Preparation method of nutrient soil containing dry pine needles

Abstract

The invention provides a preparation method of nutrient soil containing dry pine needles. The preparation method comprises: 1, mixing the following raw materials by weight: 10-20 parts of coconut shell fiber powder, 25-30 parts of dry pine needles, 20-25 parts of garden soil, 1-2 parts of traditional Chinese medicine residue and 10-20 parts of a fully-composted organic fertilizer to obtain a matrix mixture; 2, spraying the surface of the matrix mixture with a potassium permanganate solution with a mass fraction of 0.3%, uniformly mixing, spreading on the ground, maintaining the thickness at below 1 cm, and drying in the sun for 1-3 days; and 3, adding 10-15 g of a chlorine dioxide disinfectant to per cubic meter of the matrix mixture, and uniformly mixing to obtain the nutrient matrix. According to the present invention, the nutrient soil containing dry pine needles can provide nutrition for the eggplant seedling raising process.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a preparation method of nutrient soil containing dried pine needles. Background technique [0002] Eggplants are cultivated in early spring in large arch sheds, because most of them are planted in early March, so the seedling cultivation period starts from the end of December to the beginning of January, about two months. At this time, it is the cold winter period, the temperature is low, and the growth period of eggplant seedlings is relatively prolonged. At present, the cost of commercialized eggplant seedling substrates is relatively high, and peat-based commercial substrates are mostly used. In order to ensure the growth of eggplant seedlings, it is necessary to add fertilizers to the seedling cultivation substrates or spray fertilizers with water during the growth period of eggplant seedlings to ensure the growth of eggplant seedlings. Seedling growth, but this not onl...

Problems solved by technology

At present, the cost of commercialized eggplant seedling substrates is relatively high, and peat-based commercial substrates are mostly used. In order to ensure the growth of eggplant seedlings, it is necessary to add fertilizers to the seedling cultivation substrates or spray fertilizers with water during the growth period of eggplant seedlings to ensure the growth of eggplant seedlings. seedling growth, but this not only increases the cost and is easy to make the eggplant seedlings grow excessively, which is not conducive to the cultivation of strong seedlings, but also has many disadvantages to the growth of eggplant seedlings
