Embodiment 1

[0032] The preparation of embodiment 1 strawberry seedling raising substrate

[0033] 1. Preparation of vermicompost

[0034] First stack the cow dung in the greenhouse, the thickness of the cow dung is about 20cm, and pre-pile it for a week, then inoculate earthworms according to 3‰ of the cow dung quality, and finally spread a layer of 2-3 cm thick rice straw on the material for Shade and moisturize; water at the right time to ensure a relative humidity of 60-70% and a temperature of 20-30°C; after the earthworms are fully fed, the cow dung is all transformed into vermicompost, and then the earthworms are separated by scraping the skin and removing the heart. The separated vermicompost is passed through a 5mm mesh sieve to obtain the vermicompost for preparing strawberry seedling substrate, which is preserved. The physical and chemical properties of the prepared vermicompost are shown in Table 1.

Embodiment 2

[0048] Example 2 Strawberry Seedling Substrate Experiment

[0049] Strawberry seedlings are raised in racks and managed in a unified manner in the field. After the first order of stolons is released, they are fixed in the small substrate grooves on both sides of the matrix frame, and cultivated with the same treated substrate, which is conducive to the growth of the second order of strawberry stolons. It is convenient for cutting seedlings in the later stage of seedling cultivation.

[0050] Watering: Drip irrigation is used, and the mother plant is watered at 9:00 am and 3:00 pm every day within 1 week after planting, and once a week at 9:00 am every day after 1 week, to keep the moisture content of the substrate at 15% to 30%.

[0051] Fertilization: Strawberry seedlings are raised in racks. Before seedlings, dissolve the particles of slow-release fertilizer (Jiamagao Green Fertilizer Water-soluble Fertilizer GM 20-20-20) in clean water, and apply them into the substrate wit...

Abstract

The invention discloses a strawberry seedling substrate, and a production method and application thereof. The substrate comprises the following components: earthworm cast, peat, perlite and vermiculite, wherein the volume ratio of earthworm cast, peat, perlite to vermiculite is (1-4):(0-4):1:1; the earthworm cast is a product formed by earthworms taking cow dung. According to the strawberry seedling substrate, and the production method and application thereof, peat is replaced with the earthworm cast obtained by raising the earthworms fed with cow dung, so that resourceful utilization channels of the earthworm cast are expanded, environmental pollution is reduced, the ecological environment is protected, and the recycling and low-carbon circulation of resources are realized; adequate nutrients can be provided for strawberries in a seedling period, chlorophyll synthesis can be promoted, and the activity of peroxidase in strawberry leaves can be improved; the rooting of maternal seedlings and the growth of creeping stems are promoted, the strawberry seedling quality is improved, the rooting rate is increased, high survival rate and seedling uniformity in the seedling period are ensured, the number of strong seedlings is remarkably increased, seedling lifting labor is saved, and convenience in operation and transportation is ensured.

Description

technical field [0001] The invention belongs to the field of biological treatment and resource utilization of agricultural solid waste, and relates to a strawberry seedling raising substrate and its production method and application, in particular to a strawberry seedling raising substrate made of vermicompost, its production method and its application. Background technique [0002] Strawberry is a perennial herbaceous plant of Rosaceae and Fragaria genus. The fruit is gorgeous, tender and juicy, and contains strong fruit aroma. Strawberry has high nutritional value and is an economic crop with short cultivation period, early results and quick results. Strawberry likes light, fertilizer, and water, and is not resistant to waterlogging. It is suitable for growing in a substrate with a pH of about 6.5 and an electrical conductivity of about 1.5mS / cm. At present, strawberry seedlings mostly use traditional simple substrates such as perlite, vermiculite, peat, etc., and the pH ...
