Embodiment 1

[0042] The making of embodiment 1 Meretrix meretrix cultured fertilizer bait

[0043] (1) get chicken manure coarse raw material 10Kg, adjust moisture content to about 20%, obtain chicken manure fine raw material through rough selection and sieving;

[0044] (2) Inoculate chicken manure fine raw materials with EM complex bacteria for fermentation (fermentation temperature is 60° C., fermentation time is 20-30 days). During the fermentation process, chicken manure is fully stirred 9 times. After dehydration, bio-fermentation chicken manure is obtained.

[0045] (3) Take 1340g of the above-mentioned bio-fermented chicken manure and add urea 100g, CaP 2 O 4 400g, zeolite powder 100g, NaNO 3 40g, KH 2 PO 4 10g, Na 2 SiO 3 12g is stirred and mixed to obtain the fertilizer bait for clam cultivation.

[0046] The percentage by weight of each component of the fertilizer and bait for clam culture obtained above is: 66.9% of biologically fermented chicken manure; 5% of urea;...

Embodiment 2

[0047] The making of the fertilizer bait of embodiment 2 Meretrix meretrix culture

[0048] Get embodiment 1 and make biofermentation chicken manure 1240g add urea 80g, CaP 2 O 4 500g, zeolite powder 100g, NaNO 3 50g, KH 2 PO 4 16g, Na 2 SiO 3 10g is stirred and mixed to obtain the fertilizer bait for clam cultivation.

[0049] The percentage by weight of each component of the fertilized bait for clam cultivation is as follows: 62.2% of biologically fermented chicken manure; 4% of urea; 4% of CaP 2 O 4 25%; Zeolite powder 5%; NaNO 3 2.5%; KH 2 PO 4 0.8%;Na 2 SiO 3 0.5%.

Embodiment 3

[0050] Embodiment 3 Meretrix meretrix cultivates Monocellular algae with fertilizer bait

[0051] 1 Algal species and cultivation

[0052] 1.1 Source of algal species

[0053] Isochrysis 3011 was provided by the School of Life Science and Technology of Shanghai Fisheries University, and Chaetoceros and Chlorella were provided by the School of Life Sciences of Ningbo University.

[0054] 1.2 Preparation of culture medium

[0055] The formula of the culture medium: FeC 6 h 5 O 7 5g, EDTA-2Na 25g, KNO 3 100g, KH 2 PO 4 10g, Na 2 SiO 3 9H 2 O 15g, V B1 , V B12 1 injection, 1000ml distilled water. When preparing the nutrient solution, first put ferric citrate and EDTA-2Na into the Erlenmeyer flask to heat and dissolve, then put in other nutrient salt components, then sterilize under high pressure for 15 minutes, and then add V after cooling B1 , V B12 Injections are finally placed in a low-temperature refrigerator for future use.

Abstract

The present invention relates to fertilizer made with fermented chicken dung, and is especially fertilizer bait for cultivating clam. The fertilizer bait consists of fermented chicken dung 50-80 weight portions, urea 3-7 weight portions, CaP2O4 10-30 weight portions, zeolite powder 2-8 weight portions, NaNO3 1-3 weight portions, KH2PO4 0.2-1.0 weight portion and Na2SiO3 0.4-1.0 weight portion. Cultivating clam with the fertilizer bait can result in raised clam yield, shortened cultivation period, no water pollution and less diseases.

Description

(1) Technical field [0001] The invention relates to a fertilizer made from fermented chicken manure, in particular to a fertilizer bait for cultivating clams. (2) Background technology [0002] Clam [Meretrix meretrix (Linnaeus)] is not only delicious in meat (known as the freshest in the world), rich in nutrition, but also has high dietary and medicinal value. It is one of the main aquatic products exported by our country and our city to earn foreign exchange. At present, the supply of high-quality Meretrix meretrix clams is in short supply in the international market, and the domestic sales volume is also increasing day by day. The market potential is huge. Japan alone has an annual sales volume of more than 60,000 tons, 95% of which are imported from abroad (mainly China), and the EU market has even greater potential. [0003] Clam farming has a long history in my country, mainly distributed in Jiangsu, Shandong, Dandong, Guangxi and other places. Although clam pond cul...
