Embodiment 1

[0030] Implementation location: Nanhu Experimental Farm of Hubei Academy of Agricultural Sciences, Wuhan City, Hubei Province

[0031] The specific method of the present invention for producing organic fertilizer by using milk vetch and rice straw comprises the following steps: crush the milk vetch to a particle size of about 2 cm, dry it for one day, and control the water content at about 80%. Rice straw is sun-dried and crushed to powder. Fully mix milk vetch and rice straw according to the fresh weight ratio of 2.5:1, the water content after mixing is 58%, and the C / N ratio is 30:1. Before composting, add organic material decomposing agent (Hubei Jindi Agricultural Technology Co., Ltd., Microbial Fertilizer (2010) Linzi (1105) No.) according to 1.5% of the dry weight of the mixed material. Using the trough static composting process (the trough is 4.2m long, 1.8m wide, and 1m high, the bottom of the fermentation tank is equipped with an aeration pipe connected to a high-pre...

Embodiment 2

[0034] Implementation location: Nanhu Experimental Farm of Hubei Academy of Agricultural Sciences, Wuhan City, Hubei Province

[0035] The specific method for producing organic fertilizer by using milk vetch and rice straw in the present invention includes the following steps: the pretreatment of milk vetch and rice straw is the same as that in Example 1. Fully mix milk vetch and rice straw according to the fresh weight ratio of 4:1, the water content after mixing is 67%, and the C / N ratio is 39:1. Add organic material decomposing agent according to the dry weight of mixed material at 3%. Strip-stack composting, manual turning, turning once every 2d for the first 12d, turning once every 4d thereafter, and stopping turning after 20d.

[0036] The composting fermentation effect is: the temperature of the compost body rises to above 55°C after 12 hours, the temperature of the center of the compost body can reach up to 67°C, and the high temperature period (above 55°C) can be mai...

Embodiment 3

[0038] Implementation location: Nanhu Experimental Farm of Hubei Academy of Agricultural Sciences, Wuhan City, Hubei Province

[0039] The specific method of the present invention utilizing milk vetch and rice straw to produce organic fertilizer comprises the following steps: the pretreatment of milk vetch and rice straw is the same as in Example 1, the mixing ratio of milk vetch and rice straw, the pile body and the situation of turning over the pile are the same as in Example 2, and no organic fertilizer is added. Material decomposing agent.

[0040] The composting fermentation effect is: the temperature of the compost body rises to above 55°C after 12 hours, the temperature of the center of the compost body can reach up to 69°C, and the high temperature period (above 55°C) can be maintained for 8 days. The compost has been fermented for 23 days (including primary fermentation and secondary fermentation). Organic matter 69.8%, total nitrogen 2.4%, total phosphorus 0.8%, tot...

Abstract

The invention discloses an astragalus smicus / straw organic fertilizer and a preparation method thereof. The preparation method includes the steps of taking astragalus smicus at the full-blooming stage and crop straw (preferably rice straw) as raw materials, properly dewatering the astragalus smicus and then grinding the same into pieces with length ranging from 1cm to 5cm, uniformly mixing the ground pieces with chopped crop straw according to the proportion (2.0-4.5) : 1 by fresh weight, inoculating 0-4.0% of organic material decomposing agent by dry weight of mixture, and then carrying out aerobic composting and fermenting by conventional methods. The aerobic composting and fermenting process can be controlled within 25 days, the organic matter content of the fertilizer is equal to or higher than 70%, the NPK total nutrient content is equal to or higher than 5.5%, and the germination index is equal to or higher than 105.0%. Therefore, the organic fertilizer not only has functions as conventional organic fertilizers and but also can be used as a seedling substrate substituting for the 40% turf.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a commercial organic fertilizer produced by utilizing milk vetch and crop stalks and a preparation method thereof. Background technique [0002] Milk vetch is the most important green manure crop in the southern rice region of my country. It can not only significantly improve soil physical, chemical and biological fertility, but also is an important source of nectar and feed. In addition, milk vetch has a strong carbon absorption and nitrogen fixation function, which can reduce greenhouse gas emissions. Therefore, milk vetch has good economic, social and ecological benefits, and plays an important role in the modern agricultural production system with high yield, high quality and high efficiency. [0003] Milk vetch has a strong nitrogen fixation effect, and its main way of use is as a base fertilizer for early rice or mid-season rice. It is turned over to the field during the flowering ...
