Embodiment 1

[0014] 1. EM bacterial liquid activation: Take 10.0ml EM stock solution, add 10.0g brown sugar, dilute 500 times with tap water (expose in the sun for 3h), add 0.5g NaCl respectively 2 and 0.5g FeCl 2 Prepare EM fermentation broth. Crush corn stalks, mix 80% corn stalks + 20% cow dung, mix the EM bacteria solution with the mixture at a ratio of 1.5:1, adjust the moisture content to 60%-70%, and the pH to 6.5-8.0, add A certain amount of urea is used to adjust the C / N ratio to 25:1-30:1, aerobic fermentation is performed at 25°C for 1 day, and then anaerobic fermentation is performed for 14 days to obtain fermented mixed feed.

[0015] 2. Adjust the water content of the fermented corn stalk and cow dung mixed feed to 50%-55%, and then put it into it - The larvae of the third instar white star beetle (the weight of each head is about 1.0g), put 250kg of the second to third instar early larvae of the white star beetle according to 1 ton of fermentation material, and raise them ...

Embodiment 2

[0018] 1. The insect powder obtained in Example 1 is used to raise laying hens. Every chicken replaces part of the commercial feed with 10-50g white star beetle larvae powder every day. The weight of a single egg has increased by 8-10g, and the egg production rate has increased by 2 %-4%, the egg yolk changes from light yellow to golden yellow, which improves the nutritional quality of eggs.

[0019] 2. Use the feces of the larvae of the white star beetle as an organic fertilizer for the production of leeks. The content of organic matter in the feces of beetle larvae is 34.1%, the content of nitrogen is 1.42%, the content of phosphorus pentoxide and potassium oxide is 1.31% and 1.33% respectively. When applying, choose to apply 1500- 3500kg, the color of harvested leeks is bright green, and the price can be 2-3 times that of ordinary leeks, which has high economic benefits.

Abstract

The invention relates to a method for conversion treatment of corn straw by potosia brevitarsis, which makes use of the saprophagous characteristic of potosia brevitarsis larvae, obtains larva bodies and larva manure with high protein by allowing potosia brevitarsis larvae to eat mixed fermentation feed of corn straw and cow dung, and realizing further conversion in larva abdomens, improves the value of corn straw and cow dung, reduces environment pollution caused by corn straw and cow dung, continuously upgrades the material flow of straw and livestock dung, and increases economic value.

Description

1. Technical field [0001] The invention relates to a method for transforming and treating corn stalks by utilizing the white star beetle, and belongs to the field of ecological cycle agriculture. 2. Technical Background [0002] my country is a big agricultural country, and my country's total straw production accounts for 1 / 5 of the world's total, ranking first in the world's total straw production. Corn is one of the main cultivated crops. It is expected that in recent years, my country's corn straw (core) will surpass rice straw and become the crop straw with the highest yield in my country. However, most of the corn straw resources have not been fully utilized at present. Many places use corn straw Straw is burned or abandoned as waste, which not only causes great waste of resources and huge economic losses, but also causes great environmental pollution. With the continuous expansion of the production scale of animal husbandry and the continuous improvement of the degree ...
