Embodiment 1

[0012] Embodiment 1, adopt artificial substrate Ⅰ to carry out hole tray tomato seedling cultivation

[0013] (1) Preparation of artificial matrix I: the components and their mass percentages are: 10% biogas residue, 40% peat, 40% vermiculite, and 10% perlite; mix the above-mentioned components uniformly in corresponding proportions to obtain this product. In the artificial substrate of the invention, the biogas residue fermentation raw material is chicken manure.

[0014] (2) Use artificial substrate Ⅰ to cultivate tomato seedlings in plug trays. The specific cultivation method is as follows: 2 trays for each treatment, tomato seeds soaked in warm soup to accelerate germination, sow in 72-hole trays, and place them in a greenhouse to grow seedlings. The water supply index is to maintain the substrate. The relative moisture content is around 60%. After 28 days of seedling cultivation, the growth index listed in Table 1 was measured, and the specific cultivation conditions wer...

Embodiment 2

[0021] Embodiment 2, adopting artificial substrate II to carry out hole tray tomato seedling cultivation

[0022] (1) Preparation of artificial matrix II: the components and their mass percentages are: 20% biogas residue, 40% peat, 30% vermiculite, and 10% perlite; mix the above-mentioned components in corresponding proportions to obtain this product. In the artificial substrate of the invention, the biogas residue fermentation raw material is pig manure.

[0023] (2) Use artificial substrate II to cultivate tomato seedlings in plug trays. The specific cultivation method is as follows: 2 trays for each treatment, after soaking tomato seeds in warm soup to accelerate germination, sow them in 72-hole trays, and place them in a greenhouse to grow seedlings. The water supply index is to maintain the substrate. The relative moisture content is around 60%. Carry out the mensuration of growth index listed in table 3 after raising seedlings 28 days, cultivate specific situation as sh...

Abstract

The invention discloses an artificial substratum for hole-tray tomato seedling cultivation, which belongs to the technical field of soilless culture. The artificial substratum takes biogas dregs as a fertilizer source, and the fermentation raw material of the biogas dregs is chicken manure or pig manure; when the fermentation raw material of the biogas dregs is the chicken manure, the artificial substratum comprises the following components in mass percentage: 9 to 11 percent of biogas dregs, 39 to 41 percent of grass carbon, 39 to 41 percent of vermiculite and 9 to 11 percent of pearlite; and when the fermentation raw material of the biogas dregs is the pig manure, the artificial substratum comprises the following components in mass percentage: 19 to 21 percent of biogas dregs, 39 to 41 percent of grass carbon, 29 to 31 percent of vermiculite and 9 to 11 percent of pearlite. The biogas dregs in the formula of the artificial substratum of the invention can improve a growth indicator of tomato seedlings and reduce the accumulation of nitride in the plant bodies to a certain degree, so that the equality is improved; and the use of the biogas dregs reduces the used amount of the grass carbon, so that the production cost of the artificial substratum and the seedlings is reduced.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to an artificial substrate for cultivating tomato seedlings using biogas residues as a fertilizer source. Background technique [0002] In recent years, industrialized rapid seedling cultivation technology has become the key technology for large-scale vegetable production, and the pollution-free, safe and high-quality seedling production of vegetables has become an important guarantee for the production of pollution-free vegetables. The key of industrial seedling raising is exactly the artificial substrate technology, wherein, the organic ecological type soilless culture technology (publication number is CN01127441.7) refers to not using natural soil, but using substrate; not using traditional nutrient solution to irrigate plant roots, but using organic solid It is a soilless cultivation technique that uses fertilizer and directly uses clean water to irrigat...
