Special organic fertilizer for torreya grandis and preparation method thereof

Abstract

The invention discloses a special organic fertilizer for torreya grandis. The organic fertilizer comprises the following raw materials in parts by weight: 30-50 parts of peat, 3-10 parts of tea seed cakes, 8-15 parts of peanut stalks, 3-8 parts of potassium fulvate and 1-3 parts of a biological matrix compound, wherein the biological matrix compound comprises aspergillus niger, candida tropicalisand high-temperature-resistant bacillus subtilis. The preparation method comprises the following steps: (1) crushing the tea seed cakes and the peanut stalks, then adding the peat, and adding a properamount of water until the content of moisture is adjusted to 50-55%; (2) adding the biological matrix compound into a mixture obtained in the step (1), carrying out aerobic fermentation for 3-5 daysunder an intermittent turning condition, and carrying out stacking and ageing for 5-7 days so as to obtain a fermented organic fertilizer for subsequent usage; (3) adding the potassium fulvate into the organic fertilizer prepared in the step (2), carrying out uniform stirring, and carrying out crushing and sieving; and (4) placing an organic fertilizer mixture prepared in the step (3) into a granulator, and carrying out drying until the content of the moisture is lower than 20% so as to obtain a finished product. The special organic fertilizer provided by the invention is rich in raw materialsource, feasible in technical route, good in application effect and significant in benefits.

Description

technical field [0001] The invention relates to the technical field of forestry planting, in particular to a special organic fertilizer for Chinese torreya and a preparation method thereof. Background technique [0002] Torreya torreya is an excellent variety of Torreya grandis in the genus Torreya (Taxaceac). Its main producing area is in Zhejiang, where there are about 21,000 mu of forests in Zhejiang Province, with an annual output of 1,200-1,500 tons. Torreya torreya female plants need to be pollinated and fertilized by male plants to bear fruit. It takes three years, or 29 months, for the first generation of torreya from flower bud differentiation to fruit harvest; it takes two years, or 17 months, to bear fruit. The female tree blooms in mid-to-late April, fertilizes and conceives fruit in June-July, matures in early-to-mid-September of the next year, and falls off a large number of young fruits for the first time in June-August of that year. Around April 20 of the ...
