Embodiment 1

[0032] A method for raising tobacco seedlings of secondary filling matrix, comprising the following steps:

[0033] S1. Filling the matrix for the first time: the seedling hole of the counter-hole seedling raising tray is filled with the matrix to the height of 1 / 2 of the hole depth for the first time, and then sowing and the first seedling raising;

[0034] The matrix filled for the first time is the following components calculated by mass percentage: peat 60%, fermented rice husk 20%, puffed perlite 20%;

[0035] The sowing method is as follows: each seedling hole is sown with 1 to 2 coated seeds with a depth of 0.2 to 0.3 cm; water is sprayed on the surface, and the hole seedling tray is put into the seedling pool;

[0036] The conditions for the first seedling cultivation are: the daily minimum temperature is 10°C, the daily maximum temperature is 30°C, and the relative humidity is 75%;

[0037] S2. Filling the matrix for the second time: When the growth point of the toba...

Embodiment 2

[0041] A kind of tobacco seedling raising method of secondary filling matrix, the difference with embodiment 1 is:

[0042] The matrix filled for the first time is the following components calculated by mass percentage: peat 55%, fermented rice husk 25%, puffed perlite 20%;

[0043] The matrix for the second filling is the following components calculated by mass percentage: peat 55%, fermented rice husk 25%, and puffed perlite 20%.

Embodiment 3

[0045] A kind of tobacco seedling raising method of secondary filling matrix, the difference with embodiment 1 is:

[0046] The matrix filled for the first time is the following components calculated by mass percentage: peat 57%, fermented rice husk 20%, puffed perlite 23%;

[0047] The matrix for the second filling is the following components calculated by mass percentage: peat 57%, fermented rice husk 20%, and puffed perlite 23%.

Abstract

The invention provides a tobacco seedling raising method adopting secondary matrix filling, which comprises the following steps: S1, first matrix filling: filling a seedling raising hole of a hole seedling raising tray with the matrix for the first time until the height of the hole is 1 / 2-2 / 3 of the depth of the hole, then sowing, and carrying out first seedling raising; and S2, filling the substrate for the second time: cutting leaves when the growing points of the tobacco seedlings are higher than the tray surface of the hole seedling raising tray, filling the substrate for the second time after cutting the leaves, filling the seedling raising holes, and performing seedling raising for the second time. According to the tobacco seedling raising method, the water content of a substrate is high, coated seeds are easy to crack and germinate, the seeds are not prone to falling off, the survival rate of tobacco seedlings is high, and the green alga occurrence rate is reduced; the growth vigor of the cultivated tobacco seedlings is obviously improved, the stress resistance is improved, and the seedling returning period is shortened.

Description

technical field [0001] The invention relates to the field of tobacco planting, and more particularly, to a method for raising tobacco seedlings with a secondary filling matrix. Background technique [0002] Tobacco seedlings are the basis of tobacco field production, and seedling raising is an important part of flue-cured tobacco production. Since the beginning of tobacco cultivation, tobacco seedlings have gone from traditional seedlings to the more commonly used nutrient blocks, nutrient bowls, and nutrient bags. The technology of tobacco seedlings has been greatly improved. [0003] The well-developed root system of tobacco seedlings is conducive to the nutrient absorption of the roots after transplanting tobacco seedlings, effectively promoting early growth and rapid growth of tobacco plants, early season, growth and income, and can also improve the speed and rate of nutrient absorption. The area increases, and the field growth advantage is obvious, which has won effect...
