preparation example Construction

[0023] Correspondingly, the present invention also provides a preparation method of a special soil conditioner for yam planting, comprising the following steps: step a) crushing 400-600 parts by weight of dry straw, soaking it in water in which 0.5-3 parts by weight of straw decomposing agent has been dissolved Wet; step b) Put the processed straw powder, 700-1300 parts by weight of low-rank coal, 300-800 parts by weight of human and animal manure, and 5-20 parts by weight of EM bacteria into the fermentation tank, stir and mix them and then ferment in a sealed manner at a temperature of 40 -65°C, the fermentation time is 40-60 days to obtain a fermented product; step c) mix the fermented product, 300-1700 parts by weight of low-rank coal, and 60-150 parts by weight of superphosphate, and stir to obtain a special yam planting Soil conditioner.

[0024] The soil requirements for yam growth are: it likes high temperature and dryness, and sandy soil with deep, fertile and loose s...

Embodiment 1

[0054] Wet 500 kg of crushed straw with water dissolved in 1 kg of straw decomposing agent, put it into a fermentation tank about 2 feet deep together with 1000 kg of lignite powder with a particle size not greater than 0.3cm, 500 kg of human and animal manure, and 10 kg of EM bacteria. Stir and cover. After one week, the temperature rises slowly, and the retting is completed after 60 days. At this time, the mixed material is in the shape of dark brown agglomerate particles.

[0055] When planting yam, take it out, add 500 kg of lignite powder and 100 kg of "Jiuhuashan" brand calcium superphosphate produced by Tongguanshan Chemical Co., Ltd. It is in the shape of dark brown granules, and it is added to 1 mu of yam planting soil as a modifier.

[0056] The results after the fall show that the yield of the field applied with the special improver is more than 250 kg per 66.7 square meters, which is 50 kg more than that of the control plot per 66.7 square meters, and the effect o...

Embodiment 2

[0058] Wet 250 kg of crushed straw with water dissolved in 0.5 kg of straw decomposing agent, put it into a fermentation tank about 2 feet deep together with 500 kg of weathered coal powder with a particle size not greater than 0.3cm, 250 kg of human and animal manure, and 5 kg of EM bacteria , stir and cover. After one week, the temperature rises slowly, and the retting is completed after 60 days. At this time, the mixed material is in the shape of dark brown agglomerate particles.

[0059] When planting yam, take it out, then add 250 kg of weathered coal powder and 50 kg of "Jiuhuashan" brand calcium superphosphate produced by Tongguanshan Chemical Co., Ltd. It is in the form of dark brown granules, and it is added to 0.4 mu of yam planting soil as a modifier.

[0060] After autumn, the results showed that the yield of the plot applied with the special improver was more than 245 kg per 66.7 square meters, which was 40 kg more than that of the control plot per 66.7 square me...

Abstract

The invention provides a soil modifier special for Chinese yam planting and a preparation method of the soil modifier. The soil modifier is prepared from low-rank coal, human and animal excreta, driedstraw, EM bacteria, a straw-decomposing inoculant, calcium superphosphate and water. Compared with the prior art, the pulverized coal is added in two times, more humic acid can be quickly generated,moreover, layerwise adsorption heating expansion of the coal is generated in water, and water-retention and heating effects are achieved; the straw is added, organic matter in soil is enriched, and the contents of elements in the soil are equalized; the EM bacteria are added, and breeding of pathogenic microorganisms is effectively controlled. All the raw materials achieve the effects of improvingthe Chinese yam planting soil and promoting yield increasing of Chinese yam, and a high growth promoting effect on late crops is achieved. Therefore, the soil modifier has the effects of improving the Chinese yam planting soil, promoting the growth of Chinese yam, increasing the yield and improving the quality of the Chinese yam. Besides, the raw materials are wide in source, the cost is low, theproduction method is simple, and both volume production and farmer individual production can be achieved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a special soil improver for yam planting and a preparation method. Background technique [0002] Yam, also known as long yam, is a perennial herb with vines, often purple, cylindrical root, opposite leaves, oval or oval, milky white flowers, dioecious, its rhizome is rich in starch and protein, taste and nutrition The value is very high, and it is a vegetable that is widely loved by people; at the same time, yam can also be used as medicine, which can invigorate the spleen and nourish the deficiency, nourish the essence and strengthen the kidney, cure all deficiencies and injuries, and treat five fatigue and seven injuries. Benefiting qi and other effects, it has huge medicinal value, so yam has a great development prospect in medicinal, edible and food processing industries, and the market prospect for planting is broad. [0003] In recent years, dead seedlings and r...
