Embodiment 1

[0033] Example 1 Follow the steps below to prepare flue-cured tobacco pit-type transplanting and sealing nutrient soil

[0034] First, select the raw ore of granite weathering debris, pass through a 10-mesh sieve, and take 68.0 kg of granite weathering debris for later use; collect slag from a thermal power plant, crush it through a 10-mesh sieve, and take 12.0 kg of fine slag for later use; use biomass materials such as straw, Hay, branches, leaves, sawdust, etc. were heated in a biomass carbonization furnace to prepare biochar, crushed through a 10-mesh sieve, and then 6.0 kg of charcoal powder was taken for use; the above-mentioned reserve materials were mixed with P 2 o 5 6.0kg of phosphate rock powder ≥15%, 4.5kg of calcium magnesium phosphate fertilizer meeting national standards, 1.5kg of potassium chloride, 1.5kg of ammonium nitrate and 0.5kg of diammonium phosphate, mix well, and finally stir evenly with a mixer to get flue-cured tobacco well 100kg of nutrient soil...

Embodiment 2

[0035] Example 2 According to the steps of Example 1, 100 kg of flue-cured tobacco pit type transplanting and sealing nutrient soil were prepared, and the amount of each raw material was: 70.0 kg of weathered granite debris, 14.0 kg of fine slag from a thermal power plant, 7.0 kg of biomass charcoal powder, containing P 2 o 5 ≥15% phosphate rock powder 4.0kg, calcium magnesium phosphate fertilizer meeting national standards 2.5kg, potassium chloride 1.0kg, ammonium nitrate 1.0kg and diammonium phosphate 0.5kg.

Embodiment 3

[0036] Example 3 According to the steps of Example 1, 100 kg of flue-cured tobacco pit type transplanting and sealing nutrient soil were prepared, and the amount of each raw material was: 72.0 kg of weathered granite debris, 14.0 kg of fine slag from a thermal power plant, 6.0 kg of biomass charcoal powder, containing P 2 o 5 6.0kg of phosphate rock powder ≥15%, 2.5kg of calcium magnesium phosphate fertilizer meeting national standards, 0.5kg of potassium chloride, 0.5kg of ammonium nitrate and 0.5kg of diammonium phosphate.

Abstract

The invention discloses a sealing nutrient soil used for well-cellar flue-cured tobacco transplanting and a preparation method for the sealing nutrient soil. The sealing nutrient soil is prepared from the following raw materials by mass percent: 68.0-72.0% of weathered granite debris, 12.0-16.0% of furnace slag from thermal power plants, 6.0-8.0% of biomass charcoal rich in plant fiber, 4.0-6.0% of ground phosphate rock, 2.5-4.5% of a calcium-magnesium-phosphate fertilizer, 0.5-1.5% of potassium chloride, 0.5-1.5% of ammonium nitrate and 0.5-1.5% of diammonium phosphate. The sealing nutrient soil has the advantages that not only is the problem about sources of fine soil required by sealing for the well-cellar seedling transplanting solved, but also the early growth and quick tillering of tobacco seedlings can be promoted, so that the seedling transplanting effect and the normal growth and development of tobacco plants can be guaranteed; tobacco planting is optimized; convenience is brought for the soil improvement and the improvement in the flue-cured tobacco quality and production efficiency. Therefore, the sealing nutrient soil and the preparation method thereof are suitable for departments and farmers engaged in the tobacco planting.

Description

technical field [0001] The invention belongs to the field of flue-cured tobacco cultivation. Background technique [0002] The patented technology (ZL201110203197.5) of "Transplanting Method of Flue-cured Tobacco Mulching Well Cellar Seedlings" has been widely promoted and applied in flue-cured tobacco planting areas. According to incomplete statistics, the accumulative promotion and application area of ​​this technology in Guizhou tobacco area has exceeded 200,000 hectares. At present, this patented technology has begun to be popularized and applied in flue-cured tobacco planting areas such as Hubei, Hunan, Chongqing, Shaanxi, and Yunnan. [0003] Flue-cured tobacco plastic-film well cellar seedling transplanting technology refers to drilling transplanting holes similar to well cellars on the ridge covered with plastic film, and then putting robust small tobacco seedlings with substrate into the holes, and then pouring into the solvent along the cellar wall. The cultivatio...
