Problems solved by technology

[0003] The commonly used method of root irrigation is that one is to directly pour the medicine on the soil surface of the plant root, the penetration of the medicine is poor, the utilization rate is extremely low, and the uniformity of the dosage of the medicine is poor; When dripping water, the medicine is dripped into the root of the plant with the water. Although the dosage of the medicine can be controlled and the use is convenient, the use cost is relatively high, especially for small-area fields where multiple crops are planted, it is necessary to install multiple fixed fertilizer application devices. These devices are not only expensive to use, but also complicated to install and disassemble, resulting in waste of manpower and material resources

[0036]Method of fertilization and fertilization for capsicum root irrigation:

[0037] 1), land preparation: land preparation, base fertilizer application. Apply 3-4 tons of decomposed organic fertilizer per mu, apply 50 kg of compound fertilizer per mu, and 10-15 kg of bacterial fertilizer (Bacillus subtilis) per mu, mix and spread evenly in the soil, plow and harrow and grind to keep the fertilizer mixed Evenly, the land is flat and meets the requirements of drip irrigation plots.

[0038] 2) Precise proportioning of fertilizers: Use movable fertilization and pesticide application devices to fertilize and apply pesticides. The specific operation method is to add the amount of fertilizers or chemicals that need to be applied to the electric sprayer (20 liters), and inject water through the water inlet of the drip irrigation supervisor. After fully mixing, quickly enter around the roots of the plants through the water outlet (the connection between the electric sprayer and th...

[0044] Tomato fertilization and root irrigation method:

[0045] 1), land preparation: land preparation, base fertilizer application. Apply 3-4 tons of decomposed organic fertilizer per mu, apply 50 kg of compound fertilizer per mu, and 10-15 kg of bacterial fertilizer (Bacillus subtilis) per mu, mix and spread evenly in the soil, plow and harrow and grind to keep the fertilizer mixed Evenly, the land is flat and meets the requirements of drip irrigation plots.

[0046] 2) Top-dressing at the seedling stage: In order to maintain sufficient vegetative growth in the seedling stage, tomato needs to apply nitrogen fertilizer. One hour before the dripping stops, apply 5 kg of urea per acre with water, and apply it once every 7 days. Apply twice.

[0047] 3) Precise proportioning of fertilizers: fertilization and pesticide application using mobile fertilization and pesticide application devices. The specific operation method is to add the required amount of fertilizer or pesticide...

Abstract

The invention discloses a root irrigation and fertilizer and pesticide application device and method. The device comprises an electric sprayer, a drip irrigation hard pipe, a drip irrigation hose, a three-way valve I, a three-way valve II and a plug. The device is convenient to install and use, the pesticide application place, time and frequency of the device are flexible and easy to control, theuse cost of the fertilizer and pesticide application device and the labor intensity of operators are effectively reduced, the pesticide use amount is easy to control, the pesticide uniformity is high,phytotoxicity is not likely to happen, and the pesticide utilization rate is high; and the method is suitable for small-area fields where one or more crops are planted and irrigated in a drip irrigation manner, for different crops and different growth stages of the crops, the pesticide (fertilizer) application amount is different, according to the requirements of the different crops and the different growth periods of the crops for large and medium elements such as nitrogen, phosphorus, potassium and calcium and the occurrence rule of diseases and insect pests, fertilizer or pesticide is fully and evenly mixed, underground drip irrigation of the crops is completed, and the yield and quality of the crops are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a root-irrigating fertilization and pesticide application device and method. Background technique [0002] To maintain or improve crop yield and quality, fertilizers and pesticides are used. At each stage of plant growth, large and medium elements are needed to provide nutrients and maintain nutrient balance. Root topdressing can supplement the nutrients needed by plants, make them absorb quickly, ensure plant vegetative growth and reproductive growth, and improve plant resistance. In summer, as the temperature rises, the pests and diseases of crops and vegetables increase, and root diseases and insect pests are one of the main types. Root irrigation with pesticides is a very effective measure to prevent and control root diseases and insect pests. However, when using pesticides to irrigate roots, you must master the appropriate method. Otherwise, not only will you...
