CN103430819A - Soilless culture substrate for strawberry - Google Patents

Abstract

The invention provides soilless culture substrate for strawberry, and relates to the technical field of agriculture. The soilless culture substrate is prepared through the following method of firstly, uniformly mixing a solid material which is smashed into 6 to 9mm with pig manure, so as to obtain solid substrate, secondly, spraying nutrient solution to the solid substrate obtained in the first step, and uniformly blending the nutrient solution and the solid substrate, and thirdly, placing the nutrient solution and the solid substrate for 11 to 12 days at 15 to 30 DEG C, and ensuring that the nutrient solution and the solid substrate natural fermentation is subjected to natural fermentation, so as to obtain the soilless culture substrate. By adopting the soilless culture substrate provided by the invention, insect pests which occur when soil culture is adopted can be reduced, the yield is improved, and the cost is lowered and the usage amount of pesticide is reduced.

Description

Technical field

The present invention relates to agricultural technology field, be specifically related to the soilless culture substrate of a kind of strawberry.

Background technology

In prior art, the size of population sharply increases, and the per capita cultivated land day by day reduces, and the soil in arid area and saline land is unsuitable for farming.At soil planting crop, a lot of insect ovum are arranged in soil, during planting, need often to spray insecticide, easily contaminated soil, water and crops.

Summary of the invention

The invention provides the soilless culture substrate of a kind of strawberry, can reduce the insect pest while adopting soil cultivation, improve output, reduce costs, reduce the agricultural chemicals usage amount.

The soilless culture substrate of a kind of strawberry, employing is prepared as follows method and obtains:

(1) mix with pig manure after solid material being crushed to 6-9mm, obtain solid matrix;

(2), to the described solid matrix of step (1), spray nutrient solution uniform mixing;

(3) place 11-12 days at 15-30 ℃, spontaneous fermentation, obtain soilless culture substrate.

Described nutrient solution is the aqueous solution that contains following concentration composition: sodium nitrate 5-6 grams per liter, urea 3-4 grams per liter, copper nitrate 2-3 mg/litre, manganese nitrate 4-5 mg/litre, ferrous sulfate 45-65 mg/litre, ammonium phosphate 3-5 mg/litre.

Described solid material is one or more the mixture in gardens fallen leaves, deadwood, stalk, sawdust, bark and wood shavings.

Described solid material is that 50:1-2 mixes with pig manure according to weight ratio.

The weight ratio of described solid matrix and nutrient solution is 50:1-2.

Beneficial effect:

Soilless culture substrate provided by the invention, can reduce the insect pest while adopting soil cultivation, improves output, reduces costs, and reduces the agricultural chemicals usage amount.
