Embodiment 1

[0036] Example 1 Prepare flue-cured tobacco stereoscopic seedling well cellar-type transplanting covering nutrient soil according to the following steps:

[0037] Firstly, select the raw ore of purple sand shale weathered debris to pass through a 18-mesh sieve, the pH value should be ≤8.0, and the moisture content should be ≤15.0%, take 62.0kg for later use; then, collect the fine river sand on the river bed and dry it in a high place When the water content is ≤15.0%, pass through a 18-mesh sieve, and take 12.0kg for use; then collect the slag from thermal power plants, and require that the total content of heavy metals (cadmium, lead, chromium, nickel) should be ≤10mg / kg, and the moisture content should be ≤ 3.0%, after crushing through a 18-mesh sieve, take 12.0kg for later use; then crush the fully decomposed rapeseed cake squeezed 4 months ago, add water, accumulate and ferment, pass through a 18-mesh sieve, and take 4.5kg for use; Crushed through 18 mesh sieves, its colo...

Embodiment 2

[0038] Example 2 According to the steps of Example 1, 100 kg of nutrient soil was prepared for the three-dimensional cultivation of flue-cured tobacco seedlings in wells and covered with nutrient soil. The dosage of each raw material was: 64.0 kg of purple sand shale weathered debris, 11.0 kg of fine river sand, 11.0 kg of slag from a thermal power plant, and 10 kg of rapeseed Cake fermented decomposed cake fertilizer 4.5kg, superphosphate 5.5kg, potassium chloride 1.8kg, potassium nitrate 2.2kg.

Embodiment 3

[0039] Example 3 According to the steps of Example 1, 100kg of nutrient soil was prepared for the three-dimensional cultivation of flue-cured tobacco seedlings in a cellar. Cake fermented decomposed cake fertilizer 4.5kg, superphosphate 5.5kg, potassium chloride 1.8kg, potassium nitrate 2.2kg.

Abstract

The invention discloses well-type transplanting covering nutrient soil for three-dimensional seedling culturing of flue-cured tobaccos and a preparation method of the well-type transplanting covering nutrient soil. The nutrient soil is prepared from the following raw materials in percentage by mass: 62.0%-66.0% of purple gritstone weathered debris matters, 10.0%-12.0% of fine river sand, 10.0-12.0% of heat-engine plant slag, 4.5%-5.0% of a rapeseed cake fermented and composted cake fertilizer, 5.0%-5.5% of calcium superphosphate, 2.0%-2.2% of potassium nitrate and 1.8%-2.0% of potassium chloride. The nutrient soil disclosed by the invention is exclusively used in covering of roots during three-dimensional seedling culturing tobacco seedling transplanting, and is capable of timely providing nutrients for tobacco seedlings, and promoting tobacco seedling survival, and early growth and quick tiller; the problem of a fine earth source required for sealing of fine three-dimensional seedling culturing seedling transplanting is solved; and the tobacco seedling survival is obviously promoted, and thus the seedling transplanting effect and the normal growth and development of tobacco plants are ensured; the well-type transplanting covering nutrient soil is an optimization measure for tobacco cultivation; the soil improvement and the quality and efficiency improvement of the culturing are facilitated; and the well-type transplanting covering nutrient soil is suitable for being used in departments and farmers of tobacco cultivation.

Description

technical field [0001] The invention belongs to the field of flue-cured tobacco cultivation. Background technique [0002] At present, flue-cured tobacco seedlings mainly adopt two methods of floating seedlings and tray wet seedlings. Since building a large number of seedling greenhouses not only wastes land resources, but also consumes a lot of manpower and material resources, in recent years, the soilless cultivation technology in the principle of plant nutrition has been adopted and replaced by seedling substrates. natural soil. At the same time, Stereo Sports Seedlings has received widespread attention and is developing rapidly. Under the same seedling facilities, vertical seedlings can double the seedling area and efficiency, greatly saving land resources and saving the construction cost of seedling greenhouses. In recent years, flue-cured tobacco transplanting methods have also been innovated. The patented technology ZL201110203197.5 "Transplanting Method of Flue-cur...
