The invention discloses anti-continuous cropping and continuous cropping fertilizer and a production method, bacterial fertilizer is composed of the bacterial liquid of azotobacter chroococcus, bacillus cereus and silicate bacteria and carrier, trace fertilizer is composed of borax, ammonium molybdate, zinc sulfate, SiO2, CaO, MgO and carrier, and then the bacterial fertilizer and the trace fertilizer are mixed to produce the fertilizer. The invention as the bio-enzyme preparation has no side effect of toxicity and can effectively resolve the problems of the continuous cropping harm and continuous cropping barrier of crops. The invention has a specific effect on resolving the salinization and sub-salinization of soil in a greenhouse and can regulate the abilities of nutrient absorption and disease resistance of soil. The invention can effectively restrain the growth of harmful pathogens, such as soil nematodes, etc. and rapidly promote the propagation of beneficial microorganisms. The invention can promote the rootage of plants and increase the survival rate of seedlings. The invention perfectly resolves problems of the continuous cropping harm and low yields of manifold crops, such as corn, paddy, soybean, coarse cereals, vegetables, etc.

The invention relates to a microbial fertilizer granule which comprises a core layer and a coating layer, wherein the core layer comprises the following materials in parts by weight: 4-8 parts of crushed straws, 2-6 parts of crushed wood chips, 10-12 parts of clay and two strains of each of cellulose degradation bacteria, azotobacteria and phosphate solubilizing bacteria, which are uniformly mixed, wherein the quantity of each strain is more than 1*(10<5>-10<6>) in every gram of core layer mixture; and the coating layer is formed by drying 3%-6wt% of a gelatin solution coating the outer side of the core layer in the shade. The invention also relates to a preparation method of the microbial fertilizer granule and a corresponding microbial fertilizer granule carrier. The microbial fertilizer granule disclosed by the invention overcomes the defect of the traditional microbial fertilizer that microbes cannot be stably colonized in soil and is capable of profitably recycling waste biological materials which are difficult to dispose in agricultural production.

The invention discloses a compound fermented feed for dairy cows, its preparation method and application, and belongs to the technical field of biological fermented feed. The compound fermented feed for dairy cows of the present invention is composed of the following components in parts by weight: 20-30 parts of rice husk, 46-68 parts of fermented peanut meal, 50-70 parts of ammoniated corn stalks, and 10-18 parts of fermented algae powder , Chitosan oligosaccharide 2-5 parts, oyster powder 2-4 parts, medical stone powder 2-4 parts. The reasonable combination of components of the compound fermented feed for dairy cows of the present invention can not only increase the milk production of dairy cows, but also improve the nutritional quality of the produced milk; Improve the digestion of nutrients, increase the body's ability to absorb calcium and phosphorus, and enhance nitrogen metabolism.

The invention particularly provides a heating-free granulation production method of humic acid, aiming at solving the problems of an existing granulation technology that the strength of humic acid particles is not enough, and the energy consumption of granulation is high. The heating-free granulation production method of the humic acid comprises the following steps: after uniformly mixing and stirring humic acid powder, ammonium sulfate powder and urea powder according to the ratio of (92.5 to 94) to (5 to 6.5) to 1, adding the mixture into a granulation machine; atomizing water which accountsfor 29 percent to 32 percent of the total weight of the materials, and spraying the water on the surfaces of the materials; mixing and granulating at a rotary speed of 27r / min to 43r / min to obtain the humic acid particles; after staying in a room-temperature conveying system for 20min to 50min, sieving finished-product humic acid particles with the grain diameter of 2mm to 4mm through a multi-grade sieving device. According to the heating-free granulation production method of the humic acid, an additive is cheap and easy to obtain, the production cost is low, and technological conditions aresimple; the problem that the strength of humic acid particles is not enough is effectively improved; when the humic acid is applied to soil, a soil granular structure can be improved; the humic acid can be widely popularized and applied to the technical field of agriculture.

The invention relates to a protective farming and cultivating method, which is characterized in that a bisection crop-grass intercropping subsoiling straw-returning technology is employed, namely, a small ridge of 70 cm is employed; crops and leguminous forages are intercropped, so that a seedling region and a leguminous forage region are formed; two-row bunch planting is employed in the seedling region; proper close planting can be employed in the seedling region; a pitch is 20-25 cm; two rows of the crops are planted at intervals; the crops are planted in a triangle manner. According to the protective farming and cultivating method, a bisection method is employed for translation every year; the crops and the leguminous forages are intercropped in the first year; straws are all applied into the seedling region after harvesting, the straws are mulched; the crops are planted in the previous leguminous forage region in the second year; the leguminous forages are planted in the previous seedling region in the first year; the crops are not planted in the region in which the straws are applied; after the straws are thoroughly decomposed for one year, the crops are planted, so that the influence of the current-year straw returning on the crop yield is prevented, and the complete straw returning treatment of soil can be realized within two years.

As disadvantages of chemical nitrogen production and a large number of used chemical fertilizers become increasingly obvious and the effect of increasing yield becomes increasingly unobvious, the invention provides a biological nitrogen production method. The core of the method is that: according to the characteristics of different nitrogen-fixing microorganisms, the relation between the different nitrogen-fixing microorganisms and plants, different living conditions of the different nitrogen-fixing microorganisms and the plants, and the mechanism principle and related scientific theories of biological nitrogen fixation, and by various measures, systematic coordination, overall cooperation and combined action, the nitrogen-fixing microorganism in soil are cultured and increased, and the nitrogen fixing capacity of the nitrogen-fixing microorganisms is improved; and the nitrogen-fixing microorganisms are used to produce nitrogenous fertilizers so as to meet the requirement of plant growth on nitrogen. The method has the advantages of capacity of continuously reducing the using amount of the chemical fertilizers, gradually recovering and improving soil fertility, improving the stress resistance and quality of crops and saving resources, environmental-friendliness, circular replaceability and sustainable development.
