Mixed cultivation substrate for raising seedlings of cashew nut and preparation method thereof

Abstract

The invention discloses a mixed cultivation substrate for raising seedlings of a cashew nut and a preparation process thereof. The seedling-raising mixed cultivation substrate of the cashew nut comprises the following components in parts by volume: 2-4 parts of garden soil, 1-3 parts of river sand or sand soil, 1-2 parts of coconut chaff or decaying sawdust, 1-3 parts of decaying cow dung, 2-3 parts of pond sludge, 1-2 parts of burnt soil and 3-5 parts of carbendazim or chlorothalonil. The prepared mixed cultivation substrate takes the garden soil, the river sand, the coconut chaff, the decaying cow dung, the pond sludge and the burnt soil as raw materials and the carbendazim is used for sterilizing; the components are environment-friendly, have no pollution and can improve the anti-disease (antibacterial) capability; by adding the river sand and the coconut chaff in the mixed cultivation substrate, the soil is not hardened after the seedlings are raised; the pond sludge, the decaying cow dung and the burnt soil in the mixed cultivation substrate have fertilizer effects; particularly, the pond sludge is an organic fertilizer formed by decomposing anaerobions under a water flooding condition after being mixed; and dry grains have more water-keeping and fertilizer-keeping functions.

Description

technical field [0001] The invention belongs to the field of seedling-raising mixed culture substrates of seedlings, and in particular relates to a cashew seedling-raised mixed culture substrate and a preparation process thereof. Background technique [0002] Cashew nuts (Anacardium occidentale L.) are native to northeastern Brazil and are a typical tropical evergreen tree fruit tree. They are one of the four famous nuts in the world. Cashew kernels contain 21.2% protein, 47% fat, 4.6-11.2% starch, 2.4-8.2% sugar, and vitamins A and B 1 , B 2 etc. It is used to make cashew nut chocolate, snacks and high-quality candied fruit, as well as fried and salted food. It is rich in nutrition and delicious in flavor, and is sold all over the world. By-products of cashew nuts include cashew shells, pears, etc. Cashew nut shell contains about 45% of cashew nut shell liquid, which contains 90% of cashew nut shell oleic acid and 10% of carduol. , synthetic rubber and submarine cable i...
