Embodiment 1

[0041] The invention discloses a method for making biological fertilizer, the steps are as follows:

[0042] 1) Pre-treat chestnut leaves. The pre-treatment steps are: dig a ditch with a depth of 10 cm under the chestnut tree, fill the ditch with chestnut leaves, and also fill the ditch with weeds and chestnut canopy. Cubic chestnut leaves (or containing chestnut leaf debris) are sprayed with 1000ml of liquid microbial fertilizer, and then the surface is covered with 2cm of soil.

[0043] 2) Mix the fermented chestnut leaves, livestock and poultry excrement and peat soil to make matrix fertilizer; urea is also added to the matrix fertilizer, and the weight ratio of chestnut leaves, livestock and poultry excrement to peat soil is 6:4: 3; wherein the excrement of livestock and poultry comprises dry cow dung and wet chicken manure, wherein dry cow dung accounts for 20% of the dry weight of excrement of livestock and poultry; the water content of the wet chicken manure is 60%; dur...

Embodiment 2

[0050] The invention discloses a method for making biological fertilizer, the steps are as follows:

[0051] 1) Pre-treat chestnut leaves. The pre-treatment steps are: dig a ditch with a depth of 10 cm under the chestnut tree, fill the ditch with chestnut leaves, and also fill the ditch with weeds and chestnut canopy. Cubic chestnut leaves (or containing chestnut leaf debris) are sprayed with 1000ml of liquid microbial fertilizer, and then the surface is covered with 2cm of soil;

[0052] 2) Mix the fermented chestnut leaves, livestock and poultry excrement and peat soil to make matrix fertilizer; urea is also added to the matrix fertilizer, and the weight ratio of chestnut leaves, livestock and poultry excrement to peat soil is 6:4: 3; wherein the excrement of livestock and poultry comprises dry cow dung and wet chicken manure, wherein dry cow dung accounts for 30% of the dry weight of excrement of livestock and poultry; the water content of the wet chicken manure is 80%; dur...

Embodiment 3

[0058] The invention discloses a method for making biological fertilizer, the steps are as follows:

[0059] 1) Pre-treat chestnut leaves. The pre-treatment steps are: dig a ditch with a depth of 10 cm under the chestnut tree, fill the ditch with chestnut leaves, and also fill the ditch with weeds and chestnut canopy. Cubic chestnut leaves (or containing chestnut leaf debris) are sprayed with 1000ml of liquid microbial fertilizer, and then the surface is covered with 2cm of soil;

[0060] 2) Mix the fermented chestnut leaves, livestock and poultry excrement and peat soil to make matrix fertilizer; urea is also added to the matrix fertilizer, and the weight ratio of chestnut leaves, livestock and poultry excrement to peat soil is 6:4: 3; wherein the excrement of livestock and poultry comprises dry cow dung and wet chicken manure, wherein dry cow dung accounts for 25% of the dry weight of excrement of livestock and poultry; the water content of the wet chicken manure is 70%; dur...

Abstract

The invention discloses a biofertilizer which is prepared from Chinese chestnut leaves by fermentation. The biofertilizer contains 200-300 million / g of Bacillus subtilis, 6-10 million / g of Paenibacillus kribbensis, 55%-80% of organic matter (dry base), 2%-3% of N (dry base), 3%-4% of P2O5 (dry base) and 2%-3% of K2O (dry base). The defect that the conventional organic fertilizer prepared from the Chinese chestnut leaves has insufficient fertility and cannot be used for cultivating Chinese chestnut trees is overcome.

Description

technical field [0001] The invention belongs to the technical field of microorganisms and fermentation, and in particular relates to a biological fertilizer and a preparation method thereof. Background technique [0002] Chestnut cultivation area in Qianxi, China is up to 750,000 mu. The site conditions are hilly and mountainous, and the ability to preserve fertilizer, water and soil is poor, resulting in low yield and quality of chestnut, and poor efficiency. Each mu of chestnut produces 315-333 kg of fallen leaves and fallen leaves, and the annual output of fallen leaves reaches 236,250-249,750 tons. Research has determined that nitrogen, phosphorus, potassium, magnesium, copper, zinc, iron, manganese, and boron are 13.6g, 1.6g, 4.1g, 6.1mg, 27mg, 289mg, 541mg, and 23.2mg per kilogram of chestnut leaves in the defoliation stage. And it contains 60.3g of organic matter, which is a good nutrient resource, rich in resources, renewable and sustainable. [0003] The Chinese i...
