Description
Technical Field
The invention belongs to the field of plant disease prevention and control, and particularly relates to a special water-soluble fertilizer for delaying the decline of a Huanglongbing tree body and preparation and application methods thereof.
Background
Citrus is one of the most economically valuable and widely cultivated fruits in the world. China is the most prominent citrus producing area in the world. However, in recent years, orchard soil quality has been drastically reduced due to improper fertilization and improper agricultural management measures. Deterioration of soil quality environment leads to a decrease in plant disease resistance and outbreak of Huanglongbing (HLB), with a significant decrease in citrus yield and quality.
Citrus huanglongbing (Citrus huanganglingbin), the most harmful Citrus disease in the world, causes enormous losses to the Citrus industry. It is called "cancer" of citrus, and at present, it has endangered the vast major citrus producing areas of our country, such as the major citrus producing areas of florida, california, paul, and the like. Mainly harms major types and types of citrus, tangerine, orange, lemon, pomelo and the like. Particularly, the disease can be caused all the year round by weak disease resistance of banana oranges, sugar oranges, ponkan oranges, Fortunella oranges, tea branch oranges and other varieties, the disease-induced varieties generally have the symptoms of uniform yellowing, mottled yellowing and element-deficiency yellowing, part of the tops of a few branches of an adult tree often yellow in the whole orange garden, and the yellowing branches expand to the whole tree in the second year, so that the tree body is declined. The fruits born by the diseased trees are small, have strange and different shapes, have inclined umbilicus, have smooth and lusterless epidermis and sour taste, have uneven yellow-green color on the epidermis and become orange-red near the pedicles of some varieties, thereby influencing the yield of the citrus, and are called as 'red nose fruit'. The disease has great harm to citrus production, the disease-susceptible varieties lose fruiting capacity and even die within 3-5 years after the disease is found, in recent years, the disease area is continuously enlarged, the bacterial source area is continuously increased, the epidemic situation diffusion speed is continuously improved, the damage loss is very serious, and the disease becomes a large destructive disease for citrus production.
HLB is a bacterial disease caused by the gram-negative bacterium "Candidatus Liberibacter asiaticus" which is parasitic in plant phloem tissue, diaphorina citri being the main vector of transmission. HLB reduces transport of the photosynthetic products, and accumulation of the photosynthetic products affects the flow of other nutrients, resulting in inhibition of citrus growth. The occurrence of citrus HLB is associated with a number of factors. The microbiota associated with plants can directly or indirectly influence the resistance diversity and stability of citrus towards HLB by changing microbial species, which play a crucial role in various physiological and biochemical processes. In addition, the mineral nutrition balance in the plant can improve the resistance of the plant to the adverse environment. Different citrus varieties have different stress resistance, and some citrus varieties have stronger resistance to HLB. In addition, climate and environmental conditions of citrus plantation can affect the spread of HLB. To date, the main strategies for HLB control are the excavation of diseased trees, chemical pesticides, hybridization and transgenic technologies, and also bring about a series of problems, such as environmental pollution, long cycle and high cost. Therefore, there is an urgent need to find an environmentally friendly and practical method for preventing HLB. Macronutrients and micronutrients are irreplaceable for plant growth, some of which are beneficial for the prevention of plant diseases, and they play a role in activating the plant immune system by altering microbial community structures and metabolic pathways.
The straw vinegar liquid is a byproduct generated in the process of preparing biochar from crop straws, is widely applied to various fields of agriculture, can be used as a soil conditioner and a plant growth regulator, and can replace a synthetic pesticide for preventing and treating plant diseases and insect pests.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a special water-soluble fertilizer for delaying the decline of the body of a Huanglong disease tree, which specifically adopts the following technical scheme:
a special water-soluble fertilizer for delaying the decline of a Huanglong disease tree body comprises the following raw materials in parts by weight: 3-5.5 parts of ammonium polyphosphate, 7.0-12 parts of ammonium nitrate phosphorus, 13-22 parts of potassium nitrate, 7.5-13.5 parts of ammonium sulfate, 0.8-1.5 parts of urea, 10.5-18 parts of EDTA chelated calcium, 12-21 parts of calcium magnesium nitrate, 3.5-7 parts of citric acid and 400 parts of straw vinegar liquid; the solid content of the straw vinegar liquid is more than or equal to 15 percent.
The existing research shows that the straw vinegar has obvious inhibition effect on various pathogenic bacteria such as candida albicans, candida tropicalis, aspergillus niger, escherichia coli, staphylococcus aureus and the like. But does not find a relevant report that the straw vinegar has a killing or inhibiting effect on the yellow dragon disease germs, and after the intensive research of the inventor, the inventor finds that the quantity of the yellow dragon disease germs in the root system can be obviously reduced when the solid content of the straw vinegar is more than or equal to 15 percent, and on the basis, the inventor designs the special water soluble fertilizer for delaying the decline of the yellow dragon disease tree body. Wherein the straw vinegar liquid can be rice straw vinegar liquid, wheat straw vinegar liquid, corn straw vinegar liquid or rice husk vinegar liquid.
