Composite substrate for strawberry soilless potting

Abstract

The invention relates to a compound substrate for strawberry soilless potted plants. The compound substrate comprises 3-5 parts of turf, 2 parts of perlite, 1 part of river sand and an appropriate amount of fertilizer based on volume parts, wherein the turf is coarse turf having the grain size of 10-30mm; the river sand is fine sand for a construction site which is screened with a sieve having the mesh size of 2-4mm; before potting, 20kg of organic fertilizer, 10kg of vegetable cake fertilizer and 0.5kg of compound fertilizer are added in the substrate per cubic meter according to a ratio of 15: 15: 15. The compound substrate has the physical and chemical indexes that the PH is 5.5-6.5, the conductivity is 0.5-2ms / cm, the volume weight is 0.3-0.5g / cm<3>, the total porosity is 55-60, the aeration pore is 20-22 percent, the water retention pore is 35-40 percent and the gas-to-water ratio is 1:(1.5-2.0). As strawberries are planted in pots, the soil-borne disease is eliminated, and the quality and the content of the strawberry fruits are improved by about 20 percent; the compound substrate has relatively high practical value; in addition, the plants have more root systems, grow luxuriantly and accord with the attractive effect of potted landscapes.

Description

technical field [0001] The invention relates to a cultivation substrate, in particular to a composite substrate for soilless potting of strawberries. Background technique [0002] Soilless substrate cultivation has the following advantages: (1) It is not limited by soil conditions and can be cultivated in places and environments that are not suitable for soil cultivation. It can be carried out in areas with poor soil, arid areas, and saline-alkali land, making full use of land resources. (2) The solid substrate has a strong permeability to water and air, which makes it easier to adjust the water and air in the root environment and is more conducive to the development of the root system. (3) Irrigation and fertilization are relatively accurate, and can accurately supply the water and nutrients needed by crops according to the needs of water and nutrients in different growth stages of crops. It is easy to obtain high yield, and the product quality is improved. (4) Can avoid...

But for strawberry cultivation, its high water holding capacity is a disadvantage

Strawberries are afraid of waterlogging. The large water holding capacity of peat is not good for the growth of strawberry root system. It is prone to hypoxia and the survival rate is relatively low.

[0004] At present, peat is widely used as a cultivation substrate in production, but peat is expensive and resources are limited, so it is not suitable to use in large quantities.
