After the cultivation and soil preparation is performed before the harvest, the soil shall be sown and ploughed immediately, and the soil shall be ploughed in time; it shall be deep, thorough, broken, flat, solid, and full; that is, deep plowing, deep plowing, deepening of the tillage layer shall be adopted, and the soil shall be thoroughly pulverized. Smooth ground, good permeability, adequate bottom sill; winter wheat during the fertility without local water, the same plough depth, water retention, create good conditions for the sowing and emergence of wheat; land with irrigation conditions, the ground requires height difference No more than 3.3 cm to facilitate uniform irrigation; conditional areas can be cultivated, 120 cm wide and 10 cm high.
The total amount of fertilizing fertility is generally 4.5-75 thousand kilograms of organic fertilizer per hectare (or 15,000 kilograms of cooked chicken manure), 240-270 kilograms of chemical fertilizer-free nitrogen, 173 kilograms of phosphorus pentoxide, and 113-150 kilograms of potassium oxide. 15 kg of zinc sulfate and 7.5-15 kg of borax. Of the total amount of fertilizer mentioned above, all organic fertilizers, 50% of chemical fertilizer pure nitrogen, 70% of phosphorus pentoxide, all of potassium oxide and zinc sulfate, and borax are all used as base fertilizers, spread evenly on the ground before plowing, and then plowed. One-to-one soil; 30% of phosphorus pentoxide is applied to the lotus root with a series of chemical fertilizers; 50% of pure nitrogen is reserved for the top-dressing period.
The selection of improved varieties of wheat should have the characteristics of high yield, stable yield, high quality, resistance to stress, and strong adaptability. Selection of improved varieties should be based on the local natural climate, cultivation conditions and farming systems.
Seed processing before sowing screening seeds full, uniform, without impurities in order to ensure seed nutrition is adequate, neat seedlings, seedlings full, seedling strong; seed dressing for local seedlings, or seed coating agent The special seed coating agent for wheat contains disease-preventing and insect-repellent agents, trace fertilizers and growth regulators, which are conducive to the comprehensive prevention and control of pests and diseases and the cultivation of strong seedlings; 40% methylisosaloxphos, or 50% phoxim, can be used to control underground pests. Seeds of 0.2% seed dressing; prevention of total erosion, sheath blight or seedling stage rust, powdery mildew, available 20% triadimefon, or 10% hydroxycinadin or rick rust, according to the seed amount of 0.15% ~ 0.2% seed dressing.
Suitable sowing is generally planted from September to mid-October. According to the local climate, seven soil fertility, terrain and other characteristics to adjust.
Suitable for close-growing large panicle varieties with low tillering rate in general tillers, and 195-2.25 million hectares per hectare of basic seedlings. The middle panicle type with high spike-forming rate and basic seedlings of 105-1.5 million per hectare; The seeding rate is calculated based on the seed weight and the field seedling rate. The sowing amount is accurate, the row spacing is the same, the seeding is uniform, the depth is the same, and the seeding is neat.
Seedling management 1. Seedling replanting seedlings, seedlings to fill the shortage after the emergence of wheat seedlings to check seedlings in a timely manner, the lack of seedlings off the ridge of the wheat field to replant as soon as possible, and resolutely put an end to more than 10 cm seedlings and broken ridge phenomenon; if the seedlings grow to At the 3rd to 4th leaf stage, there are still missing seedlings and broken ridges, which can be combined with sparse seedlings and seedlings to transplant seedlings once; after the rain, the loosing soil is loosened, the compaction is removed, ventilation is ensured, and root growth is promoted.
2. Before cultivating and pouring winter water before cultivating the cultivating soil in the cultivator, timely cultivating, deep-rooting and cutting off the roots to promote the development of the root system can increase the temperature, protect the grasshopper, weed the grass, break the compaction, and have the effect of promoting the control of the shoots before the winter. The depth of the earthworm is about 10 centimeters. Afterwards, the earthworms will be leveled and compacted, followed by pouring winter water to prevent wind damage and freezing. In particular, when the wheat comes out of seedlings and rains, winter irrigation, or other causes of soil compaction, it is necessary to carry out timely demarcation. To promote healthy growth of roots and seedlings. 2 Early spring cultivating early spring till returning to the green stage, all types of wheat fields should be cultivated with cultivator, to increase the temperature and promote seedling early; Before the winter, the wheat fields without cracking and cracks in the field can be repressed at the right time to seal cracks and prevent and reduce the freezing and killing of dead seedlings in early spring. .
3. Suppression, repression, and repression can crush the clods and seal the cracks, so that the soil and the roots are closely connected, which is conducive to the absorption and utilization of water by the root system, reducing the evaporation of water, maintaining a good soil moisture content, and preventing the freezing of the wheat seedlings; When the wheat fields with many plowed soil layers and suspended soil are to be repressed before winter, they will be able to disintegrate the stones and sink the soil and promote the growth of seedlings. In addition, for some overgrown wheat fields, they can be suppressed before and after the beginning of winter to suppress The growth of seedlings on the ground makes Wang Miao grow strong.
4. Irrigate with water The land with irrigation conditions, pay attention to changes in the weather, and timely irrigate frozen water once before cooling down, will help maintain the seedlings for winter, and prevent animals from trampling during winter.
5. Weeding and disease prevention In early rainy weather conditions, prevention and pest control and weed control were emphasized, in particular control of sheath blight and underground pests. After the first year of the year, it will maintain a good sensation to postpone the first time in the spring to benefit the spring tube.
