Special bag cultivating medium for cucumbers and preparation method of bag cultivating medium

Abstract

The invention provides a special bag cultivating medium for cucumbers. The medium is prepared from the following raw materials of a mushroom dreg fermentation product, a livestock excrement fermentation product and fine slag in a in volume ratio of (1-5): (2-6): (2-4). The invention further provides a preparation method. The bag cultivating medium special for cucumbers and the preparation method thereof have the characteristics and advantages that the water retention capacity and the fertility retention capacity of the medium are obviously improved, the nutrient supply is sufficient, growth vigor of cucumber plants is good, and the plant height and the stem diameter are effectively improved; and the preparation method of the medium is simple to operate, fermentation time is greatly shortened, the fermentation condition is relatively low, and the medium can effectively adapt to large-scale planting of Gobi sunlight greenhouse bag type cultivation cucumbers.

Description

technical field [0001] The invention relates to the technical field of crop cultivation and planting, in particular to a special bag cultivation substrate for cucumbers and a preparation method thereof. Background technique [0002] Bag culture is a newly developed cultivation method in facility soilless cultivation. The main method is to put a certain amount of substrate into a plastic bag for crop cultivation. While choosing a cultivation bag with strong air permeability, the substrate is the key factor that determines the growth of plant roots. The most important factor of the environment, the characteristics of the substrate affect the plant's absorption of nutrients, water and root growth. [0003] The cultivation medium originally originated from the concept of soilless cultivation, which means that the soil environment around the crops has deteriorated, which seriously affects the yield and quality of the crops. The planters turn to find alternatives, fix the plant ro...

AI Technical Summary

Problems solved by technology

The cultivation effect of sawdust is relatively better, with strong water and fertility retention, rich organic components, and high yield, but sawdust must be fully fermented for more than 3 years before it can be effectively used

Although the carbonized chaff does not need to be fully fermented, it can be used immediately after carbonization, but due to its poor water and fertility retention and poor nutrient supply, the growth of the plant is relatively poor
