In order to seize the bumper harvest of wheat, according to the actual situation this year, the guiding ideology for wheat planting in the central and southern regions of the province is to do a good job of supporting techniques such as cultivation of excellent varieties, formula fertilization by soil testing, fine soil preparation, adequate planting with enough leaves, and suppression after sowing.

First, choose a good variety

The varieties suitable for planting in the South-Central Wheat District include 邯6172, 邯mai 12, Liangxing 99, and Jimai 22.

Second, promote formula fertilization

When applying fertilizers, we must adhere to the principles of organic and inorganic combinations, stabilizing nitrogen, controlling phosphorus, supplementing potassium, and matching micro-organisms, increasing organic fertilizers, and vigorously promoting soil testing and formulating fertilization techniques, and rationally applying fertilization according to yield targets and soil nutrient determination results. Words, plots of more than 600 kilograms per mu, Mushi 7-8 kilograms of nitrogen fertilizer, 8-10 kilograms of phosphate fertilizer (P2O5), 5-8 kilograms of potassium fertilizer (K2O), 500-600 kilograms of land per mu, Mushi nitrogen fertilizer (N) 6.5-7 kilograms, phosphate fertilizer (P2O5) 7-9 kilograms, potassium fertilizer (K2O) 4-6 kilograms; 400-500 kilograms per mu plots, M fertilizer nitrogen (N) 7-8 kilograms, Phosphate (P2O5) 6-8 kg, Potassium (K2O) 3-5 kg. In addition, zinc, boron and other trace elements are applied together.

Third, fine soil preparation, implement straw return

When the straw is returned to the field, the straw must be crushed twice. The length of the straw should be less than 5 cm. The rotation depth should be more than 15 cm. The rotation should be twice. For more than three years, the rotation or no-tillage should be 30 times. More than centimeters; after ploughing, the land will be pressed and grounded, and the land will be leveled, the emptiness will be reduced, and the land will be finely grounded. Do not sow the soil after the soil has been ploughed.

Fourth, do a good job of seed dressing

Pre-sowing pesticide seed dressing can effectively control the occurrence of soil-borne, species-borne diseases and underground pests. Generally used in 3% of the enemy's flannel 250-300 ml +2.5%, 100-200 ml of music, 500 ml of water, mixed with 50 kg of wheat, can prevent wheat full-bleed disease, powdery mildew, root rot, and withering Diseases and other diseases. Use 50% phoxim EC 100 ml, 2-3 kg water, mix 50 kg of wheat, mix and boring for 2-3 hours, dry and sow.

Fifth, appropriate amount of appropriate sowing

The proper sowing of wheat is conducive to safe wintering of wheat and the cultivation of pre-winter seedlings. The suitable sowing date for wheat is from October 7 to October 15. It should be broadcasted before the frost falls at the latest, and the sowing rate per mu is 10-12 kg. According to the level of soil fertility, the amount of sowing should be adjusted appropriately. The variety with high tillering rate should appropriately reduce the sowing rate, and the variety with low tillering rate should be increased appropriately. After the planting of the land after October 15th, each time the delay of 1 day, the basic seedlings of the mu were increased by 10,000 on the original basis, that is, the per mu sowing amount increased by about 0.5 kg.

Six, fine sowing

The relative soil moisture content suitable for wheat sowing is about 80%. If there is not enough precipitation before planting wheat, it is imperative that the crop be harvested, and no robbers should be planted. If the rainfall during the sowing season is too high, the soil water should be dispersed until it reaches the required humidity for sowing. After sowing, the clay field can be planted first and watered immediately after sowing. When planting, the operator is required to adjust the seeder. When the field operation, uniform speed and slow speed shall be used for sowing. The seeding depth shall be 3-5 cm.

Seventh, fully dense planting, suppression after sowing

The three dense and thin, four dense and thin, the size of the ridges and other planting patterns were changed to wide-row and other planting planting patterns in order to increase field uniformity and increase the effective basic seedlings. At the same time, it is necessary to ensure that all seedlings are planted on the edge of the ridge where there are few seedlings and seedlings. After sowing, depending on the soil moisture, use repressors such as crackers or stone mulches to suppress the grass. Sunny and noon sowing should be performed. The plots with slightly less sensation should be suppressed immediately; in the morning, evening or cloudy days, the plots with good sensation can be slightly pushed back. Repression; plots with particularly adequate lyrics can be selected for repression before or after emergence.

VIII. Pest control

Before the emergence of wheat, 10% imidacloprid 1000 times solution or other pyrethroid insecticides can be sprayed on the edge of the field and the top of the field to spray 5-10 meters wide, to prevent the migration of insects such as Laodelphax striatellus. After emergence of wheat, there are 5 soil maggots per square meter or more than 10 smuts of Laodelphax striatellii, and 25% of chlorpromazine can be sprayed at 1000 times to prevent the occurrence of wheat virus disease.
