Embodiment 1

[0018] A special fertilizer for milk vetch cultivation consists of the following raw materials in parts by weight: 92 kg of urea, 50 kg of ammonium sulfate, 430 kg of monoammonium phosphate, 265 kg of potassium chloride, 30 kg of borax, 1 kg of ammonium molybdate, and 60 kg of zeolite powder kg, attapulgite powder 61 kg;

[0019] The above raw materials are uniformly mixed, crushed, granulated and dried to obtain granulated milk vetch special fertilizer. Zeolite powder uses agricultural zeolite above 100 mesh; then sieve the granular milk vetch special fertilizer, pass through a sieve with a diameter of 4.75mm and a sieve with a diameter of 1.00mm, and then pass through a coating film, and then use a polymer surface active Sodium dodecylbenzene sulfonate is dissolved in mineral oil to coat granular fertilizers to obtain milk vetch special fertilizer products;

[0020] The contents of nitrogen, phosphorus, potassium, boron and molybdenum in the milk vetch special fertilizer ar...

Embodiment 2

[0022] A milk vetch special formula fertilizer is composed of the following raw materials in parts by weight: 80 kg of urea, 60 kg of ammonium sulfate, 450 kg of monoammonium phosphate, 250 kg of potassium chloride, 35 kg of borax, 1 kg of ammonium molybdate, and 60 kg of zeolite powder 64 kilograms of kilograms, attapulgite powder; Preparation method is with embodiment 1;

[0023] The above raw materials are mixed evenly, crushed, granulated and dried, and then the polymer surface active substance alkyl polyoxyethylene ether is dissolved in mineral oil to coat the granule fertilizer to obtain milk vetch special fertilizer products;

[0024] The contents of nitrogen, phosphorus, potassium, boron and molybdenum in milk vetch special fertilizer are 9.9%, 19.8%, 15.0%, 0.38% and 0.05% respectively. It is applied when planting milk vetch, and 15 kg per mu is used as base fertilizer. It can also be topdressed at the seedling stage of milk vetch after rice harvest. After the specia...

Embodiment 3

[0026] A milk vetch special formula fertilizer is composed of the following raw materials in parts by weight: 110 kg of urea, 40 kg of ammonium sulfate, 410 kg of monoammonium phosphate, 275 kg of potassium chloride, 25 kg of borax, 1 kg of ammonium molybdate, and 60 kg of zeolite powder 79 kilograms of kilograms, attapulgite powder; Preparation method is with embodiment 1;

[0027] Mix the above raw materials evenly, crush, granulate and dry, and then dissolve the polymer surface active substance aryl polyoxyethylene ether into mineral oil to coat the granular fertilizer to obtain milk vetch special fertilizer products;

[0028] The contents of nitrogen, phosphorus, potassium, boron and molybdenum in milk vetch special fertilizer are 10.4%, 18.0%, 16.5%, 0.28% and 0.05% respectively. It is applied when planting milk vetch, and 15 kg per mu is used as base fertilizer. It can also be topdressed at the seedling stage of milk vetch after rice harvest. After the special fertilize...

Abstract

The invention relates to a special fertilizer for culturing Chinese clover. The special fertilizer for culturing Chinese clover comprises the following raw materials by weight: 80-110 Kg of urea, 40-60 Kg of ammonium sulfate, 410-450 Kg of ammonium diacid phosphate, 250-275 Kg of potassium chloride, 25-35 Kg of borax, 1 Kg of ammonium molybdate, 60 Kg of zeolite powder, 61-79 Kg of attapulgite clay powder; the raw materials are mixed uniformly, crushed, granulated and dried to obtain the special particle fertilizer for Chinese clover; the zeolite powder adopts agricultural zeolite of 100 meshes above; and the special particle fertilizer for Chinese clover is screened sequentially by a screen with a diameter of 4.75mm and a screen with a diameter of 1.00mm, and then is coated to obtain the special fertilizer for culturing Chinese clover. After the special fertilizer for culturing Chinese clover is applied to Chinese clover, Chinese clover grows vigorously and healthily and the root nodules are increased, and the fresh grass yield is increased by more than 25% per acre.

Description

technical field [0001] The invention belongs to the technical field of fertilizers for plant cultivation, and in particular relates to a fertilizer for milk vetch cultivation. Background technique [0002] Milk vetch is the main winter green manure and high-quality feed in the southern rice region of my country. It has the functions of enriching the nutrients in the soil, improving the physical properties of the soil, and promoting the development of animal husbandry. The traditional planting of milk vetch adopts no fertilization or application of phosphorus-containing superphosphate or ordinary three-element compound fertilizer. On the one hand, lack of fertilizer in milk vetch causes poor growth, and on the other hand, nutrient imbalance (such as more nitrogen, less phosphorus and potassium, No trace elements such as boron and molybdenum) cause fertilizer waste. Milk vetch is a plant that likes phosphorus, potassium, boron, and molybdenum. Especially in terms of nodulatio...
