Problems solved by technology

[0004] In summary, in order to overcome the deficiencies of the prior art problems, the present invention provides a kind of substrate for floating seedlings of tobacco, which utilizes the chaff after pulverizing and charring Instead of most of the peat, carbonized chaff is mixed evenly with peat, vermiculite and expanded perlite according to a certain volume ratio to make a substrate for floating seedlings of tobacco. Carbonized chaff is rich in raw materials and low in cost, which overcomes the existing Peat resources are limited, substrate cost is high and other disadvantages, the tobacco seedlings cultivated by the present invention have well-developed root system, thick stems, good overall quality, and high survival rate of tobacco seedlings after transplanting

Embodiment 1

[0021] A substrate for floating seedlings of tobacco, the volume percentage of each component is: peat: 10%, carbonized chaff: 50%, expanded perlite: 20%; vermiculite: 20%.

[0022] Yunyan 87 was used as the experimental tobacco species, coated seeds, special fertilizer for floating seedlings and 200-hole floating trays were used, and the special fertilizer for floating seedlings was according to N:P 2 o 5 :K 2 O=2:1:2 ratio configuration, and contains a variety of trace elements.

[0023] Fill the matrix configured according to the above ratio into the holes of the floating tray, and plant tobacco seeds, fill the two floating trays, and apply the special fertilizer for floating seedlings at the time of sowing, 30 days after sowing, and 45 days after sowing, so that the seedlings can grow The concentration of nitrogen fertilizer in the pool reaches 100mg / kg, 100mg / kg, and 50mg / kg respectively; the seedlings are thinned and fixed at the small cross stage to make the tobacco s...

Embodiment 2

[0025] Repeat Example 1 with the following differences. The volume percentage of each component is: peat: 5%, carbonized chaff: 45%, expanded perlite: 25%; vermiculite: 25%.

Embodiment 3

[0027] Repeat Example 1 with the following differences. The volume percentage of each component is: peat: 15%, carbonized chaff: 55%, expanded perlite: 15%; vermiculite: 15%.

Abstract

The invention relates to a matrix for tobacco floating seedling. The matrix comprises the following components in percent by volume: 5% to 15% of peat, 45% to 55% of carbonized rice husks, 15% to 25% of inflated pearlite and 15% to 25% of vermiculite. The grain diameter of the inflated pearlite is 1-3 mm. The grain diameter of the vermiculite is 1-3 mm. The rice husks after smashing carbonization are utilized for replacing at least partial peat or even completely replacing the peat, the carbonized rice husks, the vermiculite and the inflated pearlite are uniformly mixed in a certain volume ratio to prepare the matrix for tobacco floating seedling, the carbonized rice husks are abundant in raw materials and low in cost, and the disadvantages that existing peat resources are limited and the matrix is high in cost are overcome. A tobacco root system cultivated by the matrix is developed, and is stocky in stems, good in comprehensive quality and high in survival rate of tobacco seedling transplanting.

Description

Technical field: [0001] The invention belongs to the technical field of tobacco seedling cultivation, and in particular relates to a substrate for floating tobacco seedling cultivation. Background technique: [0002] Floating seedlings, also known as floating planting, is a new method of raising seedlings. It is to float the foam trays equipped with light seedling substrates on the water surface, sow the seeds in the substrates, and the seedlings will take root in the substrates and grow from the substrates. And the seedling raising method of absorbing water and nutrient in water bed. Beginning in the late 1980s, American Tobacco adopted the floating seedling method for seedling cultivation. Compared with the traditional seedling raising method, it has the advantages of reducing the labor for transplanting, saving the land for seedling raising, facilitating the management of tobacco seedlings, helping to cultivate strong seedlings, and improving the seedling rate.
