5 results about "Soil fertility" patented technology

The invention relates to the field of fertilizers, in particular to a high concentration anti-disease compound microbial bacterial fertilizer and a production method. The effective viable count of thefertilizer is greater than or equal to 5*10<9> (5 billions)/ml, and each of bacteria is not lower than 0.3 billion/ml; the bacterial strain is bailipenicillium, bacillus subtilis, bacillus megatherium, trichoderma sp, Burkholderia cenocepacia and PGRP. The fertilizer has the advantages of improving the soil physical and chemical properties, enhancing soil fertility, assisting plants to absorb nutrients, enhancing the anti-disease and anti-drought abilities of plants, improving the environmental pollution, saving the energy sources, lowering the production cost and the like. The effective viable count of the high concentration anti-disease compound microbial bacterial fertilizer is kept above 5 billions/ml, thereby providing high concentration raw material bacterial liquor to production ofsolid bacterial microbial bacterial fertilizes and compound fertilizers.

The invention relates to a multifunctional fertilizer for preventing and treating open rice glumes. 25-35 parts of decomposed manure, 5-15 parts of humic acid, 2-10 parts of fulvic acid, 2-15 parts of magnesium sulfate, 2-15 parts of chelated zinc, 2-8 parts of Na2B8O13 and 5-15 parts of calcium metasilicate are smashed and screened by a 60-mesh screen, then the mixture is placed in a stirrer to be fully stirred, then 5-20 parts of amino acid powder, 1-5 parts of tillering promoter, 1-5 parts of stem strengthening agent and 0.5-2 parts of ABB pollenin are added, and even mixing and packaging are carried out. Based on the reason for the open rice glumes, organic nitrogen, phosphorus, potassium, multiple microelements, active matter and functional factors are supplemented, the open rice glumes can be effectively prevented and treated, rice resistance can be increased, and the maturing rate and yield can be increased. Multiple organic ingredients are included, the content of organic matter of soil can be increased, soil environment can be improved, soil fertility can be improved, rice tillering can be promoted, resistance and the maturing rate can be increased, and the aim of increasing both production and income is achieved.

The invention relates to a control method for bacterial blight of rice. The control method comprises the following steps: 1, ecological management: applying HYT (high yield technology) or Difulai microorganism fertilizer so as to improve soil physical and chemical properties, improve soil fertility and enhance the absorbing ability of rice roots; 2, agricultural control; 3, biological control; 4, biological prevention; 5, physical control; 6, chemical control: spraying 20 percent of bismerthiazol, 10 percent of chloramphenicol, 70 percent of phenazin or 25 percent of Yekuling wettable powder after a center disease plant is discovered. The bacterial blight of the rice can be effectively controlled; meanwhile, integrated control is performed by adopting measures of the agricultural control, the physical control and the like so as to reduce the average incidence of the bacterial blight of the rice, therefore the yield is increased; the grade of the rice is obviously increased; good economic benefit is obtained.
