Embodiment Construction

[0028] The open water infiltration irrigation method used for crop cultivation in flue-cured tobacco seedling greenhouses uses artificial soil for cultivation in flue-cured tobacco seedling greenhouses, and infiltrates a solution with a certain concentration of nutrients into the artificial soil to supply crops to grow and maintain continuous and sufficient water and nutrient supply for crops , to adjust the crop growth temperature; the artificial soil is a mixture of flue-cured tobacco seedling raising substrate, uncontaminated loess and cake fertilizer, and the flue-cured tobacco seedling raising substrate adopts configurations such as peat, vermiculite, perlite, carbonized chaff, and fermented bacteria residue, among which The amount of loess accounts for 10-60% of the total volume of artificial soil, the amount of cake fertilizer accounts for 3-10% of the total volume of artificial soil, and the bulk density of artificial soil is 0.4-1.0g / cm 3 , the organic matter content is ...

Abstract

The invention discloses an open water permeating irrigation method used for crop culture of a flue-cured tobacco seedling culture greenhouse. Man-made soil culture is utilized in the flue-cured tobacco seedling culture greenhouse, a solution dissolved with certain concentration of nutrient is permeated into man-made soil to supply crop growth, continuous and enough moisture and nutrient supply is kept for crops, and the growth temperature of the crops is adjusted. The method comprises three manners suitable for different types of crops: 1, under-water-level multidirectional permeating method; 2, moisture-passing-bottom-layer permeating method; 3, man-made soil permeating method. The open water permeating method better solves the problem that the crops with longer high-temperature period are larger in water consumption, then is particularly suitable for follow-up utilization of the flue-cured tobacco greenhouse, absorbs the advantages of soil culture, soilless culture, surface irrigation and drop irrigation, overcomes the defects, obviously enlarges the crop root system size, reduces the rhizosphere temperature, promotes crop growth, obviously reduces substrate and fertilizer cost, and is wide in application, flexible in manner, simple to operate, and obvious in benefit.

Description

technical field [0001] The invention relates to an irrigation method for growing flue-cured tobacco seedlings in greenhouses. Background technique [0002] With the development of modern tobacco agriculture, a large number of seedling greenhouses have been built in various tobacco leaf producing areas across the country, providing important facilities for the intensive cultivation of flue-cured tobacco. Tobacco factory floating seedling cultivation has the advantages of high degree of intensification, saving seedbeds, simplifying the management of tobacco seedlings, increasing the rate of seedlings, reducing labor for transplanting, shortening the slow seedling period, etc., and has broad development and application prospects. However, due to the seasonality of tobacco leaf production, most of the tobacco facilities have a single purpose, a long idle time, and high maintenance costs, resulting in seasonal idleness of these assets. Created invisible waste. It not only reduc...
