3894 results about "Crop yield" patented technology

In agriculture, crop yield (also known as "agricultural output") refers to both agrivet and culture that can measure of the yield of a crop per unit area of land cultivation, and the seed generation of the plant itself (e.g. if three grains are harvested for each grain seeded, the resulting yield is 1:3). That figure, 1:3, is considered by agronomists as the minimum required to sustain human life.

Fermented alga liquid fertilizer synergist and production method and application thereof

The invention relates to a fermented alga liquid fertilizer synergist and a production method and an application thereof. The fertilizer synergist is a fermented alga liquid fertilizer synergist obtained by performing microbial fermentation on natural alga serving as a raw material, preparing an alga extracting solution through procedures such as alkali extraction, filter pressing and the like, and adding chelated state trace elements into a liquid. Due to the adoption of the fermented alga liquid fertilizer synergist disclosed by the invention, the soil urease activity can be suppressed remarkably, slow release of a fertilizer is enhanced, and the crop yield can be increased remarkably; trace elements such as boron, zinc, manganese and the like which are generally lacked in soil in China can be replenished; root growth of crops can be facilitated, root activity is increased, and the capabilities of crops of absorbing phosphorus, potassium and medium and trace elements are increased; and the fermented alga liquid fertilizer synergist has the characteristics of reduction in nutrient loss, avoidance of secondary pollution, reduction in the production cost of a synergic fertilizer, wide raw material source, convenience for adding in fertilizer production and the like, and has a wide application prospect in the production of the synergic fertilizer.

Method producing seaweed fertilizer by processing Entermorpha prolifera by microbial fermentation method

The invention provides a method for producing a seaweed fertilizer by processing Enteromorpha through microorganism fermentation method, which is characterized in that: fresh Enteromorpha is used as the material without being added with any chemical products, and treated by fermentation in large scale by preparing an Enteromorpha seed liquid, so as to dissolve out the effective components of Enteromorpha, thereby largely preserving the effective components with natural activity in the Enteromorpha, and then various Enteromorpha seaweed fertilizers are prepared by taking the fermentation liquid as a basic liquid. The method has simple extraction technique and low cost, and can process the Enteromorpha in large scale in a short time; the various Enteromorpha seaweed fertilizers produced by taking the fermentation liquid as the material can greatly increase the coldness resistance, drought resistance and stress resistance of crops, reduce plant diseases and insect pests, promote the growing of root system, make the soil to breathe freely and loosen, and greatly improve the crop output and quality, more importantly, the seaweed fertilizer does not produe any bad effect and pollution to crops, environments and human beings, which is a novel green environmental friendly fertilizer for modern agriculture.
