Embodiment 1

[0026] Embodiment 1 Rhubarb greenhouse seedling cultivation of the present invention

[0027] (1) Seedling raising method

[0028] 1. Site selection

[0029] Choose an open terrain within the range of 500-3500m above sea level, without tall trees or buildings, with convenient transportation, sufficient water and electricity, convenient drainage and irrigation, no water quality and air pollution around, sheltered from the wind and facing the sun.

[0030] 2. Construction of nursery facilities

[0031] 1. Steel frame greenhouse

[0032] In high-altitude (1500-3500m) areas, the temperature is low in winter and the wind and snow are heavy, so it is advisable to use steel frame greenhouses to resist wind and snow. Steel frame greenhouses can also be used at medium and low altitudes (500-1500m).

[0033] The steel frame greenhouse is 6-10m wide and 50-150m long, which can be designed according to the terrain and the scale of seedling cultivation. The height of the side of the s...

Abstract

The invention discloses a method of raising rhubarb seedlings in greenhouses. The method includes the steps of 1, building a greenhouse and preparing a land; 2, sowing seeds of rhubarb; 3, raising seedlings at the greenhouse temperature of 10 DEG C-30 DEG C under the air humidity of 40%-80%; 4, cultivating until the diameter of rootstalks of the rhubarb seedlings is not smaller than 1cm. The method has the advantages that emergence rate is high, emergence time is short, raised plants are neat and robust, the cost is low, and economic benefit is great.
