High-yield wheat fields are often over-sized due to their high density, improper management of fertilizers and water, and they are prone to lodging in the mid-and late-stage. Experience has shown that, before and after the jointing stage, wheat adopts appropriate measures for “seedlings” to prevent lodging in the middle and late stages. The specific measures are:

First, the deep control of Wang: For over-growth, the group of large wheat fields in the rise period of 6 to 9 cm deep cut off part of the root system, weakening the absorption of fertilizer and water, can make Miao Miao become strong, control leggy and invalid Give birth to avoid late lodging.

Second, rolling wheat control Wang: For large groups of Wang Miao wheat, you can get up to the beginning of the jointing process of rolling wheat, can inhibit 1 to 2 section of the internode elongation, the effect of anti-falling Wang Miao significant.

Third, fertilizer and water control Wang: a group of large wheat fields, in the process of getting up to jointing should be appropriate to control the water and fertilizer, when the first quarter of wheat has been fixed, the second quarter of hand touch feel hard, then top-dressing watering. It can control the internode elongation of the base and reduce the invalid tillering, so that the plant dwarfing seedlings are beneficial to prevention.

Fourth, drug control: In the beginning of the jointing stage, spraying chlormeson can reduce the plant height, increase the internode roughness, and can effectively prevent lodging. Usually, 0.3 kg of Chlormequat solution per acre is used before jointing. Evenly spray. Can also be used before the rise, with 15% paclobutrazol 40 grams per acre, spraying 45 kg of water.
