A computer system for a pricing and auction process allows private enterprise firms to establish an individual price for each consumer paying in to support delivery of the same units of a public good. The process solicits bids from individuals who value a public good, while reducing each individual's incentives to free ride, thereby increasing their incentives to bid or offer a payment that approaches their full value for each, successive unit of the good. Examples include farmers selling the services of land for wildlife habitat, farmers altering production processes to reduce pesticides and nutrients and increase local water quality, particularly during transition from technologically intensive farming to organic farming, or businesses established to help neighborhoods and communities become carbon neutral in a global economy. The process benefits profit or non-profit organizations supporting conservation such as wetland and salt marsh restoration or restoration of endangered species habitat.

The invention discloses a method for cultivating dryland wheat simply at high yield and high efficiency. The method solves the problems that existing intensive cultivation is high in cost, low and unstable in yield and unsuitable for mechanical cultivation. The method comprises the steps that a, when the wheat is harvested mechanically, high stubble is reserved and returned to the field completely; b, deep ploughing is conducted, and diammonium phosphate fertilizer containing phosphorus pentoxide is applied to the field; c, weeding is conducted after the wheat is harvested and before deep ploughing is conducted; d, coated seeds are selected and used for seeding; e, seeding is conducted when the daily average temperature ranges from 15.5 DEG C to 18.0 DEG C, and the seeding rate ranges from 8.0 kg to 10.0 kg / mu; f, before rotary tillage seeding repression, urea is applied to the field for 16.5-18.5 kg / mu, the rotary tillage depth ranges from 14 cm to 16 cm, the seeding depth ranges from 4 cm to 5 cm, and ridges are made flat through a rake after seeding; g, after seedlings of the wheat emerge, chemical weeding is conducted in time; h, if the soil moisture content is large, ploughing is conducted when the earth surface begins unfreezing, soil is crashed and the field is flattened after ploughing, and soil moisture is preserved ; i, red spiders and wheat aphids are prevented and controlled by means of spraying mist; j, one spraying and three prevention is conducted according to the conditions of diseases and insect pests, and spraying is conducted once again every 10 d; k, in the last dough stage of the wheat, the wheat is harvested mechanically in time. By means of the method, the moisture storage capacity of the soil with the thickness ranging from 0 to 200 cm is increased apparently, and the utilization rate of nitrogenous fertilizer and the utilization rate of phosphate fertilizer in current seasons are increased by 3.58%-5.69% and 1.86%-3.93% respectively.

The invention discloses a net cage ecological algae phase intensive cultivation method for odontobutis obscura. The method comprises the following steps: (1) establishing an intensive cultivation device, arranging a floating bed on a net cage, and planting aquatic vegetables on the floating bed; (2) breeding fish fries outside the net cage; (3) feeding the fries twice every day based on a criterion that the fries are stuffed to prevent residual feeds from polluting water; (4) performing water quality management. In an entire cultivation process, a riverway micro water flow technology is adopted, so that the gonad development of parents can be promoted, a constant incubation temperature is kept for fertilized eggs, hurt or death of the fertilized eggs due to excessively high incubation temperature caused by high density of the fertilized eggs is prevented, and the growth and reproduction of water molds after the death of the fertilized eggs are prevented to avoid influencing the incubation emergence rate of the fertilized eggs. Meanwhile, ecological algae and high-quality riverway water are introduced together into the net cage, so that a food chain is established in the cage, the natural living environment of the odontobutis obscura is simulated, the growth speed of the odontobutis obscura is raised, the yield is increased, and the cultivation quality is improved.

The invention provides a mulberry tree square integrated cultivation method. The mulberry tree square integrated cultivation method comprises the following steps that a mulberry field is divided into cultivation areas and non-cultivation areas, each non-cultivation area is the interval between every two cultivation areas, each cultivation area is square, and the four corners of each cultivation area are mulberry tree planting points; each cultivation area is ploughed deep, fertilization and watering are conducted on the center of each cultivation area, and every time watering is conducted, the mulberry trees are watered thoroughly. According to the mulberry tree square integrated cultivation method, on the condition that the total number of the mulberry trees is not changed, the planting space of the existing mulberry trees is changed, then, the principle of the combination of sparseness and denseness is applied in a matched mode, and therefore the purposes that arrangement is more reasonable, the ventilation and light transmittance conditions are improved, and the photosynthesis of the mulberry trees is improved are achieved. In addition, by the adoption of partial intensive cultivation and centralized trial of efficient slow release fertilizer, the utilization rate of the fertilizer is improved, therefore, the cultivation technologies such as mulberry filed cultivation, mulberry field fertilization and mulberry field management are highly integrated, finally, the mulberry leaf yield is improved, the mulberry leaf quality is improved, the labor intensity is relieved, and the economical benefits of mulberry tree planting are increased.
