Problems solved by technology

However, as a short-term non-renewable resource, peat is limited in long-term use, and most of the domestic peat belongs to peat, which has a high degree of decomposition. Compared with foreign moss peat, its physical and chemical properties have certain differences. It is used for substrate cultivation. The effect is not very ideal
In addition, because peat basically does not contain nutrients, especially trace elements, it needs to be artificially added during the cultivation process, and improper control can easily lead to nutrient deficiency or poisoning

Abstract

The soil-less cultivating medium is produced with hickory shell as main material and through adding nitrogen to regulate C/N ratio to 25-30, adding fermenting bacteria seed via mixing, piling for fermentation of 50-60 days, sieving to obtain grains of size over 1 cm, drying to water content less than 30% and packing. The hickory shell has high organic matter content and high plant affinity, can strength the buffering property of medium and raise fertilizer keeping capacity, provide plant with rich potassium and trace elements and promote plant growth. What is most important is elimination the pollution of hickory shell.

Description

technical field [0001] The invention relates to a soilless cultivation substrate and a production method thereof, in particular to a soilless cultivation substrate produced from hickory shells which can partially replace peat and a production method thereof. technical background [0002] Substrate cultivation is playing an increasingly important role in vegetable and horticultural cultivation. Compared with soil cultivation, it has the advantages of saving water, fertilizer, and avoiding soil pollution. It can also avoid continuous cropping obstacles and adjust according to the needs of different plant production. Matrix physical and chemical properties. At present, the main cultivation medium is used after mixing peat, vermiculite and perlite in a certain proportion. However, as a short-term non-renewable resource, peat is limited in long-term use, and most of the domestic peat belongs to peat, which has a high degree of decomposition. Compared with foreign moss peat, its ...
