The focus of classification management before and after wheat thriller
After the startling sting, wheat has entered a critical period of returning to green jointing and spring field management. It is also a season of alternating cold and warm and frequent climate changes. The probability of natural disasters such as cold spring, continuous rain, and other natural disasters is also high. It is recommended to do a good job of classification management of wheat according to the actual situation.
1. Weak seedlings. If the weak seedlings are not promoted by effective measures in early spring, it is easy to form "small old seedlings". The morphological characteristics of the "small old seedlings" are similar to those of weak seedlings before winter, or even more serious. The main goal should be to promote roots, increase tillers, and strive for early onset. For weak seedlings with good moisture content, the key measure is to loosen the soil. The turning green water should be postponed from late March to early April, and topdressing should be reapplied appropriately in combination with irrigation. ******Spray the new high-fat film to form a polymer film to keep warm and moisturize to prevent pathogen infection.
2. Strong seedlings. Strong seedlings in early spring should be dominated by deep hug loose soil. In mid-March, deep field tillage (over 2 inches) or soil cultivation measures should be taken to suppress the growth of small tillers and accelerate the polarization of tillers. If the total number of stems does not exceed the above indicators from late March to early April, they should be top-dressed and watered in time before getting up, and photosynthetic nutrient film fertilizers should be used in conjunction to help absorb more light fertilizers and conventional fertilizers.
3. Wang Miao. For the prosperous seedlings that are too large before winter, the field is closed, and the fields are high and steep, the seedlings should be thinned with nail-tooth rake and heavy rake as soon as possible, or deep field tillage should be adopted to cut off some secondary roots to prevent small tillers from breeding and prevent large tillers. Steep and long. If the wheat seedlings are too prosperous, the top dressing and watering can be postponed until the tip of the flag leaf is exposed. The timely spraying of Cihuawang No. 3, the assimilation induction promotes the transmembrane signal conversion of plant cells, forcing the apical exuberant nutrients to return in a large amount, and the main nutrient of the main nutrient turns to the developmental system.
