Recommended lodging-resistant wheat varieties, so growers no longer worry about seed selection

Lodging is a phenomenon in the mid-to-late growth stage of wheat in which, due to climatic factors or improper cultivation measures, wheat lodges over large areas, seriously affecting wheat maturation and causing yield reduction. So what lodging-resistant wheat varieties are there?

1. Lodging-resistant varieties

In high-yield wheat areas, the main priority is to select varieties with strong stress resistance, good overall traits and lodging resistance. Such as Yumai 18, Wenmai 4, Jimai 38, Jinmai 48, Wanmai 26, 28, Zinong 033, Lumai 22, 23, Huamai 8, Chuanmai 24, 25, Mianyang 25, 26, Rongmai 1, Chuanongmai 1, Shuman 41, Guifeng 1, Xinong 881, 1376, Xindong 18, 19, 20, etc. In spring wheat areas, lodging-resistant spring wheat varieties such as Jinmai 13, Kenhong 13, Kenjiu 5, Longmai 23, Yunlong 1, Longchun 15, Ningchun 21, Ningchun 22, Longchun 8139, Dingfeng 3, etc. can be selected. The proportions of the various high-yield varieties should be coordinated to achieve a rational layout, so that yields do not decrease in disaster years and are even higher in years with favorable weather.

2. Fertilizer and water management

In high-yield wheat fields, it is essential to water promptly and well at the winter water, jointing water and grain-filling water stages, and generally not to water at the green-up stage or the wheat-yellowing stage. In spring, during the green-up and standing-up stage, the focus should be on control, restricting fertilizer and water; water again after the second leaf from the top emerges and after jointing, and topdress as appropriate. Make every effort to shorten the length of the basal internodes; a first internode length of 4.5—5.7cm and a second internode length of 7.6—8.5cm gives relatively strong lodging resistance. If watering is needed later, be sure to follow the weather forecast and adhere to the principle of not watering before wind and rain and stopping watering when wind and rain occur, managing fertilizer and water scientifically.

3. Pest and disease control

For wheat sheath blight, powdery mildew, aphids, etc., adopt measures based on prevention first and integrated control. Once the control threshold is reached, spray promptly to increase wheat's stress resistance and lodging resistance.

Although wheat lodging has a very large impact, lodging can be effectively resisted through various techniques to increase wheat's immunity. If lodging does occur, it must also be remedied promptly to avoid large-scale yield reduction.
