Tomato seedling growing method by utilizing tidal irrigation seedbed equipment

Abstract

The invention discloses a tomato seedling growing method by utilizing tidal irrigation seedbed equipment. The method comprises the following steps that (1) germination accelerating is conducted for 40-50 hours; (2) seedling growing discs and a substrate are prepared; (3) sowing is conducted, wherein seeds just sprouting are sown in seedling growing hole discs in a bunch planting mode, the substrate is used for covering the seeds, and the hole discs are gathered on a tidal seedling growing plate; (4) water is supplied to the seedling growing plate until the water content of the hole disc substrate is enough; (5) the tidal seedling growing plate is covered with a sunshade net, and when the emergence rate reaches 30%, the sunshade net is uncovered; (6) the temperature of the inside of a seedling growing greenhouse is 20-25 DEG C in the daytime, and the temperature of the inside of the greenhouse is higher than or equal to 12 DEG C at night; (7) water management is conducted, wherein afterall seedlings emerge, water is supplied according to the principle that the substrate surface layer is dry and clean and the parts below the surface layer are wet; (8) after two main leaves unfold, nutrient liquid is supplied; (9) disease and insect pest management is conducted in the seedling stage. The method combines the advantages of hole disc seedling growing and floating disc seedling growing, the emerging seedlings are even, diseases in the seedling stage cannot be easily caused, water and nutrient liquid are mechanically supplied, and the operation is simple.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a method for growing tomato seedlings by using tidal irrigation seedbed equipment. Background technique [0002] At present, there are mainly two kinds of tomato seedling raising techniques: hole tray seedling raising and floating tray seedling raising. Both seedling raising techniques have commonality and advantages and disadvantages respectively. The commonality is that both of them are carried out in greenhouses, and the purpose is to avoid rain. For plug seedling cultivation, the advantage is that watering can be controlled in the middle and later stages to achieve the purpose of cultivating strong seedlings; the disadvantage is that artificial watering and fertilization are uneven, seedlings are not neat, and in the middle and later stages, it is easy to form the phenomenon that the middle seedlings are strong and the edge seedlings are weak, and The degree o...

Problems solved by technology

For plug seedling cultivation, the advantage is that watering can be controlled in the middle and later stages to achieve the purpose of cultivating strong seedlings; the disadvantage is that artificial watering and fertilization are uneven, seedlings are not neat, and in the middle and later stages, it is easy to form the phenomenon that the middle seedlings are strong and the edge seedlings are weak, and A high degree of attention to seedling cultivation and a large labor export

The advantage of floating tray seedlings is that the seedlings emerge neatly, and the degree of attention is low. It is a model of light, simplified and labor-saving cultivation techniques; the disadvantage is that when the seedling temperature is low in early spring, the humidity in the shed is high, and damping-off is prone to occur at the seedling stage, so it is not suitable for floating tray seedlings; , In addition, the floating seedling tray floats on the water surface for a long time, the seedlings grow fast, and it is easy to form leggy seedlings, and the slow seedling period is long after planting in the open field, and even easy to die
