Organic matrix for cultivating vegetable and preparation method thereof

Abstract

The invention discloses an organic matrix for cultivating a vegetable and a preparation method thereof. Raw materials of the matrix comprise the following components in percentage by weight: 8 to 15 percent of silkworm excrement, 30 to 45 percent of modified palm fiber, 5 to 10 percent of straw powder, 2 to 5 percent of typha orientalis presl root, 3 to 8 percent of bean dreg, 0.01 to 0.05 percent of microorganism, 10 to 15 percent of plant ash and the balance of water. In the matrix, the modified palm fiber, the straw powder and the typha orientalis presl root have plentiful cellulose, and can be used for providing a favorable growth condition for the growth of a root system of the vegetable; the typha orientalis presl root has a quite good fixation effect on heavy metals, and can be used for preventing the heavy metals in the straw powder and the plant ash from being abundantly absorbed by the vegetable to be accordingly eaten by a human body; after being modified, a palm fiber not only contains abundant organic matters and oily substances to provide nutrients for the growth of the vegetable, but also has quite good slow release effects on absorbed phosphorus fertilizer and nitrogen fertilizer, and can be used for a long time; the matrix does not need to be frequently replaced. The raw materials of the organic matrix comprise the palm fiber, straw, the typha orientalis presl root, the bean dreg and the silkworm excrement, which are all waste after being utilized by an animal and plants, and are subjected to secondary utilization; waste substances are changed into valuable substances; the requirement on an environment is low; the popularization is easy.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to an organic substrate for vegetable cultivation and a preparation method thereof. Background technique [0002] Organic substrate cultivation refers to the use of organic matter such as crop straw, mushroom dregs, peat, sawdust, livestock and poultry manure, etc., after fermentation or high temperature treatment, mixed in a certain proportion to form a relatively stable and buffering full-nutrient cultivation substrate raw material. In order to improve the physical and chemical properties of the cultivation substrate, river sand, cinder, vermiculite, perlite and other inorganic substances can be mixed with it in a certain proportion to form an organic and inorganic cultivation substrate. Since the 1990s, my country's facility agriculture has developed rapidly, and now it has exceeded 2.6 million hectares, becoming a pillar industry in my country's rural areas. The rapid...
