How to prevent wheat seedling death in winter? Keep these measures in mind
In recent years, freezing damage to wheat has occurred every year in our county. Apart from the factors of the wheat variety itself, the main cause is that winter management measures are neglected by farmers. In order to reduce the occurrence of freezing damage to wheat this year, the technical advisor specifically put forward the following technical

Wheat fertilization has its particularities: pay attention to less phosphorus and more potassium
Applying excessive phosphorus to wheat first of all increases costs. This year diammonium phosphate is quite expensive, with the retail price of 64% exceeding 3900 yuan/ton. Phosphorus is essential, but there is no need for excess. Empirical data shows that using 40-50 kg of a ternary compound fertilizer containing 15%-20% pure phosphorus per mu as a base fertilizer generally prevents phosphorus deficiency.

Eight Key Points for Managing Wheat During the Wintering Period
From emergence to wintering, the growth characteristics of winter wheat are growing roots, growing leaves, growing tillers, and completing the vernalization stage, that is, "three growths and one completion," with the growth center being tillering. The central task of field management is, on the basis of preserving seedlings, to promote root growth and increase tillering, so that weak seedlings become strong and strong seedlings grow steadily.

Remedial measures for yellowing and withered wheat leaves
Apply 70% isoproturon to wheat, and on the third day after treatment a cold wave hit; now the wheat leaves are yellowing and withering. Can it recover after some time, and are there any remedial measures? Isoproturon reduces the cold resistance of wheat seedlings; if severe frost occurs after application, the seedlings are prone to

How to manage wheat in winter? Master these five key points
To do a good job in the field management of winter wheat, the following measures should be focused on: First, strengthen the management of three-category seedlings. For three-category seedlings, the favorable opportunity before winter freezing should be seized to give priority to management and promote root growth. Loosen the soil by hoeing in time to increase soil temperature. For late-sown wheat fields with good subsoil moisture,

Wheat blossom midge can be controlled by broadcasting pesticide-treated soil at the booting stage
The wheat blossom midge overwinters as mature larvae in round cocoons in deep soil and can remain dormant for many years. In spring, when the soil temperature at 10 cm rises to about 7°C, which is when wheat begins jointing, the larvae break out of their cocoons and move toward the soil surface. In mid-April, wheat enters the booting stage, and the larvae

Sharing Experience on Increasing Corn Yield Through Properly Delayed Harvest
The technique of increasing corn yield through late harvest is, on the premise of not affecting the timely sowing of wheat, to fully extend the corn grain-filling period, increase grain weight, raise corn yield, and improve corn varieties. At the same time, if the land must be cleared for the next crop and early harvest is necessary, the stalks can be harvested together with the ears and placed
