Description
Technical Field
The invention belongs to the technical field of pesticide fertilizers, and particularly relates to a slow-release pesticide fertilizer suitable for Xinjiang cotton and a preparation and application method thereof.
Background
The pesticide fertilizer is a novel ecological compound fertilizer formed by mixing pesticide and fertilizer according to a certain proportion formula and stabilizing the fertilizer and the pesticide in a specific compound system through a certain process technology, and the fertilizer is generally used as a pesticide carrier. For the sustainable development of contemporary agriculture, medical manures are a new attempt to support and drive modern agriculture with powerful technology. The pesticide fertilizer can combine two operation steps in the field, which not only saves labor force, but also reduces time and energy consumption.
Cotton is one of the main economic crops in Xinjiang, and requires a large amount of nutrients such as nitrogen, phosphorus, potassium, medium and trace elements in the whole growth period, and the nutrient elements required by cotton are applied along with water drops along with the popularization of drip irrigation fertilization. Under the condition of not considering the influence of environmental factors, the fertilizer consumption is increased continuously in recent years, the yield is not increased obviously, and even the decline trend appears. The reason is that the yield of cotton is limited due to low utilization rate of fertilizer. Xinjiang belongs to calcareous soil, the moving distance of phosphate in the soil is only less than 10cm when phosphate fertilizer is applied by drip irrigation, most phosphate and calcium in the soil form ineffective phosphorus, and the root system of cotton can only absorb little phosphate fertilizer.
Meanwhile, in recent years, aphids have great harm to cotton, foliar spraying medicaments are mainly used for prevention and treatment, and the aphids are sprayed in two modes, namely a locomotive mode and an unmanned aerial vehicle mode. However, the spraying of the pesticide can kill aphids and also kill natural enemies, so that when the aphids explode, the use amount of the pesticide is increased but the effect is not obvious. The application of the pesticide in the interval of three to five causes the increase of the planting cost, so that the closed pesticide application can protect the natural enemies, prevent the outbreak of aphids and reduce the pesticide resistance of the aphids. There have also been attempts to apply systemic insecticides by drip irrigation, but the effect is extremely weak because of poor control of the concentration. Therefore, the research and development of a pesticide fertilizer for preventing and treating cotton aphids is very necessary.
The existing pesticide-fertilizer particles are mainly used in the inland and mainly aim at pests and diseases of sugarcane, rice and the like, most of fillers are organic fertilizers, inert soil or low-content nitrogen, phosphorus and potassium fertilizers, the requirements of killing pests and providing nutrients cannot be met at the same time, the pesticide-fertilizer particles are extremely large in dosage and poor in effect when being applied and are spread in soil, and most of pesticide-fertilizer particles are not suitable for simultaneous sowing of seed fertilizers due to the fact that the slow release function is not available.
In view of the above, the invention provides a slow-release insecticide fertilizer suitable for Xinjiang cotton and a preparation method thereof.

2. The slow-release pesticide fertilizer particles are applied to the soil by 10-15cm through seed and fertilizer simultaneous sowing, are very close to the root system of crops, and directly act on the root, so that the movement of a phosphate fertilizer in the soil is reduced, the utilization rate of the phosphate fertilizer by the crops is improved, the use amount of the phosphate fertilizer in the later stage topdressing process can be reduced, and the problem of low utilization rate of the phosphate fertilizer caused by the fact that the movement distance of the phosphate fertilizer in the soil is less than 10cm is solved. Meanwhile, when the crops absorb water and fertilizer, systemic monosultap and thiamethoxam are sucked into the plants, and the aphids die after sucking plant juice, so that the purposes of preventing and treating the aphids and protecting beneficial insects are achieved, and the probability of insect pest outbreak in the field is greatly reduced along with the increase of natural enemies.
3. The added citric acid monohydrate can prevent the phosphate fertilizer from reacting with metal ions in the soil to form invalid phosphorus, thereby improving the utilization rate of the phosphate fertilizer.
4. The added xanthan gum and polyvinylpyrrolidone can enable the thiamethoxam to be dispersed and suspended in the liquid medicine more uniformly, thereby ensuring the stability of the product.
