2. Reduce the administration of diammonium phosphate. Nitrogen, phosphorus, potassium ternary compound fertilizer should be used, or local cotton special formula fertilizer should be used, or 40 kg of nitrogen, phosphorus and potassium compound fertilizer can be used as base fertilizer. Adding 2 kg of Luhong No. 1 powder when applying other compound fertilizer can improve the ability of cotton to resist dryness, verticillium wilt and blight, and effectively solve the problem of dead seedlings.
3. Use 100 kg of cake fertilizer per acre and 40 to 50 kg of biological fertilizer to make the base fertilizer. In the case of base fertilizer, organic fertilizers such as cake fertilizer, bacterial fertilizer and two-thirds of compound fertilizer are turned into the ground, and one-third of the compound fertilizer is applied to the surface with the sputum, which is beneficial to the utilization of nutrients in the cotton seedling stage.
4. Stable application of bud fertilizer. The bud fertilizer can apply a small amount of compound fertilizer, generally 8 to 10 kilograms per acre, to achieve a stable purpose.
5. Reapply flower bell fertilizer. More than 80% of the nutrients needed for cotton are in the flowering and bolling period, so it is necessary to re-fertilize and apply 20 kg of urea per acre to meet the needs of cotton for nutrients.
6. Apply top cover fertilizer. Cotton has been found to have premature aging before the top of the autumn peach, and it should be applied with 8-10 kg of urea watering to prevent premature aging.
7. Skillfully apply foliar fertilizer. In order to meet the needs of cotton for medium and trace elements, especially for boron, zinc and other elements, and to reduce deficiency, it is necessary to apply foliar fertilizer after cotton growth, and use Luhong Huisheng dew-face fertilizer to spray. After the bud period, the special foliar fertilizer of Luhong Jinkla cotton is sprayed once every 7 days, and even sprayed 3 to 4 times, which can increase the weight of the bell, promote growth, reduce the phenomenon of falling and falling, and have a significant increase in production.
Solar road light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery, gel battery) to store electrical energy, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps.
Solar road light working principle
1. Using the microcomputer intellective controller to transfer the light energy to electrical energy.Easy to install since to wiring and trenching,energy conservation and environmental protection.
