Embodiment Construction

[0012] The sawdust soilless culture substrate provided by the present invention and its preparation method are further described below.

[0013] The invention provides a method for preparing a sawdust soilless culture substrate; the preparation method of the sawdust soilless cultivation substrate comprises the following steps:

[0014] (1) Add water to the sawdust, the amount of water added is to make the sawdust saturated with water, and it is advisable to just ooze water;

[0015] (2) Add vitriol and urea to the sawdust after adding water, and stir so that vitriol and urea are evenly distributed in the sawdust, wherein, the addition of vitriol is 1 kilogram per cubic meter of sawdust ~ 3 kg per cubic meter of sawdust, the amount of urea added is 0.5 kg per cubic meter of sawdust to 1.5 kg per cubic meter of sawdust; and

[0016] (3) The sawdust added with vitriol and urea is subjected to open-air fermentation treatment, wherein the time of the fermentation treatment is 40 d...

Abstract

The invention relates to a preparation method of a saw dust soilless culture substrate. The preparation method comprises the following steps: (1) adding water into saw dust until water saturation is reached and water seeps exactly; (2) adding copperas and urea into the saw dust added with water, and overturning and stirring to uniformly distribute copperas and urea in the saw dust, wherein 1kg-2kg of copperas is added into each cubic meter of saw dust and 0.5kg-1.5kg of urea is added into each cubic meter of saw dust; and (3) fermenting the saw dust added with copperas and urea for 40-60 days in open air, so as to obtain the saw dust soilless culture substrate. The invention further relates to the saw dust soilless culture substrate prepared by virtue of the preparation method.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a sawdust soilless culture substrate and a preparation method thereof. Background technique [0002] Soilless cultivation is an advanced cultivation method, which is widely used in flower seedling cultivation, vegetable cultivation, etc. because of its advantages of light weight, cleanliness, no weeds, and avoiding soil pollution. The existing soilless cultivation substrates include peat, rock wool, perlite, sawdust, etc. Among them, sawdust is the leftovers in wood processing, because it has the advantages of wide sources, low cost and easy storage, so it is favored by people. However, unfermented sawdust contains resins, phenols, tannins and other substances harmful to plants, which cannot be used directly, and also has the disadvantages of poor water absorption and cohesiveness, so fermentation treatment is required. However, since sawdust contains a large amou...
