Sacsaoul seedling cultural method under production condition of construction agriculture

Abstract

The invention relates to a sacsaoul seedling cultural method in green house under the condition of construction agriculture in northwestern area of China, belonging to the field of forestry cultivation. The method comprises the follows steps: preparing nutritional matrix from desert sand, vermiculite, pearlite and sheep manure according to a certain proportion, filling a seedling tray with the nutritional matrix; sowing sacsaoul seeds on the nutritional matrix in the seedling tray, and keeping suitable growth conditions such as temperature, illumination, humidity, water content and the like for container seedlings; starting to separate the seedlings after 55 days, transplanting the separated seedlings to a seedling cultural container, top dressing and control diseases, pests and weed in time; after the seedling age reaches 100-120 days, taking the seedlings as finished seedlings for sell. The sacsaoul container seedlings cultivated by the method has the characteristics of 20-40cm of plant height, emerald green color, straight and robust shape and strong disease resistance, and has the advantages of being not limited by seasons, having high seedling survival rate and being not easy to damage roots when seedlings are transplanted. The invention has strong operability, good repeatability, high efficiency and simple method and can be used for mass culture of sacsaoul seedlings.

Description
