Description

Melon powdery mildew nano titanium and biological sulfur zinc manganese mixture

Technical field

The invention relates to a melon powdery mildew nano titanium and a biological sulfur zinc manganese mixture, belonging to the technical field of agricultural biological plant disease prevention.

Background technique

In the cultivation of melons, especially in the planting environment of greenhouses, due to improper control of temperature and humidity in greenhouses, the elements of nitrogen, phosphorus and potassium are emphasized in fertilization, and the use of zinc, manganese, magnesium and boron in trace elements is ignored. In addition to improper irrigation, melons grown in greenhouses have poor resistance to stress, coupled with improper environmental management, which is suitable for the growth of pathogens of melon powdery mildew. Melon powdery mildew is in the whole process of crop growth, as long as the environment Appropriate disease can occur, especially in the late spring and early summer, late summer and early autumn, the most likely to cause powdery mildew, powdery mildew mainly harms the leaves and stems of crops, although it is not easy to cause crop death, but when the mildew is serious Covering all the leaves, seriously affecting photosynthesis, forming malnutrition of crops, causing premature aging of plants, turning melons, affecting 30-40% of harvest, and even if there are no particles in serious cases, causing serious economic losses, currently used on the market Chemical control methods include ethinyl bacteriophage, methyl thiophanate, chlorothalonil and other chemical agents, which are easy to produce with these chemicals. The residue, soil easy digestion, powdery mildew pathogens resistant to other problems.

Now consumers are paying more and more attention to pollution-free and green foods. The requirements for pesticide residue testing standards are getting higher and higher. How to provide a non-toxic and pollution-free bio-type powdery mildew control agent can not only inhibit melon powdery mildew. It is a kind of solution that is urgently needed in agricultural planting. It can provide micro-element supplement during melon growth, and it does not produce drug resistance after use. It is easy to be absorbed and decomposed by soil and plants.

Summary of the invention

The technical problem to be solved by the present invention is to provide a main component of sulfur, zinc and manganese which decompose sulfur, zinc sulfate and manganese sulfate by photocatalytic oxidation of 60 nm spherical titanium, and then pass through Monascus, Bacillus subtilis and giant spores. Bacillus, Thermophilic Lactobacillus absorbs elements of zinc, manganese and sulfur, which are converted into biotypes of zinc, manganese and sulfur. The sensitive properties of powdery mildew pathogens to zinc, manganese and sulfur are applied. The mechanism of action is 60nm. The forbidden band electrolysis of the spherical polymerized titanium generates heat, damages the cell membrane of the powdery mildew pathogen, applies the sensitive characteristics of the powdery mildew pathogen to zinc, manganese and sulfur, and brings the components of zinc, manganese and sulfur into the cells of the pathogen, destroying Active enzyme conversion of pathogens, thereby inhibiting the growth of pathogens of powdery mildew, and effectively inhibiting the occurrence of powdery mildew. The present invention not only does not pollute the environment, the components used are nutrients required by plants, and are easily degraded in nature, not only inhibiting white powder. The onset of the disease can increase the sweetness and taste of the melon fruit, which is a biological control that can become an economic value. To address pesticide residue and pathogen resistance technical difficulties question.

The technical solution adopted by the present invention to solve the above technical problem is a melon powdery mildew nano titanium and a biological sulfur zinc manganese mixture, the material ratio and process steps are as follows:

1. Material:

(1) Material I: 35% of 60nm spherical polymerized titanium, 15% of sulfur powder, 20% of zinc sulfate, 25% of manganese sulfate, and 5% of chitin:

(2) Material II: one part of Monascus, one part of Bacillus subtilis, one part of Bacillus megaterium, one part of thermophilic lactobacillus, and one part of 25% brown sugar water;

2. Process steps:

(1), sulfur powder, zinc sulfate, manganese sulfate dissolved in 60nm spherical titanium, dissolved in sunlight, photocatalytic decomposition of 2.5h;

(2), the microorganisms in the material II are placed in brown sugar water for enrichment culture for 3d;

(3), the output after the completion of step 1, is put into the fermenter of step 2, and then added chitin in material I, for secondary fermentation, the fermentation period is 7d;

(4) After the fermentation is completed, the residue is filtered to obtain a melon powdery mildew nano titanium and a biological sulfur zinc manganese mixture.

Advantages of the invention:

Compared with the prior art, the present invention has the following effects: the present invention provides an inorganic compound which is photocatalyzed by 60 nm spherically polymerized titanium to form ionic sulfur, zinc and manganese elements, and then utilizes Monascus and Bacillus subtilis. Bacillus megaterium absorbs ionic elements and produces bio-type compounds of sulfur, zinc and manganese. Chitin is converted into a high-lipid membrane by microbial enzymes to polymerize various trace elements. Sprayed on the leaf surface of melon, not only forms a protective film on the leaf surface, the pathogen that isolates powdery mildew is adsorbed on the leaf surface, and has sulfur, zinc and manganese elements sensitive to the pathogen of powdery mildew, when the pathogen is adsorbed. On the leaves, the nanospheres polymerize titanium to produce electrolysis and high heat, destroying the cell membrane of the pathogen, invading the cytoplasm of the element sensitive to the pathogen of powdery mildew, destroying the active enzyme of the pathogen, thereby inactivating the growth of the pathogen of powdery mildew, and additionally The element is a sweetening element of melon, which increases the sweetness quality of the commercial fruit. The material used in the present invention is suitable for large-scale popularization and application after photocatalytic decomposition.
