Embodiment 1
[0033] A method for cultivating tobacco seedlings for drought resistance, water retention, early growth and fast growth, comprising the following steps:
[0034] Step 1: Mulch seedlings on floating trays
[0035] Use floating plate mulch to grow seedlings, put the seedling cultivation soil into the floating plate, then pour water thoroughly, put 2-3 seeds in each floating plate, sprinkle a layer of nutrient soil to spray wet, lay on the floating plate after sowing A layer of straw keeps moisture; spray water on the straw every 2-3 days, and remove the straw after the bag sprouts.
[0036] Step 2: Soil preparation and ridging
[0037] In the spring of the next year, select suitable land for site preparation, and then perform deep plowing, site preparation and ridges. When the site is ridged, the distance between the ridges is 100-130 cm, and the height of the ridges is 35-30 cm. Dig the drainage ditch, and water the transplanting ground 2-3 days before the tobacco seedlings a...

Abstract
The invention discloses a cultivation method for drought resistance, water retention, early growth and rapid development of tobacco seedlings. The cultivation method comprises the steps such as floating tray root protection seedling-raising, land preparation and ridging, mulch film covering, base fertilizer applying, tobacco seedling transplanting, tobacco seedling topping, and field management. The cultivation method adopts floating tray root protection seedling-raising during the tobacco seedling raising period, the survival rate of the tobacco seedlings can be effectively improved, the rootsystem of the tobacco seedlings can be protected, and the root system is ensured to be complete when the tobacco seedlings are transplanted. Land ridges are irrigated before the tobacco seedlings aretransplanted to guarantee the water content of the planting land, the soil water content is maintained through the film covering treatment, and thereby the drought resistance and water retention capacity is ensured. Before transplanting, transplanting holes are dug and a drought resistance and water retention biological fertilizer is applied, a base fertilizer is provided for the tobacco seedlings and the drought resistance and water retention capacity of the tobacco seedlings is improved, and the survival rate of the tobacco seedlings after transplanting is improved. The topping operation isperformed 8-10 days after tobacco transplanting, axillary buds are left to grow, the root system growth of the tobacco seedlings can be promoted, and the growth potential energy is accumulated.
Description
technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a drought-resistant, water-retaining, early-growing and fast-growing cultivation method for tobacco seedlings. Background technique [0002] Tobacco is a relatively special economic crop with strong ecological adaptability. It is planted all over the country. Tobacco planting needs to be transplanted. When tobacco is cultivated, it is generally necessary to lay base fertilizer in the field, then ridges, and then Dig transplanting pits for transplanting, and carry out scientific and reasonable field management after transplanting. The root system of the newly transplanted tobacco seedlings is relatively fragile, and their ability to absorb fertilizer and water is relatively poor, resulting in a longer seedling period and even the death of tobacco seedlings. Therefore, in the cultivation process of tobacco seedlings, it is necessary to improve the survival rate and growth...
