Chemical control and prevention is a new technology for high-yield cultivation of summer maize. At present, there are the following types of regulators used in the test promotion: I. Maize robust 1. Function: Dwarfing the plant and stout stalks. Generally, the plant height can be reduced by 20-30 cm and the ear position can be reduced by 15 cm; the red leaves and the root system can be increased, thereby enhancing the plant's resistance to drought and drought, and the yield. 20% increase from the control. 2, the use of time and method: in 1% -3% of early-onset plants have drawn males, 50% of the tassels will be outcrops (feel the top of the hand with a sense of swelling) medication is most appropriate. One kilogram (30 milliliters) of water per acre is used to spray 20 kilograms of water evenly over the top of the corn. 3, note matters: First, we must grasp the appropriate period, can not be advanced or postponed. 4-5 days in advance will reduce the production of 5%, postponed 4-5 days, increase the rate of decline by 5%; 2 to do not re-spray, no leakage, spray 4 hours after the rain, to reduce the heavy spray. Second, corn dwarf fullness: is a kind of super-concentrated compound preparation, rich in special regulators, amino acids and many trace elements, can inhibit mad grow, promote root development, enhance photosynthesis, so that plant stem diameter, leaf thickness, root Strong, resistant to lodging, improve pollination rate, so that corn sticks large, grain full, but also inhibit a variety of diseases, can increase production by 20% -35%. When 6-10 leaves of corn are sprayed, 20 ml of 30 kg water is sprayed per acre. 3. Yudele: A new type of corn resistant anti-increase and anti-reverse production agent. After use, it can increase root length, root height and root length, shorten the internode length of stem base, dwarf plant height, thicken stem, and greatly improve resistance. The ability to fall can also prevent disease, drought, and flooding, and generally increase production by more than 30%. For 6-11 leaves, spray 25 ml of water per acre. Fourth, Jindele: a new type of special corn conditioning agent, can shorten the length of the internodes, increase the length of straw, dwarf plant height, can reduce the ear position 15-20 cm, thus resistant to lodging. Generally when 7-11 leaves of corn are used, 1 bag (30 ml) of water is used to spray 15-20 kg of water per acre. V. Jade gold: The latest corn-specific high-tech products can reduce the ear position and plant height and resist lodging, can reduce empty culms, spikelets, and anti-bald tip, and can also promote early maturation for 5-7 days, generally increasing production by more than 20%. . When 6-10 leaves (plant height of 0.5-1 m), use 2 sprays (10 ml each) for 30 kg of water per acre. 6. Chemical Control No.2: It can make corn stems tough, with well-developed root system and enhanced lodging resistance. It can also reduce plant height and ear position by 10-12 cm. It can also make the blade flush, increase planting density, and generally increase the yield by 15 %-30%. Before booting, 20% of 25-30 ml of chemical control 2 was used per acre, and 30-40 kg of water was applied to the top leaves of the plants. Seven, paclobutrazol and mozzinine: (1) paclobutrazol: generally in the 5-6 leaf stage, with 50 grams of paclobutrazol 50 kg of water spray. (2) Mighty prime: In the big bell season of corn, 20-30 milliliters are used per mu, and 40 kilograms of water is sprayed, which generally can increase production by 10%. In addition to the above-mentioned several agents, there are many, such as the CommScope 6 (corn resistant), gold inlaid jade, etc., all have the effect of increasing yield.
