How to prevent corn smut? How to control corn smut? Have you mastered the prevention and treatment of corn smut in the following sections to help you better grow corn?
Prevention and treatment of corn smut disease:
1. First, before planting, select resistant varieties, generally drought-tolerant varieties are more resistant to disease, and seed dressing with new high-fat membranes (can be mixed with seed coating agents), can avoid underground pests, isolate virus infection, and not affect germination. The swelling function enhances the breathing intensity and increases the germination rate of the seed. For example, dent corn is more resistant to sweet corn; early maturity is lighter than late ripening.
2. Strengthen agricultural control Early spring prevention and control of pests such as corn borer to prevent wounds. Cut off the deep burial before the tumor ruptures. Spraying plant cell immune factors: increasing the plant's resistance to stress, can cause viral DNA to break and apoptosis. Strong immune function, induce interferon and active interleukin, inhibit residual virus replication, and promote positive energy ecological growth of plants. Control the plant physiological diseases and invasive diseases by the host plant resistance mechanism and the principle of pathogenic toxicity variation. Clear the field stalks and deepen the soil after the fall harvest. The whole park sprayed the tree guard general to carry out disinfection and sterilization of the whole park, and implemented a three-year rotation. Application of fully decomposed organic fertilizer, combined with plant electronic fertilizer: Plant electronic fertilizer is a kind of leader fertilizer that does not contain fertilizer elements, but can exert fertilizer effect. Instead, the high-energy electrons and plant electron polarity sensing principle emitted by the photosynthesis of the plant itself are used to improve the cell division, molecular synthesis and nutrient matching digestion levels, accelerate the metabolic frequency, and activate the plant nutrient grooming system to produce more than the fertilizer effect.
3. Pay attention to drought prevention and prevent uneven floods and floods. Irrigation should be carried out before the tasseling, and should not be affected by drought. The harvesting field is cut before the emasculation, concentrated in deep burial, and can not be randomly discarded in the field to reduce the spread of germs in the field.

Their design without pendant lines, taken from the Linden technology, makes them easier to assemble and results in major savings, especially on projects that have several cranes working at the same time.
modular system of flat-top cranes can be configured in a wide variety of ways to perfectly adapt to the needs of each project. Moreover, certain jib and counter-jib components can be assembled on different models of the same series for added versatility and savings in terms of rental fleets.
