In an embodiment, autonomous vehicles with global positioning systems (GPS) are used for field inspection to reduce fuel and labor costs and improve reliability with increased consistency in field crop inspection. A vehicle may be programmed to traverse a field while using sensors to detect objects and operating in a first image capture mode, for example, capturing low-resolution images of objects in the field, typically crops. Under program control, machine vision techniques are used with the low-resolution images to recognize crops, non-crop plant material or undefined objects. Under program control, location data is used to correlate recognized objects with digitally stored field maps to resolve whether a particular object is in a location at which crop planting is expected or not expected. Under program control, depending on whether an object in a low-resolution digital image is recognized as a crop, and whether the object is in an expected geo-location for crops, the vehicle may cease traversing temporarily and switch to a second image capture mode, for example, capturing a high-resolution image of the object, for use in disease analysis or classification, weed analysis or classification, alert notifications or other messages, or other processing. In this manner, a field may be rapidly traversed and imaged using coarse-level, rapid techniques that require lower processing resources, storage or memory, while automatically switching to execute special processing only when necessary to resolve unexpected objects or to perform operations such as disease classification that benefit from high-resolution images and more intensive use of processing resources, storage or memory.

The embodiment of this specification provides a credit line processing method and device, and a user resource processing method and device, wherein, a credit line processing method includes: obtaining the identity information entered by the target user and the plot information of the crop plot; The target user displays the map page; if the labeling action input on the map page is detected, the plot boundary information corresponding to the labeling action is determined; the labeling area of ​​the crop plot is calculated based on the plot boundary information; according to the Determine the credit line of the target user based on the marked area, the land plot information, and the user data obtained based on the identity information.

The invention provides a method for recommending the amount of fertilization of crops. On a plot, according to the known planting information of the plot, including the parameters related to the crops and fertilizers of the plot, the unit area of ​​the crops to be planted is obtained According to the balance value of nitrogen, phosphorus and potassium nutrients, the amount of nitrogen, phosphorus and potassium nutrients used for planting crops is recommended. The method of the present invention overcomes the unfavorable factors such as long cycle and high cost of traditional soil testing and fertilization, and recommends fertilization through the nutrient input-output balance of customary fertilization without measuring soil or plant nutrient content, which is easy to operate and popularize , low cost and other characteristics, it is a scientific and precise multi-balanced fertilization method.

The invention discloses a liquid preparation produced by the utilization of livestock and poultry breeding wastewater and an application of the liquid preparation in controlling and eliminating continuous cropping obstacles. The liquid preparation is prepared from bacillus subtilis D9 and Trichoderma asperellum 12 fermentation livestock and poultry breeding wastewater. Total microorganism amount in the liquid preparation is greater than 10*10<8>cfu ml<-1>. Effective functional microorganism colony-forming unit is greater than or equal to 0.5*10<7>cfu ml<-1>. Content of bacillus subtilis D9 is greater than 0.5*10<7> cfu ml<-1>. Content of Trichoderma asperellum 12 is greater than 0.1*10<6> cfu ml<-1>. Amount of biocontrol microorganisms around rhizosphere of seedlings of cutting tissue or transplanted crops, pathogen-infected cutting tissue or transplant seedlings in continuous cropping soil are minimized, continuous cropping obstacles are effectively controlled and eliminated, and a lot of breeding wastewater can be consumed. It shows through tests that incidence of disease is reduced by 93.8% after the production is applied on artemisia seleirgensis continuous cropping obstacle soil; 5-8 tons of breeding wastewater can be consumed per mu of artemisia seleirgensis continuous cropping land; and incidence of disease is reduced by 87.3% after the production is applied on tomato continuous cropping soil, and 10-20 tons of breeding wastewater can be consumed per mu of tomato planting land.

The invention provides stubble-pushing row-cleaning, rotary tillage and sowing technology for corns, pertaining to the technical field of crop cultivation. The stubble-pushing row-cleaning, rotary tillage and sowing technology is characterized in that in a previous crop land parcel where straw is accumulated, stubble-pushing and row-cleaning, deep fertilizing, single-grain precise sowing operation are carried out within rows of sowing belts; in association with water spraying and medicine-spraying operation, multiple operation processes such as deep-rotating, soil-loosening and straw mulching are performed among sowing belts and are completely one time mechanically. The stubble-pushing and row-cleaning technology is performed in such a manner that preceding straw are cut off and crushed at seeding strips and pushed out of sowing belts to stay at non-sowing belts; and meanwhile, shallow rotary tillage at the depth of approximate 10 cm is performed in form seeding strips in sowing belts having no straw or few straw and loose surface soil. The stubble-pushing, row-cleaning, rotary tillage and sowing technology for corns has following beneficial effects: due to the fact that stubble-pushing and row-cleaning operation is used in conjunction with technology such as deep rotary tillage, deep fertilizing and precision sowing, simplified and highly-efficient plantation technology featuring low power consumption and high yield of corns is formed so that difficulties for corn production such as accumulation of preceding straw, poor sowing quality, a solid plow sole of a plough layer and low populations uniformity are effectively solved.
