Culture medium for longan and preparation method of culture medium

Abstract

The invention discloses a culture medium for longan. The culture medium is prepared from components in parts by weight as follows: 80-100 parts of soil in a field where taros are planted, 20-30 parts of urea, 10-18 parts of silicon oxide, 5-10 parts of potassium chloride, 7-9 parts of calcium superphosphate, 8-12 parts of amino acid, 10-15 parts of rice hull powder, 10-20 parts of pine sawdust, 3-5 parts of plant ash, 30-35 parts of sesame straw, 28-30 parts of sweet potato straw, 15-20 parts of sugarcane tip debris, 10-12 parts of pagoda tree leaves, 8-12 parts of edible mushroom residues, 8-12 parts of composted pig and cow manure, 10-20 parts of bean dregs and 0.5-0.7 parts of microelements. The culture medium is mainly prepared from components including urea, silicon oxide, potassium chloride, calcium superphosphate, amino acid and the like, can sufficiently supplement nitrogen, phosphorus, potassium, magnesium, zinc and other nutritional ingredients essential to longan trees in growth and can further improve soil, and improvement of the soil further allows the longan trees to absorb the nutritional ingredients better.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a longan cultivation substrate and a preparation method thereof.

Problems solved by technology

[0003] At present, the cultivation medium of longan is mostly determined by farmers based on experience, and the selection of substrate raw materials, application amount and application method are not properly selected, and the selected substrate raw materials are mostly conventional nitrogen fertilizers, phosphorus fertilizers, etc., with single ingredients and no obvious effect , causing the cultivated longan saplings to have insufficient cold resistance and sturdiness, which is not conducive to cultivation and grafting, thus increasing the investment risk
