Special strawberry seedling cultivating substrate

Abstract

The invention relates to a special strawberry seedling cultivating substrate. The special strawberry seedling cultivating substrate is mainly composed of the following components, by mass, 60-100 parts of coconut chaff, 10-15 parts of vermiculite, 15-25 parts of waste bacterium rods, 1-3 parts of 10% paclobutrazol wettable powder, 5-8 parts of camphor berries, 20-40 parts of wormcast and 3-8 parts of a water retaining agent; the waste bacterium rods are waste bacterium rods for producing pleurotus eryngii; and kernels of the camphor berries need to be removed, and full fermentation is performed. According to the special strawberry seedling cultivating substrate, the coconut chaff is adopted as a main substrate, the water retaining agent can assist in improving the water retention performance on the basis of guaranteeing the breathability of the substrate, meanwhile, a proper amount of paclobutrazol is added in the substrate and can promote growth of creeping stems and improve the survival rate and quality of strawberry seedling cultivation, and the substrate has the beneficial effects of making seedlings strong and being high in propagation coefficient.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a strawberry seedling-raising substrate. Background technique [0002] Strawberry (scientific name: Fragaria × ananassa Duch.), perennial herb, 10-40 cm high. Stems lower than leaves or nearly equal, densely spread. Yellow pilose. Leaves three out, leaflets with short stalks, thicker in texture, obovate or diamond-shaped, dark green above, almost glabrous, pale green below, sparsely hairy, denser along the veins; petioles are densely covered with yellow pilose. Cymes, with a short-stalked leaflet under the inflorescence; flowers bisexual; sepals ovate, slightly longer than epicalae; petals white, nearly round or obovate-elliptic. The aggregated fruit is large, and the persistent sepals are erect, close to the fruit; the tip of the achene is ovate and smooth. The flowering period is April-May, and the fruiting period is June-July. [0003] At present, the commo...

Problems solved by technology

Since peat soil is a non-renewable resource, developed countries have begun to prohibit the use of peat soil crop seedlings or planting substrates, and the use of peat soil as the main substrate will cause the following disadvantages in the seedling cultivation process: 1) The surface is easy to conjunctival, not easy to Water seepage phenomenon, resulting in water shortage for seedlings after repeated watering; 2) Poor water seepage, after multiple waterings, due to poor water seepage, water is easy to deposit in the lower part of the seedling container, showing water shortage on the top, and excessive water under the substrate Not suitable for root growth

3) Due to the difficulty of water management, it is difficult to produce stolons, and the reproductive coefficient of seedlings is low