Preferably, the raw materials of the special water-soluble fertilizer also comprise 1.3-2.5 parts of EDTA chelated manganese and 1.5-3 parts of manganese sulfate monohydrate. In the onset period of the huanglongbing, the huanglongbing trees such as citrus and the like can show some symptoms of nutrient deficiency, so that some of the technicians in the prior art can supplement nutrition for the direct purpose of supplementing corresponding nutrient elements to relieve the symptoms, which is substantially similar to 'treating symptoms and not treating the root causes'. The inventor deeply knows that the cause of the huanglongbing is the gram negative bacterium 'Candidatus Liberibacter asiaticus' parasitizing in the plant phloem tissue, so that the inventor deeply studies how to inhibit or limit the huanglongbing germs, and finds that when excessive Mn element (more than 3 times of the general dosage) is added, the number of the huanglongbing germs in the root system of the citrus can be well inhibited, the effect of delaying the decay of the huanglongbing tree body is realized, and the 'root cause control' is carried out to a certain extent. Meanwhile, on the basis of adding excessive Mn element, if the amount of NPK is reduced to a certain extent (30-50% less than the ordinary amount) for matching, the reduction of the number of the yellow dragon germs in the citrus root system is more obvious. On the basis, the inventor compounds the discovery of the compound fertilizer with straw vinegar liquid, so that the inhibition effect on the yellow dragon disease germs in the root system is further enhanced, compared with the method of singly applying excessive Mn element, the compounded special water soluble fertilizer has quicker effect, the yellow dragon disease germs in the root system can be enabled to be negative in the second year of application, the tree vigor is obviously recovered, and the high yield and the high quality are realized.
Preferably, the raw material of the special water-soluble fertilizer also comprises 0.25-0.5 part of boron. The inventor also finds that the addition of the element B can well inhibit the quantity of yellow dragon disease germs in the scions.
Preferably, the raw materials of the special water soluble fertilizer also comprise 0.2-0.4 part of EDTA chelated copper, 6-10.5 parts of EDTA chelated iron, 0.01-0.02 part of ammonium molybdate heptahydrate, 3.5-6 parts of EDTA chelated zinc, 0.5-2 parts of triclocarban and 2-3.5 parts of solubilizer. After the trace elements such as iron, zinc, copper, molybdenum and the like are supplemented and the triclocarban is used as an auxiliary bactericide, the effect is further improved; the yellow dragon disease tree body can be negative in the first year, the tree vigor is remarkably recovered, and high yield and high quality are realized in the current year. Wherein, the solubilizer can be AEO, polyethylene glycol or TX-10 and other nonionic surfactants.
The preparation method of the special water-soluble fertilizer comprises the following steps:
(1) dissolving ammonium polyphosphate, ammonium phosphate nitrate, potassium nitrate, ammonium sulfate, urea, EDTA chelated calcium, calcium magnesium nitrate, citric acid, supported boron, EDTA chelated copper, EDTA chelated iron, EDTA chelated manganese, EDTA chelated zinc, manganese sulfate monohydrate and ammonium molybdate in the straw vinegar liquid;
(2) dissolving triclocarban in a solubilizer, dissolving the triclocarban in the solution obtained in the step (1) under the condition of stirring, and filtering to obtain the triclocarban.
The application method of the special water-soluble fertilizer comprises the following specific steps: fertilizing once every 15-20 days beginning in 1 month every year, wherein the application standard is 0.5-3kg per plant; the fertilization times are at least 8 times before the fruit expanding period.
The special water-soluble fertilizer and the application method thereof are suitable for oranges, Nanfeng tangerines and navel oranges.
The beneficial effects of the invention are as follows: the invention discovers that the straw vinegar liquid with the solid content of more than or equal to 15 percent can reduce the quantity of the Huanglongbing germs in the root system, and the special water-soluble fertilizer designed based on the discovery can well achieve the effect of 'curing root causes' and delay the decline of the Huanglongbing trees. Compared with the conventional water-soluble fertilizer special for citrus, the water-soluble fertilizer special for citrus prepared by the invention has the advantages that on the basis of pyroligneous liquor, a large amount of nutrient elements such as manganese, boron and zinc are added, and an auxiliary bactericide triclocarban is added, so that the content of citrus tree yellow shoot germs can be effectively reduced by continuous and repeated application, the symptoms of yellow shoot are greatly relieved, the root growth is promoted, and the tree vigor is obviously recovered.
