Wheat Spring Management Technology
In view of the characteristics of spring wheat seedlings and soil moisture, the theme of wheat management in early spring is to promote seedlings, strengthen seedlings, and contend groups. The specific measures should be based on warming up the plots, keeping the seedlings and promoting seedlings as the starting point, properly operating fertilizers and water as an important means, doing a good job in classification management, and achieving early transformation and upgrading of the seedlings. In order to do a good job in wheat spring technology management, the following aspects should be mastered:
1. Management of dry wheat fields. In wheat fields with ploughed soil moisture below 60%, they must be watered immediately before and after the return of green wheat, combined with watering for topdressing, generally mu recovering urea from 10 kg to 15 kg. According to the situation of the seedlings and the fertilization of the previous year, the amount of fertilizer was adjusted appropriately. Large amount of fertilizer can be appropriately reduced in populations, and the amount of fertilizer in small groups and weak individuals can be appropriately increased. After watering, it is necessary to carry out plan drawing in time to break the compaction, increase the temperature of the soil, and promote the early and long growth of the wheat seedlings.
2. Type II and III wheat management. Small, weak individuals, but can normally turn green, the second and third types of wheat fields, before and after the return of green should be mainly cultivators, planning, multiple shallow rake, fine rake, to prevent injury to the root and the pelagic pressure seedlings. In terms of water and fertilizer management, it is proposed to delay the arrival of spring water for early spring and return to greening, generally after the soil has been thawed, it can be watered. Combined with watering, urea can be recovered from 12 kg to 15 kg. This can consolidate the delivery before winter, promote spring delivery, increase the root system, increase the leaf area coefficient, so as to achieve the purpose of increasing the population and increasing the number of acres.
3. A kind of seedlings and wheat fields management. In the field of good seedlings with good lyrical conditions, management should be based on planning, deep plowing, control of ineffective delivery, reduction of unnecessary consumption of nutrients, and delay of spring and water if the situation permits, and the period of time after wheatman rises up. Or early jointing, combined with watering mu urea 10 kg to 12 kg.
4. Control of pests and weeds. In early spring wheat disease and insect pest control focuses on sheath blight, spider mites, and weeds in wheat fields. Based on the basic characteristics of the early spring wheat ecological structure, it focuses on the protection and utilization of beneficial organisms in wheat fields, and is based on agricultural control, supplemented by chemical control. Specific prevention and control measures and prevention and control measures are as follows: 1 Wheat sheath blight, prevention and control index is 15% of the diseased plants in the field, generally 20% of the mu is used to spray 50 kg of powderying emulsion 50 kg water, every 10 days to 15 days Spray once. 2 Wheat spider mites, the control index is 200 per single foot per row, mainly agricultural measures in prevention and control, combined with watering and shaking down the wheat field, serious can spray dicofol. 3 Weeds in wheat fields, combined with wheat field planning, manual weeding, weeds, severe plots can be sprayed with herbicides for chemical valerian, general mu with 10% of the Maile 8 g or 90% of the stars 1.2 g Spray 50 kg of water.
5. Fine-tuned cultivation of high-quality wheat fields. According to the impact of water, nutrients and other environmental conditions on the species, in the early spring management should pay attention to the following several technical aspects: First, to promote water-saving irrigation technology, reduce the number of watering, pouring a good key water; Second, as early as possible to minimize nitrogen fertilizer The well-abundant plots are usually chased after the jointing period; the third is the manual drafting and elimination of weeds. Other management measures are basically the same as common wheat.
