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...

[0017] Example 1 Preparation of Mixed Culture Substrate for Raising Cashew Seedlings

[0018] Taking the cultivation of common cashew fruit raw bagged seedlings as an example, the operation process of the present invention is further described:

[0019] (1) Take the pond mud from the cultured fish pond, expose it to the sun for 2 days, after drying, smash it into 0.5-1cm 3 The granules are called pond mud, which is reserved for later use.

[0020] (2) In an open space, pile the dried grass with soil, leaves, and topsoil into a mound shape, with the weeds and leaves facing down, and the topsoil on top, and stack them alternately, and dig a hole at the bottom of the haystack as a Burn the crater, light it on fire, and then cover it with soil, let it burn slowly and retting for 3-4 days, and make fire soil for later use.

[0021] (3) According to the volume ratio, 3 parts of garden soil (according to the quality standard of DB 440300 / T 34-2008 landscaping planting soil), 2 par...

[0024] The cultivation of embodiment 2 cashew seedlings

[0025] (1) Pack the seedling-raising culture medium described in Example 1 into seedling-raising nutrition bags; plant the pretreated cashew nut seeds into the seedling-raising nutrition bags filled with the seedling culture culture medium, and then water them.

[0026] (2) Operate and manage according to the conventional seedling raising measures in production.

[0027] (3) In the process of growing cashew seedlings, the germination rate of the seedling culture medium described in Example 1 is increased by 8-10% compared with the original culture medium germination rate; the time of emergence from the nursery is 15-20 days earlier than the original culture medium; cashew bagged seedlings The colonization survival rate is 10-20% higher than that of the original culture medium.
