Problems solved by technology

[0002] In the process of planting traditional melons, fruits and vegetables, due to continuous planting, continuous cropping obstacles are particularly large, resulting in many diseases and insect pests, and due to long-term use of chemical fertilizers, the soil structure has undergone fundamental changes, such as soil fertility decline, compaction, etc. leading to a severe decline in crop yields
[0003] With the continuous upgrading of agricultural technology research and development, various forms of soilless cultivation models are used to cultivate crops on the basis of traditional planting of crops. At present, the main form of soilless cultivation mode is matrix cultivation, which refers to replacing soil with matrix The roots of the crops are fixed in the substrate, and the crops are supplied with nutrients through drip irrigation or trickle irrigation in soilless cultivation. However, the current cultivation substrate has the disadvantage of poor fertilizer retention effect, which needs to be solved urgently

Abstract

The invention discloses a soilless culture substrate special for moisture and fertility preservation vegetables. The soilless culture substrate is prepared from, by weight, 40-60 parts of molasses, 20-40 parts of composted horse dung, 30-50 parts of sunflower seed meal, 10-20 parts of mushroom dregs, 15-25 parts of rice wine lees, 6-12 parts of cement kiln dust, 2-4 parts of EM bacteria agent and55-60 parts of degradation controlled release agent. The degradation controlled release agent is prepared from, by weight, 8-16 parts of corncob powder, 6-12 parts of talcum powder, 6-14 parts of medical stone meal, 8-14 parts of bentonite, 4-8 parts of borax and 8-12 parts of collagen complex. The preparation technology of the collagen complex comprises the steps that collagen is dissolved into water, the pH value is adjusted to 9.5-10.5, the temperature is adjusted, single epoxy terminated polysiloxane is added under the stirring state, continues stirring is performed, microwave processing is performed, water is removed through distillation, and the collagen complex is obtained through freeze drying.
