A modeling framework for estimating crop growth and development over the course of an entire growing season generates a continuing profile of crop development from any point prior to and during a growing season until a crop maturity date is reached. The modeling framework applies extended range weather forecasts and remotely-sensed imagery to improve crop growth and development estimation, validation and projection. Output from the profile of crop development profile generates a combination of data for use in auxiliary farm management applications.

The invention relates to a carbon-based fertilizer potentiating agent and application of the carbon-based fertilizer potentiating agent. The carbon-based fertilizer potentiating agent is characterized by comprising the raw materials in proportion by weight: 50-70 carbon powder, 5-15 humic acid, 2-5 inhibitors mixing urease inhibitor with nitrification inhibitor, 10-20 microelement fertilizer, and 5-10 acid bentonite or clay; biomass granule carbon is selected as a matrix carrier, the production process is simple, raw materials are easily obtained, and the cost is low. The biomass carbon has strong adsorbability, water retention property and light absorption warming property, and can be used as good ammonia stabilizer and soil conditioner except for the carrier. After being applied into soil, the potentiating agent can lead the fertilizer to slowly release, and can relieve the influence of drought and lacked water and low temperature on crop growth. The potentiating agent not only can improve the fertilizer utilization rate, but also is environment-friendly and safe, can effectively improve the utilization rate of nitrogenous fertilizer and phosphate fertilizer, reduce fertilizer loss, and simultaneously can lighten the water body pollution and greenhouse effect by nitrogenous fertilizer, reduce the content of nitrate nitrogen in agricultural products, and ensure the safety production of food.

An apparatus for growing vine crops in a greenhouse comprises a first media carrier, a first nutrient supply means, a first support means, a regulating mechanism, a main cable, a plurality of load differential mechanisms, a second media carrier, a second nutrient supply means, and a second support means. The second media carrier is above and in substantial parallel with the first media carrier. The distance between the first media carrier and second media carrier is adjusted by the regulating mechanism. A method for growing vine crops in a greenhouse comprises two growing modes: a single crop growing mode, and a vertical dual crop growing mode. The sequence of this process begins with a first single crop growing mode, followed by a vertical dual crop growing mode, and then followed by a second single crop growing mode. A single crop growing mode: first crops grow in the first media carrier fed by the first nutrient supply means, trained by the first support means. A vertical dual crop growing mode: the first crops grow in the first media carrier fed by the first nutrient supply means trained by the first support means; and second crops grow in the second media carrier above the first media carrier fed by the second nutrient supply means and trained by the second support means.

The invention discloses an automatic observation device for crop development and growth. The device comprises an image acquisition part, a communication transmission system and a data processing centre, wherein the image acquisition part comprises a CCD camera, a video monitor and a lightning conductor which are fixed with a bracket; the bracket is arranged in a crop planting area; an antenna fixed to the top end of the bracket is in wireless connection with a computer which receives and processes the data of the crop development and growth and is arranged in a data processing centre through a wireless network; the communication transmission system comprises antennae and encoders respectively positioned on the image acquisition part and the two ends of the data processing centre; and the computer in the data processing centre comprises an image database, an image feature algorithm library and a product library. The device performs real-time automatic acquisition and identification on crop growth information, performs long-term observation, analysis and measurement remotely through a network, automatically measures aiming at the crop growth, has a simple measurement principle and an accurate measurement result, is convenient to popularize and use, and has significance to promote the modernization and the automation of agricultural meteorological observation.
