Problems solved by technology

However, due to the light texture and alkaline nature of shell powder, it is very dusty when applied in coastal sandstorm areas. Prolonged contact with shell powder during application may cause burns to the skin, and local concentration may be too high due to uneven application, which may cause burning of seeds and seedlings. In addition, shell powder is easy to lose after being applied to the soil, and the utilization rate is low, thus limiting product promotion

Embodiment 1

[0016] Weigh 85 kg of shell powder of 80 mesh and 15 kg of weathered coal of 80 mesh, and fully mix them evenly.

[0017] First, transport 50kg of the mixed material to the disc granulator for granulation. The speed of the granulator is controlled at 30-45r / min, and water is sprayed intermittently. The remaining material makes the core grow gradually, and finally reaches the desired particle (between 1.0-3.5mm); the control time of the granulation process is 15-25min. The granulated granular materials are directly dried in the sun or transported to a dryer at 80-100°C for drying, so that the moisture content is not higher than 2.5%. Then the dried material is sieved through a sieve, and finally the particle size of the finished product is controlled between 1.0-3.5mm, and the finished product rate can generally reach 80-85%. Unqualified products are crushed by a pulverizer and then re-granulated.

Embodiment 2

[0019] Weigh 80kg of 80-mesh shell powder and 20kg of 80-mesh weathered coal, and fully mix the two evenly.

[0020] First, transport 40kg of the mixed material to the disc granulator for granulation. The speed of the granulator is controlled at 30-45r / min, and water is sprayed intermittently. The remaining material makes the core grow gradually, and finally reaches the desired particle (between 1.0-3.5mm). The control time of the granulation process is 15-25min. The granulated granular materials are directly dried in the sun or transported to a dryer at 80-100°C for drying, so that the moisture content is not higher than 2.5%. Then the dried material is sieved through a sieve, and finally the particle size of the finished product is controlled between 1.0-3.5mm, and the finished product rate can generally reach 80-85%. Unqualified products are crushed by a pulverizer and then re-granulated.

Embodiment 3

[0022] Weigh 82 kg of shell powder of 80 mesh and 18 kg of weathered coal of 80 mesh, and fully mix them evenly.

[0023] First, transport 60kg of the mixed material to the disc granulator for granulation. The speed of the granulator is controlled at 30-45r / min, and water is sprayed intermittently. The remaining material makes the core grow gradually, and finally reaches the desired particle (between 1.0-3.5mm). The control time of the granulation process is 15-25min. The granulated granular materials are directly dried in the sun or transported to a dryer at 80-100°C for drying, so that the moisture content is not higher than 2.5%. Then the dried material is sieved through a sieve, and finally the particle size of the finished product is controlled between 1.0-3.5mm, and the finished product rate can generally reach 80-85%. Unqualified products are crushed by a pulverizer and then re-granulated.

Abstract

The inventive technique process of grainy calcium material for preventing and treating peanut blight primarily includes: adopting the shell powder and weathered coal as raw materials, machining into peanut blight prevention material through agglomeration granulation. The invention has innovative and reasonable design, which not only has simple process, easy implementing, but also has low cost of raw materials, product application convenience, remarkable peanut blight prevention effect, and capability of promoting high-efficient production pf peanut. In particular, the invention applies coastal oyster shell wastes for machining calcium materials for preventing and treating peanut blight, which not only reduces environmental pollution, but also promotes recycling of resources, has very significant economic, social and ecological benefits and greater promotional value.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizer and preparation production technology, and more specifically relates to a production technology of granular calcareous material for preventing and controlling peanut voids. Background technique [0002] The red-yellow soil area in southern my country is the main production area of ​​southern peanuts, with a planting area of ​​more than 1.1 million hectares. Peanuts are calcium-loving crops. Due to the impact of high temperature and rainy climate, soil acidification, coupled with the reduction of organic fertilizer application and the improper application of a large amount of physiological acidic fertilizer, the soil calcium is poor, which often leads to large areas of empty peanuts. This phenomenon occurs on coastal sandy land. Still serious. Peanut empty fields can reduce yields by 30% to 50% in light cases, or fail in severe cases, and many farmlands are even abandoned. At present, calc...
