Environment-friendly slow release fertilizer for landscape greening seedlings

Abstract

The invention relates to environment-friendly slow release fertilizer for landscape greening seedlings. The environment-friendly slow release fertilizer for the landscape greening seedlings is characterized by being prepared from components in parts by weight as follows: 20-30 parts of sawdust powder, 15-20 parts of pine needle soil, 15-20 parts of alga mud, 10-15 parts of fermented cow dung, 5-8parts of carboxymethyl chitosan, 5-8 parts of humic acid, 5-8 parts of zeolite powder, 5-8 parts of traditional Chinese medicine dregs, 1-3 parts of potassium nitrate, 1-3 parts of boric acid, 2-4 parts of astaxanthin, 1-2 parts of plant fiber, 0.5-1 part of ferric citrate and 0.5-1 part of a plant growth regulator. The slow release fertilizer contains rich necessary nutrients needed by plants, has a long nutrient release period, can increase the fertilizer utilization rate and is suitable for the landscape greening seedlings.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an environment-friendly slow-release fertilizer for landscaping seedlings. Background technique [0002] Under the influence of the urbanization process, the planting of green seedlings has been paid more and more attention by people. During the growth of seedlings, fertilization is essential, and the quality of fertilizers directly affects the healthy growth of garden seedlings. Traditional seedling fertilizers are mainly farmyard manure and instant chemical fertilizers. Farmyard manure has low nutrient content, large application amount, high labor cost, and slow nutrient release rate, which cannot meet the growth and development needs of seedlings; instant chemical fertilizers often have single nutrients and easy nutrition. Washed by rain or fixed by the soil, the fertilizer utilization rate is not high, and it needs to be applied several times a year. Furthermore, the co...

Problems solved by technology

Traditional seedling fertilizers are mainly farmyard manure and instant chemical fertilizers. Farmyard manure has low nutrient content, large application amount, high labor cost, and slow nutrient release rate, which cannot meet the growth and development needs of seedlings; instant chemical fertilizers often have single nutrients and easy nutrition. Washed by rain or fixed by soil, resulting in low fertilizer use efficiency, and needs to be applied several times a year

Furthermore, the continuous application of instant chemical fertilizers will often cause soil acidification and compaction, causing secondary damage to the soil
