1. Self-toxicity: The crop itself produces waste and excretion becomes toxins around the roots. Accumulation of more and more is not conducive to growth and development. It poisons itself. This is called self-harm poisoning. Detoxification measures: 1 round of dumping; 2 wood grafting; 3 organic fertilizer used bacterial fermentation; 4 with Wuyi bacteria root, toxins.
2. Soil-borne diseases: Because of heavy worms, soil-borne pathogens accumulate and cause rot. Measures for prevention and control of soil-borne diseases: 1 round of dumping; 2 wood grafting; 3 large shed vegetables sterilized in high temperature season; 4 mixed with hymexazol, thiram, and Prec, and can kill all soil-borne pathogens But at the same time killing the beneficial bacteria, it is not the best way; 5 It is best to use Wuyi bacteria to irrigate the soil-borne pathogen. 6 Use of plant vaccines: There are some free radicals in plant cells. These free radicals are not harmful, but when the bacteria invade the cells, these free radicals are like traitors to rot cells from inside and cause plant diseases. Plant vaccines can clean these traitor free radicals from the cells, and when the plants are attacked by bacteria, they can produce resistance, reduce the disease, and even stop developing. The use of plant vaccines can not only prevent diseases caused by double crops, but also prevent and control various diseases such as viral bacteria and fungi, reduce the use of drugs, and even eliminate the use of drugs. Therefore, someone evaluated the plant vaccine: As long as the plants are green, they can be revived.
3. Nematode Hazards: Unfamiliar organic matter contains nematodes, which accumulate as they become heavy. Measures to control nematodes: 1 Fertilizer fermentation of organic fertilizer; 2 irrigation of water for several days, suffocation and dying of nematodes; 3 currently made nematicides is abamectin.
4. Unbalanced fertilization; This is the most important cause of severe planthopper disease, and is more serious than self-toxicity, soil-borne diseases, and nematode damage. Why is fertilization unbalanced? It is because the farmers are confused. 1Bewildered by experts: Experts have been shouting attention to phosphorus and potassium fertilizers in lectures, in technical guidance, and in writing writing papers, so farmers listened to experts and then re-applied phosphorus and potassium fertilizers. As a result, phosphorus was excessive and the trace elements were fixed. As a result, a variety of deficiency certificates have emerged, and the bacteria have been able to enter the country. This has led to the occurrence of various diseases. Farmers have a large number of pesticides to cure diseases, thus creating a vicious circle. Phosphorus deficiency and the lack of trace elements are the culprits of heavy scorpion; 2 manufacturers confused with phosphorus and nitrogen and potassium can be blended, but not with calcium, magnesium, iron, zinc, manganese, copper blend, if blended when fertilizing, then you must With organic fertilizer and biological bacteria. Some manufacturers have launched a full-yuan compound fertilizer, which is clearly cheating on the ignorance of the people; 3 being confused by the soil measuring instruments: phosphorus-containing fertilizers are soon applied to the soil, and soon there are 80% or so and most trace elements. Combined together, it is fixed in the soil, and when the organic fertilizer and the biological bacteria are applied, these fixed phosphorus will be released again, so that phosphorus cannot be applied more. However, the soil testing instruments cannot measure these fixed phosphorus and can only measure soluble available phosphorus. Fertilizer can easily lead to excess phosphorus if determined as a result of the determination. Phosphorus excess will inevitably cause trace elements to be fixed and cause heavy smashing. Therefore, peasant friends should not superstition earth measuring instruments.
Balanced fertilization
1. The introduction of biological bacteria: there are many kinds of biological bacteria. Commonly used biological bacteria are antibiotics and complex bacteria. These biological bacteria decompose and release fixed phosphorus and potassium, trace elements, and eat soil-borne pathogens and toxins. Stimulate plant growth.
2. Application of nitrogen, phosphorus, and potassium fertilizers: Phosphorus is not required for plants. After potassium, nitrogen, silicon, and calcium, it is sometimes less than magnesium. Therefore, a farmer friend should apply 16-8-16 NPK fertilizer. Then, according to the needs of the plant, apply urea and potassium sulfate again, and when the plants are weak, adjust them with urea.
3. The application of medium and small fertilizers: The plant lacks medium and micro-fertilizers, and must suffer from heavy caries. The medium-, micro-, and micro-elements are made up of elements such as magnesium, iron, zinc, copper, and boron in proportion. Farmers generally buy incompletely and they are not matched. Therefore, the farmers' friends can directly use the fertilization formula with reasonable formulas. The content of various nutrient components is formulated according to the crop growth and can meet the normal growth requirements of crops.
4. Application of calcium fertilizer: Calcium is one of medium and small fertilizers, but calcium should not be mixed with other fertilizers, but should be applied alone. Plants need a lot of calcium, and calcium can bury the soil structure, so it should be a lot of calcium. Regardless of soluble calcium, or insoluble calcium, enter the soil into semi-dissolved calcium, so farmers do not have to buy high-speed instant calcium. Neutral or acidic soil is used to spread lime 50 kg/mu, and alkaline soil is applied to plaster 100 kg/mu.
5. Application of Organic Fertilizer: Organic fertilizer can improve the soil, protect the animal's fertilizer and water, increase the temperature of the soil, provide various nutrient elements for the plants, produce a large amount of carbon dioxide in the greenhouse, and also help the propagation of the biological bacteria, and fix the phosphorus and potassium that has already been fixed. The trace elements are released again. The organic fertilizer is blended with the medium and micro-fertilizers and used as a base fertilizer.
