, and T5 corresponded to water-retaining agents at a ratio of 1:200 , 1:300, 1:400, 1:500, 1:600), the physical and chemical properties of the molding matrix were measured, as shown in Table 2, the 1:150 treatment group decreased with the addition of water-retaining agent, the ventilation pores and water absorption It showed a trend of first increasing and then decreasing, and there was no significa...

Embodiment 3

[0037] Soak and saturate the matrix block, weigh it every 1 hour with a 1 / 100 electronic balance, and calculate the water retention rate (R) according to the formula: R=(m′-m) / (m0-m)×100%, where , m' is the total amount of the matrix block (g), m is the dry weight of the matrix block (g), m0 is the mass of the matrix block after infiltration and saturation (g), and finally the water retention rate of each period is summarized and tabulated to obtain different ratios Trends in the effect of superplasticizers on the water retention of the molding matrix.

[0038] image 3 The effect of different proportions of water retaining agent on the water retention rate of the molding matrix in the binder 1:150 treatment group, Figure 4 For the influence of different ratios of water-retaining agents on the water-retaining rate of the molding matrix in the binder 1:180 treatment group, it is divided into T1, T3, and T5 groups according to different ratios of water-retaining agents (T1, T3...

Abstract

The invention provides a molded substrate and a preparing method thereof in order to solve the problems that in the prior art, operation is complicated, storage and transportation are not convenient, pollution is severe and roots are prone to damage during transplanting. The method includes the following steps of firstly, processing substrate raw materials, wherein the culture substrate is dried for use; secondly, mixing the dried substrate, perlite, an adhesive and a water retaining agent according to the product formula in volume ratio, wherein the volume of the dried substrate is 3600 cm<3>, the volume of the perlite is 10-30% the volume of the substrate, the volume ratio of the adhesive to the substrate is 1 to (120-180), and the volume ratio of the water retaining agent to the substrate is 1 to (200-600); thirdly, putting the materials in molds to be pressed, wherein the substrate, the perlite, the adhesive and the water retaining agent are evenly mixed in proportion, a proper volume of water is added to be stirred, and the materials are put in the molds of different specifications to be pressed into fixed shapes and then put in non-woven bags. The molded substrate is suitable for facility culture and family gardening, and is easy to operate, light in weight and capable of being transported for long distance.

Description

technical field [0001] The invention belongs to the field of cultivation, and relates to a molding matrix and a preparation method thereof. Background technique [0002] Traditional organic substrate soilless cultivation methods require cultivation containers such as sponge seedling blocks and rock wool planting mats. During the transplanting process, the substrate needs to be potted. The operation is cumbersome, and the roots are easily damaged during transplanting, resulting in unsatisfactory cultivation results. [0003] In recent years, seedling blocks have been popularized and applied on a large scale. They are mainly used for raising seedlings of vegetables such as cucumbers, tomatoes, and peppers. They are easy to operate and manage, have a high germination rate and roughly the same growth. At present, there are few related studies and reports on the molded substrate for vegetable cultivation. Due to the long time spent in vegetable cultivation, different water and fe...
