Embodiment 1

[0050] Such as figure 1 As shown, the invention provides a technical solution: a method for growing tobacco seedlings by floating, which specifically includes the following steps:

[0051] Step 1: Disinfection: use the floating plate for more than one year, clean and disinfect the sundries attached to the floating plate before raising seedlings, and soak each hole of the floating plate with 25% metalaxyl mancozeb 300 times solution , take it out and stack it neatly, cover it with film and cover it for 24 hours, rinse it once with clean water while the water is still wet, and dry it for later use;

[0052] Step 2: Leveling the nutrient pool, padding film, and adding water: 7-10 days before sowing, firstly level the nutrient pool without hardening, take out the stones and sand in the pool; then place the nutrient pool pad After the membrane is well cushioned, put 8-10 cm deep well water or tap water; finally, sprinkle 15-20 grams of powdered bleach per ton of water directly int...

Embodiment 2

[0088] Such as figure 1 Shown, a kind of tobacco planting floating seedling raising method specifically comprises the following steps:

[0089] Step 1: Disinfection: Use the floating tray for more than one year, clean and disinfect the sundries attached to the floating tray before raising seedlings, and use 1-2% formalin or 0.5-0.1% permanganate Potassium solution spraying, cover film fumigation for 1-2 days, and then rinse with clean water;

[0090] Step 2: Leveling the nutrient pool, padding film, and adding water: 7-10 days before sowing, firstly level the nutrient pool without hardening, take out the stones and sand in the pool; then place the nutrient pool pad After the membrane is well cushioned, put 8-10 cm deep well water or tap water; finally, sprinkle 15-20 grams of powdered bleach per ton of water directly into the pool water for disinfection, and stir the pool water to let the chlorine gas overflow, seal the greenhouse, and preheat the pool water. It is also conv...

Embodiment 3

[0126] Such as figure 1 Shown, a kind of tobacco planting floating seedling raising method specifically comprises the following steps:

[0127] Step 1: Disinfection: Use the floating tray for more than one year, clean and disinfect the sundries attached to the floating tray before raising seedlings, soak the floating tray with clarified lime water with a ratio of 4:100, and dry it for later use ;

[0128] Step 2: Leveling the nutrient pool, padding film, and adding water: 7-10 days before sowing, firstly level the nutrient pool without hardening, take out the stones and sand in the pool; then place the nutrient pool pad After the membrane is well cushioned, put 8-10 cm deep well water or tap water; finally, sprinkle 15-20 grams of powdered bleach per ton of water directly into the pool water for disinfection, and stir the pool water to let the chlorine gas overflow, seal the greenhouse, and preheat the pool water. It is also convenient to check whether the nutrient pool is l...

Abstract

The invention discloses a floating seedling raising method for tobacco planting, which comprises the specific steps of I, disinfecting; II, leveling a nutrient pool, padding with a film, and adding water; III, loading trays; IV, seeding; V, managing a nutrient solution; and VI, providing seedling stage management. A floating seedling raising field before disinfection and floating seedling raisingequipment are selected; disinfection management after seedling management is provided; the whole floating seedling raising method and system for tobacco planting are complete, so that the problems ofseedling burning, low growth speed, uneven growth speed and proneness to anoxic decay existing in common floating seedling raising for tobacco panting are solved, the yield and quality of tobacco cultivation production are increased, the harvest time is prolonged, and the use amount of pesticides is limited and reduced.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a floating seedling raising method for tobacco planting. Background technique [0002] In order to solve the difficulty in controlling the nutrition in the traditional tobacco planting process and the high difficulty of soil pests and diseases, a new method of tobacco planting and seedling cultivation was invented, that is, tobacco planting floating seedling cultivation, which is a foam with a light seedling substrate The plug tray floats on the water surface, the seeds are sown in the substrate, and the tobacco seedlings take root and grow in the seedling substrate, and can absorb water and nutrients from the substrate and the water bed. It mainly includes pre-cultivation sterilization, including sterilization of the floating tray and Substrate sterilization, seeding and floating culture and other steps. Tobacco planting floating seedlings began in the late 1980s, and ...
