Preparation method for a plantation fertilizer special for Chinese yews

Abstract

The invention relates to a preparation method for a plantation fertilizer special for Chinese yews. The method comprises the following steps, firstly, tung oil cakes are added in a pulverizer, pulverized and added with water, and the water content is kept in 60-65%; secondly, by weight, 0.15-0.2% of trichoderma viride, 0.15-0.2% of aspergillus oryzae, 0.05-0.1% of bacillus subtilis and 0.05-0.1%of rhodopseudomonas palustris are added in the above tung oil cake residues, the mixture is mixed uniformly and subjected to compost primary fermentation, and the fermentation temperature is controlled at 60-65 DEG C; thirdly, when the primary fermentation temperature is lowered to 40 DEG C, by weight, 0.05-0.1% of azotobacter chroococcum, 0.05-0.1% of bacillus megaterium and 0.05-0.1% of bacillus mucilaginosus are added in the compost and the mixture is subjected to secondary fermentation, and the fermentation temperature is kept under 50 DEG C; fourthly, by weight, 85-95% of the fermented organic fertilizer and 5-15% of the potassium sulfate composite fertilizer are mixed uniformly. The provided plantation fertilizer special for Chinese yews can promote growth of Chinese yews and does not pollute the environment.

Description

technical field [0001] The invention relates to a preparation method of an organic fertilizer, in particular to a preparation method of a special planting fertilizer for yew. Background technique [0002] Yew branches and leaves are used to treat leukemia, nephritis, diabetes and polycystic kidney disease. It is recognized as an endangered natural and rare anti-cancer plant in the world. It also has diuretic swelling, treatment of kidney disease, diabetes, nephritis edema, dysuria, gonorrhea and other effects. Compared with other countries in the world, my country's yew resources account for more than half, but judging from the demand for paclitaxel in the world, it is still far from enough. The strong market demand still brings long-term challenges to the survival of endangered yews. and persistent stress. [0003] However, the main root of yew is not obvious and the lateral roots are developed. Due to the slow growth rate and poor regeneration ability of yew under natural...
