The invention discloses a double-layer straw mulch-laying machine for an orchard and relates to the field of orchard machines. A trailer provided with a straw box is pulled by a tractor, a discharging roller is arranged on the bottom of the front portion of the interior of the straw box, a straw discharging outlet under the straw box is connected with a straw distributing pipe, a soil throwing device is hinged to the tractor and located below the straw distributing pipe, a soil throwing port of the soil throwing device inclines upwards and backwards and located below an outlet of the straw distributing pipe, the direction of the soil throwing port intersects with the direction of the outlet of the straw distributing pipe, the soil throwing device can rise and fall under the action of a lifting oil cylinder, and the straw box can tip forwards under the action of a dump oil cylinder. The machine can mulch the ground between the lines of the orchard with straw and cover the straw layer with thin soil, is suitable for conducting mechanical straw mulching in the orchard or other farmland areas, can achieve soil moisture retention, water saving, weed suppression, soil organic matter increasing, heat preservation, freezing prevention, soil texture improvement and soil microenvironment improvement, and is especially suitable for dwarf-stock orchards. By the adoption of the machine, straw mulching cost can be reduced, scale utilization of straw can be promoted, agriculture income increase is achieved, and efficiency is improved.

The invention discloses a method for improving a saline and alkaline land by utilizing alfalfa-beet-cotton-maize rotation. By the method, the saline and alkaline land is improved by ditching and draining, pressing salt into fresh water, adding improved fertilizer or compound fertilizer, performing ploughing and rotary tillage, planting alfalfa, beet, cotton and maize year by year and returning straws. The method has prominent improvement effect on the whole saline and alkaline land, and the improvement process is environment-friendly and pollution-free. Therefore, the method is an applicationtechnology worthy of large-area popularization.

The invention discloses a straw unbundling and spreading method and an orchard straw mulching machine, and belongs to the technical field of orchard machinery. Straw bales of different shapes are unbundled, combed and impacted, so that combed loosened straw can be continuously, uniformly and quantificationally spread among fruit tree lines. The orchard straw mulching machine mainly comprises a compartment, a conveying and stirring device, an unbundling and spreading device, a spraying device and a power device; the inner bottom face of the compartment is provided with the conveying and stirring device, the rear of the inner portion of the compartment is provided with the unbundling and spreading device, and the upper rear of the outer portion of the compartment is provided with the spraying device; the conveying and stirring device and the unbundling and spreading device are both driven by the power device. The method and the orchard straw mulching machine are applied to the orchards in an arid area, and especially suitable for mechanical straw unbundling and mulching work of the orchards, are conductive to unbundling and uniform discharging of straw bales, reduce the straw mulching cost, promote the scaled utilization of straws, are also suitable for discharging of fungi residues, animal manure, organic fertilizers and various agricultural waste, and achieve the improvement ofthe agricultural yield and efficiency.

The invention discloses a preparation method of high efficiency bio-organic fertilizer. The preparation method comprises blending: carrying out matching on bio-organic fertilizer base components such as livestock manure, rice bran, plant straws and peanut hulls according to a weight percentage ratio of 50: 10: 30: 10, transporting the base components into a blending workshop and carrying out blending, fermentation: putting the uniformly blended components into an aerobic fermentation pool, adding a microbial agent into the components according to a weight ratio of the microbial agent to the organic fertilizer base of 1: 99, and carrying out high-temperature fermentation, wherein in fermentation, the blended materials in the aerobic fermentation pool are turned periodically at time intervals of 72h so that uniform fermentation is realized, and cooling: carrying out continuous turning and ventilation on the fermented organic fertilizer so that the fermented organic fertilizer is cooled to the normal temperature, feeding the cooled fermented organic fertilizer into a packaging workshop and carrying out packaging to obtain products to be sold. The bio-organic fertilizer is green organic fertilizer, does not pollute the environment and improves disease and insect resistance of crops through use of microorganisms.

The invention discloses a straw crushing granulating machine cooperated with a harvester and a use method of the same. The straw crushing granulating machine cooperated with the harvester comprises crops, the harvester, a straw crushing granulating device, a charging inlet and a discharging outlet. The straw crushing granulating machine cooperated with the harvester is characterized in that the back end of the harvester is provided with the straw crushing granulating device; and the charging port of the straw crushing granulating device is connected with a straw discharging port. The straw crushing granulating machine cooperated with the harvester is advantageous in that when the crop harvester works, produced waste straws can be crushed into powder or granules via the straw crushing granulating device; then the powder or the granules are spread on the field to increase fertility and to improve a soil state; and the powder or granules can be also used for other actions. The straw crushing granulating machine cooperated with the harvester can be conveniently assembled and detached; straws discharged out of a threshing chamber can be crushed, so the straws of the crops after threshed via the harvester can be crushed and returned to the field; highly compound integrated work function can be achieved and next time cultivation on the field can be greatly facilitated; an environment pollution problem due to straw incineration can be solved; and land revenue can be increased for relative recovery companies if the straws are sold.

The invention discloses a saline-alkali soil restoration and finishing method. The saline-alkali soil restoration and finishing method comprises the steps of mechanical deep ploughing of land, upturned soil sunning, salt elimination by underground concealed pipes, further deep ploughing, upturned soil sunning after spraying of prochloraz, application of a base fertilizer and an improved compound fertilizer, film mulching, rotary tillage and the like, wherein the improved compound fertilizer is prepared from desulfurized gypsum, charcoal, zeolite, pyrite, calcium chloride, dry branch and fallenleaf powder, furfural residues, citric acid residues, ferrous acid and a microbial agent. According to the saline-alkali soil restoration and finishing method, the pH value and the salt content of the saline-alkali soil can be remarkably reduced by planting corn after the saline-alkali soil is managed, compared with a traditional soil management method, the saline-alkali soil restoration and finishing method is better in saline-alkali soil restoration and finishing effect, and experiments prove that the soil condition of the saline-alkali soil can be gradually improved after crops are plantedin successive years after the saline-alkali soil restoration and finishing method is used for saline-alkali soil restoration and finishing.

The invention discloses a method for controlling dendrocalamus latiflorus cyrtotrachelus longimanus fabricius. The method comprises the steps of garden cleaning in winter, imago light trapping, manual larva catching and killing, film sleeving and the like, the process is simple, and implementation is easy. The forest culture and management technology is combined, the sanitation and soil conditions of a bamboo garden are improved, overwintering survival data of cyrtotrachelus longimanus fabricius larvas is reduced, the number of imagoes coming out of earth next year is reduced, biological control measures, physical control measures and the like are adopted, the imagoes are caught and killed, the number of the imagoes in the bamboo garden is reducd, the problems of environmental pollution, pesticide residues and the like cannot be caused in the control process, and the needs of consumers for sanitation, health and safety of bamboo shoot products are met.
